Fully-automatic intelligent sand screening machine used for construction site

Abstract

The invention relates to the technical field of construction machinery, in particular to a fully-automatic intelligent sand screening machine used for a construction site. The fully-automatic intelligent sand screening machine used for the construction site comprises a fixed frame, a sand screening mechanism, a sand conveying mechanism, a pulverizing mechanism, a regulating assembly and a conveying mechanism, and further comprises a sand storage box, a drive assembly, a second detecting element and a controller, wherein the sand screening mechanism comprises a sand screening frame which consists of two longitudinal boards and a transverse board; a steel wire rope is arranged between the sand screening frame and the fixed frame; an inclined sand screening net is arranged on the sand screening frame; one side of the sand screening frame is provided with a drive device; a regulating mechanism is arranged on the drive device; a first detecting element is arranged in the sand storage box; and the drive assembly is used for driving a sealing plate to operate while the first detecting element detects that sand particles are stored to predetermined height. The fully-automatic intelligent sand screening machine realizes automatic screening of sand, reduces labor intensity of a worker, effectively improves sand screening efficiency, can realize screening sands of different specifications, meets different construction needs, and has relatively high practicability.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a fully automatic intelligent sand screening machine for construction sites. Background technique [0002] Concrete is an indispensable part of modern houses, roads, and bridges. Concrete needs to be mixed with a certain proportion of cement, sand, coarse stones, and fine stones. This ratio will directly affect the quality of concrete; There will inevitably be sand or gravel with too large particles in the important raw materials, which will affect the ratio of the various components of the concrete, so the sand needs to be screened before production. [0003] The thickness of sand refers to the average thickness of sand particles of different particle sizes mixed together. Usually there are coarse sand, medium sand and fine sand. Grain gradation of sand refers to the matching ratio of sand size particles. Well-graded sand can not only save cement, but also impr...

AI Technical Summary

Problems solved by technology

However, the specifications of the sand screened by it are relatively single, which cannot meet the particle gradation of the sand, and has certain application limitations.
