The power of the engine 10 is transmitted to the variable hydraulic pump 11a of the hydraulic stepless transmission 11, and the swash plate (not shown) of the variable hydraulic pump 11a is tilted by the speed change lever of the operation unit 9 to make the fixed hydraulic motor 11b. The power of the fixed-quantity hydraulic motor 11b is input to the traveling transmission device 12, and then the speed is arbitrarily changed to drive the traveling device 1.

On the same axis as the variable hydraulic motor 11a,
A work machine pump 14 having a different hydraulic pressure source from the hydraulic continuously variable transmission 11 is provided. The rotational force of the working machine pump 14 is transmitted to a working machine motor 16 by a hydraulic pipe 15, and the working machine motor 16 drives the transport device 3 and the cutter 8. To explain this configuration in detail, the driving force of the work machine motor 16 is first output to the shaft 17 to drive the fixed sprocket 18 of the shaft 17.

On the lower side of the main transport section 3a in the transport direction, a shaft 2
1a and a sprocket 21 fixed to the shaft 21a are provided on the left and right. A shaft 23 is provided on the upstream side of the main transport section 3a in the transport direction.
a and a sprocket 23 fixed to the shaft 23a are provided on the left and right. A chain 22 is wound between the sprockets 21 and 23, respectively. A sprocket 21 is fixed to an end of the shaft 21a.
A chain 19 is wound around the sprocket 18 on the sixth side.

A shaft 2 is provided on the lower side of the auxiliary transport section 3b in the transport direction.
A sprocket 24 is fixed to one end of the shaft 25a, and a chain 19 from the working machine pump 16 is wound around the shaft 25a. A sprocket 25 is fixed to the other end of the shaft 25a. A sprocket 26 is provided on the upstream side of the auxiliary transport section 3b in the transport direction, and a chain 29 is wound between the sprocket 26 and the sprocket 25 on the upstream side.

A chain 19 from the work machine motor 16 drives a counter sprocket 30, and the power transmitted to the counter sprocket 30 drives the cutter 8 via a shaft 30a, a sprocket 27, a chain 27a, and a sprocket 28. It is. When the harvesting operation is started by running the harvesting auxiliary machine A configured as described above,
Are pulled out from the field scene and the radish 6 is placed on the transport device 3. Then, the radish 6 is conveyed toward the container 7 on the undercarriage 2 side,
On the way, the foliage 6 b of the radish 6 is cut by the cutter 8. After that, the radish conveyed to the terminal end of the conveying device 3 is stored in the container 7 by the assistant 32. While performing such operations, the harvesting assisting machine A runs at an arbitrary speed.

FIG. 5 shows a structure in which the transfer device 3 is fixed so as not to move during the operation. Rotating shaft 4 of transfer device 3
The plate 34 is fixed to the
5 is fixed. Further, a cylinder 36 is fixed to the chassis 2. When the transfer device 3 is extended to one side of the undercarriage 2 and the tube 35 of the transfer device 3 comes above the tube 36 of the undercarriage 2,
The pin 37 is inserted into the cylinders 35 and 36. Thereby, the transport device 3 is stabilized.

As described above, as shown in FIGS. 1 to 3, the transporting device 3 projects to the left of the chassis 2 during the work, and therefore needs to be stored when traveling on the road.
This storage configuration will be described. FIG. 6 is a diagram showing the vicinity of the transport end of the transport device 3. A cover 39 is provided on the side of the transfer device 3 to cover both sides of the transfer device 3.
Below the support 9, a support 38 for connecting the cover 39 on both sides is formed. The rotating shaft 4 of the transport device 3 is fixed to the support 38. The undercarriage 2 has a rotating shaft 4.
The rod body 40 that fits with is fixed upward. The rotating shaft 40 is rotatably fitted to the rod 40. FIG. 3 shows a state in which the transport device 3 is rotated about the rotation shaft 4 by a two-dot chain line.

The rotating shaft 40 is provided in the vicinity of the transfer end of the transfer device 3. The reason for this is that when stored as indicated by the two-dot chain line in FIG.
This is because c is located more inside (container side). If the rotating shaft 4 is located on the upper side in the transport direction of the transport device 3, the side portion 3c of the auxiliary transport portion 3b will protrude outward when it is stored, which is dangerous when traveling on a road.

As described above, since the rotating shaft 4 is provided near the end of the transfer device 3, the vehicle can safely travel on the road. Further, the position of the rotating shaft 4 is
And near the auxiliary transport section 3b in plan view. Thereby, when the transport device 3 is stored, the side portion 3c of the auxiliary transport portion 3b is
It is closer to the harvesting auxiliary machine A side, that is, the container 7 side,
Since the protrusion to the side can be prevented, traveling on the road can be performed safely.

Further, the rotation shaft 4 is located near an intermediate portion of the crawler 1a of the traveling device 1 in the lateral width direction in the front view of FIG. Thereby, the transport device 3 can be stably supported. In particular, when the traveling device 1 travels in a soft field scene, it is possible to prevent the crawler 1a from sinking. Next, FIG. 8 will be described.

FIG. 8 is a rear view of the harvesting assisting machine A, showing a state in which the transporting device 3 is extended to the side. further,
The container 7 shows a state in which the harvested radish 6 is stored in about half. In such a state, the center of gravity of the harvesting assisting machine A is configured substantially near the middle of the tread of the traveling device 1. Further, the center of gravity when the inside of the container 7 is empty is about 2/5 from the left traveling device 1 (the side of the transport device 3) with respect to the tread of the traveling device 1,
When the inside of the container 7 is substantially full, the center of gravity is configured near the position of approximately 3/5 of the tread of the traveling device 1 from the left traveling device 1 (on the side of the transport device 3). That is, when the state in the container 7 is empty and when the container 7 is full, the position of the center of gravity exists in the tread of the traveling device 1 and the movement of the center of gravity is suppressed to a small extent. Thereby, when the harvest auxiliary machine A travels in the field, it is possible to prevent the traveling performance, in particular, the straightness, from being impaired, and to prevent a decrease in work efficiency.

Next, FIG. 9 will be described. This figure shows a state in which the transport device 3 is housed. Even when the transport device 3 is stored in this way, the transport device 3
Is supported only by the rotation shaft 4, so that the vibration during traveling on the road causes the conveyance device 3 to vibrate vertically in the vicinity of the free end opposite to the rotation shaft 4 of the conveyance device 3, and In some cases, it was damaged by contact with No. 2. Therefore, the transport device 3
The guard bar 40 is provided at an arbitrary position (it is better to be as close to the free end as possible). Thereby, even if the transport device 3 vibrates in the vertical direction, the guard rod 40 is
Therefore, the transport device 3 can be prevented from being damaged.
