Breaker of excavator and plate for sound proof and vibration prevention of breaker

摘要

Excavator breaker according to an embodiment of the present invention, for an excavator including a body, a tool installed in the lower end of the body, a bracket surrounding the body, and a soundproof vibrationproof plate installed between the body and the inner surface of the bracket. In the breaker, the soundproof dustproof plate, the base plate is installed in contact with the body, allowing the soundproof dustproof plate to slide on the contact surface of the body, and prevents the structural deformation of the soundproof dustproof plate; A first rubber layer formed on the base plate and absorbing vibration and noise transmitted from the body; And a second rubber layer formed around the surfaces of the first rubber layer except for the surface in contact with the base plate, embossed protrusions formed on the upper surface thereof, and the embossed protrusions contacting the inner surface of the bracket.;Breaker, Soundproof Dustproof Plate, Base Plate, Rubber Layer, Cord Paper
