Crusher with multi-stage crushing function

Abstract

The invention discloses a crusher with a multi-stage crushing function. The crusher comprises a storage box, a conveying rod, a conduction channel, a feeding box, a box body and a bottom plate; the box body is fixed to the bottom plate; a rotating motor is arranged in the center of the outer side wall of the top of the box body; the output end of the rotating motor is connected with a rotating shaft; the rotating shaft vertically extends into an inner cavity of the box body; a plurality of groups of crushing rods are uniformly arranged on the rotating shaft; first crushing rollers are arranged in the box body; first guide plates which are inclined downwards are arranged below the first crushing rollers; a vertical rotary grinding disc and a telescopic grinding disc are arranged below the first material guide plates; two second material guide plates are arranged below the rotary grinding disc and the telescopic grinding disc; a static crushing plate and a swing crushing plate are arranged on the two sides of the upper portion of s discharging port respectively; and air suction fans are arranged at the upper end and the lower end of the box body respectively. According to the crusher with the multi-stage crushing function, dust generated in the crushing process can be collected, and the situation that the dust flies to harm the health of constructors and pollute the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to a crusher with multi-stage crushing functions. Background technique [0002] Crusher is a commonly used processing machine, but the structure of the previous material crusher is relatively simple. The material is only crushed once in the inner cavity and then discharged in a hurry, resulting in very uneven and irregular particle sizes. The entire material processing The effect is very poor and the subsequent process is greatly restricted and affected. In view of the above defects, it is necessary to design a crusher with multi-stage crushing function. Contents of the invention [0003] The object of the present invention is to provide a crusher with multi-stage crushing function, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a cr...
