Abstract
The present invention provides a breaker mounting bracket a breaker mounting bracket for mounting a breaker body on a distal end of an arm of a working machine or the like. The breaker mounting bracket includes left and right side plates which are arranged to face each other in an opposed manner, an end plate which is provided between proximal end portions of both side plates and forms a connecting portion with a distal end of the arm of the working machine, and resilient bodies which come into contact with and support the breaker body and are mounted on inner sides of the left and right side plates and the end plate.
Claims6
A breaker mounting bracket a breaker mounting bracket for mounting a breaker body on a distal end of an arm of a working machine or the like, the breaker mounting bracket comprising:
- left and right side plates which are arranged to face each other in an opposed manner;
- an end plate which is provided between proximal end portions of both side plates and forms a connecting portion with a distal end of the arm of the working machine;
- and
- resilient bodies which come into contact with and support the breaker body and are mounted on inner sides of the left and right side plates and the end plate.
A breaker mounting bracket for mounting a breaker body which mounts a chisel on a distal end thereof on a distal end of an arm of a working machine, the breaker mounting bracket comprising:
- a pair of left and right side plates which are mounted on both side surfaces of a breaker body which is formed in a longitudinally elongated rectangular parallelepiped shape;
- an approximately square end plate which is mounted on proximal ends of the side plates and is mounted on a connecting portion which is connected with the distal end of the arm of the working machine;
- an end-plate side resilient body which is arranged on an inner side of the end plate and is brought into contact with a proximal end portion of the breaker body;
- first side-plate side resilient bodies which are respectively formed on inner sides of the left and right side plates and support the chisel in the vibration direction cooperatively with the end-plate side resilient body;
- second side-plate side resilient bodies which are contiguously formed with the first side-plate side resilient bodies and impart a pushing force in the direction orthogonal to the vibration direction;
- a longitudinal resilient body which brings a proximal end surface of the breaker body into contact with a distal end surface;
- and
- third side-plate side resilient bodies which reinforce a supporting force of the breaker body in the direction orthogonal to the vibrating direction.
