Dust suppressant spraying device

The invention provides a dust suppressant spraying device, and belongs to the technical field of mine dust removal. Comprising a first air pipe, one end of the first air pipe is fixedly connected with a second air pipe, the inner surface wall of the first air pipe is fixedly connected with a driving fan, the two sides of the outer surface wall of the first air pipe are fixedly connected with supporting frames, and the ends, away from the first air pipe, of the supporting frames are fixedly connected with rotating discs; the spraying device is arranged, six rotating blocks are mutually spliced, a middle channel of the spraying device is in a closed state, a first air pipe and a second air pipe are vertically arranged, external dust is effectively prevented from entering the first air pipe and the second air pipe, and the situation that dust enters a driving fan in the first air pipe is prevented; and meanwhile, the accumulation of dust on the surfaces of the fan blades of the driving fan can be greatly reduced
