The upper rotating rod 10, the upper rotating rod 2 11, the middle rotating rod 13, the middle rotating rod 2 14, the lower rotating rod 16 and the lower rotating rod 2 17 are driven to rotate. At this time, the two rotating shafts 12 on the same side will slide opposite to each other on the surface of the connecting plate 19, thereby driving the steel ring 5 and the fixing plate 9 to rise, and then driving the suction hopper 6 to rise, so as to facilitate the smooth discharge of the suction hopper 6. During the whole discharge process, the dustproof cloth 21 is always covered on the surface of the suction hopper 6 to reduce dust.

[0026] To sum up: the suction and discharge overhead crane for avoiding dust, the utility model lowers the dustproof cloth 21 to make the gravity ring 22 fit with the material at the bottom, and then discharges the material through the suction and discharge upper tube 4. As the discharged material is piled up, the suction hopper 6 is driven to slowly rise through the scissors-type lifting mechanism. During the whole discharge process, the dustproof cloth 21 is always covered on the surface of the suction hopper 6, thereby reducing dust.
