[0025] In this embodiment, the top end of the rotating shaft roller 9 is rotatably connected to the bottom surface of the feeding box 5, and the bottom end of the rotating shaft roller 9 penetrates to the bottom side of the storage tank body 1, and the two are rotatably connected to facilitate the rotation of the spiral disc 6.
