Description

Technical Field

[0001] This invention belongs to the field of aquaculture equipment technology, specifically relating to a large-capacity aquaculture visual feedback intelligent feeding device that prevents feed blockage. It is suitable for precise feeding operations in various aquaculture waters (ponds, cages, reservoirs, etc.), and is especially suitable for intelligent feeding in scenarios with large-capacity feed storage and easy feed blockage. Background Technology

[0002] In aquaculture, feeding is a crucial step in ensuring the growth of farmed fish and improving aquaculture efficiency. Traditional aquaculture feeding methods mostly rely on manual feeding or simple mechanical feeding, which have many drawbacks: Firstly, manual feeding is labor-intensive, inefficient, and has poor feeding uniformity, which can easily lead to local feed accumulation and insufficient feed in some areas. This not only wastes feed but also pollutes the water quality of the aquaculture area due to feed accumulation. Secondly, simple mechanical feeding devices often lack anti-clogging structures. The feed is easily compressed by gravity in the hopper, causing bridging and blockage, which interrupts feed delivery and affects the continuity of feeding. Thirdly, the feed throwing mechanism of existing feeding devices is mostly fixed-angle or single-direction, which cannot achieve wide-area and uniform throwing and is difficult to adapt to the distribution of fish in different areas. Fourthly, existing devices lack effective intelligent monitoring and adjustment mechanisms, and cannot perceive changes in fish distribution and activity in real time. They can only feed according to fixed parameters, which cannot achieve precise feeding and further aggravates feed waste and water pollution problems. To address the aforementioned issues, while some improved feeding devices exist in the existing technology, attempting to add a stirring mechanism to prevent clogging or adjust the nozzle angle, they still have shortcomings: the anti-clogging mechanism is mostly a single stirring blade, which has limited effect in breaking up arches and preventing clogging, and is prone to damaging feed particles; the nozzle drive mechanism has a complex structure and cannot achieve coordinated lateral reciprocating and pitching movements, resulting in poor evenness of spraying; and it lacks an integrated visual feedback and intelligent adjustment system, making it impossible to adjust feeding parameters in real time according to the dynamics of the fish school, which makes it difficult to meet the needs of large-scale and refined aquaculture. Therefore, developing an intelligent feeding device that can effectively solve hopper blockage, achieve uniform feed distribution, and dynamically adjust feeding parameters according to fish population distribution has become an urgent technical problem to be solved in the field of aquaculture equipment. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing aquaculture feeding devices, such as frequent feed blockage, uneven distribution, lack of intelligent adjustment, and serious feed waste. It provides a large-capacity aquaculture visual feedback intelligent feeding device that prevents feed blockage. Through the coordinated operation of an anti-bridging mechanism, a composite drive and adjustment mechanism, and an AI visual monitoring mechanism, it achieves feed anti-blockage, precise distribution, and intelligent adjustment, thereby reducing labor intensity, improving feed utilization, protecting aquaculture water quality, and ensuring aquaculture benefits.

[0004] This invention employs the following technical solution: a large-capacity, visually-feeding intelligent feeding device for aquaculture with anti-clogging mechanism, comprising a hopper, an anti-bridging mechanism, a feed conveying pipe, a feed spreading host, a booster, a feed diversion pipe, a feed nozzle, a composite drive and adjustment mechanism, a synchronous transmission and reciprocating drive mechanism, an AI visual monitoring mechanism, and a controller. The core of this device is to prevent feed clogging through the anti-bridging mechanism, achieve uniform spreading through the coordinated composite drive and reciprocating drive mechanism, and achieve intelligent adjustment through the linkage of AI visual monitoring and the controller. This solves the defects of existing devices, such as frequent clogging, uneven spreading, and inaccurate feeding. The overall structure is stable, easy to operate, and adaptable to various aquaculture scenarios, effectively improving feed utilization and reducing aquaculture costs.

[0005] The hopper has a conical hollow structure with a feed inlet at the top and a discharge outlet at the bottom. The bottom discharge outlet is fixedly connected to one end of the feed conveying pipe via a flange for temporary storage and guidance of the feed. A support frame is fixedly connected to the bottom of the hopper and is mounted on a support base. The support base is made of heavy-duty steel plate, which can enhance the overall stability of the device, prevent shaking during feeding, and ensure smooth transmission of each mechanism. The conical structure can use gravity to guide the feed to flow to the bottom discharge outlet, reducing the adhesion and accumulation of feed on the inner wall.

