After the auxiliary frame 23 is placed, it is arranged in a vertical state, wherein the inner ring frame is connected to the first cylinder cover 7 in a movable through-type manner, and the lower end frame is fixedly connected to the frame body of the bottom frame 1 by bolts. Moreover, since the left and right plate walls of the shift plate 17 are vertically provided with an integrated structure of the shaft column frame, between the two adjacent dispersing mechanisms 13, the shaft bodies of the shaft column frames in the two adjacent shift plate members 17 are connected by a linkage shaft, and the groove gear 22 is fixedly connected to the linkage shaft of the leftmost dispersing mechanism 13 by bolts.
