Thus, when the swinging rod 101 is rotated by the output shaft 6a, the swinging eccentric cam 101a is reciprocated in the front-rear direction by the eccentric rotation of the swinging eccentric cam 101a, thereby reciprocatingly swinging the solitary rotating arm 102 in the front-rear direction. .
With the above configuration, when the output shaft 6a rotates, the rotating rod 100 is reciprocated in the front-rear direction, and along with this reciprocating movement, the soli-rotating arm 102 reciprocally rotates in the front-rear direction in plan view. Since the swinging sour 29 provided on the arm 105 can be rotated in the front-rear direction in a plan view, the soil can be dug reliably from the base side to the end side of the swinging sour 29. The soil is prevented from resisting when the onion is pulled out, and the work efficiency is improved.
In particular, since the soil around the onion planted at a position away from the mounting base of the swinging soiler 29 in the body inner direction, that is, the onion planted near the center in the left-right direction of the kite, can be easily unwound. The efficiency is improved, the onion is prevented from being left unchecked, and the time and labor for the operator to manually harvest the onion are reduced.
In addition, since the swinging sour 29 rotates about the left and right side of the swinging arm 102 as a fulcrum, the amount of rotation increases toward the other left and right sides of the swinging soy 29, so that the width before and after unraveling the soil becomes wider. The soil is dug more reliably and the efficiency of the onion pulling and harvesting work is improved.
Further, when the output shaft 6a rotates, the rocking rod 101 is reciprocated in the front-rear direction, so that the rocking soiler 29 can be swung in the front-rear direction. As a result, the onion is prevented from being pulled out and damaged, and the operator does not need to dig up the onion, thereby reducing the labor of the operator.
Furthermore, the rocking rod 101 is swung in the front-rear direction by the rocking rod 101 and the rocking sour 29 is swung in the front-rear direction by the rotating rod 100, so that Since the soil can be unraveled reliably, it is possible to harvest multiple onions without losing pulling out, improving work efficiency and eliminating the need for the operator to manually harvest the remaining onions, Save time and effort.
The swinging soiler 29 enters the cage as the aircraft moves forward, and unravels the dredged soil from the soil. In order to prevent it from coming into contact with the onions planted in the soil, Pass through. When the rocking soy 29 passes under the onion, the rocking soy 29 can be brought into contact with a thin hair root extending from the lower part of the onion into the soil and the root can be cut when the soil is unwound. Therefore, the labor of removing the hair root from the onion after harvesting is reduced.
However, in the conventional configuration, when the soil is difficult to unravel due to soil quality, onion growth state, etc., the rocking soiler 29 is located around the onion that is vegetated near the center of the straw away from the mounting base of the rocking soiler 29. Since it does not swing back and forth almost back and forth, the soil is difficult to unravel and the onion is not pulled out, and the roots are not cut, and many remaining roots after harvesting must be removed, which is necessary for the removal work There is a problem that time and labor increase.
The onion root of the onion has innumerable thin roots at the center of the lower bulb, but it grows at a position close to the edible part with commercial value, so it can be removed without damaging the edible part. Requires precise cutting. Therefore, the more beard roots remain, the more time and labor required for the removal work tend to increase.
In the configuration of the present application, the swinging soluer 29 is rotated in the front-rear direction in a plan view by the rotating rod 100, and the end side of the swinging soluer 29 is rotated back and forth more significantly than the base side with the sour rotating arm 102 as a fulcrum. Since it is configured to move, the oscillating soiler 29 can remove the roots of the onion while digging the soil near the center of the reed, thus reducing the labor and time for removing the reeds from the harvested onion. .
Further, in this configuration, a solitary rocking case 107 is provided on the outer periphery of the solitary rotating arm 102, and even if the rocking rod 101 reciprocates the solitary rocking case 107 in the front-rear direction, the solitary rotating arm 102 does not rotate. Since the structure is configured to rotate in conjunction with the rotation of the moving plate 103, the reciprocating rocking in the front-rear direction and the reciprocating rotation in the front-rear direction of the rocking soiler 29 interfere with each other. It is possible to prevent the efficiency of removing the root of the hair from being lowered.
The working height of the rocking solubilizer 29 is such that the connecting holes formed in the soli support arm 105 and the rocking solubilizer 29 are combined, and fixing members 29a such as bolts and nuts are inserted into the connecting holes. However, if the vertical position needs to be changed significantly when adjusting to the height of the ridge or the vegetation position of the onion, the above adjustment method may not be able to cope with it.
In order to solve this problem, in this case, as shown in FIGS. 6 and 7, the left and right sides on the rear side of the body frame 1 and the left and right sides of the drive wheels 84R on the left and right sides are directed downward. The adjustment support plate 108 is provided, and the rear end of the vertical adjustment cylinder 109 is rotatably attached to the adjustment support plate 108. A vertical adjustment lever (not shown) for operating expansion / contraction of the vertical movement adjustment cylinder 109 is provided in the vicinity of the travel operation lever 10. A front end portion of the vertical adjustment cylinder 109 is rotatably provided at a lower portion of the relay rotation arm 110, and a rear end portion of the vertical adjustment arm 111 is provided at an upper portion of the relay rotation arm 110. A front end portion of the vertical adjustment arm 111 is connected to the solar swing case 107.
At this time, the front end of the vertical adjustment arm 111 is located below the vertical center position of the rocker swing case 107 and higher than the soli support arm 105 so as to increase the vertical adjustment amount of the rocking soiler 29. It shall be provided above. Further, the front end of the vertical adjustment arm 111 is constituted by a bifurcated branch support 111a, and a solitary swing case 107 is disposed in a space portion of the branch support 111a. 112 is configured to be able to rotate by making contact with the rocker swinging case 107.
Accordingly, when the vertical adjustment cylinder 109 is expanded and contracted, the relay rotation arm 110 is rotated in the front-rear direction, and the vertical adjustment arm 111 is moved in the front-rear direction in conjunction with the vertical movement of the sor swing case 107. It becomes composition.
The vertical adjustment cylinder 109 may be electrically operated or hydraulic. However, if it is replaced with an expansion / contraction rod (not shown) that expands and contracts when the handle is turned, the labor required for the operation increases, but an energizing cable or transmission Oil pipes are no longer required, and costs can be reduced.
As described above, the operating position of the rocking soiler 29 can be appropriately changed in accordance with the height of the reed and the depth of the soil in which the onion is buried, so that the rocking soiler 29 contacts the onion in the soil. Damage to the product, and the commercial value of the onion is improved.
Moreover, since the rocking soiler 29 is too far from the onion in the vertical direction, the soil around the onion cannot be unraveled, and the onion can be prevented from remaining on the field without being pulled out, so it is necessary for the operator to harvest the onion manually. The labor of the operator is reduced.
Further, since it is possible to prevent the beard root of the onion from being drawn and harvested without being cut, the time and labor required for the work of removing the root from the onion after harvesting can be measured.
With the above configuration, under the four-row planting work conditions, the soil around the two onions is dissolved to facilitate pull-out harvesting, and the roots are removed to reduce the labor required for post-harvest preparation work. It becomes possible to do.
Next, the structure which cuts the stem and leaf part of the onion extracted from the field at the height set by the operator and moves it to the field scene will be described.

Left and right laterally raised belts 39, 39 are wound around the left and right laterally raised belts 39, 39, and left and right laterally raised frames 37, 37 are parallel to the left and right laterally raised frames 37, 37. By providing the cover 40, 40, a lateral pulling device 41 is configured.
The laterally raised lugs 39, 39 a... Provided on the left and right laterally raised belts 39, 39 are arranged at positions where their tip portions are close to the drawing conveyance area of the drawing conveyance device 19 and are not in contact with each other.
With the above configuration, the lugs 39a, 39a,... Are prevented from coming into contact with each other, so that the stems and leaves caused by the impact of the contact are prevented from falling, and the onion is surely placed on the field by the pulling and conveying device 19. The work efficiency is improved.
In addition, upper ends of the relay transmission cases 42 and 42 in which the left and right second universal joints (not shown) are provided are provided on the lower side of the left and right output transmission cases 34 and 34, and the left and right relay transmission cases 42 and 42 are provided. Left and right shoulder-aligned drive pulleys 43, 43 are provided at the lower end of each. The left and right shoulder alignment drive pulleys 43, 43 are respectively provided with front end portions of left and right upper shoulder alignment frames 44, 44 and left and right lower shoulder alignment frames 45, 45 at the upper and lower portions thereof. 44, 44 and left and right lower shoulder alignment frames 45, 45 are respectively mounted with left and right shoulder-aligned driven pulleys 46L, 46R so as to be rotatable, and with left and right shoulder-alignment drive pulleys 43, 43. The left and right shoulder alignment belts 50, 50 are wound around the driven pulleys 46L, 46R in an endless manner.
