The top of the rotating shaft 10 is fixedly connected to the bottom of the clamping column 18. The clamping column 18 is clamped with the clamping track in the middle of the clamping plate 19 through the groove on the side. The top of the clamping plate 19 is fixedly connected to the bottom of the cylinder 20. The top of the cylinder 20 is rounded, and the internal height of the cylinder 20 is greater than the length of the clamping column 18.

The main power shaft 15 drives the auxiliary plate 2 and the top cross bar 5 to swing. Since the outer surface of the cross bar 5 is slidably sleeved with a rotating sleeve 3, the vertical shaft 9 is driven by the rotating sleeve 3 to slide on the outer surface of the cross bar 5. While the vertical shaft 9 slides, it slides up and down in the circular hole in the middle of the chassis 6, and at the same time drives the chassis 6 to rotate. The chassis 6 drives the clamping column 18 to rotate through the rotating shaft 10, and the top homogenizing barrel 8 rotates to achieve homogenization. When the homogenization work is completed, the homogenization barrel 8 is lifted up and removed, which is convenient for bagging and cleaning the homogenization barrel 8 to avoid affecting the subsequent homogenization work.
