  Next, the operation of the rhizome crop harvester which is one embodiment of the present invention will be described. The vehicle body 1 that can be driven by the operation of the operator sitting in the cockpit 2 drives the crawler device 1a and travels, and the operator operates the operation device 3 to activate the harvesting device 5. An operator who processes the harvest on the vehicle sits on the seat 5 in the traveling direction. In this embodiment, two left and right seats 5 are provided, and work by two people is possible.

  When the vehicle body 1 travels in the direction of the arrow A and the harvesting device 4 is operated, the root stem blade of the root stem crop C is moved while the root cutting blade 7 provided in the front portion of the pulling and conveying conveyor portion 6 swings back and forth. The soil in the vicinity of U is swelled and softened and cut below the hair root R. The foliage portion L of the rhizome crop C is guided by the foliage guide 13 and is pulled out between the opposing surfaces of the pair of left and right elastic endless belts 6a, 6a of the rotating pulling and conveying conveyor portion 6, and obliquely up and rearward while being pinched It is conveyed to.

  The rhizome crop C conveyed obliquely upward and rearward enters between the cutters 8a of the foliage cutting section 8 provided in the reverse direction and is cut into the foliage L and the rhizome U. The cut rhizome part U falls as it is and falls onto the belt conveyor which is the rhizome receiving part 9. The foliage portion L from which the underground stem portion U has been cut is conveyed obliquely upward, caught on the endless rotating chain 11 which is the leaflet 11, and dropped onto the leaflet chute 12 on the downstream side and discharged to the field.

  Since the underground stem U that has fallen on the underground stem receiving portion 9 moves slowly by the movement of the belt conveyor, the underground stem U that successively falls in the same place does not accumulate. The slowly moving rhizome part U is supplied and placed on the bucket 102 of the follicle cutting part 10 by two workers sitting on the seat 5 which is the riding part.

  Each underground stem portion U is placed on the bucket 102 with its orientation determined in order to place the hair root portion R in the central recess of the root placement plate 103 of the bucket 102 and the stem S remaining on the valve B on the auxiliary plate 104 side. In this state, when the chain conveyor 101 moves to reach the hair root cutting blade 10b, the stem S and the valve B are cut by the stem cutter 107, and the space between the hair root portion R and the valve B is cut by the hair root cutter 106. At this time, the hair root portion R is sandwiched between the hair root gripping chains 108 of the hair root gripping portion 10c before being cut by the hair root cutter 106, but the hair root gripping chain 108 is upstream in the plan view as shown in FIG. Since the downstream side is provided so as to gradually move away from the chain conveyor 101 of the bulb moving body 10a, the root portion R is pulled in the traveling direction of the traveling vehicle, so that the cutting is more reliable and the bottom surface of the valve B is rooted. The hair root portion R is cut at a position close to the bottom surface of the valve B because it is pulled toward the mounting plate 103 and approaches the hair root cutter 106.

  The valve B from which the stem S and the hair root portion R are cut is transported while being placed on the bucket 102 and is dropped and stored in the cut portion storage container 13 on the downstream side.

  Of the underground stem U that has fallen to the underground stem receiving portion 9, the underground stem U that was not taken by the operator during the movement of the belt conveyor is dropped and stored in the receiving portion storage container 14 located on the lower downstream side of the belt conveyor. The The untreated rhizome part U that has fallen into the receiving part storage container 14 may be processed by operating only the follicle treatment part 10 again after completion of the digging work, or in a different process of another time or another place. It is possible to remove hair roots and the like.

  The sheet sheet 20 is cut with the sheet cutter 20 and the uncut portion is embedded in the soil, so that the film sheet pressing member 30 is surely acted in the next step. Since the film sheet F is prevented from being lifted and the film sheet F is stretched, the sheet cutter 20 is not left uncut and the work can be performed efficiently.

  The present invention is preferably used in a harvesting machine for root vegetables such as carrots and radishes, and rhizome crops such as garlic, onion, and lily roots, and in particular, rhizome crops that are extracted and harvested from a field while running garlic by a traveling vehicle body. The present invention can be used even if the vehicle body 1 that can travel is a walking type harvester that does not have the cockpit 2.
