Two-stage linkage vibrating screen device for building screening

Abstract

The invention discloses a two-stage linkage vibrating screen device for building screening. The two-stage linkage vibrating screen device for building screening comprises a rack, a two-stage driving mechanism, a screening barrel body and a crushing barrel; a cross beam frame is welded to the top end of the rack; an adding hopper is welded to the cross beam frame; the exterior of the crushing barrel is welded to the rack through a bearing sleeve; a gear ring is welded to the outer wall of the crushing barrel; the side face of the gear ring is connected with a driving gear in an engagement manner; the driving gear is welded to a rotating shaft of a motor C which is installed on the rack; crushing teeth are welded to the inner wall of the crushing barrel; a crushing hammer is installed on the inner sides of the crushing teeth; the crushing hammer and the crushing teeth crush building materials; a grinding disk further grinds and smashes the crushed materials; under the driving of the two-stage driving mechanism, a first-stage screen net and a second-stage screen net are in linkage to perform two-stage vibration screening on the building materials, the building material screening efficiency is improved, the installing cost of a screening driver is reduced, and the building material screening quality is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a double-stage linkage vibrating screen device for construction screening. Background technique [0002] In the process of building construction, a large amount of building materials such as sand and gravel need to be used. Before the use of sand and gravel and other materials, they need to be screened to filter out the large particle materials and ensure the uniformity of the materials used. The current screening method is manual screening, which is time-consuming and laborious, and the screening efficiency is low. Usually, a single-layer screen is used for screening, and the screening quality is poor, and secondary treatment is often required. After being pushed for a long time, the sand is easy to be damped and agglomerated, and cannot be crushed and ground to disperse during screening, and cannot pass through the screen, which not only reduces the screening eff...

Problems solved by technology

The current screening method is manual screening, which is time-consuming and laborious, and the screening efficiency is low. Usually, a single-layer screen is used for screening. The screening quality is poor, and secondary treatment is often required.

After being pushed for a long time, the sand is easy to be damped and formed into lumps. It cannot be crushed and ground to disperse during screening, and cannot pass through the screen, which not only reduces the screening efficiency, but also causes waste of some sand raw materials.

Mechanical construction material screening equipment, the drive structure for the screen is complex and does not need to be driven by an independent drive mechanism to drive the screening movement, the screening cost is high, and the equipment is expensive
