[0033] In this embodiment, in order to achieve the effect of continuously dispersing the incoming material in a circle, a feed dispersion component 4 is designed. A rotating seat 4-3 is rotatably connected to the top of the shell 3, and an external gear 4-4 is provided. A fixing frame 4-1 and a driving motor 4-2 are fixedly connected to the top of the shell 3. A driving gear 4-5 is provided at the output end of the driving motor 4-2. The driving gear 4-5 is meshed with the external gear 4-4 to drive the rotating seat 4-3 to rotate. A docking nozzle 4-6 is provided on the top of the rotating seat 4-3. The shell 3 A feed pipe 4-7 is fixedly connected to the top, and the feed pipe 4-7 is connected to the docking nozzle 4-6 in a sealing and rotating sleeve. An inner pipe 4-8 is arranged at the bottom of the rotating seat 4-3. Two round rods 4-9 are fixed to the outer wall of the inner pipe 4-8. A dispersion pipe 4-10 with multiple dispersion holes 4-11 is fixed at one end of the round rod 4-9. The material can be sprayed into the interior through the feed pipe 4-7, the docking nozzle 4-6, the inner pipe 4-8, the dispersion pipe 4-10 and the dispersion holes 4-11, and can be evenly covered by rotating.

[0034] Furthermore, the docking processing assembly 5 includes a pair of telescopic cylinders 5-1, and the telescopic cylinders 5-1 are respectively installed at the opposite ends of the bottom of the outer shell 3. The output end of the telescopic cylinder 5-1 is provided with a bracket 5-2, and the bracket 5-2 is plugged into and connected to a bottom cover 5-3, and the bottom cover 5-3 is attached to the bottom of the outer shell 3.
