[0003] Further, there are cases where it is desired to change the tillage depth depending on the purpose of tillage. However, since the turning radius of the conventional tillage claw is not changed, it is necessary to replace the tillage claw every time when it is desired to change the tillage depth. .

Means for Solving the Problems To achieve the above object, the technical means adopted by the present invention is to dispose a tilling shaft in the left and right direction of the body, and rotate the tilling shaft in the left and right direction of the body. The tilling claw is attached to the tilling shaft side by a spring as much as possible, and the tilling claw is tilted to the tilling shaft side by the spring force when the tilling shaft is not rotating, and the tilling shaft rotates. The tilling claw is configured to rotate in the direction perpendicular to the tilling axis by the centrifugal force accompanying,
The feature is that the rotation radius of the tilling claw can be changed according to the rotation speed of the tilling shaft.

[0006] In the present specification, the turning radius of the tilling nail refers to the protrusion dimension of the tilling nail in a direction perpendicular to the tilling axis. Since the tilling claw is opened and closed by centrifugal force, when the tilling is started at a low speed, the turning radius of the tilling claw is small and the tilling resistance is small, so that the dashing of the machine body can be prevented well. It is considered that not all tilling claws need to be rotatable from the viewpoint of preventing dashing of the airframe.

[0007] Since the rotation radius of the tilling claw can be changed by the rotation speed of the tilling shaft, the tilling depth can be freely changed by the rotation speed of the tilling shaft. However,
In some cases, the tilling nails may swing due to the earth pressure, but this is relative to the hardness of the field,
If the soil is soft, it can be tilled with the selected turning radius.

Conventionally, there is a swingable tilling claw as a residual tilling treatment device. However, a tilling claw is mounted on a tilling shaft so as to be rotatable in the left-right direction of the machine body, and the cultivating claw is fixed by a spring. The configuration "biased to the side" is completely new.

In FIG. 2, a twist of approximately 90 degrees is applied to the base end of the straight flat portion 1a, so that the lower end of the straight flat portion 1a is horizontal with respect to the tilling shaft 2. 5 is attached. By doing so, the tilling claw 1 can be attached and detached from the circumferential direction of the tilling shaft 2, and the bolt 6a, the nut 6b
The direction of tightening and loosening is different from the rotation direction of the tilling shaft 2 by 90 degrees, so that the work can be easily performed even if the pipe 3 is not fixed to the tilling shaft 2. Therefore, the tightening and loosening directions of the bolt 6a and the nut 6b at the time of attaching and detaching the tilling claw 1 were the length direction of the tilling shaft 2.
The conventional problem that it is difficult to work without fixing the pipe 3 can be solved.
