Suction nozzle electric rising and falling type charging basket dust conveying device

The invention relates to a suction nozzle electric rising and falling type charging basket dust conveying device, which comprises a rack, an electric winch, fixed pulleys, a guide rod, a centering roller, an upper linear bearing, a lower linear bearing, a lower limiting switch, a suction nozzle, an upper limiting block, an upper limiting switch, a lower limiting block, a lifting ring, a conveyinghose, an upper cross beam and a lower cross beam, wherein the cross beam is fixed on the rack; one end of the guide rod is guided by a linear bearing fixed on the cross beam, the other end of the guide rod leans against the centering roller and is connected with the outer side of the barrel of the suction nozzle through screws; the electric winch is mounted on the inner side of the rack; a steel wire rope of the winch penetrates through the pair of fixed pulleys to be connected to a lifting ring fixed to the guide rod; the winch is driven by a servo motor to rotate to wind and unwind the steelwire rope; the suction nozzle is made to rise and fall under the guide of the guide rod, returning to replace the charging basket is conducted in the rising case, suction and conveying of the dust are conducted in the falling case, and therefore, conveying of the dust in the charging basket is automatically completed. By means of the device, the pneumatic conveying efficiency of dust in the charging basket is improved, the labor intensity of operators is relieved, and secondary pollution to the environment is avoided.
