The root part of the cut carrot (I) falls downward, and the foliage part is conveyed to the rear side of the body by the leaflet belts 32 and 32 and discharged from the rear side of the body.

  On the front side of the left and right nipping and conveying belts 9L and 9R, lugs 34a and 35a projecting in the front-rear direction and the left and right direction are respectively circulated so that the foliage is pinched appropriately by the belts 9L and 9R. A vertical pulling device 34 and a horizontal pulling device 35 are provided. The carrot (I) conveyed on the machine body by the harvesting unit 4 is conveyed by the conveyance unit 6 toward the opposite side to the side where the harvesting unit 4 is arranged (from the left side of the machine body to the right side) and accommodated. It is accommodated in a container C which is a container placed in the section 5.

  The transport unit 6 is located below the cutting device 31 and is positioned so as to be parallel to the front side of the first conveyor 36 and the first conveyor 36 that transports carrots (I) in the left-right inner direction of the machine body. A second conveyor 37 that transfers the carrot (I) in the same direction as the transfer direction of the conveyor 36, and a second conveyor 37 that extends from the transfer end of the second conveyor 37 toward the rear of the machine and transfers the carrot (I) in the same direction. The configuration includes three conveyors 38.

  The carrots (I) that have been transported by the harvesting unit 4 and cut and fallen by the cutting device 31 are received on the first conveyor 36 and then transferred to the left and right inner sides of the machine body. Further, it is transferred in the same direction (right side of the machine body) by the second conveyor 37, and then transferred toward the rear of the machine body by the third conveyor 38, and is arranged behind the transfer end portion of the third conveyor 38. It is discharged into the container C placed in the storage unit 5.

  The first conveyor 36 is a belt conveyor having a flat surface, and a remaining leaf processing roller 39 whose lower side is driven and rotated in the same direction as the belt rotation direction on the upper surface of the belt on the lower transfer side is provided with the roller 39. It is arrange | positioned with the inclination attitude | position by the body planar view with respect to the transfer direction.

  In the present embodiment, the end of the remaining leaf processing roller 39 on the lower side in the transfer direction is disposed on the side closer to the second conveyor 37. Accordingly, when the carrot (I) is transferred by the first conveyor 36 and hits the remaining leaf processing roller 39, it is discharged onto the second conveyor 37 arranged on the front side of the first conveyor 36, but the cutting device 31. The leaves (residual leaves) extending from the base of the stems and leaves remaining on the root side of the carrot (I) after being cut by the gap between the upper surface of the belt 36a of the first conveyor 36 and the residual leaf processing roller 39 It is pulled in and discharged in the direction of arrow R (FIG. 2) and removed.

  First, the root vegetable harvesting machine 1 starts the engine 64, and at the start of the above-described harvesting operation, the operator lowers the grounding wheel 15 that is pivoted in front of the crawler 8L on the side of the soiler 11 to perform grounding. And start work. Carrot (I) harvesting work is carried out while driving the rotating parts of the machine body and setting the digging height (drawing position) of the holding and conveying device 9 in advance, and transmitting the crawlers 8L and 8R to advance the vehicle body in the field. Start.

  In this case, since the soiler 11 is connected to the holding and conveying device 9 by the connecting pipe 73 at the fulcrum portion 75a provided on the mounting member 75, the soiler 11 descends integrally and the tip portion sinks into the soil (see FIG. 1). It will be.

  Subsequently, the soira 11 advances in the soil as the root vegetable harvesting machine 1 advances, and at its tip end, the carrot (I) is pushed up from the bottom to the ground, and the vertical pulling device 34 and the horizontal pulling device 35 are used to carrot ( The stems and leaves of (a) are raised, and the start ends of the sandwiching and conveying belts 9L and 9R pinch the carrot (ii) and pull it up and convey it.

  Then, when the foliage belts 32 and 32 are handed over to the foliage belts 32, the cutting device 31 cuts the base of the foliage of carrot (I), and the root of the cut carrot (I) falls downward. The foliage is conveyed to the rear of the machine by the leaflet belts 32 and 32 and discharged from the rear of the machine.

