[0036] like Figures 1 to 8As shown, the outer surface of the limiting roller 204 is in contact with the transmission belt 3, and an upper hopper is provided at one end of the transmission belt 3. The cross-section of the transmission belt 3 is I-shaped, and the outer surface of the middle part of the inner ring of the transmission belt 3 is in contact with the outer surfaces of the driving roller 209 and the auxiliary roller 224. The two ends of the side frame 1 are fixedly connected with the support column 4, and the other end of the support column 4 is fixedly connected with the guide arc plate 5.
