A working method of fine sand screening equipment for construction site

Abstract

The invention relates to the field of building construction, in particular to a working method of fine sand screening equipment for a construction site. The fine sand screening equipment comprises a supporting seat, a separating containing device, a bearing screening device and a driving device. The separating containing device comprises a containing box, a sand inlet pipeline and a fine sand outlet pipeline. The driving device comprises a driven part, a positioning rotating part and a driving part. The driving part is in transmission connection with the driven part. The bearing screening device comprises a positioning screening plate arranged in the containing box, a rough sand outlet pipeline mounted on the positioning screening plate, a transmission connection part arranged at the top of the positioning screening plate, and a sand falling box arranged below the positioning screening plate. The bottom of the sand falling box is connected with the fine sand outlet pipeline, and the transmission connection part is in transmission connection with the positioning rotating part. By means of the working method, a whole positioning screening plate seat can be driven to swing, thus sandcan be screened, screening and separating operation for the sand is accelerated, output of manpower and material resources is reduced, and the screening efficiency is improved.

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...
