[0002] Belt conveyors are a common material conveying equipment, widely used in industries such as mining, construction, chemical, metallurgy, and grain. They are mainly composed of conveyor belts, conveyor belt rollers, idlers, tensioning devices, drive devices, and support devices.

[0003] In actual operation, belt conveyors not only accumulate impurities from goods but also a large amount of external dust, affecting the reliability of belt conveyor operation and causing a significant decrease in work efficiency. Therefore, it is necessary to clean belt conveyors regularly or install cleaning devices on belt conveyors to clean the conveyor belt in real time.

[0004] A search revealed that Chinese utility model patent CN220501859U discloses "a belt conveyor", which includes a frame, two axles, two drive wheels and a drive belt. The two axles are rotatably mounted on both ends of the frame, and the two drive wheels are fixed on the two axles. The two drive wheels are connected by a drive belt. The frame is provided with a cleaning component, a guiding component and a driving component.

[0005] In the prior art, including the belt conveyors mentioned above, the cleaning components are used to clean the conveyor belt. Although this can achieve a certain cleaning effect, in actual use, because the conveyor belt is usually soft and lacks limiting support at the location of the cleaning components, there is a problem that the belt cannot make full contact with the brush bristles and thus cannot be cleaned thoroughly.