Further, as shown in FIG. 11 to FIG. 14, the driving force from the output shaft 6a is provided between the output shaft 6a on the left and right sides of the transmission case 3 and on the inner side of the body of the traveling transmission case 80R, that is, on the other left and right sides. The first cutting transmission case 300 that transmits and obtains the above is provided in a forwardly inclined posture. The first cutting transmission case 300 includes a first cutting drive sprocket 301 mounted on the output shaft 6a, a first cutting driven sprocket 302 mounted with a first relay transmission shaft 304, and the first cutting driving sprocket 301. A first cutting transmission chain 303 wound endlessly around the first cutting driven sprocket 302 is housed.
One end of the left and right sides of the first relay transmission shaft 304 is protruded to the outside of the first cutting transmission case 300, and is transmitted to the first relay transmission shaft 304 by receiving a driving force from the first cutting transmission case 300. A second cutting transmission case 305 is disposed so as to be rotatable in the vertical direction. Accordingly, the second cutting transmission case 305 is disposed closer to the left and right sides of the machine body than the first cutting case 300.
The second cutting transmission case 305 includes a second cutting drive sprocket 306 mounted on the first relay transmission shaft 304, a second cutting driven sprocket 307 mounted with a second relay transmission shaft 309, and the second cutting drive. A second cutting transmission chain 308 is wound around the sprocket 306 and the second cutting driven sprocket 307 in an endless manner.
Then, a base side of a cylindrical cutting transmission gear case 310 that is long in the left-right direction of the body is provided at the left and right other end of the second relay transmission shaft 309, that is, an inner end of the body, and the end of the cutting transmission gear case 310 is provided. On the part side, a cutting output shaft 311 for transmitting a driving force downward is provided. Further, a circular foliage cutting blade 312 that cuts the foliage of the onion being transported is attached to the lower end of the cutting output shaft 311. The foliage cutting blade 312 may be a blade having a sharp outer peripheral edge or a saw blade having a fine protrusion continuously formed on the outer peripheral edge.
The cutting transmission gear case 310 rotates with the second relay transmission shaft 309, an output bevel gear (not shown) attached to the relay transmission shaft 309, and the cutting output shaft 311 in mesh with the output bevel gear. An input bevel gear (not shown) is provided.
Further, a base portion of a U-shaped slide frame 313 in a side view is mounted on the left and right sides of the body frame 1 and at a position that is substantially horizontal with the farm field, that is, in the vicinity of the center in the longitudinal direction of the body. The slide frame 313 has a rear rising inclined portion located on the rear side of the aircraft toward the upper side, and a linear portion protruding from the rear rising inclination portion toward the rear side of the aircraft. It is located above the second cutting transmission case 305 that is rotated upward as much as possible, and the straight line portion is assumed to be substantially horizontal with the field.
Then, a long hole 313a in the vertical direction is formed in the rearwardly inclined portion of the slide frame 313, and a holding bolt 314 that holds the posture of the cutting transmission gear case 310 through the long hole 313a is inserted. When the holding bolt 314 is a butterfly screw, the operator can easily operate it by hand, and the angle adjustment operation of the foliage cutting blade 312 by the rotation of the cutting transmission gear case 310 can be easily performed.
The vertical length of the long hole 313a is a length that falls within the range of the vertical length of the rearwardly inclined portion of the slide frame 313, that is, a length that becomes shorter. Further, when the holding bolt 314 is loosened, the cutting transmission gear case 310 rotates about the second relay transmission shaft 309 as a fulcrum, and the cutting action angle of the foliage cutting blade 312 can be changed.
Also, a slide in which a groove portion 315a is formed in the front-rear direction at the center in the left-right direction on the upper surface of the leaflet cover 200 that covers the front and upper sides of the engine 2 and the transmission case 3, which will be described later. A guide plate 315 is provided, and an adjustment knob bolt 316 is rotatably and slidably disposed in a groove 315a of the slide guide plate 315. The adjustment knob bolt 316 is not slid when rotated clockwise, and is slid vertically along the groove 315a when rotated counterclockwise. Further, even when the adjustment knob bolt 316 is most slid to the front side of the aircraft, the operator's hand standing at the rear of the aircraft can reach.
Further, a boss 317 is provided on the outer periphery of the cutting transmission gear case 310, and a screw shaft 318 is provided below the adjustment knob bolt 316. The boss 317 and the screw shaft 318 are cut to move the cutting transmission gear case 310 up and down. They are connected by an interlocking rod 319. The screw shaft 318 is positioned above the cutting interlocking rod 319 and is in contact with the upper surface of the slide guide plate 315. The screw 318 is positioned below the cutting interlocking rod 319 and is in contact with the lower surface. A side clamping plate 320d is provided.
In conjunction with the vertical movement of the cutting transmission gear case 310, the second cutting transmission case 305 also rotates up and down.
When the adjustment knob bolt 316 is rotated in the tightening direction, the upper clamping plate 320u is pressed against the upper surface of the slide guide plate 315, and the lower clamping plate 320d is attracted to the lower surface of the slide guide plate 315. Since 316 cannot slide in the front-rear direction, the vertical position of the cutting transmission gear case 310 is fixed.
On the other hand, when the adjustment knob bolt 316 is rotated in the loosening direction, the upper clamping plate 320u and the lower clamping plate 320d move in directions away from the slide guide plate 315, so that the adjustment knob bolt 316 can slide in the front-rear direction. The cutting interlocking rod 319 moves the cutting transmission gear case 310 up and down by sliding the adjusting knob bolt 316 in the front-rear direction.
As a result, it is possible to change the vertical position at which the foliage section is cut according to the onion harvesting conditions, for example, the variety and growth of the onion, and the drying method of the onion after harvesting. The edible part can be prevented from being damaged and the product value can be prevented from being lowered, and it is possible to pick up the onion from the field by grabbing the uncut leaves and hang the onion in a dry place. improves.
In the above configuration, the cutting transmission gear case 310 is supported by the holding bolt 314 and the adjustment knob bolt 316. However, the foliage cutting blade 311 and a bevel gear mechanism (not shown) that transmits a driving force to the foliage cutting blade 311 are shown. ) Is concentrated on the left and right sides, so that the center of gravity is biased. For this reason, the cutting transmission gear case 310 is easy to swing during vertical movement, and even if the adjustment knob bolt 316 is slid in the front-rear direction, the cutting transmission gear case 310 does not move sufficiently in the vertical direction. Extra force required for sliding in the front-rear direction may be required.
Further, when the weight is applied to one side, a load is applied to the slide frame 313, the cutting interlocking rod 319, and the like, and durability can be reduced.
In order to prevent this, a pair of upper and lower support plates 321 and 321 are provided on the left and right other sides of the slide frame 313, that is, on the inside of the machine body, and substantially parallel to the slide frame 313 between the upper and lower support plates 321 and 321. A slide rod 322 is provided in a posture. Then, slide auxiliary projections 323 and 323 are formed in the cutting transmission gear case 310, each of which has a round hole 323a through which the slide rod 322 passes. Thereby, the foliage cutting device 324 which can perform vertical position adjustment easily is comprised.
As a result, the cutting transmission gear case 310 is configured to move up and down along the slide frame 313 and the slide rod 322 and easily moves in parallel in the vertical direction. 310 becomes difficult to swing, and the vertical position can be easily adjusted.
In the above configuration, the first cutting transmission case 300 and the second cutting transmission case 305 are provided so as to be rotatable up and down, so that the cutting transmission gear case 310 is moved up and down by sliding the adjustment knob bolt 316 in the front-rear direction. Since the first cutting power transmission chain 303 and the second cutting power transmission chain 308 are not loosened, a tension member such as a tension sprocket that acts when adjusting the vertical position of the foliage cutting device 324 to maintain the tension becomes unnecessary. The number of points is reduced and an increase in the weight of the foliage cutting device 324 and thus the entire body is prevented.
Further, when the holding bolt 314 is loosened, the cutting transmission gear case 310 rotates back and forth, whereby the angle of the foliage cutting blade 312 can be changed. Therefore, when the field is inclined upward or downward, the foliage When the angle of the cutting blade 312 is changed, the foliage can be cut in the same manner as in a flat place.
