[0002] Aquaculture refers to the production activities of cultivating, breeding, and raising aquatic organisms such as fish, shrimp, crabs, shellfish, and algae in various aquatic environments (such as ponds, lakes, rivers, and oceans) under human control to obtain aquatic products. Fish fry in aquaculture refer to small fish that hatch from fish eggs, and are called "fry" during their first few months of life. These fry are the foundation of farmed fish and a key link in achieving sustainable development of fisheries. During the growth process of aquaculture fry, a screening device is needed to prevent larger fry from competing for more food resources, causing smaller fry to grow slowly or even stunt due to lack of food.

[0003] Aquaculture fry screening devices are specially designed to automatically separate and screen fry of different sizes, health conditions, and vitality. In traditional technology, the screen is usually fixed to the screening box with bolts and nuts. This method of installation and disassembly is too cumbersome and inconvenient to maintain or replace the screen, which affects the screening quality of the fry. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a fish fry screening device for aquaculture, comprising a box 1, a screen 2 slidably connected to the inner wall of the box 1, a screen 3 slidably connected to the inner wall of the box 1, mounting blocks 4 fixedly connected to the outer walls of both screen 2 and screen 3, a hollow block 5 slidably connected to the inner wall of the mounting block 4, the outer wall of the hollow block 5 fixedly connected to the outer wall of the box 1, a handle 6 slidably connected to the inside of the hollow block 5, a transmission block 7 fixedly connected to the outer wall of the handle 6, a spring 8 fixedly connected to the lower surface of the transmission block 7, the lower outer wall of the spring 8 fixedly connected to the inner wall of the hollow block 5, and the upper surface of the transmission block 7... A fixing rod 9 is provided, and an L-shaped rod 10 is slidably connected to the outer wall of the fixing rod 9. The upper outer wall of the L-shaped rod 10 is slidably connected to the inner wall of the mounting block 4, and a limiting rod 11 is fixedly connected to the lower outer wall of the L-shaped rod 10. The outer wall of the limiting rod 11 is slidably connected to the inner wall of the hollow block 5. A water spray assembly is provided on the outer wall of the box 1. The water spray assembly is used to push the water inside the box 1. The water spray assembly includes a water pump 12. The outer wall of the water pump 12 is fixedly connected to the outer wall of the box 1. One end of the water pump 12 is fixedly connected to the inside of the box 1, and the other end of the water pump 12 is provided with a water tank 13. The outer wall of the water tank 13 is fixedly connected to the outer wall of the box 1.

[0025] Specifically, the holes of screen 2 3 are smaller than those of screen 1 2, used to distinguish the size of fish fry. The outer wall of the hollow block 5 positions the installation block 4. The inner wall of the hollow block 5 is provided with a guide groove, which allows the limit rod 11 to slide along the guide groove when the handle 6 and the transmission block 7 press down. This causes the L-shaped rod 10 to rotate towards the center of the transmission block 7 when it moves downward. The outer wall of the L-shaped rod 10 is provided with a short rod, which is used to reset the L-shaped rod 10 under the elastic force of the handle 6 and the spring 8 when it is lifted upward, thereby limiting the installation block 4 and facilitating the installation of screen 1 2 and screen 2 3. The water pump 12 is started to draw water from the water tank 13, thereby pushing the water inside the tank 1, thus pushing the fish fry from right to left to screen the fish fry. A drain pipe is provided on the left side of the tank 1 for draining when there is too much water in the tank 1.

[0026] Reference Figure 3 Both ends of the fixed rod 9 are fixedly connected to the inner wall of the hollow block 5, the outer wall of the L-shaped rod 10 is slidably connected to the inner wall of the hollow block 5, and the outer wall of the limiting rod 11 is set on the lower surface of the transmission block 7.

[0027] Specifically, the hollow block 5 fixes the fixed rod 9, the inner wall of the hollow block 5 limits the rotation of the L-shaped rod 10, and the limiting rod 11 is located on the lower side of the transmission block 7, which facilitates the transmission block 7 to transmit the limiting rod 11.

[0028] Reference Figure 4A base 14 is provided on the lower surface of the housing 1. A fixing frame 15 is fixedly connected to the upper surface of the base 14. The outer wall of the fixing frame 15 is rotatably connected to the inside of the housing 1. A motor 16 is fixedly connected to the upper surface of the base 14. A lead screw 17 is fixedly provided at the output end of the motor 16. A fixing plate 18 is rotatably connected to the outer wall of the lead screw 17. The lower surface of the fixing plate 18 is fixedly connected to the upper surface of the base 14. A transmission frame 19 is threadedly connected to the outer wall of the lead screw 17. Connecting plates 20 are rotatably connected to both outer walls of the transmission frame 19. A support rod 21 is fixedly connected inside the connecting plate 20. Both ends of the support rod 21 are rotatably connected to the inside of the housing 1. A telescopic frame 22 is rotatably connected inside the base 14. The upper outer wall of the telescopic frame 22 is rotatably connected to the inside of the housing 1.

[0029] Specifically, motor 16 drives lead screw 17, which in turn drives transmission frame 19 to move. Fixed plate 18 supports the rotation of lead screw 17. As transmission frame 19 moves, connecting plate 20 and support rod 21 push box 1 upward. Under the limit of fixed frame 15, box 1 rotates to the left. Short rods are provided on both the upper and lower sides of telescopic frame 22, which rotate inside box 1 and base 14, thereby limiting the rotation of box 1. Counterweight and fixed column are provided on the right side of base 14. Counterweight is used to prevent base 14 from becoming unstable when box 1 rotates. Fixed column is used to support box 1 after it is reset. Universal wheels are provided on the lower surface of base 14 to facilitate the movement of the entire device.

[0030] Working principle: When using this device, a suitable amount of water is stored inside the box 1. Fish fry are placed on the far right side of the box 1. The water pump 12 is started to draw water from the water tank 13, guiding the water flow inside the box 1. The water flow from right to left pushes the fish fry. Under the action of screen 1 2 and screen 2 3, the largest fish fry move on the far right side of the box 1, the medium-sized ones move in the middle of the box 1, and the smallest ones move on the far left side of the box 1, thus screening the fish fry. The motor 16 drives the lead screw 17, causing the transmission frame 19 to move to the left. Under the action of the box 1 and the support rod 21, the connecting plate 20 pushes the box 1 upwards through the transmission frame 19. Under the limit of the fixed frame 15, the box 1 flips to the left, thereby adjusting the angle at which the box 1 screens the fish fry. The telescopic frame 22... The device is used to limit the movement of the box 1 when it is flipped. When maintenance is required on screen 1 2 and screen 2 3, pressing the handle 6 moves the transmission block 7 downward to compress the spring 8. When the transmission block 7 moves the limiting rod 11 downward, it slides along the inner wall of the hollow block 5. When the limiting rod 11 moves the L-shaped rod 10 downward, the fixing rod 9 limits the L-shaped rod 10, causing the L-shaped rods 10 on both sides to rotate toward the center of the transmission block 7 and move downward, thereby releasing the mounting block 4. This achieves the effect of quickly disassembling screen 2 3 and screen 1 2. During use, this device can not only quickly install and disassemble screen 1 2 and screen 2 3, making it easy for maintenance personnel to quickly remove them for cleaning or replacement, thus ensuring screening quality, but also adjust the angle of the box 1 to optimize water flow and fish fry distribution.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
