[0025] As a technical optimization solution of the present invention, by providing the bearing 17, the friction between the stirring shell 3 and the first opening 4 can be reduced, thereby reducing the wear of the stirring shell 3 and the first opening 4, thereby extending the life of the device.

[0026] refer to Figure 1 A protective cover 18 is fixedly connected to the top of the stirring shell 3 and located on the surface of the second motor 13 .

[0027] As a technical optimization solution of the utility model, by setting up the protective cover 18, on the one hand, the second motor 13 can be protected from damage, thereby improving the stability of the device; on the other hand, it can prevent the operator from touching the first conical teeth 11, the second conical teeth 12 or the third conical teeth 14 and causing injuries, thereby playing a role in protecting the operator.
