Description

Technical Field

[0001] This application relates to the field of feeding training for mandarin fish, and in particular to feeding training devices for mandarin fish fry throughout all stages. Background Technology

[0002] Mandarin fish, also known as perch, generally inhabit still or slow-moving waters, especially lakes with abundant aquatic plants. They exhibit a unique feeding behavior, consuming only live fish and shrimp and refusing dead bait or commercial feed. Large-scale mandarin fish farming has been established in my country, and the process of raising them requires training them to eat a variety of foods to reduce feed costs.

[0003] In existing technologies, when feeding mandarin fish, staff gradually transition from all live bait to all feed. During the acclimatization stage, the amount of live bait is gradually reduced while the amount of feed is gradually increased, thereby achieving the purpose of transitioning to live bait and enabling the mandarin fish to gradually adapt to the feed, which is convenient for later breeding.

[0004] In the existing technologies mentioned above, the amount of feed given by staff mostly depends on human experience. Mandarin fish eat more live bait and less commercial feed, which can easily lead to water pollution due to overfeeding, resulting in diseases in the mandarin fish and reducing the success rate of training them to eat. Improvements are urgently needed. Utility Model Content

[0005] In order to increase the amount of live bait consumed by mandarin fish, improve the efficiency of feeding mandarin fish, and increase the success rate of feeding mandarin fish, this application provides a feeding device for mandarin fish fry throughout the entire feeding process.

[0006] The feeding and acclimatization device for mandarin fish fry provided in this application adopts the following technical solution: It includes a feeding hopper and a water inlet pipe for injecting water into the rearing pond. The feeding hopper has a stirring chamber, and multiple rotating blades for stirring the feed are rotatably connected within the stirring chamber. The feeding hopper is equipped with a first driving component for driving the rotating blades to rotate. The feeding hopper is equipped with a live bait bin for storing live fish and shrimp and a feed bin for storing feed. A first discharge port is opened on one side of the live bait bin, and a second discharge port is opened on one side of the feed bin. The live bait bin and the feed bin... The feed bins are equipped with pushers for propelling live bait and feed, respectively. The pushers are used to push the live bait and feed out. The feeding hopper is equipped with a water inlet pipe connected to the water inlet pipe, and the water inlet pipe is equipped with a water inlet switch. The bottom of the feeding hopper is equipped with a discharge pipe connected to the water inlet pipe, and the discharge pipe is equipped with a switch for controlling the opening and closing of the discharge pipe. The side wall of the discharge pipe is connected to a feeding pipe for adding feed to the feeding pool, and the feeding pipe is equipped with a control component for controlling the opening and closing of the feeding pipe and the discharge pipe.

[0007] By adopting the above technical solution, the operation is divided into three stages: feeding with live bait only, feeding with a mixture of live bait and feed, and feeding with only feed. During feeding with only feed, the pusher pushes live fish and shrimp from the live bait compartment into the feeding bucket. Simultaneously, a suitable amount of water is added to the mixing chamber via a water pipe. Under the action of the rotating blades, the live bait is evenly dispersed in the bucket, achieving natural mixing between the live bait and the water. The rotating blades automatically stun the live bait, preventing it from swimming excessively after feeding and interfering with the mandarin fish's feeding. This also reduces the difficulty of hunting for the mandarin fish, helping them adapt to the artificial feeding rhythm more quickly, accelerating the domestication process from live bait feeding to feed feeding, and improving domestication efficiency. During feeding with a mixture of live bait and feed, the pusher adds the live bait and feed to the mixing chamber in a specific ratio, followed by a small amount of water. Under the action of the rotating blades, the live bait and feed powder are thoroughly mixed. During the rotation process, the feed can be evenly coated on the surface of the live bait, providing mandarin fish with a more nutritious transitional food that is closer to their feed-eating habits. This effectively promotes the transition of mandarin fish from live bait feeding to feed feeding. During injection, the mixed live bait and feed are injected into the rearing pond through the feeding pipe, allowing the feed to adhere better to the live bait, making it easier for mandarin fish fry to eat. For pure feed feeding, the feed is added to the mixing chamber under the action of the feeding device, and then water is added to mix and form a water-feed mixture. The water-feed mixture of pellet feed and water is output through the discharge port, forming a water flow of a certain intensity in the rearing pond. The water flow creates splashes to stimulate the mandarin fish, simulating the dynamics of prey in the natural environment, stimulating their predatory instincts, increasing their willingness to eat the processed live bait, and ensuring their feed intake and growth during the critical period of domestication.

[0008] Preferably, the feeding device includes a feeding plate slidably connected to the live bait bin or the feed bin, and the feeding hopper is provided with two feeding cylinders for pushing the two feeding plates to slide. The tops of both the live bait bin and the feed bin are open, and the first discharge port and the second discharge port are both located away from the feeding hopper. The bottom of the live bait bin is provided with a first guide plate, which extends upward along the direction close to the first discharge port. The bottom of the feed bin is provided with a second guide plate, which extends upward along the direction close to the second discharge port.

