A number of large-scale deep-sea aquaculture equipment have been launched and put into operation, such as "Sea Granary No. 1", "Hengyi No. 1", and "Deep Blue No. 2". Deep-sea water is rich in nutrients, has sufficient water exchange, and excellent water quality, making it a natural marine pasture. It is more suitable for raising valuable fish species with higher economic added value, such as salmon, large yellow croaker, and amberjack.

[0023] This invention provides a device for feeding frozen miscellaneous fish. Figures 1 to 6 This is an embodiment of the feeding device for frozen miscellaneous fish provided by the present invention.

[0024] Deep-sea aquaculture requires feeding fresh, frozen miscellaneous fish, which involves multiple processes such as thawing and chopping. Existing equipment typically separates thawing and chopping before transferring the feed to the feeding device, resulting in frequent manual operations and low efficiency. For example, thawed feed needs to be manually transported to the chopping equipment, and the chopped feed is then transferred to the feeding pipeline, which involves high labor intensity and time costs.

[0025] Please refer to the following: Figures 1 to 2 The chilled miscellaneous fish feed feeding device 100 includes a thawing box 1, a chopping structure 5, and a conveying device 6. The thawing box 1 forms multiple thawing troughs 3, each extending in a first direction. A water supply tank 2 is located at the top of the thawing box 1, connected to a water inlet pipe, and has multiple water inlets 9, each corresponding to one of the thawing troughs 3. Each thawing trough 3 has movable baffles 4 on both sides in the first direction, with first drainage grilles 8 at the top and bottom of the movable baffles 4. Drainage channels 11 are located at both ends of the thawing box 1, with second drainage grilles 10 at the top of each channel 11 and a drainage pipe at the bottom. The bottom plate of the drainage channel 11 is inclined in the second direction. The chopping structure 5 includes a box body 501, a feeding pipe 504, a discharge pipe 503, and a cutting assembly 502. The box body 501 is located on one side of the thawing box 1 in the second direction. The box body 501 forms a chopping chamber with an opening at the top. The cutting assembly 502 includes multiple cutters 5021, which are located inside the chopping chamber for chopping the thawed feed. The discharge pipe 503 is located at the bottom of the box body 501. One end of the feeding pipe 504 is located at the bottom of the discharge pipe 503, and the other end is located towards the breeding area. One end of the conveying device 6 is located on one side of the thawing box 1 in the second direction, and the other end is located at the opening of the box body 501 for transporting the thawed feed into the box body 501.

[0026] The thawing tank 3 is a container used to thaw frozen fresh miscellaneous fish. It can be a long, narrow tank structure, with multiple tanks arranged side-by-side to improve thawing efficiency. The movable baffle 4 has first drainage grilles 8 at both the top and bottom. When the top first drainage grille 8 starts draining, it indicates that the bottom first drainage grille 8 is blocked and needs to be cleaned promptly. The first drainage grille 8 is a perforated plate, which can be made of metal or plastic, and is used to discharge wastewater generated during thawing. The cutter 5021 is a rotary cutter, which can be made of stainless steel and is driven by a motor to crush the feed. The conveying device 6 is a material conveying equipment, which can be a belt conveyor with baffles on its surface to prevent feed from slipping.

[0027] Fresh, frozen fish are placed in the thawing tank 3, and water is injected into the water tank 2 through the inlet pipe to gradually thaw the feed. During the thawing process, the movable baffle 4 adjusts the water level, and wastewater enters the drainage trough 11 through the first drainage grille 8 and the second drainage grille 10 at the top of the drainage trough 11, and is finally discharged through the drain pipe on the drainage trough 11. After thawing, the conveying device 6 transports the feed to the opening at the top of the chopping chamber, where the cutter 5021 rotates to chop the feed. The chopped feed falls into the feeding pipe 504 through the feed pipe 503 and is then transported to the aquaculture area by a water pump. The thawing tank 1 and the chopping structure 5 are connected by the conveying device 6 to achieve continuous automated operation of the thawing and chopping processes.

