[0021] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0022] As Figures 1-4 shown, a coal loading automatic anti-leakage device for coal mines includes a support 1 and a conveyor mechanism 2 arranged on the support 1 for conveying coal into the coal truck, and a guide mechanism 3 for assisting the coal to enter the truck. The conveyor mechanism 2 includes a conveyor seat 21 fixedly connected to the upper end of the support 1. A conveyor belt 22 for conveying coal is arranged in the conveyor seat 21. A bottom plate 23 is fixedly connected to the lower end of the conveyor seat 21. The length of the bottom plate 23 is slightly shorter than the length of the conveyor seat 21. A connection assembly 24 is arranged at one end of the bottom plate 23. A scratching assembly 25 for cleaning the conveyor belt 22 to prevent coal slag from adhering and falling on the ground or equipment is arranged in the connection assembly 24.

[0023] In this embodiment, when loading coal into the coal truck, the conveyor belt 22 drives the coal to move towards the coal truck. When the coal moves to the end of the conveyor belt 22 close to the coal truck, it falls from the conveyor belt 22 onto the guide mechanism 3, and then the coal enters the truck through the guidance of the guide mechanism 3, preventing the coal from falling outside the truck when it falls from the conveyor belt 22. The scratching assembly 25 scratches the lower part of the conveyor belt 22, so that the coal adhering to the conveyor belt 22 falls into the connection assembly 24, and then slides from the connection assembly 24 to the guide mechanism 3 and enters the coal truck along with the guidance of the guide mechanism 3, preventing the coal from adhering to the conveyor belt 22 and falling on the ground or equipment, resulting in leakage.

[0024] As Figure 5 and Figure 6 shown, the connection assembly 24 includes a connection frame 241 fixedly connected to one end of the bottom plate 23. A fixed plate 242 is fixedly arranged below the connection frame 241. The fixed plate 242 is in an inclined state.

[0025] The scraping assembly 25 includes cross bars 251 fixedly connected to both sides inside the connection frame 241. One end of each cross bar 251 is fixedly connected with a limiting plate 252. A slider 253 is arranged between the two cross bars 251. Sliding grooves 254 are formed on both sides of the slider 253, and the slider 253 slides on the cross bars 251 through the sliding grooves 254. A scraping plate 255 for scraping cinder on the conveyor belt 22 is fixedly arranged at the upper end of the slider 253. One side of the slider 253 is rotatably connected with a rotating rod 256. The other end of the rotating rod 256 is provided with two rotating rollers 257. A plurality of striking convex bars are fixedly arranged on the surface of the rotating rollers 257. The other end of the rotating rod 256 is rotatably connected to one side of the rotating roller 257 near the edge. The rotating roller 257 is rotatably connected inside the connection frame 241. A driving element 258 is arranged on one side of one rotating roller 257 for providing the rotational power for the rotating roller 257.

[0026] The guiding mechanism 3 includes a guiding frame 31 fixedly connected to one side of the lower end of the connection frame 241. A connection shell 32 is fixedly connected below the guiding frame 31. A rotating disk 33 is arranged inside the connection shell 32. A striking plate 34 for striking below the guiding frame 31 is fixedly arranged on the outer side of the rotating disk 33. A motor for driving the rotating disk 33 to rotate is arranged on the outer side of the connection shell 32.

[0027] In this embodiment, when the conveyor belt 22 drives the coal to move towards the coal truck, the coal moves with the conveyor belt 22 to one end of the conveyor belt 22 and then falls off the conveyor belt 22. The coal falls from the conveyor belt 22 onto the guiding frame 31. To prevent the coal from adhering to the guiding frame 31, the motor on one side of the connection shell 32 works to drive the rotating disk 33 to rotate. The rotating disk 33 drives the striking plate 34 to rotate. When the striking plate 34 rotates, it strikes below the guiding frame 31, causing the coal adhering to the guiding frame 31 to separate from the guiding frame 31 and fall into the coal truck. While the conveyor belt 22 is conveying the coal, the driving element 258 works to drive the rotating roller 257 to rotate. The rotating roller 257 pulls the rotating rod 256. Through the rotation of the rotating roller 257, the rotating rod 256 reciprocally pushes and pulls the slider 253. The slider 253 drives the scraping plate 255 to scrape below the conveyor belt 22, causing the coal adhering to the conveyor belt 22 to fall onto the fixing plate 242. When the rotating roller 257 rotates, it drives the striking convex bars to strike the fixing plate 242, causing the coal on the fixing plate 242 to fall onto the guiding frame 31 along the slope of the fixing plate 242 and then fall into the coal truck along the slope of the guiding frame 31. This reduces the situation where the coal adheres to the conveyor belt 22 due to moisture, resulting in coal leaking onto the equipment or the ground, and reduces the impact on the working environment.
