[0029] AsFigures 1-4 As shown, the coal mine belt conveyor spray dust falling device provided by the embodiment of the application comprises a cover body 1, a water spraying pipe 2, a communication pipe 3 and a water delivery pipe 4. The cover body 1 comprises a mounting shell 7 and two support blocks 8. The two support blocks 8 are oppositely arranged on a belt conveyor rack 9. The support blocks 8 are provided with accommodating grooves 10 and fixing mechanisms 11. The lower ends of the two sides of the mounting shell 7 are slidably arranged in the accommodating grooves 10. The fixing mechanisms 11 are used for fixing the mounting shell 7. A plurality of water spraying pipes 2 are arranged in parallel on the inner wall of the mounting shell 7. The water spraying pipes 2 are located above the belt conveyor. A plurality of atomizing nozzles 12 are arranged on the water spraying pipes 2. The communication pipe 3 is arranged between the water spraying pipe 2 and the water delivery pipe 4. The end of the communication pipe 3 away from the water spraying pipe 2 is provided with a first quick connector 13. One end of the water delivery pipe 4 is provided with a second quick connector 14. The communication pipe 3 and the water delivery pipe 4 are connected through the first quick connector 13 and the second quick connector 14. The other end of the water delivery pipe 4 is provided with a third quick connector 15. The high-pressure water pipe 6 is provided with a fourth quick connector 16 and a control valve 5. The water delivery pipe 4 and the high-pressure water pipe 6 are connected through the third quick connector 15 and the fourth quick connector 16.

[0030] In use, the mounting shell 7 is first arranged on the support block 8. Then the mounting shell 7 is fixed by using the fixing mechanism 11. After the communication pipe 3 and the water delivery pipe 4 are assembled, the spray dust falling operation can be performed. When the atomizing nozzles 12 in the mounting shell 7 need to be maintained, the communication pipe 3 and the water delivery pipe 4 are first disassembled. Then the fixing of the mounting shell 7 by the fixing mechanism 11 is released. Thus the mounting shell 7 can be taken down as a whole. Therefore, the work efficiency is improved. Thus the atomizing nozzles 12 inside the mounting shell 7 can be conveniently maintained and repaired.

[0031] In the embodiment, the fixing mechanism 11 comprises a bolt 17 and a stop block 18. The bolt 17 is arranged on the support block 8. The bolt 17 is used for fixing the stop block 18 on the support block 8. In use, after the mounting shell 7 is arranged on the support block 8, the stop block 18 is rotated to abut against the end of the mounting shell 7. After the bolt 17 is tightened, the mounting shell 7 can be fixed. After the bolt 17 is loosened, the stop block 18 is rotated. Thus the mounting shell 7 can be conveniently taken down as a whole.

[0032] In the embodiment, the mounting shell 7 and the water spraying pipe 2 are both in an arch-shaped structure. The water spraying pipe 2 in the arch-shaped structure can make the water vapor sprayed by the atomizing nozzles 12 form an arc-shaped water vapor cover. The water vapor cover covers the dust. Thus the dust falling effect is improved.

[0033] In the embodiment, the water delivery pipe 4 is a hose. The hose has the characteristic of being bendable. Thus the convenience of disassembling the communication pipe 3 and the water delivery pipe 4 is improved.

[0034] In the embodiment, the water spraying pipe 2 is fixed on the mounting shell 7 by a pipe clamp 19. The pipe clamp 19 has the advantages of simple design and easy installation.

[0035] In this embodiment, the support block 8 is bolted to the belt conveyor frame 9.

[0036] In this embodiment, the accommodating groove 10 is a convex structure, and the lower end of each side of the installation shell 7 is a T-shaped structure.

[0037] The above only is the preferred embodiment of the present application, and is not used to limit the present application, for the person skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the protection scope of the present application.
