The outer wall of the spiral main shaft 202 is spirally arranged with spiral leaves. When it is necessary to convey the material at any second discharge port 105, the pneumatic control valve at the corresponding position is opened to make the material inside the conveying body 100 fall. When it is not necessary to convey the material to other stations, all the pneumatic control valves are closed to make the material fall at the first discharge port 104.
