を特徴とする。 In summary, the rotary tillage device with an inclined claw shaft for processing residual tillage according to the present invention has the following features:
On the outer peripheral surface of the tilted claw shaft and on a plane that includes the intersection of the tilling claw shaft and the tilted claw shaft and is perpendicular to the tilted claw shaft, separate from the tilted claw shaft. It is characterized in that the annular protrusion of the body is fixed, and a bowl-shaped protective cover is fixedly connected to the tilling claw shaft, the inner circumferential surface of which is close to or in sliding contact with the annular protrusion.

利にして、確実に行なえるに至つた。 That is, by covering the annular protrusion 7 provided on the inclined claw shaft 3 side with the bowl-shaped protective cover 8 fixed to the tilling claw shaft 2 side, it is possible to not only prevent mud etc. from entering the seal portion, but also By preventing straw, grass, etc. from wrapping around the inclined claw shaft 3 and from moving the wrapped objects toward the sealing portion along the outer peripheral surface of the inclined claw shaft 3, the life of the sealing portion can be increased. In particular, according to the present invention, the annular protrusion 7 is not formed integrally with the inclined claw shaft 3 by machining or the like, but is formed separately from the inclined claw shaft 3. By fixing to the inclined claw shaft 3, the manufacturing process of the inclined claw shaft 3 and the annular protrusion 7 can be facilitated.Moreover, if the annular protrusion 7 becomes deformed or worn, only this annular protrusion 7 can be replaced. Overall, it has become possible to prevent damage to the sealing part due to straw, grass, etc. wrapping around the seal and mud entering the seal, making it extremely economical and reliable.

たつて良好に使用することができる利点がある。 Moreover, the annular protrusion 7 is arranged on a plane that includes the intersection of the tilling claw axis X and the inclined claw axis X 1 and is perpendicular to the inclined claw axis X 1 with respect to the inclined claw axis 3 . For example, since it is necessary to absorb the eccentricity of the inclined claw shaft 3 that rotates eccentrically with respect to the tilling claw shaft 2, as in the case where it is provided at a position shifted from the intersection point P, the annular protrusion 7 The design of the seal damage prevention member eliminates the inconvenience of having to be formed from a rubber member that can expand and contract in the radial direction, and can also be formed from a hard member such as plastic. It has a large degree of freedom, and even when it is made of a rubber member, there is little wear due to relative rotation between the tilling claw shaft 2 and the tilting claw shaft 3, and the seal damage prevention member can be used for a long time. It has the advantage that it can be used for
