Description

Technical Field

[0001] This invention belongs to the field of fishpond feeding technology, and particularly relates to an automatic feeding system and method for fishpond aquaculture. Background Technology

[0002] Fishponds are enclosed or semi-enclosed bodies of water that are artificially excavated or transformed from natural water bodies for raising fish or other aquatic economic animals. They are one of the main places for aquaculture. During the process of fishpond farming, it is often necessary to feed the fish in the fishpond to meet their nutritional needs for growth.

[0003] The document with publication number CN214431114U discloses an intelligent fishpond assistant robot based on NB-IoT. The robot includes: a frame, a storage bin inside the frame near the thruster, a control bin inside the frame away from the thruster, two buoyancy bins below the frame, and thrusters on the sides of one end of the two buoyancy bins. It realizes automatic feeding of fish in the fishpond, removal of algae in the water, and monitoring of water temperature. Users can monitor temperature data in real time and remotely control the robot through a mobile app. It also has the ability to work continuously, thus solving problems such as uneven feeding, algae proliferation, temperature control, inability to be unattended, and lack of remote monitoring in existing fishpond farming. However, in the actual feeding process, the leftover feed and excrement produced after the fish eat will affect the overall quality of the fishpond water. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that residual feed and excrement produced by fish after feeding can affect the overall quality of the water in fishponds, and to propose an automatic feeding system and method for fishpond aquaculture.

The feed storage mechanism consists of a box, a cover plate, and a discharge pipe, and is used for the storage and discharge of feed. A bulk feed adjustment component is installed at the bottom of the feed storage mechanism. The bulk feed adjustment component is connected to the top of the support float and is used to scatter and feed the feed from the feed storage mechanism within different ranges. Two floating boxes are arranged in a mirror-symmetrical manner on both sides of the supporting floating plate. A sealed door is provided on one side of each floating box to improve the buoyancy of the supporting floating plate.

[0006] As a further description of the above technical solution: The feeding and cleaning components include: A net is laid and rolled up inside a floating box. One side of the net extends to the outside of the floating box.

[0009] As a further description of the above technical solution: The tightening component includes: Two connecting slots are symmetrically arranged on both sides of the floating box. One side of the connecting slot is connected to one side of the floating box. A sliding sleeve is slidably connected in the connecting slot. A moving rod is connected to one side of the sliding sleeve. One end of the moving rod extends to the other side of the connecting slot and is connected to a connecting seat. The tension wheel, rotatably connected to two connecting seats, is used to limit and guide the laying net and adjust its tension.

[0010] As a further description of the above technical solution: The tightening assembly also includes: Two fixed slide rods are symmetrically arranged in the connecting groove seat. The fixed slide rods are connected to the inside of the connecting groove seat, and the sliding sleeve is slidably connected to the outer surface of the fixed slide rods. A return spring is sleeved on the outer surface of the fixed slide rod, and its two ends are connected to one side of the slide sleeve and one side of the connecting groove seat, respectively.

[0011] As a further description of the above technical solution: The bulk material adjustment assembly includes: A bottom box is connected to the top of the supporting floating plate. A fixed motor is fixedly installed inside the bottom box via a mounting base. One end of the output shaft of the fixed motor is connected to a connecting shaft. The end of the connecting shaft extends to the outside of the bottom box and is connected to a rotating disk. A fixed circular box is connected to the top of the rotating disk.

[0012] As a further description of the above technical solution: The bulk material adjustment assembly also includes: A ratchet gear is connected to the outer surface of the connecting shaft, and the ratchet gear is located below the rotating disk; Two levers are rotatably connected to one side of the inner wall of the fixed circular box.

[0013] As a further description of the above technical solution: The bulk material adjustment assembly also includes: The bulk feed trough is connected to the bottom of the feed storage mechanism and to the top of the bottom box. The bulk feed trough has a groove that expands from the inside to the outside. The rotating disk is rotatably connected to the groove, and the groove helps to guide the feed to be scattered.

