[0032] According to some embodiments of the present invention, referring to Figures 1 to 4 The mixing agitator includes a mixing tank 100 and a stirring device 130. A feeding bin 110 is provided on the top of the mixing tank 100, and the feeding bin 110 is connected to the inner cavity of the mixing tank 100. A discharge pipe 120 is connected to the bottom of the mixing tank 100. The stirring device 130 includes a blade assembly 200, a drive shaft 140 and a driving component 150. The driving component 150 is installed on the mixing tank 100, the blade assembly 200 is arranged in the inner cavity of the mixing tank 100, the drive shaft 140 is coaxially arranged with the mixing tank 100, and the driving component 150 can drive the drive shaft 140 to rotate. The blade assembly 200 includes a plurality of stirring blades 210 arranged in the up-down direction, one side of the stirring blade 210 located at the top is connected to the drive shaft 140, and two stirring blades 210 adjacent to each other are detachably connected.

[0033] Reference Figure 2 and Figure 3 Among the two adjacent stirring blades 210, the spacing between the side of the stirring blade 210 located above and away from the axis of the mixing tank 100 and the inner wall of the mixing tank 100 is a first spacing, and the length of the first spacing is A. The spacing between the side of the stirring blade 210 located below and away from the axis of the mixing tank 100 and the inner wall of the mixing tank 100 is a second spacing, and the length of the second spacing is B. The first spacing is smaller than the second spacing, and A is smaller than B.

[0034] It is understandable that when the driving component 150 drives the driving shaft 140 to rotate, the driving shaft 140 drives the blade assembly 200 to rotate synchronously. Since the first spacing is smaller than the second spacing, when the stirring blade 210 stirs the material, the material moves relative to the stirring blade 210, and the rate at which the material located below passes through the stirring blade 210 and the inner wall of the mixing tank 100 is higher than the rate at which the material located above passes through the stirring blade 210 and the inner wall of the mixing tank 100. In the process of the stirring blade 210 rotating to push the material, the material located above the area where the stirring blade 210 passes can be gradually replenished downward under the action of gravity, thereby improving the mixing uniformity of the material.

[0040] Preferably, refer to Figure 2 The area between the lower end of the lowest stirring blade 210 and the bottom of the mixing tank 100 is the discharge area 240, and the discharge pipe 120 is connected to the discharge area 240. After the material enters the discharge area 240, the discharge pipe 120 can be connected to the extraction device to quickly extract the material located in the discharge area 240.

[0041] Preferably, refer to Figure 1The feeding bin 110 is rotatably connected to a cover plate 250 , and the cover plate 250 is used to block the feeding port 111 of the feeding bin 110 to prevent foreign matter from entering the mixing tank 100 .

[0042] Preferably, refer to Figure 2 The driving component 150 is located above the mixing tank 100, the driving end of the driving component 150 faces downward, the driving shaft 140 is passed through the top cover 260 of the mixing tank 100, and the driving shaft 140 and the driving end of the driving component 150 are fixedly connected through the coupling 160.
