The top of the mixing drum 13 is threadedly connected to a top frame 7, and a drive motor 32 is installed at the top of the top frame 7. The rotating shaft of the drive motor 32 is connected to the connector 25. In use, the mixing drum 13 facilitates the placement of materials, and its sieve plate 31 can effectively support the materials. Starting the drive motor 32 can drive the stirring rod 22 to rotate, and the stirring rod 22 can drive the scraper 27 to rotate. The scraper 24 can continuously push the materials at the top of the sieve plate 31, thereby dispersing the materials so that they can fall into the mixing drum 13 through the sieve plate 31, thereby improving the uniformity of material mixing. During the rotation of the stirring rod 22, its support rod 23 will also drive the scraper 27 to rotate together. The scraper 27 can scrape off the materials adhering to the inner wall of the mixing drum 13, which is convenient and practical.

[0026] refer to Figures 1 to 4The inner wall of the mixing tank 13 is provided with a first groove 28 that matches the scraper 27. The scraper 27 is slidably connected to the inner wall of the mixing tank 13 through the first groove 28. A second groove 29 is provided on the other side of the scraper 27. A slider 26 that matches the second groove 29 is fixedly connected to one side of the support rod 23. The slider 26 is slidably connected to the inner side of the second groove 29. Due to the opening of the first groove 28, the sliding point of the scraper 27 can be effectively pulled, which can improve the stability of the sliding point of the scraper 27. Due to the opening of the second groove 29, it is convenient for the user to disassemble the support rod 23 and the scraper 27.

[0027] refer to Figures 1 to 4 The inner wall of the mixing barrel 13 is provided with a third sliding groove 30 that matches the sieve plate 31. The sieve plate 31 is slidably connected to the inner wall of the mixing barrel 13 through the third sliding groove 30. The bottom end of the scraper 24 is in contact with the top end of the sieve plate 31. Due to the opening of the third sliding groove 30, the sieve plate 31 can slide up and down.

Due to the presence of the first locking block 19, it is convenient for the second locking block 20 to be inserted into the circular groove 16. The second locking block 20 is adjusted to... The second slot 15 is not a corresponding point, thus the mounting plate 18 can be effectively engaged to prevent displacement. When it needs to be disassembled later, the second locking block 20 is adjusted to the corresponding point of the second slot 15, and then it can be pulled out directly. When the stirring rod 22 is pulled, its support rod 23 can slide upward along the second slide 29, and the sieve plate 31 that is pushed can slide along the third slide 30, so that the sieve plate 31 can be taken out together, so that the user can perform separate maintenance and cleaning of the stirring rod 22 and the mixing tank 13 later.

The bottom end of the bolt 9 is threaded into the interior of the movable column 6 through the screw hole 8. The top frame 7 is threaded to the top of the movable column 6 through the screw hole 8 and the bolt 9. Due to the presence of the bolt 9, the screwing in of the bolt 9 can effectively fix the top frame 7 to prevent displacement. When the top frame 7 needs to be disassembled later, the bolt 9 can be unscrewed from the screw hole 8. This also facilitates the user's maintenance of the structure on the top frame 7 later.

[0031] refer to Figure 1 An electric push rod 11 is installed at the top of the support plate 1. A connecting plate 10 is fixedly connected to the inner wall of the movable column 6. The top of the electric push rod 11 is fixedly connected to the bottom of the connecting plate 10. A telescopic rod 12 is fixedly connected to the top of the support plate 1. The top of the telescopic rod 12 is fixedly connected to the bottom of the connecting plate 10. Due to the presence of the electric push rod 11, it is convenient for the user to push or pull the movable column 6 to move so as to adjust the height of the top frame 7. It is also convenient for the user to disconnect the connection point of the drive motor 32. The telescopic rod 12 includes a movable rod and a sleeve rod. The movable rod is sleeved inside the sleeve rod. The telescopic rod 12 can provide secondary support and traction to the bottom of the connecting plate 10 without hindering the adjustment of the height of the movable column 6, thereby effectively improving the stability of the height adjustment of the top frame 7.

[0032] refer to Figure 1 The bottom end of the support plate 1 is fixedly connected to the support leg 2, which is fixedly connected to the four sides near the corner of the bottom end of the support plate 1. The inner side of the support leg 2 is fixedly connected to the base frame 3, and the top of the base frame 3 is provided with a collection box 4. The position of the collection box 4 corresponds to the position of the discharge port of the mixing barrel 13. Due to the presence of the support leg 2, the bottom end of the support plate 1 can be effectively supported. The collection box 4 can collect the mixed material in the mixing barrel 13 in a unified manner so that the user can transfer and process it later.

[0033] Operating principle and advantages: During use, the mixing drum 13 facilitates the placement of materials, and its sieve plate 31 effectively supports the materials. Starting the drive motor 32 rotates the stirring rod 22, which in turn rotates the scraper 27. The scraper 24 continuously pushes the material at the top of the sieve plate 31, thus dispersing the material so that it can fall into the mixing drum 13 through the sieve plate 31, thereby improving the uniformity of material mixing. During the rotation of the stirring rod 22, its support rod 23 also drives the scraper 27 to rotate, scraping off any material adhering to the inner wall of the mixing drum 13, making it convenient and practical. The opening of the first chute 28 allows for precise control of the sliding points of the scraper 27. Effective traction improves the stability of the scraper 27's sliding position. The second groove 29 facilitates the user's disassembly of the support rod 23 and scraper 27. The third groove 30 facilitates the up-and-down sliding of the sieve plate 31, allowing it to be directly pulled out. The presence of the first locking block 19 facilitates the insertion of the second locking block 20 into the circular groove 16. Adjusting the second locking block 20 to a position that does not correspond to the second locking groove 15 effectively engages the mounting plate 18, preventing displacement. For later disassembly, adjust the second locking block 20 to correspond to the second locking groove 15 and then pull it out directly. Pull the stirring rod. At 22 o'clock, its support rod 23 can slide upward along the second slide groove 29, and the screen plate 31 that is pushed can slide along the third slide groove 30, thereby bringing the screen plate 31 out together, so that the user can perform separate maintenance and cleaning of the stirring rod 22 and the mixing tank 13 later. Due to the presence of the retaining spring 17, the retaining spring 17 can perform secondary locking at the second locking block 20 point, which can effectively improve the stability of the locking at the second locking block 20 point, and also effectively improve the stability of the locking at the mounting plate 18 point. Due to the presence of the bolt 9, the screwing in of the bolt 9 can effectively fix the top frame 7 point to prevent the top frame 7 from shifting. When the top frame 7 needs to be disassembled later, the bolt 9 can be screwed out of the screw hole 8, which also facilitates the user's later disassembly. During the maintenance of the top frame 7 structure, the presence of the electric push rod 11 facilitates the user to push or pull the movable column 6 to adjust the height of the top frame 7. It also facilitates the user to disconnect the connection point of the drive motor 32. The telescopic rod 12 includes a movable rod and a sleeve rod. The movable rod is sleeved inside the sleeve rod. The telescopic rod 12 can provide secondary support and traction to the bottom end of the connecting plate 10 without hindering the adjustment of the height of the movable column 6, thereby effectively improving the stability of the height adjustment of the top frame 7. The presence of the support leg 2 can effectively support the bottom end of the support plate 1. The collection box 4 can collect the mixed materials in the mixing tank 13 for the user to transfer and process later.
