The inner wall of the box body 1 is opened with a groove 11, and the edge of the first partition 2 is arranged inside the groove 11. A plurality of guide holes 22 are evenly opened on the edge of the first partition 2, and a guide column 23 is movably arranged inside the guide hole 22. The two ends of the guide column 23 are respectively fixedly connected to the upper and lower inner walls of the groove 11. The guide column 23 is also sleeved with a first spring 24, one end of the first spring 24 is fixedly connected to the inner top wall of the groove 11, and the other end of the first spring 24 is fixedly connected to the top of the first partition 2.

[0044] Further, in order to prevent the material from accumulating and blocking inside the material guiding hole 22, a first bevel gear 424 is fixedly sleeved at the lower edge of the first partition plate 2 on the position of the rotating shaft 42. Second bevel gears 425 are symmetrically meshed on both sides of the first bevel gear 424. A rotating rod 426 is fixedly connected to the center of the second bevel gear 425.
