At the same time, the corrugated belt-shaped elastic sheet 21 (FIG. 5) is attached, and the root of the radish is received and conveyed in the corrugated valley, and the other row is an auxiliary lug 26 (FIG. 5) for guiding the foliage by the foliar cutting conveyor 6b. 7), the foliage is received and transported between a pair of two auxiliary lugs 26, 26, and passed through the cutter 7 provided between the root conveyor 6a and the foliage cutting conveyor 6b, so that the foliage is formed. Be cut off. Since the cutter 7 has a disk shape and has a saw-shaped sharp blade on the outer periphery and rotates at a high speed, the radish can be cut lightly.

When the radish is not harvested, the conveyor 6
Is fixed so that the longitudinal direction is directed forward in the traveling direction so as not to obstruct the movement of the root vegetable harvesting assisting machine 1. A rotating shaft 10 for moving the conveying conveyor 6 in the direction is provided on the vehicle body 3 so that the longitudinal direction can be moved. The transport conveyor 6 is fixed to the vehicle body 3 near the rotating shaft 10 with pins 11 in order to fix the transport conveyor 6 in a state where the longitudinal direction faces the side surface of the vehicle body 3. The height of the conveyor 6 is adjusted by the expansion and contraction of the cylinder 12.

The conveyor 6 has endless chains 16, 1
7, ladder-shaped plates 18, 18,... (FIG. 6) that are stretched over a pair of endless chains 16, a corrugated elastic sheet 21, and endless chains 16, 17 at both ends of the conveyor 6. It consists of meshing sprockets 122, 123 and 119, 121 and the like.

As shown in FIG. 8, the endless chains 16 and 17 are roller chains in which cocoon-shaped plates 20a and 20b made of a steel plate are connected by pins 20c. Cocoon-shaped plates (pin link plates) 20a, 20a

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 changes the rotation speed of the rotation shaft (not shown) of the motor 110, and also changes the rotation speed of the input shaft (not shown) of the traveling device 111. ,
Eventually, the rotation speed of the crawler 2 changes, and the traveling speed of the root crop harvesting auxiliary machine 1 changes.

When the HST lever (not shown) in the driver's seat 5 is at the neutral position, oil is not supplied toward 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 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 work 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 12 is sent to the hydraulic motor 115 side, which drives the endless chains 16, 17 and the cutter 7 of the conveyor 6 via a series of sprockets 116 to 123 and chains 130 to 132. The oil after performing these tasks is returned to the tank 135.

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 132, and a side surface of the chain 134 for driving the foliage cutter 7. The figure is shown. The cutter 7 is located in the gap between the root conveyor 6a and the foliage cutting conveyor 6b,
Is provided in the vicinity.

However, the bottom of the corrugated belt-like elastic sheet 21 of the conventional root conveyor 6a is fixed to the ladder-like plate with rivets 23 (FIG. 6) and cannot be deformed. The radish receives the action force of the cutter 7 and presses the corrugated belt-shaped elastic sheet 21 because of the action of the pressure and the rotating force, and the chevron portion thereof is easily deformed. However, there is a problem that needs to be solved, such as falling from the conveyor 6 or moving the radish mounting position during the conveyance by the cutter 7 to make the cut surface irregular.

Therefore, the embodiment of the present invention shown in FIGS.
As shown in FIG. 10, a part of the pin link plate 20a of the endless chain 16 of the root conveyor 6a is replaced with an inverted Y-shaped lug mounting plate 20f. Holding mounting holes,
The lower two holes fix the roller chain pin 20c in the same manner as the pin link plates 20a and 20b, and the upper mounting hole fixes the lug mounting pin 25a of the lug 25, and the lug mounting pin 25a The lug mounting hole 25b is rotatably and non-detachably fitted (see FIG. 8).

The lug mounting plate 20f is mounted such that the lug 25 mounting position coincides with the peak of the corrugated belt-like elastic sheet 21. The pin link plate 20a at a position corresponding to the valley of the wavy elastic sheet 21 in the middle of the two lug mounting plates 20f is the ladder plate 1
It has been replaced with a mounting plate 20g for mounting 8.

