However, the tilling claw (nata claw) in the conventional rotary tilling device is used.
The surface of the nail had a smooth surface, and the soil with a lot of stickiness and water had a large friction resistance with the soil after entering the soil. Therefore, when cultivating such soil soil, the number of rotations of the rotary engine in the rotary cultivator may decrease, and if a clogging phenomenon occurs on the cultivating claw shaft, rotary cultivating work cannot be performed. It was in a state. However, when cultivating such soil soil, the rotary power of the rotary tiller must be increased. Therefore, an object of the present invention is to reduce the frictional resistance of the rotary tilling claws with the soil in the soil so that the rotary tilling work can be performed smoothly.

BEST MODE FOR CARRYING OUT THE INVENTION A rotary tillage claw of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a rotary tillage claw in the present invention, and FIG. 2 is a plan view of the same. As shown in FIG. 1 and FIG. 2, this rotary tillage claw (A) is extended from a mounting base (1) attached to a rotary shaft, and at least in the soil on the surface (front and back) of the claw. A large number of fine grooves (2) are formed in the entering range so as to be substantially in the same direction as the rotation direction. Further, the rotary tillage claws (A) are configured so as to form a pair with left and right symmetrical shapes.

The rotary tillage claw (A) thus constructed is attached to the rotary tiller of a tiller such as a tractor, and the rotary engine rotates to till the soil. And, in this rotary tillage nail (A), at least within the range of entering the soil on the nail surface,
As shown in FIG. 2, since a large number of fine grooves (2) are formed so as to be substantially in the same direction as the direction of rotation of the plowing claws, it is easy to get into the soil when plowing into the soil. However, the frictional resistance with the soil in the soil can be reduced. That is, by forming the groove (2), the contact area between the surface of the tilling nail (A) and the soil is reduced, and an air layer is formed between the surface of the tilling nail and the soil to prevent the two from adhering to each other. To do. Therefore, especially when cultivating clayy soil with a lot of water, in the conventional cultivating nail with a mirror-like nail surface, the soil adheres to the nail surface,
According to the rotary tilling claw (A) of the present invention, the soil does not adhere to the surface of the tilling claw, but the tilling work did not go as expected, and the tilling work can be performed smoothly even in such soil. Will be able to.

The groove (2) formed in the rotary tillage claw may be formed to be slightly rough as shown in the plan view of the rotary tillage claw (A ') in FIG. That is, the groove (2) formed in this rotary tiller is almost the same as the rotating direction of the tiller, and can reduce the frictional resistance between the surface of the tiller and the soil in the soil. If it exists, it may be formed in any manner and is not limited to the illustrated one. Further, the present invention can be carried out simply by forming a large number of grooves (2) on the surface of the rotary tillage claw, and therefore has an advantage that it can be easily carried out.
As described above, according to the present invention, by forming a large number of fine grooves on the surface (front and back) of the rotary tillage claw so as to be substantially in the same direction as the rotation direction of the tillage claw, It is possible to reduce the frictional resistance between them and prevent the inability to cultivate due to the reduction in the rotational speed of the rotary engine in the rotary tiller. Therefore, the rotary tilling work can be smoothly performed, and the work efficiency is significantly improved.