[0006] The anti-bridging mechanism is located at the bottom of the hopper and fits tightly against the inner wall of the hopper. It includes a stirring drive shaft, upper loosening stirring blades, middle flexible stirring blades, lower arch-breaking stirring blades, a bottom scraping and arch-breaking disc, and a stirring motor. It is used to prevent feed from bridging and blocking at the bottom of the hopper due to gravity compression, ensuring continuous and smooth feed delivery. The stirring motor is fixed to the outside of the bottom of the hopper by a motor bracket. The output shaft passes through a sealed bearing at the bottom of the hopper and is fixedly connected to the lower end of the stirring drive shaft by a coupling. The sealed bearing can prevent feed leakage and moisture from entering the motor, extending the service life of the motor.

[0007] The feed conveying pipe is made of rigid PVC pipe, with one end fixedly connected to the feed inlet of the feed spreading host. It is used to stably convey the feed discharged from the hopper to the feed spreading host. The rigid PVC pipe is corrosion-resistant, lightweight, and has a smooth inner wall, which can reduce feed conveying resistance and prevent feed residue from clogging the pipe. The feed spreading host is fixedly mounted on the device frame and has an internal receiving cavity. The booster is rotated and installed in the receiving cavity. The booster and the feed spreading host are connected by a dedicated drive device to pressurize the feed to a preset pressure, providing sufficient power for high-speed and uniform feed spreading. The servo motor can achieve precise speed adjustment, thereby controlling the feed pressurization pressure and conveying speed.

[0008] The feed diversion pipeline adopts a flexible, swingable structure made of flexible corrugated pipe for feed diversion and stable delivery. The flexible corrugated pipe can bend and adjust its posture synchronously with the lateral reciprocating movement and pitch swing of the feed nozzle, avoiding interruption of feed delivery due to pipe bending. The branch joint can ensure that the feed diversion of the two paths is uniform, so that the amount of spray from the nozzles on both sides is consistent, further improving the uniformity of spraying.

[0009] The composite drive and adjustment mechanism is fixed on the device frame and includes a base, a support frame, a pitch drive shaft, a nozzle swing frame, a drive motor, a shaft seat, a power transmission flexible shaft, and a synchronous rotating shaft. It drives the feed nozzle to achieve pitch and swing, adjusting the vertical height and coverage area of ​​the feed spray. The base is fixedly connected to the device frame via expansion bolts. The support frame has a U-shaped structure, with its bottom fixedly connected to the base via bolts. The pitch drive shaft is hinged between the two side walls of the support frame via bearings. The nozzle swing frame is fixedly connected to the pitch drive shaft via a flat key and has a sliding groove at the top. The drive motor is a servo motor, fixed to the outer side wall of the support frame via a motor bracket. The output shaft is fixed to the shaft seat via a flat key. The shaft seat is fixedly connected to one end of the power transmission flexible shaft, and the other end of the power transmission flexible shaft is connected to the synchronous rotating shaft. The synchronous rotating shaft is hinged inside the nozzle swing frame and extends to the outside, connecting to the synchronous transmission and reciprocating drive mechanism. The servo motor provides high driving precision, enabling precise adjustment of the pitch angle to meet the spraying needs of different aquaculture areas.

[0010] The synchronous transmission and reciprocating drive mechanism is connected to the synchronous rotating shaft of the composite drive and adjustment mechanism. It includes a transmission swing arm, a first ball joint connector, a second ball joint connector, a first transmission link, and a second transmission link. This drives the feed nozzle to achieve lateral reciprocating movement and adjusts the horizontal coverage of the feed spray. The transmission swing arm is a long strip structure, with its middle section fixedly connected to the extension end of the synchronous rotating shaft via a flat key. It can swing circumferentially around the axis of the synchronous rotating shaft. Hinge holes are provided at both ends of the transmission swing arm. One end of each of the first and second ball joint connectors is hinged to the hinge holes at both ends of the transmission swing arm via pins, and the other end is threaded to one end of each of the first and second transmission links. The other ends of each of the first and second transmission links are hinged to the moving block at the bottom of the feed nozzle via pins. This converts the circumferential swing of the transmission swing arm into the reciprocating sliding of the moving block, thereby driving the feed nozzle to move laterally reciprocally. The reciprocating frequency is adjustable.

