When the centrifugal force is greater than the elastic force of the elastic member, the sliding block gradually moves away from the stirring shaft. Under the transmission of the connecting rod one, the connecting rod two gradually changes from an inclined state to a vertical state. In cooperation with the stirring blades on the connecting rod two, the stirring speed can be accelerated without long-term operation of the driving mechanism at a high speed.
[0006] Further, a sliding groove is arranged on the cross shaft and the sliding block is slidingly connected in the sliding groove. The elastic member is arranged between the end of the sliding block and the corresponding groove wall. The butt joint structure of the sliding block and the sliding groove on the cross shaft facilitates assembly.
[0007] Further, the end of the cross shaft is hinged to the connecting rod two and the connecting rod two is hinged to the corresponding sliding block on the cross shaft, which helps to further improve the mixing speed of the material.
[0008] Further, the utility model also includes a kettle body. The driving mechanism is arranged at the top of the kettle body. The output end of the driving mechanism is connected to the stirring shaft. The stirring shaft and the cross shaft are located in the cavity of the kettle body.
[0009] Further, an inlet pipe is arranged on the side wall of the kettle body and an outlet pipe is arranged on the bottom wall, which facilitates feeding and discharging.
