Also, crop dividers 3 and 3 are attached to the front in two rows in parallel from the vertical position and inclined backward from the vertical position, and base cutters 4 and 4 are arranged in the center of the rear in two rows inclined slightly forward from the vertical position to the front. Installed. At the lower end of the base cutter 4, there are provided rotary blades 5, 5 for cutting the root of the sugar cane while rotating.

Immediately after the base cutters 4, 4, pull-in rollers 6, 6 are arranged in upper and lower two stages. The leaf rollers 8 are arranged in a plurality of rows in upper and lower two stages. Immediately after the uppermost conveying roller 7, the chopping cutter 9 and the housing rotating device 1
0 is arranged.

At the rear of the cane harvester 1, a frame 11 for accommodating a bag for acne storage is attached at a position lower than the chopping cutter 9, and the mouth of the acne storage bag 12 is attached to the frame 11. . A suction port 15 of a suction device 14 is provided in a path from the chopping cutter 9 to the frame 11. The suction device 14 sucks a sugarcane trash 16 by suction force caused by rotation of a built-in suction fan 13. The cane 17 that is heavier than the trash 16 and cannot be sucked up by the suction device 14 falls into the acne storage bag 12 by its own weight. The frame 11 for mounting the storage bag can be moved up and down by a link mechanism 24 so that the cane 17 can be easily taken out. The suction device 14 has a discharge port 19 that opens toward the rear of the cane harvester.
In addition, one end of the chute 21 is attached by the attachment 20. The chute 21 is a tubular body having both ends opened, is made of net cloth, and has flexibility. The chute 21 has the opening 22 at the other end positioned near the ground.

On the other hand, the trash 16 having a relatively light weight is sucked up by the suction device 14, discharged from the outlet 19, and discharged into the chute 21. Trash 16 discharged into this chute 21
Is blown into the chute 21 by the blowing force associated with the rotation of the fan in the suction device 14, and is blown to the vicinity of the ground through the opening 22 at the other end of the chute. At this time, since the chute 21 has flexibility, the chute 21 is deformed by the blowing force of the fan 13 into a shape through which the trash 16 and the air can easily pass. Therefore, the trash can quickly pass through the deformed chute 21.
Further, since the chute 21 has flexibility, the other end of the chute 21 can be easily arranged at a desired position, and the trash 16 can be discharged to a desired ground position.

As described above, according to the present embodiment, the trash 16 is discharged to the ground without being scattered in the air by the chute 21 having one end attached to the discharge port 19. As a result, trash is scattered and scattered around the sugar cane field as in the past, or it is piled up on the cane harvester and contaminates the cane harvester,
It is possible to effectively prevent inconveniences such as a fire caused by the heat of the engine muffler of the cane harvester and a traffic accident such as car slippage caused by scattering on the road.

Further, the trash is the same as the shoot 21
Since the chute 21 is fixed to the cane harvester and the cane harvester is driven along the ridges of the sugar cane field, the trash can be discharged in a regular row between the ridges of the sugar cane field.
Therefore, the trash can be easily collected and easily used as compost or feed for livestock.

In the above embodiment, the chute 2
1 is made of net cloth, but may be formed of a nylon sheet or the like.

Further, the lower end of the chute 21 may be connected to a portion of the cane harvester 1 such as the frame 11 by a string or a wire so that the chute 21 does not blow away by wind.

Further, the discharge port 19 of the suction device 14 may be rotatable 180 degrees in the horizontal direction on the rear side, and the chute 21 may be rotatable together with the discharge port 19. Thereby, the shoot 2 which blows out the trash 16
The other end position of the first trash can be arranged in a wider range, and the trash 16 can be reliably discharged to a desired ground position.

Further, a trash loading-only accompanying vehicle may be run together with the cane harvester, and the trash may be discharged to the trash loading-only accompanying vehicle via the chute 21. Alternatively, a trash storage bag may be installed in the cane harvester, and the trash may be discharged into the trash storage bag.
