Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and specifically relates to a live fish fry stratification and diversion device. Background Technology

[0002] In fish farming, regular selection and counting of fry are essential steps, and also necessary for fry sales and transactions. In traditional aquaculture, farmers enter the pond and use a traditional fish sieve to filter the fry, with the sieve opening slightly above the water surface. They then gently tap the water a few times to remove smaller fry. The remaining fry are transferred to another net cage, completing one selection process. When purchasing fry, the final price is based on the number of fry counted. If the number is too low, the buyer loses money; if the number is too high, the seller loses money. Therefore, accurate counting is crucial for each fry transaction to protect the interests of both parties. However, traditional fry sorting suffers from high labor intensity and low efficiency.

[0003] Therefore, this application provides a live fish fry stratification and diversion device, which aims to solve the problem of fish fry overlap during the process of separating fish and counting fish fry. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0038] like Figures 1-2 As shown, a live fish fry layering and diversion device includes: a fish storage box 1, a cover plate 2, a stepped baffle 3, a flow guide plate 4, and a limiting component 5;

[0039] The fish storage box 1 has a right-angled trapezoidal cross-section along its length. The front side of the fish storage box 1 is a vertical sidewall 101, and the rear side is an inclined sidewall 102. The distance from the inclined sidewall 102 to the vertical sidewall 101 gradually increases from bottom to top. A fish discharge port 104 is provided in the middle of the vertical sidewall 101, and grooves 103 are provided on both sides of the fish discharge port 104.

[0040] The cover plate 2 is disposed on the upper part of the fish storage box 1, and a fish inlet 201 is provided in the middle of the cover plate 2;

[0041] The stepped baffle 3 is vertically slidably disposed in the slide groove 103. A lifting handle 301 is provided on the upper part of the stepped baffle 3, and a transition step 302 is provided on the lower part of the stepped baffle 3.

[0042] The guide plate 4 is disposed at the lower part of the fish outlet 104 and is fixedly connected to the vertical side wall 101. The guide plate 4 is disposed at an angle downward.

[0043] A set of limiting components 5 are respectively provided on both sides of the stepped baffle 3 along its length. The limiting components 5 are fixedly connected to the cover plate 2. The stepped baffle 3 is provided with a limiting rack 6 that cooperates with the limiting components 5.

[0044] With the sloping fish box design, when the fish outlet is opened, the fish fry can swim out of the fish box quickly and smoothly with the help of the slope, which can efficiently achieve the goal of screening fish. For fish fry of different sizes, by flexibly adjusting the size of the stepped fish valve channel, it can ensure that the fish fry pass through in a single layer, avoid the fish fry overlapping, and facilitate the subsequent counting of fish fry.

[0045] The transition step 302, located at the lower part of the stepped baffle 3, serves as a buffer and guide during the fish discharge process. When the fish fry pass through the discharge port 104, the transition step 302 allows the fish fry to flow out of the fish storage tank 1 more smoothly, reducing the impact and damage to the fish fry caused by sudden changes in water flow or drops, and improving the survival rate of the fish fry.

[0046] A set of limiting components 5 is provided on both sides of the stepped baffle 3 along its length, and the limiting components 5 are fixedly connected to the cover plate 2. The stepped baffle 3 is provided with a limiting rack 6 that cooperates with the limiting components 5. This structural design can precisely fix the position of the stepped baffle 3. When the operator adjusts the stepped baffle 3 to a suitable height, the limiting components 5 and the limiting rack 6 cooperate with each other to prevent the stepped baffle 3 from sliding accidentally due to water flow impact or other external forces, ensuring that the size of the fish discharge opening 104 remains stable, thereby ensuring the accuracy and stability of the fish discharge process, and allowing the operator to flexibly adjust the height of the stepped baffle 3.

[0047] like Figures 1-2 As shown, the guide plate 4 is wavy and has an angle of 45° with the vertical sidewall 101.

[0048] The guide plate 4 is located at the lower part of the fish discharge port 104 and is tilted downwards. Its main function is to guide the discharged fish fry to the designated location. The downward tilting design utilizes gravity, allowing the fish fry to slide down the guide plate naturally, reducing the need for additional power, and ensuring the smooth flow of the fish fry during the flow process, preventing the fish fry from accumulating or flowing erratically near the fish discharge port.

[0049] like Figures 1-2 As shown, the fish inlet 201 is provided with connecting plates 202 at its four corners, and the connecting plates 202 are used to cooperate with the conveying pipe.

