Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to a fully automatic feed dispensing device for the domestication of fish fry. Background Technology

[0002] Fish fry domestication is a key link in the aquaculture industry chain. Its core objective is to guide fish fry to form feeding habits and improve aggregation through regular feeding, thus laying the foundation for subsequent adult fish farming.

[0003] Current traditional techniques for feeding and acclimatizing fish fry have several limitations, making it difficult to meet the demands for efficient and precise acclimatization. Firstly, they are highly dependent on manual feeding, resulting in low efficiency and precision. Traditional fry acclimatization relies heavily on manual hand-held feeders, with the feeding area constantly shifting with the operator. This leads to scattered feeding, making it difficult for fry to develop a concentrated feeding habit and prolonging the acclimatization period. Furthermore, judging the amount of feed depends entirely on experience; overfeeding results in waste and water quality issues, while underfeeding leads to uneven growth and even death of weaker fry, severely impacting acclimatization survival rates. Secondly, existing devices cannot monitor the amount of remaining feed or dynamically adjust the feeding amount based on fry feeding behavior, species, and growth stage, failing to meet the requirements for refined acclimatization. Additionally, existing devices lack feed mixing capabilities; clumped feed can cause localized feeding difficulties, further exacerbating uneven fry growth and resulting in poor acclimatization outcomes.

[0004] Therefore, a fully automatic feed dispensing device for fish fry domestication is proposed. Summary of the Invention

[0020] 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.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1-4 This invention provides a fully automatic feed dispensing device for fish fry domestication, comprising: Support frame 1, on which control system 2 and transverse connecting seat 3 are installed; The bait storage mechanism is mounted on the support frame 1, and a stirring component is installed inside the bait storage mechanism. Floating ring 4 is connected to transverse connecting seat 3 via a flexible connecting part; Automatic feeding component, which is installed on the horizontal connecting seat 3, is used to feed bait into the float ring 4; A quantitative conveying mechanism is installed on the support frame 1. The quantitative conveying mechanism is used to convey the bait in the bait storage mechanism to the automatic dispensing component. The visual monitoring system is installed on the outer wall of the quantitative conveying mechanism, with the working end of the visual monitoring system facing the floating ring 4; Among them, the visual monitoring system, the mixing component, the automatic dispensing component, and the quantitative conveying mechanism are all electrically connected to the control system 2; With this configuration, the float ring 4 in this invention is connected to the transverse connecting seat 3 via a flexible connecting part, which can stably float on the water surface and fix the feeding area, preventing the bait from spreading with the water flow. The fish fry can continuously feed in the fixed area, quickly form a concentrated feeding habit, and shorten the domestication period. At the same time, the fixed feeding area makes it easy for the fish fry to gather, reducing the waste of bait in non-feeding areas, reducing the risk of water pollution, strengthening the domestication effect of the fish fry, and improving the feeding efficiency. This invention uses a visual monitoring system to capture data such as the amount of remaining feed, fish fry density, and feeding behavior in the floating ring 4 in real time, and transmits the data to the control system. When the amount of remaining feed is detected to be below a threshold, the control system 2 triggers the quantitative conveying mechanism and automatic feeding component to replenish the feed; if the amount of remaining feed is above the threshold, feeding is paused to avoid overfeeding. At the same time, the operator can adjust the output power of the quantitative conveying mechanism through the control system 2 according to the type of fish fry, feeding behavior, and growth stage, thereby accurately controlling the amount of feed delivered, realizing on-demand feeding, and further improving feeding efficiency. This invention prevents the bait from clumping in the bait storage mechanism through a stirring component, ensuring that the bait is loose and easy to transport. The quantitative conveying mechanism accurately delivers the stored bait to the automatic dispensing component, which then directionally dispenses it into the floating ring 4. The entire process requires no manual intervention. Compared with traditional manual feeding, this invention not only significantly reduces the labor intensity of operators but also avoids the problem of uneven feeding caused by human experience errors, improves the consistency of feeding amount and frequency, and enhances the stability of acclimatization effect.

