Then, by loosening the grip screw rod 29g, the parasol pillar stand 29c can freely rotate back and forth and right and left, and is fixed by tightening the grip screw rod 29g.

As shown in FIGS. 7 to 9, the parasol mounting seat 29 according to the third embodiment has a support arm 28 to which a clamp metal fitting 29j is connected, and the clamp metal fitting 29j clamps a ball portion 29k. A parasol pillar stand 29c is fixed on the ball portion 29k, a nut 29f is fixed on the outer side of the holding metal fitting 29j, and a grip screw rod 29g is provided which penetrates the holding metal fitting 29j via a spring washer and is screwed into the nut 29f. There is. Then, by loosening the grip screw rod 29g, the parasol pillar stand 29c can freely rotate in all directions such as front, rear, left and right, and is fixed by tightening the grip screw rod 29g.

The transmission 5 that receives power from the engine 4 to change gears is equipped with a hydraulic continuously variable transmission (HST) (not shown) that continuously changes gears. 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. Further, a brake device is provided in association with the differential device. When the steering lever is largely operated, the side clutch, the differential mechanism, and the brake are actuated to turn the aircraft into a super-sight turn.

Further, as described above, the excavation conveyor 10 is capable of continuously and stepwisely changing the moving speed thereof, which is combined with the stepless or stepwise traveling of the crawlers 3 and 3. Therefore, the mining work speed can be set freely. When the potato harvester 1 is not used, the digging conveyor device 6 rotates the digging conveyor device 6 as a whole around the rotating portion 10a, or as shown in FIG. It can be folded and rotated to the side of the machine for storage, and the front-rear length of the machine can be shortened so that it can be carried by loading it on the cargo bed of a light truck, or can be stored in a warehouse or the like, and the headland can be swung in a small area. I have to.

Next, the operation of the rice crop harvester 1 configured as described above will be described. The potato harvester 1 harvests the wheels 15 and 15 of the ridge-following device 14 when harvesting root vegetables such as sweet potato, potato, onion, beet, taro, konjac potato, ginseng, and rakkyo from the field. The target ridge is rolled to both shoulders, and the digging blade 9 of the digging conveyor device 6 is vertically moved by the hydraulic cylinder 11 to adjust the digging depth, and the forward movement of the machine digs the harvested product. The blade 9 is used for excavation, and the excavation conveyor 10 conveys the excavated soil along with the soil to lift it diagonally upward. 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.

Only the root vegetables in the harvested product discharged from the transport end of the digging conveyor 10 onto the selection conveyor device 19 are handrailed by the operator sitting on the operator boarding device 20 and the selecting operator boarding device 21. , 23, and picked up and stored in a container (container) mounted on the harvesting device 25. The soil and foreign matters remaining on the sorting conveyor device 19 are dropped from the end of the transportation to the field through the space 24. An operator sitting on the operator boarding device 20 and the selecting operator boarding device 21 is prevented from being directly exposed to the sunlight or rain by the parasol 30, but when the direction of the sunlight or the direction of rain changes. By loosening the grip screw rod 29g, the parasol pillar stand 29c can freely rotate back and forth and right and left, and the grip screw rod 29g can be fixed by tightening.

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 harvesting device 25, the front-rear, left-right balance of the machine body 2 is improved, workability and work accuracy are improved, and the runnability of the machine body 2 is improved. The turning performance and stability are improved. In addition, since the traveling device (crawler 3, 3) is configured to be capable of super-spinning, and the transmission 5 is disposed in the central portion on the front side of the airframe, when the airframe 2 makes a super-spinning turn, You can turn in a good balance in any direction. Therefore, the crawlers 3 and 3 do not attract the soil in the field greatly.

In front of the digging conveyor device 6, there is provided a ridge following 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 to 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 worker sitting on the worker boarding device 20 can spend most of the time on the sorting work except for the operation of the machine body steering operation at the ridge of the ridge to be harvested. 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 at a small turning radius together with the super-field turning.

In addition to the potato harvesting work, the potato harvester 1 of the present invention is also used for harvesting abandoned empty cans, empty bottles, wood chips, etc., for example, on the coast or dunes. You can 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.
