A sand screening device for building construction

Abstract

A sand screening device for building construction comprises a bottom plate, a supporting device, a discharging device, a frame, a rotating device, a support device, a filtering device and a material collecting device. The bottom plate is provided with a first fixing block and a first material collecting box. The supporting device comprises a first supporting block, a pedal plate, a first supporting rod, a cross plate, first springs, a second supporting block and a first magnet. The discharging device comprises a discharging frame, a second spring, a first abutting block, a push block, a push rod, a vertical plate and third springs. The frame is provided with first through holes, a first cross rod and a fixing rod. The rotating device comprises a motor, a first support, a rotating shaft, a rotating frame, a centralizing ring, a second cross rod, fourth springs, a third cross rod, a first vertical rod and a fourth cross rod. The support device comprises a second support, a first inclined rod, a second vertical rod, a third support, a fifth cross rod, a fourth support, a sixth cross rod and a third filtering net. By means of the sand screening device, sand needing to be screened can be sufficiently screened, and the screening efficiency is high.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a sand screening device for construction. Background technique [0002] 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. [0003] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Contents of the invention [0004] The object of the present invention is to provide a sand screening device for building construction that can effectively solve the above technical problems. [0005] In order to solve th...
