Abstract

PROBLEM TO BE SOLVED: To work safely by preventing a cutter from coming near a human body. SOLUTION: When a radish is carried by a carrying conveyor 6b, a safety frame 30 usually lowered and acting as a stopper is pushed and lifted up by the stalks of the radish. When the stalks are carried by the carrying conveyor 6b, they push up the safety frame 30 and then the stalks of the radish are cut by a cutter 7. The cut stalks drop under their own weight and the downward force by the weight of the moving-up safety frame 30 presses down the stalks to assist the cutter 7 to cut the stalks and to assist the cut stalks to drop. Therefore, the safety frame 30 prevents the operator' s body or clothes from accidentally coming near to the cutter 7 during work to improve safety.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary machine for harvesting root vegetables such as radish or leaf vegetables such as cabbage.

[0002]

2. Description of the Related Art An example of a conventional harvesting assisting machine will be described by taking root vegetables such as radish as an example of a harvest. The conventional harvesting assisting machine pulls radish from a cultivated land by hand and sends it to a conveyor of the harvesting assisting machine. It is to run on the field while cutting and cutting the foliage by the cutter provided at the place adjacent to the conveyor while transporting it on the conveyor, and loading only the root part manually into the storage container to be mounted on the rear of the harvesting auxiliary machine sequentially. It is.

[0003]

In the above-mentioned harvesting assisting machine, a cutter having a disc-shaped outer periphery having a saw-shaped blade for cutting off the foliage of the harvested material and having a high-speed rotating cutter is provided. Touching clothes can cause a serious disaster, so safety measures such as installing a safety cover that covers the blade of the cutter have been taken in the past. Safety measures to prevent the approach of the human body and the like can be carried in, and it is desired to improve the safety. Therefore, an object of the present invention is to provide a harvesting assisting machine that can prevent a human body or the like from approaching a cutter and can work safely.

[0004]

The above object is attained by the following constitution of the present invention. That is, in a harvesting auxiliary machine including a conveyor for transporting the crops extracted in the field and a cutter for cutting the foliage of the crop being transported by the transport conveyor on one side of the transport conveyor, This is a harvesting assisting machine provided with a movable safety frame means which is pushed up by the crops conveyed to the cutter and is lowered so as to protect the sides of the cutter after cutting the crops.

[0005] When crops such as radish are conveyed by the conveyor, the safety frame, which normally lowers and serves as a stopper, is pushed up by the foliage of the crops and rises. With the transport of the transport conveyor, the foliage of the harvested product pushes up the safety frame, and then the foliage is cut by a cutter. Although the cut foliage falls under its own weight, the downward force due to the self-weight of the rising safety frame presses the foliage at the time of cutting downward to assist cutting, and also helps the fall of the foliage after cutting. Act like so.

[0006] With the construction in which the cutter is provided with the safety frame capable of swinging up and down as described above, the operator's body or clothes can be prevented from accidentally touching the cutter during work when cutting the foliage of the crop. The safety frame prevents the approach to the vicinity of the cutter, so that the safety is extremely improved. Further, after the cutting of the foliage, the effect of lowering the foliage by the descending force of the safety frame is also obtained. . Further, since tension acts on the foliage, cutting performance by the cutter is also improved. The harvest assistant of the present invention can be applied to root vegetables such as radish and carrot and leaf vegetables such as cabbage and lettuce.

Is fixed to the vehicle body 3 near the conveyor rotating shaft 10 with pins 11 in order to fix the conveyor 6 in a state where the longitudinal direction faces the side surface of the conveyor. The height of the conveyor 6 is a curved arm 13 (a pair of arms 13a and 13b) supporting the conveyor 6 (a pair of conveyors 6a and 6b) on both sides.
It is adjusted by the cylinder 12 that connects the support member 14 and the conveyor rotating shaft 10 in b) (FIG. 2).