[0011] The AI ​​visual monitoring mechanism, fixed to the top of the device frame, includes a monitoring mounting bracket, a horizontal rotating base, a vertical tilting pan-tilt unit, and a high-definition image acquisition unit. It is used to collect images of fish distribution, activity levels, and feed distribution in aquaculture areas from all angles, providing data support for dynamic adjustments by the controller. The monitoring mounting bracket is a columnar structure, fixed to the device frame at the bottom with bolts and to the horizontal rotating base at the top. The horizontal rotating base has a built-in rotary motor, the output of which is fixedly connected to the vertical tilting pan-tilt unit, allowing it to rotate the vertical tilting pan-tilt unit and the high-definition image acquisition unit 360° horizontally. The vertical tilting pan-tilt unit has a built-in tilting motor, the output of which is fixedly connected to the high-definition image acquisition unit, enabling vertical tilt adjustment of the high-definition image acquisition unit, eliminating blind spots. The high-definition image acquisition unit is a high-definition industrial camera with a built-in image transmission module, capable of transmitting image data in real time.

[0012] The controller is a PLC controller, fixedly installed in the control box of the device. It is electrically connected to the anti-bridging mechanism, the feed spreading host, the composite drive and adjustment mechanism, the synchronous transmission and reciprocating drive mechanism, and the AI ​​visual monitoring mechanism. It has a built-in AI image analysis algorithm to receive image data transmitted by the AI ​​visual monitoring mechanism, analyze and identify fish density, distribution location, activity level, feed spreading uniformity, and coverage, and dynamically adjust the motion parameters of each mechanism to achieve precise feed spreading. The control box has a waterproof and dustproof structure, which can adapt to the humid environment of aquaculture and extend the service life of the controller. At the same time, a wireless communication module can be added to realize remote control and further improve the convenience of operation.

[0013] As a further optimization of the present invention, the stirring drive shaft of the anti-bridging mechanism is fixedly connected to the output shaft of the stirring motor. The upper loosening stirring blades, the middle flexible stirring blades, the lower arch-breaking stirring blades, and the bottom scraping arch-breaking disc are fixed sequentially from top to bottom along the stirring drive shaft. The upper loosening stirring blades are radial, and their length is adapted to the inner diameter of the upper part of the hopper, which can initially loosen the feed in the upper part of the hopper and destroy the feed accumulation structure. The middle flexible stirring blades are inclined flexible structures, forming a 45° angle with the stirring drive shaft, which can adaptively bend according to the feed accumulation state to avoid rigid stirring damaging the feed particles. The lower arch-breaking stirring blades are close to the bottom of the hopper, which can break the compression state of the feed at the bottom and prevent bridging from the root. This further improves the anti-blocking effect and ensures that the feed falls smoothly.

[0014] As a further optimization of the present invention, the base of the composite drive and adjustment mechanism is fixedly connected to the support frame, the pitch drive shaft is hinged between the two side walls of the support frame, the nozzle swing frame is fixedly connected to the pitch drive shaft and has a sliding groove at the top. The sliding groove is a long strip through groove that slides in cooperation with the moving block at the bottom of the feed nozzle, which can ensure that the moving block slides smoothly back and forth and avoid jamming. The output shaft of the drive motor is fixed to the shaft seat, the shaft seat is connected to one end of the power transmission flexible shaft, and the other end of the power transmission flexible shaft is connected to the synchronous rotating shaft. The synchronous rotating shaft is hinged inside the nozzle swing frame and extends to the outside to connect with the synchronous transmission and reciprocating drive mechanism. The power transmission flexible shaft can adapt to the pitch swing of the nozzle swing frame, ensuring stable power transmission and avoiding transmission interruption, realizing the coordinated linkage of the composite drive and reciprocating drive mechanism, thereby driving the feed nozzle to realize the composite motion of lateral reciprocating and pitch swing, improving the uniformity of spreading and the coverage area.

[0015] As a further optimization of the present invention, the transmission swing arm of the synchronous transmission and reciprocating drive mechanism is fixed to the synchronous rotation shaft at the middle, and its two ends are connected to the first transmission connecting rod and the second transmission connecting rod respectively through the first ball joint connector and the second ball joint connector; the bottom of the feed nozzle is provided with a moving block, which is slidably disposed in the slide groove, and the other ends of the first transmission connecting rod and the second transmission connecting rod are hinged to the moving block; wherein, the first ball joint connector and the second ball joint connector can adaptively adjust the angle to avoid jamming during transmission, ensuring that the feed nozzle moves smoothly and continuously in the lateral reciprocating direction, and can also adapt to the pitch swing of the nozzle swing frame to ensure smooth compound motion, so that the feed is sprinkled without dead angles and more evenly, effectively reducing feed waste.

