Concrete block crushing device for building construction

Abstract

The invention provides a concrete block crushing device for building construction. The concrete block crushing device for the building construction structurally comprises an outer frame, a front fenceseat, a base plate, a crushing motor, a crushing wheel outer disc, a concrete block crushing cavity and a concrete crushing adjusting and separating device; the outer frame is fixedly connected to the top end of the concrete block crushing cavity in an electric welding manner; and the crushing motor is fixedly mounted in the middle of the crushing wheel outer disc. According to the concrete blockcrushing device for the building construction, an overturning and separating mechanism is released through the shock sensation generated during crushing of a crusher, the overturning and separating mechanism is unfolded through the self weight of the overturning and separating mechanism, so that when concrete dust is lifted up, the concrete dust is blocked by an adjusting and separating mechanismduring the external impact process, meanwhile, the concrete dust is absorbed, guided and collected, the secondary usage is carried out through precipitation recovery, a large amount of the concrete dust is prevented from being scattered, then a safer state is kept from the air around the crusher, and concrete powder is collected while the good health of external operators is protected.

Description

technical field [0001] The invention belongs to the field of concrete, and more specifically relates to a device for crushing concrete block in building construction. Background technique [0002] Concrete blocks that are pushed and dismantled during construction can be re-crushed for secondary use of foundation and other filling layers. Due to the high hardness of concrete blocks, they will be discharged after being broken several times in the internal cycle, and the size of the crushed fragments is relatively uniform. , accompanied by more finely divided concrete dust. [0003] Based on the above description, the inventors found that the existing construction concrete block crushing device mainly has the following deficiencies, such as: [0004] During the crushing process of concrete blocks, more finely divided concrete dust will be produced. During the crushing process of the crusher, the return air will impact the inside of the crusher, and the concrete dust will be ra...
