The screw elevator can be divided into vertical ascending type and inclined ascending type according to the lifting direction. The vertical ascending type screw elevator generally comprises a support, a feeding port, a cylinder, a screw blade driven by a speed reducer, and a discharging port. When working, the screw blade rotates under the driving of the speed reducer to generate upward power to force the material to rotate and ascend to realize conveying.