As shown in FIG. 2, the conveyor 6 (a pair of conveyors 6a and 6b) is composed of a pair of endless chains 16 having both sides supported by curved arms 13 (a pair of arms 13a and 13b). A chain 17 (see FIG. 3) meshes with sprockets 122, 123 and 119, 121 (see FIG. 4) supported on both ends of the curved arms 13a, 13b.

Plates 18 and 19 are attached to the chains 16 and 17 in a ladder shape, respectively.
The rivets 23 and 24 fix the important parts of the sheets 21 and 22 so that the waves 22 undulate on the respective chains 16 and 17. Since the radish is placed on each of the valleys of the corrugated belt-shaped elastic sheets 21 and 22 and conveyed, the radish does not roll off the conveyor 6 (see FIG. 3).

The pair of endless chains 16 are arranged in parallel at an interval. A wide band-like elastic sheet 21 is attached to the endless chain 16, and a narrow band-like elastic sheet 21 is attached to the endless chain 17. A seat 22 is attached. The root portion of the radish is placed on the conveyor 6a having the wide band-shaped elastic sheet 21, and the foliage portion of the radish is placed and transported on the conveyor 6b having the narrow band-shaped elastic sheet 22.

The radish root portion is placed on the elastic sheet 21 of the root conveyor 6a, and the radish foliage portion is placed and transported on the elastic sheet 22 of the foliage cutting conveyor 6b.
Even if the foliage is cut by the cutter 7 (rotary blade) during the transport, the root portion is transported toward the cradle 8 in a stable state (see FIG. 3).

FIG. 4 shows a main part of the driving mechanism. The driving force of the engine 100 is obtained by winding one end of an endless V-belt 103 around an engine output pulley 102 which rotates together with an engine output shaft 101. The end is wound around an HST pulley 107 fixed to an input shaft 106 of a hydrostatic transmission (HST) 105 to drive an HST swash plate type variable displacement axial plunger pump 109. The amount of oil discharged to the constant displacement hydraulic motor 110 in accordance with the amount of change in the inclination angle of the swash plate (not shown) provided on the pump 109 (the operation of changing the inclination angle with the HST lever located in the driver's seat 5). change. The change in the amount of oil discharged to the constant displacement hydraulic motor 110 causes the motor 11
0 rotation shaft (not shown) changes, the traveling device 1
The rotation speed of the input shaft 11 (not shown) also changes, and finally the rotation speed of the crawler 2 changes, and the running speed of the root crop harvesting auxiliary machine 1 changes.

When the HST lever (not shown) in the driver's seat 5 is in the neutral position, oil is not supplied to the constant displacement hydraulic motor 110, and the crawler 2 does not rotate. When the HST lever is moved forward (or backward), a swash plate (not shown) provided on the pump 109 is inclined, and oil is supplied to the constant displacement hydraulic motor 110.

A work machine pump 112 is provided at a shaft end of the HST input shaft 106 on the side opposite to the HST pulley 107, and the pump 112 rotates at a constant speed in synchronization with the speed of the engine 100. The working fluid is supplied to the conveyor 6 and the cutter 7 while maintaining a constant pump discharge amount.

Here, the hydraulic circuit of the HST 105 and the pump 1
12, the hydraulic circuit of the motor 115 is independent, and the oil tank of the HST 105 is not shown. H
In ST105, the oil tank, the pump 109, and the motor 110 circulate oil in a closed circuit.

The oil tank 135 supplies oil to the hydraulic circuit of the working machine pump 112 and the motor 115, and the root crop harvesting auxiliary machine 1
When the vehicle travels on the road, the conveyer 6 and the cutter 7 are not driven, so the oil from the oil tank 135 is only switched by the pump 112 by switching the valve 114 and returned to the oil tank 135. When using the pump, switch the valve 114 to
The oil from the valve 12 switches the valve 114 so that the hydraulic motor 1
The hydraulic motor 115 drives the endless chains 16, 17 of the conveyor 6 and the cutter 7 via a series of sprockets 116 to 123 and chains 130 to 133. After these tasks, the oil is stored in tank 1
Returned to 35.

