[0020] See also Figures 1 to 7 The present invention provides an environmental purification and dust removal device for coal mine mining, comprising a movable mobile frame 1, a suction pipe 2 fixedly connected to the mobile frame 1, a collecting mechanism 3 fixedly connected to the bottom end of the mobile frame 1, the suction pipe 2 is fixedly connected to one end of the collecting mechanism 3, a humidifying mechanism 4 is fixedly connected to the inner wall of the mobile frame 1 above the collecting mechanism 3, and one end of the humidifying mechanism 4 extends into the suction pipe 2.

[0021] The humidifying mechanism 4 is provided to moisten the dust sucked in through the suction pipe 2, so that the dust can be settled more easily, which is convenient for collection and treatment, thereby avoiding dust from being raised again during coal mining. The collecting mechanism 3 is provided to collect the sucked dust, so that the dust can be easily cleaned. At the same time, since dust and coal powder account for a large proportion in coal mining, the collection of the dust is convenient for the recycling of the coal powder in the dust. The collecting mechanism 3 can compress the dust to reduce its volume for easy transportation.

[0022] See also Figures 2 to 4 、 Figure 6 and Figure 7, the collecting mechanism 3 includes a fixed box 5 fixedly connected to the bottom end of the mobile frame 1, a compression box 6 is symmetrically installed in the fixed box 5, and a connecting cavity 7 is formed between one side of the two compression boxes 6 and the fixed box 5, and the side wall of each compression box 6 is provided with a mounting groove 8, and a filter screen 9 is installed in the mounting groove 8. A connecting through groove 10 is provided on the side of the compression box 6 opposite to the connecting cavity 7, and a connecting through groove 10 is provided. One side of the compression box 6 is fixedly connected to a connecting pipe 11, and the other end of the connecting pipe 11 is fixedly connected to another compression box 6. The connecting pipe 11 is provided with a closed opening 12, and a closing plate 13 is slidably connected to the closed opening 12. One side of the closing plate 13 is fixedly connected to a first rack 14, and the compression box 6 is rotatably connected to a first rotating shaft 15 on one side close to the first rack 14. The first rotating shaft 15 is fixedly connected to a driving gear 16, and the first rotating shaft 15 extends to one end of the compression box 6 and is fixedly connected to a toggle rod 17. A compression assembly 18 for compressing dust is installed on one of the compression boxes 6.

[0023] See also Figure 4 The compression assembly 18 includes a rotation groove 19 on both sides of the compression box 6, and a threaded rod 20 is rotatably connected in the rotation groove 19. The threaded rod 20 is threadedly connected with a sliding block 21, and the sliding block 21 is fixedly connected to a pressure plate 22. The compression box 6 is fixedly connected to a motor 23 on the side close to the threaded rod 20, and the output end of the motor 23 is fixedly connected to the threaded rod 20. One side of the compression box 6 is rotatably connected to a second rotating shaft 24, and a rotating plate 25 is fixedly connected to the second rotating shaft 24. One end of the second rotating shaft 24 is fixedly connected to a half gear 26, and a second rack 27 is fixedly connected to the position corresponding to the pressure plate 22 and the half gear 26.