[0050] The connecting plate 202 provides a stable connection structure between the conveying pipe and the fish inlet 201. By connecting the conveying pipe to the connecting plate 202 (e.g., by bolting, snap-fitting, etc.), it can be ensured that the conveying pipe and the fish inlet 202 fit tightly together. During the fish fry transportation process, even if there is water flow impact or slight shaking of the equipment, the conveying pipe is not easy to separate from the fish inlet 202, ensuring that the fish fry can continuously and stably enter the fish storage tank 1 from the conveying pipe.

[0051] like Figures 3-5As shown, the limiting component 5 includes: a mounting box 501 fixedly connected to the cover plate 2, a movable rod 502 provided in the inner cavity of the mounting box 501, one end of the movable rod 502 extending to the outside of the mounting box 501 and fixedly connected to a limiting tooth block 503, the limiting tooth block 503 cooperating with the limiting toothed rack 6, and the movable rod 502 slidably connected to the mounting box 501;

[0052] The other end of the movable rod 502 is fixedly connected to an extension rod 505. The extension rod 505 extends to the outside of the mounting box 501 and is fixedly connected to an auxiliary handle 510. A threaded ring 506 is slidably sleeved on the outer circumference of the extension rod 505, and the threaded ring 506 is fixedly connected to the mounting box 501.

[0053] A first mating disc 504 is provided on the outer circumference of the movable rod 502, and a second mating disc 507 is provided on the threaded ring 506. A return spring 508 is provided between the first mating disc 504 and the second mating disc 507.

[0054] The limiting tooth block 503 cooperates with the limiting toothed rack 6. When the operator adjusts the stepped baffle 3 to the appropriate height, the limiting tooth block 503 can be embedded in the tooth groove of the limiting toothed rack 6 to achieve precise locking of the position of the stepped baffle 3. This tooth-to-tooth cooperation method can provide greater friction and biting force, effectively preventing the stepped baffle from sliding due to external forces such as water flow impact and equipment vibration, ensuring that the size of the fish discharge outlet 104 remains stable, thereby accurately controlling the discharge flow and size of the fish fry;

[0055] Because the limiting rack 6 has multiple toothed grooves, the limiting block 503 can cooperate with the toothed grooves at different positions, allowing the stepped baffle 3 to be fixed at multiple height positions. This provides convenience for operators to flexibly adjust the size of the fish discharge opening according to different fish fry sizes and fish discharge requirements, enhancing the applicability and flexibility of the device.

[0056] like Figures 4-5 As shown, the outer wall of the threaded ring 506 is provided with threads, the outer wall of the threaded ring 506 is threadedly connected to the mounting box 501, and a friction ring 509 is fixedly connected to the circumferential side wall of the threaded ring 506 outside the mounting box 501.

[0057] By rotating the threaded ring 506, the preload of the return spring 508 can be adjusted. A suitable preload can ensure that the return spring 508 performs the best return effect, so that the limit tooth block 503 can accurately and timely engage or disengage with the limit tooth rack 6, further improving the working performance and stability of the limit assembly.

[0058] like Figure 6As shown, the outer corners of the transition step 302 are all rounded.

[0059] Fish fry are relatively fragile and can easily be injured by collisions when they encounter sharp corners while swimming. The rounded corner design prevents the fish fry from directly colliding with the outer corners of the transition steps 302, reducing the risk of physical damage such as abrasions and scale loss on the fish fry's body surface. This helps to improve the survival rate of the fish fry when passing through the fish discharge port, ensures the health of the fish fry, and reduces the spread of diseases that may be caused by injury. This is of great significance for the subsequent growth of the fish fry and the aquaculture benefits.

[0060] like Figure 7 As shown, in one specific embodiment, the fish discharge port 104 of the fish storage box 1 is matched with the bottom of the inner cavity of the fish storage box 1 to ensure that the fish fry are completely discharged; the vertical side wall 101 is provided with an extension portion downward, the guide plate 4 is fixedly connected to the extension portion, and the upper edge of the guide plate 4 is matched with the lower edge of the fish discharge port 4 to ensure the smooth transport of the fish fry.

[0061] like Figure 8 As shown, in one specific embodiment, a locking bolt 511 is threadedly connected to the mounting box 501 of the limiting component 5. The lower end of the locking bolt 511 extends into the inner cavity of the mounting box 501 and cooperates with the movable rod 502. When the operator needs to fix the movable rod 502 more firmly, it can be locked by the locking bolt 511, which facilitates flexible operation by the operator.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