[0016] As a further optimization of the present invention, the horizontal rotating base of the AI ​​visual monitoring mechanism is fixed to the top of the monitoring mounting bracket, and the vertical tilting gimbal is fixed to the output end of the horizontal rotating base. The high-definition image acquisition unit is installed on the vertical tilting gimbal, which can drive the vertical tilting adjustment of the high-definition image acquisition unit to achieve all-round monitoring of the aquaculture water area without blind spots. The high-definition image acquisition unit can be equipped with an infrared sensing module, which can collect image data normally at night or in low light conditions, expanding the applicable scenarios of the device and ensuring intelligent monitoring and precise adjustment around the clock to adapt to different aquaculture environment requirements.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The invention has a significant anti-clogging effect and protects the integrity of the feed: The invention is equipped with a multi-level anti-bridging mechanism. The upper layer loosening, the middle layer shearing, the lower layer arch breaking, and the bottom scraping work together to completely break the feed bridging structure and avoid hopper blockage. The middle layer flexible stirring blades and the lower layer arch breaking stirring blades are made of flexible materials, which can adapt to the feed accumulation state and avoid rigid stirring from damaging the feed particles, thus ensuring the integrity of the feed.

[0018] 2. This invention provides uniform and wide-ranging feed distribution: Through the coordinated operation of the composite drive and adjustment mechanism and the synchronous transmission and reciprocating drive mechanism, the feed nozzle achieves a composite motion of lateral reciprocating movement and pitching oscillation. Combined with the feed nozzle orifice design, the feed is evenly distributed in a fan shape over the aquaculture area, solving the problems of uneven distribution and limited coverage of traditional devices, and adapting to the needs of different scales of aquaculture.

[0019] 3. The AI ​​visual monitoring mechanism of this invention can realize all-round monitoring of aquaculture waters, collect data on fish distribution, activity level and feed throwing status in real time. The controller analyzes the data through AI algorithm and dynamically adjusts the motion parameters of each mechanism to accurately match the feed throwing amount, range and angle with the fish distribution, minimize feed waste and avoid feed accumulation and water pollution.

[0020] 4. The various mechanisms of this invention are reliably connected. The composite drive and adjustment mechanism is driven by a servo motor, which ensures smooth transmission and precise adjustment. The feed diversion pipeline adopts a flexible structure and can be adjusted synchronously with the movement of the nozzle to ensure the continuity of feed delivery. The controller can realize automated control and can also be equipped with a wireless communication module to realize remote control, reducing labor intensity and improving the convenience of operation.

[0031] II. Working Process of this Embodiment The large-capacity aquaculture visual feedback intelligent feeding device for anti-clogging feed provided in this embodiment operates in a sequential manner, with each mechanism cooperating in coordination, as detailed below: 1. Feeding and Anti-bridging Operation: Aquaculture feed is poured into the top feed inlet of hopper 3. Under its own gravity, the feed flows along the conical inner wall of hopper 3 towards the bottom discharge outlet. Simultaneously, the controller starts the stirring motor of the anti-bridging mechanism 4. The stirring motor drives the stirring drive shaft 41 to rotate, which in turn drives the upper loosening stirring blades 42, the middle flexible stirring blades 43, the lower anti-bridging stirring blades 44, and the bottom scraping anti-bridging disc 45 to rotate synchronously. The upper loosening stirring blades 42 stir the feed in the upper part of hopper 3. The feed undergoes initial mixing to break down its aggregate structure and keep it loose. The rotating flexible mixing blades 43 in the middle layer shear and tumble the feed in the middle of the hopper 3, further loosening the feed and preventing the formation of a dense layer. The lower arch-breaking mixing blades 44 rotate close to the bottom of the hopper 3 to break up the compressed state of the feed and prevent bridging. The arch-breaking teeth of the bottom scraping and arch-breaking disc 45 continuously scrape the feed at the outlet of the hopper 3, breaking up the bridging structure that has been formed, ensuring that the feed falls smoothly into the feed conveying pipe 6 and avoiding blockage.

[0032] 2. Feed conveying and pressurization: Feed enters the feed conveying pipe 6 from the bottom of the hopper 3 and is conveyed along the feed conveying pipe 6 to the receiving cavity of the feed throwing host 7; the controller controls the dedicated drive device built into the feed throwing host 7 to start, driving the pressurizer 8 to rotate at high speed. The pressurizer 8 applies centrifugal pressure to the feed in the receiving cavity, pressurizing the feed to the preset pressure of 0.3-0.5MPa. The pressurized feed is discharged from the discharge end of the feed throwing host 7 and enters the feed diversion pipe 10.

