Construction engineering construction waste crushing device

Abstract

The invention discloses a construction engineering construction waste crushing device. The device comprises a bottom plate and a box body, wherein a fixed shell is mounted at the upper part of the rear end of the box body, crushing rollers are symmetrically arranged bilaterally in the upper part in the box body, transmission rods are symmetrically mounted at the front ends and the rear ends of thecrushing rollers, the front transmission rod penetrates through the box body to be rotatably connected to the inner wall of the fixed shell, a motor is mounted at the front end of the fixed shell, the rear end of the motor penetrates through the fixed shell to be fixedly connected with the left side transmission rod, the outer surfaces of the transmission rods are sleeved with full gears, the full gears are positioned in the fixed shell, a first belt pulley is arranged on the outer surface of the left side transmission rod in a sleeve mode, and is positioned in the fixed shell, a half gear sleeves the outer surface of the right side transmission rod, a rack is vertically arranged in the fixed shell, the rack meshes with the half gear, a fixing block is mounted at the lower end of the rack, a telescopic device is arranged at the lower end of the fixing block, and a first spring sleeves the outer surface of the telescopic device. According to the device, metal waste with value in use inconstruction waste can be recycled through magnets.

Description

technical field [0001] The invention relates to a crushing device, in particular to a construction waste crushing device for construction engineering. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated in the production activities of people engaged in demolition, construction, decoration, repair and other construction industries. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] In construction projects, crushing devices will be used to crush large pieces of construction waste. After the existing crushing device is crushed, large pieces of construction waste will remain. It ...

Problems solved by technology

[0003] In construction projects, crushing devices will be used to crush large pieces of construction waste. After the existing crushing device is crushed, large pieces of construction waste will remain. It is necessary to find large pieces of construction waste in the crushed garbage pile and then crush them. It is very troublesome. At the same time, the crushing device will also crush the valuable metal waste in the construction waste, which cannot effectively recycle the metal waste.