[0023] Further optimization of the plan includes the following bait storage mechanism: Storage housing 5 is mounted on support frame 1, stirring assembly is installed inside storage housing 5, and bottom of storage housing 5 is open. The feeding assembly is mounted on top of the storage housing 5; The top surface of the discharge hopper 6 is fixedly connected to and communicates with the bottom surface of the storage shell 5, and the bottom surface of the discharge hopper 6 is fixedly connected to and communicates with the quantitative conveying mechanism. Screen 7 is detachably connected to the top of discharge hopper 6; The feeding assembly replenishes feed into the storage shell 5, while the stirring assembly continuously operates within the storage shell 5 to prevent feed clumping. When feed falls from the bottom of the storage shell 5 into the discharge hopper 6, the removable screen 7 at the top of the discharge hopper 6 filters the feed, intercepting clumped feed or impurities. Only loose, qualified feed passes through the screen 7 into the discharge hopper 6, from where it is guided to the quantitative conveying mechanism. The removable screen 7 facilitates the later cleaning of intercepted impurities and clumped feed, preventing blockage of the discharge channel, ensuring smooth feed delivery, and guaranteeing the quality of feed entering the quantitative conveying mechanism, laying the foundation for subsequent precise feeding.

[0024] The solution has been further optimized, and the quantitative conveying mechanism includes: A conveying housing 8 is mounted on the support frame 1 and is located below the storage housing 5; a visual monitoring system is mounted on the outer wall of the conveying housing 8. The material guiding assembly includes a feed pipe 9 and a discharge pipe 10. The feed pipe 9 is installed on one side of the top surface of the conveying housing 8, and the discharge pipe 10 is installed on the other side of the bottom surface of the conveying housing 8. The feed pipe 9 is fixedly connected to and communicates with the discharge hopper 6, and the discharge pipe 10 faces the automatic material dispensing assembly. The screw conveyor assembly is installed inside the conveyor housing 8 and is electrically connected to the control system 2. The conveying housing 8 is fixed to the support frame 1, providing protection and support for the internal spiral conveying assembly. A visual monitoring system is installed on its outer wall, which can stably align with the floating ring 4. The feed pipe 9 of the guiding assembly is connected to the discharge hopper 6, serving as the channel for bait to enter the conveying housing 8; the discharge pipe 10 faces the automatic dispensing assembly, responsible for discharging the conveyed bait. When the bait in the discharge hopper 6 enters the conveying housing 8 through the feed pipe 9, the control system 2 starts the spiral conveying assembly. The spiral conveying assembly pushes the bait from the feed pipe 9 end to the discharge pipe 10 end by rotating. The spiral conveying assembly precisely controls the amount of bait conveyed through a controllable rotation speed.

[0025] The scheme is further optimized. The screw conveyor assembly includes auger blades 11 and a first motor 12. The first motor 12 is installed on one side of the conveyor housing 8. The output shaft of the first motor 12 is connected to a rotating shaft 13 via a coupling. The rotating shaft 13 is rotatably connected inside the conveyor housing 8. The auger blades 11 are installed on the rotating shaft 13. The first motor 12 is electrically connected to the control system 2. The output shaft of the first motor 12 drives the rotating shaft 13 to rotate stably within the conveying housing 8 via a coupling, and the auger blades 11 mounted on the rotating shaft 13 rotate synchronously. The auger blades 11 adopt a spiral structure, and when rotating, they utilize the axial thrust generated by the helix angle to gradually push the feed in the conveying housing 8 from the feed pipe 9 side to the discharge pipe 10 side. Since the pitch of the auger blades 11 is fixed, when the first motor 12 maintains a constant speed, the amount of feed pushed per unit time remains consistent; if it is necessary to adjust the conveying amount, the control system 2 only needs to adjust the speed of the first motor 12 to accurately match the feeding needs of the fish fry, avoid overfeeding or underfeeding, and achieve precise control of quantitative conveying.