[0033] 3. Feed diversion and guidance: The feed diversion pipe 10 divides the pressurized feed into two paths, which are then delivered to the feed nozzles 12 on both sides. Since the feed diversion pipe 10 uses a flexible corrugated pipe, when the feed nozzles 12 move back and forth and swing up and down, the feed diversion pipe 10 can bend and swing synchronously to maintain the continuity of feed delivery and avoid interruption of feed delivery due to pipe bending.

[0034] 4. Nozzle Drive and Attitude Adjustment: The controller starts the drive motor 135 of the composite drive and adjustment mechanism 13. The output shaft of the drive motor 135 drives the bearing seat 136 to rotate, and the bearing seat 136 drives the power transmission flexible shaft 137 to rotate, which in turn drives the synchronous rotating shaft 1310 to rotate continuously around its axis. The synchronous rotating shaft 1310 drives the transmission swing arm 141 to swing circumferentially around the axis of the synchronous rotating shaft 1310. The two ends of the transmission swing arm 141 drive the first transmission connecting rod 144 and the second transmission connecting rod 145 to reciprocate through the first ball joint connector 142 and the second ball joint connector 143, which in turn drives the moving block 122 at the bottom of the feed nozzle 12 to swing along the nozzle. The slide groove 1341 on the frame 134 slides back and forth, realizing the lateral reciprocating movement of the feed nozzle 12. The reciprocating frequency is adjustable, ranging from 10 to 20 times / minute. At the same time, the drive motor 135 drives the pitch drive shaft 133 to rotate slowly. The pitch drive shaft 133 drives the nozzle swing frame 134 to swing up and down around the axis of the pitch drive shaft 133, thereby driving the feed nozzle 12 to swing back and forth in pitch angle, with the swing angle ranging from -15° to 45°. The first ball joint connector 142 and the second ball joint connector 143 can adaptively adjust their angles to avoid jamming during transmission, ensuring that the lateral reciprocating movement and pitch swing of the feed nozzle 12 are smooth and continuous.

[0035] 5. Intelligent Monitoring and Dynamic Adjustment: Simultaneously with the feed nozzle 12 preparing to distribute feed, the controller activates the AI ​​visual monitoring mechanism 5. The horizontal rotating base 52 drives the vertical tilting gimbal 53 and the high-definition image acquisition unit 54 to rotate 360° horizontally. The vertical tilting gimbal 53 drives the high-definition image acquisition unit 54 to adjust its vertical tilt, achieving comprehensive monitoring of the aquaculture area. The high-definition image acquisition unit 54 transmits the collected image data of fish distribution, fish activity, and feed distribution status to the controller in real time. The controller, through its built-in AI image analysis algorithm, identifies the density, distribution location, and activity level of the fish, as well as the uniformity and coverage of the feed distribution. Based on the analysis results, the controller dynamically adjusts... The motion parameters of each mechanism are as follows: If the fish density in a certain area is high, the controller adjusts the speed of the drive motor 135 of the composite drive and adjustment mechanism 13 to increase the pitch angle and lateral reciprocating frequency of the nozzles in the corresponding direction of that area, and at the same time adjusts the output pressure of the feed dispensing host 7 to increase the feed delivery volume; if the fish density is low, the controller adjusts in the opposite direction to reduce the feed delivery volume and avoid feed waste; if the feed is not evenly distributed, the controller adjusts the transmission frequency of the synchronous transmission and reciprocating drive mechanism 14 to adjust the reciprocating speed of the feed nozzles 12 to ensure that the feed is evenly distributed; when the distribution or activity of the fish changes, the AI ​​visual monitoring mechanism 5 senses and feeds back to the controller in real time, and the controller triggers adjustments in a timely manner to ensure the optimal feeding effect.

[0036] 6. Feed Spreading and Operation Completion: The pressurized feed is sprayed out at high speed through the nozzle diversion hole of the feed nozzle 12. Under the combined action of the feed nozzle 12's lateral reciprocating movement and pitching oscillation, the feed is evenly spread into the aquaculture water area in a fan-shaped coverage manner. Throughout the feeding process, the anti-bridging mechanism 4, feed conveying mechanism, drive adjustment mechanism, and AI visual monitoring mechanism 5 work together continuously. The controller adjusts in real time until the preset feeding amount is completed. The controller then controls each mechanism to shut down in sequence, and the feeding operation is completed.

