Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a tilling claw that is used by being attached to a tilling shaft that is provided obliquely in a horizontal plane with respect to the direction in which the machine moves.

[Conventional technology]

In recent years, disc-type rotary tillers, in which a disc rotor with a plurality of tilling discs attached to a rotating shaft, is pivoted left and right at a gearing angle, have come into widespread use. The soil being tilled by the left and right disc rotors is turned over towards the center of the machine.
Processing to open the center part is important, and for this purpose, a conventionally known tilling claw is attached to a tilling shaft installed obliquely with respect to the direction of movement of the machine body, and this is rotated in the opening direction.

[Problem that the invention attempts to solve]

The above-mentioned tilling claws are driven into the soil diagonally with respect to the direction in which the machine moves, so thrust resistance is particularly large on the vertical blades, making the tilling claws susceptible to damage, which reduces the overall strength and durability of the tilling claws. There was a problem.

[Means to solve the problem]

The present invention was developed in consideration of the above-mentioned circumstances, and in order to solve the above problems, it consists of a mounting base, a vertical blade part, and a horizontal blade part, which are arranged obliquely in a horizontal plane with respect to the direction of movement of the aircraft. In the tilling claw attached to the tilling shaft provided in the tiller, the vertical blade part is bent from the boundary with the mounting base so as to be in substantially the same direction as the direction of movement of the machine body.

[Effect]

By having the structure as described above, the tilling claw of the present invention does not apply a large thrust resistance to the vertical blade part during tilling work, which reduces damage to the tilling claw and improves durability. .

【Example】

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In Fig. 1, reference numeral 1 denotes a tilling shaft that is rotatably supported at an angle θ on a horizontal plane with respect to the direction of movement of the machine, and a flange 2 is provided on this tilling shaft 1 so as to protrude perpendicularly to its axis. has been done. A tilling claw 3 is attached to the flange 2 with bolts and nuts 4. As shown in FIGS. 2 to 4, the tilling claw 3 consists of a mounting base 5, a vertical blade part 6, and a horizontal blade part 7, and has two mounting holes 5a provided in the mounting base 5.
It is attached to the flange 2 via the bolts and nuts 4. The vertical blade portion 6 is bent at an angle θ equal to the inclination angle θ of the tilling shaft 1 at the boundary with the mounting base 5 so as to be in substantially the same direction as the moving direction of the machine body. The horizontal blade portion 7 is curved to one side from the tip of the vertical blade portion 6. Since the present invention is constructed as described above, if the tilling shaft 1 is now rotated in the direction of the arrow in FIG. On the other hand, it is driven almost straight and passes through the soil while cutting, and the horizontal blade part 7 turns over the soil and releases it to perform tillage work. At this time, the vertical blade part 6 is driven into the soil in almost the same direction as the moving direction of the machine, so no thrust resistance is applied, and therefore the tilling claws 3 are not bent or broken. , durability can be increased. In particular, the present invention is suitable for working by rotating in the upcut direction for processing the central part of a two-way disc-type rotary tiller.
Furthermore, the tilling claw of the present invention can also be used in place of the disc of a disc rotor.

[Effect of the idea]

As explained above, according to the tilling claw of the present invention, the vertical blade portion is bent at an angle approximately equal to the inclination angle of the tilling shaft at the boundary with the mounting base, and rotated in approximately the same direction as the moving direction of the machine. As a result, thrust resistance is not applied to the vertical blade portion during tilling work, and the durability of the tilling claws can be increased. Further, it can be used in place of a disk in a disk-type rotary tiller.
