Description

Technical Field

[0001] This invention relates to the field of aquaculture feeding equipment technology, specifically a multi-scenario, all-area centrifugal rotary feed throwing device. Background Technology

[0002] In large-scale, standardized aquaculture ponds, feeding equipment is a core component for ensuring the healthy growth of fish and shrimp, increasing aquaculture productivity, and reducing aquaculture costs. Currently, most conventional pond feeders on the market are fixed-mounted structures on the pond bank, relying on a built-in centrifugal feeding mechanism to distribute feed in a fan-shaped pattern. However, long-term practical application in aquaculture has revealed the following common problems with existing bank-mounted feeders: Firstly, the feeding coverage is limited, resulting in low feeding uniformity. Existing shore-based feeders are limited by their installation location, enabling only single-sided fan-shaped feeding operations. The feeding range is fixed and limited, failing to achieve comprehensive, dead-angle-free coverage of the pond water. For large ponds or aquaculture sheds, the central and offshore areas cannot be effectively covered, leading to concentrated feeding areas for fish and shrimp. This results in excessive feed accumulation and eutrophication near the shore, while fish and shrimp in the offshore areas do not feed sufficiently, causing uneven growth of fish and shrimp in the pond or aquaculture shed, and a decrease in overall aquaculture yield.

[0003] Secondly, the equipment investment cost is high and the operation and maintenance are complicated. In order to make up for the lack of coverage of feeding on one side, large-scale ponds or breeding sheds must deploy multiple feeding machines on both sides and four corners. The feeding of the whole area is ensured through the coordinated operation of multiple devices, which greatly increases the cost of equipment procurement, circuit wiring and equipment maintenance.

[0004] Third, they have poor adaptability and cannot be adapted to different aquaculture conditions. Existing fixed feeders have fixed throwing angles, throwing ranges, and throwing flow rates, which cannot be flexibly adjusted according to the feeding needs of fish and shrimp fry at different growth stages, as well as shallow water, deep water, and different density aquaculture scenarios. This easily leads to problems such as throwing too far and wasting feed in the seedling stage, insufficient throwing range, and uneven feeding. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a multi-scenario, all-area centrifugal rotary feed throwing device. Through the design of all-area centrifugal rotary feeding, it realizes all-round feeding without dead angles in the center of the water body in ponds or breeding sheds, reduces the number of equipment inputs, improves the feeding uniformity and equipment adaptability, and reduces breeding costs and equipment failure rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-scenario, all-area centrifugal rotary feed throwing device includes a centrifugal rotary throwing assembly, which is directly fixed to the middle aisle of the breeding shed, or the centrifugal rotary throwing assembly is fixed to a floating body floating on the surface of a pond via a bracket; the centrifugal rotary throwing assembly includes a main housing fixed to the bracket, a feeder with a feed pipe on the side fixed above the main housing, a thrower with a throwing pipe on the side rotating above the main housing and communicating vertically with the feeder, and a motor for driving the thrower to rotate fixed inside the main housing.

[0007] By adopting the above solution, this device can make full use of the space in the aquaculture shed, avoid occupying the aquaculture water area, and facilitate equipment installation, inspection and daily maintenance, reducing interference with aquaculture operations. It can also be placed directly in the center of the pond water, and with the coaxial center of gravity design, it ensures that the equipment floats stably on the water without tilting or overturning. Its application scenarios are wider, and it can be flexibly selected according to different aquaculture sheds, ponds and other aquaculture scenarios, improving the equipment's versatility and adaptability, and meeting diverse aquaculture feeding needs. The feed thrower is driven by a motor to rotate at high speed, and centrifugal force is used to achieve 360° all-area feeding. Compared with the traditional single-sided fan-shaped feeding, it greatly expands the feeding coverage area, realizing feeding in ponds or aquaculture sheds without dead corners. A single device can cover the entire pond or aquaculture shed water body, eliminating the need for multiple devices and greatly reducing equipment procurement and operation and maintenance costs.

[0008] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, the feed pipe delivers feed in real time through a conveying pipe on shore. The motor is controlled and powered in real time via a control switch and power supply on shore, either through a central aisle or on shore. The feed line from the conveying pipe, the control line from the control switch, and the power supply line are all integrated into a single unit and fed to the centrifugal rotary throwing assembly. This centralized feed, power, and control mode, achieved through a central aisle or on shore, integrates the feed line, control line, and power line, eliminating problems such as messy, tangled, water-damaged, and aging wiring. This improves the safety and stability of the equipment during water operation, simplifies the wiring structure, reduces the probability of line failure, and facilitates future maintenance.

