Crusher for construction waste

Abstract

The invention belongs to the technical field of construction waste treatment, and particularly relates to a crusher for construction waste. The crusher comprises a machine shell, wherein a crushing cavity is formed in the machine shell, and a crushing wheel is rotationally connected in the crushing cavity; a supporting rod is arranged at the bottom of the machine shell, a discharging hole is formed in the bottom of the crushing cavity, an inclined screen is arranged below the discharging hole, and the screen is fixedly connected with the supporting rod through a support; the lower portion of the screen is provided with a first hopper for collecting concrete particles, a feeding hopper is hinged to the upper portion of the machine shell, the height of the crusher is reduced after the feeding hopper is turned over, the transportation is convenient, the feeding hopper is large at the upper portion and is small at the lower portion, and the side wall on one side of the feeding hopper is vertically arranged and is tangent to the crushing cavity. According to the crusher, the side wall at one side of the feeding hopper is vertically arranged and is tangent to the crushing cavity, so thatwood garbage with the larger length is tightly attached to the side wall tangent to the feeding hopper and the crushing cavity when the wood garbage is crushed, the beating of wood materials is reduced, meanwhile, the condition that the wood materials are clamped into the feeding hopper is reduced, and therefore, the crushing efficiency of the wood materials is increased.

Description

technical field [0001] The invention belongs to the technical field of construction waste treatment, in particular to a crusher for construction waste. Background technique [0002] Construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste generated during the construction, laying or demolition, and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. [0003] Construction waste is classified according to the source of generation. Construction waste can be divided into engineering dregs, decoration waste, demolition waste, and engineering mud. block, waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0004] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing. The amount of construction waste in China has accounted for more t...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, most of the construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is piled in the open air or landfilled, which consumes a lot of construction funds such as land acquisition fees, garbage removal and transportation fees, and at the same time , problems such as dust, dust and sand flying in the process of cleaning and stacking have caused serious environmental pollution. After the wooden waste is piled up at the construction site, it is difficult to clean and transport quickly because of the different lengths. The wooden waste is often mixed with cement blocks. and iron nails and other impurities, it is difficult to recycle the problem, a kind of crusher for construction waste proposed by the present invention
