Damping device of crusher

Abstract

The invention relates to a damping device of a crusher. The damping device comprises damping moment arms and damping columns, wherein each damping column comprises a middle fixed column, springs, a tail fixed column and a handheld ring, the springs are arranged between the handheld ring and the middle fixed column as well as between the middle fixed column and the tail fixed column, through support holes are formed in the middle fixed column and the tail fixed column, and connecting bolts can be inserted into the support holes; one end of each damping moment arm is arranged on a crushing shaft in a sleeving manner, arc clamp plates are arranged on two sides of the other end of each damping moment arm, the tail ends of the arc clamp plates are connected through a flat plate, each damping moment arm, the corresponding arc clamp plates and the corresponding flat plate are connected to form a peripherally sealed jacket, and the corresponding damping column is located in the jacket and fixed with the arc clamp plates through the connecting bolt in the middle fixed column; the tail fixed columns are fixedly connected with support plates, arranged on a bearing box, through the connecting bolts. According to the damping device of the crusher, the damping effect is improved, and the service life of each crushing shaft can be prolonged; besides, the mounting is convenient and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of crushing machinery, in particular to a shock absorbing device for a crusher. Background technique [0002] The twin-shaft crusher is a twin-shaft shearing crusher that crushes materials into small-sized materials by shearing, squeezing, and tearing. The emergence of double-shaft crushers has made up for the limitation that crushers such as hammer crushers and jaw crushers can only crush brittle and hard materials such as coal, salt, gypsum, brick tiles, and limestone. , wood, film, plastic barrels, electronic waste, medical waste and other soft and tough materials can be well broken into small pieces for recycling. During the entire crushing process of the double-shaft crusher, the crusher will vibrate and cause impact on the frame. In order to protect the crusher shaft and the frame, a shock absorber needs to be installed between the two, and the existing shock absorber has a great impact on the crusher...

AI Technical Summary

Problems solved by technology

During the whole crushing process of the double-shaft crusher, the crusher will vibrate and impact the frame. In order to protect the shaft and the frame of the crusher, it is necessary to install a shock absorber between the two, and the existing shock absorber has a great impact on the crusher. The requirements are high, the structure of the shock absorption device is complex, the installation requirements are high, the installation is inconvenient, and the shock absorption effect is poor
