Description

A fish fry sorting and dispensing device for fish farming Technical Field

[0001] This utility model relates to the field of fish farming technology, and in particular to a fish fry sorting and dispensing device for fish farming. Background Technology

[0002] Fry stocking is the process of placing young fish fry into artificially raised fishponds. Due to the uneven distribution of fry, fry of different sizes and species cannot be mixed during stocking, as doing so would severely impact survival rates. Therefore, current technology utilizes a stocking device to release fry of different sizes into the rearing pond in stages.

[0003] However, existing release devices have certain shortcomings. For example, existing release devices release fish fry into the breeding pond by tilting, which, due to the lack of buffering, easily results in a large impact force when the fish fry come into contact with the water surface, leading to excessive damage to the fry. Some release devices with buffering structures are also bulky. Therefore, this utility model proposes a fish fry sorting and release device for fish farming to address the shortcomings of existing technologies. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a fish fry sorting and release device for fish farming. After the fish fry exit from the fish outlet pipe, they enter a buffer fish outlet trough at a lower position. After the buffer fish outlet trough slides out, one end can directly approach the water surface, allowing the fish fry to quickly and safely enter the aquaculture pond water after exiting the buffer fish outlet trough. The fish fry will not be separated from the water source for a long time and the problem of impacting the pond water from a height is avoided, making the release of fish fry highly safe.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fish fry sorting and releasing device for fish farming includes a releasing box, fish outlet pipes, and buffer fish outlet troughs. The releasing box has a ramp plate at its lower interior. A fish outlet pipe is located on the side wall of the releasing box at one end of the ramp plate. Multiple sets of fish outlet pipes are provided, each connected to the interior of the releasing box, and each set of fish outlet pipes is movably equipped with a valve plate. The interior of the releasing box below the ramp plate is a hollow structure. A buffer fish outlet trough, adapted to the position of the fish outlet pipes, is slidably installed within the hollow structure. One end of each buffer fish outlet trough extends out of the hollow structure. Adjacent buffer fish outlet troughs are connected by connecting rods. A through groove is provided on the side wall of the releasing box. A pull rod is provided on one side wall of each set of buffer fish outlet troughs, with one end extending from the through groove.

[0007] A further improvement is that: the bottom of the delivery box is equipped with casters at the four corners, and the casters are equipped with brake pads.

[0008] A further improvement is that a push handle is provided on the upper side wall of the feeding box away from the fish outlet pipe.

[0009] A further improvement is that the interior of the buffer fish outlet tank is a sloping structure, and one end of the buffer fish outlet tank has an opening at the top that is compatible with the fish outlet pipe.

[0010] A further improvement is that the release box is equipped with a partition plate inside, which divides the release box into multiple fry zones that are adapted to the number and location of the fish outlet pipes.

[0011] A further improvement is that a sliding groove is provided on one side wall of the top of the delivery box, and a cover plate is slidably installed inside the sliding groove. The cover plate has a hollow mesh structure.

[0012] The beneficial effects of this utility model are as follows: This utility model sets a ramp plate at the bottom inside the feeding box, and sets multiple fish outlet pipes on the side wall of the feeding box at one end of the ramp plate. Then, a buffer fish outlet trough body adapted to the position of the fish outlet pipes is slidably set in the cavity structure inside the feeding box below the ramp plate. The fish fry are fed from the lower fish outlet pipe. After the fish fry come out of the fish outlet pipe, they enter the buffer fish outlet trough body at a lower position. After the buffer fish outlet trough body slides out, one end can directly approach the water surface, so that the fish fry can quickly and safely enter the aquaculture pond water after coming out of the buffer fish outlet trough body. The fish fry will not be separated from the water source for a long time and the problem of impacting the pond water from a high place is avoided, so the safety of fish fry feeding is high.

[0013] The buffer fish tank of this invention can be slidably stored in the cavity structure, making the overall area occupied by the device small. Attached Figure Description

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] Example 1

[0020] As shown in Figures 1-3, this embodiment proposes a fish fry sorting and releasing device for fish farming, including a releasing box 1, a fish outlet pipe 2, and a buffer fish outlet trough 3. The releasing box 1 has a ramp plate 4 at the bottom inside. The fish outlet pipe 2 is provided on the side wall of the releasing box 1 at one end of the ramp plate 4. There are multiple sets of fish outlet pipes 2, and all sets of fish outlet pipes 2 are connected to the inside of the releasing box 1. Each set of fish outlet pipes 2 is movably provided with a valve plate 5. The inside of the releasing box 1 below the ramp plate 4 is a cavity structure. The buffer fish outlet trough 3, which is adapted to the position of the fish outlet pipe 2, is slidably provided in the cavity structure. One end of the buffer fish outlet trough 3 extends out of the cavity structure. Adjacent buffer fish outlet troughs 3 are connected by a connecting rod. The side wall of the releasing box 1 is provided with a through groove 6. One end of the side wall of one set of buffer fish outlet troughs 3 is provided with a pull rod 7, and one end of the pull rod 7 extends out from the through groove 6.