The carrot (A) that has fallen after the foliage is cut by the cutting device 31 is received on the first conveyor 36, transferred to the left and right inner sides of the machine body, discharged onto the second conveyor 37, and It is transferred in the same direction (right side of the machine body) by the two conveyors 37, and then transferred toward the rear of the machine body by the third conveyor 38, and placed on the storage unit 5 disposed behind the transfer terminal end of the third conveyor 38. It is discharged into the container C.
The harvesting operation is continued as described above. When the container C from which the carrot (I) is harvested becomes full, the empty container C is replaced and the carrot (I) is continuously harvested.

  In such a series of harvesting operations, the operation of raising and digging roots and leaves of the root vegetables is performed first, and the subsequent operation is influenced by how efficiently this operation is performed. The efficiency of a series of harvesting operations also depends on how to prevent the soil adhering to the root vegetables when digging the root vegetables.

  Therefore, according to the present embodiment, as shown in FIG. 3, the farm field passes below the carrots (I) below the nipping and conveying belts 9 </ b> L and 9 </ b> R that are nipping and conveying operation portions of the pulling and conveying apparatus 9. It is characterized in that a soiler 11 in which the front end U is located below the lowest position T (dotted line portion) of the carrot (a) is provided. By adopting this configuration, the carrot (I) can be pushed up and dug by the soyler 11, so that mud can be prevented from adhering to the root vegetables, and the efficiency of the harvesting work is improved.

  In the case of clay farms, etc., if a vibrating soya that uses vibration to loosen the surrounding soil is used, the soil will harden, making it difficult to extract the root vegetables. However, by adopting this configuration, regardless of the state of the field, when harvesting root vegetables from a clay field, or when harvesting root vegetables from a field where stem grass has withered and weakened in winter. In particular, such a case is suitable because it can prevent mud from adhering to the root vegetables and can efficiently dig up the root vegetables.

  And as shown in FIG.3 (b), the wide plate 11a exists in the circumference | surroundings of a carrot (I) by providing the wide plate 11a in the front-end part of the soiler 11 below the front-end | tip of the clamping conveyance belts 9L and 9R. Since the soil can be lifted wider than when only the soira 11 is used, the carrot (I) can be reliably pushed up to the ground, and the carrot (I) in the field can be raised. Further, if the width of the front end portion of the wide plate 11a is gradually narrowed to have a triangular shape in plan view, the front end portion of the soiler 11 can easily enter the soil, so that the resistance when the soiler 11 sinks into the soil is reduced. Can be small.

  Further, the wide plate 11a is fixed to the soiler 11, and the soy 11 is passed through the soil from directly under the carrot (b), so that the wide plate 11a is less likely to contact the carrot (b). ) Can be prevented from being damaged, and the commercial value of carrot (I) is improved.

  As shown in FIG. 3, the wide plate 11a is attached and fixed to the main body of the soiler 11 with bolts 70 or the like. A plurality of holes for attaching the bolts 70 are provided in the body of the soiler 11, and the holes for attaching the bolts 70 can be selected. Therefore, according to FIG. 3, it is the structure which can adjust the position of the wide plate 11a by the width W to the front-back direction suitably. Thus, field adaptability improves by adjusting the position of the wide plate 11a according to the state of a field.

  Furthermore, the width w1 of the wide plate 11a is preferably wider than the width w2 of the soiler 11, and narrower than the left and right width w3 of the front end portion of the drawing and conveying apparatus 9. By making the width w1 of the wide plate 11a wider than the width w2 of the soiler 11, the root vegetables can be pushed up and dug more reliably, so the efficiency of the harvesting operation is improved. In addition, when the width w1 of the wide plate 11a is made wider than the left and right width w3 of the front end portion of the pulling and conveying apparatus 9, the wide plate 11a may hit the carrot (I) on the adjacent strip and be damaged. However, since the width w1 of the wide plate 11a is narrower than the left and right width w3 of the front end portion of the pulling and conveying device 9 as in this configuration, it is possible to prevent the adjacent carrots (I) from being damaged. Value is improved.

FIG. 4 (a) shows an enlarged side view of the main part in the vicinity of the soiler 11 of another embodiment of the root vegetable harvesting machine, and FIG. 4 (b) shows a front view of FIG. 4 (a).
As shown in FIG. 4, left and right plates 11d and 11d are provided at the tip of the soiler 11, and a space is provided between the left and right plates 11d and 11d. Incidentally, the left and right plate 11d, 11d are attached, et al. In each welded to the left and right upper surface of the member 27 that is bolted to the hole of the tip of Soira 11. The member 27 can adjust the mounting position at the tip of the soiler 11. Therefore, although the left and right plates 11d and 11d cannot slide, the position of the front and rear direction can be adjusted integrally with the member 27.

