Anti-blocking sand screening machine for constructional engineering prefabricated part and using method of anti-blocking sand screening machine

Abstract

The invention relates to the technical field of constructional engineering, in particular to an anti-blocking sand screening machine for constructional engineering prefabricated parts and a using method thereof.The anti-blocking sand screening machine comprises a feeding hopper, a drum screening machine body and a conveying belt, a stirring mechanism is arranged on the upper portion of the interior of the feeding hopper, and a pushing mechanism is arranged at a discharging opening of the feeding hopper; the feeding hopper is supported by a plurality of supporting legs; the drum screen machine body comprises a supporting frame, a first screening drum, a second screening drum and a drum driving mechanism, the first screening drum, the second screening drum and the drum driving mechanism are all arranged on the upper end face of the supporting frame, the second screening drum rotates in the first screening drum, and the drum driving mechanism is rotationally connected with the first screening drum; the conveying belt comprises a first conveying belt body and a second conveying belt body and is used for conveying sieved materials. When sand and sand blocks are screened and conveyed, a large amount of inrush sand or sand blocks can be scattered, and then the sand or sand blocks can be rapidly discharged to a screening position for good screening treatment.

Description

technical field [0001] The invention relates to a sand screening machine, in particular to an anti-blocking sand screening machine used for prefabricated components of construction engineering and a method for using the same, belonging to the technical field of construction engineering. Background technique [0002] Sand screening machine, also known as dry land sand screening ship, sand separator, is a sand separation equipment suitable for rivers, reservoirs, and coal yards; it is composed of a hull, a frame, a reducer, a conveyor belt, a rotary screen, an engine or a motor; this model Simple structure, economical and applicable, easy to operate; divided into drum type sand screening machine, washing drum type sand screening machine, vibrating screen type sand screening machine, etc.; Among them, the drum type sand screening machine is a kind of sand screening machine that is widely used in construction engineering. The drum sand screening machine imitates the working pri...

AI Technical Summary

Problems solved by technology

When the existing sand screening machine for prefabricated components of construction projects is used for sand screening, because the size of the feeding hopper gradually becomes smaller from top to bottom, when there is too much sand stored in the feeding hopper at one time, it is easy to cause the feeding The mouth of the bucket is blocked, and it needs to be dredged manually, which will affect the working efficiency of the sand screening machine, and the screening effect is not ideal.
