Material crushing device for subway construction

Abstract

The invention provides a material crushing device for subway construction. The material crushing device for subway construction comprises a box body; two material feeding pipes are symmetrically and fixedly connected to the top surface of the box body; a material feeding funnel fixedly communicates with the top ends of the two material feeding pipes; a transverse plate is fixedly connected to theinterior of the box body; a vertical pipe is embedded into the center of the cross plate; the bottom surface of a sealing ring fits a bucket body; multiple outriggers are symmetrically and fixedly connected to the bottom surface of the box body; a rotating disc fixedly sleeves the vertical pipe; multiple vertical rods are fixedly connected to the bottom surface of the rotating disc in an annular shape; the side wall of a convex block fits the side wall of the vertical rod; the vertical pipe is rotationally connected with the transverse plate; the vertical pipe is rotationally connected with the bucket body; the transverse plate is made of an alloy steel material; the connecting mode between the box body and the bucket body is welding; and the model of a three-phase asynchronous motor is Y132M-4. The material crushing device for subway construction has the advantages that functional diversity and high practicability are realized; materials can be sufficiently dried to be convenient forthe following crushing; the materials can be sufficiently crushed; materials can be discontinuously fed; blockage of a machine can be effectively prevented; the working efficiency can be enhanced; andindustrial demand can be met.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a material crushing device for subway construction. Background technique [0002] Civil engineering refers to the materials and equipment used and technical activities such as surveying, design, construction, maintenance, repair, etc., that is, construction on the ground or underground, on land or in water, directly or indirectly for human life, production, military, Various engineering facilities for scientific research services, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, ocean platforms, water supply and drainage, and protection projects, etc., the traditional subway crushing device has poor crushing effect , can not meet the needs of industry, and it is easy to cause machine blockage and reduce work efficiency when broken. Contents of the invention [0003] According to the technical problems raised...
