Sand screening device used for building construction

Abstract

The invention relates to a sand screening device used for building construction. The sand screening device comprises a base plate, a support device, a discharging device, a frame body, a rotating device, a support frame device, a filtering device and a material collecting device, wherein a first fixing block and a first material collecting box are arranged on the base plate; the support device comprises a first support block, a pedal plate, a first support rod, a transverse plate, first springs, a second support block and a first magnet; the discharging device comprises a discharging frame, a second spring, a first jacking and propping block, a push block, a push rod, a vertical plate and third springs; a first through hole, a first transverse rod and a fixing rod are arranged on the frame body; the rotating device comprises a motor, a first support frame, a rotating shaft, a rotating frame, a concentrated ring, a second transverse rod, fourth springs, a third transverse rod, a first vertical rod and a fourth transverse rod; and the support frame device comprises a second support frame, a first oblique rod, a second vertical rod, a third support frame, a fifth transverse rod, a fourth support frame, a sixth transverse rod and a third filter net. The sand screening device used for building construction has the benefits as follows: sand needing to be screened can be fully screened, and the screening efficiency is high.

Description

[0001] This application is a divisional application of an invention patent application with application number: 2015107605141, invention name: a sand screening device for building construction, and application date: November 10, 2015. technical field [0002] The invention relates to the technical field of construction machinery, in particular to a sand screening device for construction. Background technique [0003] At present, the construction sand sold on the market contains a lot of impurities such as mud and soft stones, which must be screened before use. When the yellow sand is fished from the bottom of the river, it contains more water. If it hits the rainy season again, the old-fashioned The bracket sieve, the mesh of the sieve is easy to block, and only three or five shovels are sprinkled to sieve out a shovel of fine sand, and the quantity cannot meet the use demand. [0004] Therefore, it is necessary to provide a new technical solution to solve the above technica...

[0003] At present, the construction sand sold on the market contains a lot of impurities such as mud and soft stones, which must be screened before it can be used. When the yellow sand is fished out from the bottom of the river, it contains more water. If it hits the rainy season again, the old-fashioned Bracket sieve, the mesh of the sieve is easy to clog, sprinkle with three or five shovels to sieve out a shovel of fine sand, the quantity cannot meet the use demand