[0037] Example 2 This embodiment is an optimized version of Embodiment 1. The difference between Embodiment 1 and Embodiment 1 is that: the middle layer flexible stirring blade 43 and the lower layer arch-breaking stirring blade 44 are both made of silicone material, which is more flexible and can better adapt to the feed accumulation state, while avoiding the breakage of feed particles; the high-definition image acquisition unit 54 has a built-in infrared sensing module, which can normally acquire image data at night or in low light conditions, expanding the applicable scenarios of the device; the controller adds a wireless communication module, which can realize remote control. Staff can use a mobile APP or computer terminal to view the status of fish in the aquaculture area and the feeding situation in real time, and remotely adjust the feeding parameters, improving the convenience of operation.

[0038] The remaining structures, connections, and working processes of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

[0039] Working principle of the overall technical solution of the feed spreading device of the present invention: The working principle of this feed spreading device revolves around feed feeding, anti-clogging, conveying, driving, spreading, and intelligent monitoring and adjustment. These processes are carried out sequentially, with each mechanism cooperating to achieve precise, uniform, and efficient feed spreading. The specific working process is as follows: Step 1: Feeding and Anti-bridging Operations (Hopper 3, Anti-bridging Mechanism 4) Feed first enters hopper 3 from the top. Hopper 3 has a conical structure, which temporarily stores and guides the feed, allowing it to slowly move towards the discharge port at the bottom of hopper 3 under its own gravity, preparing it for subsequent conveying operations. Because feed is prone to bridging and clogging at the bottom of hopper 3 under the pressure of gravity, affecting the continuity of conveying, the anti-bridging mechanism 4 located at the bottom of hopper 3 is activated simultaneously.

[0040] The anti-bridging mechanism 4 mainly consists of a stirring drive shaft 41, upper loosening stirring blades 42, middle flexible stirring blades 43, lower arch-breaking stirring blades 44, and a bottom scraping and arch-breaking disc 45. Its specific working process is as follows: After the stirring motor of the anti-bridging mechanism 4 starts, it provides rotational power through the stirring drive shaft 41, driving the upper loosening stirring blades 42, middle flexible stirring blades 43, lower arch-breaking stirring blades 44, and bottom scraping and arch-breaking disc 45 to rotate synchronously. The upper loosening stirring blades 42 are radially distributed, initially stirring the feed in the upper part of the hopper 3, breaking the initial accumulation structure of the feed, and keeping the feed in a loose state. The middle flexible stirring blades 43... 3 is an inclined flexible mixing blade that shears and tumbles the feed in the middle of hopper 3 during rotation, further loosening the feed and preventing the formation of a dense layer in the middle. The lower arch-breaking mixing blade 44 is close to the bottom of hopper 3 and powerfully mixes the feed at the bottom through high-speed rotation, breaking the compressed state of the feed at the bottom of the bin and preventing feed bridging from the source. The bottom scraping and arch-breaking disc 45 is located directly above the discharge port of hopper 3. The arch-breaking teeth on the disc rotate with the mixing drive shaft 41, continuously scraping and breaking the feed at the discharge port, directly destroying the formed bridging structure, ensuring that the feed can fall smoothly and continuously from the bottom of hopper 3 into the subsequent feed conveying pipe 6, avoiding blockage. Among them, the middle flexible mixing blade 43 and the lower arch-breaking mixing blade 44 are made of flexible material and can bend adaptively according to the accumulation state of the feed. They can effectively break arches and prevent blockage, while avoiding excessive crushing of feed particles by rigid mixing, ensuring the integrity of the feed.

[0041] Step 2: Feed delivery and pressurization After being processed by the anti-bridging mechanism 4, the feed smoothly enters the feed conveying pipe 6 from the bottom of the hopper 3. The feed conveying pipe 6 is fixedly connected to the feed spreading host 7, which smoothly conveys the feed into the feed spreading host 7. The booster 8 inside the feed spreading host 7 rotates at high speed under the drive of a dedicated drive device, pressurizing the feed entering the feed spreading host 7. Through the rotational force of the booster 8, the feed is pressurized to a preset pressure, and then the pressurized feed is pushed to the discharge end of the feed spreading host 7, providing sufficient power for the subsequent high-speed spreading of the feed and ensuring that the feed can reach the preset spreading range.

