[0035] In this embodiment, the snap-fit ​​frame 7 includes a snap-fit ​​groove 701, a strap 702 and an outer protective shell 703. The outer protective shell 703 is welded to the outer side of the snap-fit ​​frame 7. The rotating motor 602 is fixedly connected to the inner part of the outer protective shell 703. The snap-fit ​​groove 701 is clamped on one side of the snap-fit ​​frame 7. The strap 702 is located on one side of the snap-fit ​​groove 701. The strap 702 is rotatably connected to the snap-fit ​​frame 7 through an axle rod. The strap 702 and the snap-fit ​​frame 7 are fixedly connected by bolts.

[0036] When in use, the tool removes the bolts at the bottom of the clamping frame 7, rotates the strap 702 to open the clamping groove 701, moves the clamping frame 7 away from the steel pipe 8, and removes the entire spray device from the top of the coal yard shed, making it easier to repair and replace the spray device.

A rubber water pipe 2 is provided at the bottom of the positioning frame 9, and one end of the rubber water pipe 2 is connected to the positioning ring 902. A control valve 201 is fixedly installed on the side of the rubber water pipe 2 away from the positioning ring 902, and a water receiving box 10 is provided on the other side of the positioning ring 902.

[0040] When in use, when the atomizing ring tube swings, the rubber water tube 2 is driven to stretch in the positioning ring 902 of the positioning frame 9, so that the relatively loose rubber water tube 2 is straightened to move with the atomizing ring tube. The rubber water tube 2 has good elasticity and a soft body, which is not only convenient for water flow transportation, but also conducive to the swing of the atomizing ring tube.

[0041] In this embodiment, the water receiving box 10 is located at the bottom of the outer shell 5, and an atomizing ring tube 1 is provided inside the water receiving box 10.

[0042] When in use, the staff manually closes the control valve 201 on the rubber water pipe 2 to stop the water transport of the rubber water pipe 2. At the same time, the water flow inside the atomizing ring tube flows into the water receiving box 10 through the nozzle 102 to prevent water dripping from affecting the staff's disassembly of the spray device. The rubber water pipe 2 is rotated to separate the water inlet 104 and the water outlet 105 of the atomizing ring tube.

[0043] In this embodiment, the ear rack 1004 is located at the top of the slide groove 1002 and the docking groove 1001, and a stretching rod 1003 is fixedly connected to the bottom of one end of the ear rack 1004.

One end of the atomizing ring tube 1 and the half hoop frame 502 are both docked inside the docking groove 1001.

[0044] During use, when the spray device needs to be replaced, the staff stretches the ear rack 1004, so that the stretching rod 1003 pushes the stretching ear rack to rise in the slide groove 1002, and hangs the extended stretching ear rack on the top of the limiting frame 501, so that the atomizing ring tube is engaged with the inside of the water receiving box 10.

[0045] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: when the dust content in the coal yard air is high, the staff starts the atomizing ring tube and the driving motor 4, the water flow is transported to the atomizing ring tube through the rubber water pipe 2, and the water flow is atomized and sprayed out through the nozzle 102. At the same time, the driving motor 4 drives the mist fan 3 to rotate rapidly in the shell 5, and the wind driven by the mist fan 3 blows the sprayed water mist, so that the water mist quickly diffuses in the air, and the water mist combines with the dust to make the dust fall quickly. , to purify the air in the coal yard. In order to expand the range of water mist dispersal, the staff starts the rotating motor 602, and the rotating motor 602 drives the shaft column 601 to rotate, so that the chassis 6, the shell 5 and the atomizing ring tube follow the shaft column 601 to rotate in the clamping frame 7, so that the atomizing ring tube swings to spray water mist. When the atomizing ring tube swings, it drives the rubber water pipe 2 to stretch in the positioning ring 902 of the positioning frame 9, so that the relatively loose rubber water pipe 2 is straightened and moves with the atomizing ring tube. The rubber water pipe 2 has good elasticity and is relatively soft. , which is not only convenient for water flow transportation, but also conducive to the swing of the atomizing ring tube. The rubber water pipe 2 is connected to the positioning ring 902 through the rubber water pipe 2 to position and receive it. When the spray device needs to be replaced, the staff stretches the ear rack 1004, so that the stretching rod 1003 pushes the stretching ear rack to rise in the slide 1002, and hangs the extended stretching ear rack on the top of the limit rack 501, so that the atomizing ring tube is clamped in the water receiving box 10. The staff manually closes the control valve 201 on the rubber water pipe 2 to make the rubber water pipe 2 Pipe 2 stops water transport, and at the same time, the water flow inside the atomizing ring pipe flows into the water receiving box 10 through the nozzle 102 to prevent water dripping from affecting the staff's disassembly of the spray device. The rubber water pipe 2 is rotated to separate the water inlet 104 and the water outlet 105 of the atomizing ring pipe, and then the bolts at the bottom of the clamping frame 7 are removed with tools, the strap 702 is rotated to open the clamping groove 701, and the clamping frame 7 is moved away from the steel pipe 8, so that the spray device can be disassembled from the top of the coal yard shed as a whole, which is convenient for the maintenance and replacement of the spray device.