FIG. 5 shows a mechanism for driving the endless chains 16 and 17 of the root conveyor 6a and the foliage conveyer 6b via sprockets 116 to 123 and chains 130 to 133, and a side surface of a chain 134 for driving the foliage cutter 7. The figure is shown.

FIG. 6 is a partially cutaway perspective view of the vicinity of the cutter 7 showing a safety frame 30 which is a feature of the embodiment of the present invention. The cutter 7 has a pair of bearings 134b, 13 of a cutter rotating shaft provided at the other end of the chain cover 134a, one end of which is supported at the top of the conveyor rotating shaft 10.
The cutter rotating shaft 7a is supported by 4b, and the cutter 7 and the sprocket 120 are fitted on the cutter rotating shaft 7a and driven by a chain 134 (FIG. 5). The fixed cover 7b has an inverted U-shaped cross section in the vertical direction, and covers from the upper part of the cutter 7 to the upper part of the terminal part of the foliar cutting conveyor 6b,
The lower part is higher than the endless chain 17 of the foliage cutting conveyor 6b by the height h so that the foliage of the radish can pass freely. First movable covers 7c, 7c which can swing up and down around fulcrums 7d, 7d are provided on both sides of the fixed cover 7b on the side of the foliage cutting conveyor 6b, and both sides of the fixed cover 7b which are close to the cutter rotating shaft 7a are provided. The second movable covers 7e, 7e which can swing up and down around the fulcrums 7f, 7f are provided, and the safety frame 30 which can swing up and down around the fulcrum 30a is provided on the side of the conveyer turning shaft 10 of the chain cover 134a. ing.

Each of the first movable covers 7c, 7c and the second movable covers 7e, 7e has a substantially triangular side shape and has fulcrums 7d, 7d and 7f, 7f near its apex, respectively.
And always covers both sides of the cutter 7. The safety frame 30 has a pipe-like cross-section in the shape of a circular arc or a polygon protruding downward in the longitudinal direction, and has one end supported by a fulcrum 30a, and is always in contact with a stopper 30b to be in contact with a stopper 30b. And extends to the starting end side of the foliage cutting conveyor 6b.

The first movable cover 7c and the second movable cover 7e having a triangular shape have their centers of gravity at fulcrums 7d and 7f.
Because it is far away from the
When the radish is conveyed by the conveyor 6 in the direction of the arrow a, the first movable cover 7c is pushed up by the foliage of the radish and rises in the direction of the arrow b. 7e is pushed up and rises in the direction of arrow c. Since the center of gravity of the pipe-shaped frame is away from the fulcrum 30a, the safety frame 30 is normally lowered to abut against the stopper 30b, and extends substantially parallel to the side surfaces of the cutter 7 and the foliage conveyor 6b. .

However, when the radish is conveyed by the conveyor 6, the safety frame 30 is pushed up by the foliage of the radish and rises in the direction of arrow d. As the conveyor 6 is transported, the foliage of the radish is moved to the first movable cover 7.
c, The second movable cover 7e and the safety frame 30 are pushed up, and then the foliage is cut by the cutter 7. Although the cut foliage falls under its own weight, the downward force due to the self-weight of the rising safety frame 30 presses the foliage at the time of cutting downward to assist cutting, and assists the fall of the foliage after cutting. Acts to be.

As described above, the cutter 7 shown in FIG. 6 has a movable cover 7c that can swing up and down on both sides of the fixed cover 7b.
7e and a safety frame 30 that can swing up and down in parallel with the foliage cutting conveyor 6b, so that when the foliage of the radish is cut, the movable covers 7c and 7 are transported by the foliage.
e and the safety frame 30 can be pushed up to cut without any trouble, and the cutting performance is remarkably improved because the cutting is performed by the cutter 7 while pressing the foliage of the radish downward by its own weight. In addition to the cover being lowered to cover and keep the cutter safe, and because the safety frame 30 extends parallel to the foliar cutting conveyor, the operator's body and clothing can accidentally fall on the cutter 7 during work. Before touching, the safety frame 30 prevents the cutter 7 from approaching the vicinity of the cutter 7, and the safety is extremely improved. After the cutting of the foliage, the falling of the foliage is prevented by the descending force of the safety frame. The effect of assisting is also obtained.

