[0031] By arranging a stirring component 350 on the inner side of the discharge port, the material at the discharge port can be stirred to make the material fully mixed and improve the production quality. At the same time, the stirring component 350 can also loosen the material at the discharge port to avoid the material at the discharge port being compacted and affecting the discharge efficiency, thereby improving the stability and reliability of the work.

It is easy to understand that the bottom of the feed tank 310 is set to a hemispherical structure, and the blade is provided with a bending portion, and the bending portion abuts against the bottom of the feed tank 310, thereby improving the stirring efficiency, ensuring product quality, and improving the stability of the work.