[0009] By adopting the above technical solution, both the live bait bin and the feed bin have open tops, allowing for easier addition of live bait and feed and improving the ease of use of the device. Raising the positions of the first and second feed inlets not only increases the storage capacity of the live bait and feed bins but also reduces the risk of live bait and feed slipping, further enhancing the convenience of adding them. Furthermore, using a pusher cylinder to drive the addition of live bait and feed makes the process even more convenient.

[0010] Preferably, a rotating plate is rotatably connected to the top of the feeding hopper, and a control component for controlling the rotation of the rotating plate is provided on the feeding hopper. A weighing device is provided on the rotating plate, and a weighing hopper is provided on the weighing device. A guide hopper is provided on the feeding hopper, and a guide cavity is provided through the guide hopper. The upper side of the guide cavity is used to receive live bait and feed pushed out by the first discharge port and the second discharge port. The bottom opening of the guide cavity is located on the upper side of the weighing hopper.

[0011] By adopting the above technical solution, using a weighing device in conjunction with a feed hopper, the live bait and feed discharged from the live bait bin and feed bin can be weighed. Based on the actual amount of feed required, the live bait and feed can be more accurately proportioned, ensuring the precision of feeding and the efficiency of training mandarin fish fry.

[0012] Preferably, the control component includes a control slider slidably connected within the feeding tube. The control slider has a communicating cavity on its side wall, which extends through the side of the control slider away from the discharge tube. The feeding tube is provided with a second driving member for driving the control slider to move. When the control slider moves away from the feeding tube, it is used to close the discharge tube. At the same time, the communicating cavity is used to connect the discharge tube and the feeding tube.

[0013] By adopting the above technical solution, the control slider can be used to control the opening and closing of the feeding pipe. The connecting cavity makes it easier to discharge the mixed live bait and feed, thus improving the convenience of controlling the opening and closing of the live bait and feed.

[0014] Preferably, the water inlet pipe includes a pressurizing pipe and a discharge pipe. A booster pump is installed on the pressurizing pipe. The water inlet pipe is connected to the pressurizing pipe. A suction seat is provided between the pressurizing pipe and the discharge pipe. The pressurizing pipe is inserted into the suction seat. The discharge pipe is coaxially arranged with the pressurizing pipe. A suction cavity is formed on the periphery of the pressurizing pipe. The suction cavity is connected to the discharge pipe.

[0015] By adopting the above technical solution, the water in the pressurized pipe flows through the suction seat and then into the discharge pipe, generating suction pressure in the suction chamber. The mixture of live bait and feed in the mixing chamber can be discharged under its own weight, and the mixture can also be discharged faster under the suction pressure, thus improving the efficiency and convenience of the mixture discharge.

[0016] Preferably, the feeding hopper is provided with a disinfection seat, the disinfection seat has a disinfection chamber for placing disinfectant, a discharge port is provided on one side of the disinfection seat, a pusher plate is provided in the disinfection chamber, and a third driving component is provided in the disinfection chamber for driving the pusher plate to move.

[0017] By adopting the above technical solution, the staff puts the disinfectant into the disinfection chamber. Under the action of the third driving component, the drug can be pushed out from the discharge port, thereby achieving the effect of adding the drug and realizing the all-round disinfection treatment of live bait. This effectively kills bacteria, parasites and other harmful substances carried on the surface and inside the live bait, blocking the spread of diseases from the source and ensuring the safety of the mandarin fish farming environment.

[0018] Preferably, a rotating rod is rotatably connected to the feeding hopper, the first driving member is used to drive the rotating rod to rotate, the rotating blade is installed on the periphery of the rotating rod, the rotating blade is inclined, and the two ends of the rotating blade are provided with transition arc surfaces.

