Concrete crushing device and crushing method thereof

Abstract

The invention discloses a concrete crushing device and a crushing method thereof. The concrete crushing device comprises a bottom plate, a crushing mechanism is arranged on one side of the upper end of the bottom plate, the crushing mechanism comprises an L-shaped mounting frame and a crushing base, the lower end of the L-shaped mounting frame is fixedly connected to the bottom plate, a hydraulic cylinder is arranged at the upper end of the L-shaped mounting frame, the output end of the hydraulic cylinder penetrates through the L-shaped mounting frame, a connecting shaft is arranged at the tail end of the hydraulic cylinder, and a cover plate is arranged on the connecting shaft in a sliding sleeving mode. According to the concrete crushing device and the crushing method thereof, through the combined action of a U-shaped protection plate and a baffle, small blocks of concrete burst out can be intercepted to prevent the small blocks of concrete from impacting a human body, so that the safety of the crushing device is effectively improved; under driving of a motor, in cooperation with use of a half-face gear and a rack, circulating reciprocating movement of a cleaning scraper is achieved, so that cleanliness in a T-shaped crushing groove is ensured; and therefore, subsequent concrete block crushing operation is facilitated.

Description

[0001] This application is a divisional application, the original patent number is: 202011076301.4, the application date is October 10, 2020, and the title of the invention is: a concrete crushing device with a protection mechanism and its crushing method. technical field [0002] The invention relates to the technical field of building construction, in particular to a concrete crushing device and a crushing method thereof. Background technique [0003] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. , Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete, and the concrete waste in the constructi...

AI Technical Summary

Problems solved by technology

[0004] However, most of the existing concrete crushing devices are operated in the open air. Due to the lack of protection mechanism, the small pieces of concrete ejected from the crushing device are easy to hit the human body, thus causing injury to the staff and reducing the safety of the crushing device. In addition, the existing crushing device is not equipped with a cleaning mechanism, and only adopts the method of tilting the crushing base for unloading, resulting in a large amount of concrete remaining on the tilting base, which is not convenient for subsequent concrete block crushing operations. Therefore, we A concrete crushing device and its crushing method are proposed to solve the above problems
