Small rotary type sand screening device

Abstract

The invention relates to a small rotary type sand screening device. The small rotary type sand screening device effectively solves the problems of inadequate sand screening and inconvenience of stonedumping. According to the technical scheme, the small rotary type sand screening device includes two vertical plates, wherein a screen which can move and rotate along the vertical plates left and right is arranged between the two vertical plates; the screen can be restored to the horizontal position, the mesh size of the screen can be adjusted, and baffles are arranged on the front and rear sidesof the screen; grooves are formed in the inner side faces of the vertical plates, and positioning rods corresponding to the grooves are arranged on the outer side faces of the baffles; a plurality ofguide rods are fixed to the screen, scraper blades which can slide along the guide rods left and right are arranged on the guide rods in a penetrating mode, pressure springs are connected between thescraper blades and the right ends of the guide rods, and fixing devices are arranged on the front and rear two baffles; and a movable plate is articulated on the left side of the screen, line wheels are arranged below the vertical plates, ropes are wound on the line wheels, the end portions of the ropes are connected with the screen, and eccentric wheels rotates alternately with the line wheels are arranged on the vertical plates. The small rotary type sand screening device improves the efficiency of sand screening and reduces the manpower.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a small rotary sand screening device. Background technique [0002] Some small sand screening devices are commonly used on construction sites. At present, drum type or reciprocating vibration type are mostly used. Most of the drum type sand screening devices cannot effectively separate sand and stones completely, and during the rotation of the drum, sand and stones are often separated. The stones fall together, so when the amount of sand is relatively large or the sand is relatively wet, it is easy for the sand to fall together with the stones before the sieve is cleaned. Because the stones are of different sizes, they are easy to get stuck in the screen. , after a period of time, it needs to be cleaned manually; at the same time, there are still some machines on the market that use horizontally placed gauze, and then use vibration to fully separate the sand from the stone...