[0028] Therefore, the thawing box 1 has multiple thawing slots 3, each extending in a first direction. A water supply tank 2 is located at the top of the thawing box 1, connected to a water inlet pipe, and has multiple water inlets 9. Each water inlet 9 corresponds to one of the thawing slots 3. Movable baffles 4 are provided on both sides of each thawing slot 3 in the first direction. First drainage grilles 8 are provided at the top and bottom of each movable baffle 4. Drainage channels 11 are located at both ends of the thawing box 1. Second drainage grilles 10 are provided at the top of each drainage channel 11, and a drainage pipe is provided at the bottom of each drainage channel 11. The bottom plate of each drainage channel 11 is inclined in the second direction. The chopping structure 5 includes a box body 501, a feeding pipe 504, a discharge pipe 503, and... The feed cutting assembly 502 includes a box 501 located on one side of the thawing box 1 in the second direction. The box 501 has a chopping chamber with an opening at the top. The feed cutting assembly 502 includes multiple cutters 5021, which are located inside the chopping chamber and used to chop the thawed feed. A feed pipe 503 is located at the bottom of the box 501. One end of a feeding pipe 504 is located at the bottom of the feed pipe 503, and the other end is located towards the breeding area. A conveying device 6 is located on one side of the thawing box 1 in the second direction, and the other end is located at the opening of the box 501, used to transport the thawed feed into the box 501. Controllable drainage is achieved through the cooperation of a movable baffle 4 and a first drainage grid 8.

[0029] In order to effectively reduce the mechanical wear of the chopping structure 5, avoid the cutter 5021 from getting stuck or damaged due to large pieces of feed, and at the same time ensure that the size of the feed entering the feeding stage is not too large.

[0030] Specifically, in an embodiment of the present invention, the thawing box 1 is provided with a sieving box 7 on one side in the second direction. The sieving box 7 is located on the upper side of the transmission device, and the bottom of the sieving box 7 is provided with a plurality of sieving ports.

[0031] The screening box 7 is a container used for the initial sorting of thawed feed. It can be implemented using a combination of a metal frame and a mesh structure. The screening opening at the bottom allows feed of the required size to pass through, while blocking feed that is not fully thawed or is too large. The design of the screening box 7, located above the transmission device, ensures that the thawed feed is screened before entering the conveyor 6, preventing equipment blockage caused by large pieces of feed in the subsequent chopping process.

[0032] After thawing, the feed is transferred from the thawing tank 3 to the screening box 7 and falls naturally under gravity. The screening opening at the bottom of the screening box 7 is set according to the target feed particle size; for example, the screening opening width can be set to 50 mm to 80 mm. Feed that meets the size requirements falls through the screening opening into the conveyor device 6 below, while larger pieces of feed that do not pass through remain in the screening box 7 for further manual or mechanical processing. The vertical relationship between the screening box 7 and the conveyor device 6 ensures that the screened feed enters the conveying process directly without additional transfer steps.

[0033] Please refer to the following: Figures 3 to 6 The chopping chamber is provided with multiple drive components 505. Each drive component 505 includes a drive motor 5053, two first rotating rods 5051, two first gears 5052, two first sprockets, and a first chain 5054. The drive motor 5053 is mounted on the outer wall of the housing 501. The two first rotating rods 5051 are rotatably mounted in the chopping chamber. The two first gears 5052 are respectively mounted on each of the first rotating rods 5051 and mesh with each other. One of the two first sprockets is located on the output shaft of the drive motor 5053, and the other first sprocket is located on the first rotating rod 5051. The first chain 5054 is located on the two first sprockets. Each cutter 5021 is respectively located on the two first rotating rods 5051 so that when the first rotating rods 5051 rotate, they drive the cutters 5021 to rotate and chop the feed.

[0034] The drive motor 5053 is a device that provides power, specifically a geared motor, which transmits rotational power through its output shaft. The first rotating rod 5051 is the rotating shaft that supports the cutter 5021, specifically a hollow stainless steel shaft, used to mount the cutter 5021 and transmit rotational motion. The first gear 5052 is a meshing transmission component, specifically a helical gear, which ensures the two first rotating rods 5051 rotate synchronously in opposite directions through meshing. The first sprocket is a transmission component that cooperates with the chain, specifically a double-row sprocket, connecting the drive motor 5053 and the first rotating rods 5051 via the chain to transmit power. The first chain 5054 is a transmission component connecting the sprocket, specifically a roller chain, used to transmit the power of the drive motor 5053 to the first rotating rods 5051.

