Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a structure for preventing grass straw from wrapping around a rotary case in a rotary part.

(B) Conventional technology and its problems Conventionally, in the rotary section, a rotary shaft protruding from a rotary case is connected with a hatchet claw, and cultivation is performed by rotating the hatchet claw. The grass straw wrapped around the rotary case,
Rotation of the machete claw was obstructed, and it was difficult to remove the entangled grass straw.

(c) Means for solving the problem Therefore, in the present invention, the left and right rotary shafts are installed in the left and right directions, respectively, from the lower left and right sides of the rotary case, which is installed in the center of the fuselage with an incline of high front and low rear. The machete claws are connected to the circumferential surface of both shafts so that the machete claws face the plowing surface and perform tilling from the front to the rear in conjunction with the rotation of both shafts. In the center drive type rotary part, which has a rotary cover that covers just above the machete claw, a straw-wrapped rod is raised from the bottom of the rotary case, and the upper end of the straw-wrapped rod is covered with a rotary cover. A space that is approximately V-shaped in side view is formed between the straw-wrapped rod and the rear side of the rotary case, and the space allows the rotary to be inserted from behind the straw-wrapped rod. The straw caught in the machete claw that rotates towards the case side,
It is an object of the present invention to provide a structure for preventing grass straw from being wrapped around a rotary case in a rotary part which is formed by wrapping around the circumferential surface of a straw-wrapped rod.

(d) Example If the example of the present invention is detailed based on the drawings,
A shows an agricultural tractor, and B shows a rotary part.Agricultural tractor A has a motor casing 1 at the front, a driver's seat 2 at the rear, and a lift arm at the bottom of the driver's seat 2 on the upper part of the body frame a. 3, and at the lower part of the body frame a, front wheels 5 are arranged on both sides of the front part, and rear wheels 6 are arranged on both sides of the rear part.

In addition, the rotary part B is provided with a tilling part 8 on the front lower side of the depth adjusting frame 7 installed on the upper side of the fuselage b, and a tail wheel 9 on the rear lower side, and the front end of the frame 7 It is connected to the rear of the tractor A via a lift arm 3.

The tilling section 8 is of a center drive type in which a rotary case 9 housing an interlocking shaft therein is provided at the center of the front side of the body b, and the case 9 is inclined with a high front and a low rear.

In addition, left and right rotary shafts 10 and 11 are provided on both sides of the lower part of the rotary case 9 toward the left and right sides.
are provided protrudingly, and a plurality of machete claws 12 are provided in succession around both shafts 10 and 11, respectively.

In addition, on the top of the rotary case 9, there is a machete claw 1.
A rotary cover 13 is provided to cover directly above the rotary cover 2.

A straw-wrapped rod 14 is interposed between the lower part of the rotary case 9 and the rotary cover 13, and the straw-wrapped rod 14 has its lower end connected to the lower rear side surface 9' of the rotary case 9. , and the upper end extending upwardly in an upwardly extending manner is connected to the lower surface of the rotary cover 13, and a side view is formed between the straw-wrapped rod 14 and the rear surface 9' of the rotary case 9. A substantially V-shaped space S is formed.

In addition, the lower end support position of the grass straw wrapping rod 14 is provided at least on the rotation center side from the rotation locus of the tip of the hatchet claw 12, so that the forward tilling operation of the hatchet claw 12 (from the front to the rear toward the tilling surface) is performed. During the tilling operation), the grass straw rolled up by the machete claw 12 can be wrapped around the circumferential surface of the grass straw wrapping rod 14, so that the grass straw can be wrapped around the rotary case 9 as much as possible. It is configured so that it can be reduced.

Therefore, the straw caught in the machete claw 12 wraps around the straw wrapping rod 14 before reaching the rotary case 9, and can prevent the straw from being wrapped around the rotary case 9. The rotation of the claw 12 is not hindered, and the grass straw wrapped around the straw-wrapped rod 14 can be removed using a sickle or the like since there is a space around the straw-wrapped rod 14. It is easy to do. Further, by detachably attaching the grass straw wrapped rod 14, grass straw can be removed more efficiently. Furthermore, if the straw-wrapped rods 14 are arranged facing the front side of the rotary case 9 with a certain distance between them, even when the hatchet claws 12 are in reverse tillage mode,
Similar wrapping prevention is possible.

(E) Effect According to the present invention, the straw-wrapped rod is interposed upright between the lower part of the rotary case and the lower surface of the rotary cover, and the straw-wrapped rod is connected to the rear surface of the rotary case. Because of the space formed between them, the following effects occur.

In other words, the grass straw caught by the machete claw that rotates from behind the straw wrapping rod toward the rotary case side is easily wrapped around the circumferential surface of the grass straw wrapping rod.
The grass straw does not wrap around the rotary case located immediately in front of the rod, and therefore, it is possible to reliably prevent the grass straw from wrapping around the rotary case and the rotary shaft.

Moreover, since the rotary cover can be supported by the straw-wrapped rods, even if mud, etc. adheres to the bottom surface of the rotary cover, the rotary cover will be deformed due to the weight of the mud, etc. It is possible to prevent the occurrence of defects.

FIG. 2 is a front view of the main parts of the same example. A: agricultural tractor, B: rotary part, b: body, 9: rotary case, 10, 11: left and right rotary shafts, 12: machete claw, 13: rotary cover, 14: straw-wrapped rod.

Claims (1)

[Scope of Claim for Utility Model Registration] Left and right rotary shafts 10 and 11 are provided in the lower left and right sides of the rotary case 9, which is provided in the center of the body b so as to be inclined forwardly and rearwardly, so that left and right rotary shafts 10 and 11 project in the left and right directions, respectively. There are hatchet claws 1 on the circumference of the shafts 10 and 11.
2 are arranged in series so that the machete claw 12 operates to till the plowing surface from the front to the rear in conjunction with the rotation of both shafts 10 and 11. In the center drive type rotary part, which is provided with a rotary cover 13 that covers the rotary case 12 directly above, a straw-wrapped rod 14 is raised from the lower part of the rotary case 9, and the upper end of the straw-wrapped rod 14 is attached to the rotary section. A space S that is approximately V-shaped in side view is formed between the straw-wrapped rod 14 and the rear surface 9' of the rotary case 9, and is connected to the lower surface of the cover 13. The grass straw caught by the machete claw 12 rotating from behind the straw wrapping rod 14 toward the rotary case 9 side is
A structure for preventing grass straw from being wrapped around a rotary case in a rotary part which is made to wrap around the circumferential surface of a straw-wrapped rod 14.