[0014] An automatic feeding method for fishpond aquaculture specifically includes the following steps: S1. The staff places the feed into the feed storage mechanism. Then, the drive device moves the feed storage mechanism in the fishpond through the support float, so that the feed storage mechanism moves to the appropriate position and stops. S2. Before feeding, the feeding and cleaning components are activated, causing the net to unfold in the water and create a feeding area for the fish. During this process, the tightening components adjust the tension of the net. S3. The feed pipe at the bottom of the feed storage mechanism is opened, allowing the feed to fall into the bulk feed adjustment component. The feed is then scattered in the fishpond at the location where the net is laid, and the fish collectively feed at the location where the net is laid. S4. After feeding the fish, the net is returned to the floating box by the feeding and cleaning components, and the excrement and leftover feed attached to the net are collected and cleaned.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, by setting up a feeding and cleaning component, the automated deployment and retrieval of the net are achieved through the coordinated operation of the telescopic mechanism and the drive motor. After the net is deployed, a centralized feeding area is formed, which allows the feed to be accurately distributed in the target area, reducing feed waste and promoting fish aggregation, which is convenient for feeding management. During the retrieval process, the multiple cleaning settings of the eccentric vibration of the vibrating roller, the scraping of the scraper, and the air jet are combined to efficiently remove excrement and residue attached to the net surface, keep the net clean and prevent secondary pollution. The vibrating roller achieves a compound motion of rotation and revolution through gear transmission, which greatly enhances the vibration effect. Combined with the air jet, it can accelerate the drying of the net surface and improve the efficiency of impurity separation, realize the clean recycling of excrement and residue, avoid the impact on the fish pond water, and ensure the quality of the fish pond water.

[0016] 2. In this invention, by setting up a bulk feed adjustment component, the feed can be efficiently and evenly scattered outwards through the synchronous operation of the rotating disk and the bulk feed deflector. Combined with the groove structure of the bulk feed trough, directional scattering is achieved, improving the accuracy of feed distribution. When the fixed motor rotates counterclockwise, the ratchet gear drives the rotating disk to scatter the feed through the actuating block and the support block, ensuring the controllability of the scattering amount. When the motor rotates clockwise, the ratchet gear drives the actuating rod to deflect and reset under the action of the tension spring. Then, by rotating the gear disk and the drive gear, the angle of the bulk feed deflector is adjusted, flexibly changing the scattering angle and orientation of the feed, realizing dynamic adjustment of the scattering range, and adapting to different operating scenarios.

[0017] 3. In this invention, by setting up a tightening component, the tensioning wheel and the laying net are in continuous contact, and under the action of the return spring, the laying net is dynamically guided and precisely limited, which effectively ensures the constant tension of the laying net during the unfolding process and avoids slack or wrinkles. At the same time, the contact-type limiting mechanism of the tensioning wheel enhances the system's ability to correct the deviation of the laying net, protects the laying net material from excessive stretching damage, and maintains operational stability.

[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.

[0021] Please see Figures 1-13 The present invention provides a technical solution: An automatic feeding system for fishpond aquaculture includes a supporting float 2, with multiple drive devices 6 installed at the bottom of the supporting float 2 for driving, and also includes: Feed storage mechanism 1 is located above the supporting floating plate 2. Feed storage mechanism 1 consists of a box, a cover plate and a feeding pipe, and is used for the storage and feeding of feed. The bulk feed adjustment component 8 is located at the bottom of the feed storage mechanism 1 and is connected to the top of the support float 2. It is used to scatter and feed the feed from the feed storage mechanism 1 in different ranges. Two floating boxes 5 are arranged in a mirror image symmetrically on both sides of the supporting floating plate 2.

