Environment-friendly building material recycling device

Abstract

The invention relates to the field of crushing, in particular to an environment-friendly building material recycling device which comprises an inner crushing body, an outer crushing body, a transmission rod, a sliding rod, an inner push rod and an outer push rod, and the sliding rod is driven by the transmission rod to push the inner push rod and the outer push rod which are arranged on the two sides of the transmission rod correspondingly so that the inner crushing body and the outer crushing body can rotate reversely; the inner crushing body and the outer crushing body slide and crush materials from two directions, and meanwhile, the sliding rod provides an external expansion component force for the inner crushing body and the outer crushing body, so that the inner crushing body expands from a nearly quadrangular octagon to a regular octagon while rotating, and then contracts inwards from the regular octagon to a nearly quadrangular shape, so that the materials are crushed by the inner crushing body and the outer crushing body. The outer crushing body is expanded into a regular octagon from an octagon which is slightly contracted inwards, then the regular octagon is contracted inwards into a shape close to a quadrangle, in the process, gaps of the crushing cavity are gradually reduced, materials with large particle sizes are extruded and crushed into qualified materials with small particle sizes in a sliding mode, and therefore the materials with the large particle sizes are crushed into the materials with the small particle sizes at a time.

Description

technical field [0001] The invention relates to the crushing field, in particular to an environment-friendly recycling device for building materials. Background technique [0002] In the construction process, if the used building materials are not handled properly, construction waste will be generated. Construction waste has a wide range of eroding effects on our living environment. , land quality and other environments have adverse effects. Environmental protection issues have increasingly become the focus of people's attention. In response to the national environmental protection call, people have developed environmentally friendly building materials that can be recycled and reused. Shredding can be recycled again. The existing environment-friendly building materials processing equipment usually puts the environment-friendly building materials with larger particle size into the equipment, and crushes the environment-friendly building materials step by step through a sing...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an environment-friendly recycling device for building materials to solve the problem that it is difficult to directly crush materials with large particle sizes into the target size at one time, and it is often necessary to replace the crushing equipment for multiple crushing.
