A construction site fine sand screening equipment

Abstract

The invention relates to the field of building construction, in particular to fine sand screening equipment for a construction site. The fine sand screening equipment comprises a supporting base, a separation and accommodating device, a load-bearing screening device and a driving device. The separation and accommodating device comprises an accommodating box, a sand inlet pipe and a fine sand discharge pipe. The driving device comprises a driven part, a positioning rotating part and a driving part, wherein the driving part is connected with the driven part in a transmission mode. The load-bearing and screening device comprises a positioning screening plate disposed in the accommodating box, coarse sand discharge pipes installed on the positioning screening plate, transmission connecting parts disposed at the top of the positioning screening plate and a sand falling box disposed under the positioning screening plate. The fine sand discharge pipe is connected with the bottom of the sand falling box, and the transmission connecting parts are connected with the positioning rotating part in a transmission mode. The fine sand screening equipment for the construction site can drive a wholepositioning screening plate seat to make swinging movement, thereby realizing the screening operation of sand and gravel, improving the screening and separation operation of the sand and gravel, reducing the output of manpower and material resources, and improving the screening efficiency.

Description

technical field [0001] The invention relates to the field of building construction, in particular to fine sand screening equipment for construction sites. Background technique [0002] When construction is carried out on the construction site, sand and gravel are one of the main raw materials for construction. At present, when construction workers need to screen sand and gravel, the existing screening device is vibration screening. Sand and gravel will be concentrated and aggregated, and the requirements for sand and gravel during construction are relatively strict. They are usually divided into fine sand and large sand, so workers will screen through the sieving device during processing. [0003] The traditional screening method is mainly manual screening, which consumes time and manpower, greatly reduces the production efficiency and screening quality, and reduces the screening efficiency of the screening device. Contents of the invention [0004] The purpose of the pre...
