[0002] A scraper conveyor for coal mines is a key piece of equipment specifically designed for transporting coal in underground coal mining. It uses a chain-driven scraper to continuously transport coal within a closed chute. Suitable for horizontal or slightly inclined roadway environments, it requires regular cleaning.

[0003] For example, a scraper conveyor for coal mine transportation with coal powder cleaning function, as disclosed in announcement number CN220866325U, belongs to the field of coal transportation technology. It includes a conveyor frame, with sprockets rotatably mounted at both ends inside the frame. A support partition is fixed in the middle of the conveyor frame, located between two sets of sprockets. A drive motor is installed on one side of the discharge end of the conveyor frame, and the output end of the drive motor is connected to the end of the sprockets. A chain is arranged between the sprockets, and scrapers are evenly installed on the outer side of the chain. The brush roller at the front end of the conveyor frame of this utility model, used in conjunction with a transmission mechanism consisting of a drive pulley, a driven pulley, and a belt, can drive the brush roller to rotate while the drive motor controls the sprockets to rotate, cleaning the scrapers conveyed below the conveyor frame, preventing coal powder from accumulating at the bottom of the conveyor frame, reducing conveying resistance during use, and making it more energy-efficient. However, because this scraper conveyor for coal mine transportation can only clean the scrapers, it cannot clean and maintain the chain on the scraper, which easily leads to chain wear.

[0004] Therefore, a cleaning device for scraper conveyors used in coal mine transportation has now been developed, which can clean and maintain the chains on the scraper conveyor and prevent scraper conveyor failure. Utility Model Content
