Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to a feeding device for shrimp fry farming. Background Technology
[0002] Key steps in shrimp larvae farming include water quality management, feed management, disease prevention and control, and suitable farming facilities. Ensuring clean and stable water quality is the foundation for the healthy growth of shrimp larvae. Regularly cleaning the bottom mud and ensuring appropriate shading and water flow are essential to maintain suitable temperature and oxygen supply. Meanwhile, the rationality and precision of feed feeding plays a crucial role in the growth, development, survival rate, and cost control of shrimp larvae. Traditional shrimp larvae feeding methods often involve direct artificial sowing of feed. This method has many drawbacks. Artificial feeding makes it difficult to accurately control the amount of feed, which can easily lead to overfeeding, resulting in feed waste and water pollution, or underfeeding, causing insufficient nutrition and slow growth of shrimp larvae.
[0003] For example, Chinese patent CN214206839U discloses a timed feeding device for micro-bait specifically for shrimp larvae, including a shell. An hourglass is provided in the inner cavity of the shell. Two round shafts are symmetrically fixedly connected to the center of the left and right side walls of the hourglass. The ends of the round shafts away from the hourglass are movably connected to the left and right side walls of the inner cavity of the shell, respectively. Two first springs are fixedly connected to the upper and lower side walls of the inner cavity of the hourglass, respectively. The same arc-shaped plate is fixedly connected to the end of the first spring on the same side near the center of the hourglass. The upper and lower right side walls of the hourglass are symmetrically provided with through slots. The arc-shaped plates pass through the through slots and are fixedly connected to the fixing plates. The fixing plates are L-shaped. The round shaft on the right side passes through the shell and is movably connected to the flipping mechanism. A first rectangular groove is provided on the right side wall of the shell near the bottom.
[0004] While existing feeding devices can achieve automatic feeding, their feeding uniformity is poor, resulting in uneven feeding of shrimp larvae. Some shrimp larvae become weak and diseased due to insufficient food, affecting their growth, development, and survival rate. To address these issues, a feeding device for shrimp larvae farming is proposed. Utility Model Content
[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a feeding device for shrimp fry farming.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for shrimp fry farming, comprising a feeding device, which includes a feeding motor, a storage tank, and a feeding pipe. A spiral conveying rod is installed inside the feeding pipe. The output end of the feeding motor is fixedly connected to one end of the spiral conveying rod. The device also includes a feeding device, which includes a rotating motor, a fixed frame, an adjusting motor, a fixed plate, a drive gear, and a centrifugal disc. The top of the fixed frame is rotatably connected to the bottom of the centrifugal disc, and the outer edge of the top of the fixed frame is fixedly connected to the bottom of the fixed plate. The output end of the rotating motor is fixedly connected to the bottom of the centrifugal disc. The outer edge of the fixed plate is provided with a ring array of multiple feeding holes, and a telescopic tube is fixedly connected to the outer side of each feeding hole. The bottom output end of the adjusting motor is fixedly connected to the top of the driving gear. A gear ring is rotatably connected to the top of the fixed plate. A ring array of multiple movable gears is rotatably connected to the top of the fixed plate. The outer wall of the top of each movable gear meshes with the outer wall of the gear ring, and a moving plate meshes with the outer wall of the bottom of each movable gear. One end of the moving plate is fixedly connected to one end of the telescopic tube.
[0007] Preferably, the bottom of the adjusting motor is fixedly installed to the top of the fixed plate, and the bottom of the movable plate is slidably connected to the top of the fixed plate.
[0008] Preferably, a support frame is fixedly installed on the bottom outer wall of the storage tank, and an electric push rod is fixedly connected to the outside of the support frame.
[0009] Preferably, a baffle is provided at one end of the electric push rod, and a weighing sensor is fixedly connected to the bottom of one end of the conveying pipe.
[0010] Preferably, an inclined plate is fixedly installed at one end of the conveying pipe, and the top of the support frame is fixedly connected to the bottom of the controller.
[0011] Preferably, the inner side of the support frame is fixedly installed to one end of the material conveying motor.