[0009] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, the throwing pipe has three locations, which are evenly distributed circumferentially around the thrower. Working in conjunction with the rotating operation of the thrower, it enables simultaneous centrifugal throwing through multiple channels, resulting in uniform feed output and good dispersion. This avoids the problems of concentrated output and localized material accumulation that exist with single-pipe throwing, further improving the uniformity of feeding throughout the pond and increasing the throughput per feeding cycle.

[0010] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, a discharge chamber connected to the feed pipe is opened inside the feeder, and an upper feeding chamber connected to the throwing pipe is opened inside the thrower, wherein the upper feeding chamber and the discharge chamber are connected. The upper and lower connected discharge chamber and upper feeding chamber form a closed feed conveying channel, and the feed is conveyed in a sealed manner throughout the process. This effectively avoids the problems of feed getting damp, clumping, and clogging caused by water waves and splashes entering the equipment, ensuring smooth feed conveying, improving the continuous operation capability of the equipment, and reducing feed blockage failures.

[0011] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, three guide partitions are connected inside the feeding chamber to separate the chambers and guide the feed to the throwing pipes. The guide partitions divide the feeding chamber into three independent feeding channels, which correspond one-to-one with the three throwing pipes. This can accurately guide the falling feed to each throwing pipe, preventing the feed from running around, piling up, or being unevenly distributed in the chamber. It ensures that the feed output from the three throwing pipes is uniform and consistent, eliminates localized feed shortages and accumulation, and further improves the uniformity of the all-area throwing.

[0012] As a preferred implementation of a multi-scenario, all-area centrifugal rotary feed throwing device, each throwing pipe has an extended throwing pipe coaxially connected to its outlet via a docking valve. The extended throwing pipe extends the feed throwing arm, increases the initial centrifugal throwing velocity, effectively increases the throwing range, and expands the equipment's coverage radius, making it suitable for feeding large-area ponds. At the same time, the docking valve structure facilitates the quick disassembly, replacement, and cleaning of the extended throwing pipe, improving the convenience of equipment maintenance.

[0013] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, each docking valve is inclined and bent upwards, causing the extended throwing tube to extend upwards at an angle of 5-20° with the horizontal plane. This oblique throwing trajectory extends the feed's flight distance in the air, further increasing the throwing range and coverage area, while avoiding the problem of central accumulation caused by feed falling vertically at close range. This angle range is suitable for most pond or aquaculture shed conditions, balancing throwing distance and uniformity, making it highly practical.

[0014] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, an avoidance groove is provided above the extended throwing pipe away from the docking valve. A flared-mouth flip-over sleeve that completely covers the avoidance groove is rotatably installed above the extended throwing pipe. An inner sliding groove extending axially is provided below the extended throwing pipe. An outer sliding groove that is inclined and works with the inner sliding groove is provided on both sides of the flared-mouth flip-over sleeve. A sliding rod that can slide in the groove passes through both the outer and inner sliding grooves. Nuts that lock the sliding rod are threaded at both ends. The relative position of the extended throwing pipe and the flared-mouth flip-over sleeve can be changed by moving the sliding rod, thereby changing the size of the final throwing outlet. With its adjustable structure consisting of a chute and a slide bar, the opening and closing size of the feeding outlet can be flexibly adjusted, thereby precisely controlling the discharge flow rate and the dispersion of the material. A larger outlet allows for high-flow feeding, suitable for high-density aquaculture of fish and shrimp; a smaller outlet allows for low-flow, fine feeding, suitable for fish and shrimp fry farming. This multi-purpose machine significantly improves the adaptability of the equipment to different operating conditions.

[0015] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, an inner lug is connected to the upper part of the extended throwing pipe near the docking valve, and an outer lug is connected to the upper part of the flared-mouth flipping sleeve near the docking valve. The inner and outer lugs are movably hinged together. The flipping angle of the flared-mouth flipping sleeve, based on the outer lug, ranges from 0 to 35°. This hinged flipping structure, combined with the 0-35° adjustable flipping angle, allows for changes in the opening and closing arc of the throwing outlet and the throwing diffusion angle. A larger angle results in a wider feed spreading range, enabling flexible adjustment of the throwing width according to pond size and stocking density, further enhancing the equipment's versatility and adapting to the feeding needs of ponds of different sizes.

