To achieve a stable effect, a support plate 8 is fixedly connected to the lower end of the feed hopper 2, and the support plate 8 is rotatably connected to the outer wall of the first rotating rod 5. When the first rotating rod 5 rotates, the support plate 8 can be used in conjunction with it and can also support the lower end of the first rotating rod 5.