In this way, the lug 25 is attached to the endless chain 16 of the root conveyor 6a at a position corresponding to the crest of the corrugated strip elastic sheet 21 and moves together with the root conveyer 6a. 25
Are always in phase in synchronization.

Therefore, when the radish can be conveyed by mounting the root of the radish in the valley of the corrugated belt-shaped elastic sheet 21 as in the conventional case, and when the pressing force of the cutter 7 is received when the radish is cut by the cutter 7, First, the root of the radish presses and deforms the corrugated belt-shaped elastic sheet 21, but when the root of the radish comes into contact with the lug 25, the pressing force of the cutter 7 is received by the lug 25, and the corrugated belt-shaped elastic sheet 21 is further deformed. It works so that there is nothing.

Further, the pressing force when cutting the radish foliage by the cutter 7 can be received by the lug 25,
Radish does not fall off the conveyor 6
In addition, cutting performance can be improved because cutting can be performed stably.

Also, as shown in FIG.
The endless chain 17b has the same configuration as the endless chain 16, and differs from the root conveyor 6a in that the endless chain 17 does not include the corrugated belt-like elastic sheet 21. The mounting positions of the auxiliary lugs 26 of the endless chain 17 corresponding to the lugs 25 of the endless chain 16 are both corrugated belt-like elastic sheets 21.
Is arranged so as to coincide with the peak of.

Thus, the endless chain 1 of the foliage cutting conveyor 6b at a position corresponding to the peak of the corrugated belt-shaped elastic sheet 21
7 is provided with an auxiliary lug 26 and a foliage cutting conveyor 6b.
And the lug 25 and the auxiliary lug 26 always have the same phase in synchronization with each other, so that the root of the radish is mounted on the valley of the corrugated belt-shaped elastic sheet 21 and Of the radish is received in contact with the auxiliary lug 26, the pressing force when cutting the radish foliage by the cutter 7 can be received by the lug 25 and the auxiliary lug 26, and the radish does not fall down from the conveyor 6 In addition, since the posture of the radish at the time of cutting the foliage is stabilized, the cutting performance in cutting the foliage is improved.

As shown in the plan view of the root crop harvesting assisting machine 1 of FIG. 1 and FIG. 12 (a side view taken along the line NN of FIG. 1), the two tail wheels 30, 30 are respectively A configuration including an axle 32 penetrating the tire 31 and a U-shaped bracket 33 rotatably supporting the axle 32 may be adopted. The tail wheel 30 has a lower surface in contact with the ground to bear a part of the load acting on the vehicle body, thereby reducing the load on the crawler 2 and acting to increase the stability of the vehicle body 3 in the front-rear direction. .

The U-shaped bracket 33 is rotatably mounted on the vehicle body 3, and the angle of rotation of the U-shaped bracket 33 can be remotely controlled by a cylinder switch 39 provided in the driver's seat 5. That is, the U-shaped bracket 33 has a rotation bearing tube 34 in a plane perpendicular to the axle 32 and passing through the center of the tire 31 and above the axle 32, and the tube 34 is fixed to the vehicle body 3 and fixed to the vehicle body 3. The left and right rear portions are rotatably and irremovably loosely fitted to an axle 38 protruding rearward in the horizontal direction. Further, a plate 35 is fixed to an upper portion of the tube 34. Tube 34 of bracket 33
Is connected by a connecting rod 36 to a plate 35 fixed to the plate.

The hydraulic pressure of the connecting rod 36 is controlled by operating a cylinder switch 39 on the driver's seat 5 to expand and contract the hydraulic cylinder 37. The connecting rod 36 is driven by the rod of the hydraulic cylinder 37, and the U-shaped bracket 33 is moved. It is a configuration that rotates.

Accordingly, the tail wheels 30, 30 can be operated so as to simultaneously rotate in the same direction. For this reason, when the tail wheel 30 that normally touches the ground is to be turned by the operation of the cylinder switch 39 of the driver's seat 5 when the root crop harvesting auxiliary machine 1 is to be turned at the end point of the field or the like,
The tail wheel 30 is a rotating bearing tube 3 above the axle 31.
4, the lower surface of the tail wheel 30 rises away from the ground as the rotation angle increases, and a distance L (FIG. 2) is formed between the tail wheel 30 and the ground. Even if it is present, it does not interfere with the tail wheel 30, and the turning of the root crop assistant 1 can be performed extremely smoothly.