[0012] Preferably, the inner side of the fixing frame is fixedly connected to the bottom end of the rotating motor.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, a weighing sensor is installed at the outlet of the feeding pipe. When the feed passes through the outlet, the weighing sensor monitors the weight of the feed in real time. Once the set feeding amount is reached, the electric push rod drives the baffle to move to the outlet of the feeding pipe to block the feed from falling onto the inclined plate, thereby achieving precise quantitative feeding. At the same time, the feed slides down the inclined plate onto the centrifugal disc at the bottom of the fixed plate. The rotating motor drives the centrifugal disc to rotate at high speed. When the quantitatively fed feed falls onto the centrifugal disc, it moves rapidly in all directions under the action of centrifugal force. Finally, it is evenly spread outward through multiple feeding holes and telescopic pipes, thereby evenly distributing the feed into the shrimp pond, ensuring uniform feeding of shrimp larvae, reducing individual differences in shrimp larvae caused by uneven feeding, and improving the overall growth quality and survival rate of shrimp larvae.
[0015] 2. In this utility model, the controller turns on the regulating motor, which drives the drive gear to rotate forward / backward, thereby moving multiple moving plates. The moving plates cause the telescopic tube to extend or shorten. When it is necessary to expand the spreading range, the controller increases the speed of the rotating motor and extends the telescopic tube outward. When it is necessary to reduce the spreading range, the controller decreases the speed of the rotating motor and shortens the telescopic tube inward. This controls the distance of feed spreading, quickly adjusts the spreading range, adapts to the size of different shrimp farming ponds, and achieves flexible adjustment of the spreading range.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a feeding device for shrimp fry farming, including a feeding device 1 and a feeding device 2. The feeding device 2 includes a rotating motor 20, a fixed frame 21, an adjusting motor 22, a fixed plate 23, a drive gear 24, and a centrifugal disc 210. The top of the fixed frame 21 is rotatably connected to the bottom of the centrifugal disc 210, and the outer edge of the top of the fixed frame 21 is fixedly connected to the bottom of the fixed plate 23. The output end of the rotating motor 20 is fixedly connected to the bottom of the centrifugal disc 210. The outer edge of the fixed plate 23 has a plurality of feeding holes 29 arranged in a ring array, and a telescopic tube 28 is fixedly connected to the outside of the feeding holes 29. The bottom output end of the adjustable motor 22 is fixedly connected to the top of the drive gear 24. The top of the fixed plate 23 is rotatably connected to the gear ring 25. The top of the fixed plate 23 is rotatably connected to a ring array of movable gears 26. The outer wall of the top of the movable gear 26 meshes with the outer wall of the gear ring 25, and the outer wall of the bottom of the movable gear 26 meshes with the moving plate 27. One end of the moving plate 27 is fixedly connected to one end of the telescopic tube 28. The bottom of the adjustable motor 22 is fixedly installed to the top of the fixed plate 23. The bottom of the moving plate 27 is slidably connected to the top of the fixed plate 23. The inner side of the fixed frame 21 is fixedly connected to the bottom of the rotating motor 20.
[0024] The specific settings and functions of this embodiment are described below: The feed slides down the inclined plate 15 onto the centrifugal disc 210 at the bottom of the fixed plate 23. The rotating motor 20 is turned on, and the controller 3 can adjust the speed of the rotating motor 20. The rotating motor 20 drives the centrifugal disc 210 to rotate at high speed. When the quantitative feed falls onto the centrifugal disc 210, it moves rapidly in all directions under the action of centrifugal force. Finally, it is evenly spread outward through multiple feeding holes 29 and telescopic pipe 28, thereby evenly distributing the feed into the shrimp pond, achieving uniform feed distribution, ensuring uniform feeding of shrimp larvae, reducing individual differences in shrimp larvae caused by uneven feeding, and improving the overall growth quality and survival rate of shrimp larvae.
[0025] Simultaneously, the controller 3 activates the regulating motor 22, which drives the active gear 24 to rotate forward / backward. The gear ring 25 rotates accordingly, causing multiple movable gears 26 to rotate. The outer wall of the movable gears 26 meshes with the outer side of the moving plate 27, causing the moving plate 27 to move. The moving plate 27 drives the telescopic tube 28 to extend or shorten. When it is necessary to expand the spreading range, the controller 3 increases the speed of the rotating motor 20 and extends the telescopic tube 28 outward. When it is necessary to reduce the spreading range, the controller 3 decreases the speed of the rotating motor 20 and shortens the telescopic tube 28 inward. This controls the distance of feed spreading, quickly adjusts the spreading range, adapts to the size of different shrimp farming ponds, and achieves flexible adjustment of the spreading range.