This prevents the foliage cutting blade 312 from contacting the foliage at an angle and prevents the foliage from remaining on the edible portion of the onion, eliminating the need for the operator to manually remove the foliage. The effort is reduced. Or since the foliage cutting blade 312 cuts to the edible portion and can prevent the occurrence of onions that are not suitable for shipment, the yield is prevented from decreasing.
Then, the slide guide plate 315 provided with the adjustment knob bolt 316 is arranged at a position closer to the left and right sides of the leaf cover 200, so that it is on the rear side or side of the handle 8 and follows the advance of the onion harvester. Since the operator can easily reach the adjustment knob bolt 316, when the cutting up and down position of the foliage cutting device 324 is changed, the worker moves to the side of the machine body where the cutting transmission gear case 310 can be reached. This eliminates the need for improved work efficiency.
In addition, since the vertical movement of the cutting transmission gear case 310 is supported at the two positions of the slide frame 313 and the slide rod 322, the cutting transmission gear case 310 is less likely to swing in the horizontal direction during the vertical sliding. Therefore, the force required to slide the adjustment knob bolt 316 is reduced, and the work efficiency can be improved and the labor spent by the operator can be reduced.
Furthermore, since it is possible to prevent the cutting transmission gear case 310 from becoming difficult to move during sliding, the foliage cutting device 324 can be set at a position interlocked with the sliding of the adjusting knob bolt 316, so that the foliage portion is more appropriate. It is possible to cut at a proper position and work efficiency is improved.
In the above configuration, the inclination angle of the foliage cutting blade 312 is determined by loosening the holding bolt 314 and rotating the cutting transmission gear case 310. However, if the farm is on an inclined ground and the inclination angle changes in the middle, the operator needs to change the inclination angle of the foliage cutting blade 312 many times, which may increase the labor spent by the operator. is there. Further, if the work is interrupted every time the angle changes, the work efficiency may be reduced.
For this reason, the following configuration is conceivable so that the inclination angle of the foliage cutting blade 312 is always substantially horizontal with respect to the farm scene.
As shown in FIG. 15 (a), the left and right end portions of the second relay transmission shaft 309 provided in the second cutting transmission case 305 are protruded to the left and right sides, that is, the right side of the machine body through the slide frame 313. The base portion of the weight arm 325 that is long in the vertical direction is provided on the protruding portion of the second relay transmission shaft 309. The weight arm 325 is configured to rotate together with the rotation of the cutting transmission gear case 310.
At the end of the weight arm 325, the cutting transmission gear case 310 and the weight arm 325 are rotated in conjunction with the inclination of the field, and the foliage cutting blade 312 is in a posture that is substantially horizontal with the field scene. A holding balance weight 326 is provided. The balance weight 326 is made of a material that can have a corresponding weight when made into a mass, such as a metal such as iron or a non-metal such as rubber.
With the above configuration, when the field where the onion pulling and harvesting operation is performed is inclined in the upward or downward direction, the rotatable cutting transmission gear case 310 and the weight arm 325 are rotated by the weight of the balance weight 326 and are balanced. Since the stable foliage cutting blade 312 stops at a position that is substantially horizontal with the field, the inclination of the foliage cutting blade 312 can be automatically adjusted to the inclination of the field, and the foliage is cut obliquely. It is prevented.
Thereby, the operation | work which removes the leaf and leaf part which was left uncut from an onion becomes unnecessary, and an operator's labor is reduced. Moreover, since the edible portion of the onion is cut by the foliage cutting blade 312 and can be prevented from becoming unsuitable for harvesting, a reduction in yield is prevented.
Further, when the inclination angle of the field is constant, the inclination angle of the foliage cutting blade 312 is kept constant by the balance weight 326, so that the cutting position of the foliage portion is prevented from varying, and the remaining foliage portion is removed. This improves the efficiency of picking up the onion that is grabbed and the drying work of hooking and hanging the uncut stems and leaves.
The balance weight 326 having the above-described structure has a different weight depending on the field. For example, a shaft in which a spiral hole is formed in the balance weight 326 and a screw groove formed in the lower end portion of the weight arm 325 is cut. If it is configured to be able to be screwed into the part, it can be easily changed to the balance weight 326 having a different weight, so that the work efficiency is improved and it is possible to adapt to a wide range of work conditions.
In addition, as shown in FIG.15 (b), the balance weight 326 of the said structure may insert a shaft part in each spiral hole, and may connect several, and may adjust a weight.
Alternatively, as shown in FIG. 16, the weight arm 325 may have a cylindrical shape, and the balance weight 326 may be suspended via a suspension member 326a or the like. The suspension member 6a has a wire or a synthetic resin rope on a loop and is wound around a hook portion (not shown) of the balance weight 326 or a balance weight 326 inside a bag made of a synthetic resin or a cloth material. Shall be stored. At this time, a plurality of balance weights 326 may be used, and the weight may be adjusted by increasing or decreasing the number.
However, when the balance weight 326 is provided with a mechanism for automatically adjusting the inclination angle of the foliage cutting blade 312 to an inclination angle suitable for a farm scene, the following problem may occur. For example, when the inclination angle of the foliage cutting blade 312 changes when passing through the unevenness of the field, the inclination angle of the foliage cutting blade 312 when cutting the foliage portion becomes an angle that is not suitable for cutting the foliage portion. May be cut diagonally, and the stems and leaves may remain in the edible portion of the onion, or the edible portion of the onion may be kicked with scratches.
Alternatively, when the aircraft is greatly tilted when turning at the heel end, the cutting transmission gear case 310 and the foliage cutting blade 312 rapidly rotate downward and hit the field scene, and the cutting performance of the foliage portion by the attached soil The cutting transmission gear case 310, the foliage cutting blade 312, and eventually the foliage cutting device 324 may be damaged.
In order to solve the above problem, it is necessary that the rotation speed of the cutting transmission gear case 310 is not interlocked even if the airframe angle changes suddenly, and the angle changes slowly.
Therefore, an L-shaped receiving rod 327 is provided between the left and right of the slide frame 313 and the weight arm 325, and a portion bent toward the left and right sides (right side of the body) of the lower portion of the receiving rod 327, The balance weight 326 or the weight arm 325 is connected by a restriction spring 328. The restriction spring 328 is mounted in a direction in which the balance weight 326 or the weight arm 325 is urged toward the receiving rod 327, and brakes the rotation of the weight arm 325 to be rotated by the weight of the balance weight 326. And The receiving rod 327 is configured to move up and down together with the cutting transmission gear case 310 and the weight arm 325 when the vertical position of the foliage cutting device 324 is changed by sliding the adjustment knob bolt 316 in the front-rear direction.
With the above configuration, even if the machine body is greatly inclined during the unevenness of the field or turning operation, the urging force of the restriction spring 328 restricts the rotation of the cutting transmission gear case 310 and the weight arm 325. The inclined posture of the blade 312 is less likely to change, and the foliage part is prevented from being left on the edible part of the onion and the edible part is prevented from being damaged.
In addition, since the cutting gear case 310 and the foliage cutting blade 312 can be prevented from colliding with the field scene, particularly at the heel end during the turning operation, the foliage part is not cut due to adhesion of soil, and the foliage cutting device 324 is prevented from being damaged. Is done.
Even if the regulating spring 328 is provided, the cutting transmission gear case 310 and the weight arm 325 rotate to the position corresponding to the weight of the balance weight 326, so that the inclination angle of the foliage cutting blade 312 is set to the inclination angle of the field. Since a suitable angle can be obtained, the cutting position of the foliage becomes more appropriate.
Further, as shown in FIG. 2, the right side (the left and right sides of the fuselage) shoulder-aligned driven pulley 46R is arranged at the front side of the fuselage with respect to the left side (the left and right sides of the fuselage) and the left and right upper shoulders. The alignment frames 44, 44 are each provided with a guide bar 52 for guiding the foliage on the left shoulder alignment driven pulley 46L side. Furthermore, the left shoulder-aligned driven pulley 46L is provided with a so-called star wheel having a protrusion, and the protrusions and leaves are guided to the left outer side of the machine body by this protrusion.
With the above configuration, after the cut foliage portion is released from the nipping state at the conveyance end portion of the shoulder aligner 51, the foliage portion is guided to the left side of the machine body by the left shoulder alignment belt 50 and the left and right guide bars 52, 52. Therefore, the discharge direction of the foliage part becomes constant, and the work at the time of collecting the foliage part from the field becomes easy.