As shown in the plan view of the root crop harvesting auxiliary machine 1 in FIG. 11 and FIG. 12 (side view in the direction of the arrows OO in FIG. 11), the two tail wheels 40, 40 A configuration including an axle 42 penetrating the tire 41 and a U-shaped bracket 43 for rotatably supporting the axle 42 may be adopted. The U-shaped bracket 43 is also rotatably attached to the vehicle body 3, and the rotation angle of the bracket 43 can be remotely controlled by a motor drive switch (not shown) provided on the driver's seat 5.

That is, the bracket 43 has a rotating shaft 44 in a plane perpendicular to the axle 41 and passing through the center of the tire 41 and above the axle 41, and the rotating shaft 44 is horizontal at the rear left and right of the vehicle body 3. Is rotatably and undetachably loosely fitted to a bearing 44a drilled in the direction, and a plate 45 is fixed to an upper portion of the rotating shaft 44.
Is connected to the plate 45 of the bracket 41 by a connecting rod 46, and the electric motor 47 is rotationally driven by the operation of a motor drive switch (not shown) of the driver's seat 5, and this rotational motion is transmitted through bevel gears 48, 48. The rotation is transmitted to one of the rotation shafts 44, and the rotation is transmitted to the other rotation shaft 44 via the plate 45 and the connecting rod 46 of the rotation shaft 44. Since the 43, 43 are driven to rotate, the tail wheels 40, 40 can be operated so as to simultaneously rotate in the same direction.

Thus, in the root vegetable harvesting assisting machine 1 shown in FIGS. 11 and 12, the tail wheel 40 is normally in contact with the ground, and when the root vegetable harvesting assisting machine 1 is to be turned at the end point of a field or the like, When the tail wheel 40 is rotated, the lower surface of the tail wheel 40 rises away from the ground, so that a distance L is formed between the tail wheel 40 and the ground. Therefore, turning of the root crop harvesting auxiliary machine 1 can be performed extremely smoothly.

As an embodiment of the present invention, the following configuration can be adopted by improving the conventional technique shown in FIG. That is, as shown in FIG. 15, conventionally, the harvest assisting machine 1 that assists in harvesting cabbage, radish, and the like attaches a work seat 50 via a mounting bracket 51 in front of a vehicle body 3 supported by crawlers or wheels 2, An operator who performs the harvesting work sits on the work seat 50 and cuts the root of a cabbage or the like or pulls out a radish or the like to perform the harvesting work. The use of the harvesting assisting machine 1 saves labor for harvesting root crops and greatly improves the efficiency of the harvesting operation. However, the harvester takes a forward leaning posture as shown in FIG. He was in a very difficult posture.

Therefore, as shown in the side view of the work seat 52 of the harvest assistant machine 1 of FIG. 14 and the front view of the work seat 52 of FIG. Work seat 52 supported by mounting bracket 51 in front of 3
Is a substantially horizontal seat portion 52a, a chest pad portion 52b connected in front of the seat portion 52a and extending obliquely upward, and left and right sides of the connected portion are hollowed out so that a leg of a harvester can be easily inserted.
A configuration integrally formed as 2c and 52c can be adopted.

The seat portion 52a, the chest pad portion 52b, and the concave portion 52c all incorporate elastic soft synthetic rubber or the like as a core material, and the surface thereof is covered with a soft synthetic resin sheet, so that the harvester who is on the work seat 52 is flexible. It is desirable to be able to abut against.

Thus, the seat portion 5 of the crop assisting machine 1
Since the work seat 52 having the breast rest 52b connected to the work 2a is provided, as shown in FIG. 14, the harvester can weigh the weight of the seat 52a and the breast rest 5 even if he leans forward.
2b is held separately, so that the burden on the lower back unlike the conventional work is eliminated. In addition, since the working posture becomes easy, it is possible to perform a long harvesting operation, thereby contributing to improvement of the working environment, labor saving and efficiency improvement of the harvesting worker.