  With such a shape, even when the lower part of the carrot (I) is substantially the same height as the left and right plates 11d, 11d or above the left and right plates 11d, 11d, the lower part of the carrot (I) is left and right plates 11d, 11d. Since it can pass between, carrot (I) becomes hard to be damaged and the efficiency of harvesting work improves.

FIG. 5 (a) shows an enlarged side view of the main part in the vicinity of the soiler 11 of another embodiment of the root vegetable harvesting machine, and FIG. 5 (b) shows a front view of FIG. 5 (a).
Further, as shown in FIG. 5, the position of the body of the soiler 11 may be moved to either the left or right side of the center position in the left-right direction (width direction) of the pulling and conveying device 9. FIG. 5 shows an example in which the center position of the main body of the soiler 11 is moved to the right side, but it may be moved to the left side. Since carrots (I) are dug up near the center of the wide plate 11a, the adoption of this configuration prevents the carrots (I) from interfering with the main body portion of the soiler 11, thereby preventing carrots (I) from being damaged. it can.

  Further, as shown in FIG. 5, the upper end portion of the soiler 11 is supported by the drawing conveyance frame 25 by a support member 77. And the attachment position to the drawing conveyance frame 25 of the upper end part of the soiler 11 can be changed by providing several bolt holes in this connection part. FIG. 5 shows an example in which the attachment position to the drawing / conveying frame 25 can be adjusted in three stages, upper and lower, but it may be two stages in the upper and lower stages, and the vertical width of the soiler 11 and the support member 77 may be widened to increase the number. It is good also as a structure which can be adjusted to a step.

  Thus, by adopting a configuration in which the vertical height changes in the arrow V direction around the fulcrum portion 75a by changing the mounting position of the upper end portion of the soiler 11, the vertical direction of the lower end portion of the soiler 11 is changed. Since the height can be adjusted, it can be changed by the length of the crop. In other words, the adjustment is made so that it is deeper for long crops and shallower for short crops. Although the length of the crop is not necessarily constant, since the average length is roughly determined for each variety, it can be adjusted accordingly and the field adaptability of the root crop harvester is improved.

  Further, as shown in FIGS. 3 and 5, the upper end portion of the soiler 11 attached to the body frame 17 is at a position higher than the fulcrum 75 a, so that it is easy to adjust the attachment position of the soiler 11 with respect to the body frame 17.

  And if it is set as the structure which attaches the root hair removal apparatus 10 on the support member 77 in the connection part with the drawing | extracting conveyance frame 25 at the upper end part of the soiler 11, as shown in FIG. There is no need to provide it, and the cost can be reduced by eliminating extra members.

  Moreover, it is good also as a structure which bladed the action surface (The part which contacts the ground and digs up the soil) with the ground (farm field) of the wide plate 11a shown in FIG. For example, the periphery (shaded portion) of the triangular portion at the tip of the wide plate 11a shown in FIG. Thus, by cutting the working side of the wide plate 11a with the ground, when the wide plate 11a sinks into the soil, the soil is cut, and the resistance of the soil is reduced. The excavation work can be performed smoothly.

  Further, as shown in a perspective view of the wide plate 11a portion of the soiler 11 in FIG. 6, if the fold is made along the horizontal center line of the wide plate 11a to be inclined, and it is V-shaped in front view, Since the front end of the wide plate 11a can easily enter the soil, the resistance when the soiler 11 sinks into the soil can be reduced.

  Thus, by making the front-end | tip part of the wide plate 11a V shape in front view, mud can be cut | disconnected by the edge part of the V-shape, and the resistance of a soil can become small, and a carrot (I) can be floated effectively. it can. Therefore, the carrot (I) excavation work by the soira 11 can be performed smoothly. Further, the V-shaped portion of the wide plate 11a may be bladed as described above, or may be configured to be slidable back and forth.

