[0007] Specifically, the linkage mechanism includes an internal gear ring, a first gear, a second gear, and a spline sleeve. The internal gear ring is rotatably connected to the inner wall of the mounting box. The first gear is fixedly connected to the outer wall of the first stirring shaft. The second gear is fixedly connected to the outer wall of the spline sleeve. The first and second gears are located inside the mounting box. The second gear meshes with the first gear and the internal gear ring, respectively. The spline sleeve is rotatably connected to the inner wall of the mounting box. The top of the second stirring shaft passes through the spline sleeve and the mounting box and is rotatably connected to a connecting plate. The top of the second stirring shaft is provided with spline teeth that match the spline sleeve. The part of the first stirring shaft located between the mounting box and the protective cover is provided with external threads, and a lifting plate is threadedly connected to the outer wall.

[0008] Specifically, the top of the mounting box is equipped with a sleeve that is fixed to the protective cover, and the connecting plate is slidably connected to the sleeve on the side away from the lifting plate.
[0009] Specifically, the outer wall of the second stirring shaft is fitted with a corrugated expansion tube, and the top of the corrugated expansion tube is rotatably connected to the bottom of the mounting box, while the bottom is rotatably connected to the outer wall of the second stirring shaft. The spline teeth below the mounting box are located inside the corrugated expansion tube.
[0010] The beneficial effects of this invention are as follows: Through the synergistic action of the first stirring shaft and multiple second stirring shafts, the staggered arrangement of the first, second, and third stirring blades, and the up-and-down floating function of the third stirring blade, this invention can effectively reduce dead zones in the stirring process, improve the uniformity of stirring, and is particularly suitable for materials with high viscosity or easy sedimentation. By driving the first stirring shaft to rotate forward and backward with a motor and under the action of the linkage mechanism, the second stirring shaft can be rotated and moved up and down, thereby achieving flexible stirring control. This invention ensures thorough stirring during liquid preparation, resulting in good mixing effect and high-quality liquid preparation. Attached Figure Description

The top of the first stirring shaft 6 passes through the mounting box 2 and the protective cover 3 and is fixedly connected to the main shaft of the motor 7. A U-shaped scraper 8 that contacts the inner wall of the tank body 1 is fixedly connected to the bottom of the first stirring shaft 6. A slider 14 is provided on the top of the scraper 8. A groove corresponding to the slider 14 is provided on the top of the tank body 1. The slider 14 is slidably disposed in the groove. A number of first stirring blades 9 are provided from top to bottom on the outer wall of the first stirring shaft 6. A number of second stirring blades 10 corresponding to the first stirring blades 9 are provided on the side of the scraper 8 facing the first stirring shaft 6.
[0021] The mounting box 2 contains several second stirring shafts 11 evenly distributed around the circumference of the first stirring shaft 6. A linkage mechanism connects the first stirring shaft 6 and the second stirring shafts 11. The second stirring shafts 11 rotate and reciprocate within the mounting box 2 via the linkage mechanism. The outer wall of each second stirring shaft 11 has several third stirring blades 12 that are staggered with the first stirring blades 9. The linkage mechanism includes an internal gear ring 15, a first gear 16, a second gear 17, and a splined sleeve 18. The internal gear ring 15 is rotatably connected to the inner wall of the mounting box 2. The first gear 16 is fitted and fixed to the outer wall of the first stirring shaft 6, and the second gear 17 is fitted and fixed to the outer wall of the splined sleeve 18. Gear 17 is located inside the mounting box 2. The second gear 17 meshes with the first gear 16 and the internal gear ring 15 respectively. Spline sleeve 18 is rotatably connected to the inner wall of the mounting box 2. The top of the second stirring shaft 11 passes through the spline sleeve 18 and the mounting box 2 and is rotatably connected to the connecting plate 19.