[0035] A drive motor 5053 drives one of the first sprockets to rotate via its output shaft. A first chain 5054 transmits power to the other first sprocket, causing the first rotating rod 5051 to rotate. Two first gears 5052 mesh with each other, ensuring that the two first rotating rods 5051 rotate synchronously in opposite directions. A cutter 5021 is fixed to the surface of the first rotating rod 5051 and cuts the feed falling into the chopping chamber as the rod rotates. Because the cutters 5021 of the two first rotating rods 5051 rotate in opposite directions, the feed is cut bidirectionally within the chopping chamber, thereby improving chopping efficiency and uniformity.

[0036] Furthermore, the chopping chamber is also provided with a plurality of distribution structures 506, and the distribution structures 506 are located below the drive assembly 505. The distribution structure 506 includes two turntables 5063 and a plurality of dividing plates 5066. The two turntables 5063 are rotatably disposed in the chopping chamber, and the plurality of dividing plates 5066 are disposed on the outer periphery of each turntable 5063 and are spaced apart along the circumference of the turntables 5063.

[0037] Turntable 5063 refers to a disc structure used for rotating and distributing feed. It can be made of metal or plastic and has multiple dividing plates 5066 on its surface to form spaces for accommodating feed. Dividing plates 5066 are plate-like structures perpendicular to the surface of turntable 5063. They can be welded or bolted to the outer periphery of turntable 5063 and are used to divide the feed into different areas during rotation.

[0038] When the drive assembly 505 drives the cutter 5021 to rotate and chop the feed via the first rotating rod 5051, the second sprocket 5065 on the first rotating rod 5051 transmits power to the second rotating rod 5064 via a chain. The second gear 5062 at the end of the second rotating rod 5064 meshes with each other, causing the two turntables 5063 to rotate in opposite directions. During rotation, the dividing plate 5066 on the turntable 5063 evenly divides the falling feed and pushes it to the area of ​​the cutter 5021, preventing feed from accumulating in the same position in the chopping chamber. The relative motion between the turntable 5063 and the cutter 5021 continuously disperses and chops the feed, improving chopping efficiency.

[0039] Furthermore, the distribution structure 506 also includes two second rotating rods 5064, two second sprockets 5065, and two second gears 5062. The two second rotating rods 5064 are rotatably mounted in the chopping chamber. One of the two second sprockets 5065 is disposed on the first rotating rod 5051, and the other second sprocket 5065 is disposed on one of the second rotating rods 5064. The second chain 5061 is disposed on the two second sprockets 5065. The two second gears 5062 mesh with each other and are respectively mounted on the two second rotating rods 5064. The two turntables 5063 are respectively mounted on the two rotating rods.

[0040] The second sprocket 5065 and chain transmit the rotational power of the first rotating rod 5051 to the second rotating rod 5064. Two second gears 5062 mesh with each other, causing the two second rotating rods 5064 to rotate synchronously in opposite directions. As the turntable 5063 rotates with the second rotating rods 5064, the dividing plate 5066 pushes the chopped feed circumferentially towards the lower feed pipe 503, preventing feed accumulation at the bottom of the chopping chamber. The rotational speed of the turntable 5063 can be adjusted via the sprocket gear ratio; for example, a sprocket with a specific gear ratio can achieve constant speed transmission, or a sprocket with a specific gear ratio can achieve speed reduction transmission.

[0041] To address the problem of discontinuous feeding caused by chopped feed remaining in the cavity, specifically, in the embodiments of the present invention, the feed is ensured to quickly enter the feed pipe 503 and be transported to the breeding area, reducing the need for manual intervention and improving the automation level of the feeding process. The bottom wall of the chopping cavity is inclined toward the opening of the feed pipe 503.

[0042] With the bottom wall of the chopping chamber inclined, the feed naturally moves towards the inlet of the feed pipe 503 during the chopping process, without the need for additional power or mechanical assistance. When the cutter 5021 rotates and chops the feed, the shredded material falls directly onto the inclined bottom wall surface and slides into the feed pipe 503 under the influence of gravity. This structure simplifies the feed feeding process from chopping to delivery and reduces the possibility of residual feed in the chopping chamber.

[0043] The invention also aims to achieve simultaneous operation of chopping and equipment cleaning, effectively preventing blade wear or bacterial contamination caused by feed residue, and improving chopping efficiency and equipment hygiene.

[0044] Specifically, in an embodiment of the present invention, a plurality of high-pressure water pipes 507 are connected to the housing 501, and the outlet of the high-pressure water pipes 507 is provided with a plurality of nozzles located in the chopping chamber.