Two sets of tightening components 4 are set on one side of the floating box 5 to adjust the posture of the feeding and cleaning component 3; Feeding and cleaning component 3 includes: Net 303 is laid and rolled up inside floating box 5. One side of net 303 extends to the outside of floating box 5. When unfolded, it provides a support place for feed and prevents fish excrement from falling into the bottom of the fishpond and polluting the water quality. Two symmetrically arranged telescopic mechanisms 301 are connected to one side of the floating box 5. One end of the telescopic mechanism 301 is connected to a connecting rod 302. One end of the connecting rod 302 is connected to one side of the laying net 303. The telescopic mechanism 301 is used to drive the laying net 303 to extend and retract. The telescopic mechanism 301 is composed of multiple telescopic cylinders, a lead screw, a lead screw sleeve and a drive source. Multiple vibrating rollers 307 are arranged in a linear array inside the floating box 5 and are in close contact with the laying net 303. The vibrating rollers 307 are rotatably connected to the floating box 5 and are used to vibrate and remove impurities from the laying net 303 when it is recycled. The take-up roller 311 is rotatably connected to the floating box 5. One side of the laying net 303 is connected to the take-up roller 311. The take-up roller 311 rotates itself to drive the laying net 303 to be wound. A connecting box 304 is connected to one side of the floating box 5. A drive motor 312 is fixedly installed inside the connecting box 304 by a mounting plate. One end of the output shaft of the drive motor 312 extends into the interior of the floating box 5 and is connected to one side of the take-up roller 311. A water pump 310 is installed in the connecting box 304. A water pump pipe is connected to one side of the water pump 310, one end of which extends into the floating box 5. A drain pipe is connected to the other end of the water pump 310, one end of which extends into the outside of the connecting box 304. The nozzle 306 is connected to the top of the inner wall of the floating box 5 and is used to blow and dry the laying net 303 to help improve the separation of feed or impurities on the laying net 303. The bellows 305 is connected to the top of the floating box 5. Multiple connecting pipes are connected to the bottom of the bellows 305. One end of the connecting pipe extends into the interior of the floating box 5 and is connected to the nozzle 306. Multiple scrapers 308 are connected inside the floating box 5. One side of the scraper 308 is attached to one side of the laying net 303, and is used to scrape and remove feed and impurities on the laying net 303. The receiving hopper 309 is connected inside the floating box 5, and one side of the receiving hopper 309 is attached to the laying net 303. The receiving hopper 309 is used to collect feed and impurities on the laying net 303. The bottom of the receiving hopper 309 has multiple filter holes for drainage. Multiple rotating shafts 316 are arranged in a circular array within the vibrating roller 307, and the rotating shafts 316 are rotatably connected within the vibrating roller 307; Multiple counterweights 317 are provided, and a connector 318 is connected to one side of each counterweight 317. The connector 318 is connected to a rotating shaft 316. The rotating shaft 316 drives the counterweights 317 to rotate eccentrically, causing the vibrating roller 307 to vibrate. Two fixed gears 314 are respectively located on both sides inside the vibrating roller 307. A fixed shaft 313 is connected to one side of the fixed gear 314. The fixed shaft 313 is rotatably connected to the vibrating roller 307. One end of the fixed shaft 313 extends to the outside of the vibrating roller 307 and is connected to one side of the inner wall of the floating box 5. A transmission gear 315 is meshed with the outer periphery of the fixed gear 314. The transmission gear 315 is connected to the rotating shaft 316.

[0022] The specific implementation method is as follows: In the initial state, the laying net 303 is neatly rolled up in the floating box 5. When feeding begins, the drive motor 312 and the telescopic mechanism 301 start synchronously. While the winding roller 311 smoothly unwinds, the telescopic mechanism 301 quickly unfolds the laying net 303 into the fishpond water. Then, the feed storage mechanism 1 starts to feed. The rotating disk 803 drives the feed dispensing plate 805 to rotate, evenly scattering the feed in the area of ​​the laying net 303 to form a concentrated feeding area, effectively attracting fish to gather. After feeding, the device switches to the recycling mode. The winding roller 311 and the telescopic mechanism 301 run in opposite directions. During the recycling process, the scraper 308 and the collection hopper 309 work together to remove large impurities. The vibrating roller 307 generates high-frequency vibration through a unique transmission structure, causing the residues attached to the surface of the laying net 303 to completely fall off. At the same time, the airflow sprayed from the nozzle 306 assists in cleaning and accelerates drying. Impurities are collected by the collection hopper 309, and the filtered water is discharged by the water pump 310.

