Sand screening device for building construction

Abstract

The invention discloses a sand screening device for building construction. The sand screening device comprises a box body, a material collecting box, a material guiding hopper, a circular screen, an installation sleeve, a sponge ring, a screen cylinder, a cam, a feeding hopper, a stepping motor, a material inlet bin, a rotary sleeve, a telescopic rod, an installation plate, a driven gear, a gear ring, a guide rod, a brush, a movable bolt and an arc-shaped screen. According to the sand screening device, the sand can be better screened, the manual operation of the staff is avoided, thus the labor intensity of the staff is greatly reduced, the efficiency of sand screening is greatly improved, the sponge ring is impacted repeatedly by the screen cylinder which is horizontally moved, thus the sand is prevented from clogging the arc-shaped screen and the circular screen, meanwhile the brush is used for cleaning the arc-shaped screen, the screened fine sand is guided into the material collecting box through the material guiding hopper for collection, thus the sand is prevented from clogging screen holes on the arc-shaped screen and the circular screen, the screening efficiency is greatlyimproved, and meanwhile the practicability is also enhanced.

Description

technical field [0001] The invention relates to a sand screening device, in particular to a sand screening device for building construction, which belongs to the technical field of building construction. Background technique [0002] During the construction of the building construction site, sand is used, and the sand cannot be used directly when it is bought back. The sand needs to be sieved. The effect of sand treatment is not good, and it needs to go through several times of sand sieving treatment to meet the requirements, otherwise it will affect the engineering quality of construction. [0003] When existing sand is screened, it is mainly through the operator to use a shovel to throw the sand on the nearby screen. It is not easy to collect the sand after it is separated from the larger sand and gravel, which greatly increases the work intensity of the staff and consumes a lot of time. Therefore, a kind of building construction sand screening device is proposed for the...