[0026] Example 2: Figure 1 and Figure 2 As shown, the material conveying device 1 includes a material conveying motor 12, a storage tank 13, and a material conveying pipe 14. A screw conveying rod 16 is installed inside the material conveying pipe 14. The output end of the material conveying motor 12 is fixedly connected to one end of the screw conveying rod 16. A support frame 11 is fixedly installed on the outer wall of the bottom end of the storage tank 13, and an electric push rod 17 is fixedly connected to the outer side of the support frame 11. A baffle 18 is provided at one end of the electric push rod 17. A weighing sensor 19 is fixedly connected to the bottom of one end of the material conveying pipe 14. An inclined plate 15 is fixedly installed at one end of the material conveying pipe 14. The top end of the support frame 11 is fixedly connected to the bottom of the controller 3, and the inner side of the support frame 11 is fixedly installed to one end of the material conveying motor 12.
[0027] The overall effect of this embodiment is that by setting a weighing sensor 19 at the outlet of the feed pipe 14, the weighing sensor 19 monitors the weight of the feed in real time when the feed passes through the outlet. Once the set feeding amount is reached, the controller 3 controls the system to immediately stop the feed motor 12 and start the electric push rod 17. The electric push rod 17 drives the baffle 18 to move to the outlet of the feed pipe 14 to block the feed from falling onto the inclined plate 15, thereby achieving precise quantitative feeding.
[0028] The usage and working principle of this device are as follows: When in use, the feeding device 1 is fixed to the side of the shrimp pond via the support frame 11, and the feeding device 2 is fixed to the center of the shrimp pond via the fixing frame 21. First, an appropriate amount of feed is added to the storage tank 13. The parameters of the weighing sensor 19 (i.e., the feeding amount) are set through the controller 3. When feeding is needed into the shrimp pond, the feeding motor 12 is turned on through the controller 3. The feeding motor 12 drives the screw conveyor 16 to rotate. The speed of the screw conveyor 16 can be adjusted by the control system of the controller 3. The feed falls from the storage tank 13 into the feeding pipe 14, passing through the spiral blades... The rotation of the plate pushes the feed forward to the discharge port, and finally it falls onto the inclined plate 15. The feed is conveyed to the feeding device 2 through the inclined plate 15 for feeding. A weighing sensor 19 is installed at the discharge port of the conveying pipe 14. When the feed passes through the discharge port, the weighing sensor 19 monitors the weight of the feed in real time. Once the set feeding amount is reached, the controller 3 controls the system to immediately stop the conveying motor 12 and start the electric push rod 17. The electric push rod 17 drives the baffle 18 to move to the discharge port of the conveying pipe 14 to block the feed from falling onto the inclined plate 15, thereby achieving precise quantitative feeding.
[0029] Feed slides down the inclined plate 15 onto the centrifugal disc 210 at the bottom of the fixed plate 23. The rotating motor 20 is activated, and the controller 3 adjusts its speed. The motor 20 drives the centrifugal disc 210 to rotate at high speed. When the metered feed falls onto the centrifugal disc 210, it moves rapidly outwards under centrifugal force, and is then evenly distributed outwards through multiple feeding holes 29 and the telescopic tube 28. This ensures uniform feed distribution in the shrimp pond, guaranteeing even feeding of the shrimp larvae, reducing individual differences caused by uneven feeding, and improving the overall growth quality and survival rate of the shrimp larvae. Simultaneously, the controller 3 activates the regulating motor 22, which drives the drive gear 24 to rotate forward / backward, thereby moving the moving plate 27. The moving plate 27 then extends or shortens the telescopic tube 28. When it is necessary to expand the spreading range, the controller 3 increases the speed of the rotating motor 20 and extends the telescopic tube 28 outward. When it is necessary to reduce the spreading range, the controller 3 decreases the speed of the rotating motor 20 and shortens the telescopic tube 28 inward. This controls the distance of feed spreading, quickly adjusts the spreading range, adapts to the size of different shrimp farming ponds, and achieves flexible adjustment of the spreading range.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
