By arranging multiple second stirring shafts 402 on the first stirring shaft 301, the multiple second stirring shafts 402 can stir the material in a larger area, preventing some of the material from being stationary in the containing cavity 101 and causing the material to harden. At the same time, by arranging multiple second stirring shafts 402 on the first stirring shaft 301, when the multiple second stirring shafts 402 stir the material, the material simultaneously applies a reaction force to the multiple second stirring shafts 402, so that the force borne by the multiple second stirring shafts 402 is transmitted to the first stirring shaft 301, thereby improving the driving force of the first stirring shaft 301 rotating on the annular track 2, which can improve the stirring efficiency of the first stirring shaft 301.

[0056] The working principle of the discharge device in this embodiment is described as follows:

[0057] The annular track 2 is horizontally fixed on the inner wall of the shell 1, the roller ball 3011 at the two ends of the first stirring shaft 301 is arranged on the annular track 2, so that the first stirring shaft 301 can rotate along the annular track 2, that is, the first stirring shaft 301 can rotate in the horizontal plane. The second stirring shaft 402 is arranged on the first stirring shaft 301, the second stirring shaft 402 is arranged vertically to the first stirring shaft 301, and two second stirring shafts 402 are arranged on the first stirring shaft 301 at intervals. In the process of discharging, the driving member 401 on the second stirring mechanism 4 is started, so that the second stirring shaft 402 rotates to stir the material. At the same time that the second stirring shaft 402 stirs the material, the driving force of the second stirring shaft 402 stirring the material can drive the first stirring shaft 301 to rotate on the annular track 2, so that the first stirring blade on the first stirring shaft 301 also stirs the material. The first stirring shaft 301 and the second stirring shaft 402 are perpendicular to each other, the first stirring shaft 301 and the second stirring shaft 402 respectively stir the material in two different directions during stirring, which can prevent the material at the discharge port 102 from being hardened or blocked, and ensure smooth discharge of the discharge port 102.
