Concrete slag crushing device

Abstract

The invention discloses a concrete slag crushing device. The device comprises a movable base; a screening motor is arranged at the top of the movable base, a rotating disc is connected to the right side of the screening motor, and a rotating column is fixedly connected to the bottom of the right side of the rotating disc; the right side of the rotating column is connected to a supporting block, the top of the supporting block is fixedly connected to a vertical rod, and a rotating seat is arranged at the top of the vertical rod; a cross rod is rotationally connected to the right side of the rotating seat, the right side of the cross rod is fixedly connected to a screening mechanism, and each of the left side and the right side of the bottom of the screening mechanism is provided with a swinging mechanism; and supporting columns are symmetrically and fixedly connected to the left side and the right side of the top of the movable base, a stabilizing seat is connected to the top of each ofthe two supporting columns in a sleeve mode, and supporting rods are fixedly connected to one sides, close to each other, of the two stabilizing seats. According to the concrete slag crushing device,the structural design is reasonable, the possibility that damage to the human body caused by manual use of a heavy hammer for crushing is reduced, recycling and reusing of the concrete slag are facilitated, the waste of resources is reduced, the labor intensity during manual screening can be reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a concrete slag crushing device. Background technique [0002] Concrete, referred to as "concrete" for short, refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, concrete has the characteristics of abundant raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but als...

Problems solved by technology

[0003] During the use of concrete in building construction, some concrete slag that forms slag blocks will be produced, which will be discarded directly, which will cause waste of resources. Because some concrete slag is relatively large in size, it cannot be recycled directly. When crushing manually with a heavy hammer , there will be the possibility of causing harm to the human body. At the same time, manual crushing and screening are labor-intensive and low-efficiency, which affects the progress of the work. Therefore, we propose a concrete slag crushing device
