[0020]
Next, the operation of the thigh harvesting machine 1 including the multi-film peeling and collecting device 28 configured as described above will be described.
For example, when harvesting sweet potatoes cultivated by laying a multi-film from a field, the potato harvester 1 first processes the foliage (vines) of the sweet potatoes and removes the wheels 13, 13 of the ridge following device 12 to the harvest target. The multi-film F is peeled off from the end of the ridge to be harvested by human power, and the leading end of the multi-film F is wound on the winding drum 30 of the multi-film peeling and collecting device 28 along the rotation direction. Wrap. The digging depth of the digging blade 9 of the digging conveyor device 6 is adjusted, and the machine body is advanced. Then, the multi-film F is vertically swung by the guide rollers 37 passing between the guide rods 38, 38, and is sequentially wound on the winding drum 30 while being peeled off from the field. Although the rotation speed of the winding drum 30 and the moving speed of the harvester 1 are substantially synchronized, when the rotating portion of the winding drum 30 is overloaded, the power is shut off by the torque limiter 34. By passing between the guide rods 38, 38, the multi-film F is stably wound on the winding drum 30 even if the wind blows from the rear side as a tailwind as shown in FIG.
[0021]
The digging blade 9 of the harvester 1 digs up the ridge to be harvested in the vertical direction, and the digged crop is conveyed obliquely upward and rearward of the machine body by the bar conveyor 10 and the slats of the digging conveyor device 6. Even if the upper portion of the ridge dug by the digging blade 9 may fall to the ridge groove side, it is guided by the rake body 17 and brought to the conveyor 10. Then, the crops conveyed obliquely upward and rearward by the conveyor 10 and the slats that rotate endlessly are brought to the sorting conveyor 19 from the transport end, where they are sorted by the operator, and the sorted crops are It is mounted on the rear container mounting table 20 and accommodated in the container.
[0022]
When the amount of the multi-film F wound on the winding drum 30 becomes almost full with respect to the side plate 30c, the traveling of the harvester 1 is stopped to stop the harvesting operation, and the multi-film F is moved near the side plate 30c. The outer periphery of the cut and wound multi-film F is bound by the multi-film binding mechanism 39. Then, as shown in FIG. 6, the support frame 31a is tilted, the take-up drum 30 is taken out from the support frame 31, and one side plate 30c is taken out from the rotating shaft 30a and the take-up shaft 30b. Then, the multi-film F wound around the winding shaft 30b and bound at the outer peripheral portion is easily taken out when the winding shaft 30b is bent at one end in the small diameter direction as shown in FIG. Then, the side plate 30c is inserted into the rotating shaft 30a and the winding shaft 30b to assemble the winding drum 30, and supported between the support frames 31, 31a, and the cut end of the multi-film F is wound around the winding drum 30. The harvesting operation of the harvester 1 is restarted.
[0023]
In the bar conveyer 10 of the harvester 1, while the harvested material is conveyed with the soil and lifted and conveyed diagonally upward, the soil fell between the bars of the bar conveyer 10 and sat on the auxiliary worker seat 16. An operator performs a pretreatment for removing vines, foliage, large earth mass, stones and the like other than potatoes. The crop discharged from the transporting end of the bar conveyor 10 onto the sorting conveyor 19 is sorted by an operator sitting on the operator's seat 22 and the sorting operator's seat 24 and placed on the rear container mounting table 20. Housed in a designated container.
[0024]
Here, the potato harvester 1 includes the engine 4, the transmission 5, the operation unit (operation system) 7, and the seats around the crawlers (traveling devices) 3 and 3, the excavating conveyor device 6, and the sorting conveyor 19. By arranging 16, 22, 24 and the container mounting tables 18, 20, 27 almost symmetrically, the front-rear, left-right balance of the body 2 is good, workability and work accuracy are improved, and the runnability of the body 2 is improved. , Turning performance and stability are improved. In addition, the traveling device (crawlers 3 and 3) is configured to be capable of pivoting or pivoting, and the transmission 5 is disposed at the center of the front side of the fuselage. The player can turn in a balanced manner in either the left or right direction. Therefore, the crawlers 3 and 3 do not greatly scrape the soil of the field.
[0025]
A ridge following device 12 is provided in front of the digging conveyor device 6 for following along with the movement of the machine along the length direction of the ridge to be harvested, and a pair of wheels 13 which are in contact with the inclined shoulders of the ridge to be harvested are opposed to each other. It is provided so as to be vertically adjustable and horizontally adjustable with respect to the digging conveyor device 6, and the wheel 13 automatically follows the ridge to be harvested to automatically steer the machine body. Automatic excavation and transport are performed. Therefore, the worker sitting on the worker's seat 22 can spend most of the time on the sorting work except for the operation of the body steering at the ridge end of the ridge to be harvested. When the headland turning is performed at the field end, the excavating conveyor device 6 can be turned with a small turning radius together with the sharp turning of the crawlers 3 by folding the excavating conveyor device 6. When storing the potato harvester 1 in a warehouse or moving on a road, the length of the machine can be shortened by setting the rear container mounting table 20 in the storage state. When the multi-film peeling and collecting device 28 is not used, it may be removed from the potato harvester 1.
