[0008] As a further optimization of this utility model, a support plate is fixedly installed on the inner wall of the protective shell above the planetary gears, and a support rod is rotatably connected to the top of each of the three planetary gears. The three support rods are movably connected to the inner wall of the support plate.

[0009] As a further optimization of this utility model, a feed inlet is installed on the side wall of the protective shell.

[0010] As a further optimization of this utility model, a movable frame is installed on both sides of the bottom of the barrel, and a push handle is installed on the side wall of the barrel.

The main stirring rod, the first auxiliary stirring rod, and the second auxiliary stirring rod work together to ensure that the material is fully stirred. At the same time, the cleaning brush connected to the bottom of one of the planetary gears can directly clean the inner wall of the barrel after stirring, without the need for additional cleaning steps, achieving a highly efficient combination of stirring and cleaning, and greatly saving time and labor costs.

[0015] 2. In this utility model, a movable frame is installed at the bottom of the material barrel and a push handle is set on the side wall, which makes it convenient for operators to move the barrel flexibly.

[0024] like Figure 1 , Figure 2 , Figure 3As shown, this utility model includes a base 1, a first housing 2 fixedly installed on the top of the base 1, a lifting device 6 installed on the side wall of the first housing 2, a material bucket 7 placed on the top of the base 1, the material bucket 7 including a bucket body 701, a movable frame 703 installed on both sides of the bottom of the bucket body 701 to facilitate the movement of the material bucket 7, a push handle 702 installed on the side wall of the bucket body 701 to facilitate the operator to push the material bucket 7, an inlet valve 705 and a drain valve 706 respectively installed and connected to the side wall of the bucket body 701, the inlet valve 705 being located above the drain valve 706, used to inject cleaning liquid and discharge sewage during cleaning; a discharge valve 704 is installed and connected to the other side wall of the bucket body 701 for discharging material after stirring.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a second housing 4 is installed on the top of the first housing 2, and a planetary gear stirring assembly 5 is installed on the bottom of the second housing 4. The planetary gear stirring assembly 5 includes a protective shell 501, an internal gear disk 510 is fixedly installed on the inner side wall of the protective shell 501, and a feed inlet 503 is installed on the side wall of the protective shell 501 to facilitate material entry into the barrel 701. A support disk 511 is fixedly installed on the inner side wall of the protective shell 501 above the planetary gears 505. The planetary gear stirring assembly 5 also includes a servo motor 509 fixedly installed on the inner side wall of the second housing 4. The output end of the servo motor 509 is fixedly connected to the top of the sun gear 504. All three planetary gears 505 mesh with the side wall of the sun gear 504, and the side walls of all three planetary gears 505 also mesh with the internal gear disk 510. The inner walls mesh, and the tops of the three planetary gears 505 are rotatably connected to support rods. The three support rods are movably connected to the inner wall of the support plate 511, which plays a role in stabilizing the rotation of the planetary gears 505. The bottoms of two of the planetary gears 505 are respectively fixedly connected to the first set of stirring rods 506 and the second set of stirring rods 507. The bottom of the sun gear 504 is fixedly installed with the main stirring rod 508.
