Therefore, it is prevented that the traveling device (28) bites a stone or a lump and the harvesting operation is stopped and the harvesting operation is stopped, so that the work efficiency is improved and the number of times of maintenance can be reduced. Is reduced.

  Further, even if the traveling device (28) steps on the leaves or weeds, it is discharged from the space to the field before it gets tangled. Therefore, the leaves and weeds are entangled with the traveling device (28) and the operation of the traveling device (28) is performed. This improves the work efficiency and improves the maintainability because it can be easily taken even if the leaves or weeds get entangled.

And since a traveling apparatus (28) can be comprised only by attaching a front drive wheel (27) and a rear drive wheel (26) to a transmission mechanism (17), a body structure is simplified.
According to the invention described in claim 3, in addition to the effect of the invention described in claim 1, since the traveling device (28) is configured by the endless track crawler traveling device (51), the ground contact area is increased and stabilized. Since crops can be harvested in a posture, the working posture of the aircraft is stable and the working efficiency is improved.

  According to invention of Claim 4, when the drawing conveyance apparatus (66) pulls out a crop, it pulls out by having arrange | positioned the drawing conveyance start end part of the drawing conveyance apparatus (66) above the front part of the traveling apparatus (28). Even if the force is applied to the front side of the aircraft, the aircraft can be prevented from tilting forward, so that the working posture of the aircraft is stabilized, the work efficiency is improved, and the safety of work is improved.

  Further, the front side of the left and right traveling devices 28 and 28 are positioned below the left and right driven pulleys 54 and 54 provided at the front end portion of the pulling and conveying device 66, so that the force for pulling the stems and leaves K of the ginger G is on the front side of the body. Even when concentrated on the vehicle, the force that the left and right traveling devices 28, 28 disperse is prevented from tilting forward, and the traveling posture and the harvesting work posture are not disturbed. Since it is prevented that the worker falls over or falls out of balance, the safety of work is improved.

Next, the leaf discharging part E will be described.
A drive pulley 81 is attached to the upper part of the drive rotation shaft 55 on the left side of the machine body, and a cover frame 82L is attached to the upper end of the left and right drive rotation shaft 55. Then, the driven pulley 83 and the idle pulley 84 are rotatably mounted on the outer side of the cover frame 82L, and the leaflet belt 85 is wound around the driven pulley 83, the idle pulley 84, and the drive pulley 81. A tension arm 87 having a tension pulley 86 rotatably attached thereto is attached to the cover frame 82L, and the tension pulley 86 presses the inside of the non-clamping action portion of the leaflet belt 85. Further, the driven rotation shaft 88 is attached to the driven pulley 83, and the second cutting blade 89 is attached to the lower end portion of the driven rotation shaft 88.

  Further, a drive pulley 90 is attached to the upper part of the drive rotation shaft 55 on the right side of the machine body, and a cover frame 82R is attached to the upper end of the left and right drive rotation shaft 55. Further, a driven pulley 91 and a first idle pulley 92 are rotatably mounted on the outside of the cover frame 82R, and a second idle pulley 93 is rotatably mounted on the front side of the body. Then, a belt 94 is wound around the driven pulley 91, the first idle pulley 92, the second idle pulley 93, and the drive pulley 90. Further, a tension arm 96 having a tension pulley 95 rotatably attached thereto is attached to the cover frame 82R, and the tension pulley 95 is pressed to the outside of the leaflet belt 94. Further, by attaching the driven rotation shaft 97 to the driven pulley 91 and attaching the second cutting blade 98 to the lower end portion of the driven rotation shaft 97, the leaf discharging device 99 is configured.

  As described above, the pulling / conveying device 66 and the leaf discharging device 99 are both driven by receiving the driving force from the left and right second driven sprockets 12 and 12 via the left and right driving rotary shafts 55 and 55, and therefore are components constituting the machine body. The number can be reduced and the cost can be reduced.

  Moreover, since the left and right second cutting blades 89 and 98 are attached to the conveying terminal portion of the leaf discharging device 99, the leaves and leaves K are cut into short pieces and then discharged to the field, so that the leaves and leaves K are entangled with the body. It can be prevented from stopping and appropriate farming can be performed.

  When the traveling device 28 is the crawler traveling device 51, the crawler traveling device 51 is disposed below the discharge unit of the leaf discharging device 99, so that the discharged leaves are discharged to the field while being transported forward by the crawler traveling device 51. Since the defoliation is prevented from getting entangled with the airframe, the operation of the airframe is prevented from being stopped by the defoliation, and the work efficiency is improved. Since it can be omitted, the labor of the operator is reduced.
