Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1

[0019] Please refer to Figures 1 - 3 , a coal mine electromechanical transportation transmission device shown in the figure, including a frame 1, a scraping component and a cleaning component. A conveyor belt 2 is provided between the frames 1. The two ends inside the conveyor belt 2 are connected to the conveyor wheels 3, and the two ends of the conveyor wheels 3 are connected to the frame 1. The scraping component includes U-shaped frames 4 installed on both sides of the frame 1. Scrapers 5 are fixedly provided at both ends of the U-shaped frame 4, and the scrapers 5 are located below the conveyor belt 2. The cleaning component includes placing plates 6 provided on the U-shaped frame 4 and having a quantity of two. Brushes 7 in contact with the conveyor belt 2 are fixedly provided on one side above the placing plates 6. U-shaped rods 8 are provided at the ends of each placing plate 6. Rack plates 9 are fixedly provided in the middle of the U-shaped rods 8. Gears 10 are meshed between the two rack plates 9. A rotating shaft 11 is fixedly provided on one side of the gear 10. The other end of the rotating shaft 11 is rotatably connected to the bracket 12, and both ends of the bracket 12 are fixedly connected to the frame 1. And one side of one of the rack plates 9 is connected to a driving member.

[0020] Please refer to Figure 3 , the driving member shown in the figure includes a pushing groove 13 fixedly provided on one side of one of the rack plates 9. A Z-shaped rotating rod 14 is slidably provided inside the pushing groove 13. The other end of the Z-shaped rotating rod 14 is connected to the output end of the first motor 15.

[0021] When using the electromechanical transportation drive device in coal mines: First, place the frame 1 at the position where coal needs to be transported in the coal mine. Then, start the conveyor belt 2. The start of the conveyor belt 2 can realize the transportation of the coal placed on the conveyor belt 2. When the conveyor belt 2 transports coal, the transported coal will fall from one end of the conveyor belt 2. However, wet coal particles will adhere to the surface of the conveyor belt 2. As the conveyor belt 2 continues to move, when the conveyor belt 2 moves to one side of the U-shaped frame 4 under the frame 1, the scraper 5 installed between the U-shaped frames 4 will scrape off the wet coal particles adhering to the surface of the conveyor belt 2. The scraped coal particles will fall from the scraper 5, reducing the adhesion of coal particles on the conveyor belt 2, reducing the weight of its own load during the transportation of the conveyor belt 2, avoiding the overuse of the driving equipment, and increasing the safety of use;

[0022] After the scraper 5 scrapes off the coal particles on the conveyor belt 2, the first motor 15 starts. The start of the first motor 15 can drive the Z-shaped rotating rod 14 at the output end to rotate. The rotation of the Z-shaped rotating rod 14 can push the push groove 13 on one side of one of the rack plates 9 at its other end. The movement of the push groove 13 can drive the movement of the rack plate 9. The movement of the rack plate 9 can meshingly drive the gear 10 to rotate. Since the other rack plate 9 meshes with the other side of the gear 10, it can drive the movement of the other rack plate 9, thus realizing the forward or reverse movement between the two rack plates 9. The movement of the rack plate 9 can drive the movement of the U-shaped rod 8. Since the end of the U-shaped rod 8 is connected to the end of the placement plate 6, it can drive the movement of the placement plate 6, realizing the forward or reverse movement of the two placement plates 6 on the U-shaped frame 4. When the placement plates 6 move forward or in the opposite direction, the brush 7 on one side can clean the outer surface of the conveyor belt 2, realizing the cleaning of the coal particles that are not completely scraped off on the conveyor belt 2, effectively improving the cleanliness of the surface of the conveyor belt 2. After the coal particles are cleaned, they will fall under the action of gravity. A loading container is placed under the frame 1 when the coal particles fall, which can collect the fallen coal particles, prevent the fallen coal particles from scattering on the ground, increase the convenience of collecting coal particles, and reduce the later cleaning of coal particles by the staff;

[0023] The device has a simple structure. By adding a scraping component and a cleaning component, it can scrape and clean the coal particles adhering to the outer surface of the conveyor belt 2, increasing the cleanliness of the surface of the conveyor belt 2. The cleaning component, when used in cooperation with the driving part, can realize the reciprocating movement of the brush 7 under the conveyor belt 2, improving the working efficiency of cleaning the surface of the conveyor belt 2, avoiding the weight overload caused by the adhesion of coal particles during the transportation of the conveyor belt 2, increasing the safety of use, and avoiding the reduction of the coal transportation efficiency caused by the shutdown of the transportation drive device for cleaning the coal particles on the conveyor belt 2, effectively improving the efficiency of cleaning the conveyor belt surface.
