Description

Technical Field

[0001] The utility model relates to the technical field of mine mining, in particular to a mine mining spray fan. Background Art

[0002] During the mining process, a large amount of mineral powder and dust will be generated in the mine, which will reduce the air quality in the mine and cause physical effects on the miners. Therefore, spray fans are often installed in the mine to improve the air quality in the mine by spraying water mist to settle the dust.

[0003] When in use, the existing mining spray fans usually need to be placed at the location where dust reduction is required inside the mine. When in use, the spray nozzle can be adjusted to move up and down to perform dust reduction treatment on mines at different heights, so that the dust reduction height of the spray fan is increased. However, because the air supply speed of the fan is limited to a certain range, when the spray nozzle is raised, the height of the mist sent by the spray fan will increase and the delivery length will be reduced. That is, the dust reduction spray that could have been sent to the construction site will fall close to the spray fan after the spray nozzle is raised, and the dust reduction spray cannot be sent to the construction site. The position of the spray fan also needs to be adjusted, and the spray fan is generally fixed when in use to prevent it from being affected by external forces and moving, which affects the dust reduction effect. The movement is more troublesome, which is not conducive to the use of the spray fan. Utility Model Content
