[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] Reference Figures 1-6As shown, a coal conveying device with a cleaning function includes two front and rear fixed plates 1, and support legs 2 are fixedly installed on the left and right sides of the lower ends of the two fixed plates 1. Two rotating rollers 3 are rotatably installed between the two fixed plates 1. A conveyor belt 4 is connected to the two rotating rollers 3 by transmission. A cleaning component 7 and a dust suction component 8 are provided at the lower end of the conveyor belt 4. The dust suction component 8 is located on the left side of the cleaning component 7. After the cleaning component 7 is used to clean the surface of the conveyor belt 4, the dust suction component 8 is used to perform secondary dust removal on the surface of the conveyor belt 4. The cleaning component 7 includes two A fixing block 701, two first fixing blocks 701 are fixedly connected to the lower ends of the two fixing plates 1 respectively, and the front ends of the two first fixing blocks 701 are penetrated to form a limiting groove 702. A cleaning brush 703 is placed inside the limiting groove 702. The upper end of the cleaning brush 703 abuts against the surface of the conveyor belt 4. The cleaning brush 703 is installed inside the limiting groove 702 by a locking bolt 704 and a nut 705. After long-term use, the cleaning brush 703 will be worn. The worn cleaning brush 703 cannot fully contact the surface of the conveyor belt 4, reducing The thoroughness of cleaning may cause residue accumulation. By rotating the two locking bolts 704 and nuts 705, they can be taken out from the inside of the limiting groove 702 opened inside the first fixing block 701 and then replaced. The dust collection assembly 8 includes two second fixing blocks 801, and the two second fixing blocks 801 are fixedly connected to the lower ends of the two fixing plates 1 respectively. A dust collecting cover 802 is fixedly connected between the two fixing plates 1. The rear end of the rear fixing plate 1 is fixedly connected to a collection box 803. The right end of the collection box 803 is fixedly connected to a connecting pipe 805. The other end of the connecting pipe 805 is connected to the interior of the dust collecting hood 802. A fan 804 is provided at the upper end of the collecting box 803. The input end of the fan 804 is connected to the interior of the collecting box 803. The cleaning brush 703 can be used to remove most of the residues on the surface of the conveyor belt 4, but some fine coal dust may still remain.

After the coal on the upper surface of the conveyor belt 4 is transported from one place to another, the part that has touched the coal will move downward, and the surface of the conveyor belt 4 is cleaned by the cleaning brush 703 provided at the lower end. The coal swept from the surface of the conveyor belt 4 will fall into the inside of the collection box 905. After long-term use, the bristles of the cleaning brush 703 will gradually wear out and lose its elasticity and cleaning effect. By rotating the locking bolts 704 threadedly connected between the two first fixed blocks 701, it can be removed from the inside of the first fixed block 701, and the cleaning brush 703 can be taken out for replacement. The dust collecting cover 802 provided on the left side of the cleaning brush 703 performs secondary cleaning on the part cleaned by the cleaning brush 703, and cooperates with the connecting pipe 805, the fan 804 and the collection box 803 to transport the absorbed coal to the inside of the collection box 803, ensuring a more thorough cleaning effect.