[0021] When using this fish fry sorting and releasing device for fish farming, the fish fry to be released are placed in the releasing box 1. When the entire device moves to the designated releasing position, the buffer fish release trough 3 is first slid out, so that one end of the buffer fish release trough 3 is above the water surface of the breeding pond. Then, by opening the valve plate 5 on the fish release pipe 2, the fish fry in the releasing box 1 enter the buffer fish release trough 3 through the fish release pipe 2, and are buffered and guided into the breeding pond by the buffer fish release trough 3. After the fish fry release is completed, the buffer fish release trough 3 is slid back into its hollow structure.

[0022] The release box 1 is equipped with casters 8 at its four corners, and each caster 8 has a brake pad. A push handle 9 is located on the upper side wall of the release box 1 away from the fish outlet pipe 2. When the release box 1 moves, the push handle 9 is manually pushed to move the release box 1 under the action of the casters 8. During fish fry release operations, the casters 8 are locked by pressing the brake pad.

[0023] The buffer fish outlet tank 3 has a sloping interior, and one end of the buffer fish outlet tank 3 has an opening 10 that matches the fish outlet pipe 2. The fish fry coming out of the fish outlet pipe 2 enter the buffer fish outlet tank 3 through the opening 10.

[0024] This invention features a ramp plate 4 installed at the bottom of the feeding box 1, with multiple fish outlet pipes 2 on the side wall of the feeding box 1 at one end of the ramp plate 4. A buffer fish outlet trough 3, adapted to the position of the fish outlet pipes 2, is slidably installed within the cavity structure inside the feeding box 1 below the ramp plate 4. Fish fry are released from the lower fish outlet pipe 2, and after exiting the pipe 2, the fry enter the buffer fish outlet trough 3 at an even lower position. One end of the buffer fish outlet trough 3 can slide directly close to the water surface, allowing the fry to quickly and safely enter the aquaculture pond after exiting the trough 3. This prevents the fry from being out of the water source for extended periods and avoids the problem of impacting the water from a height, resulting in high safety during fry release. Furthermore, the buffer fish outlet trough 3 can be slidably stored within the cavity structure, minimizing the overall footprint of the device.

[0025] Example 2

[0026] As shown in Figures 1-3, this embodiment proposes a fish fry sorting and releasing device for fish farming, including a releasing box 1, a fish outlet pipe 2, and a buffer fish outlet trough 3. The releasing box 1 has a ramp plate 4 at the bottom inside. The fish outlet pipe 2 is provided on the side wall of the releasing box 1 at one end of the ramp plate 4. There are multiple sets of fish outlet pipes 2, and all sets of fish outlet pipes 2 are connected to the inside of the releasing box 1. Each set of fish outlet pipes 2 is movably provided with a valve plate 5. The inside of the releasing box 1 below the ramp plate 4 is a cavity structure. The buffer fish outlet trough 3, which is adapted to the position of the fish outlet pipe 2, is slidably provided in the cavity structure. One end of the buffer fish outlet trough 3 extends out of the cavity structure. Adjacent buffer fish outlet troughs 3 are connected by a connecting rod. The side wall of the releasing box 1 is provided with a through groove 6. One end of the side wall of one set of buffer fish outlet troughs 3 is provided with a pull rod 7, and one end of the pull rod 7 extends out from the through groove 6.

[0027] The feeding box 1 is equipped with a partition plate 11, which divides the feeding box 1 into multiple fry zones adapted to the number and position of the fish outlet pipes 2. This invention utilizes the partition plate 11 to divide the feeding box 1 into multiple fry zones adapted to the number and position of the fish outlet pipes 2, allowing for the temporary storage of fry of different sizes in each zone. Then, by opening the valve plate 5 of the corresponding fish outlet pipe 2, fry of different sizes can be released into the corresponding breeding pond. The multiple fry zones of this invention can also be used to temporarily store fry of the same size before release.

[0028] The top side wall of the feeding box 1 is provided with a sliding groove, and a cover plate 12 is slidably installed inside the sliding groove. The cover plate 12 has a hollow mesh structure. By setting the cover plate 12, this utility model can prevent the fish fry from being shaken out of the feeding box 1 due to water sloshing during the movement of the device. The hollow mesh structure of the cover plate 12 can effectively allow for ventilation and prevent the fish fry from suffocating.
