4. The invention provides a siphon type blanking port guide chute, which is characterized in that siphon skirt edges are arranged on two sides of the guide chute, the skirt edges are made of elastic and wear-resistant rubber or composite materials, the skirt edges can be bent at any angle according to the chute angle of a conveyor and the gap of a conveying belt of the siphon skirt edges can be adjusted, the siphon skirt edges and the adjacent conveying ends are separated into a plurality of cavities by metal sheets, when the conveying belt runs at high speed, the air velocity in the cavities is far higher than the velocity around the conveying belt on the outer side of the siphon skirt edges, the air pressure in the cavities is smaller than the external pressure of the guide chute, and therefore negative pressure is formed, and dust in the guide chute is prevented from diffusing to the outside. The negative pressure can be controlled by changing the gap between the siphon skirt and the conveying belt.
