[0027] The separation amount adjustment assembly includes an adjustment cone cover 14, a pulling tube 15, a variable speed motor 17, a lower pull rod 18, a guide rod 19, a screw hole block 20 and an inner lead screw 21. The adjustment cone cover 14 is located inside the double-layer cone cover 13, and a matrix of four guide holes 141 is opened on the surface of the adjustment cone cover 14. The guide rod 19 and the corresponding guide holes 141 are in sliding contact with each other, and the two ends of the guide rod 19 are respectively connected to the corresponding parts of the inner wall of the double-layer cone cover 13 and one end of the lower pull rod 18;

[0028] One ends of the four lower pull rods 18 are slidably connected to the four strip holes distributed on the annular surface of the pulling tube 15, the screw hole block 20 is installed in the pulling tube 15, and the top end of the pulling tube 15 is fixedly connected to the inner top wall of the adjusting cone cover 14, the screw hole block 20 and the inner lead screw 21 are threadedly connected to each other, and one end of the inner lead screw 21 is connected to the shaft end of the speed change motor 17.
