Problems solved by technology

[0003] Yellow sand is one of the more commonly used materials in civil engineering construction. In order to meet the requirements for the use of yellow sand, many purchased yellow sands need to be screened in the later stage. At present, most construction sites still use manual sand screening. , the labor intensity of workers is high, the efficiency of sand screening is low, and the effect of sand screening is poor

Abstract

The invention discloses a small efficient sand screening machine for civil engineering. The machine comprises a box body; a sand screening net plate is matched at the bottom of the box body; multiplevibrators are arranged on the lower side of the sand screening net plate; a rotating shaft is arranged in middle of the upper side of the sand screening net plate; spiral blades matched with the bottom of the sand screening net plate are mounted on the rotating shaft; a driven belt wheel is fixedly mounted on the rotating shaft on the right side of the box body; the driven belt wheel is connectedwith a driving belt wheel mounted on an output shaft of a speed reducer through a triangular belt; an input shaft of the speed reducer is connected with an output shaft of a driving motor; and the speed reducer and the driving motor are fixed at the top of the box body. The machine can use one motor for controlling unloading and overturning of sand and prolonging the stop time of the sand, and canadjust the angle to improve the sand screening effect and efficiency and to reduce the production cost.

Description

technical field [0001] The invention relates to the field of civil engineering equipment, in particular to a small high-efficiency sand screener for civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, various engineering facilities built on the ground or underground, on land, directly or indirectly serving human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, Airports, offshore platforms, water supply and drainage, and protection projects, etc. Civil engineering refers to various technical work such as survey, planning, design, construction, inst...
