Dustproof crushing device for construction waste recycling

Abstract

The invention belongs to the technical field of construction, particularly relates to a dustproof crushing device for construction waste recycling, and aims to solve the problems that a conventional construction waste crushing device is relatively simple in structure, relatively simple in crushing mechanism design and general in crushing effect. The following scheme is provided: the dustproof crushing device comprises a shell, a feeding hopper is welded at the top end of the shell, the end, close to the top, of the shell is rotationally connected with a shaft column through a bearing, the outer wall of the shaft column is in key connection with a grinding roller, convex strips distributed at equal intervals are welded to the circumferential outer wall of the grinding roller, a counter-pressing mechanism is arranged on the side, close to the grinding roller, of the shell and comprises a sliding groove formed in one side of the shell, the inner wall of the sliding groove is slidably connected with an end arm, and a cubic rubbing block is welded to one side of the end arm. In the running process of a driving motor, the grinding roller can be driven to rotate under the transmission action of a worm and a worm gear, and waste is effectively extruded and ground in cooperation with the rubbing block.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a dust-proof crushing device for recycling construction waste. Background technique [0002] Construction waste refers to the muck, spoil, waste material, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, and pipe networks by construction units or individuals. According to the source classification, construction waste can be divided into engineering muck, decoration waste, demolition waste, engineering mud and so on. These materials are of no help to the building itself, but they are substances produced during the construction process and need to be dealt with accordingly, so as to achieve the ideal project construction. It is precisely because it is a whole process, so The consideration of its links is more important. With the acceleration of industrialization and urbanization, the construction industr...

AI Technical Summary

Problems solved by technology

[0003] During the recycling process of construction waste, in order to improve the utilization rate of the follow-up space and carry out the recycling operation, it needs to be crushed; the traditional construction waste crushing device generally has a relatively simple structure, and the design of its crushing mechanism is relatively simple. The crushing effect of garbage is not ideal. In addition, in the crushing process, it is easy to generate a lot of dust, which affects the working environment, so there are certain limitations.