As shown in a perspective view from the rear side of the root vegetable harvesting auxiliary machine 1 in FIG. 7 as the root vegetable harvesting auxiliary machine 1 according to the embodiment of the present invention, Direction (arrow f) opposite to the transport direction (indicated by arrow a)
By adopting the configuration in which the reduction conveyor 40 and the shooter 41 are provided, the unadjusted radish can be selected and the foliage can be cut again by the cutter 7.

That is, the starting end of the reduction conveyor 40 is connected to the storage net (or receiving table) near the end of the conveyor 6.
8 and the end of the reduction conveyor 40 is arranged in the vicinity of the bending of the arm 13 of the transport conveyor 6. The starting end of the shooter 41 is connected to the end of the reduction conveyor 40, and the shooter 41 extends slightly forward of the conveyor 6 in a direction perpendicular to the conveyor 6 (arrow g) in a plan view, and the end ends from the ground of the field. It has descended to a slightly higher position.

The reduction conveyor 40 may be a roller conveyor utilizing gravity. However, it is preferable that the chain is driven by using the engine power in the same manner as the transportation conveyor 6 so that the reduction transportation can be performed at an appropriately controlled speed. . The shooter 41 is a slide-type slope having an appropriate slope, but may be used as a roller conveyor.

Thus, the foliage harvested in the field is the cutter 7
Is finally stored in the storage container 4 (FIG. 1). Conventionally, all the radish was stored in the storage container 4. However, if the structure shown in FIG. When the radish is stored in the container, the cutting condition of the foliage is inspected. If a radish having a defective cut portion is found, the radish is not stored in the container 4 but is mounted on the reduction conveyor 40. Defective radish is reduced conveyor 40
Is descended in the direction of the arrow f, and the shooter 41 further proceeds while rolling substantially in the direction of the arrow g to land on the ground of the field. The landing position of the poorly cut radish is near the feet of the harvester, and the harvester picks it up and reloads it on the transport conveyor 6, where the foliage is cut again by the cutter 7, and the radish becomes a well-cut radish. It is stored in the container 4 from the end of the conveyor 6 via the storage net (cradle) 8.

Therefore, all the radishes stored in the container 4 have good cut surfaces, so that the conventional sorting operation and the re-cutting operation of the foliage of the defective radish after the sorting can be omitted, and the efficiency of the radish harvesting operation can be reduced. improves. By appropriately selecting the transport speed of the reduction conveyor 40 and the inclination angle of the shooter 41, it is possible to prevent the quality of radish from being reduced by the reduction transport.

As shown in the side view of the root crop harvesting auxiliary machine 1 of FIG. 8 and the partially cutaway plan view of the root crop harvesting auxiliary machine 1 of FIG. 9, the unloading operation of the full container 4 is facilitated. Alternatively, a configuration for performing the operation may be used.

The root vegetable harvesting assisting machine 1 of this embodiment has a carrier (foldable vehicle body) 50 on which a container 4 can be loaded and which can be tilted as required, above the vehicle body 3. Is connected to the substantially lower center of the carrier 50 and the rear part of the vehicle body 3 by a tilting fulcrum 51, and furthermore, the carrier 50 and the vehicle body 3 are connected by a carrier tilting cylinder 52, and tail wheels 5 provided on the rear left and right of the carrier 50 are provided.
When the carrier 50 is tilted, the carrier 50
The mounting structure can be tilted with respect to.