[0045] The 507 high-pressure water pipe refers to a pipe that connects to an external water source and has a pressurization function. It can be made of stainless steel or pressure-resistant plastic pipe. Its function is to assist in chopping feed and rinsing off residues with high-pressure water flow. The nozzle refers to a water outlet structure with a specific orifice diameter. It can be made of fan-shaped or conical nozzle. Its function is to disperse the high-pressure water flow into multiple impact streams to cover the working area of ​​the chopping chamber.

[0046] A high-pressure water pipe 507 is installed on the side wall or top of the housing 501, with the end of the pipe extending into the chopping chamber and fitted with nozzles. When the cutter 5021 rotates and chops the feed, the high-pressure water flow creates an impact force through the nozzles. This accelerates the dispersion of feed fragments, preventing the cutter 5021 from sticking to the feed, and also washes the walls of the chopping chamber and the surface of the cutter 5021, preventing debris accumulation. For example, the nozzles can be arranged in layers along the height of the chopping chamber. The upper nozzles are aimed at the working area of ​​the cutter 5021 to clean the cutter 5021 and prevent sticking; the middle nozzles are aimed at the feed distribution area to clean the dividing plate 5066; and the lower nozzles are aimed at the inclined surface at the bottom of the chamber to clean the feed pipe 503. As the water flows into the feed pipe 503 along the inclined surface, it carries feed fragments, preventing blockage.

[0047] To achieve fully automated feed delivery from the shredding structure 5 to the breeding area, reduce the need for manual intervention, and avoid pipeline blockage, the feeding pipe 504 is specifically connected to a water pump.

[0048] A water pump is a fluid transport device that provides power to the feeding pipe 504. Specifically, a centrifugal pump or a submersible pump can be used. After the chopped feed falls into the feeding pipe 504 through the discharge pipe 503, the water pump, once started, pushes the feed from the outlet end of the discharge pipe 503 to the outlet end of the feeding pipe 504 via water flow. Finally, the feed is evenly distributed to the aquaculture area through the opening at the end of the feeding pipe 504. The flow rate and pressure of the water pump can be adjusted according to the viscosity of the feed and the feeding distance, for example, by adjusting the pump speed through a frequency converter to adapt to different operating conditions.

[0049] In order to achieve the classified thawing of fresh miscellaneous fish, avoid interference between feeds of different sizes, and improve thawing efficiency; at the same time, by controlling drainage and temperature parameters in zones, reducing manual sorting operations, and adapting to the batch processing needs of diversified feeds in deep-sea aquaculture scenarios, the conveyor belt of the conveyor device 6 is specifically equipped with multiple baffles.

[0050] The baffle extends along the length of the thawing tank 3, with its top flush with the opening of the tank and its bottom providing a drainage channel between it and the bottom wall of the tank 3. The thawing zones on either side of the baffle can be used to thaw different types or sizes of frozen miscellaneous fish; for example, one side can be used to thaw larger fish, while the other side can be used to thaw smaller pieces of fish. The drainage speed of each thawing zone's corresponding drain pipe can be independently controlled, and the opening and closing state of the movable baffle 4 can also be adjusted according to the needs of each thawing zone.

[0051] In some specific embodiments, the surface of the baffle may be provided with a guide channel to guide the thawing water flow to the first drainage grid 8; the baffle may also be designed as a detachable structure, for example, fixed by buckles or bolts, so as to facilitate the adjustment of the number and size of the thawing zone according to the type of feed.

[0052] In order to improve the flexibility and efficiency of the thawing process, adapt to the zoning requirements of different types or specifications of feed, avoid uneven chopping caused by feed mixing, and reduce the equipment footprint and operational complexity, specifically, the thawing box 1 is equipped with a baffle to divide the thawing tank 3 into two thawing zones.

[0053] A baffle extends along the length of the thawing tank 3 and is fixed in the middle of the tank, dividing the originally single thawing tank 3 into two symmetrical or asymmetrical thawing zones. During operation, for example, large and small miscellaneous fish can be placed into different thawing zones, or different thawing parameters can be set for different thawing zones. During thawing, the water supply tank 2 simultaneously injects water into both thawing zones through the water supply port 9. The water flows through the first drainage grille 8 on the movable baffle 4 and the second drainage grille 10 on the drainage trough 11, and is finally discharged through the drain pipe on the drainage trough 11. The presence of the baffle ensures that the water flow in the two thawing zones does not interfere with each other, and the thawed feed can be conveyed to the chopping structure 5 separately via the conveyor device 6.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
