Technical Field

[0001] This utility model relates to the field of electromechanical technology in coal mines, and specifically to a multifunctional spraying device. Background Technology

[0002] Coal mining has always been an important supporting industry for the country's energy extraction. During the production process, various work sites in coal mines generate a large amount of dust. The unique properties of coal dust determine that it is very harmful: it can induce occupational diseases such as pneumoconiosis; accelerate the wear and tear of mechanical equipment and shorten the service life of precision instruments; and even lead to coal dust explosion accidents.

[0003] In the existing technology, most equipment for spray dust suppression in coal mines uses a spray pipe that is fixedly installed inside the spray cylinder. The spray pipe sprays water mist to suppress dust. However, in the existing technology, the spray direction of the spray pipe is fixed, which makes it difficult to adapt to different dust suppression needs and is inconvenient for users.

A support and adjustment mechanism 2 is provided on the top surface of the trolley 1, and a spraying mechanism 3 is provided at the top of the support and adjustment mechanism 2. The spraying mechanism 3 includes a spray cylinder 301, one end of which is closed and the other end is open. A motor frame 302 is fixedly connected inside the open end of the spray cylinder 301. A spray pipe 303 is rotatably connected to the inner circumferential array of the open end of the spray cylinder 301. An air inlet is provided at the closed end of the spray cylinder 301. A motor 304 is fixedly connected to the side of the motor frame 302, and a lead screw 305 is fixedly connected to the output shaft of the motor 304. A threaded block 306 is threaded to the surface. A sliding groove is fixedly connected to the outer surface of the threaded block 306 in a circumferential array. A connecting post is fixedly connected to one side of the spray pipe 303. The connecting post is located inside the sliding groove. A support frame 307 is fixedly connected to the open end of the spray cylinder 301. One end of the lead screw 305 is rotatably connected to the inside of the support frame 307. A filter screen groove 308 is fixedly connected to the outer surface of the closed end of the spray cylinder 301. The filter screen groove 308 is interconnected with the inside of the spray cylinder 301. A filter screen 309 is slidably connected inside the filter screen groove 308. An exhaust fan 310 is fixedly connected inside the spray cylinder 301. The exhaust fan 310 is located between the motor frame 302 and the filter screen groove 308.

[0033] In this embodiment, when performing dust removal work, the trolley 1 is pushed to move the entire spray device to the designated position, and the spray pipe 303 and exhaust fan 310 are started. The spray pipe 303 sprays water mist to reduce dust. When the exhaust fan 310 is working, external air enters the spray cylinder 301 through the air inlet on the closed end of the spray cylinder 301. The spray cylinder 301 is connected to the filter screen 309 through the filter screen groove 308. The filter screen 309 filters the air to prevent dust in the air from accumulating in the spray cylinder 301 and affecting the operation of the internal components of the spray cylinder 301. The filtered air is discharged through the open end of the spray cylinder 301. The discharged air helps to increase the diffusion area of ​​the water mist, thereby increasing the dust reduction range.

[0034] During dust removal, the user can start the motor 304 to drive the lead screw 305 to rotate according to the dust removal requirements. The support frame 307 is connected to the lead screw 305 to support one end of the lead screw 305, thereby improving the rotational stability of the lead screw 305. When the lead screw 305 rotates, it drives the threaded block 306 to move. The threaded block 306 drives multiple spray pipes 303 to rotate through multiple sliding grooves and connecting columns, thereby adjusting the spraying direction of the spray pipes 303. The rotation of multiple spray pipes 303 can make the sprayed water mist more diffused, making it easier for the user to adjust the spray range according to the dust removal requirements.

After the filling is completed, the sealing cap is connected to the water inlet pipe 103 to seal the water inlet pipe 103.

[0041] When performing dust removal work, push the trolley 1 to the designated position, start the water pump 102, the water pump 102 draws water out of the water tank 101, and inputs the water into multiple spray pipes 303 through hoses, diverter connectors and diverter pipes, and the spray pipes 303 spray water mist to perform dust removal work.

[0042] The trolley 1 is connected to the battery 106 through the protection box 105. The protection box 105 stores and protects the battery 106.
