A concrete crushing device with a protection mechanism and its crushing method

Abstract

The invention discloses a concrete crushing device with a protection mechanism and a crushing method thereof. It includes a bottom plate, and a crushing mechanism is provided on the upper side of the bottom plate. The crushing mechanism includes an L-shaped mounting frame and a crushing base. The L The lower end of the L-shaped mounting frame is fixedly connected to the base plate, and the upper end of the L-shaped mounting frame is provided with a hydraulic cylinder. The output end of the hydraulic cylinder runs through the L-shaped mounting frame and is provided with a connecting shaft at its end. The sliding sleeve is provided with a cover plate; through the joint action of the U-shaped protective plate and the baffle plate, the present invention can intercept the small pieces of concrete that are ejected to prevent the small pieces of concrete from hitting the human body, thus effectively improving the safety of the crushing device. The invention realizes the circular reciprocating movement of the cleaning scraper under the drive of the motor, combined with the use of the half-face gear and the rack, thereby ensuring the cleanliness of the T-shaped crushing tank and facilitating subsequent crushing of concrete blocks. conduct.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete crushing device with a protection mechanism and a crushing method thereof. Background technique [0002] 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 construction process can be crushed processing for recycling. [0003] 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...

AI Technical Summary

Problems solved by technology

[0003] 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, which will cause injury to the staff and reduce 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 with a protection mechanism and its crushing method are proposed to solve the above problems
