Novel dust -falling spraying device

The invention relates to the technical field of dust-falling spraying devices and discloses a novel dust-falling spraying device which comprises a transverse plate, a transverse moving plate is arranged above the transverse plate, vertical plates are fixedly installed on the two sides of the top face of the transverse plate, the top faces of the vertical plates are fixedly installed in an air return roadway, a first through hole is formed in the top face of the moving plate, and a spherical groove is formed in the top face of the transverse plate. A ball is arranged in the spherical groove, a second through hole is formed in the top of the ball, a vertical pipe is arranged in the second through hole and connected with the second through hole through a bearing, and a hollow plate is fixedly installed at the lower end of the vertical pipe and communicated with the interior of the vertical pipe. The device is reasonable in structural design, convenient to use, capable of effectively conducting spraying and dust
