Abstract

The utility model relates to the field of material conveying, in particular to a screw conveyor, which has the characteristics of simple structure, convenient operation and easy maintenance. But is not suitable for transporting high-temperature materials, because when the high-temperature materials are transported, the auger shaft can be expanded and elongated axially or the auger blades can be enlarged radially, so that the auger shaft rotates and is blocked, and even the overload and the shutdown of the motor current can be caused. The utility model provides a hollow air-cooled auger shaft and an auger conveying device. When the air cooling device works, compressed air is introduced into the compressed air inlet device, the compressed air enters the hollow auger shaft and is discharged from the radial air holes on the hollow auger shaft, and when the air enters and is discharged, heat on the auger shaft and the auger blades can be taken away, so that the air cooling effect is achieved, and the auger shaft and the auger blades cannot deform when high-temperature materials are transported.
