The top of the partition plate 5 is provided with a discharge hole 8, and the sealing plate 7 forms a sliding fit with the discharge hole 8. The sealing plate 7 can block the gap formed between the discharge hole 8 and the sliding hole 6. When the discharge hole 8 at the top of the partition plate 5 slides to the outside of the feed hopper 2, it can prevent the material in the feed hopper 2 from flowing out of the sliding hole 6.

[0040] By controlling the positions of the two partition plates 5 inside the feed hopper 2, a suitable amount of material can be added at once without the need for multiple additions and subtractions, which greatly simplifies the operation process, reduces operation time and labor costs, improves mixing efficiency, and can quickly discharge the material between the two partition plates 5, achieving rapid unloading.

[0041] In this embodiment, as Figure 2As shown, multiple diversion plates 9 are fixedly connected to the two inclined sections of the feed box 1.

The multiple diversion plates 9 can convey the material in layers, so that the material in the feed box 1 can be contacted in layers and premixed.

[0042] In this embodiment, as Figure 4 and Figure 5 As shown, a feeding pipe 12 is fixedly connected to the bottom of the feeding box 1, and a stirring shaft 16 is rotatably connected to the inner wall of the feeding pipe 12. Multiple stirring blades 18 are provided inside the feeding box 1. The stirring blades 18 are driven to rotate by the toothed ring 14, thereby improving the stirring effect and promoting the full mixing of materials.

[0043] In this embodiment, as Figure 4 and Figure 5 As shown, the top of the feed box 1 is fixedly connected to the mounting plate 10, the top of the stirring shaft 16 passes through the feed box 1 and extends above it, and the inner wall of the mounting plate 10 is fixedly connected to the first stepper motor 11, the output end of the first stepper motor 11 is fixedly connected to the stirring shaft 16.

[0044] In this embodiment, as Figure 5 As shown, the outer wall of the feed pipe 12 is provided with multiple discharge ports 17, and the outer wall of the stirring shaft 16 is fixedly connected with a dispersing blade 19; the dispersing blade 19 can diffuse the mixed material through the discharge ports 17. The feed pipe 12 is connected to the mixing device, and the material discharged through the feed pipe 12 can be fully dispersed in the mixing device, which facilitates the mixing of materials.

[0045] In this embodiment, as Figure 5 and Figure 7 As shown, multiple fixing brackets 13 are fixedly connected to the outer wall of the feeding pipe 12, and multiple gaps 1201 are provided on the outer wall of the feeding pipe 12. A toothed ring 14 is provided on the inner wall of each gap 1201. A rotating sleeve 15 is fixedly connected to the top and bottom of the toothed ring 14. The rotating sleeve 15 is rotatably connected to the inner wall of the feeding pipe 12, and the inner wall of the toothed ring 14 is fixedly connected to the stirring blade 18.

[0046] In this embodiment, as Figure 5 and Figure 6 As shown, it also includes a drive assembly, which includes a second stepper motor 20. The second stepper motor 20 is fixedly installed on the outer wall of the feed tube 12. The output end of the second stepper motor 20 is fixedly connected to a drive shaft 22. Two support plates 21 are rotatably connected to the end of the drive shaft 22. A rotating shaft 23 is rotatably connected between the two support plates 21. A first gear 24 is fixedly connected to the outer wall of the drive shaft 22. A second gear 25 is fixedly connected to the outer wall of the drive shaft 22. The second gear 25 and the first gear 24 are staggered. A third gear 26 is fixedly connected to the outer wall of the rotating shaft 23. The second gear 25 and the third gear 26 mesh. The first gear 24 and the third gear 26 mesh with the gear ring 14 respectively.

[0047] The first gear 24 and the third gear 26 can drive the adjacent gear ring 14 to rotate rapidly in opposite directions. The gear ring 14 drives the stirring blade 18 to rotate, thereby improving the stirring effect and promoting the full mixing of materials.

[0048] Working principle: The material is fed into the feed hopper 2. The material flows through the upper partition plate 5 in the feed hopper 2 and is blocked by the lower partition plate 5 in the feed hopper 2. The distance between the two partition plates 5 in the feed hopper 2 can be set according to the required amount of material.

[0049] The upper double piston cylinder 4 drives the upper partition plate 5 to slide along the inner wall of the sliding hole 6 in the feed hopper 2. The sealing plate 7 can block the gap formed between the discharge hole 8 and the sliding hole 6. At this time, when the discharge hole 8 at the top of the partition plate 5 slides to the outside of the feed hopper 2, it can prevent the material in the feed hopper 2 from flowing out of the sliding hole 6.

[0050] When the sliding hole 6 moves into the feed hopper 2, the amount of material between the two partition plates 5 is matched. The lower double piston cylinder 4 drives the lower partition plate 5 to slide into the feed hopper 2 until the discharge hole 8 moves into the feed hopper 2, and the material in the feed hopper 2 flows downward quickly.

[0051] When the material enters both ends of the guide box 1, it can be conveyed in layers by multiple diversion plates 9, so that the material in the guide box 1 can be in contact with each other and premixed.

[0052] The second stepper motor 20 drives the first gear 24 to rotate via the drive shaft 22. The drive shaft 22 drives the third gear 26 to rotate via the second gear 25. Since the first gear 24 and the third gear 26 rotate in opposite directions, the first gear 24 and the third gear 26 can drive the adjacent gear ring 14 to rotate rapidly in opposite directions, and the gear ring 14 drives the stirring blade 18 to rotate.

[0053] The premixed material enters the feed pipe 12. The first step motor 11 drives the stirring shaft 16 to rotate, and the stirring shaft 16 drives the dispersing blades 19 to rotate, so that the mixed material can be diffused out through the discharge port 17.

[0054] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
