Safe and durable type jaw crushing device

Abstract

The invention discloses a safe and durable type jaw crushing device and mainly relates to the technical field of crushing machines. One end of a pull rod is connected with a hook position of the lowerpart of a moving jaw, and a spring sleeves the other end of the pull rod; the moving jaw is matched and connected with a toggle plate seat through a toggle plate; the toggle plate seat is in slidingconnection with an adjustment tapered iron; a force sensor is connected with the moving jaw and a display respectively; the surface of a rack is provided with a protective layer; and the protective layer is formed by an acid and alkali corrosion resistance layer, a high temperature resistance layer and a wear resistance layer. The safe and durable type jaw crushing device is very simple in whole structure, convenient and rapid to maintain and low in cost, enables an operator to conveniently monitor a running state of the safe and durable type jaw crushing device and is very good in safety andsealing effect and long in service life.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a safe and durable jaw crushing device. Background technique [0002] Jaw Crusher, also known as Tiger’s Mouth, consists of two jaw plates, the movable jaw and the static jaw. For the crushing of various ores and bulk materials in the chemical industry and other industries, the maximum compressive strength of the crushed materials is 320Mpa. [0003] The working part of the jaw crusher is two jaw plates, one is the fixed jaw plate, which is vertically fixed on the front wall of the machine body, and the other is the movable jaw plate, which is inclined in position and forms a crushing cavity with a large upper part and a smaller lower part with the fixed jaw plate. The movable jaw plate makes periodic reciprocating motions against the fixed jaw plate, sometimes separated and sometimes approached; when separated, the material enters the crushing cavity, and the finished product ...

AI Technical Summary

Problems solved by technology

[0005] 1. The overall safety is poor, and it cannot respond in time when an unexpected situation occurs, and cannot guarantee the efficient and stable operation of the crushing work for a long time;

[0006] 2. The service life is short, and the staff cannot monitor the specific working parameters of the crushing device in real time, so deviations and accidents are prone to occur during crushing work;

[0007] 3. The overall structure is very complex, and the load requirements are high, the maintenance is very cumbersome, and the manufacturing and operating costs are high