[0023] Bulk material adjustment assembly 8 includes: The bottom box 802 is connected to the top of the support float 2. A fixed motor 804 is fixedly installed inside the bottom box 802 via a mounting base. One end of the output shaft of the fixed motor 804 is connected to a connecting shaft. The end of the connecting shaft extends to the outside of the bottom box 802 and is connected to a rotating disk 803. A fixed round box 806 is connected to the top of the rotating disk 803. Multiple feed spreading plates 805 are arranged in a circular array on the outer periphery of the fixed circular box 806. A rotating shaft is connected to one side of each feed spreading plate 805. One end of the rotating shaft extends into the interior of the fixed circular box 806 and is rotatably connected to the fixed circular box 806. The feed spreading plates 805 adjust the feed spreading range by adjusting their own deflection direction. Multiple drive gears 807 are connected to one end of a rotating shaft, and a rotating gear disk 808 is meshed with the bottom of the multiple drive gears 807. The rotating gear disk 808 is connected to one end of a connecting shaft. Ratchet 809 is connected to the outer surface of the connecting shaft and is located below the rotating disk 803; Two levers 810 are rotatably connected to one side of the inner wall of the fixed circular box 806. The levers 810 mesh with the ratchet gear 809 and are used to limit the ratchet gear 809 in one direction. A support block 811 is attached to one side of the lever 810 and is connected to one side of the inner wall of the fixed circular box 806. It is used to provide one-way support and limit the lever 810. The cross-sectional shape of the support block 811 is L-shaped. A support spring 812 is provided between the support block 811 and the lever 810. The two ends of the support spring 812 are connected to the lever 810 and the support block 811, respectively. The bulk feed trough 801 is connected to the bottom of the feed storage mechanism 1 and the top of the bottom box 802. The bulk feed trough 801 has a groove that expands from the inside to the outside. The rotating disk 803 is rotatably connected to the groove. The groove helps guide the feed to be scattered.

[0024] The specific implementation method is as follows: The output shaft of the fixed motor 804 is connected to the ratchet 809. When the ratchet 809 rotates counterclockwise, it drives the rotating disk 803 to rotate through the actuating block and the support block 811, causing the feed scattering plate 805 to throw the falling feed outward. At the same time, the groove structure on the feed trough seat 801 assists in the directional diffusion of the feed. When the fixed motor 804 rotates clockwise, the ratchet 809 pushes the actuating rod 810 to deflect, and under the reset action of the support tension spring 812, it drives the rotating gear disk 808 to rotate. The rotating gear disk 808 meshes with the drive gear 807, and the drive gear 807 further adjusts the deflection angle of the feed scattering plate 805, changing the direction and distance of feed throwing, thereby realizing the dynamic adjustment of the throwing range, flexibly changing the flying angle and orientation of the feed, and realizing the dynamic adjustment of the throwing range to adapt to different operating scenarios.

[0025] Tightening component 4 includes: Two connecting slots 403 are symmetrically arranged on both sides of the floating box 5. One side of the connecting slot 403 is connected to one side of the floating box 5. A sliding sleeve 405 is slidably connected inside the connecting slot 403. A moving rod 407 is connected to one side of the sliding sleeve 405. One end of the moving rod 407 extends to the other side of the connecting slot 403 and is connected to a connecting seat 402. Tensioning wheel 401 is rotatably connected to two connecting seats 402. Tensioning wheel 401 is used to limit and guide the laying net 303 and adjust its tension. Two fixed slide rods 406 are symmetrically arranged in the connecting groove 403. The fixed slide rods 406 are connected to the inside of the connecting groove 403, and the sliding sleeve 405 is slidably connected to the outer surface of the fixed slide rods 406. The return spring 404 is sleeved on the outer surface of the fixed slide rod 406, and the two ends of the return spring 404 are respectively connected to one side of the slide sleeve 405 and one side of the connecting groove seat 403.

[0026] The specific implementation method is as follows: After the laying net 303 is led out from the floating box 5, it is guided by the tension wheel 401 to form an L-shaped winding path. During the unfolding or retraction process, the tension change of the laying net 303 causes the tension wheel 401 to move. The return spring 404 then compresses or extends to dynamically adjust the pressure of the tension wheel 401 on the laying net 303. When the speed of the laying net 303 increases, resulting in a decrease in tension, the return spring 404 pushes the tension wheel 401 to increase the contact pressure to prevent the laying net 303 from loosening. When the speed of the laying net 303 decreases or is obstructed, the increased tension forces the tension wheel 401 to overcome the elastic force and retreat to avoid overstretching. This adaptive adjustment process continues to ensure that the laying net 303 is always in a moderately taut state. At the same time, the limiting effect of the tension wheel 401 effectively suppresses the lateral displacement of the laying net 303.