[0026] Further optimization of the scheme: the visual monitoring system includes a camera 14 electrically connected to the control system 2. The camera 14 is mounted on the outer wall of the conveying housing 8 via a bracket 15, and the camera 14 is located directly above the floating ring 4. The camera 14 is a high-definition infrared camera. Camera 14 captures real-time images of the area inside the float ring 4, recording key information such as the remaining amount of feed and the density of fish fry. This image data is then transmitted to the control system 2 in real-time. The control system 2 uses image recognition algorithms (such as comparing the image features of full and remaining feed amounts and statistically analyzing the percentage of fish fry pixels) to determine if the feed level inside the float ring 4 is below a preset threshold. If it is below the threshold, the control system 2 controls the quantitative feeding mechanism and automatic feeding component to replenish the feed; if it is above the threshold, the control system 2 controls the feeding to be paused. Simultaneously, operators can view the real-time images transmitted by camera 14 through the control system 2, gaining a clear understanding of the fish fry feeding situation and providing a basis for manual intervention, ensuring accurate monitoring and timely adjustments.

[0027] The scheme is further optimized. The automatic material dispensing component includes a second motor 16 installed on the transverse connecting seat 3. The second motor 16 is electrically connected to the control system 2. The output shaft of the second motor 16 is equipped with a turntable 17, which is rotatably connected to the top surface of the transverse connecting seat 3. Several circumferentially spaced material distribution plates 18 are installed on the turntable 17. An annular baffle plate 19 is installed on the top surface of the transverse connecting seat 3 away from the support frame 1. A discharge groove is opened on the side of the annular baffle plate 19 near the floating ring 4. The annular baffle plate 19 covers the several material distribution plates 18. The discharge pipe 10 extends into the annular baffle plate 19. The second motor 16 drives the turntable 17 to rotate at a constant speed on the top surface of the transverse connecting seat 3. Several distribution plates 18 on the turntable 17 rotate synchronously with the turntable. The annular baffle plate 19 covers the distribution plates 18 to prevent the bait from spilling out. As the turntable 17 continues to rotate, when a portion of the divided bait rotates to the discharge chute position of the annular baffle plate 19, the bait falls precisely from the discharge chute into the float ring 4 under the pushing action of the distribution plate 18.

[0028] The design is further optimized so that the stirring assembly includes a third motor 20 and a stirring shaft 21. The third motor 20 is mounted on the side wall of the storage housing 5, and the stirring shaft 21 is mounted on the output end of the third motor 20 via a coupling. The stirring shaft 21 is rotatably connected inside the storage housing 5, and the third motor 20 is electrically connected to the control system 2. Several stirring wheels 22 are installed on the stirring shaft 21 at intervals, and a connecting rod 23 is installed between two adjacent stirring wheels 22. The third motor 20 drives the stirring shaft 21 to rotate inside the storage shell 5 via a coupling. The stirring wheel 22 on the stirring shaft 21 rotates synchronously with the connecting rod 23. The stirring wheel 22 agitates the bait inside the storage shell 5 through its blade structure, breaking up any clumps. The connecting rod 23 between adjacent stirring wheels 22 enhances the overall agitation, preventing bait accumulation and stagnation in localized areas of the storage shell 5. The continuous agitation keeps the bait inside the storage shell 5 loose, allowing it to fall smoothly into the discharge hopper 6 from the bottom opening. This prevents bait clumps from blocking the discharge channel, ensuring that the subsequent quantitative conveying mechanism can stably receive the bait and guaranteeing the continuity of the entire feeding process.

[0029] Further optimization of the scheme: the feeding assembly includes a top cover 24 and a feeding hopper 25. The top cover 24 is detachably connected to the top of the storage housing 5. The feeding hopper 25 is installed on the top cover 24 and communicates with the inner cavity of the storage housing 5. A check valve 26 is installed inside the feeding hopper 25. The top cover 24 can be opened to clean or repair the inside of the storage shell 5; the check valve 26 in the feed hopper 25 adopts a one-way structure. When adding bait, the bait pushes open the check valve 26 under the action of gravity and enters the storage shell 5; the check valve 26 is used to reduce the entry of external debris and moisture into the storage shell 5 through the feed hopper 25, ensuring the cleanliness and dryness of the stored bait and reducing the risk of contamination when fish fry feed.

