Description

Technical Field

[0001] The utility model relates to a fry screening and separating device, belonging to the technical field of fry screening and separating. Background Art

[0002] For the breeding of fry, it is necessary to screen the fry before putting them into the pool. On the one hand, it can ensure the survival rate of the fry. On the other hand, the screened fry can be put and managed separately according to their sizes, so as to ensure that the fry will not have the situation of the weak being preyed on by the strong due to different sizes, increasing the mortality rate, thus increasing the cost investment. At the same time, it can also enable fry of different sizes to absorb the nutrients they should have at this growth stage, thereby achieving the effect of stable growth of the fry.

[0003] The existing fry sorting device screens the fry through a screening plate. However, the size of the screening plate is fixed, and the sizes of each batch of fry are not fixed. When screening different batches of fry, it may occur that the sizes of both small-sized and large-sized fry are smaller than the screening plate. At this time, the small and large fry in the same batch will be mixed together and cannot be effectively screened. It is also possible that the size of the small fry is larger than the screening plate, resulting in the situation that the small fry cannot be screened down. Therefore, the screening plate with a fixed size has great limitations in use. Summary of the Utility Model

[0027] Refer to Figure 2 , Figure 3 , Figure 4 and 5 , the screening mechanism further includes a sleeve 10 rotatably connected to the second support plate 22. A rotating shaft 9 is fixed at the bottom end of the sleeve 10. A second conical gear 8 is fixed at the bottom end of the rotating shaft 9. The second conical gear 8 meshes with the first conical gear 7. A threaded rod 11 is threadedly connected inside the sleeve 10. An internal thread matched with the threaded rod 11 is arranged on the inner wall of the sleeve 10. The end of the threaded rod 11 penetrating outside the sleeve 10 is fixed with a fixing plate 12. A fixing rod 23 is fixed at the bottom end of the fixing plate 12. The end of the fixing rod 23 penetrates into the breeding box 1 and is fixedly connected to the top end of the breeding frame 2. A limiting rod 24 is fixed at the middle bottom end of the two fixing plates 12. A limiting groove 25 is respectively opened on both inner walls of the breeding box 1. The end of the limiting rod 24 penetrates into the limiting groove 25. Through the setting of the screening mechanism, the screening mechanism can drive the breeding frame 2 to move upward. During this process, fry smaller than the size of the screening holes on the breeding frame 2 will pass through the breeding frame 2 and enter the inner bottom of the breeding box 1, and fry with a volume larger than the size of the screening holes on the breeding frame 2 will be left in the breeding frame 2, completing the screening of the fry.

[0028] Refer to Figure 2 , Figure 3 , Figure 4 and5 The breeding frame 2 includes a bottom plate 13 and a frame 14. An accommodation groove 15 is formed inside the bottom plate 13. A fixed frame 17 is fixed in the middle of the top end of the bottom plate 13. The bottom end of the fixed frame 17 communicates with the inside of the accommodation groove 15. An adjusting plate 16 is rotatably connected inside the accommodation groove 15. A connecting rod 18 is fixed in the middle of the top end of the adjusting plate 16. The end of the connecting rod 18 penetrates into the fixed frame 17. A rotating mechanism matching with the adjusting plate 16 is arranged on the inner top of the fixed frame 17. The rotating mechanism includes a driving gear 20 and a driven gear 21 rotatably arranged on the inner top of the fixed frame 17. The driving gear 20 meshes with the driven gear 21. The end of the driving gear 20 is connected to the output end of a second motor 19. The second motor 19 is fixed on the inner top of the fixed frame 17. The driven gear 21 is connected to the top of the connecting rod 18. Through the arrangement of the rotating mechanism, the rotating mechanism can adjust the diameter of the screening holes at the bottom of the breeding frame 2, so as to achieve screening different batches of fry according to the different volume sizes of the fry and improve the screening effect.

[0029] Refer to Figure 5 A through hole matching with the sleeve 10 is formed on the second support plate 22. A rotating block 26 is fixed on the outer surface of the sleeve 10. A rotating groove matching with the rotating block 26 is formed on the through hole. Through the arrangement of the through hole, the rotating block 26 and the rotating groove, the rotation stability of the sleeve 10 can be improved.

[0030] Refer to Figure 2 、 Figure 3 、 Figure 4 , A number of first screening holes are formed on the bottom plate 13 and the frame 14. A number of second screening holes are formed on the surface of the adjusting plate 16. The arrangement of the first screening holes and the second screening holes can screen the fry.

[0031] During use, pour the fry to be screened into the breeding frame 2. The breeding frame 2 is located inside the breeding tank 1. When screening, the screening mechanism can be started to drive the breeding frame 2 to move upward. During this process, the fry smaller than the size of the screening holes on the breeding frame 2 will pass through the breeding frame 2 and enter the inner bottom of the breeding tank 1, while the fry with a volume larger than the size of the screening holes on the breeding frame 2 will be left in the breeding frame 2, completing the screening of the fry. That is, by controlling the external switch to start the first motor 5, the output end of the first motor 5 drives the rotating rod 6 to rotate. The rotating rod 6 drives the two first bevel gears 7 to rotate. The two first bevel gears 7 rotate respectively to drive the meshing second bevel gears 8 to rotate. The second bevel gears 8 drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the sleeve 10 to rotate. Under the action of the limiting rod 24 and the limiting groove 25, the rotation of the sleeve 10 drives the threaded rod 11, the fixing plate 12 and the fixing rod 23 to move upward. The simultaneous upward movement of the two fixing rods 23 on both sides can drive the breeding frame 2 to move upward. As the breeding frame 2 moves, the fry will be screened. At this time, the screening of the fry can be completed. After screening, the bottom of the breeding frame 2 still remains in the water of the breeding tank 1;

[0032] Because the volume sizes of fry in different batches are different, when screening the fry, the aperture size of the screening holes at the bottom of the breeding frame 2 can be adjusted first, and then the fry can be screened according to the actual situation. That is, by controlling the external switch to start the second motor 19, the operation of the second motor 19 drives the driving gear 20 to rotate. The driving gear 20 rotates to drive the driven gear 21 to rotate. The driven gear 21 rotates to drive the connecting rod 18 to rotate. The connecting rod 18 drives the adjusting plate 16 connected thereto to rotate. The rotation of the adjusting plate 16 drives the screening holes two on the surface of the adjusting plate 16 to rotate, so that the size of the screening holes at the bottom of the breeding frame 2 can be adjusted. As the screening holes two rotate, when a part of the screening holes two coincides with the screening holes one, at this time, the diameter of the screening hole one on the surface of the bottom plate 13 becomes smaller. When the screening holes two completely coincide with the screening holes one, at this time, the diameter of the screening hole one on the surface of the bottom plate 13 becomes larger. Thus, when screening fry in different batches, screening can be carried out according to the different volume sizes of the fry, improving the screening effect.

[0033] Although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
