[0002] Laboratory animal feed is specially formulated according to the species, physiological characteristics, growth stage and corresponding scientific research requirements of laboratory animals. It contains a precise ratio of various nutrients to maintain the health of laboratory animals and ensure the smooth conduct of experiments. The screening production device is a device used to screen feed so that the screened feed meets the requirements for laboratory animal husbandry.

[0003] Existing feed screening and production equipment is often equipped with only a single-size screen or uses a simple linear vibrating screen structure. This means that when processing feed pellets, only feed pellets within a specific particle size range can be screened. This requires multiple screenings of the feed pellets to effectively remove larger and smaller particles separately to ensure uniformity in feed particle size. This is insufficient to meet the needs of modern laboratory animal husbandry for efficient and precise feed preparation. Therefore, an improvement is needed. To this end, a screening and production device for laboratory animal feed is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] A screening and production device for laboratory animal feed includes a screening box 1, which is cylindrical in shape. A feeding hopper 2 is fixedly installed on the top of the screening box 1. Filter balls 3 are fixedly installed inside the top of the screening box 1. The bottom of the feeding hopper 2 is connected to the top of the filter balls 3. A crossbar 4 is rotatably arranged inside the screening box 1, and the crossbar 4 is rotatably positioned in the middle of the filter balls 3. Evenly distributed and symmetrical stirring rods 5 are arranged inside the filter balls 3, and the ends of the stirring rods 5 are all fixedly installed to the crossbar 4. A filter plate 6 is arranged at the bottom of the screening box 1. The filter plate 6 is arc-shaped, and the mesh size of the filter plate 6 is smaller than the mesh size of the filter balls 3. A second crossbar 7 is rotatably arranged inside the screening box 1, and evenly distributed and symmetrical stirring rods 8 are fixedly installed on the second crossbar 7. Each row of stirring rods 8 has an arc-shaped end fixedly installed. The screen box 1 has a filter plate 6 with an arc that matches the arc of the filter plate 6. The side of the screen box 1 is provided with a drive mechanism 10 for driving the stirring rod 5, the stirring rod 8, and the arc plate 9 to rotate and screen simultaneously. The bottom of the screen box 1 is provided with a collection box 11, and the filter plate 6 is directly opposite the opening of the collection box 11. The drive mechanism 10 includes a drive motor 101 fixedly installed on the side of the screen box 1, a drive wheel 102 and a driven wheel 103 rotatably installed on the side of the screen box 1, and a belt 104 sleeved on the drive wheel 102 and the driven wheel 103. The output shaft end of the drive motor 101 is fixedly installed with the shaft end of the crossbar 4, the shaft end of the drive wheel 102 is fixedly installed with the shaft end of the crossbar 4, and the shaft end of the driven wheel 103 is fixedly installed with the shaft end of the crossbar 7. The belt 104 is connected to the drive wheel 102 and the driven wheel 103 respectively.

[0032] When using the screening and production device for laboratory animal feed, firstly, feed of different particle sizes is fed from the feeding port of the screening box 1, and the feed particles directly enter the filter ball 3 from the feeding hopper 2.

[0033] Start the drive motor 101 on the side of the screening box 1. The output shaft of the drive motor 101 rotates and drives the crossbar 4 to rotate. The rotation of the crossbar 4 causes the stirring rod 5, which is fixedly connected to it, to rotate synchronously inside the filter ball 3. The rotation of the stirring rod 5 agitates the feed particles inside the filter ball 3. Under the combined action of gravity and stirring force, medium and small particles pass through the mesh holes of the filter ball 3 and fall onto the arc-shaped filter plate 6, while larger particles are left inside the filter ball 3.

[0034] During the rotation of the crossbar 4, the drive wheel 102 rotates synchronously. The drive wheel 102 drives the driven wheel 103 to rotate via the belt 104. The rotation of the driven wheel 103 drives the crossbar 7 to rotate. The stirring rod 8 and the arc plate 9 fixed on the crossbar 7 rotate accordingly. When the feed particles fall onto the filter plate 6, the rotation of the stirring rod 8 and the arc plate 9 further screens the particles on the filter plate 6. At this time, smaller particles pass through the mesh holes of the filter plate 6 and enter the collection box 11 for collection. Medium-sized particles that meet the requirements will remain on the filter plate 6. After that, particles of all sizes can be used.

