Self-cleaning hydrodynamic dust falling device

The utility model discloses a self-cleaning hydrodynamic dust falling device. Including a base, supporting frames are fixedly arranged on the two sides of the top end of the base. Rotating shafts arefixedly arranged at the tops of one sides of the two supporting frames; the two rotating shafts are rotationally connected with the middles of the two sides of the shell correspondingly. A connectingcover is fixedly arranged at one end of the shell; a lifting sliding groove is fixedly formed in the bottom of one side of the connecting cover. The lifting sliding groove is in sliding connection with the lifting sliding block. According to the self-cleaning hydrodynamic dust falling device, the electric hydraulic cylinder arranged at the top end of the fixing plate drives the scrubbing brush arranged on one side of the cleaning plate to clean impurities in gaps of a protective net, the protective net is prevented from being blocked by the impurities, and the dust falling efficiency of the dust falling device is reduc