[0030] Further optimization of the scheme: the flexible connection part includes a first vertical rod 27 and a second vertical rod 28. The first vertical rod 27 is installed on the bottom surface of the transverse connecting seat 3, and the second vertical rod 28 is installed on the side wall of the float ring 4. An elastic rope 29 is installed between the first vertical rod 27 and the second vertical rod 28. An annular flexible gasket 30 is installed on the inner side wall of the float ring 4. The elastic rope 29 has the ability to stretch and swing. When the water surface in the breeding pond fluctuates, the float ring 4 can float slightly up and down or shift left and right with the water waves. The elastic rope 29 will adapt to the expansion and contraction or bending, preventing the float ring 4 from being rigidly stretched and deformed or displaced. At the same time, it always confines the float ring 4 within the preset feeding area, preventing food from being wasted due to drifting with the float ring. The annular flexible pad 30 on the inner wall of the float ring 4 is made of soft material (such as rubber). When the fish fry gather to feed inside the float ring 4, their bodies will not be scratched by the hard inner wall of the float ring 4, protecting the integrity of the fish fry's body surface, reducing the injury rate of fish fry during the domestication process, and improving the survival rate.

[0031] Further optimization of the design involves installing several wing plates 31 on the bottom sidewall of the support frame 1, with several anchor bolts 32 detachably connected to the wing plates 31, ensuring the stability of the support frame 1.

[0032] The design is further optimized by providing two independent chambers inside the storage shell 5. The bottom of each chamber is connected to the feed hopper 6. The two chambers are used to store different types of feed, and each chamber is equipped with an independent stirring component. During operation, the control system 2 switches the feed supply to the corresponding chamber according to the growth stage of the fish fry, or mixes and feeds them in proportion to meet the nutritional needs of fish fry at different stages.

[0033] The scheme was further optimized by installing a water temperature sensor and a dissolved oxygen sensor on the support frame 1. Both the water temperature sensor and the dissolved oxygen sensor are electrically connected to the control system 2. The probes of the water temperature sensor and the dissolved oxygen sensor are inserted into the water of the aquaculture pond. At the same time, a miniature aeration nozzle is installed on the inner wall of the float ring 4. The aeration nozzle is connected to an external aeration pump through an air pipe. The aeration pump is electrically connected to the control system 2.

[0034] During operation, if the water temperature is lower than the preset temperature, the control system 2 will automatically reduce the feeding frequency (to reduce the digestive burden on the fry); if the dissolved oxygen is lower than the threshold, the oxygenation pump will be triggered to start, and the oxygenation nozzles will oxygenate the water in the float ring 4, so as to avoid the fry's feeding enthusiasm decreasing due to unsuitable environment and improve the survival rate of domestication.

[0035] The solution is further optimized by installing an adjustable-angle photovoltaic panel on the top of the support frame 1. The photovoltaic panel is connected to an energy storage battery and an inverter. After the power output from the photovoltaic panel is converted by the inverter, part of it is directly used by the device (control system 2, motor, camera 14, etc.), and the excess power is stored in the energy storage battery. This reduces the device's dependence on the external power grid, which is especially suitable for outdoor open-air aquaculture ponds and reduces long-term energy consumption costs.

[0036] The design is further optimized by installing a liquid feed storage tank on the horizontal connecting seat 3. The bottom of the liquid feed storage tank is connected to a metering pump via a pipe. The metering pump is electrically connected to the control system 2, and its outlet faces the float ring 4. A solenoid valve, electrically connected to the control system 2, is installed on the pipe. When fry need to be fed liquid feed (such as egg yolk liquid or algae liquid), the liquid feed storage tank stores the liquid feed. The control system 2 controls the solenoid valve and the metering pump to start, pumping the liquid feed into the float ring 4. This design allows for the separate or mixed feeding of solid and liquid feeds, adapting to the different dietary needs of fry from juvenile to adult fish, and completing the entire acclimatization cycle without changing the equipment.