Also, since the foliage is concentrated and discharged on the left side of the machine, it can be prevented that the foliage falls on the unharvested onion on the right side of the machine. This prevents the harvesting operation from being disturbed and improves the work efficiency.
Then, as shown in FIGS. 1 to 4, 17, and 18, longitudinal holes 44 a in the front-rear direction are formed on the rear sides of the left and right upper shoulder alignment frames 44, 44, respectively. A guide bevel gear case 330 that obtains driving force from the right shoulder alignment driven pulley 46R and transmits it to the rear of the machine body is mounted on the shoulder alignment frame 44 so as to be movable in the front-rear direction along the long hole 44a. A guide support frame 331 that is long in the up-down direction is disposed at a rear portion of the guide bevel gear case 330 and on the left and right sides (right side of the body) in an inclined posture toward the left and right sides toward the lower side of the body. The guide support frame 331 is provided so as to be rotatable in the front-rear direction of the machine body with an output shaft 330a protruding from the guide bevel gear case 330 as a fulcrum. It will rotate about 90 degree | times by side view to this posture. Within the range of 90 degrees, the guide support frame 331 can be set at any position by fixing members (not shown) such as bolts and nuts.
The long hole 44a is formed in the front-rear direction, but is formed to be slightly wider in the left-right direction than the diameter of the fixing member penetrating the long hole 44a, and can be moved in the left-right direction when the fixing member is loosened. The configuration.
A guide drive pulley 332 mounted on the output shaft 330a is disposed at the upper portion of the guide support frame 331 in the same inclined posture as the guide support frame 331, and a lower support shaft 333a is rotatable at the lower portion of the guide support frame 331. A guide driven pulley 333 to be mounted on is arranged. And the guide conveyance belt 334 which guides an onion to a field scene is wound around this guide drive pulley 332 and the guide driven pulley 333 in endless form. When the guide conveyance belt 334 has, for example, a round belt with no irregularities on the surface, the foliage is hardly caught, and the onion can be reliably discharged at the conveyance end portion.
Thereby, the guide device 335 which guides the onion discharged | emitted from the rear-end part of the shoulder alignment apparatus 51 toward a agricultural field, ie, a downward direction, is formed.
The conveyance start end portion, that is, the upper end portion of the guide device 335 faces the conveyance end portion of the shoulder aligning device 51, and after being cut by the foliage cutting device 324, a short foliage portion remaining on the onion is in contact with the arrangement configuration. Yes.
In addition, the cutting of the onion leaves and stems is performed not at the boundary between the stems and leaves and the edible portion, but at a position where some leaves and leaves remain in the edible portion. If the border between the foliage part and the edible part is cut, bacteria and viruses are likely to enter the edible part, and there is a risk that the part will rot. The problem of uncut leaves of the foliage is when the foliage above the foliage that needs to be left at least remains.
Further, a guide receiving plate 336 is provided on the lower surface of the left and right upper shoulder alignment frame 44 through a fixing member (not shown) so as to be movable in the front-rear direction along the elongated hole 44a. In 336, the bases of the front and rear foliage receiving rods 337f and 337r are arranged at intervals in the front-rear direction. The front and rear foliage receiving rods 337f and 337r are members in a plan view in which the base portion side is directed from the left and right other sides to the left and right sides, bent in the middle, and toward the rear of the body and downward.
The end portions of the front and rear foliage receiving rods 337f and 337r face the left and right sides of the guide device 335 so as to be in close contact with each other, and continue to the lower end of the guide device 335, which is the conveyance end portion.
Thereby, when the onion is discharged from the shoulder aligning device 51, the foliage portion of the onion is sandwiched between the guide device 335 and the foliage receiving rods 337f and 337r, and is guided to the vicinity of the farm scene and discharged.
With the above configuration, the onion discharged from the shoulder aligning device 51 can be guided to the lower side of the machine body by the guide device 335, so that the intervals of the onion discharged to the field can be easily aligned and The drying time is shortened when the onion is dried in the sun.
In addition, since the onion discharged later on the field is less likely to collide with the onion discharged later, the onion can be prevented from being damaged by the impact of contact, and the commercial value of the onion is improved.
Since the guide support frame 331 is provided so as to be pivotable in the front-rear direction, the inclination angle of the guide device 335 can be changed, so the distance from the lower end portion of the guide device 335 to the farm field and harvesting are performed. The onion guide conveyance can be terminated at an appropriate position according to the diameter of the edible portion of the onion (the size of the onion).
As a result, the fall distance to the field is long and the onion is damaged by the impact of the fall, or the distance to the field is short and the onion can be prevented from being damaged by being pushed into the field by the guide device 335. The product value of will improve.
In addition, the intervals between the onions discharged to the field are easily uniform, and the drying time is shortened when the onions are sun-dried on the field.
Further, when the guide device 335 is moved to a position that is substantially horizontal with the farm scene, a sufficient distance between the lower part of the machine body and the farm scene can be secured, so that the guide device 335 contacts the farm scene and is damaged. It is prevented.
The guide device 335 is provided in a posture that tilts downward toward the left and right sides, so that when the onion is discharged to the field, the stem and leaf portion and root portion of the onion are not easily in contact with the field scene, that is, the soil. Therefore, when the onion is dried in the sun in the field, it is prevented that bacteria and viruses in the soil enter from the cutting position of the foliage, and the onion is prevented from rotting and losing commercial value.
Furthermore, it is prevented that the root part touching the soil is regenerated and the nutrients are consumed to deteriorate the quality of the onion, and the onion is stretched in the soil and an onion that cannot be recovered during the recovery operation is prevented.
Further, the guide bevel gear case 330 that supplies driving force to the guide device 335 and the guide receiving plate 336 that supports the front and rear foliage receiving rods 337f and 337r are provided so as to be movable in the left and right directions, so that they remain uncut. Nipped and conveyed by the guide device 335 and the front and rear foliage receiving rods 337f and 337r according to the length of the foliage, the diameter of the edible portion of the onion (the size of the onion), or the distance between the end of the reed and the vegetation position of the onion Since the start position and the discharge position to the field can be adjusted, the intervals between the onions discharged to the field can be easily made uniform, and the time required for drying can be shortened and the effect of preventing damage can be improved.
In addition, since the onion discharged to the field can be prevented from falling into the trough groove, the left and right drive wheels 84L and 84R can prevent the onion from being reduced due to crushing the onion. Furthermore, since it is not necessary to move the onion from the gutter groove before the movement so that the left and right drive wheels 84L and 84R do not step on the onion, the time for the onion pulling and harvesting operation to be interrupted is shortened. The work efficiency is improved, and the labor required for the pick-up work is reduced.
Furthermore, since the left and right width of the long hole 44a is formed wider than the diameter of the fixing member that penetrates the long hole 44a, the guide bevel gear case 330 and the guide receiving plate 336 can be moved in the left and right direction. The onion discharge position can also be set in the front-rear direction, and can be adapted to various work conditions.
In addition, when the guide bevel gear case 330 and the guide receiving plate 336 are each attached with two fixing members, for example, when one fixing member is not loosened and the other fixing member is loosened, the guide bevel gear case 330 and the guide receiving plate 336 are loosened. Since the fixing member on the side not loosened can be rotated back and forth as a fulcrum, the onion discharge position can be changed more finely, and the configuration can cope with more various working conditions.
The guide bevel gear case 330 and the guide receiving plate 336 are configured to be switched between a movable state and a non-movable state by a fixing member (not shown) such as a bolt and a nut, and can be switched relatively easily. . However, since the front and rear foliage receiving rods 337f and 337r are disposed at substantially contacting positions on both the left and right sides of the guide device 335, both the guide device 335 and the front and rear foliage receiving rods 337f and 337r are movable left and right. It is necessary to.
In order to further reduce the time required for this work, if the guide receiving plate 336 is not provided with a fixing member and is slidable left and right, and the guide device 335 is moved and moved left and right, the front and rear foliage receiving rods 337f and 337r It is good also as a structure which moves to right and left interlockingly.
With this configuration, it is possible to adjust the discharge position of the onion to the field simply by making the guide bevel gear case 330 movable, thereby reducing the time required for the adjustment work and improving the work efficiency.
The onion discharged by the guide device 335 falls onto the vegetation that has been vegetated before harvesting and is collected after harvesting or after drying in the sun. However, since a normal onion is spherical, when it is discharged, the traveling device of a working machine such as a tractor that rolls on the cage and collects the left and right drive wheels 84L and 84R, the gauge wheel 73, and the onion is recovered. May fall into a passing groove. In addition, when a 3 or 4 onion is planted in one persimmon, when the 1st or 2nd onion is harvested, the discharged onion is the unharvested side, that is, the 3rd or 4th onion. May move to the vegetation side.
