[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The stirring mechanism includes a driving gear 2 rotatably connected to the inner bottom wall of the box 11. The bottom of the driving gear 2 passes through the bottom of the box 11 through a connecting rod and is fixedly connected to a stirring rod 21.

When the driving gear 2 rotates, the driven gear 3 also starts to rotate through the meshing connection, and the rotation of the driven gear 3 causes the scraper to rotate accordingly. Due to the fixed connection between the rotating ring 1 34 and the rotating ring 2 35, the scraper 46 scrapes the material on the solid wall as the inner wall of the mixing drum 1 rotates. In this way, through the coordinated work of the scraper 46 and the support rod, the material on the solid wall can be effectively scraped off and mixed into the material of the mixing drum 1.
