Efficient sand screening device for construction engineering

Abstract

The invention discloses an efficient sand screening device for construction engineering. The efficient sand screening device comprises a box, a feeding hopper, a first screen plate, a second screen plate, a connecting plate, a connecting block, an electric pushing rod, a sliding sleeve, a spring, a first connecting rod, a ratchet wheel, a first motor, a guiding sleeve, a U-shaped rod, a pushing plate, a hairbrush, a second motor, a second connecting rod, a vertical rod, a conical plate, a movable plate, a rotating shaft and collecting frames. According to the efficient sand screening device for construction engineering, the first screen plate, the second screen plate and the electric pushing rod are arranged, therefore, the size of screen holes can be adjusted, and then sand with different particle sizes can be screened out to meet the different construction operation requirements; the first motor, the ratchet wheel and the first connecting rod are arranged, the first screen plate and the second screen plate can be driven to move left and right through cooperation of the first motor, the ratchet wheel and the first connecting rod, and therefore the sand screening efficiency is improved; the U-shaped rod, the pushing plate, the hairbrush, the second connecting rod, the vertical rod and the second motor are arranged, therefore, sand can be spread on the first screen plate, the hairbrush continuously brushes the second screen plate to avoid the condition that circular holes of the second screen plate are blocked, and then the screening efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a high-efficiency sand screening device for construction engineering. Background technique [0002] Construction engineering refers to the planning, survey, design and construction, completion and other technical work and the completed engineering entity and the installation project of the supporting lines, pipelines and equipment for new construction, reconstruction or expansion of houses, buildings and auxiliary structures and facilities. . It also refers to the construction of various houses and buildings, also known as construction workload. This part of the investment must be built and used, and can only be realized through construction 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 f...

AI Technical Summary

Problems solved by technology

[0004] The current sand screening equipment is generally only equipped with a first-level sand screening device, which can only screen out sand of one particle size, which cannot meet different work needs. In addition, the screen mesh is easy to block during the screening process, and the sand screening efficiency is low, which increases the number of workers. The labor intensity reduces the work efficiency, so there is an urgent need for a multi-stage high-efficiency sand screening equipment for construction
