The utility model adopts a driving gear and a mixing barrel. In actual use, the rotation of the driving motor will drive the driving gear and the stirring paddle to rotate. Since the meshing setting of the driving gear will drive the mixing barrel and the stirring paddle to rotate in a certain direction, the vortex generated by the rotation of the spoiler inside the mixing barrel collides with the vortex generated by the rotation of the stirring paddle, which intensifies the collision interaction effect between the internal substances, thereby improving the overall regeneration mixing effect, and has the advantage of excellent regeneration and recycling performance.