Also, as shown in FIGS.
2, a weight is dispersed and held between the seat portion 52a and the breast portion 52b so that no burden is applied to the waist as in the conventional work. Each time it is harvested, it is necessary to repeat the upper body posture between the forward bending and the upright posture, but by using the work seat 53 as shown in FIG. 16 and FIG. 19, the burden for the posture change can be reduced.

That is, FIGS. 16 and 17 show a fixed work seat 53a supported by the mounting bracket 51, a movable chest pad 53b, a fixed work seat 53a and a movable chest pad 53.
b, a hinge part 53c for swingably connecting the movable chest pad 53b, a spring part 53d for elastically pulling the movable breastplate 53b,
Post part 5 which is the point of application of the spring part 53d on the vehicle body side
3e shows the movable work seat 53 constituted by 3e.

When the harvester sits on the fixed seat 53a and cuts or pulls out the harvested material to harvest it, the chest member 53b is used to take a forward bent posture.
At this time, since the harvester's own weight can be utilized, the spring portion 53d can be easily extended and accumulated, and when the posture is returned after cutting or pulling out the crop, the spring portion 53d is used. It works so that you can easily wake up using the energy of the energy.

In this way, the posture change of the harvesting worker becomes extremely easy, and the load can be prevented from being concentrated on a specific part from the waist to the back of the harvesting worker. It also contributes to improving harvesting efficiency.

Although a coil spring has been exemplified as the spring portion 53d, the spring portion 53d is not limited to this, and may be of an elastic rubber type or a gas pressure built-in type. Further, as shown in FIG. Instead, for example, the same effect can be obtained even if the torsion coil spring is incorporated in the hinge portion 53c.

Conventionally, a harvesting assisting machine 1 for assisting in the harvesting of cabbage, radish and the like is provided with a work seat 50 via a mounting bracket 51 in front of a vehicle body 3 supported by crawlers or wheels 2.
The worker who attaches the harvesting work and performs
And cut the cabbage roots or pulled out the radishes to harvest. The use of the auxiliary harvesting machine 1 has reduced labor for harvesting root crops, and has significantly improved the efficiency of harvesting. However, the harvester needs to take a posture as shown in FIG. Although it is an extremely hard posture that places a burden on the waist of the harvesting worker, if the weight is distributed and held between the seat portion 52a and the breast portion 52b as shown in FIG. The burden on the waist is eliminated and the movable chest pad 53b is pulled by the spring 53d as shown in FIG. 16 so that the posture change can be made even if the harvester repeats the downward posture between the forward bending and the upright posture of the upper body. Although it is easier and the working environment is improved, the position of the feet of the harvester who is still sitting on the work seat, landing on the field or getting off the ground every time the posture of the upper body changes, It needs improvement because it is stable.

Therefore, the construction shown in FIGS. 18 and 19 schematically showing the operation of the harvester and the work seat 54 may be adopted. In this case, the fixed work seat 53a supported by the mounting bracket 51, the movable chest pad 53b, and the fixed work seat 53
a, a hinge 53c for swingably connecting the movable chest pad 53b to the movable chest pad 53b, a spring 53d for elastically pulling the movable chest pad 53b, a post 53e serving as a point of attachment of the spring 53d to the vehicle body, and a footrest. And a movable work seat 54 with a footrest constituted by the step 54a.

The harvester sits on the fixed seat 53a and presses the chest pad 53b with the chest during the harvesting operation. At this time, since the harvester's own weight can be used, the spring 53d can be easily extended and stored. Can be energized,
When the posture is returned after cutting or pulling out the crop, the body can be easily raised by using the energy stored in the spring portion 53d, and at the same time, the harvest worker can be placed on the foot rest 54a provided below the fixed work seat 53c. Since the shin part of the foot is placed, the position of the foot is stably maintained regardless of changes in the posture of the upper body, and the load is concentrated on a specific part from the waist to the back of the harvester Can be prevented.
In this way, the harvesting operation can be performed for a long time, which is effective in improving the efficiency of the harvesting operation.