If an onion falls in the culvert groove, the worker needs to pick up the onion in the culm before collecting or collecting the onion, which reduces work efficiency and reduces the work efficiency. There is a problem that the labor of a person increases.
Then, the worker does not notice that the onion has fallen in the groin, and the right and left drive wheels 84L, 84R, the gauge wheel 73, or the traveling device of the work machine such as a tractor crushes the onion and loses the commercial value. Therefore, there is a problem that the yield is reduced.
In addition, if the onion rolls down on the unharvested side, the onion that rolls up on the side of the vertical pulling device 64, the horizontal pulling device 41, and the pulling and conveying device 19 prevents the foliage from being raised or pinched and pulled out. There is a problem in that the onion of the onion is generated and the operator needs to manually pull out the onion, which increases the labor of the operator.
Further, there is a problem that the vertical pulling device 64, the horizontal pulling device 41, and the pulling and conveying device 19 come into contact with the rolling onion, damaging the onion and reducing the commercial value.
In order to solve the above problem, as shown in FIGS. 1 and 4, support stays 130 are provided on the lower side of the body frame 1 and on the left and right sides of the left and right shoulder alignment belts 50 and 50, respectively. The left and right support stays 130 and 130 are each provided with an adjustment support plate 131 having a bent portion inclined downward toward the center of the conveying path of the shoulder aligner 51. The left and right adjustment support plates 131, 131 are formed with a long hole (not shown) in the left-right direction, and a mounting member such as a knob bolt 133 is provided in the long hole so as to be slidable when the holding force is loosened.
Furthermore, a first guide plate 134 that prevents the onion from rolling into the grooving groove is provided on the left side of the adjustment support plate 131 near the grooving groove through which the gauge wheel 73 and the driving wheel 84R pass through the knob bolt 133. Provide slidable in the left-right direction. When the first guide plate 134 is slid to the left along the adjustment support plate 131, the first guide plate 134 comes into contact with the upper surface of the ridge, and when the first guide plate 134 is slid to the right, the first guide plate 134 has a vertical length in which the lower side sinks into the soil.
On the other hand, a second guide plate 135 that prevents the onion that has been extracted and harvested from moving to the extraction and harvesting work position of the next process is placed on the adjustment support plate 131 on the right side near the center in the left-right direction of the basket through the knob bolt 133. And slidable in the left-right direction. When the second guide plate 135 is slid to the right along the adjustment support plate 131, the second guide plate 135 is spaced apart from the upper surface of the heel, and when slid to the left, the second guide plate 135 has a vertical length such that the lower side contacts the upper surface of the heel.
Then, in the front lower portions of the left and right first guide plates 134 and second guide plates 135, a first notch part 134c and a second notch part 135c that are inclined forwardly downward from the front side of the machine body to the rear side are formed in a side view. The front end portion of the second guide plate 135 forming the second notch portion 135c is formed on the rear side of the machine body from the front end portion of the first guide plate 134 forming the first notch portion 134c. If it is formed at a position about 100 to 150 mm, which corresponds to one onion, at the rear side position of the machine body, the second guide plate 135 does not prevent the onion from moving to the drawing and conveying area of the drawing and conveying device 19, and the onion is surely Pull-out harvesting is possible, improving work efficiency.
With the above configuration, the first guide plate 134 and the second guide plate 135 have a wider left-right distance in the front (rear) view, so that the two onions are located in the left-right direction at the narrowest left-right distance. When passing side by side, the gap is clogged and it is no longer moved to the rear of the machine body, so there is no need to interrupt the work and eliminate the clogging, and work efficiency is improved.
The left-right distance between the lower ends of the first guide plate 134 and the second guide plate 135 is preferably about 200 to 300 mm, which corresponds to two standard size onions.
Further, if the first guide plate 134 and the second guide plate 135 are each made of a material such as rubber that can be elastically deformed when a strong force is applied, the first guide plate 134 and the second guide plate 135 are less likely to be damaged and last longer.
With the above-described configuration, the onion where the cutting position is aligned by the shoulder aligning device 51, the foliage portion is cut by the foliage cutting blade 312, and discharged and guided onto the reed by the guide device 56 is the first guide plate 134 and the second guide. The plate 135 is placed on the basket that has been vegetated before the harvesting and has been harvested. As a result, the onion is prevented from rolling to the side where the trough or harvesting operation is not performed.
Therefore, it is not necessary to collect the onion that has fallen into the trough, and the next onion harvesting operation or the recovery of the onion on the reed can be performed when necessary. The labor spent by the person is reduced.
And since there is no onion in the culvert groove, the left and right drive wheels 84L and 84R, the gauge wheel 73, or the traveling device of the work machine such as a tractor does not step on the onion, and the yield of onion can be reduced. Is prevented.
In addition, since the onion can be prevented from rolling to the side where the harvesting operation is not performed, the onion drawing and harvesting operation of the onion by the vertical pulling device 64, the horizontal pulling device 41, and the pulling and conveying device 19 is not hindered. Will improve.
Furthermore, the vertical pulling device 64, the horizontal pulling device 41, and the pulling / conveying device 19 can be prevented from hitting or squeezing the rolling onion, so that the commercial value of the onion is maintained.
Since the first guide plate 134 has a vertical length that is such that the lower end is in contact with the heel, there is no gap for the small sized onion to move into the ridge, so that the onion may fall into the ridge. It is surely prevented.
Further, the front-rear length of the first guide plate 134 is set such that the rear end portion of the first guide plate 134 is positioned below the branch transmission case 6, so that the guide device 335 can be used even when the aircraft is traveling forward. The first guide plate 134 receives the onion that is discharged from the roll and rolls backward, so that it can be prevented from falling into the trough groove, eliminating the need for picking up the onion, reducing the labor of the operator, and improving the work efficiency. Therefore, it is possible to prevent the yield from decreasing.
Furthermore, by forming a bending guide portion 133a toward the left and right other side at the rear end portion of the first guide plate 134, and by setting the rear end portion of the second guide plate 134 to the upper side in the conveying direction of the guide device 56, When large onions are lined up, the onion can move laterally from the rear end of the second guide plate 134, so that the onion is clogged between the first guide plate 134 and the second guide plate 135. Is prevented.
Thereby, the onion is dragged and can be prevented from being damaged by the frictional resistance with the field scene, so that the commercial value of the onion is maintained.
In addition, since the onions discharged on the basket are less likely to be densely packed, the period required for drying is shortened because the ventilation and sunlight are improved when drying in the sun.
1 and 2, a second branch transmission case 6a is provided on the left and right sides of the branch transmission case 6, and the output shaft is raised from the front of the second branch transmission case 6a toward the front of the machine body. 58 is provided, and a bevel case 59a is mounted on the front end portion of the output shaft 58 that is raised and changes the driving force from the left and right other sides to the left and right sides. A pair of bevel gears (not shown) are housed inside the bevel case 59a, and the driving force of the pulling output shaft 58 in the output case is vertically lifted and transmitted to the transmission shaft 59 via the pair of bevel gears. To do. Then, the longitudinal pulling drive pulleys 60, 60, 60 are respectively mounted at the left and right one side ends, the left and right other side ends of the transmission shaft 59, and the substantially central portion in the left and right direction. The vertically raised covers 61, 61, 61 that cover the left and right sides of the 60, 60, 60 are mounted so as to be tilted rearward and rotated up and down. Further, the longitudinally driven covers 61, 61, 61 are respectively provided with longitudinally driven pulleys 62, 62, 62 at the lower ends thereof, and the longitudinally driven driving pulleys 60, 60, 60 are longitudinally driven and the driven pulleys 62, 62 , 62 is wound around the vertical elevating belts 63, 63, 63 provided with a plurality of vertical elevating lugs 63a... For causing the onions of the onion lying on the field to constitute the vertical elevating device 64.
It should be noted that the rearward tilt angle of the vertical pulling device 64 is substantially the same as the rearward tilt angle of the horizontal pulling device 41. As a result, the foliage portion caused by the vertical pulling device 64 is pulled up vertically and is laterally raised at the timing of separating from the lugs 63a, so that it is taken over by the horizontal pulling lugs 39a of the device 41. It can guide to 19 conveyance start end parts, and the improvement of the harvesting work efficiency of an onion is aimed at.

The right driving wheel 84R is prevented from being slightly displaced and the traveling direction of the machine body is disturbed, and the traveling performance and crop harvesting efficiency are prevented from being lowered.
