The guide chute body (3) is arranged on a conveyer (2), the discharging port (1) is communicated with the first end of the guide chute body (3), the guide curtains (6) are arranged in the guide chute body (3), the air stop curtains (5) are arranged at the second end of the guide chute body (3), the dust removal air pipe connector (4) is connected to one or two sides of the guide chute body (3), and the flow direction of the dust removal air pipe connector (4) is basically the same as the flow direction, changed by the guide curtains (6), of induced air. The guide chute can reduce overflow of the induced air, improve air draft efficiency and reduce raised dust.
