Two-stage linkage vibrating screen device for building screening

Abstract

The invention discloses a two-stage linkage vibrating screen device for building screening, which includes a frame, a two-stage drive mechanism, a screening cylinder and a crushing cylinder. A beam frame is welded on the top of the frame, and an adding bucket is welded on the beam frame. The outside of the crushing cylinder is welded to the frame through bearing sleeves; a ring gear is welded on the outer wall of the crushing cylinder, and the side of the ring gear is meshed with the driving gear, and the driving gear is welded on the rotating shaft of the motor C, which is installed on the machine on the frame; crushing teeth are welded on the inner wall of the crushing cylinder, and a crushing hammer is installed inside the crushing teeth; the crushing hammer and the crushing teeth crush the building materials, and the grinding disc further grinds and pulverizes the crushed materials. Driven by the two-stage drive mechanism Next, the first-stage screen and the second-stage screen are linked to carry out double-stage vibration screening of building materials, which improves the efficiency and efficiency of building material screening, reduces the installation cost of screening drives, and improves the quality of building material screening.

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