Further, by setting the diameter of the mounting hole of the traveling transmission case 80R to be slightly larger than the diameter of the right transmission shaft 78R, when the right drive wheel 84R moves up and down due to unevenness in the field, the right transmission shaft Since 78R can move up and down and in the front-rear direction, the right transmission shaft 78R is prevented from being damaged by a load.
Further, by providing the fixed base mounting base of the adjustment cylinder 89 via the rotation pin 89a, the adjustment cylinder 89 can be moved to the right drive wheel even if the right drive wheel 84R moves up and down due to unevenness in the field. Since it moves up and down following the vertical movement of 84R, the adjustment cylinder 89 can be expanded and contracted when adjustment of the tread is necessary, and there is no need to change the vertical position of the right drive wheel 84R, thereby improving work efficiency. .
Further, since the right output shaft 78 and the sliding guide 90 are connected by the connecting plate 91, the right output shaft 78 and the sliding guide 90 slide in conjunction with each other, so that the right traveling transmission case 80R and the drive wheel 84R are connected. An inclined posture is prevented, an arbitrary tread can be set, and running performance is stabilized.
Further, since the hydraulic valve 92 is provided with a relief valve 92r that moves the hydraulic oil to the oil tank 92t to reduce the pressure, even if the tread adjusting lever 94 is erroneously operated while the traveling is stopped, When the pressure in the hydraulic valve 92 increases, the relief valve 92r returns the hydraulic oil to the oil tank 92t, and the expansion and contraction of the adjustment cylinder 89 can be stopped, so that the tread adjustment mechanism 95 is prevented from being damaged due to overload. The
If the right drive wheel 84R is slid to the side of the fuselage while traveling is stopped, a strong grounding resistance is generated, so that the adjustment cylinder 89 and the right output shaft 78 are overloaded, and the tread adjustment mechanism 95 is activated due to an erroneous operation or the like. Although there is a problem that it is damaged if it is not noticed, in this configuration, the expansion and contraction of the adjustment cylinder 89 automatically stops before an overload is applied, so that the occurrence of the problem is prevented.
When the adjustment cylinder 89 is extended to the maximum or contracted to the minimum, the tread adjustment lever 94 continues to be operated, and when an overload occurs, the hydraulic oil returns from the relief valve 92r to the oil tank 92t. Therefore, the expansion / contraction operation of the adjustment cylinder 89 is automatically terminated, and the tread adjustment mechanism 95 is prevented from being damaged.
Further, since the adjusting cylinder 89 and the oil feeding hose 93 in which the hydraulic oil moves are arranged in the groove portion 91u of the connecting plate 91, the oil feeding hose 93 can be removed simply by removing it from the adjusting cylinder 89. At times, the number of members to be attached and detached is reduced, and the maintainability is improved.
Since the tread adjustment lever 94 has a shape that bends rearward and upward, it is easier for the operator who performs the maneuvering operation behind the fuselage to operate the tread adjustment lever 94, thereby reducing the labor of the operator. In addition, the operability is improved.
Furthermore, by arranging the tread adjusting lever 94 at a position above the air cleaner 2p and away from the muffler in the left-right direction, the operator is not exposed to the high-temperature exhaust gas discharged from the muffler. Work comfort is improved.
Next, the structure regarding the leaf discharge guidance which guides the discharged foliage part, so-called leaf discharge, in the groin direction will be described.
As shown in FIGS. 9 and 10, a leaf cover 200 that covers the upper part of the branch transmission case 6 and the front and upper parts of the engine 2 and the transmission case 3 is provided in the lower rear part of the pulling and conveying device 19. The leaf cover 200 is provided along the inclined portions of the left and right handle support frames 7, 7, and the front end side of the leaf cover 200 is positioned on the front side of the body relative to the leaf guide action area of the leaf guide plate 20. Arrange as follows.
Then, at the left end of the body of the leaf cover 200, the leaf and leaf portion guided by the leaf guide plate 20 and the left pulling and conveying belt 17 is more specifically outside the left side of the body. A base side of the leaf shooter 201 that guides and discharges between the traveling transmission case 80L and the left drive wheel 84L is detachably provided. The leaflet shooter 201 protrudes to the left outer side of the machine body and then bends toward the lower side of the machine body so as to cover the upper part of the left traveling transmission case 80L and the outer part of the machine body.
At this time, as shown in FIG. 9, the lower end portion of the leaflet shooter 201 is located above the axle 83 in the left traveling transmission case 80L, and at this position, an elastic connection such as a spring or a rubber band is provided. It is attached to the left traveling transmission case 80L via the member 203. At this time, the elastic connecting member 203 biases the leaf shooter 201 downward, and always holds the leaf shooter 201 in a stretched state.
When the leaf shooter 201 is attached to the leaf cover 200, if the leaf leaf shooter 201 is positioned below the leaf cover 200, the stems and leaves that are guided to be discharged are separated from the leaf cover 200. Since it becomes difficult to get caught between the leaf shooters 201, the leaf removal operation can be performed efficiently.
When the above described leaf shooter 201 is made of a soft synthetic resin having a soft surface such as polyvinyl chloride, the leaf shooter 201 can be prevented from being caught during the discharge guidance of the foliage portion, and the left drive wheel 84L and the traveling transmission case 80L can be prevented. It becomes easy to arrange it to fit between the left and right. In addition, when the traveling transmission case 80L is rotated up and down, the lower end portion of the leaf transmission shooter 201 moves in the vertical direction in conjunction with the vertical rotation of the traveling transmission case 80L. In addition, the leaflet shooter 201 is prevented from being damaged.
Further, the covering range on the base side of the leaf discharging shooter 201 is set to the inner side of the machine body from the leaf leaf conveying action area of the leaf discharging guide plate 20 and to the front side of the left traveling transmission case 80L. In addition to this, the front end side of the defoliation shooter 201 is inclined from the outside of the body toward the inside of the body, and the fall position of the foliage portion on the field is set to the side closer to the inside of the body than the traveling position of the left driving wheel 84L. In the groove.
Furthermore, as shown in FIGS. 9 and 10, a wheel having the same diameter as the left driving wheel 84L or a small diameter wheel that restricts the movement of the foliage part to the left driving wheel 84L inside the left driving wheel 84L. A cover 202 is detachably provided. The wheel cover 202 is mounted on the axle 83 and arranged to rotate with the left drive wheel 84L, and the lateral width increases from the outer peripheral edge toward the axle 83. At this time, a slope is formed on the wheel cover 202 in plan view and front back view.
The leaf cover 200 and the wheel cover 202 are made of a highly corrosion-resistant material such as a stainless steel material or a synthetic resin so as to prevent corrosion caused by water adhering to the foliage part or juice resulting from scratches on the foliage part. If the surface of the metal plate is coated with a material having strong anticorrosion properties such as rubber or synthetic resin, the durability is improved.
With the above configuration, the foliage portion is placed on the foliage cover 200 even if the foliage portion discharged from the pulling and conveying device 19 is not guided to be discharged to the left side of the machine body by the foliage guide plate 20. The discharged foliage is prevented from being caught in various parts of the machine body, and the time and labor required for removing the foliage are reduced.
Further, the leaflet shooter 201 is provided at the left end of the body of the leaflet cover 200, and the lower end portion of the leaflet shooter 201 faces the left and right of the left traveling transmission case 80L and the drive wheel 84L. Can be guided to the trough, so that the discharged foliage is prevented from interfering with the pinching of unharvested onion, and the onion is prevented from being left in the field. Reduces the time and effort of pulling and harvesting.
Alternatively, since the foliage can be prevented from getting on the onion that has been left on the straw for drying after the drawing harvest, the time for the onion to dry by the sun or wind is shortened.
Then, when the leaflet shooter 201 covers the inside of the machine body from the leaflet conveyance action area of the leaflet guide plate 20, when the foliage portion guided by the left pulling conveyance belt 17 and the leaflet guide plate 20 falls. Even so, it can be taken over by the leaflet shooter 201, so that the leaves and leaves are prevented from remaining on the machine body, and the time and labor required for the removal work are reduced.
Furthermore, since the leaflet shooter 201 covers the upper side of the left traveling transmission case 80L and the outside of the fuselage, it is possible to prevent the foliage from getting tangled with the left traveling transmission case 80L, particularly the axle 83. This eliminates the need to improve work efficiency and reduce labor.
