The invention relates to a novel air conveying chute, and belongs to the technical field of powder material conveying devices. The air conveying chute comprises an upper box, a lower box, a fiber ventilation layer, an airflow control plate and a screen; the upper box and the lower box are buckled to form a conveying channel; the fiber ventilation layer, the airflow control plate and the screen divide the conveying channel into a feeding chamber on the upper side and an air blowing chamber on the lower side; the airflow control plate comprises a substrate, and multiple strip-shaped projectionsarranged on the substrate; the cross sections of the projections are of isosceles trapezoid structures; cavities are formed in the projections; and multiple through holes penetrating through the sidewalls and the tops of the projections are formed in the upper half parts of the projections. Compared with the prior art, the airflow control plate is arranged in the air conveying chute for improvingthe air blowing uniformity so as to improve the powder material conveying efficiency.
