A shaking type sand screening device

Abstract

The invention discloses a shaking type sand and gravel screening device, which comprises a bottom plate, a motor, a housing and a screening barrel, wherein the housing is fixedly arranged on the bottom plate, a sleeve is arranged on the inner side of the housing in a rotating manner, the upper end of the sleeve penetrates through an upper cover plate of the housing and is fixedly connected with abevel gear D, bevel gears B are symmetrically arranged on the left and right sides of the bevel gear D, and are meshed with the bevel gear D, and the bevel gear B at the right end is fixedly connectedwith an output shaft of the motor; a tapered plate is fixedly arranged at the lower end of a rotating shaft, and through holes formed in middle of the tapered plate and a baffle plate are opposite toeach other; the screening barrel is also arranged in the housing, sliding chutes are symmetrically formed in the two ends of the screening barrel, sliding blocks are connected in the sliding chutes in a sliding manner, and the outer sides of the sliding blocks are hinged to pushing rods. The shaking type sand and gravel screening device is novel in design and easy to operate; the arranged screening barrel moves leftwards and rightwards and is also inclined to achieve an overturning effect on sand and gravel in the screening barrel to further improve the sand and gravel screening efficiency, is high in practicability and has high popularization value.

Description

technical field [0001] The invention relates to a screening device, in particular to a shaking type sand screening device. Background technique [0002] Sand and gravel are commonly used in building decoration, and sand and gravel refer to a loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074~2mm are called sand, and those with a particle size larger than 2mm are called gravel or breccia (the difference between the two lies in the degree of rounding, see the entry conglomerate and sandstone for details. ). If most of the gravel in the sand is gravel, it is called sand gravel. Some people also refer to sandstone as sandstone in daily life. [0003] Sand and gravel need to be screened before use. Sand and gravel with different particle sizes have inconsistent effects, so they need to be screened. Ordinary sand and gravel screening devices have a single screening method, which leads to low screening efficiency ...

Problems solved by technology

[0003] Sand and gravel need to be screened before use. Sand and gravel with different particle sizes have inconsistent effects, so they need to be screened. Ordinary sand and gravel screening devices have a single screening method, which leads to low screening efficiency and affects the progress of the project.
