[0017] By adopting the above technical solution, it is ensured that the drill rod can fully crush the coal mine.

[0018] To sum up, the beneficial technical effects of the present utility model are as follows:

[0019] 1. When the present utility model transports coal mines, the feed hopper can be used to receive coal mines. During this process, the first water pipe is used to convey water, and the water is sprayed out from a plurality of first atomizing nozzles. At this time, the sprayed misty water can effectively block the upper port of the feed hopper, effectively avoid the dust in the feed hopper from floating out, and can effectively play a role in suppressing dust. Then, the coal mines falling into the feed hopper finally fall on one end of the belt conveyor. The rotation of the belt conveyor can effectively drive the movement of the coal mines, so that the coal mines can pass through the lower part of the second atomizing nozzle. At this time, the misty water sprayed out from the second atomizing nozzle can perform anti-dust operation at the discharge port of the feed hopper, and can also spray and cool the coal mines, improving the stability of coal mine transportation. The overall anti-dust effect is good, and at the same time, the structure is simple and convenient for installation and maintenance;

[0020] 2. When the present utility model receives coal mines, when a relatively large coal mine gets stuck inside the feed hopper, a plurality of hydraulic rods are synchronously started. At this time, the hydraulic rods start to contract. Under the linkage of the linkage seat, a plurality of drill rods start to enter the inside of the feed hopper. Since the drill rods on both sides of the feed hopper are alternately distributed, the mutually approaching drill rods can effectively crush the large-volume coal mine, effectively break the large-volume coal mine into small-volume coal mines, and effectively ensure the stable transportation of the coal mines. The overall functionality and practicability are effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following further elaborates on the method of the present utility model in conjunction with the attached drawings.

[0025] Refer to Figure 1 、 Figure 2 , a coal mine transportation device for underground coal mining and dust prevention, including a belt conveyor 1. One end of the belt conveyor 1 is fixedly connected with a feed hopper 2. A first water conduit 3 is installed on each of the symmetrical side surfaces of the belt conveyor 1. A plurality of first atomizing nozzles 4 are fixedly installed outside the first water conduit 3. The plurality of first atomizing nozzles 4 are distributed at the symmetrical two side positions of the upper opening of the feed hopper 2. A plurality of second water conduits 5 are communicated outside the two first water conduits 3. The second water conduits 5 are in a C shape. A plurality of second atomizing nozzles 6 are fixedly installed outside the second water conduits 5. The spraying direction of the second atomizing nozzles 6 is aligned with the conveying surface of the belt conveyor 1. The spraying direction of the first atomizing nozzles 4 is symmetrically inclined above the opening of the feed hopper 2. During the transportation of coal, the feed hopper 2 can be used to receive coal. During this process, water is conveyed through the first water conduit 3 and ejected from the plurality of first atomizing nozzles 4. At this time, the ejected misty water can effectively seal the upper port of the feed hopper 2, effectively prevent the dust in the feed hopper 2 from floating out, and achieve an effective dust suppression effect. Then, the coal falling into the interior of the feed hopper 2 finally lands at one end of the belt conveyor 1. The rotation of the belt conveyor 1 can effectively drive the movement of the coal, enabling the coal to pass under the second atomizing nozzles 6. At this time, the misty water ejected from the second atomizing nozzles 6 can perform dust prevention operations at the discharge port of the feed hopper 2, and can also spray and cool the coal, improving the stability of coal transportation. The overall dust prevention effect is good, and at the same time, the structure is simple and convenient for installation and maintenance.

[0026] Refer to Figure 1, on the outer surfaces of the symmetric two sides of the feeding hopper 2, two hydraulic rods 8 are respectively and fixedly installed. The telescopic ends of the two hydraulic rods 8 with the same telescopic direction are fixedly connected with a linkage seat 9. On the inner side surface of the linkage seat 9, multiple drill rods 10 are fixedly connected. On the two side surfaces of the feeding hopper 2, multiple through holes are provided. One end of the drill rod 10 corresponds to the position of the through hole. The multiple drill rods 10 on the two sides of the feeding hopper 2 are alternately distributed. Among them, when receiving coal mines, when a relatively large coal mine gets stuck inside the feeding hopper 2, multiple hydraulic rods 8 are synchronously started. At this time, the hydraulic rods 8 start to contract. Under the linkage of the linkage seat 9, multiple drill rods 10 start to enter the inside of the feeding hopper 2. Since the drill rods 10 on the two sides of the feeding hopper 2 are alternately distributed, the mutually approaching drill rods 10 can effectively crush the large-volume coal mine, can effectively break the large-volume coal mine into small-volume coal mines, and can effectively ensure the stable transportation of the coal mine. The overall functionality and practicality are effectively improved.

[0027] Working principle: During use, first install the device at a designated position, and then use the feeding hopper 2 to receive coal mines. During this process, use the first water conduit 3 to convey water and make the water spray out from multiple first atomizing nozzles 4. At this time, the sprayed misty water can effectively block the upper port of the feeding hopper 2, can effectively prevent the dust in the feeding hopper 2 from floating out, and can play an effective role in suppressing dust. Then the coal mines falling into the inside of the feeding hopper 2 finally fall on one end of the belt conveyor 1. The rotation of the belt conveyor 1 can effectively drive the movement of the coal mines, so that the coal mines can pass under the second atomizing nozzle 6. At this time, the misty water sprayed out from the second atomizing nozzle 6 can perform anti-dust operation on the discharging port of the feeding hopper 2, and can also spray and cool the coal mines, improving the stability of coal mine transportation. During the whole transportation process, when a relatively large coal mine gets stuck inside the feeding hopper 2, multiple hydraulic rods 8 are synchronously started. At this time, the hydraulic rods 8 start to contract. Under the linkage of the linkage seat 9, multiple drill rods 10 start to enter the inside of the feeding hopper 2. Since the drill rods 10 on the two sides of the feeding hopper 2 are alternately distributed, the mutually approaching drill rods 10 can effectively crush the large-volume coal mine, can effectively break the large-volume coal mine into small-volume coal mines, and can effectively ensure the stable transportation of the coal mine.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
