Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture, and in particular to a fish fry screening device for aquaculture. Background Technology

[0002] Fish fry screening is an essential process in aquaculture. Generally, fish fry need to be screened before being released into the pond to separate fry of different sizes, preventing larger fish from preying on smaller ones and competing for food, which would affect the survival rate of the smaller fry. Existing technology announcement number CN218649755U discloses a fish fry screening device for aquaculture, including a support platform, a water tank connected to the upper end of the support platform, a screener connected to one end of the water tank, a fry inlet connected to the upper end of the screener, a partition net installed inside the screener, a water pump installed inside the screener, a water pipe connected to one end of the screener, a first insertion hole on the surface of the screener, a first screening plate connected inside the first insertion hole, a first sieve hole inside the first screening plate, a first handle connected to the upper end of the first screening plate, and a second insertion hole on the surface of the screener, with a second screening plate connected inside the second insertion hole. However, during use, the fish fry must be scooped out of the filter after screening. Each time the fish fry are screened, they must be removed from the filter before the next screening can be carried out. The operation is too cumbersome and the fish fry are easily injured during the scooping process, which reduces the screening efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an aquaculture fry screening device that can accelerate the screening of fry, avoid damage to fry during catching, and improve screening efficiency.

[0004] This utility model discloses a fish fry screening device for aquaculture, comprising a screening box, multiple support legs, multiple friction bases, two screening screens, a lifting assembly, a sealing component, a collecting assembly, a feeding assembly, and a feeding component. Support legs are installed on the left and right side walls at the bottom of the screening box, and friction bases are installed at the bottom of the support legs. A partition is provided in the middle of the screening box, making the upper part of the screening box a screening chamber and the lower part a collecting chamber. Two screening screens are installed in the screening chamber, with the aperture of the left screening screen being larger than that of the right screening screen. The lifting assembly is installed on the outer wall of the screening box, and a lifting component is mounted on the lifting assembly. Equipped with a sealing component, the collection assembly is installed inside the collection chamber, a feeding component is installed on the side wall of the screening box, and a feeding component is installed on the lifting assembly. Fish fry are added to the leftmost chamber of the screening chamber through the feeding component, and the fish fry are screened by two screening screens. The feeding component can spread fish bait into the screening chamber, which helps to speed up the screening of fry. After screening, the sealing component is moved upward by the lifting assembly, so that the fish fry in each chamber of the screening chamber fall into the collection assembly, thereby avoiding the situation of catching fish fry and causing damage, thus improving the screening efficiency.

[0005] Preferably, the lifting assembly includes two electric telescopic rods, two push plates, and a crossbeam. The two electric telescopic rods are respectively installed on the outer walls of the left and right sides of the screening box. The top telescopic end of the electric telescopic rod is equipped with a push plate, and a crossbeam is installed between the two push plates. The crossbeam is located above the screening box. When the electric telescopic rod is activated, it pushes the crossbeam upward through the push plates, which can complete the release of fish fry.

[0006] Preferably, the sealing component includes multiple vertical rods, multiple sealing cylinders, multiple sealing blocks, and multiple 26s. The multiple vertical rods are respectively installed at the bottom of the crossbeam. 26s are installed between the outer wall of the vertical rod and the crossbeam. Sealing cylinders are installed at the bottom of the vertical rods. The top of the partition has a groove that matches the sealing cylinder, and the top of the partition has a discharge port. Sealing blocks are installed at the bottom of the sealing cylinders, and the sealing blocks are sealed to the discharge port. During screening, the discharge port is sealed by the sealing cylinders and sealing blocks. After screening, the crossbeam moves the sealing cylinders upward through the vertical rods, causing the sealing blocks to move out of the discharge port. This allows the fish fry to be discharged directly downwards without needing to be retrieved from the screening box after screening, avoiding damage to the fish fry during retrieval and thus improving screening efficiency.