[0016] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, the entire linear array of the inner chute has multiple limiting grooves that can limit the movement of the sliding rod, wherein the cross-sectional shape of the limiting groove is triangular. The triangular limiting grooves of the linear array can precisely lock the sliding rod after sliding adjustment, preventing the sliding rod from shifting or the sleeve from loosening during high-speed rotation and vibration of the equipment, ensuring the stability of the throwing outlet adjustment size, ensuring that the throwing flow rate and throwing range remain constant during long-term operation, and improving the stability and reliability of equipment operation.

[0017] As a preferred embodiment of a multi-scenario, all-area centrifugal rotary feed throwing device, the centrifugal rotary feed throwing assembly is fixed to the central aisle of the aquaculture shed via a bracket. This fully utilizes the space of the aquaculture shed, avoids occupying the aquaculture water area, and facilitates equipment installation, inspection, and daily maintenance, reducing interference with aquaculture operations. Alternatively, the centrifugal rotary feed throwing assembly can be fixed to a floating body on the pond surface via a bracket. This adaptable to aquaculture water bodies of different sizes and depths, offering flexible installation without being limited by the pond structure and a wider range of applications. The centrifugal rotary feed throwing assembly and the floating body are both located on the same vertical line, significantly improving overall stability in the floating state and effectively preventing tilting, overturning, or shaking due to centrifugal force during operation. This ensures uniform feeding, reliable operation, and extends the equipment's service life. Both installation methods can be flexibly selected according to different aquaculture scenarios such as aquaculture sheds and ponds, improving the equipment's versatility and adaptability to meet diverse aquaculture feeding needs.

[0018] The beneficial effects of this invention are: 1. Multi-scenario full-area coverage, significantly improving feeding uniformity: It can be flexibly selected according to different breeding scenarios such as breeding sheds and ponds, improving the equipment's versatility and adaptability, meeting diverse breeding feeding needs, and with a 360° centrifugal rotating throwing structure, a single device can achieve all-round, no-dead-angle feeding in the pond, so that fish and shrimp in the pond or breeding shed can eat evenly, effectively improving the uniformity of fish and shrimp growth size and increasing the overall breeding yield; 2. Reduce costs and increase efficiency, reduce equipment investment and energy consumption: A single piece of equipment can replace multiple traditional pieces of equipment, significantly reducing equipment procurement, wiring and installation costs; at the same time, the energy consumption of a single piece of equipment is lower, which can significantly reduce electricity costs and equipment operation and maintenance costs in long-term farming, thereby improving the economic benefits of farming. 3. Adjustable parameters and strong adaptability to working conditions: By adjusting the size of the discharge outlet and the flip-out flared tube structure, the discharge flow rate, discharge range and discharge diffusion range can be flexibly changed, which can adapt to different growth stages of fish fry and shrimp fry, as well as the feeding needs of ponds of different sizes and different breeding densities. It is a multi-purpose machine with strong versatility, which solves the defects of fixed parameters and poor adaptability of traditional equipment. 4. Anti-blocking and damage prevention, high operational stability: The closed upper and lower connected material chamber + independent material guide baffle structure realizes precise feed diversion and effectively avoids feed accumulation, clumping and blockage; the integrated circuit layout eliminates the problems of messy circuits, water aging, tangling and damage, while the triangular limit groove ensures that the adjustment structure does not loosen during long-term operation, greatly reducing the equipment failure rate and strong continuous operation capability. 5. Good feeding effect and high feed utilization: The tilting and adjustable throwing structure extends the feeding throwing distance and expands the diffusion range, avoiding water pollution and feed waste caused by concentrated feed accumulation. It is precisely adapted to the feeding patterns of fish and shrimp, greatly improves feed utilization, reduces residual feed pollution, and improves the pond water environment.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, as Figures 1 to 5 As shown, a multi-scenario, all-area centrifugal rotary feed throwing device is provided, mainly used for feeding shrimp in aquaculture sheds. Specifically, it includes a centrifugal rotary feed throwing assembly 3, which is directly fixed on the middle aisle of the aquaculture shed. The centrifugal rotary feed throwing assembly 3 includes a main housing 4 fixed to a bracket 2, a feeder 5 with a feed pipe 6 on the side fixed above the main housing 4, and a feeder 7 with a throwing pipe 8 on the side that is rotatably connected to the feeder 5 above the main housing 4. A motor 9 that drives the feeder 7 to rotate is fixed inside the main housing 4. This device can make full use of the space in the aquaculture shed, avoid occupying the aquaculture water area, and facilitate equipment installation, inspection and daily maintenance, reducing interference with aquaculture operations. The motor 9 drives the feed thrower 7 to rotate at high speed, using centrifugal force to achieve 360° all-area feeding. Compared with the traditional single-sided fan-shaped feeding, it greatly expands the feeding coverage area, realizing feeding without dead corners in the aquaculture shed. A single device can cover the water body of the aquaculture shed, eliminating the need for multiple devices and greatly reducing equipment purchase and operation and maintenance costs.

