Problems solved by technology

However, the existing jaw crushers generally have the problem of strong vibration during the crushing process, which affects safe production; the reasons are mainly as follows: 1. Both the fixed jaw frame and the movable jaw group are rigidly fixed on the main body by lining plates First, it has no shock absorption effect, and it is easy to transmit the vibration to the frame when crushing stones; 2, the side plate of the frame body is rigidly connected to the frame base, and the shock absorption effect is not good
[0003] In addition, the two side plates of the frame body of the existing jaw crusher are connected and fixed by the frame tie rods. The frame rods will deflect due to the vibration of the frame, and then rotate axially and generate friction with the frame body side plates. At this time, The side panels of the frame body are very easy to wear and crack, which seriously affects its service life

Abstract

The invention relates to the field of mining equipment, and particularly relates to a novel jaw crusher. The novel jaw crusher comprises a rack and a moving jaw group arranged on the rack, wherein the rack comprises a main rack body, a fixed jaw rack arranged at the front end of the inside of the main rack body, and a toggle plate rack arranged at the back end of the inside of the main rack body, and the moving jaw group is arranged on the main rack body between the fixed jaw rack and the toggle plate rack; a crushing cavity is arranged between the moving jaw group and the fixed jaw rack. The novel jaw crusher has the advantages of good damping effect and long service life of rack.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a jaw crusher. Background technique [0002] Jaw crusher is a kind of mining machinery used for crushing stone. Its principle is to drive the movable jaw group to swing through the driving unit. The material is crushed. However, the existing jaw crushers generally have the problem of strong vibration during the crushing process, which affects safe production; the reasons are mainly as follows: 1. Both the fixed jaw frame and the movable jaw group are rigidly fixed on the main body by lining plates On the one hand, there is no shock absorption effect, and the vibration is easily transmitted to the frame when crushing stones; 2, the side plate of the frame body is rigidly connected to the frame base, and the shock absorption effect is not good. [0003] In addition, the two side plates of the frame body of the existing jaw crusher are connected and fixed by the frame tie rods. The...
