Anti-accumulation sand and stone screening device for building construction

Abstract

The utility model relates to a sandstone screening device for building construction of anti -accumulation belongs to sandstone screening technical field. The sandstone screening device for building construction of anti -accumulation, include: mounting bracket, the top of mounting bracket is equipped with the vibration frame, through the interaction of fixed plate and multiple through -orifices, be favorable to make sandstone fall on the screen plate through multiple passages, carry out the preliminary dispersion to sandstone, and drive the push -plate drive multiple push rods to carry on the reciprocating movement through drive assembly, be favorable to make the push rod loose dispersion sandstone that accumulates in the local upper part of fixed plate, and utilize push -plate to push the sandstone that accumulates to the direction of adjacent through -orifices and fall on the screen plate from adjacent through -orifices, be favorable to make sandstone fall on the screen plate through multiple through -orifices dispersion, simultaneously push -plate will drive the reciprocating movement of moving rod and multiple shifter rods synchronously, be favorable to make multiple shifter rods fall on the sandstone on the screen plate again dispersion, thereby avoid the sandstone screening when accumulates on the screen plate, improved the screening efficiency of sandstone.