[0042] Step 3: Feed diversion and guidance (feed diversion pipe 10) The pressurized feed is discharged from the outlet of the feed dispensing unit 7 and diverted through the feed diversion pipe 10. One end of the feed diversion pipe 10 is fixedly connected to the outlet of the feed transfer pipe 9, and the other end is connected to the feed nozzles 12 on both sides, so that the feed is evenly distributed to the feed nozzles 12 on both sides. In order to cooperate with the subsequent swinging movement of the feed nozzles 12, the feed diversion pipe 10 adopts a flexible swinging structure, which can adjust its own posture synchronously with the reciprocating movement and pitching swing of the feed nozzles 12, so as to maintain the continuity of feed delivery and avoid the feed diversion pipe 10 bending and feed delivery interruption caused by the movement of the feed nozzles 12, ensuring that the feed can be stably delivered into the feed nozzles 12.

[0043] Step 4: Nozzle drive and attitude adjustment (composite drive and adjustment mechanism 13, synchronous transmission and reciprocating drive mechanism 14) As feed is delivered to feed nozzle 12, the compound drive and adjustment mechanism 13 is activated, driving the synchronous transmission and reciprocating drive mechanism 14 to work together to realize the lateral reciprocating movement and pitch angle reciprocating oscillation of feed nozzle 12, adjusting the attitude of feed nozzle 12 for uniform feed distribution. The specific working process is as follows: Operation of the composite drive and adjustment mechanism 13: The composite drive and adjustment mechanism 13 is the core drive and adjustment component of the device, mainly composed of a base 131, a support frame 132, a pitch drive shaft 133, a nozzle swing frame 134, a drive motor 135, a shaft seat 136, a power transmission flexible shaft 137, a synchronous rotation shaft 1310, and other components. After the drive motor 135 of the composite drive and adjustment mechanism 13 starts, its output shaft is fixedly connected to the bearing seat 136. The power is transmitted to the power transmission flexible shaft 137 through the bearing seat 136, and then the power transmission flexible shaft 137 is fixedly connected to the synchronous rotating shaft 1310, transmitting the power to the synchronous rotating shaft 1310. At the same time, two independent and coordinated movements are realized: one is rotation drive, in which the power drives the synchronous rotating shaft 1310 to rotate continuously around its own axis through the above transmission path, providing a power source for the synchronous operation of the synchronous transmission and reciprocating drive mechanism 14; the other is pitch swing drive, in which the pitch drive shaft 133 serves as the swing fulcrum and is hinged to the nozzle swing frame 134. When the pitch drive shaft 133 rotates, it drives the nozzle swing frame 134 to swing up and down around the axis of the pitch drive shaft 133, thereby directly driving the feed nozzle 12 connected to the nozzle swing frame 134 to swing back and forth at the pitch angle, adjusting the height of the feed throwing and the vertical coverage range.

[0044] Operation of the synchronous transmission and reciprocating drive mechanism 14: The synchronous transmission and reciprocating drive mechanism 14 is a lateral reciprocating drive component for the nozzle, mainly composed of a transmission swing arm 141, a first ball head connector 142, a second ball head connector 143, a first transmission link 144, a second transmission link 145, and a synchronous rotating shaft 1310. The synchronous rotating shaft 1310 of the composite drive and adjustment mechanism 13 serves as the power input shaft of the synchronous transmission and reciprocating drive mechanism 14. Its rotational motion is directly transmitted to the hinge center of the transmission swing arm 141, driving the transmission swing arm 141 to swing around the hinge center in a circular motion. The two ends of the transmission swing arm 141 are respectively hinged to the first transmission link 144 and the second transmission link 145 through the first ball joint connector 142 and the second ball joint connector 143. The circular swing of the transmission swing arm 141 is transmitted through the first transmission link 144 and the second transmission link 145, which drives the moving block 122 below the feed nozzle 12 to slide inside the slide groove 1341 of the nozzle swing frame 134, thereby converting it into the reciprocating lateral movement of the feed nozzle 12. The first ball joint connector 142 and the second ball joint connector 143 can adaptively adjust their angles to effectively avoid jamming during transmission, ensuring that the lateral reciprocating movement of the feed nozzle 12 is smooth and continuous, and adjusting the horizontal coverage range of the feed spray.

[0045] 3. Collaborative operation: The reciprocating lateral drive and compound drive of the synchronous transmission and reciprocating drive mechanism 14 are synchronized with the pitch swing drive of the adjustment mechanism 13. When the compound drive and adjustment mechanism 13 drives the nozzle swing frame 134 to swing up and down, the transmission arm 141, the first transmission link 144, the second transmission link 145 and other components of the synchronous transmission and reciprocating drive mechanism 14 adjust their spatial posture synchronously with the nozzle swing frame 134. This ensures that the feed nozzle 12 can maintain the pitch angle while moving laterally, thus realizing the compound motion of the feed nozzle 12 and laying the foundation for the large-scale and uniform spreading of feed.