[0024] Continue as Figures 1 to 5 As shown, the feed pipe 6 conveys material in real time through the conveying pipe in the central aisle. The motor 9 is controlled and powered in real time by a control switch and a power supply on shore. The material feed line of the conveying pipe, the control line of the control switch, and the power supply line are all integrated into one unit and conveyed to the centrifugal rotary throwing assembly 3. The centralized material supply, power supply, and material control mode in the central aisle avoids the problems of unstable center of gravity and floating imbalance caused by the material hopper on the water. At the same time, the material feed line, control line, and power supply line are integrated and laid out in one unit, eliminating the problems of messy, tangled, water-soaked, aging, and damaged lines, improving the safety and stability of the equipment on water, simplifying the wiring structure, reducing the probability of line failure, and facilitating later inspection and maintenance.

[0025] like Figures 2 to 5 As shown, there are three feeding pipes 8, which are evenly distributed circumferentially about the feeder 7. Working in conjunction with the rotating feeder 7, they enable multi-channel synchronous centrifugal feeding, resulting in uniform and well-dispersed feed output. This avoids the problems of concentrated output and localized pile-up that exist with single-pipe feeding, further improving the uniformity of feeding in the breeding shed and increasing the throughput of a single feeding cycle.

[0026] like Figures 6 to 7 As shown, a discharge chamber 10 connected to the feed pipe 6 is provided inside the feeder 5, and an upper discharge chamber 11 connected to the discharge pipe 8 is provided inside the thrower 7. The upper discharge chamber 11 is connected to the discharge chamber 10. The upper and lower discharge chambers 10 and 11 form a closed feed conveying channel, ensuring that the feed is conveyed in a sealed manner throughout the process. This effectively avoids the problems of feed getting damp, clumping, and clogging caused by water waves and splashes entering the equipment, ensuring smooth feed conveying, improving the continuous operation capability of the equipment, and reducing feed blockage failures.

[0027] like Figure 7 As shown, there are three guide partitions 12 inside the feeding chamber 11 that separate the chambers and guide the feed to the location of the throwing pipes 8. The guide partitions 12 divide the feeding chamber 11 into three independent feeding channels, which correspond one-to-one with the three throwing pipes 8. This can accurately guide the falling feed to each throwing pipe 8, avoid the feed from running around, piling up, or being unevenly distributed in the chamber, ensure that the output of the three throwing pipes 8 is uniform, eliminate local shortages and accumulations, and further improve the uniformity of feeding throughout the entire area.

[0028] like Figures 2 to 5 As shown, each feed throwing pipe 8 has an extended feed throwing pipe 14 coaxially connected to its outlet via a docking valve 13. The extended feed throwing pipe 14 extends the feed throwing arm, increases the initial velocity of centrifugal throwing, effectively increases the throwing range, and expands the equipment's coverage radius, making it suitable for feeding needs in large-area breeding sheds. At the same time, the docking valve 13 structure facilitates the quick disassembly, replacement, and cleaning of the extended feed throwing pipe 14, improving the convenience of equipment maintenance.

[0029] like Figure 3 As shown, each docking valve 13 is bent upwards at an angle, causing the extended feed throwing tube 14 to extend upwards at an angle of 5-20° with the horizontal plane. This angled trajectory extends the feed's flight distance, further increasing the throwing range and coverage area, while avoiding the problem of feed piling up in the center due to close-range vertical falls. This angle range is suitable for most livestock shed conditions, balancing throwing distance and uniformity, making it highly practical.

