[0037] The cleaning device includes a plurality of cleaning components 1 sequentially distributed along the conveying direction of the conveyor belt 202 of the belt conveyor 20, and at least three cleaning components 1 respectively include a scraper 11, a cleaning brush 12 and a nozzle 13 for ejecting airflow, the scraper 11 and the cleaning brush 12 can contact with the working surface 2021 to clean the conveyor belt 202, and the nozzle 13 can eject a cleaning airflow toward the working surface 2021 to clean the conveyor belt 202. The scraper 11, the cleaning brush 12 and the nozzle 13 can sequentially clean large particles or large-volume materials on the working surface 2021, small particles or small-volume materials attached to the working surface 2021 of the conveyor belt 202, and extremely fine dust, etc. The three different cleaning structures can more thoroughly clean the working surface 2021 of the conveyor belt 202, thereby improving the cleaning effect of the belt conveyor 20. There are less residual materials and dust on the conveyor belt 202, and the possibility of the conveyor belt 202 continuously dropping materials and generating dust during transportation is small. There is no need to perform more thorough cleaning of the belt conveyor 20 and the location where it is located, which can effectively improve the cleaning effect of the belt conveyor 20.

[0038] In some embodiments, the cleaning brush 12 is located between the scraper 11 and the nozzle 13. The cleaning brush 12 is located between the scraper 11 and the nozzle 13, and can play a good receiving role, effectively clean the impurities or materials with a medium volume, improve the cleaning effect of the conveyor belt 202, and improve the cleaning effect of the belt conveyor 20.

[0039] It should be noted that the arrangement order of the cleaning brush 12, the scraper 11 and the nozzle 13 can also be adjusted.

[0041] In some embodiments, the nozzle 13 is directed toward one end of the conveyor belt 202 along the conveying direction. The nozzle 13 can be directed toward the material being transported on the conveyor belt. When the conveyor belt transports the material, the nozzle 13 can clean the material along the conveying direction of the material, thereby reducing the pressure and cost required for cleaning the material, and also facilitating improving the cleaning effect of the conveyor belt.

[0042] It should be noted that one end of the conveyor belt may be the end of the conveyor belt close to the driving wheel.

[0043] In some embodiments, the distances of the scraper 11, the cleaning brush 12 and the nozzle 13 relative to the conveyor belt 202 are adjustable. The distance is adjustable, and the cleaning effect of the scraper 11, the cleaning brush 12 and the nozzle 13 on the conveyor belt 202 can be adjusted according to actual conditions. When the scraper 11 or the cleaning brush 12 is worn, the scraper 11 and the cleaning brush 12 can also be adjusted to make the scraper 11, the cleaning brush 12 and the conveyor belt 202 fit more closely, so as to ensure the cleaning effect and extend the service life of the scraper 11 and the cleaning brush 12.

[0044] In some embodiments, the cleaning assembly 1 further includes a support member 14 spanning the conveyor belt 202 and having an adjustable distance relative to the conveyor belt 202 , and the support member 14 is connected to the scraper 11 , the cleaning brush 12 or the nozzle 13 .