[0007] Preferably, the feeding assembly includes two feeding cylinders, two hoppers, two servo motors, two rotating rods, and two sets of spiral blades. The two feeding cylinders are mounted on the top of the crossbeam, above the two chambers on the right side of the screening chamber. Feeding holes are opened on the front and rear sides of the bottom of the feeding cylinders. A hopper is installed on the top of the feeding cylinder. A rotating rod is rotatably installed inside the feeding cylinder. Spiral blades are symmetrically installed on the front and rear sides of the rotating rod. The input end of the rotating rod is connected to the output end of the servo motor. When the bait is placed inside the hopper, the servo motor is started to drive the rotating rod to rotate. The rotating rod drives the two spiral blades to rotate, pushing the bait forward and backward to the front and rear sides and falling into the screening chamber through the feeding holes. As time increases, the left servo motor is turned off, allowing the smallest fry to pass through the right end screening plate and swim to the rightmost chamber, thus accelerating the screening of fry and improving screening efficiency.

[0008] Preferably, the collection components include multiple collection boxes, multiple limiting rods, multiple sets of casters, and multiple handles. The collection chamber and the screening chamber are configured as three chambers. Limiting slots are opened on the inner walls of the left and right sides of the collection chamber. Limiting rods are installed on the left and right sides of the collection boxes. Multiple casters are installed at the bottom of the collection boxes. A handle is connected to the front end of the collection boxes. Fish fry of different sizes are collected separately by using multiple collection boxes. Pulling the handles allows the collection boxes to be pulled out of the collection chamber for subsequent processing. The limiting rods and limiting slots can be used to position the collection boxes to ensure connection stability.

[0009] Preferably, the feeding assembly includes a feeding trough, multiple support rods, a water distribution pipe, and multiple water outlets. The feeding trough is installed on the left side of the rear side wall of the screening box, and multiple feeding troughs are fixedly connected between the bottom of the feeding trough and the rear side wall of the screening box. The water distribution pipe is installed on the left side of the front side wall of the screening box, and multiple water outlets are installed on the water distribution pipe. The fish fry to be screened are poured into the feeding trough, and the fish fry are guided into the screening chamber through the feeding trough, which improves the convenience of feeding. At the same time, the input end of the water distribution pipe is connected to the water pipe, and the water distribution pipe and water outlets facilitate the replenishment of water into the screening chamber.

[0010] Preferably, it also includes two support plates and two guide rods. The support plate is installed at the top of the electric telescopic rod, and the guide rods are slidably installed at the front and rear ends of the support plate. The top of the guide rods is connected to the bottom of the push plate. When the push plate moves up and down, it drives the guide rods to slide on the support plate, which guides and limits the push plate, enhances the structural strength, and improves the stability.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the fish fry are added to the leftmost chamber of the screening chamber by the feeding component, and the fish fry are screened by two screening screens. The feeding component can spread fish bait into the screening chamber, which helps to speed up the screening of fry. After the screening is completed, the lifting component drives the sealing component to move upward, so that the fish fry in each chamber of the screening chamber fall into the collection component, thereby avoiding the situation of harming the fish fry when catching them, thus improving the screening efficiency.

[0019] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0020] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, support legs 2 are installed on the left and right side walls at the bottom of the screening box 1. Friction bases 3 are installed at the bottom of the support legs 2. A partition is set in the middle of the screening box 1, so that the upper part of the screening box 1 is the screening chamber and the lower part is the collection chamber. Two screening screens 4 are installed in the screening chamber. The aperture of the left screening screen 4 is larger than that of the right screening screen 4. Two electric telescopic rods 5 are respectively installed on the left and right outer walls of the screening box 1. Push plates 6 are installed at the top telescopic ends of the electric telescopic rods 5. A crossbeam 7 is installed between the two push plates 6. The crossbeam 7 is located above the screening box 1. Multiple vertical rods 8 are respectively installed. At the bottom of the crossbeam 7, 26 is installed between the outer wall of the vertical rod 8 and the crossbeam 7. A sealing cylinder 9 is installed at the bottom of the vertical rod 8. A groove matching the sealing cylinder 9 is opened at the top of the partition, and an outlet is opened at the top of the partition. A sealing block 10 is installed at the bottom of the sealing cylinder 9. The sealing block 10 is sealed and fitted with the outlet. The collection chamber and the screening chamber are set as three chambers. Limit slots are opened on the inner walls of the left and right sides of the collection chamber. Limit rods 19 are installed on the left and right sides of the collection box 18. Multiple moving wheels 20 are installed at the bottom of the collection box 18. A handle 21 is connected to the front end of the collection box 18.