[0030] like Figures 1 to 7As shown in Example 1, the working principle of the multi-scenario, all-area centrifugal rotary feed throwing device is as follows: During operation, the entire equipment is directly fixed to the central aisle of the breeding shed with bolts. First, the equipment is powered and fed through the integrated circuit of the central aisle. The equipment is started manually through the control switch on the shore. The motor 9 inside the main housing 4 starts and drives the top feeder 7 to rotate at high speed. Feed enters the feeding chamber 10 inside the feeder 5 through the feed pipe 6 via the intermediate passage conveying pipe. As the amount of feed in the feeding chamber 10 increases, the feed rises and enters the feeding chamber 11. Under the diversion and guidance of the three guide baffles 12 inside the feeding chamber 11, the feed is evenly distributed into the three circumferentially evenly distributed throwing pipes 8, preventing feed accumulation, deviation, and blockage. The high-speed rotation of the feed thrower 7 generates a strong centrifugal force, which quickly throws the feed inside the feed throwing pipe 8 out. The extended feed throwing pipe 14, connected by the docking valve 13, is obliquely thrown into the water in the aquaculture shed, effectively extending the feed throwing trajectory and expanding the throwing coverage radius. The equipment features 360° centrifugal rotation for feeding, allowing a single unit to provide feeding to the entire pond area without any blind spots. During operation, the integrated circuit provides stable material and power supply, eliminating the risks of wire entanglement, damage, or leakage. The structure is stable and the operation is smooth.

[0031] Example 2, as Figure 8 As shown, a multi-scenario, all-area centrifugal rotary feed throwing device is provided, mainly used for shrimp feeding in ponds. The difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, the centrifugal rotary feed throwing assembly 3 is fixed to the floating body 1 floating on the pond surface by the bracket 2. The feed pipe 6 feeds the shrimp in real time through the conveying pipe on the shore. The motor 9 is controlled and powered in real time by the control switch and the power supply on the shore. The feed line of the conveying pipe, the control line of the control switch, and the power supply line are all integrated into one unit and fed to the centrifugal rotary feed throwing assembly 3.

[0032] like Figure 8 As shown in Example 2, the working principle of the multi-scenario, all-area centrifugal rotary feed throwing device is as follows: During operation, the entire device is stably suspended in the center of the pond water without the need for shore support, making deployment convenient. First, the device is powered and fed via an integrated shore-based circuit. The device is then manually started via a shore-side control switch. The motor 9 inside the main housing 4 starts and drives the top feeder 7 to rotate at high speed. Feed enters the feeding chamber 10 inside the feeder 5 through the feed pipe 6 via the onshore conveying pipe. As the amount of feed in the feeding chamber 10 increases, the feed rises and enters the feeding chamber 11. Under the diversion and guidance of the three guide baffles 12 inside the feeding chamber 11, the feed is evenly distributed into the three circumferentially evenly distributed throwing pipes 8, thus preventing feed accumulation, deviation, and blockage. The high-speed rotation of the feed thrower 7 generates a strong centrifugal force, which quickly throws the feed inside the feed throwing pipe 8 out. The extended feed throwing pipe 14, connected by the docking valve 13, is then obliquely thrown into the pond water, effectively extending the feed throwing trajectory and expanding the feeding coverage radius. The equipment features 360° centrifugal rotation for feeding, allowing a single unit to provide feeding to the entire pond area without any blind spots. During operation, the integrated circuit provides stable material and power supply, eliminating the risks of wire entanglement, damage, or leakage. The structure is stable and the operation is smooth.

[0033] Example 3, as Figures 9 to 12 As shown, a multi-scenario, all-area centrifugal rotary feed throwing device is provided, mainly used for feeding shrimp in ponds. The difference between this embodiment and embodiment two is that, based on embodiment two, an avoidance groove 15 is provided above the extended throwing pipe 14 away from the docking valve 13, and a flared flip sleeve 16 that completely covers the avoidance groove 15 is rotatably installed above the extended throwing pipe 14. An inner sliding groove 17 extending axially is provided below the extended throwing pipe 14, and an outer sliding groove 18 that is inclined and cooperates with the inner sliding groove 17 is provided on both sides of the flared flip sleeve 16. A sliding rod 19 that can slide in the groove passes through both the outer sliding groove 18 and the inner sliding groove 17. Nuts 20 that lock the sliding rod 19 are threaded at both ends of the sliding rod 19. The relative position of the extended throwing pipe 14 and the flared flip sleeve 16 can be changed by moving the sliding rod 19, thereby changing the size of the final throwing outlet. With its adjustable structure consisting of a chute and slide bar 19, the opening and closing size of the feeding outlet can be flexibly adjusted, thereby precisely controlling the feeding flow rate and the dispersion of the feeding. The outlet can be enlarged to achieve large-flow feeding, which is suitable for shrimp density farming. The outlet can be reduced to achieve small-flow, fine feeding, which is suitable for shrimp larvae farming. This multi-purpose machine greatly improves the adaptability of the equipment to different operating conditions.

