A construction site sand screening device for preventing dust

Abstract

The invention discloses a construction site sand screening device capable of preventing raise dust. The construction site sand screening device capable of preventing raise dust comprises a base, a sand screening frame, a screen plate, a rotating disc, a cylinder body and a water storing groove, an annular cavity is formed in the middle inner cavity wall, the edge of the screen plate extends into the cavity and is connected with a cavity top of the cavity through a spring, and an annular plate is fixed to the bottom of the screen plate and is provided with a sliding groove; and the rotating disc is connected to the lower portion of the annular plate in a matched manner, the cylinder body is fixed to the left side of the bottom of the sand screening frame, and the water storing groove is fixed to the left side of the top of the base. The construction site sand screening device is compact in structure and convenient and quick to operate, the sand screening efficiency can be effectively improved, the sand screening effect is guaranteed, the dust removal function is achieved, the dust generated in the sand screening process is prevented from polluting the environment, and the body health of a constructor is protected; and meanwhile, through linkage design, sand screening and dust removal can be carried out at the same time, the timeliness of dust removal is guaranteed, and the overall device is operated and controlled more easily.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction site sand screening device for preventing dust. Background technique [0002] The construction industry is a production sector specializing in civil engineering, house construction and equipment installation, as well as engineering survey and design. Its products are buildings, structures and facilities of various factories, mines, railways, bridges, ports, roads, pipelines, residences and public facilities. Sand screening device is a common equipment in the construction industry. [0003] A large amount of dust will be generated during the sand screening process, and most of the existing sand screening devices have no dust removal function, which will pollute the environment and affect the health of construction workers. Contents of the invention [0004] The object of the present invention is to provide a construction site sand screening device for preven...