With the above structure, the carrier 50 keeps its upper surface horizontal during normal times such as during a harvesting operation, and at the time of the following unloading operation, the carrier tilting cylinder 52 is reduced to raise the front portion and lower the rear portion. 8 can be tilted as shown by the arrow g in FIG.

A pair of tail wheels 53 are 53
In the prior art, a U-shaped bracket 55 for supporting the tail wheel rotating shaft 54 is directly fixed to the carrier 50 or the vehicle body 3 in order to partially support the running stability and the load of the crawler 2. In the root crop harvesting assisting machine 1 shown in FIG. 9, a U-shaped bracket 55 is fixed to a tail wheel turning bracket 56, and the tail wheel turning bracket 56 is rotatably supported by a tail wheel turning fulcrum 57. Is fixed to a tail wheel stopper 58 fixed to the carrier 53 by a tail wheel fixing pin 59 so as not to rotate.

When the container 4 is to be unloaded from the carrier 50 which has been loaded and held horizontally during the harvesting operation, the root crop harvesting auxiliary machine 1 is stopped at a predetermined position, and the tail wheel fixing pin is first set. 59 is pulled out so that the tail wheel 53 can be freely rotated with respect to the carrier 50. Next, when the carrier tilt cylinder 52 is operated, the carrier 50 tilts in the direction of arrow g, and the upper surface of the carrier 50 tilts. At this time, since the tail wheel 53 is rotatable with respect to the carrier 50, the tail wheel 53 is relatively rotated in the direction of the arrow h while being in contact with the rear of the carrier 50, and does not hinder the tilting of the carrier 50.

When the inclination angle of the upper surface of the carrier 50 reaches an appropriate value, the container 4 starts to slide due to gravity and lands on the field from above the carrier 50. If necessary, the container 4 can be completely landed by advancing the root crop harvesting auxiliary machine 1 at a slow speed or assisting it manually.

Therefore, when the container 4 loaded on the carrier 50 is full, the fixing of the tail wheel 53 can be released, the carrier 50 can be tilted, the container 4 can be slid, and the landing can be made on a field, such as a forklift or a crane. Since the container 4 can be unloaded at a place where there is no equipment, there is no need to temporarily suspend the harvesting operation and move the root crop harvesting auxiliary machine 1 to the place where the unloading equipment is located. It is possible to obtain an extremely large effect in improving the efficiency of the harvesting operation, for example, because no special equipment is required.

As shown in the plan view of the root crop harvesting auxiliary machine 1 in FIG. 10 and the side view of the root crop harvesting auxiliary machine 1 in FIG. 11, the vehicle body 3 of the root vegetable harvesting auxiliary machine 1 or the deck 60 mounted on the vehicle body 3. A plurality of rollers 61, 6 having a rotation axis in a direction orthogonal to the traveling direction of the root crop harvesting auxiliary machine 1
The structure provided with 1, 61,... Can also facilitate the unloading operation of a full flexible container bag (hereinafter abbreviated as a flexible container bag) 4a.

During the radish harvesting operation, the flexible container bag 4a is loaded on the deck 60, and the harvested radish is stored in the flexible container bag 4a. The flexible container bag 4a is placed directly on the roller 61. However, it is preferable to place the board 4b such as a pallet on the roller 61, and to mount the flexible container bag 4a on the board 4b.

When the flexible container bag 4a is full and the flexible container bag 4a is to be unloaded from the deck 60, the root crop harvesting auxiliary machine 1 is stopped and the flexible container bag 4a on the deck 60 is manually pushed out. The roller 4a can move lightly due to the rolling operation of the rollers 61, 61, 61,... And lands on the field from above the deck 60. After one end of the flexible container bag 4a lands, the entire flexible container bag 4a can be landed by advancing the root crop harvesting auxiliary machine 1 at a low speed. FIG. 12 is a partially cutaway side view showing the operation of another embodiment. The figure is shown. In this case, the rear part 60a of the deck 60 is partially inclined downward as shown in the figure, and the height H of the rear end of the deck rear part 60a is reduced, so that the impact when the flexible bag 4a lands on the field from the deck 60 is reduced. Is relaxing.

