Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and particularly to a rotary brush for a dust removal device based on aerodynamic force. Background Art

[0002] When the existing dust removal devices clean dust, most of them require brushes to clean the dust. When some machinery or furniture is processed and dust removal is carried out on some objects with complex surfaces, most of them need to be cleaned with brushes. The composition of these special brushes mostly uses a metal as the axis, with fixed pipes covered on the surface and an attachment body for fixing the brush filaments, which can effectively remove the dust adsorbed on the surface of the object.

[0003] The defects of the existing rotary brushes for dust removal devices are as follows:

[0004] 1. Patent document CN206083319U discloses an automatic dust removal brush, and the protected claim "comprises a base, a brush, a brush support and a driving device. The brush support includes a vertical adjusting rod for adjusting the brush up and down and a horizontal adjusting rod for adjusting the brush back and forth. The vertical adjusting rod and the horizontal adjusting rod are connected by a sliding flange. The vertical adjusting rod is fixedly connected to the base, the driving device is fixedly arranged at the front end of the horizontal adjusting rod, and the brush is fixedly connected to the output shaft of the driving device. Therefore, the present invention can not only automatically brush off the burrs and other garbage adhered to the surface of the workpiece to be processed by the brush, achieving a good dust removal effect, reducing the influence of the dust adhered to the workpiece on the product spraying qualification rate, saving production costs, improving the dust removal work efficiency, but also quickly and accurately adjust and correct the position between the brush and the workpiece, and the adjustment operation process is relatively simple and convenient". However, when this device cleans dust, there are still some dead corners that cannot be completely cleaned;

[0005] 2. After the existing rotary brushes for dust removal devices clean dust, the dust is easily adsorbed on the surface of the brush. After a long time, the dust removal effect of the brush will be reduced, and it is very inconvenient to clean the dust on the surface of the brush. Summary of the Invention

[0006] The purpose of the present invention is to provide a rotary brush for a dust removal device based on aerodynamic force, so as to solve the problems of inability to clean dead corners and inconvenient cleaning of the dust on the brush as mentioned in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A rotary brush for a dust removal device based on aerodynamic force, comprising a support shaft, a rotating roller and a cleaning ring, and a rotating roller is installed at one end of the support shaft;