FIG. 7 (a) shows an enlarged side view of the main part in the vicinity of the soiler 11 of another embodiment, FIG. 7 (b) shows a front view of FIG. 7 (a), and a tip portion of the wide plate 11a. A simplified diagram of is shown.
In addition, as shown in FIG. 7 (b), the wide plate 11a is tilted to the already-excavated side (right side in the forward direction of the root vegetable harvesting machine) so that the wide plate 11a is inclined upward to the right. The mud when digging up) flows in the direction of the arrow H and can be brought to the existing digging side, so that it is difficult for the mud to lean toward the end digging side (left side). If mud approaches the end digging side, the amount of mud increases and it becomes difficult to dig up, or mud adheres when digging up carrots (I). Can be prevented.

FIG. 8A shows an enlarged side view of the main part in the vicinity of the soiler 11 of another embodiment, FIG. 8B shows a front view of FIG. 8A, and the divided plate 11b as a wide plate. , 11c.
In addition, as shown in FIG. 8, the wide plate 11a may be divided into left and right parts, and the vertical height of the divided wide plates 11b and 11c may be changed to lower the wide plate 11c on the end digging side. By making the height of the wide plate 11c on the end digging side lower than the height of the wide plate 11b on the digging side, the mud when carrot (I) is dug up is the arrow H as in the configuration shown in FIG. Since it flows in the direction and can be brought to the existing digging side, mud is less likely to lean toward the end digging side (left side). Therefore, mud can be brought to the already excavated side.

In FIG. 9, the principal part enlarged view of the vicinity of the soiler 11 of another Example is shown.
In the wide plate portion of the soiler 11 of this embodiment, the wide plates 11 d and 11 d are connected to both ends of the member 27 by welding. In the vicinity of the front end of the soiler 11, in addition to the mounting hole 70b at the front end of the member 27, a plurality of inclination adjusting holes 70a for mounting the rear end of the member 27 are provided in the vertical direction with respect to the airframe. Yes. First attached to the mounting hole 70b of the distal end of the member 27, by fixing the one of the plurality of mounting holes 70a of the rear end portion of the parts material 27 to the next, the wide plate 11d, the longitudinal direction of the mounting angle regulation 11d It becomes possible. In this way, by adopting a configuration in which the wide plate 11a is tilted back and forth, it is possible to work in any state of the field without selecting the field conditions, so that the field adaptability is improved.

FIG. 10A shows an enlarged view of the main part in the vicinity of the soiler 11 of the present embodiment, and FIG. 10B shows a simplified front view of FIG. FIG. 10 shows an example in which the soy 11 of this embodiment is installed in a root vegetable harvesting machine provided with a vibrating soy 80.
The vibration soiler 80 is usually provided in a pair of left and right so as to be positioned on both sides of the carrot (a) in the soil sandwiched by the sandwiching belts 9L and 9R below the conveyance start end portion of the pair of left and right sandwiching belts 9L and 9R. The surrounding soil is embraced and oscillated in a shape that vibrates with the rear part supported on the horizontal axis.

  In this case, as shown in FIG. 10, the vibration arm 21 b is branched from the drive transmission unit 40 to the lateral pulling device 35 and attached between the crank rod 21 a and the crank rod 21 a and the machine frame 22 of the pulling and conveying device 9. The vibration power to the vibration soiler 80 is transmitted to the vibration arm 21b, and the vibration blade 21a is attached to the vibration arm 21b with a bolt or the like. The vibrating arm 21b may be provided with a plurality of mounting holes such as bolts so that the mounting position of the soira blade 80a can be changed.

  If you use the vibration soira 80 to loosen the surrounding soil by vibrating, when you harvest root vegetables from a clay field, it becomes difficult for the soil to solidify and pull out the root vegetables. By loosening the soil around (I), the Soira 11 can easily push out the carrot (I) from the soil, so that the work efficiency is improved. In the configuration shown in FIG. 10, the carrot (I) is pushed up by the soiler 11 before the soil is solidified. When harvesting root vegetables from such a field, it is possible to prevent mud from adhering to the root vegetables and to efficiently dig up the root vegetables.

  In addition, by arranging the wide plate 11a portion (the working portion when digging up) of the soiler 11 and the working portion 80a of the vibration soiler 80 at substantially the same position, the soil around the carrot (I) that is the target of harvesting is further increased. Can be loosened.

