A base plate 2 is fixed between the bottoms of the side plate 1. The interior of the base plate 2 is inclined, and a discharge port is opened at the end of the base plate 2. A collection frame 26 is engaged with the discharge port on the surface of the base plate 2. The surface of the base plate 2 is connected to the collection frame 26 by positioning bolts 27 to facilitate disassembly and assembly, so that the collection frame 26 can collect coal fragments falling from the base plate 2. At the same time, the use of positioning bolts 27 facilitates the installation and disassembly of the collection frame 26. A drive motor 3 is fixed on the upper side of one side of the side plate 1, and the output end of the drive motor 3 is fixed. A main shaft 4 is fixed, and a drive roller 5 is fixed through the middle of the two sets of side plates 1. The other end of the two sets of side plates 1 is rotatably connected to a driven shaft 6, and a driven roller 7 is fixed on the surface of the driven shaft 6. The drive roller 5 and the driven roller 7 are connected by a conveyor belt 8, and toothed blocks 9 are evenly fixed at both ends of the inner surface of the conveyor belt 8. Rubber side belts 11 are fixed at both ends of the surface of the conveyor belt 8. Transmission gears 10 are fixed at both ends of the main shaft 4 and the driven shaft 6. The transmission gears 10 and the toothed blocks 9 inside the conveyor belt 8 form a meshing connection, so that the transmission gears 10 on the drive shaft 4 can drive the toothed blocks 9 below the conveyor belt 8 to mesh and drive the conveyor belt 8.

[0022] Please see Figure 1-5A recessed frame 12 is fixed on the upper side of the side plate 1 near the drive motor 3, and a feed inlet 13 is connected to the upper part of the recessed frame 12. Side covers 14 are fixed to the ends of the two sets of side plates 1. An internal block 28 is fixed inside the upper part of the side cover 14, and one end of the internal block 28 is inclined. A toothed blade 29 that is offset from the toothed head on the crushing roller 16 is fixed on the surface of the internal block 28. The crushing roller 16 can be used in conjunction with the toothed blade 29 on the internal block 28 to facilitate the crushing of large pieces of coal entering the conveyor. A rotating shaft 15 is rotatably connected to the recessed frame 12, and a crushing roller 16 is fixed on the surface of the rotating shaft 15. A first gear 17 is fixed to the outer end of the rotating shaft 15 on the surface of the recessed frame 12. A second gear 18 that meshes with the first gear 17 is fixed to the outer end of the main connecting shaft 4. A connecting shaft 19 is rotatably connected to the surface of the side plate 1, and the connecting shaft 19 is connected to the main connecting shaft. The four components are connected by a transmission belt 20. A cam 21 located at the inner end of the transmission belt 20 is fixed on the surface of the connecting shaft 19. A slot 22 is opened on the surface of the side plate 1, and a movable plate 23 is provided on the slot 22. The movable plate 23 and the slot 22 on the surface of the side plate 1 form a snap-fit ​​sliding connection. Both ends of the movable plate 23 are connected to one side of the slot 22 on the surface of the side plate 1 through springs 24. The right end face of the movable plate 23 is attached to the end of the cam 21. The rotation of the cam 21, in conjunction with the use of the spring 24, can easily drive the movable plate 23 to bounce on the slot 22. A cleaning brush 25 is attached to the upper part of the movable plate 23, and the upper end face of the cleaning brush 25 is attached to the lower end face of the conveyor belt 8. The cleaning brush 25 on the surface of the movable plate 23 can brush the lower surface of the conveyor belt 8, thereby improving the cleanliness of the conveyor belt 8.

[0023] Working principle: First, when in use, coal is discharged into the concave frame 12 through the feed port 13 so that the crushing roller 16 inside the concave frame 12 can work with the toothed blades 29 on the surface of the built-in block 28 to crush the large pieces of coal and improve the conveying effect of the device. When the conveying device is in operation, the second gear 18 on the surface of its drive shaft 4 will drive the first gear 17 on the surface of the rotating shaft 15 to mesh and rotate so that the crushing roller 16 can rotate and crush the coal.

[0024] When the drive shaft 4 rotates, it drives the connecting shaft 19 to rotate via the transmission belt 20. This causes the cam 21 on the surface of the connecting shaft 19 to rotate and press the movable plate 23, allowing the movable plate 23 to slide on the slot 22 on the surface of the side plate 1. With the help of the spring 24, the movable plate 23 can move back and forth on the slot 22 on the surface of the side plate 1. This facilitates the cleaning brush 25 on the surface of the movable plate 23 to brush the lower surface of the conveyor belt 8, preventing coal debris from adhering to the conveyor belt 8. The falling coal debris will slide through the inclined surface of the bottom plate 2 into the collection frame 26 for collection. The collection frame 26 is fixed to the bottom plate 2 by positioning bolts 27 for easy installation and removal. This is the operating principle of the conveying transmission device used in this coal mine project.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