[0046] Step 5: Intelligent Monitoring and Dynamic Adjustment While the feed nozzle 12 is preparing to distribute feed and all other mechanisms are operating normally, the AI ​​visual monitoring mechanism 5 is activated to monitor the distribution of fish and the feed distribution status in the aquaculture area in real time, providing data support for precise adjustment of feed distribution. The specific working process is as follows: The AI ​​visual monitoring mechanism 5 is the intelligent monitoring component of the device, mainly composed of a monitoring mounting bracket 51, a horizontal rotating base 52, a vertical tilting pan-tilt unit 53, and a high-definition image acquisition unit 54. The monitoring mounting bracket 51 of the AI ​​visual monitoring mechanism 5 is fixed to the frame of the feed spreading device, allowing the AI ​​visual monitoring mechanism 5 to move synchronously with the entire device. The high-definition image acquisition unit 54 (high-definition camera) is mounted on the vertical tilting pan-tilt unit 53, which is connected to the monitoring mounting bracket 51 via the horizontal rotating base 52. The horizontal rotating base 52 can drive the vertical tilting pan-tilt unit 53 and the high-definition image acquisition unit 54 to rotate 360° horizontally, and the vertical tilting pan-tilt unit 53 can drive the high-definition image acquisition unit 54 to adjust its vertical tilt, achieving all-round monitoring of different areas and angles of the aquaculture water area, effectively avoiding blind spots. The high-definition image acquisition unit 54 collects real-time image data such as fish density, fish distribution location, fish activity, and the trajectory, coverage, and uniformity of subsequent feed spreading in the aquaculture water area, and transmits the collected image data to the device's controller in real time.

[0047] After receiving image data, the controller analyzes and processes the images using built-in AI algorithms to identify the distribution characteristics and activity levels of the fish, as well as any deficiencies in the feed distribution process (such as mismatch between the distribution range and the fish population, uneven distribution, etc.). Based on the analysis results, it automatically and dynamically adjusts the motion parameters of various related mechanisms: including adjusting the rotation angle of the pitch drive shaft 133 and the rotation frequency of the synchronous rotation shaft 1310 of the composite drive and adjustment mechanism 13, thereby adjusting the pitch swing angle and lateral reciprocating frequency of the feed nozzle 12; adjusting the output pressure of the feed dispensing host 7, thereby adjusting the feed delivery speed and dispensing force; ensuring that the feed flow rate, dispensing range, dispensing height, and dispensing landing point are precisely matched with the distribution position and density of the fish population, avoiding feed waste, and preventing excessive feed accumulation that could lead to water pollution. When the distribution and activity levels of the fish in the aquaculture area change, the AI ​​visual monitoring mechanism 5 can sense the changes in real time and feed them back to the controller, triggering the controller to make dynamic adjustments to ensure that the feed dispensing is always in the optimal state.

[0048] Step 6: Feed spreading and operation completion After all the above steps of preparation and adjustment are completed, the pressurized feed is continuously transported to the feed nozzle 12 through the feed diversion pipe 10, and sprayed out at high speed through the feed nozzle 12. Driven by the compound drive and adjustment mechanism 13 and the synchronous transmission and reciprocating drive mechanism 14, the feed nozzle 12 performs a compound motion of lateral reciprocating movement and pitch angle reciprocating oscillation, so that the sprayed feed is evenly and widely scattered in the aquaculture water area. At the same time, the AI ​​visual monitoring mechanism 5 continuously monitors and the controller continuously adjusts to ensure that the feed scattering is always matched with the distribution of fish, so as to achieve precise and efficient feed scattering and complete the entire feed delivery operation.

[0049] Throughout the entire operation, the anti-bridging mechanism 4, feed conveying pipe 6, feed spreading host 7, booster 8, feed diversion pipe 10, composite drive and adjustment mechanism 13, synchronous transmission and reciprocating drive mechanism 14, AI visual monitoring mechanism 5, and feed nozzle 12 work together in an orderly manner. Each mechanism operates in sequence, and the names of each structure remain consistent throughout the process. This ensures the continuity and stability of feed delivery, as well as the accuracy and uniformity of feed spreading, effectively improving feed utilization, reducing breeding costs, and ensuring breeding efficiency.
