During the rotation, the stirring rods 84 push the surface of the corresponding stirring blades 92, driving the connecting rod 91 to rotate, so as to stir and mix the raw materials in the batching box 1. After a period of time, the bottom plate 12 is pulled out along the inlet 110 to open the discharge square tube 10, so that the mixed raw materials are discharged from the discharge square tube 10. During the discharge process, the rotating spiral blades 85 stir the raw materials in the discharge square tube 10, further accelerating the discharge efficiency of the raw materials and preventing blockage.

[0032] The electric telescopic pole 74, the rotating motor 81, and the controller 13 used are all existing products in terms of their specific types and structures.
