[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a technical solution: a multi-functional coal sorting device, including a sorting equipment body 1, a primary screening plate 2 fixedly connected inside the sorting equipment body 1, a secondary screening plate 3 fixedly connected inside the sorting equipment body 1, a feed inlet 4 fixedly connected to the top of the sorting equipment body 1, a protective cover 5 installed on the top of the sorting equipment body 1, a first movable groove 6 opened at the top of the protective cover 5, a baffle 7 slidably connected inside the first movable groove 6, structural grooves 8 opened on both sides of the protective cover 5, a limit rod 9 slidably connected inside the structural groove 8, a limit piece 10 fixedly connected to one end of the limit rod 9, through holes 11 opened on both sides of the protective cover 5, the surface of the limit rod 9 slidably connected to the inside of the through hole 11, and several first sliding grooves 12 opened on both sides of the baffle 7. The surface of the positioning rod 9 is slidably connected to the inside of the first chute 12. By installing a protective cover 5 on the top of the sorting equipment body 1, when the sorting equipment body 1 is started to sort coal, the positioning rod 9 is moved out of the through hole 11 and the inside of the first chute 12. At this time, the limit of the baffle 7 is released. The baffle 7 is adjusted to the position that allows the coal to be fed. Then the positioning rod 9 is moved back into the through hole 11 and the inside of the first chute 12, so that the position of the baffle 7 is restricted again. Through this setting, we can ensure that the coal will not splash due to the vibration generated during the mechanical sorting process. This measure effectively prevents gravel and coal particles from splashing onto the workers next to them, thus providing a safer working environment for the workers.

[0023] Reference Figure 3 As shown in this embodiment: the top and bottom ends of the limiting rod 9 are provided with first sliding grooves 12, and the top and bottom ends of one side of the structural groove 8 are fixedly connected with first sliders 13. The surface of the first slider 13 is slidably connected to the inside of the first sliding groove 12. By moving the first slider 13 inside the first sliding groove 12, the movement of the limiting rod 9 can be made more stable, and unnecessary displacement of the limiting rod 9 inside the structural groove 8 can be avoided.

[0024] Reference Figure 3 As shown in this embodiment: a first spring 14 is slidably connected to the surface of the limiting rod 9. One side of the first spring 14 is fixedly connected to the surface of the limiting plate 10, and the other side of the first spring 14 is fixedly connected to the inside of the structural groove 8. By setting the first spring 14, the elasticity of the first spring 14 drives the limiting rod 9 by abutting against the limiting plate 10, so that the limiting rod 9 will not come out of the inside of the first slide groove 12 due to the vibration during the screening of the equipment, thus ensuring the stability of the baffle 7.

[0025] Reference Figure 3 and Figure 4As shown in this embodiment: two second sliding grooves 15 are opened on both sides of the protective cover 5, and two second sliders 16 are fixedly connected to both sides of the baffle 7. The surface of the second slider 16 is slidably connected to the inside of the second sliding groove 15. By moving the second slider 16 inside the second sliding groove 15, the movement position of the baffle 7 can be restricted, providing guidance for the movement of the baffle 7, so that the baffle 7 moves in the expected position, and at the same time, the movement of the baffle 7 is more stable.

[0026] Reference Figure 5 As shown in this embodiment: a viewing slot 17 is provided at the top of the protective cover 5, and a hardened transparent plate 18 is installed inside the viewing slot 17. By setting the hardened transparent plate 18, the staff can intuitively see the working condition inside the equipment when it is running, and promptly discover potential safety hazards or faults, so as to take necessary preventive measures.

[0027] Reference Figure 5 As shown in this embodiment: a second movable groove 19 is provided on both sides of the protective cover 5. A movable plate 20 is slidably connected inside the second movable groove 19. A sliding groove 21 is provided inside the movable plate 20. Several columnar blocks 22 are slidably connected inside the sliding groove 21. The top of the columnar blocks 22 is fixedly connected to the bottom of the cleaning brush 23. By setting the cleaning brush 23, the cleaning brush 23 can slide inside the second movable groove 19, so that the side of the hardened transparent plate 18 facing the protective cover 5 can be cleaned. The cleaning brush 23 can clean the hardened transparent plate 18, remove coal dust, dirt and other impurities attached to the window, and maintain the clarity of the window.

[0028] Reference Figure 5 As shown in this embodiment: a second spring 24 is slidably connected to the surface of the columnar block 22. The top end of the second spring 24 is fixedly connected to the cleaning brush 23, and the bottom end of the second spring 24 is fixedly connected to the bottom end of the sliding groove 21. By making the elasticity of the second spring 24 abut against the cleaning brush 23, the cleaning brush 23 can maintain close contact with the hardened transparent plate 18, thereby improving the cleaning efficiency and effect.

[0029] Working principle: Step 1, install a protective cover 5 on the top of the main body 1 of the sorting equipment to protect the workers from flying coal or gravel during the sorting process. Move the limiting rod 9 out of the through hole 11 and the first slide 12 to release the limit on the baffle 7. Adjust the baffle 7 to the position that allows coal to be fed in, and move the limiting rod 9 back into the through hole 11 and the first slide 12. Use the stable movement of the first slider 13 in the first slide 12 to ensure that the limiting rod 9 will not be displaced in an unnecessary position. At the same time, the elasticity of the first spring 14 drives the limiting rod 9 by abutting the limiting plate 10 to prevent it from coming off due to vibration during equipment screening, thus ensuring the stability of the baffle 7 limit. By setting the second slider 16 to move inside the second slide 15, the movement of the baffle 7 is guided to ensure that the baffle 7 moves stably in the expected position.

[0030] Step 2: A hardened transparent plate 18 is installed on the protective cover 5 as an observation window, so that the staff can see the internal working conditions directly when the equipment is running. A cleaning brush 23 is installed on the side of the hardened transparent plate 18 facing the protective cover 5 and slides inside the second movable groove 19. The cleaning brush 23 is kept in close contact with the hardened transparent plate 18 due to the elastic abutment of the second spring 24.
