One side of the scraper 15 contacts the inner wall of the batching tank 1. While the material inside the batching tank 1 is mixed by the agitator assembly 2, the vertical plate 14 is driven to remove the material at the edge. After the mixed material is discharged, the vertical plate 14 drives the scraper 15 to scrape off the material adhered to the inner wall of the batching tank 1, that is, the vertical plate 14 serves two purposes. This further solves the problem that the residual material on the inner wall of the existing mixing device is inconvenient to clean. The residual material adhered to the inner wall can be scraped off after the mixing is completed.

[0025] Embodiment 2

[0026] Refer to the attached Figure 4 and Figure 5As shown in the figure, on the basis of the first embodiment, in order to drive the transmission gear 7 to drive the turntable 9 to rotate while the rotating shaft of the stirrer assembly 2 rotates, a limiting shaft 8 is inserted into the inner ring surface of the transmission gear 7. The limiting shaft 8 has an inverted "T"-shaped cylindrical structure. The top end of the limiting shaft 8 is fixed to the bottom surface of the top plate of the batching tank 1. The bottom diameter of the limiting shaft 8 is larger than the inner ring diameter of the transmission gear 7. There are two transmission gears 7, and the two transmission gears 7 are symmetrically distributed with respect to the driving gear 6. A bearing is sleeved on the rod body of the limiting shaft 8, and the outer ring of the bearing is fixed in the inner ring opening of the transmission gear 7; a plurality of first teeth 10 are fixed on the inner ring surface of the turntable 9, and the first teeth 10 mesh with the second teeth provided on the surface of the transmission gear 7; the density of the third teeth provided on the surface of the driving gear 6 is greater than the density of the first teeth 10; a hanging groove 11 is formed on the top surface of the turntable 9. The hanging groove 11 is an annular groove with a "convex"-shaped break. A hanging plate 12 is rotatably connected inside the hanging groove 11. The hanging plate 12 is a circular ring plate with a "convex"-shaped cross section, and the top surface of the hanging plate 12 is fixed to the bottom surface of the top plate of the batching tank 1.

[0027] After triggering the switch of the stirrer assembly 2, the stirrer assembly 2 stirs the materials input into the batching tank 1 from the feeding port 3. During this process, the driving gear 6 rotates synchronously with the rotating shaft of the stirrer assembly 2, and the driving gear 6 meshes with the transmission gear 7 and drives the transmission gear 7 to rotate around the limiting shaft 8 as the central axis. When the transmission gear 7 rotates, it meshes with a plurality of first teeth 10 provided on the inner ring surface of the turntable 9. Therefore, the turntable 9 rotates. During the process of the materials being stirred by the stirrer assembly 2, the turntable 9 drives the vertical plate 14 to push the materials close to the inner wall of the batching tank 1 forward.

[0028] Embodiment Three

[0029] Refer to the attached Figure 6 As shown in the figure, on the basis of the second embodiment, in order to drive the scraper 15 to scrape off the residual materials on the inner wall of the batching tank 1 while the turntable 9 is driving, the vertical plate 14 has a "C"-shaped plate-like structure. A connecting plate 13 is fixed on the top surface of the vertical plate 14. A plurality of screws are provided on the surface of the connecting plate 13 to fix the connecting plate 13 to the bottom surface of the turntable 9; an isosceles trapezoidal plate is integrally formed on one side of the scraper 15 for scraping off the residual materials on the inner wall of the batching tank 1.

[0030] When the materials inside the batching tank 1 are mixed by the stirrer assembly 2 and finished, the mixed materials are discharged through the discharge valve pipe 5. At this time, trigger the switch of the stirrer assembly 2. During the rotation of the stirrer assembly 2, the turntable 9 is driven to rotate. Since the density of the third teeth of the driving gear 6 is greater than the density of the first teeth 10 on the inner ring surface of the turntable 9, the rotation speed of the turntable 9 is less than the rotation speed of the driving gear 6. During the rotation of the turntable 9, at this time, the vertical plate 14 no longer feeds the materials, but drives the scraper 15 to scrape off the residual materials on the inner wall of the batching tank 1.

[0031] In actual use, after the switch of the agitator assembly 2 is triggered, the agitator assembly 2 stirs the material put into the batching tank 1 from the feeding port 3. In this process, the driving gear 6 rotates synchronously with the rotating shaft of the agitator assembly 2, and the driving gear 6 is meshed with the transmission gear 7, and drives the transmission gear 7 to rotate with the limit shaft 8 as the central axis. When the transmission gear 7 rotates, it meshes with a plurality of teeth 10 set on the inner ring surface of the turntable 9, so that the turntable 9 rotates. In the process of the material being stirred by the agitator assembly 2, the turntable 9 drives the vertical plate 14 to move toward the inner ring surface of the batching tank 1. The material on the wall is pushed forward; when the material inside the batching tank 1 is mixed by the agitator component 2, the mixed material is discharged through the discharge valve pipe 5, and the switch of the agitator component 2 is triggered. The agitator component 2 drives the turntable 9 to rotate during its rotation. Since the density of the tooth three of the driving gear 6 is greater than the density of the tooth one 10 on the inner ring surface of the turntable 9, the rotation speed of the turntable 9 is lower than the rotation speed of the driving gear 6. During the rotation of the turntable 9, the vertical plate 14 no longer pushes the material, but drives the scraper 15 to scrape off the residual material on the inner wall of the batching tank 1.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