[0027] An automatic feeding method for fishpond aquaculture specifically includes the following steps: S1. The staff places the feed into the feed storage mechanism 1. Then, the drive device 6 drives the feed storage mechanism 1 to move in the fishpond through the support float 2, so that the feed storage mechanism 1 moves to the appropriate position and stops. S2. Before feeding, the feeding and cleaning component 3 is activated, causing the laying net 303 to unfold in the water, forming a feeding area for the fish. During this process, the tightening component 4 adjusts the tension of the laying net 303. S3. The feed pipe at the bottom of the feed storage mechanism 1 is opened, allowing the feed to fall into the bulk feed adjustment component 8. The feed is then scattered in the fishpond at the location where the net 303 is laid, and the fish collectively feed at the location where the net 303 is laid. S4. After feeding the fish, the net 303 returns to the floating box 5 under the action of the feeding and cleaning component 3, and the excrement and residual feed attached to the net 303 are collected and cleaned.

[0028] Working principle: When in use, the operator operates the drive device 6, which drives the feed storage mechanism 1 containing feed to move in the fish pond through the support float 2. When it moves to the appropriate position, the drive device 6 stops, so that the support float 2 and the floating box 5 are stable in the fish pond. Before feeding, the telescopic mechanism 301 and the drive motor 312 start simultaneously. The drive motor 312 drives the take-up roller 311 to rotate, and the take-up roller 311 unwinds the laying net 303. At the same time, the telescopic mechanism 301 drives the laying net 303 to unfold outward. The telescopic mechanism 301 consists of multiple sleeves, lead screws, lead screw sleeves, and a drive source. It is a relatively mature existing technology and will not be described in detail. This allows the laying net 303 to unfold in the water of the fishpond. During feeding, the feed storage mechanism 1 dispenses feed and rotates. Driven by the fixed motor 804, the rotating disc 803 rotates, causing the feed dispersing plate 805 to rotate and distribute the falling feed, concentrating it in the area of ​​the laying net 303. The feed adheres to the laying net 303, thus concentrating the fish in the area of ​​the laying net 303, forming a concentrated fish feeding area, facilitating the feeding and management of the fish. After feeding, when the fish disperse, their excrement and feed residue will adhere to the laying net 303. At this time, the telescopic mechanism 301... The reel operates in the opposite direction to the take-up roller 311, thereby driving the laying net 303 to be retracted into the floating box 5. During the movement of the laying net 303, impurities fall into the collection hopper 309 under the scraping of the scraper 308 and the collection hopper 309. Furthermore, the laying net 303 drives the vibrating roller 307 to rotate during the recycling process. The vibrating roller 307 drives multiple transmission gears 315 to rotate around the fixed gear 314, causing the transmission gears 315 to rotate. The transmission gears 315 drive the rotating shaft 316 to rotate, and the rotating shaft 316 drives... The counterweight 317 rotates, thereby generating eccentric vibration and acting on the laying net 303, making it easier for excrement and feed residue on the laying net 303 to fall off. At the same time, the nozzle 306 in the floating box 5 will deliver the airflow in the bellows 305 to the laying net 303, which will accelerate the drying of the laying net 303 and help separate impurities. Some of the water that enters the receiving hopper 309 will be discharged from the filter hole into the floating box 5 and pumped to the outside of the floating box 5 by the water pump 310. The rotating disk 803 drives the feed dispensing plate 805 to throw the falling feed outwards. This, combined with the grooves in the feed trough 801, enables directional throwing. Simultaneously, when the fixed motor 804 rotates counterclockwise, it drives the ratchet 809 to rotate counterclockwise. The ratchet 809, through the actuating rod 810 and the support block 811, drives the rotating disk 803 to rotate, achieving the throwing and scattering of the feed. When the fixed motor 804 rotates clockwise, it drives the ratchet 809 to rotate clockwise. When wheel 809 contacts lever 810, it causes lever 810 to deflect. Afterward, lever 810 will reset under the action of support spring 812, thereby driving rotating gear 808 to rotate. Rotating gear 808 drives drive gear 807 to rotate. Drive gear 807 drives loose feed plate 805 to deflect, changing the contact angle between loose feed plate 805 and falling feed, thereby changing the angle and direction of feed flight, and realizing the control and adjustment of feed scattering range. During the unfolding and retraction of the laying net 303, the tensioning wheel 401 is always in contact with one side of the laying net 303. Under the action of the return spring 404, the tensioning wheel 401 guides and limits the laying net 303, thereby ensuring the tension of the laying net 303 when it is unfolded.