Further, the lower leaflet shooter 201 and the left traveling transmission case 80L are connected by the elastic connecting member 203, and the leaflet shooter 201 is biased downward, so that the leaflet shooter 201 is drowned or slackened by wind or the like. By doing so, it is possible to prevent the space part into which the foliage part enters, so that the fouling of the foliage part is prevented, and the work efficiency is improved and the labor is reduced.
Since the wheel cover 202 is provided inside the fuselage of the left drive wheel 84L, the foliage discharged from the leaflet shooter 201 can be prevented from coming into contact with the left drive wheel 84L and entangled. Occurrence of entanglement is prevented, improving work efficiency and reducing labor.
In addition, the thickness of the wheel cover 202 increases as it gets closer to the axle 83, so that even if the foliage is entangled with the wheel cover 202, the foliage is likely to come off due to a change in diameter, and the foliage is removed. Less labor is required.
Further, the front end side of the leaflet shooter 201 is inclined from the outside of the body toward the inside of the body, and the foliage can be discharged to a position that is difficult to be stepped on the left driving wheel 84L in the ridge groove. The wheel 84L is prevented from slipping by stepping on the foliage, and the running posture and the onion pulling and harvesting posture are stabilized.
Hereinafter, another configuration example of the onion harvester will be described.
As shown in FIG. 19, front and rear holding guide frames 338f and 338r are provided on the guide receiving plate 336 in a posture from the left and right other side (left side of the machine body) to the left and right side (right side of the machine body) in plan view. The rear end portions of the guide frames 338f and 338r are made to face both right and left immediately before the guide device 335. Further, sandwiching guide drive pulleys 339 and 339 are respectively provided on the front side and the upper side of the holding guide frames 338f and 338r, and the first left and right first holding guide driven pulleys 340 are provided on the front side and the lower side of the holding guide frames 338f and 338r. 340, respectively, and left and right second clamping guide driven pulleys 341, 341 are provided on the rear side of the holding guide frames 338f, 338r and on the upper side, respectively, and on the rear side of the holding guide frames 338f, 338r and on the lower side The third clamping guide driven pulleys 342 and 342 are respectively provided.
More specifically, the sandwiching guide drive pulleys 339 and 339, the first sandwiching guide driven pulleys 340 and 340, the second sandwiching guide driven pulleys 341 and 341, and the third sandwiching guide driven pulleys 342 and 342 are unequal sides. The image-shaped holding guide frames 338f and 338r are arranged at the four corners.
The clamping guide belts 343 and 343 are arranged across the clamping guide driving pulleys 339 and 339, the first clamping guide driven pulleys 340 and 340, the second clamping guide driven pulleys 341 and 341, and the third clamping guide driven pulleys 342 and 342. Each is wound endlessly. Further, a clamping guide transmission motor 344 for supplying a driving force is provided in the vicinity of one of the left and right clamping guide driving pulleys 339 and 339. The left and right clamping guide drive pulleys 339 and 339 are mounted on the output shaft of the clamping guide electric motor 344, respectively. In this way, a sandwiching guide device 345 is configured which sandwiches the stems and leaves that are left uncut from the onion together with the guide device 335 and guides it to the field.
The clamping guide drive pulleys 339 and 339 and the first clamping guide driven pulleys 340 and 340, the second clamping guide driven pulleys 341 and 341, and the third clamping guide driven pulleys 342 and 342 are close to the diameter of a standard onion. , And spaced about 200 mm apart.
This prevents the onion from being clogged between the clamping guide driving pulleys 339 and 339 and the first clamping guide driven pulleys 340 and 340, the second clamping guide driven pulleys 341 and 341, and the third clamping guide driven pulleys 342 and 342. Therefore, the harvesting operation is not interrupted, and the work efficiency is improved.
In addition, if the left and right sandwiching guide belts 343 and 343 are configured with, for example, round belts with no irregularities on the surface, the foliage is less likely to be caught, and the onion is held at the sandwiching and conveying end portions of the guiding device 335 and the sandwiching guide device 345. Since it can be reliably discharged to the field, the onion is not discharged to the field, and the work is prevented from being interrupted by the removing operation.
With the above configuration, since both the guide device 335 and the sandwiching guide device 345 are driven, the onion sandwiching the foliage portion can be reliably and smoothly guided toward the field scene, so that the foliage portion is clogged and the guide device. The onion guidance by 335 is prevented from being interrupted, and the work efficiency is prevented from being lowered.
In addition, since the onion speed is reduced and the distance between the onion and the subsequent onion can be prevented from being narrowed, the distance between the front and back of the onion discharged to the field is substantially constant, and the time required for sun drying of the onion is reduced. Shortening is achieved.
Further, by providing the guide receiving plate 336 with the holding guide frames 338f and 338r of the holding guide device 345, when the guide receiving plate 336 is moved left and right by loosening the fixing member, the left and right positions of the holding guide device 345 can be easily moved. Since the time required for the adjustment work can be shortened, the work efficiency can be improved.
In addition, when the fixing member of the guide receiving plate 336 is excluded and the sandwiching guide device 345 moves left and right in conjunction with the left and right movement of the guide device 335, an operation of switching the sandwiching guide device 345 to be movable left and right is unnecessary. Work efficiency is improved.
Even when the holding guide device 345 is provided, the guide receiving plate 336 can be moved back and forth when the fixing member is loosened, and by rotating only one of the fixing members, the guide receiving plate 336 can be rotated about the other fixing member. It is set as the structure which can do.
In addition, the foliage is supported at three points by sandwiching the foliage with the three belts of the guide conveyance belt 334 and the right and left clamping guide belts 343 and 343, so that the foliage comes off during the conveyance and the onion falls. It is prevented that the onion is damaged by the impact of the fall and the commercial value is reduced, and the interval between the onions is prevented from being disturbed, and the time required for sun drying is shortened.
Next, a configuration for easily adjusting the left and right positions of the guide device 335 and the front and rear foliage receiving rods 337f and 337r or the holding guide device 345 will be described.
As shown in FIG. 20, a sliding shaft 346 that is long in the left-right direction is provided on the left and right upper shoulder alignment frame 44 to slide the guide bevel gear case 330 in the left-right direction, and the sliding shaft 346 is rotated. A position adjusting handle 347 for changing the left and right position of the guide bevel gear case 330 is provided. Specifically, a hole portion (not shown) having a screw groove formed inside is formed outside the guide bevel gear case 330, and a sliding shaft 346 having a screw groove formed on the outer peripheral portion is passed through the hole portion. When the slide shaft 346 is rotated by the operation of the position adjusting handle 347, the guide bevel gear case 330 moves in the left-right direction of the machine body.
With the above configuration, the operator can move to the shoulder aligner 51 and operate the position adjustment handle 347 while standing at the rear of the machine body without performing the operation of loosening the fixing member. It is possible to easily adjust the discharge position of the onion by adjusting the left and right positions, improving the work efficiency.
In the case of the above configuration, if the front and rear foliage receiving rods 337f and 337r or the holding guide device 345 are always movable in the left-right direction, no operation other than the position adjustment handle 347 is required, and more. Work efficiency is improved.
In order to further save labor, as shown in FIG. 21, an electric cylinder 348 is provided on the side of the guide bevel gear case 330, and a position adjustment dial 349 is provided in the vicinity of the handle 8 shown in FIG. It is good also as a structure which moves the guide bevel gear case 330 to the left-right direction by expansion / contraction of 348, and changes the discharge position of an onion.
Alternatively, as shown in FIG. 22, the guide bevel gear case 330 may be provided with a left-right rack gear 350 and an electric motor 351 provided with a pinion gear 351 a contacting the rack gear 350. The electric motor 351 is operated by the position adjustment dial 349.
In the above configuration, the position adjustment dial 349 provided at the rear part of the machine body is operated to operate the electric cylinder 348 and the electric motor 351 so that the discharge position of the onion can be adjusted left and right. Can be reduced.
Further, since the fine position adjustment is possible, it is possible to secure the interval between the onions and prevent the onions from falling into the eaves groove.
Next, a description will be given of a configuration in which the onion discharge position of the guide device 335 can be changed in accordance with wind and rain, onion growth, and pulling and harvesting.
The edge of the reed is easily affected by wind and rain and may have collapsed during harvesting. Also, when the onion grows into a spherical shape, the surrounding soil is pushed away by that amount, but the end of the heel may collapse due to the influence. Furthermore, since the surrounding soil is pushed away even when the onion of the heel is pulled out of the field, the edge of the heel may collapse at this time.
