[0031] The technical solution provided by this embodiment is as follows: when in use, the bevel gear 2 11 is driven to rotate by the motor 12, and the bevel gear 10 meshing therewith is driven by the motor 11, so that the rotating rod 8 drives the spiral blade 9 to rotate, and the raw materials in the barrel 3 are discharged through the discharge pipe 21, and are transported to the feeding pipe 4 through the feeding mechanism and enter the distribution box 5, so that the raw materials can flow to the discharge port 7 under the action of the guide block 6.
