Compound pendulum jaw type crusher

Abstract

The invention relates to the field of mine equipment and particularly relates to a compound pendulum jaw type crusher. The compound pendulum jaw type crusher comprises a frame, as well as a driving unit and a moving jaw group which are arranged on the frame; the frame comprises a frame main body, as well as a fixed jaw frame arranged at the front end in the frame main body and a toggle plate frame arranged at the back end in the frame main body; the driving unit is in transmission and connection with the moving jaw group, the moving jaw group is mounted on the frame main body between the fixed jaw frame and the toggle plate frame, and a crushing cavity is formed between the moving jaw group and the fixed jaw frame; and the compound pendulum jaw type crusher has the advantages of convenience in disassembly and assembly, and stable pendulum of the moving jaw group.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a compound pendulum jaw crusher. Background technique [0002] Compound pendulum 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, and the movable jaw group and the fixed jaw frame are engaged with each other to simulate the movement of the two jaws of animals So as to crush the material. However, the existing compound pendulum jaw crusher has the following disadvantages: 1. The assembly process between the movable jaw shaft assembly and the supporting bearing seat in the movable jaw group is complicated and inconvenient to disassemble, which is embodied in the movable jaw shaft. The bearings and sealing rings in the assembly are all preheated and fitted on the eccentric shaft with interference. Not only the processing procedure is complicated but also the disassembly is inconvenie...

Problems solved by technology

However, the existing compound pendulum jaw crusher has the following disadvantages: 1. The assembly process between the movable jaw shaft assembly and the supporting bearing seat in the movable jaw group is complicated and inconvenient to disassemble. The bearings and sealing rings in the assembly are all preheated and fitted on the eccentric shaft with interference, which not only complicates the processing procedure but also makes it inconvenient to disassemble, which leads to troublesome daily maintenance of the movable jaw group; 2. The structure of the driving unit is single, all The motor pulley is set on the output shaft of the drive motor, and the motor pulley outputs to the movable jaw group through the conveyor belt; under this structure, the output shaft of the drive motor is subject to the tension force of the conveyor belt, and it is prone to deformation after long-term use, resulting in Incorrect, the conveyor belt transmission is unstable and the conveyor belt is prone to fall off