If the onion is discharged onto the ridge in this state, the onion is likely to roll down in the ridge groove, so that the left and right drive wheels 84L and 84R crush the onion, resulting in a problem of reducing the yield. In order to prevent the occurrence of this problem, it is possible to pick up the crop that has fallen in the trough, but at that time the harvesting work must be interrupted and the worker must perform it manually, which reduces work efficiency. In addition, there is a problem that the labor consumed by the worker increases.
In order to prevent this problem, as shown in FIGS. 23 and 24, the state of the heel end is detected at the lower part of the left and right other side (left side of the body) of the body frame 1 and outside the body of the first guide plate 134. Specifically, the heel photographing device 352 (CCD camera) that is determined by photographing is arranged in a posture in which the photographing range becomes a farm scene below the machine body. The heel imaging device 352 may be configured to change the lens or the like so that the imaging range becomes wider.
Further, the gutter groove photographing device 352 is arranged on the front side of the machine body from the discharge position of the onion from the guide device 335 and below the foliage cutting device 324.
If the heel end photographing device 352 is disposed at a position where the upper part is completely covered by the leaf shooter 201, the discharged foliage part covers the heel end and prevents the state of the heel from being detected. The detection accuracy of the state is improved.
The video imaged by the grooving device 352 is displayed on a monitor panel 353 provided on the handle 8, and the operator confirms the state of the heel while viewing this video. When it is determined that the tip of the heel has collapsed and the current onion discharge position to the field is highly likely to drop into the ridge, the operator operates the position adjustment handle 347 or the position adjustment dial 349. Then, the onion discharge position by the guide device 335 or the like is switched to a position closer to the center in the left-right direction of the basket.
With the above configuration, it is possible to confirm that the heel end has collapsed before discharging the onion, and the onion can be discharged to a position away from the end of the culm. In addition, the work of picking up the onion from the trough is not necessary, and the work efficiency is improved.
In addition, when the operator recognizes the collapse of the heel before passing through the left and right drive wheels 84L and 84R, the operator operates the tread adjusting lever 94 in accordance with the collapse of the heel and moves the left and right drive wheels 84L and 84R. Since the tread can be adjusted, one of the left and right drive wheels 84L and 84R rides on the broken soil and the aircraft tilts left and right, leaving the onion in the field and disturbing the cutting position of the foliage Can be prevented.
Alternatively, the left and right drive wheels 84L and 84R can be prevented from moving away from the basket and the traveling direction slightly deviating from straight, so that the onion can be reliably pulled out from the field and the remaining onion can be harvested manually. The work to do becomes unnecessary.
Further, by providing the heel end photographing device 352 on the outer side of the machine body with respect to the first guide plate 134, the heel end photographing device 352 does not come into contact with the onion being transported, and the onion is damaged and the commercial value is reduced. In addition, it is possible to reliably detect the state of the heel end and to appropriately adjust the discharge position of the onion.
Furthermore, the onion photographing device 352 is arranged on the front side of the fuselage from the discharge position of the onion from the guide device 335 and below the foliage cutting device 324, so that the onion whose foliage has been cut by the foliage cutting device 324 can be obtained. In addition, since the operator can grasp the state of the heel end where the shoulder can be dropped from the shoulder aligning device 51 or the guide device 335, the onion is less likely to fall into the culvert groove, and the yield of onion is maintained. In addition, work efficiency can be improved.
Note that the state of the heel captured by the heel imaging device 352 is determined by, for example, pixels, and when it is determined that the heel is broken, the electric cylinder 348 and the electric motor 351 are automatically operated, and the onion is turned on. It is good also as a structure from which the discharge position of this is near the center part of the left-right direction of a bag.
Next, a mechanism for changing the left and right positions of the guide device 335 and the front and rear foliage receiving rods 337f and 337r or the holding guide device 345 according to another configuration will be described.
As shown in FIGS. 25 (a) to 25 (c) and FIG. 26, left and right rotational support shafts 44s and 44s are provided in the vicinity of the center in the front-rear direction of the left and right upper shoulder alignment frames 44 and 44, respectively. The left and right second shoulder alignment frames 44f and 44f are arranged so as to be rotatable in the left-right direction of the body, respectively, on the rotation support shafts 44s and 44s and on the upper portions of the left and right upper shoulder alignment frames 44 and 44. Shoulder alignment tension arms 44t and 44t having a pair of front and rear shoulder alignment tension rollers 44r and 44r are fixed between the left and right second shoulder alignment frames 44f and 44f and the upper and lower upper shoulder alignment frames 44 and 44, respectively. The left and right shoulder alignment belts 50, 50 are pressed from the inside of the winding area toward the outside.
The left and right shoulder-aligned driven pulleys 46L and 46R are provided at the rear portions of the left and right second shoulder-aligned frames 44f and 44f, and the left and right guide bars 52, 46R are provided on the front side of the left and right shoulder-aligned driven pulleys 46L and 46R. 52 bases are provided. Further, the guide bevel gear case 330 is provided on the upper side of the right shoulder-aligned driven pulley 46R toward the rear side of the machine body, and a guide device 335 is attached to the guide bevel gear case 330, and from the left shoulder-aligned driven pulley 46L. Also, a guide receiving plate 336 provided with the front and rear foliage receiving rods 337f and 337r or the holding guide device 345 is provided on the front side of the body and on the front side of the left side of the guide bar 52.
Also, connecting arms 354 and 354 are provided respectively from the left and right second shoulder alignment frames 44f and 44f toward the rear side of the machine body, and the left and right connecting arms 354 and 354 are provided on the front side of the leaflet cover 200 in the left-right direction. It connects with the slide mechanism 355 provided.
The slide mechanism 355 is a cylinder or a prism having a hole (not shown) formed with a screw groove inside, and a slide shaft 355a having a screw groove formed on the outer periphery thereof is rotatably inserted into the hole. The rear end portions of the left and right connecting arms 354 and 354 are mounted on the sliding shaft 355a. Further, a sliding electric motor 356 that rotates the sliding shaft 355a is provided at one end of the sliding shaft 355a on the left and right sides (right side of the machine body). When the sliding electric motor 356 is driven to rotate, the sliding 355a Rotates clockwise or counterclockwise to rotate the left and right second shoulder alignment frames 44f and 44f connected by the left and right connecting arms 354 and 354 in the left and right direction of the body. The sliding electric motor 356 is operated by operating the position adjustment dial 349.
In addition, by operating the sliding electric motor 356 in accordance with the state of the heel imaged by the heel image capturing device 352, the left and right second shoulder alignment frames 44f and 44f are rotated in the left and right direction. The onion discharge position of the guide device 335 and the front and rear foliage receiving rods 337f and 337r or the holding guide device 345 may be automatically adjusted.
With the above-described configuration, when the slide mechanism 355 is operated, the left and right second shoulder alignment frames 44f and 44f are rotated in the left-right direction, whereby the conveying path of the shoulder alignment device 51, the guide device 335, and the front and rear foliage receiving rods 337f. , 337r, or the holding guide device 345, the discharge guide position of the onion can be changed at the same time, so that the foliage portion left uncut by the guide device 335 and the front and rear foliage receiving rods 337f, 337r, or the holding guide device 345. Can be reliably clamped, and the onion is prevented from falling onto the field during the takeover.
Thereby, since the front-and-rear spacing between the onions is sufficiently ensured, the drying time is shortened when the onions are sun-dried in the field.
In addition, since the onion discharged later on the field is less likely to collide with the onion discharged later, the onion can be prevented from being damaged by the impact of contact, and the commercial value of the onion is improved.
And since it was set as the structure which rotates the sliding shaft 355a with the sliding electric motor 356, while being able to reduce the effort which an operator spends, the movement amount of the sliding shaft 355a can be adjusted finely, Adjusting the discharge position of onions to the field becomes more appropriate.
Further, the sliding electric motor 356 is operated in accordance with the state of the heel photographed by the heel end photographing device 352, so that the discharge guide position of the onion is set to the center side of the heel when the heel end is collapsed. Since the discharge guide position can be automatically returned to the heel end side after passing through the collapsed portion, the onion is prevented from falling into the ridge groove.
This prevents the left and right drive wheels 84L and 84R from crushing the onion and reducing the amount of onion harvest. Furthermore, since it is not necessary to move the onion from the gutter groove before the movement so that the left and right drive wheels 84L and 84R do not step on the onion, the time for the onion pulling and harvesting operation to be interrupted is shortened. The work efficiency is improved, and the labor required for the pick-up work is reduced.
Further, since it is not necessary for the operator to frequently operate the slide mechanism 355, work efficiency can be improved.
