Abstract

The invention relates to the field of civil engineering machinery, in particular to a high-efficiency sand screening device for civil engineering construction. The high-efficiency sand screening device comprises a sand screening machine body, wherein a plurality of groups of sand conveying assemblies are mounted on the inner side of the sand screening machine body from top to bottom; a sand receiving groove is obliquely formed in the inner side of each group of sand conveying assemblies; the other ends of the sand receiving grooves are correspondingly provided with sand outlets in the side wall of the sand screening machine body; a plurality of vent holes are formed in the side wall of the sand screening machine body and located in the upper side of the end, close to the sand conveying assembly, of each sand receiving groove; branch air pipes communicated with the vent holes are correspondingly mounted on the outer side of the sand screening machine body; all the branch air pipes are connected with a main air pipe; an air blower connected with the main air pipe is further mounted on the outer side wall of the sand screening machine body; and a sand storage box used for containing sand discharged from the sand outlets and discharging redundant air in the sand screening machine body is further mounted on the outer side of the sand screening machine body. The high-efficiency sand screening device can conduct multi-layer sand screening operation, has the functions of airflow-assisted sand screening and sand discharging, and improves the sand screening efficiency and effect.

Description

technical field [0001] The invention relates to the field of civil machinery, in particular to a high-efficiency sand screening device for civil construction. Background technique [0002] Civil engineering refers to various technical work such as survey, planning, design, construction, installation and maintenance for new construction, reconstruction or expansion of buildings, structures and related supporting facilities, etc. engineering entities. [0003] The existing sand screening devices for civil construction have the following disadvantages: 1) The sand screening structure is single, and only one-time sand screening can be performed in a single layer, and the sand screening effect is poor and the efficiency is low; 2) There is no air-assisted sand screening and The sand discharge function affects the efficiency and effect of sand screening. [0004] Therefore, in view of the above present situation, there is an urgent need to develop a high-efficiency civil constru...
