High-efficiency sand screening device for buildings

Abstract

The invention relates to a high-efficiency sand screening device for buildings. The high-efficiency sand screening device comprises a bottom plate, a frame device, an air cylinder device, a first filtering device, a second filtering device, a retaining ring device and a centrifugal device, wherein a recycling bin, a first locating rod, a first support rod, a sliding block and a first push-against rod are arranged on the bottom plate; the frame device comprises a first retainer ring, a feeding hopper, a second retainer ring, a first filter screen, a first vibrator, a second filter screen, a first support, a first connecting rod, a second support, a second connecting rod and a first inclined rod; the air cylinder device comprises a material distribution hopper, a first cross bar, a first vertical rod, a second cross bar, an air cylinder, a first pushing rod, a second pushing rod, a third cross bar, a second vertical rod and a fourth cross bar; and the first filtering device comprises a first support plate, a first through hole, a third retainer ring, a third filter screen, a second support rod, a third connecting rod, a third support and a fourth support. The high-efficiency sand screening device can rapidly and effectively screen sands and the blocking phenomenon can be avoided.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to an efficient sand screening device for construction. Background technique [0002] At present, the sand screened on the construction site is basically screened manually, that is, the screen is used to manually throw the coarse sand onto the screen to sort the sand and stones. This method of screening increases the labor force of the workers during screening Labor intensity, and the labor efficiency is very low, which increases the construction cost. [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 high-efficiency construction sand screening device that can effectively solve the above-mentioned technical problems. [0005] In order to solve the above technical problems, the present invention adopts the following tec...
