The conveyor discharge port 13 can be arranged on the side surface of the conveying channel wall body, and also can be arranged on the bottom surface of the conveying channel wall body; if the conveyor discharge port is arranged on the side face of the wall body of the conveying channel, the material turning impeller is arranged at the position of the spiral rotating shaft corresponding to the conveyor discharge port, and when the spiral rotating shaft rotates, the material output by the spiral blades is pushed out by the material turning impeller. Because the negative pressure air supplement port 11, the conveyor feed port 12, the conveyor discharge port 13 and the negative pressure air extraction port 14 are not necessarily arranged on a straight line, in the conveying channel of the spiral conveying material lifting machine 2, a material conveying line section between the conveyor feed port 12 and the conveyor discharge port 13 can be regarded as a material conveying line section between the intersection point of the conveyor feed port 12 and the axis of the conveying channel and the intersection point of the conveyor discharge port 13 and the axis of the conveying channel; the air supply channel line segment between the negative pressure air supply port 11 and the negative pressure air exhaust port 14 can be regarded as a material conveying line segment between the intersection point of the negative pressure air supply port 11 and the axis of the conveying channel and the intersection point of the negative pressure air exhaust port 14 and the axis of the conveying channel. In practice, since the negative pressure air supplement port 11, the conveyor feed port 12, the conveyor discharge port 13 and the negative pressure air extraction port 14 have a certain width, in the conveying channel of the screw conveyor elevator 2, the material conveying line segment between the conveyor feed port 12 and the conveyor discharge port 13 strictly belongs to a part of the air supplement channel line segment between the negative pressure air supplement port 11 and the negative pressure air extraction port 14.
