The power transmission is engaged and disengaged via a side clutch and a differential device so that the crawlers 3 and 3 can be continuously and continuously varied. Then, when the steering lever is largely operated, the side clutch and the differential mechanism are operated to spin the aircraft.

Further, as described above, the excavation conveyor 10 can adjust its moving speed to stepless or stepped, and this can be combined with stepless or stepped running of the crawlers 3, 3. Thus, the digging work speed can be freely set. When the potato harvester 1 is not used, the digging conveyor device 6 rotates the entire digging conveyor device 6 around the rotating portion 10a, or folds the tip side portion as shown in FIG. It is rotated to the side of the machine to be stored, and the front and rear length of the machine is shortened so that it can be loaded on a truck bed for transportation and can be stored in a warehouse or the like, and it is possible to rotate headland in a small area. .

Next, the operation of the potato harvester 1 configured as described above will be described. The potato harvester 1, for example, when harvesting potatoes from the field, rolls the wheels 15 and 15 of the ridge-following device 14 onto the inclined both shoulders of the ridge to be harvested, and the digging blade of the digging conveyor device 6 is used. 9 is adjusted up and down by the hydraulic cylinder 11 to adjust the digging depth, the harvested product is digged by the digging blade 9 as the machine advances, and the mine is conveyed by the digging conveyor 10 along with the soil to tilt the machine. Lift up. During this transportation, soil falls from between the link rods, and a worker sitting on the auxiliary worker boarding device 18 performs a pretreatment to remove vines, foliage, large soil blocks, stones, etc. other than root vegetables.

A seat 20 b of the operator boarding device 20 and a seat 21 b of the sorting operator boarding device 21 so that potatoes among the harvested products discharged from the transport end of the digging conveyor 10 to the second conveyor 19 are left. An operator who sits at or stands up and sorts over the handrails 23, 23, conveys them by the movement of the second conveyor 19, and is conveyed from the conveyance end to the third conveyor 33 via the delivery body 31. In the third conveyor 33, small potatoes are dropped while the potatoes are supported and conveyed by the ropes 36, 36, and the horizontal bar, and are stored in the small ball storage container 32a below. The large-sized potatoes are accommodated in a medium / large-diameter container 32, which is obliquely placed on the container support frame 28 in front of the transport end, via a rubber drip 40.

When the operator or the operator works while sitting on the seats 20b and 21b, the height of the seat is adjusted by replacing the support pins 45b and 50b according to the physique of the operator or the operator. For the work direction, the seats 49, 55, 55a can be easily rotated to the optimum work position by turning the seats 49, 55, 55a by the turning arm 44, the chair support rod 46, the turning support column 50, the chair support pipe 51, etc. You can Further, when the worker or the pilot does not sit on the seat 20b and the seat 21b and works in a standing posture, the angle of the seats 55 and 55a should be adjusted according to the physique and the working posture of the worker or the pilot. It is possible to perform the work easily by replacing the seats 58 with the seats 55 and 55a as waist rests and supporting the body.

In the medium / large size container 32 placed on the container support frame 28, the light load spring 29 a of the support device 29 is first compressed according to the weight of the harvested products sequentially received from the third conveyor 33. As a result, the telescopic cylinder 30 is contracted, and along with this, the container support frame 28 rotates clockwise about the pin 28a in FIGS. 6 and 8, and the middle / large-lens container 32 also rotates. When the weight of the harvested product in the medium / large-sized container 32 reaches a certain weight, the telescopic cylinder 30 comes into contact with the upper surface of the heavy load spring 29b, and thereafter, the light load spring 29a and the heavy load spring having a larger spring constant than this. It will be supported by both 29b. Then, when the container support frame 28 overlaps the container mounting table 25 and the support column 38 and the container 32b is supported substantially horizontally, the container support frame 28 is held by the holding body 30b.

At this time, the medium and large-sized potatoes are almost full in the container 32b, the traveling of the aircraft is stopped temporarily, and one of the workers working on the boarding devices 20 and 21 operates the container 32b on the container 32b. The empty container 32c mounted on the container mounting table 39 is mounted on the container support frame 28 by sliding it on the mounting table 25 and moving it. Then, when the container support frame 28 is pulled so as to release the holding of the container support frame 28 by the holding body 30b, the elastic force of the light load spring 29a and the heavy load spring 29b of the support device 29 causes the container support frame 28 to move. 28 rotates counterclockwise around the pin, and the empty container 32c returns to the position for accommodating medium and large ball potatoes, and the harvesting work is restarted.

Here, the potato harvester 1 has an engine 4, a transmission 5, and an operation unit (operation system) 7 arranged in front of the crawlers (traveling devices) 3, 3 and a worker boarding device in the rear thereof. By disposing 20, the sorting operator boarding device 21 and the container mounting table 25, the front-rear and left-right balance of the machine body 2 is improved, workability and work accuracy are improved, and the traveling and turning of the machine body 2 are improved. Performance and stability are improved. In addition, since the traveling devices (crawler 3, 3) are configured to be able to spin-turn and the transmission 5 is arranged in the central portion on the front side of the machine body, the machine body 2 can be rotated in either the left or right direction when spin-turning. Can also turn in a balanced manner. Therefore, the crawlers 3 and 3 do not greatly pull the soil in the field.

In front of the digging conveyor device 6, there is provided a ridge follower device 14 that follows the movement of the machine body along the length direction of the ridge to be harvested, and a pair of ridges to be rolled on the inclined shoulders of the ridge to be harvested. Since the wheels 15 are provided so as to face each other so as to be vertically adjustable and horizontally adjustable with respect to the digging conveyor device 6, both wheels 15 accurately follow the ridge to be harvested and automatically operate the machine. Then, the digging conveyor device 6 automatically digs and conveys. Therefore, the operator sitting on the operator boarding device 20 can spend most of his / her time on the sorting work except for the operation of the machine body steering operation at the ridge of the ridge to be harvested. Further, when the headland is turned at the end of the field, the excavation conveyor device 6 is folded by the hydraulic cylinder 12 so that the crawlers 3 and 3 can be turned and rotated with a small turning radius.

The potato harvester 1 of the present invention is used not only for the potato harvesting work but also for the work of collecting the empty cans, empty bottles, wood chips, etc., which are left on the coast or sand dunes, for example. be able to. In that case, the ridge-following device 14 may be removed or it may be made to function as a device for adjusting the digging depth of the digging blade 9. Further, the second conveyor 19, the transfer body 31, and the third sorting conveyor 33 can be used not only as the potato harvester 1 but also as a stationary sorting device.
