Coal mine underground anti-deformation dustproof device

The utility model discloses an underground coal mine anti-deformation dustproof device which comprises a fixing frame, dust concentration sensors are installed on the left side and the right side of the fixing frame through bolts, an arc-shaped conveying pipe is movably installed in the center of the top of the fixing frame, and the bottom of an inner cavity of the arc-shaped conveying pipe is communicated with an atomizing nozzle. A stable anti-disengaging assembly is installed on the surface of the arc-shaped conveying pipe and located at the bottom of the fixing frame. According to the utility model, the circumferential driving assembly, the atomizing nozzle and the arc-shaped transmission pipe are matched for use, so that the atomizing nozzle can be driven by the first gear and the second gear under the working driving of the driving motor to rotate circumferentially so as to ensure the spraying uniformity, and further, a good dust suppression and prevention effect is achieved; and through cooperative use
