Multistage efficient sand screening device for constructional engineering

Abstract

The invention discloses a multi-stage high-efficiency sand screening device for construction engineering, which comprises a base plate, a sand screening box, a crushing device, a first screen, a second screen, a second spring, a sliding rod, a sliding sleeve, a connecting plate, a wool Brush, transmission mechanism, first gear, first reel, first traction rope, second gear, first cam, second cam, second reel and second traction rope, said transmission mechanism includes motor, The second disc, the movable rod, the first rack and the second rack, the present invention is provided with a crushing device, which crushes the agglomerated sand, avoids affecting the efficiency of sand screening, and is provided with a transmission mechanism, a first winding wheel, The second winding wheel, sliding rod, sliding sleeve, connecting plate and brush drive the brush to move left and right, brush the first screen and the second screen, and avoid the mesh holes of the first screen and the second screen from being blocked , Improve the screening efficiency, equipped with a first cam, a second cam and a second spring, so that the first screen and the second screen shake left and right, further improving the screening efficiency.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-stage high-efficiency sand screening device for construction engineering. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. Among them, "housing construction" refers to projects that have roofs, beams, walls, foundations, and can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, it is necessary to sieve the san...

AI Technical Summary

Problems solved by technology

[0004] The sand inside the sand pile is easy to agglomerate due to the high humidity or the presence of rainwater after rain. The current sand screening equipment generally does not have the crushing function, which reduces the sand screening efficiency, and the screen is easy to block during the screening process. The efficiency of sand screening is low, which increases the labor intensity of workers and reduces work efficiency, so there is an urgent need for a multi-stage high-efficiency sand screening equipment for construction projects.