  Further, the vibration soiler 80 may be provided on both the left and right sides of the soiler 11, but as shown in FIG. 10, if the vibration soiler 80 is provided only on the left side, the muddy swell flowing when digging up is reduced and steering is performed. It becomes easy. If the vibration soiler 80 is provided on both the left and right sides, the amount of soil to be scraped increases, and the mud rises. If there is a lot of mud, the mud may become an obstacle during steering and the balance of the airframe may be lost. However, if the vibration soiler 80 is provided only on the left side, such a problem can be prevented. Moreover, since the mud when carrot (I) is dug up can be brought close to the already dug side (right side), mud does not easily approach the end dug side (left side).

FIG. 11A shows an enlarged view of the main part near the soiler 11 of the present embodiment, and FIG. 11B shows a simplified front view of FIG. 11A. Further, FIG. 11 (c) is a modified view of FIG. 11 (b) and illustrates a state in which the soil falls from the carrot (I).
FIG. 11 shows a case where a pair of left and right vibration soluers 80 </ b> L and 80 </ b> R is provided as the vibration sourer 80. And it is good also as a structure which arrange | positions the wide plate 11a part (action part at the time of digging up) of the soiler 11 ahead of the action part 80a of the vibration soilers 80L and 80R. In the example shown in FIG. 11, the wide plate 11a portion of the soiler 11 is arranged forward by a length Y from the action portion 80a of the vibration soluers 80L and 80R. Since the wide plate 11a portion of the soiler 11 acts on the carrot (I) prior to the vibration soira 80, the space where the carrot (I) was found (carrot (I)) Since mud begins to fall on the part where gaps are created due to floating, mud is less likely to adhere to carrots (I).

  When the vibrating soilers 80L and 80R act on the carrot (I) before the soiler 11, in the case of a clay field or the like due to the vibration of the vibrating soya 80, the soil may harden. After floating (a), the vibration soiler 80 is allowed to act to prevent such inconvenience, and loosening the soil after floating carrot (a) prevents adhesion of the soil and prevents carrot (i) ) Can be efficiently excavated.

  And as shown in FIG.11 (c), by setting it as the structure in which the space (M) is formed in the soiler 11 and the vibration soda 80, mud (b) flows in the arrow Z direction and falls into the space portion (M). , Mud (b) is more likely to fall from carrot (b). According to FIG. 11, the distance M between the vibration sourer 80R and the soiler 11 and the distance M between the vibration sourer 80L and the soiler 11 are the same. For example, the configuration is such that the unexcavated solitary 11 is brought closer to the center of the nipping and transporting action part of the drawing and conveying device 9 than the already excavated side of the soiler 11, and the unexcavated solitary 11 is less likely to contact the carrot (I). May be adopted.

FIG. 12 is an enlarged view of the vicinity of the remaining leaf processing roller 39 of the root vegetable harvester shown in FIG.
The carrot (I) transferred by the first conveyor 36 hits the remaining leaf processing roller 39 and is discharged onto the second conveyor 37. After being cut by the cutting device 31, the carrot (I) root side The leaves (remaining leaves) extending from the base of the stems and leaves remaining on the surface of the first conveyor 36 are rotated between the upper surface of the belt of the first conveyor 36 and the remaining leaf processing roller 39 by the rotation of the remaining leaf processing roller 39 in the direction of arrow A. It is pulled in and removed.

  In the conventional root vegetable harvesting machine, the length of the remaining leaf processing roller 39 is only halfway through the first conveyor 36 (the boundary between the large diameter portion and the small diameter portion in FIG. 12), and an attachment stay at the end of the remaining leaf processing roller 39 is provided. There was a problem that the carrot (I) stays between the belt (not shown) and the belt of the first conveyor 36, and a problem that the cut leaves stagnate in this vicinity and are easily clogged. Also, a lump of foreign matter such as pebbles is transported together with carrots (I), and foreign matter is caught between the remaining leaf processing roller 39 and the belt surface of the first conveyor 36, and the belt of the first conveyor 36 is broken. There was a problem of causing damage to the belt.

