Ash removal structure of bag-type dust collector

The dust cleaning structure comprises a shell, a supporting plate and a vertical plate, one side of the outer surface of the vertical plate is connected with a supporting rod in a sliding mode, one end of the supporting rod penetrates through the vertical plate and extends to one side of the outer surface of the shell, one end of the supporting rod is connected with a spring in a sleeved mode, and the other end of the supporting rod is connected with the vertical plate. The upper surface of the supporting plate is movably connected with a supporting ring. Through the arrangement of the shell, the supporting plate and the vertical plate, in the using process, when a filter bag of the bag-type dust collector is full of dust, a motor is started firstly, a cam rotates under the acting force of a cam shaft, a supporting rod moves front and back through the cam, the supporting rod moves front and back to drive a supporting ring, and the supporting ring moves front and back to drive the filter bag; the dust is shake
