[0023] like Figure 1 , Figure 3 and Figure 4As shown, the aggregation component includes a second main shaft 14, a hinge 15, a movable plate 16, a second gear 17 and a second belt 18. The front sides of the upper and lower parts of the grinding cylinder 1 are rotatably connected to the left and right second main shafts 14. The inner sides of the left and right parts of the grinding cylinder 1 are connected to the upper and lower movable plates 16 through the hinges 15. The movable plates 16 are located above the adjacent second main shafts 14. The front sides of the second main shafts 14 are connected to the second gears 17.
