Problems solved by technology

[0003] For construction waste composed of concrete, sand, gravel, etc., it needs to be crushed and then further cleared and stacked. Metal objects are often mixed in these wastes. Large metal objects can be picked out by naked eyes, but metal objects Small parts are easy to be mixed, which will cause damage to the equipment during the crushing process; and the current crushing equipment is prone to generate a lot of dust when crushed, and the flying dust is easy to pollute the job site and the surrounding environment, which is not suitable for the crushing of construction waste.

Abstract

The invention discloses a screening and crushing device for construction waste. The device comprises a shell and a driving set, wherein the driving set and the shell are arranged in parallel, a crushing cavity is formed in the shell, the crushing cavity comprises a first impact tooth plate and a fourth impact tooth plate, wherein the first impact tooth plate and the fourth impact tooth plate are flat plates with tooth inside, and a second impact tooth plate, a third impact tooth plate and an impact sieve plate are sequentially arranged between the first impact tooth plate and the fourth impacttooth plate,; an adjustable impact plate is arranged below the impact sieve plate, and the adjustable impact plate and a spring rod are connected into a whole; and before material enters the crushingcavity from a feeding belt, small metal parts in the materials are attracted through soft magnetic strips on the feeding belt, and small metal parts are scraped down by a scraping plate in the operation process of the feeding belt and is collected by a sundries box, so that the damage to the mechanical in the crushing cavity during crushing and grinding is reduced.

Description

technical field [0001] The invention relates to construction machinery, in particular to a screening and crushing device for construction waste. Background technique [0002] 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 than 1 / 3 of the total urban waste. As of 2011, the stock of urban solid waste in China has reached 7 billion tons, and the total amount of construction waste can be estimated at 2.1 billion to 2.8 billion tons, with more than 300 million tons of new construction waste generated every year. [0003] For construction waste composed of concrete, sand, gravel, etc., it needs to be crushed and then further cleared and stacked. Metal objects are often mixed in these wastes. Large metal objects can be picked out by naked eyes, but metal objects Small parts are easy to be mixed, ...