  However, as shown in FIG. 12, when the length of the remaining leaf processing roller 39 is extended to the end of the belt of the first conveyor 36, it is possible to prevent a problem that the carrot (I) and the cut leaves are accumulated. Further, if the remaining leaf processing roller 39 is composed of a large diameter portion and a small diameter portion, and the small diameter portion is an extended portion 39a, stone removal from the extended portion 39a is improved. As a result, it is possible to prevent the leading end portion of the carrot (b) from being caught by the terminal end portion of the remaining leaf processing roller 39 and being broken or causing a conveyance failure.

  Thus, by providing the small-diameter portion on the first conveyor 36 side end side of the remaining leaf processing roller 39, it becomes easy for the foreign matter such as pebbles to be discharged from the lower part of the extended portion 39a, and the foreign matter becomes the first. Since it is possible to prevent the conveyor belt of the conveyor 36 from being damaged, the remaining leaf processing is efficiently performed. The portion where the diameter of the remaining leaf processing roller 39 changes is preferably tapered as shown in FIG. 12, so that carrots (I) can be prevented from being damaged.

  Then, as shown in FIG. 12, a guide plate is arranged below the remaining leaf processing roller 39 so as to support the upper surface side of the conveyor belt of the first conveyor 36 from below, and the vertical position thereof is fixed. 50 is provided. A plan view of the guide plate 50 is shown in FIG. In addition, as shown in FIG. 13, the 1st conveyor 36 is spanned between a pair of rollers 36b and 36c.

  In the guide plate 50, the notch 50a is in the vicinity of the takeover portion between the first conveyor 36 and the second conveyor 37, so that the lump of soil and pebbles adhering to the carrots (a) together with the remaining leaves etc. When trying to pass below the remaining leaf processing roller 39, the belt 36 a can be retracted to the notch 50 a portion, so that a lump of soil and pebbles are placed between the first conveyor 36 and the remaining leaf processing roller 39. It is possible to prevent the belt 36a from being damaged by being bitten.

Then, a notched portion of 50a of the guide plate 50 of the lower belts of the start position S of the tapered first conveyor 36, the end position F of the taper, when the end of the guide plate 50, and the notches 50a and the tapered portion Since dirt blocks and pebbles easily pass between the belts, the belt is prevented from being damaged.

FIG. 14A shows an enlarged view of the root hair removing device 10 of the root vegetable harvesting machine in FIG. 1, and FIG. 14B shows an arrow view when viewed from the direction of arrow B in FIG. Indicates.
The root hair removing device 10 has an arcuate support guide 43 disposed at a position facing the inclined surfaces of the left and right conveying belts 9L and 9R. In the support guide 43, gaps 48 for guiding the roots of a plurality of carrots (a) are cut out at equal intervals and in parallel, and both ends thereof are located between the left and right outer plates 45L and 45R in the longitudinal direction of the machine body. It is fixed to.

  A rotating body 44 having a rotation axis 44a located on the virtual center axis of the arc is disposed inside the arc formed by the support guide 43 in FIG. The rotating body 44 is a member that is rotated by a motor 46 about its rotating shaft 44a. The rotating shaft 44a removably supports a mounting plate 53 with a roll bearing 81 attached to a right outer plate 45R by a bolt 83. Yes. The motor 46 is connected to the left outer plate 45 </ b> L by a bolt 82 via a motor mounting plate 52. In the illustrated example, the rotating body 44 is a box that combines two members 44 b and 44 c that are bent in a substantially U-shape, but may be S-shaped and rotates along the inside of the support guide 43. The root hair excision portion 49 is configured to excise root hair that passes through the gap 48 of the support guide 43.

  The conventional support structure of the rotating body 44 of the root hair removal device 10 is only a structure in which the motor 46 is connected to the left outer plate 45 </ b> L and the bolt 82 via the motor mounting plate 52. However, as shown in FIG. 14B, the rotating body 44 can be supported from both the left and right sides by connecting the rotating body 44 to the right outer plate 45 </ b> R by the roll bearing 81. By supporting the rotating body 44 from both the left and right sides in this way, the cutting posture of the root hair excision 49 can be stabilized, so that the cutting processing work for the carrot (I) lower part (root root of the root vegetable) is stabilized. Efficiency is improved.

