A kind of river sand screening equipment for construction site

Abstract

The invention discloses a river sand screening equipment for construction sites, which comprises a base, and support columns are symmetrically connected on both sides of the upper part of the base; a screening slot, and a screening slot is connected between the upper parts of the support columns; a guide rod, the upper part of the screening slot is symmetrical on one side A guide rod is connected; a hook, a hook is symmetrically hung on one side of the lower part of the screening groove; a collection barrel is connected with a collection barrel between the lower sides of the hook; a screening mechanism, a screening mechanism is arranged between the guide rod and the lower part of the screening groove; There is a rotating mechanism between the upper part of the base and the support column. The river sand screening equipment for construction sites disclosed in the present invention has the advantages of easily pushing out coarse sand and impurities for unified collection, automatically transferring river sand, automatically quantitatively cutting materials, and facilitating the movement of fine sand that has not slipped in the screening tank to the collection bucket, thereby reducing waste. advantage.

Description

technical field [0001] The invention relates to a screening device, in particular to a river sand screening device for construction sites. Background technique [0002] River sand, by definition, refers to the non-metallic ores produced by natural stone in the natural state, repeatedly collided and rubbed by the force of water for a long time, and the content of impurities occupies an important position in the field of construction. industry has made outstanding contributions. [0003] In order to obtain high-quality sand that can be used, it is generally necessary to screen out the river sand first. The traditional river sand screening technology mainly relies on manual screening by shaking the screen. However, this method is labor-intensive at first, unable to achieve batch screening, and secondly The coarse sand and impurities obtained by screening remain on the screen, which is inconvenient to collect. Repeated feeding also results in low screening efficiency. The conta...

[0003] In order to obtain high-quality sand that can be used, it is generally necessary to screen out the river sand first. The traditional river sand screening technology mainly relies on manual bumping screens for screening. However, this method is firstly labor-intensive and cannot achieve batch screening. The screened coarse sand and impurities remain on the screen, which is inconvenient to collect. Repeated feeding also leads to low screening efficiency. Finally, the container that catches the screened fine sand is likely to have residues and is difficult to clean, which will also cause waste
