Description

Technical Field

[0001] The utility model belongs to the technical field of mine dust suppression equipment, and particularly relates to a mine wind and water mist cannon dust suppressor. Background Art

[0002] Coal mining is accompanied by a large amount of dust, and dust concentration is a parameter that must be strictly controlled in mines. Coal mining generates large amounts of coal dust during excavation, loading, transportation, and unloading. This dust not only affects workers' health and reduces their visibility, but also can cause explosions when dust concentration reaches critical levels. Therefore, dust suppression equipment is an essential piece of equipment in mines. Current dust suppression devices generally use suspended, fixed-mounted atomizing nozzles triggered by wireless sensors to achieve dust suppression. However, this structure is immobile and can only spray over a large area from top to bottom. In addition, there are also some dust suppression water cannons on the market, but they are also difficult to carry and are not suitable for mine environments.

[0003] In the existing technology, such as the "multi-angle water mist dust suppression device" provided by China Utility Model Patent Authorization Announcement No. CN218392873U, it includes a wind cannon, a rotating shaft is provided in the middle position of the front and rear surfaces of the side wall of the wind cannon, a support frame is provided on the outside of the wind cannon at a position corresponding to the rotating shaft, a support rod is provided at the middle position of the lower end of the support frame, a fixed plate is provided at the lower end of the support rod, an adjustment shaft is provided on the front and rear surfaces of the side wall of the wind cannon and to the right of the rotating shaft, an adjustment frame is provided on the outside of the wind cannon at a position corresponding to the adjusting shaft, a connecting seat is provided in the middle position of the support rod, one side of the connecting seat is connected to the adjusting rod by rotating through the rotating shaft, a pull rod is provided between the adjusting rod and the adjusting frame, and the other side of the connecting seat is connected to one end of a damping telescopic rod by rotating through the rotating shaft. Although the above technical solution uses a water cannon to adjust the dust reduction at multiple angles, the device itself needs to be matched with a carrier, and the wind cannon, as the main component of the spray dust reduction, has not been disclosed in terms of structure, and the dust reduction effect cannot be expected.

[0004] In view of the above situation, it is necessary to design a mine-used wind and water mist cannon dust suppressor with simple structure, low cost, and good dust reduction effect that can be placed at any position. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Utility Model Content