  With the configuration of the root hair removing device 10, it is possible to reduce the occurrence of defective root hair removal due to clogging of soil or the like in the adjacent gap 48. Further, by forming a plurality of gaps 48 of the support guide 43 in the left-right direction, the left-right width of the root hair removal action area is widened, and the transporting posture of the carrots (I) being transported by the sandwiching transport belts 9L, 9R is slightly lateral. Even if it is inclined or bent carrot (I), the root hair can easily enter the gap 48 between the support guides 43, and root hair can be removed more appropriately than before. Furthermore, in the crops that are transported sequentially, even if the crops that are transported in advance are long, the lower end of the next transported carrot (i) shifts to the left and right, and the root hairs precede it. Since it is possible to enter the gap 48 between the support guides 43 different from the gap 48 into which the root hair enters, root hair removal can be performed more appropriately than in the past.

Further, since the plurality of gaps 48 are notched in the support guide 43, even if dirt or the like enters the gap 48 of the support guide 43, it is easy to come out, the clogging of the gap 48 is difficult to occur, and root hair removal can be performed more appropriately.
Furthermore, by configuring the rotating body 44 in a box shape, the root hair can be excised across the width in the left-right direction of the support guides 43 at the left and right ends where the root hair can be removed, and the strength is high and it is difficult to bend. Durability is improved.

  The arm 85 that supports the mounting plate 53 of the roll bearing 81 is connected to the roll bearing 81 of the root hair removing device 10 by a bolt 83 in the vicinity of the center, and the front and rear portions of the arm 85 are perpendicular to the vertical direction. It is attached at an angle of θ (FIG. 14A). The reason why the inclination angle θ is provided is to prevent the mud soil adhering to the carrot (a) from being collected even if it falls, but if the inclination angle is too large, the arm 85 interferes with the rotary blade 49. A predetermined inclination angle θ is set.

  If the value of the inclination angle θ is too small, soil adhering to the carrot (I) root will accumulate on the arm 85. Therefore, if the value of the inclination angle θ is set to a small value or 0, the soil adhering to the root of the carrot (A) flows in the direction of arrow D, so that the soil does not accumulate on the arm 85. .

  And the mounting hole of the bolt 82 provided in the plate 45L is made into the long hole 45La, and except the motor mounting plate 52, the support guide 43, the rotary body 44, the motor 46, and the arm 85 can be adjusted integrally. Although the length of the root portion varies depending on the type of root vegetable, since the height of the rotary blade 49 of the root hair removing device 10 can be adjusted by adopting this configuration, various types of root vegetables can be handled.

  FIG. 15 (a) shows an enlarged left side view of the root hair removing device 10 of the root vegetable harvesting machine according to another embodiment, and FIG. 15 (b) is a view from the direction of arrow B in FIG. 15 (a). An arrow view of the case is shown. FIG. 15C is an enlarged right side view of the root hair removal device 10 of FIG. Further, FIG. 16 (a) shows a sectional view of the motor portion of the root hair removing device 10 of the conventional root vegetable harvesting machine, and FIG. 16 (b) shows a sectional view of the motor portion of the root hair removing device 10 of FIG. 15 (b). (Corresponding to the longitudinal sectional view of FIG. 15B).

  Further, as shown in FIG. 15B, the gap 48 of the support guide 43 may be inclined in the left-right direction. In FIG. 15 (b), it is inclined upward to the right, but may be inclined downward to the right. Thus, by arranging the gap 48 at an angle, the root hairs of the tip part (tail part) of the carrot (A) are guided into the gap 48 and become easy to enter. Therefore, the lower part of the carrot (I) can be cut more reliably, and the value of the harvested carrot (I) is improved.

  Further, it is preferable to provide the end portion of the support guide 43 as shown in a dotted line G portion, for example, so as to be separated from the circumference of the outer plate 45 (dotted line E portion). When the end portion of the support guide 43 is provided along the circumference of the outer plate 45 (dotted line E portion), soil accumulates in the round frame portion K, the rotary blade 49 hits the soil, and the rotary blade 49 touches the soil. It will be shaved by. In particular, since the soil adhering to the carrot (I) is carried together with the carrot (I) at the end portion of the crosspiece 43a, the soil tends to collect. However, as shown in FIG. 15A, by providing the end portion of the support guide 43 away from the circumference of the outer plate 45 (dotted line E portion), the soil accumulated in the round frame portion K falls down. In addition, it is possible to prevent the root hair excision rotating blade 49 from being scraped by the soil.

