Sand screening equipment with coarse screening and fine screening functions for civil engineering construction

Abstract

The invention relates to the technical field of civil engineering construction equipment, in particular to sand screening equipment with coarse screening and fine screening functions for civil engineering construction, and aims to solve the technical problem that existing sand screening equipment with coarse screening and fine screening functions for civil engineering construction is not ideal in effect. In order to solve the technical problem, the invention provides the sand screening equipment with the coarse screening and fine screening functions for civil engineering construction. The sand screening equipment with the coarse screening and fine screening functions for civil engineering construction is composed of a drying and smashing mechanism, a screening mechanism and a material returning mechanism, wherein feeding is carried out through a feeding hopper; then when sand falls, a draught fan and a heating wire are started and then are matched with structures such as a rotating bearing and an air jet hole, the falling sand can be dried; a crushing rod is driven to rotate through a first rotating shaft, so that sand blocks can be crushed, and the sand blocks are conveniently prevented from blocking a screen mesh and affecting the screening efficiency; and meanwhile, the sand is screened through vertical reciprocating vibration of a coarse screen mesh and a fine screen mesh, so that the screening quality is improved.

Description

technical field [0001] The invention relates to the field of civil engineering construction equipment, in particular to sand screening equipment for civil engineering construction which has both a coarse sieve and a fine sieve. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It refers to the materials, equipment and technical activities such as surveying, design, construction, maintenance and repair, as well as the object of engineering construction, that is, the construction in Various engineering facilities on the ground or underground, on land or in water, that directly or indirectly serve human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, and aircraft Fields, ocean platforms, water supply and drainage, and protective engineering, etc. The purpose of civil engineering...
