The two ends of the self-cleaning brush roller 9 are respectively fixedly sealed and connected to the third transmission gear 6. The self-cleaning brush roller 9 includes a bristle fixing cylinder 22 and a plurality of rows of bristles 22 arranged along the circumferential direction of the bristle fixing cylinder 22. There is a self-cleaning gap between two adjacent rows of bristles 22. A plurality of second water outlet holes 21 are arranged on the shell of the brush roller 9, the hard cleaning scraper 10 is arranged in a direction away from the material collection box 1 and is close to the return belt, the air outlet of the wind knife 11 is facing the return belt, and one end thereof is also connected to an air supply pipe 13, a spray rack 16 is installed on the upper part of the material collection box 1, and a plurality of nozzles 17 are arranged on the spray rack 16, and the spray rack 16 is connected to the water supply pipe 12, and a sewage outlet 14 is also arranged on the material collection box 1, and a slide plate 15 is arranged inside the sewage outlet 14 at an angle.

[0027] The working principle of the present invention is as follows: after the return belt drives the roller 2 to rotate clockwise, the gear transmission structure will drive the perforated water pipe 18, the self-cleaning brush roller 9 and the water outlet of the rotary joint 8 to rotate synchronously counterclockwise, and the self-cleaning brush roller 9 cleans the coal slime adhered to the return belt; at this time, the water circuit and the air circuit are opened, and the water medium will pass through the rotary joint 8 and the perforated water pipe 18 in turn, and then fill into the self-cleaning brush roller 9, and finally spray out from the second water outlet 21 of the self-cleaning brush roller 9 under the action of rotation, and the coal slime adhered to the bristles 22 is flushed and cleaned, and at the same time, the dust generation during the cleaning process of the bristles 22 is suppressed; the hard cleaning scraper 10 further scrapes the coal slime remaining on the return belt; finally, the high-speed wind flow sprayed by the wind knife 11 quickly dries the remaining water to prevent the belt from running off due to excessive moisture in the return belt; the cleaned coal slime is collected in the material collection box 1 and discharged through the sewage outlet 14; the spray rack 16 can flush the material collection box 1.

[0028] The self-cleaning brush roller 9 of the present invention has a built-in perforated water pipe 18, which supplies water through a rotary joint 8, ensuring uniform spraying of the water medium during the cleaning process, which not only cleans the coal slime on the bristles 22, but also effectively suppresses the generation of dust during the cleaning process, thereby improving the working environment; the coordinated use of the hard cleaning scraper 10 and the wind knife 11 not only removes the residual coal slime and moisture on the belt, but also avoids the belt deviation caused by excessive moisture, thereby extending the service life of the belt and reducing the operating cost of the coal mine; the provision of the material collection box 1 realizes the centralized collection and treatment of the cleaned coal slime mixture, and promotes the discharge of the coal slime mixture from the sewage outlet 14 through the flushing of the spray rack 16, which not only reduces environmental pollution but also provides the possibility for subsequent resource recovery.
