[0024] The control valve group is connected to one end of the first rotating arm 2 through the first movable rotating shaft 1 below, and the other end of the first rotating arm 2 is connected to one end of the second rotating arm 4 through the second movable rotating shaft 3. The first rotating arm 2 and the second rotating arm 4 are both closed gasification chutes, and the other end of the second rotating arm 4 is connected to the material bulk head 5 at the bottom. The material bulk head 5 is supported on a bearing platform 6, and the bearing platform 6 is placed on a linear guide rail and driven to move by a motor, thereby driving the material bulk head 5 to move. The first rotating arm 2 and the second rotating arm 4 can be freely retracted and extended to adapt to different positions of the material bulk head 5.

[0025] An arc guide rail 10 is arranged above the end of the first rotating arm 2. The first rotating arm 2 is connected to the arc guide rail 10 through a basket screw 11. The first rotating arm 2 can perform circular motion in the arc guide rail 10 with the center of the blanking tube as the center and the length of the first rotating arm 2 as the radius. The basket screw can play the role of suspension support and circular motion guidance.

[0026] The first rotating arm 2 and the second rotating arm 4 are connected to a blower or a gasification blower, and when necessary, the airflow is used to assist the material flow and rotation.
