Claims

[Claims for Utility Model Registration] (1) In a ripper device attached to the rear of a bulldozer that connects a shank and a ripper point with a pin, an enlarged diameter portion is provided approximately in the axial center of the pin hole of the shank. and forming a reduced diameter portion approximately in the axial center of the pin that engages with the pin hole, and connect the shank and the ripper point with a pin across the enlarged diameter portion of the shank and the reduced diameter portion of the pin. In this state, a ripper point mounting device characterized in that a partially cut-out elastic ring having an outer diameter larger than the pin hole diameter of the shank and an inner diameter smaller than the outer diameter of the pin is inserted. (2) The ripper point mounting device according to claim (1), characterized in that the pin hole and the enlarged diameter portion of the pin hole are formed into a bush instead of a shank. (3) In claim (1), the mounting of the ripper point is characterized in that when the shank and the ripper point are pin-coupled, the outer diameter of the elastic ring is pressed against the enlarged diameter portion of the pin hole. Device. (4) In claim (2), the mounting of the ripper point is characterized in that when the shank and the ripper point are pin-coupled, the outer diameter of the elastic link is pressed against the enlarged diameter portion of the pin hole. Device. (5) In claim (1), the pin hole is formed in the bush instead of the shank, the bush is divided into two in the axial direction, and an elastic ring is fitted into the inner end of the shank of the bush. Features: Ritsupa point mounting device.