That is, after the flexible container bag 4a on the deck 60 is pushed out from the direction shown in FIG. 12, one end lands as if it is obliquely descended on the inclined portion 60a at the rear of the deck, and then the root vegetable harvesting assistance is performed. By moving the machine 1 at a slow speed, the entire flexible container bag 4a can be landed with less impact.

Thus, as shown in FIGS. 10 to 12, a plurality of rollers 61 are provided on the upper surface of the vehicle body 3 or the deck 60 mounted on the vehicle body 3, and the flexible container 4a is loaded on the rollers 61. Thus, when the loaded flexible container bag 4a is full, the flexible container bag 4a can be lightly pushed out by human power and landed on the field, and the flexible container bag 4a can be unloaded at a place where there is no equipment such as a forklift or a crane. Therefore, there is no need to temporarily suspend the harvesting work for unloading and move the root crop harvesting auxiliary machine 1 to the place where the unloading equipment is located, and no special equipment for unloading is required. Contributes to the efficiency improvement of

In the above-described embodiment, the plurality of rollers 61 are provided on the upper surface of the vehicle body 3 or the deck 60. Instead, the upper surface of the vehicle body 3 or the deck 60 is made flat,
The same effect can be obtained even if a plurality of rollers are provided on the lower surface of the plate base 4b such as a pallet.

FIG. 14 is a perspective view of the front cover 6c of the conveyor 6 of the conventional root crop harvesting auxiliary machine 1, and FIG. 13 shows the root crop harvesting auxiliary machine 1 according to the embodiment of the present invention viewed obliquely from the front. Although shown in a perspective view, the present invention relates to a configuration in which the weight of the front cover 6c can be reduced in order to reduce the load acting on the turning shaft 10.

During the harvesting operation, the height of the conveyor 6 is adjusted and the conveying speed is adjusted according to the conditions in the field, the growing condition of the root vegetables, and the like. The height of the conveyor 6 is
Support member 14 of a curved arm 13 for supporting on both sides
12 connecting the conveyor and the conveyor rotating shaft 10
The transfer speed is adjusted by controlling the valve 114 to control the flow rate of the working oil supplied from the working machine pump 112 to the hydraulic motor 115 shown in FIG. 4, but conventionally, as shown in FIG. The adjustment operation is performed by an operation switch provided in the driver's seat 5 or a front cover 6 c at the end of the conveyor 6.
A configuration that can be performed from any of the switches of the switch box 6d provided in the first embodiment is adopted.

However, the front cover 6c is
, And is located at a position farthest from the rotating shaft 10, so that the weight of the front cover 6 c has been a problem in order to reduce the load acting on the rotating shaft 10.

Therefore, in the embodiment shown in FIG. 13, the front cover 6c (FIG. 14) which entirely covers the front end portion of the conveyor 6 is replaced with a front cover 7c.
0 is located on the upper surface 70a of the corrugated belt-shaped elastic sheets 21, 22
And the switch box 71 is attached to the front surface 7 of the front cover 70 so as to have a height corresponding to the height of the valley bottom.
0b so as not to protrude from the front cover upper surface 70a.

Since the switch box 71 does not protrude from the front cover upper surface 70a in this way, radish can be loaded on all the valleys of the corrugated belt-like elastic sheets 21 and 22 on the upper surface of the conveyor 6, and the work area of the conveyor 6 can be reduced. It becomes wider and a large amount of radish can be loaded, so that the efficiency of the harvesting operation is remarkably improved, and the weight of the front conveyor 70 is reduced, so that the weight of the conveyor 6 is reduced, and the load acting on the rotating shaft 10 can be reduced. However, if the same working area and the same working capacity as before can be used, the length of the conveyor 6 can be shortened, so that the root crop harvesting auxiliary machine 1 can be further reduced in size and weight.
