[0001]

[Industrial applications]

 This proposal concerns a sugarcane reaper that is planted in a sugarcane field.

[0002]

[Prior Art]

 Conventionally, the harvesting of sugarcanes that were planted in a bundle on a ridge was done by cutting with a single address, which required manual labor and forced heavy labor.

Further, there is a problem that a hard stump remains on the upper surface of the ridge during the above-mentioned mowing, which hinders the plowing of the ridge.

[0004]

[Problems to be solved by the device]

 This project aims to obtain a sugarcane reaper that does not leave a stump on the ridge by cutting the sugarcane planted in a bundle in the ridge of the sugarcane field from the root in the ground below the upper surface of the ridge by mechanical force.

[Action]

 In the present proposal, the crawler tracks 23, 23 of the crawler 1 are supported on the middle side of the ridge 21 as shown in FIG. 9, and run along the ridge 21 so that the lower surface of the vehicle body 2 does not contact the upper surface of the ridge 21. Then, the boom 4 and the arm 5 are lowered forward to insert the base portion of the sugarcane bundle 22 'shown in FIG. 7 between the opened clip claws 14, 14 and then the clip claws 14, 14 are closed as shown in FIG. The bundle of sugar cane 22 'is clamped, and in that state, the boom 4 and the arm 5 are raised to the position indicated by the solid line in FIG. 1, and further the boom 4 and the arm 5 are rotated to the position indicated by the phantom line in FIG. By moving forward, the cutting blade 16 is advanced in the ground along the upper surface of the ridge 21. The root of the sugar cane bundle 22 'can then be cut inside the ridge 21.

In this state, the support 13 is rotated by 90 degrees around the drive rotation shaft 12 to rotate the sandwiching claws 14, 14 by 90 degrees, so that the standing sugarcane bundle 22 'is formed laterally. , The vehicle body 2 is rotated to lower the boom 4 and the arm 5 to lay the bundle 22 'laterally to the side of the ridge 21 (FIG. 10), and open the sandwiching claws 14 and 14 to perform the above-described operation. Repeatedly, the sugarcane bundle 22 'can be trimmed orderly.

By extending the elevating arm 15 from the position shown by the solid line in FIG. 3 to the position shown by the phantom line in FIG. 3, the sugarcane bundle 22 ′ held by the sandwiching claws 14, 14 can be cut and cut without advancing the vehicle body 2.

The rotary blade 16 for mowing can be rotated by an output shaft 18 of a drive motor 17 mounted on a rear portion 2 ′ of the vehicle body 2 through an input shaft 19 of the rotary blade 16. The invention can be applied to lifting and lowering and stretching in the front-rear direction, and the prime mover 17 can be provided on the vehicle body 2 without hindering the rotation of the rotating machine base 3.

Move up and down around the horizontal pin 6. A rotatable arm 5 is pivotally supported by a horizontal pin 7 on the tip of the boom 4, and can be rotated about the horizontal pin 7 by a cylinder 29.

A work machine 10 is pivotally supported by a horizontal pin 8 on the tip of the arm 5, and can be rotated around the horizontal pin 8 by a cylinder 30 to form a small work crawler 1. Is.

The working machine 10 includes a support tool 13 and a support tool which are pivotally supported by the horizontal pin 8 at the tip of the arm 5 and which are rotated by a drive rotary shaft 12 orthogonal to the horizontal pin 8 at the front end of the metal tool 11. 13 is formed by pinching claws 14, 14 pivotally supported by pins 31, 31 to open and close. The drive rotary shaft 12 is rotated by a hydraulic motor 32, and an operating arm 33 provided on one side of the pinching claws 14, 14. The small cylinder 34 is connected to the pin 31, and the gears 35, 35 provided on the pins 31, 31 mesh with each other, whereby the pinch claws 14, 14 can be opened and closed by the operation of the small cylinder 34.

At the front end of the vehicle body 2, a base end of a forward elevating arm 15 is rotatably supported by a horizontal pin 9, and a cylinder 36 can rotate the horizontal pin 9 up and down. A gear casing 37 is provided at the front end of the elevating arm 15, and a mowing rotary blade 16 is provided on an upright output shaft 38 protruding from the lower surface of the gear casing 37.

The elevating arm 15 is fitted with a sliding arm 15 ′ that can be expanded and contracted forward by a cylinder 39, and a gear frame 37 is tilted around a horizontal shaft 41 on a support frame 40 provided at the tip of the sliding arm 15 ′. The tilt can be adjusted freely. The output shaft 18 of the driving prime mover 17 is connected to the rearward input shaft 19 of the gear housing 37 via a retractable universal joint 20.

[Effect of the device]

 Since the present plan is configured as described above, not only can a plurality of hard sugarcanes 22 planted on the ridges 21 be cut in a bundle at a time without requiring human power, but also stumps can be cut on the upper surface of the ridges 21. There is an effect that the root can be cut in the ground directly under the upper surface of the ridge 21 without leaving. Further, since the rotary cutting blade 16 can be expanded and contracted in the front-rear direction, it can be cut relatively in front of the vehicle body 2. Therefore, the uncut sheep cane 22 already lying on the ridge 21 is bundled and cut. It's easy. Further, since the drive motor 17 for driving the rotary blade 16 is provided at the rear end portion 2'of the vehicle body 2, the rotary motion of the rotary machine base 3 mounted on the vehicle body 2 can be performed without any trouble, and the relatively small sugar cane cutting machine is provided. It's a good opportunity.