[0021] Fish fry are added to the leftmost chamber of the screening chamber and screened by two screening screens 4. During screening, the outlet is blocked by the sealing cylinder 9 and the sealing block 10. After screening, the crossbeam 7 moves the sealing cylinder 9 upward through the vertical rod 8, thereby moving the sealing block 10 out of the outlet. This allows the fish fry to be discharged directly downward without needing to be retrieved from the screening box 1, avoiding damage to the fish fry during retrieval and improving screening efficiency. Fish fry of different sizes are collected separately by multiple collection boxes 18. Pulling the handle 21 pulls the collection box 18 out of the collection chamber for subsequent processing. The limit rod 19 and the limit slot can be used to position the collection box 18 to ensure connection stability. Example 2

[0022] like Figure 2 , Figure 4 and Figure 6 As shown, based on embodiment 1, it also includes two spreading cylinders 13 mounted on the top of the crossbeam 7, located above the two chambers on the right side of the screening chamber. Spreading holes are opened on the front and rear sides of the bottom of the spreading cylinders 13. A hopper 14 is installed on the top of the spreading cylinders 13. A rotating rod 16 is rotatably installed inside the spreading cylinders 13. Spiral blades 17 are symmetrically installed on the front and rear sides of the rotating rod 16. The input end of the rotating rod 16 is connected to the output end of the servo motor 15. The feeding trough 22 is installed on the left side of the rear side wall of the screening box 1. Multiple feeding troughs 22 are fixedly connected between the bottom of the feeding trough 22 and the rear side wall of the screening box 1. The water distribution pipe 24 is installed on the left side of the front side wall of the screening box 1. Multiple water outlets 25 are installed on the water distribution pipe 24. A support plate 11 is installed on the top of the electric telescopic rod 5. Guide rods 12 are slidably installed on the front and rear ends of the support plate 11. The top of the guide rod 12 is connected to the bottom of the push plate 6.

[0023] The fish fry to be screened are poured into the feeding trough 22, which guides the fry into the screening chamber, improving the convenience of feeding. At the same time, the input end of the water distribution pipe 24 is connected to the water pipe, and the water distribution pipe 24 and the water outlet 25 facilitate the replenishment of water into the screening chamber. The fish bait is placed inside the feed hopper 14, and the servo motor 15 is started to drive the rotating rod 16 to rotate. The rotating rod 16 drives the two spiral blades 17 to rotate, pushing the fish bait forward and backward to the sides and falling into the screening chamber through the feeding hole. As time increases, the left servo motor 15 is turned off, allowing the smallest fish fry to pass through the right end screening mesh plate 4 and swim to the rightmost chamber, speeding up the screening of fry and improving the screening efficiency. When the push plate 6 moves up and down, it drives the guide rod 12 to slide on the support plate 11, guiding and limiting the push plate 6, enhancing the structural strength and improving stability.

During operation, the fish fry to be screened are poured into the feeding trough 22, which guides the fry into the screening chamber. The input end of the water distribution pipe 24 is connected to a water pipe, allowing water to be added to the screening chamber via the water distribution pipe 24 and the water outlet 25. The fry are screened by two screening mesh plates 4. Fish bait is placed inside the feed hopper 14. The servo motor 15 is activated, driving the rotating rod 16 to rotate. The rotating rod 16 drives two spiral blades 17 to rotate, pushing the fish bait forward and backward to the sides, where it falls into the screening chamber through the feeding holes. Over time... Increase, turn off the left servo motor 15, so that the smallest fry can swim through the right end screening mesh plate 4 to the rightmost chamber, speeding up the fry screening. After screening, start the electric telescopic rod 5 to push the crossbeam 7 upward through the push plate 6. The crossbeam 7 drives the sealing cylinder 9 upward through the vertical rod 8, so that the sealing block 10 is moved out of the outlet. This means that the fry do not need to be taken out of the screening box 1 after screening. The fry are directly discharged downward. The fry of different sizes are collected separately through multiple collection boxes 18. Pull the handle 21 to pull the collection box 18 out of the collection chamber for subsequent processing.

[0025] The servo motor 15 of the aquaculture fry screening device of this utility model is purchased from the market.
