Background

Sand and stone are the most commonly used base materials in the building construction process, the quality of the sand and stone can influence the construction quality, and the existing sand and stone not only has river sand which is naturally mined, but also is made into machine-made sand by a sand making machine. Although natural sand and machine-made sand can be initially screened when leaving the factory, the production standard and the qualification rate of enterprises can not necessarily reach the construction standard, so that sand and stone particles on the market are possibly uneven, the construction quality is easily influenced by the uneven particles, and sand and stone screening can be carried out again through a sand screening machine when a building engineering company uses the sand and stone for guaranteeing the stability of the sand and stone.

The utility model discloses a but building construction concrete processing of hierarchical screening is with sand and stone sieving mechanism in 202122063910.2's patent, start motor drive first filter vat rotates, and first filter vat carries out preliminary screening to sand and stone, and the sand and stone after the filtration of first filter vat can drop on the second filter vat surface, and less sand and stone can get into in the second filter vat, and great sand and stone can drop on first filter screen and second filter screen through the third filter screen. However, the smaller sand and stones filtered by the first filter vat cannot be ensured to completely fall on the surface of the second filter vat and pass through the filter holes of the second filter vat, so that the smaller sand and stones are easily caused to directly fall on the first filter screen and the second filter screen, and the quality of classified screening is reduced.
