Then, by the staff rotating any one of the driving rods 13, at this time, the rotation of the driving rod 13 can drive the rotation of the second bevel gear 12. By the rotation of the second bevel gear 12, the rotation of the first bevel gear 32 can be driven. At this time, because the first bevel gear 32 is threadedly connected to the threaded rod 8, when the first bevel gear 32 rotates, it will generate displacement. At this time, the support ring 14, the sliding block 9 and the positioning block 15 will move synchronously, thereby realizing the movement of the partition plate 5, so that the partition plate 5 can limit the internal coal. Through the above structure, the stability of the coal during transportation is further ensured. And by rotating the driving rod 13, the partition plate 5 can be adjusted according to the actual coal specifications, improving the flexibility of the device, greatly improving the protection effect on the coal, with high practicability and simple operation.

[0027] Furthermore, the connecting component includes an L-shaped connecting rod 19. The L-shaped connecting rod 19 is fixedly connected to the partition plate 5. A clamping block 20 is fixedly connected to the lower surface of the L-shaped connecting rod 19. A clamping groove 16 is formed on the upper surface of the positioning block 15.

Two fan mounting frames 23 are fixedly connected to the front side surface of the protection box 1. Fans 25 are installed inside the two fan mounting frames 23. Collection boxes 24 are arranged on the opposite side surfaces of the two fan mounting frames 23. A linkage component is arranged on the surface of the fan mounting frame 23. When the staff needs to unload coal, first move the sliding block 9 to the frontmost side, then lift the partition plate 5 and take it out of the protection box 1. Subsequently, start the first motor 4 to rotate the blanking plate 3 until it contacts the ground. At this time, an inclined plane is formed. Then start the second motor 21 to drive the rotation of the second threaded rod 31. At this time, the rotation of the second threaded rod 31 can drive the connecting block 30 to slide inside the through groove 6, thereby driving the push plate 18 to move. At this time, the connecting block 30 located inside the sliding groove 7 will also slide, and then the push plate 18 can push the coal inside the protection box 1 out to realize unloading. And through the setting of the linkage component, the fan 25 can be made to suck air. At this time, the dust generated by the coal can be sucked and treated, and the dust will enter the interior of the collection box 24.

[0029] Further, the linkage component includes an L-shaped fixing rod 26. The interior of the L-shaped fixing rod 26 is hollow. The front ends of the guide rod 10 and the second threaded rod 31 respectively rotate through the interiors of the two L-shaped fixing rods 26.

The belt is sleeved and transmitted between the two belt pulleys. The belt slides through the interior of the fan mounting frame 23. Two meshing third bevel gears 29 are arranged inside the L-shaped fixing rod 26. The third bevel gears 29 are respectively sleeved on the outer surfaces of the support rod 27, the guide rod 10 and the second threaded rod 31. By the movement of the driving component, the synchronous rotation of the second threaded rod 31 and the guide rod 10 is driven. At this time, the rotation of the support rod 27 can be driven through the transmission of the third bevel gears 29. Through the rotation of the support rod 27 and the transmission of the second transmission component 28, the rotation of the fan 25 can be realized. Finally, during the movement of the push plate 18, the fan 25 performs dust suction work. Through the setting of the linkage component, the practicability of the device is further improved, and the dust generated during the coal feeding process is reduced as much as possible, so as to avoid the situation that the surrounding staff inhale the floating dust as much as possible. There is no need for the staff to set up additional driving, which saves the production cost and procurement cost and improves the working efficiency of the second motor 21.

[0030] Working principle:

[0031] When the coal loading and unloading protection device is in use, when the staff needs to load coal, first place the coal inside the protection box 1 and separate it through the partition plate 5. Then, the staff rotates any one of the driving rods 13. At this time, the rotation of the driving rod 13 drives the rotation of the second bevel gear 12. The rotation of the second bevel gear 12 drives the rotation of the first bevel gear 32. At this time, because the first bevel gear 32 is threadedly connected to the threaded rod 8, when the first bevel gear 32 rotates, it will generate displacement. At this time, the support ring 14, the sliding block 9 and the positioning block 15 will move synchronously, thereby realizing the movement of the partition plate 5, so that the partition plate 5 can limit the coal inside.

[0032] When the staff needs to unload coal, first move the sliding block 9 to the frontmost side, then lift the partition plate 5 and take it out from the protective box 1. Subsequently, start the first motor 4 to rotate the blanking plate 3 until it contacts the ground, forming an inclined plane at this time. Then start the second motor 21 to drive the rotation of the second threaded rod 31. At this time, through the rotation of the second threaded rod 31, the connecting block 30 can be driven to slide inside the through groove 6, thereby driving the push plate 18 to move. At this time, the connecting block 30 located inside the sliding groove 7 will also slide, so as to realize the unloading of the coal inside the protective box 1 by the push plate 18. And through the setting of the linkage component, the fan 25 can be made to suck air, and at this time, the dust generated by the coal can be vacuumed. The dust will enter the inside of the collection box 24.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