[0024] During the dust removal operation, the dust is sucked into the fixed box 5 through the suction pipe 2 and enters the connecting cavity 7. In the initial state, the rotating plate 25 is in an inclined state, and the rotating plate 25 does not close the connecting groove 10. The connecting cavity 7 is connected to the interior of the compression box 6. After the dust enters the connecting cavity 7, it will enter the compression box 6 through the connecting groove 10 and then be filtered by the filter 9, so that the dust is filtered and accumulated in the compression box 6. The motor 23 is started, and the motor 23 will drive the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the sliding block 21 to move. The movement of the sliding block 21 drives the pressure plate 22 to move. The movement of the pressure plate 22 will press the compression box 6. The dust in the box 6 is compressed to reduce the volume of the dust, making the dust more compact, which is convenient for collecting and subsequently transporting the dust. When the pressing plate 22 moves, the pressing plate 22 will drive the second rack 27 to move, and the movement of the second rack 27 will drive the half gear 26 to rotate. The rotation of the half gear 26 drives the second rotating shaft 24 to rotate, and the rotation of the second rotating shaft 24 drives the rotating plate 25 to rotate. The rotation of the rotating plate 25 will close the connecting groove 10, so that the dust no longer enters the compression box 6, preventing the dust in the compression box 6 from being raised, thereby facilitating the compression of the dust. When the pressing plate 22 is compressed, it will simultaneously drive the toggle rod 17 to rotate, and the rotation of the toggle rod 17 drives the first A rotating shaft 15 rotates, the first rotating shaft 15 rotates to drive the driving gear 16 to rotate, the driving gear 16 rotates to drive the first rack 14 to move, the first rack 14 moves to drive the closing plate 13 to move, the closing plate 13 is stepped, in the initial state, the closing plate 13 blocks one side of the connecting pipe 11, so that the filtered air in one of the compression boxes 6 flows out through the connecting pipe 11, when compression is performed, the closing plate 13 moves, the closing plate 13 blocks the outer wall of the connecting pipe 11 at the closed port 12, and the other side of the closing plate 13 does not block the inner wall of the connecting pipe 11, so that the connecting pipe 11 connects the two compression boxes 6, at this time the dust Dust-laden air continues to enter the connecting cavity 7, increasing the pressure in the connecting cavity 7, thereby pushing the partition plate 31 to overcome the rotation of the spring 32, allowing the dust to enter the adjacent compression box 6, and pass through the filter 9 to allow the air to enter the connecting pipe 11, and then enter the adjacent compression box 6, and back-blow the filter 9 in the compression box 6, so that the dust on the filter 9 is cleaned up, and flows out of the compression box 6 with the air flow, thereby increasing the service life of the filter 9, increasing the service time of the equipment, and flowing into the external environment. Because this part of dust is less, it has less impact on the dust content in the environment, and can be collected and compressed again as the dust removal work proceeds.

[0025] See also Figure 1The humidifying mechanism 4 includes a spray pipe 28 fixedly connected to the upper inner wall of the mobile frame 1, and a nozzle is fixedly connected to the spray pipe 28. One end of the nozzle extends into the suction pipe 2. The spray pipe 28 is connected to an external water pump. The water pump transmits water to the nozzle through the spray pipe 28 to humidify the dust in the suction pipe 2, making the dust more easily condensed, which is convenient for subsequent compression and collection.

[0026] See also Figure 1 One end of the suction pipe 2 is fixedly connected to the pump, and the other end of the suction pipe 2 is communicated with the fixed box 5. The end of the suction pipe 2 located outside the mobile frame 1 is in a trumpet shape. The dust is sucked into the suction pipe 2 through the pump. The trumpet shape of the suction pipe 2 makes the dust move faster at the end of the suction pipe 2, impacting the water sprayed from the nozzle, so that the water can be further atomized and in closer contact with the dust, making it easy for the dust to settle and facilitating the condensation and compression of the dust.

[0027] See also Figure 2 The two compression boxes 6 are fixedly connected at one end close to the connecting cavity 7 through a connecting plate 30, so that the connecting cavity 7 becomes a relatively closed cavity.

[0028] See also Figure 2 and Figure 5 The connecting cavity 7 is connected to the two compression boxes 6. A partition plate 31 is rotatably connected in the connecting cavity 7. A spring 32 is fixedly connected between the partition plate 31 and the inner wall of the connecting cavity 7.

[0029] The connecting cavity 7 temporarily stores dust. When the rotating plate 25 is not opened, the relatively closed connecting cavity 7 can ensure that the pressure in the connecting cavity 7 increases when dust continues to enter, thereby pushing the partition plate 31 to rotate and allowing the dust to enter the other compression box 6.

[0030] See also Figure 4 The second rack 27 is meshed with the half gear 26. A contact rod 33 is fixedly connected to one side of the second rack 27. The contact rod 33 contacts the rotating plate 25. When the second rack 27 moves, it drives the half gear 26 to rotate, so that the rotating plate 25 blocks the connecting groove 10. When the second rack 27 moves, it drives the contact rod 33 to move, and the contact rod 33 contacts the rotating plate 25, so that the rotating plate 25 keeps blocking the connecting groove 10.

[0031] One end of the toggle rod 17 extends into the compression box 6 and abuts against the pressure plate 22. During compression, the movement of the pressure plate 22 can drive the toggle rod 17 to move, so that the closing plate 13 does not block the connecting pipe 11, thereby connecting the two compression boxes 6 through the connecting pipe 11.

[0032] See also Figure 6The driving gear 16 is engaged with the first rack 14 , and the driving gear 16 rotates to drive the first rack 14 to move, thereby driving the closing plate 13 to move.