[0034] like Figures 11 to 12As shown, an inner lug 21 is connected to the upper part of the extended feed throwing pipe 14 near the docking valve 13, and an outer lug 22 is connected to the upper part of the flared-mouth flipping sleeve 16 near the docking valve 13. The inner lug 21 and the outer lug 22 are hinged together. The flipping angle of the flared-mouth flipping sleeve 16 with the outer lug 22 as the reference is 0-35°. The hinged flipping structure, combined with the 0-35° adjustable flipping angle, can change the opening arc of the feed throwing outlet and the feed spreading angle. The larger the angle, the wider the feed spreading range. The feed throwing width can be flexibly adjusted according to the pond size and stocking density, further improving the equipment's versatility and adapting to the feeding needs of ponds of different sizes.

[0035] Continue as Figures 11 to 12 As shown, the entire linear array of the inner chute 17 has multiple limiting grooves 23 that can limit the movement of the slide rod 19, wherein the cross-sectional shape of the limiting groove 23 is triangular. The triangular limiting grooves 23 of the linear array can precisely lock the slide rod 19 after sliding adjustment, preventing the slide rod 19 from shifting or the sleeve from loosening during high-speed rotation and vibration of the equipment, ensuring the stability of the adjustment size of the discharge outlet, ensuring that the discharge flow rate and discharge range are constant during long-term operation, and improving the stability and reliability of equipment operation.

[0036] like Figures 9 to 12 As shown in Example 3, the working principle of the multi-scenario, all-area centrifugal rotary feed throwing device is as follows: During operation, the entire device is stably suspended in the center of the pond water without the need for shore support, making deployment convenient. First, the device is powered and fed via an integrated shore-based circuit. The device is then manually started via a shore-side control switch. The motor 9 inside the main housing 4 starts and drives the top feeder 7 to rotate at high speed. Feed enters the feeding chamber 10 inside the feeder 5 through the feed pipe 6 via the onshore conveying pipe. As the amount of feed in the feeding chamber 10 increases, the feed rises and enters the feeding chamber 11. Under the diversion and guidance of the three guide baffles 12 inside the feeding chamber 11, the feed is evenly distributed into the three circumferentially evenly distributed throwing pipes 8, thus preventing feed accumulation, deviation, and blockage. The high-speed rotation of the feed thrower 7 generates a strong centrifugal force, which quickly throws the feed inside the feed throwing pipe 8 out. The feed is then obliquely thrown into the pond water through the extended feed throwing pipe 14 connected by the docking valve 13, effectively extending the feed throwing trajectory and expanding the feeding coverage radius.

[0037] For different aquaculture conditions, the feeding parameters of the equipment can be adjusted in advance: by loosening the nuts 20 at both ends, the sliding rod 19 moves inside the inner sliding groove 17 and the outer sliding groove 18, and is fixed in place with the triangular limiting groove 23. The opening and closing range and the flipping angle (0-35°) of the flared flipping sleeve 16 can be adjusted to precisely change the flow area and feeding diffusion angle of the feeding outlet, thereby adapting to different needs such as small-flow fine feeding of shrimp larvae, large-flow broad-spectrum feeding of adult shrimp, and full-coverage feeding of ponds of all sizes. The equipment features 360° centrifugal rotation for feeding, allowing a single unit to provide feeding to the entire pond area without any blind spots. During operation, the integrated circuit provides stable material and power supply, eliminating the risks of wire entanglement, damage, or leakage. The structure is stable and the operation is smooth.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.

An outer sliding groove is provided on both sides of the flared, tilting sleeve, which is inclined and works in conjunction with the inner sliding groove. A sliding rod that can slide within the groove passes through both the outer and inner sliding grooves. Nuts that lock the sliding rod are threaded at both ends. By moving the sliding rod, the relative position of the extended material throwing pipe and the flared, tilting sleeve can be changed, thereby changing the size of the final material throwing outlet.
