[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] See Figure 1-3An aquaculture feed preparation device is applied in the field of feed preparation technology. It can fully mix and crush raw materials, produce feed pellets with high consistency, and automatically clean the filter cartridge during the production process. Specifically, the system includes an outer cover 1, with support legs 29 installed at the bottom. A feed pipe 2 is connected to one side of the outer cover 1, and the feed inlet of the feed pipe 2 is equipped with a feed funnel for easy feeding. An annular limiting groove 3 is installed on the feed side of the outer cover 1, and the annular limiting groove 3 is rotatably connected to the filter barrel 4. This rotatable connection can be achieved using a bearing connection, and to prevent feed leakage, the bearing connection needs to have a certain degree of sealing and stain resistance. The filter barrel 4 is fixed to the inner wall of the outer cover 1 by a support device, which is an arc-shaped bracket 25 fixed to the inner wall of the outer cover 1. To facilitate the rotation of the filter barrel 4, small ball bearings 26 are also installed on the surface of the arc-shaped bracket 25. In this application, there are four arc-shaped brackets 25, installed at the four corners of the filter barrel 4, and the arc-shaped brackets 25 must not block the filter holes on the filter barrel 4. A cleaning device is installed on the inner wall of the outer cover 1, and a first motor 5 is installed on the other side of the outer cover 1, extending to the filter barrel. The filter barrel 4 is internally connected to a stirring shaft 6, on which blades 7 are mounted. To improve crushing efficiency, the blades 7 are arranged in a staggered, multi-group pattern. Several cutting plates 27 are mounted on the inner wall of the filter barrel 4, which work in conjunction with the blades 7 and rotate in opposite directions during operation, significantly improving crushing efficiency. The stirring shaft 6 and the filter barrel 4 are connected by a rotating connection, specifically using bearings with high anti-fouling properties. A filter barrel drive device is also connected between the stirring shaft 6 and the filter barrel 4, which can drive the filter barrel 4 to rotate, requiring only a single motor. The bottom of the outer cover 1 is connected to a screw conveyor via a funnel 8. A slide plate 28 is mounted on the bottom of the outer cover 1, which can slide the filtered and crushed feed into the funnel 8. An extrusion plate 9 is mounted at the end of the screw conveyor, and a feed segmentation device is mounted on the extrusion plate 9. The small holes on the extrusion plate 9 can extrude the feed into long strips, which are then cut into small segments of similar length by the feed segmentation device. When in use, this application has high crushing efficiency, a self-cleaning function, and can automatically cut feed into segments, which can significantly improve the production efficiency and product quality of aquatic feed.

[0025] In this invention, the filter cartridge drive device includes a drive gear 10 fixedly sleeved on the stirring shaft 6. The drive gear 10 meshes with a driven gear 11, which is rotatably connected to a fixed rod 12. The fixed rod 12 is installed on the inner wall of the outer cover 1. An annular internal gear 13 is installed on the side of the filter barrel 4, meshing with the driven gear 11. During operation, the first motor 5 drives the drive gear 10 to rotate, and the drive gear 10 drives the filter barrel 4 to rotate through the driven gear 11. A single motor can simultaneously drive the stirring shaft 6 and the filter barrel 4 to rotate, and can ensure that they rotate in opposite directions, thereby enhancing the pulverization efficiency.

[0026] In this utility model, the screw conveyor device includes a conveyor housing 14 connected to the funnel 8. The conveyor housing is fixed to the bottom of the outer cover 1 by a pull plate 17. Because the screw conveyor device is long and has a certain mass, it cannot be fixed by the funnel 8 alone. Therefore, the pull plate 17 is used to fix it to the bottom of the outer cover 1. The conveyor housing 14 is provided with a screw conveyor shaft 15. The screw conveyor shaft 15 has a gradually denser thread. The gradually denser thread can make the feed more compact during the conveying process and prevent it from loosening when discharging. The screw conveyor shaft 15 is driven by a second motor 16 installed on the conveyor housing 14. The second motor 16 drives the screw conveyor shaft 15 to rotate. The production speed can be adjusted by adjusting the speed of the second motor 16.

[0027] In this utility model, the feed segmentation device includes a third motor 18 installed on the conveyor housing 14. The third motor 18 is connected to a gear 19, which meshes with an external ring gear 20. A cutting plate 21 is installed on the external ring gear 20. The external ring gear 20 is rotatably installed on the conveyor housing 14. The external ring gear 20 and the conveyor housing 14 can be connected by bearings. The external ring gear 20 needs to be as close as possible to the end of the conveyor housing 14 to facilitate the installation of the cutting plate 21. The cutting plate 21 passes through the external ring gear 20, and its center does not contact the extrusion plate to prevent material jamming. The cutting plate 21 is in close contact with the surface of the extrusion plate 9, which can more smoothly cut the feed into segments and prevent defects in the feed cut.

[0028] In this utility model, the cleaning device includes a fixing strip 22 fixed on the inner wall of the outer cover 1. A scraper 23 is installed on the fixing strip 22 through a slot. A brush 24 is installed at the end of the scraper 23. The slot connection method allows for easy replacement and cleaning of the scraper 23 and the brush 24. In use, the scraper 23 can clean the surface of the filter barrel 4, and the brush 24 can perform deep cleaning of the pores. The combination of the two can significantly improve the cleanliness of the filter barrel 4.

[0029] As can be seen from the above technical solution, during use, the feed ingredients are mixed and fed into the feed pipe 2. The first motor 5 is started, which drives the stirring shaft 6 to rotate. The stirring shaft 6 drives the blades 7 to rotate inside the filter barrel 4. At the same time, the stirring shaft 6 drives the filter barrel 4 to rotate in reverse through the driving gear 10 and the driven gear 11. The inner wall of the filter barrel 4 is equipped with a cutting plate 27. The cutting plate 27 and the blades 7 work together to crush the feed. While the filter barrel 4 is rotating, the brushes on both sides of the filter barrel 4 can clean its surface to prevent the filter barrel 4 from clogging. The crushed feed passes through the filter barrel 4. The feed is fed into hopper 8, which then feeds it into the screw conveyor. The second motor 16 is started, which drives the screw conveyor shaft 15 to rotate. The spacing of the screw conveyor shaft 15 decreases gradually, which can compact the feed during the conveying process. When the feed is conveyed to the end of the screw conveyor, it will be squeezed out from the holes of the extrusion plate 9. The third motor 18 is then started. The third motor 18 drives the cutting plate 21 to rotate through the ring external gear 20. The cutting plate 21 can continuously cut the feed squeezed out from the extrusion plate 9 to ensure the consistency and appearance of the feed. This completes a single production process.

[0031] It should be understood that this utility model is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
