[0024] Specifically, an extension plate is provided on the outer side of the top of the fixing frame 24, and the upper end of the stirring shaft 3 is rotatably connected to the extension plate.

[0025] Specifically, at least two stirring shafts 3 are provided, and more than one stirring shaft 3 can be provided as needed, and the stirring blades connected to each stirring shaft 3 have different shapes and structures, so as to be suitable for stirring different dry strength agents when switching.

[0026] like Figure 1 and Figure 2 In the figure, a hydraulic rod 11 is installed on the upper side of the base 1, and the upper end of the hydraulic rod 11 is connected to a placement plate 12, and the placement plate 12 is slidably connected to the outside of the column 2, the lower end of the adjusting motor 26 is connected to a gear set 27, and the lower side of the gear set 27 is fixedly connected to the rotating plate 21 through a connecting rod 28, the upper side of the rotating plate 21 is connected to a bent rod 25, and the upper end of the bent rod 25 is connected to the outer edge of the rotating disk 23, and the bent rod 25 is located on the outside of the fixed plate 22, the lower end of the fixed frame 24 is fixed to the upper side of the rotating disk 23 through a support rod, and a drive shaft is provided on the inner side of the support rod of the fixed frame 24, and the drive shaft is connected to the stirring shaft 3 through a pulley and a belt.
