2. The invention provides a siphon blanking port guide chute, which can well support a conveying belt by arranging a sliding bed, and reduce the sinking of the conveying belt between carrier roller groups, thereby avoiding unstable gap between a siphon skirt and the conveying belt;

3. the invention provides a siphon blanking port guide chute, wherein damping devices are arranged at two ends of a shell, so that the air flow speed in the guide chute can be well reduced, dust sedimentation is promoted, and overflow is avoided.

4. The invention provides a siphon blanking port guide chute, which is provided with siphon skirts except two sides, wherein the skirts are made of elastic wear-resistant rubber or composite materials, the corresponding angle can be bent at will according to the groove angle of a conveyor, the gap between the siphon skirts and the adjacent end of the conveyor is adjusted, a plurality of cavities are separated by metal sheets, and when the conveyor runs at a high speed, the air flow speed in the cavities is far greater than the speed around the conveyor outside the siphon skirts, so that the air pressure in the cavities is caused to be smaller than the external pressure of the guide chute, thereby forming negative pressure and avoiding the dust in the guide chute from diffusing to the outside. The size of the negative pressure can be controlled by changing the gap between the siphon skirt and the conveyer belt.