[0035] This experimental animal feed screening and production device can efficiently and easily screen out both oversized and undersized particles in the feed pellets, ensuring that the obtained feed has a uniform particle size and meeting the specific needs of experimental animals for feed particle size. The device has a simple overall structure, is easy to operate, and is highly practical.

[0036] A frame 12 is provided at the bottom of the screening box 1. The screening box 1 is rotatably mounted on the frame 12. A deflection motor 13 is fixedly installed on the side of the frame 12. The shaft end of the deflection motor 13 is fixedly installed with the shaft end of the screening box 1. An arc-shaped sealing plate 14 is snapped onto one side of the screening box 1. The arc-shaped sealing plate 14 faces the filter plate 6. A strip-shaped sealing plate 15 is snapped onto the side of the collection box 11. An inclined tube 16 is provided on the bottom side of the filter ball 3. A switch valve 17 is provided on the inclined tube 16.

[0037] After the screening process is completed, to collect particles of various sizes, start the deflection motor 13 on the side of the frame 12. The deflection motor 13 drives the screening box 1, the arc-shaped sealing plate 14, and the strip-shaped sealing plate 15 to deflect to a certain angle. At this time, medium and small particles of feed roll towards the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15, opening the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15 respectively, so that medium and small particles of feed can be discharged separately. When discharging large particles of feed in the filter ball 3, open the switch valve 17 on the inclined tube 16. The large particles of feed roll down from the inclined tube 16 to the opening of the arc-shaped sealing plate 14 through the inclined filter ball 3 for discharge. It can discharge uniform particles, large particles, and small particles after screening, improving discharge efficiency and making it highly practical.

[0038] A receiving box 18 is provided on the frame 12;

[0039] The receiving box 18 is designed to collect the discharged feed pellets.

[0040] Both the arc-shaped sealing plate 14 and the strip sealing plate 15 are fixedly installed with handles 19;

[0041] Both the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15 are fixedly installed with handles 19, which facilitates easy disassembly and assembly of the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15 by operators.

[0042] Working principle:

[0043] When using the screening and production device for laboratory animal feed, firstly, feed of different particle sizes is fed from the feeding port of the screening box 1, and the feed particles directly enter the filter ball 3 from the feeding hopper 2.

[0044] Start the drive motor 101 on the side of the screening box 1. The output shaft of the drive motor 101 rotates and drives the crossbar 4 to rotate. The rotation of the crossbar 4 causes the stirring rod 5, which is fixedly connected to it, to rotate synchronously inside the filter ball 3. The rotation of the stirring rod 5 agitates the feed particles inside the filter ball 3. Under the combined action of gravity and stirring force, medium and small particles pass through the mesh holes of the filter ball 3 and fall onto the arc-shaped filter plate 6, while larger particles are left inside the filter ball 3.

[0045] During the rotation of the crossbar 14, the drive wheel 102 rotates synchronously. The drive wheel 102 drives the driven wheel 103 to rotate via the belt 104. The rotation of the driven wheel 103 drives the crossbar 27 to rotate. The stirring rod 28 and the arc plate 9 fixed on the crossbar 27 rotate accordingly. When the feed particles fall onto the filter plate 6, the rotation of the stirring rod 28 and the arc plate 9 further screens the particles on the filter plate 6. At this time, smaller particles pass through the mesh holes of the filter plate 6 and enter the collection box 11 for collection. Medium-sized particles that meet the requirements will remain on the filter plate 6.

[0046] After the screening process is completed, to collect particles of various sizes, start the deflection motor 13 on the side of the frame 12. The deflection motor 13 drives the screening box 1, the arc-shaped sealing plate 14, and the strip-shaped sealing plate 15 to deflect to a certain angle. At this time, medium-sized and small-sized feed particles roll towards the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15, opening the arc-shaped sealing plate 14 and the strip-shaped sealing plate 15 respectively, so that the medium-sized and small-sized feed particles can be discharged respectively. When discharging the large-sized feed particles in the filter ball 3, open the switch valve 17 on the inclined tube 16. The large-sized feed particles roll down from the inclined tube 16 to the opening of the arc-shaped sealing plate 14 through the inclined filter ball 3 for discharge.

[0047] This experimental animal feed screening and production device can efficiently and easily screen out both oversized and undersized particles in the feed pellets, ensuring that the obtained feed has a uniform particle size and meeting the specific needs of experimental animals for feed particle size. The device has a simple overall structure, is easy to operate, and is highly practical.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