  Moreover, it is good to fold down the folding | returning part 43aa of the rear-end part of the support guide 43 rather than a horizontal part (dotted line P position). When the folded portion 43aa at the rear end of the crosspiece 43a is positioned on the dotted line P, soil accumulates above the folded portion 43aa. When the soil accumulates above the folded-back portion 43aa, it gradually enters the gap 48 between the crosspieces 43a, causing the soil to accumulate on the back side of the crosspiece 43a. However, it is possible to prevent soil from accumulating above the folded portion 43aa by lowering the folded portion 43aa below the horizontal portion (the position of the dotted line P) and providing an inclination.

  Further, the front portion 43ab of the support guide 43 may be provided so as to be forward and downward with respect to the horizontal plane (dotted line Q position) without being provided along the horizontal plane (dotted line Q position). If the front part 43ab of the support guide 43 is folded back along the horizontal plane (dotted line Q position), when the soiler 11 is lifted up, soil accumulates in the vicinity of the turn-back and is difficult to fall. However, since the soil falls forward by inclining the front portion 43ab of the support guide 43 so that the angle becomes steep with respect to the horizontal plane (dotted line Q position), such a problem can be prevented.

  Further, as shown in FIG. 15 (a), the vicinity of the center of the support guide 43 forms an arc-shaped circumferential portion in a side view, but if the rear circumferential portion is made shorter than the front circumferential portion. Since the area of the support guide 43 can be minimized, the root hair removing device 10 can be made compact. This is because the front circumference needs to have a certain length in order to accept long roots such as carrots (I), but the rear circumference is rotated because the rotary blade 49 has already excised the root hair. This is because the blade 49 only needs to have a circumferential portion up to a position where the soil falling from the carrot (I) does not hit, so that it can be shorter than the circumferential portion on the front side.

  Then, the front portion 45Ra of the right outer plate 45R on the side where the gap 48 is inclined is bent outward. This is because the root of carrot (I) is difficult to enter because there is a portion where the support guide 43 is not cut out on the side where the gap 48 is not inclined even if both are widened. Moreover, you may widen the entrance part of the root hair removal apparatus 10 so that the root part of a carrot (I) may enter easily.

By adopting the above configuration, it is possible to prevent the carrot (I) root from striking the outer plates 45L and 45R and becoming difficult to enter the plurality of gaps 48 cut out in the support guide 43 of the root hair removal device 10.

  Further, the outer plate 45 and the support guide 43 are configured to be connected by providing notched portions 45a and 45b on both of them and aligning the notched portions 45a and 45b. Then, as shown in FIG. 15 (c), if the length of the front notch 45a of the alignment portion of the outer plate 45 and the support guide 43 is made longer than the length of the rear notch 45b, it will be cut by incorrect assembly. Since the lengths of the notches are different, they cannot be connected. Therefore, erroneous assembly of the outer plate 45 and the support guide 43 can be prevented.

  In the example shown in FIG. 15C, the length of the front notch 45a is made longer than the length of the rear notch 45b, but the length of the rear notch 45b is made longer than the front notch 45a. In other words, the length of the notch 45a or 45b in the alignment portion may be changed before and after. Moreover, it is not limited to the length of the notches 45a and 45b, but the shapes of the notches 45a and 45b may be different.

  Also, as shown in FIG. 16A, since the right outer plate 45R is conventionally provided at the right end of the support guide 43, the corner (arrow) of the connecting portion between the right outer plate 45R and the support guide 43 is shown. There is a problem in that the soil easily collects in (J portion), and the blade portion of the rotary blade 49 is damaged by the soil. However, as shown in FIG. 16B, by providing the right outer plate 45R on the support guide 43, the corner (arrow J portion) is eliminated and the right outer plate 45R and the support guide 43 are connected. It is possible to prevent soil from accumulating in the part.

  Further, the root hair chips and soil cut and blown off by the root hair cutting section 49 are configured to prevent scattering to the outside by hitting the outer plate 45, but the conventional configuration shown in FIG. Then, there was a problem that root hair chips and soil were easily scattered. However, as shown in FIG. 16 (b), by taking a longer distance N from the rotation shaft 44a to the right end of the support guide 43 than in the configuration shown in FIG. It is possible to suppress scattering to the outside.

  The present invention can be used as an agricultural machine as a root vegetable harvester.