[0019] By adopting the above technical solution, during use, the rotation of the first driving component is controlled, and the rotation speed of the rotating blades is adjusted to achieve precise control over the degree of live bait dizziness. For mandarin fish that are smaller in size and have weaker predation ability, a lower rotation speed is used to dizzy the live bait to a suitable degree, making it easier for them to prey on it. For mandarin fish that are larger in size and have stronger adaptability, the rotation speed is appropriately increased to adjust the state of the live bait, meeting the special needs of different mandarin fish groups in the first stage of domestication, improving the overall domestication effect, and promoting the refined and scientific development of feed-fed mandarin fish farming.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. Feeding is divided into three stages: feeding with live bait only, feeding with a mixture of live bait and feed, and feeding with only feed. When feeding with only feed, the pusher pushes live fish and shrimp from the live bait compartment into the feeding bucket. At the same time, the water pipe adds appropriate water to the mixing chamber. Under the action of the rotating blades, the live bait is evenly dispersed in the bucket, achieving natural mixing between the live bait and the water. The rotating blades will automatically stun the live bait, preventing it from swimming excessively after feeding and interfering with the mandarin fish's feeding. This also reduces the difficulty for the mandarin fish to catch food, helps them adapt to the rhythm of artificial feeding more quickly, accelerates the domestication process of the mandarin fish from feeding with live bait to feeding with feed, and improves domestication efficiency. When feeding with a mixture of live bait and feed, the pusher adds the live bait and feed to the mixing chamber in a certain proportion, and then a small amount of water is added. Under the action of the rotating blades, the live bait and feed powder are fully mixed. During the rotation process, the feed can be evenly coated on the surface of the live bait, providing the mandarin fish with a more nutritious transitional food that is closer to their feed-eating habits. This effectively promotes the mandarin fish's transition from live bait feeding to feed feeding. During injection, the mixed live bait and feed are injected into the rearing pond through the feeding pipe, allowing the feed to adhere better to the live bait, making it easier for the mandarin fish fry to eat the feed. For pure feed feeding, the feed is added to the mixing chamber under the action of the feeding device, and then water is added to mix and form a water-feed mixture. The water-feed mixture formed by the pellet feed and water is output through the discharge port, forming a water flow with a certain intensity in the rearing pond. The water flow creates splashes to stimulate the mandarin fish, simulating the dynamics of prey in the natural environment, stimulating their predatory instincts, increasing their willingness to eat the processed live bait, and ensuring the mandarin fish's feed intake and growth during the critical period of domestication.

[0022] 2. By using a weighing device in conjunction with a feed hopper, the live bait and feed discharged from the live bait bin and feed bin can be weighed. Based on the actual amount of feed required, the live bait and feed can be more accurately proportioned, ensuring the accuracy of feeding and the efficiency of training mandarin fish fry.

[0023] 3. All three stages stimulate the mandarin fish's predatory instincts through water flow in the inlet pipe, increasing their willingness to feed on treated live bait and ensuring their feed intake and growth during the critical acclimatization period. The first stage uses stun to prevent excessive movement of the live bait after feeding, thus avoiding interference with the mandarin fish's feeding and reducing the difficulty of hunting. This helps the mandarin fish adapt to artificial feeding more quickly, accelerating the acclimatization process from live bait to pre-prepared feed and improving acclimatization efficiency. The second stage involves attaching feed to the live bait, allowing the mandarin fish to consume the feed while eating the live bait. This helps the mandarin fish fry adapt to the feed more effectively, facilitating the efficient transition to pure pre-prepared feed in the later third stage. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0031] This application discloses a feeding and acclimatization device for mandarin fish fry at all stages.

[0032] Example 1

[0033] Reference Figure 1A feeding and acclimatization device for mandarin fish fry at all stages includes a feeding bucket 20, which is a cylindrical bucket with a mixing chamber 1. The bottom of the mixing chamber 1 is conical, and a water inlet pipe 4 for injecting water into the rearing pond is provided at the bottom of the feeding bucket 20. Multiple rotating blades 19 for mixing feed are rotatably connected inside the mixing chamber 1. The rotating blades 19 are inclined and have transition arc surfaces at both ends. A fixing frame 25 is provided on the feeding bucket 20, and a rotating rod 21 for mounting the rotating blades 19 is rotatably connected to the fixing frame 25. A first driving component 15, which is a stepper motor, is fixed on the fixing frame 25 to drive the rotating rod 21 to rotate. The speed of the rotating blades 19 can be controlled by adjusting the speed of the stepper motor. A live bait bin 12 for storing live fish and shrimp and a feed bin 29 for storing feed are fixed on the fixing frame 25. Both the live bait bin 12 and the feed bin 29 are rectangular troughs with openings at the top. A first discharge port 28 is provided on one side of the live bait bin 12, and a second discharge port 32 is provided on one side of the feed bin 29. Both the first discharge port 28 and the second discharge port 32 are located away from the feeding hopper 20, allowing the live bait and feed to better fill the entire live bait bin 12 and feed bin 29. Adding water to the live bait bin also allows the live bait to survive for a longer period. Pushing devices for propelling the live bait and feed are installed on the live bait bin 12 and feed bin 29, respectively. A water inlet pipe 3 connected to the water inlet pipe 4 is fixed to the feeding hopper 20. A water inlet switch 2 is installed on the water inlet pipe 3; the water inlet switch 2 is a water inlet valve. A discharge pipe 23 connected to the water inlet pipe 4 is fixed to the bottom of the feeding hopper 20. A switch 22 for controlling the opening and closing of the discharge pipe 23 is installed on the discharge pipe 23; the switch 22 is a butterfly valve. A feeding pipe 24 for adding feed to the rearing tank is connected to the side wall of the feeding pipe 23. The feeding pipe 24 is inclined downwards in a direction away from the feeding pipe 23. A control component for controlling the connection and disconnection between the feeding pipe 24 and the feeding pipe 23 is fixed on the feeding pipe 24. This allows the mixed live bait and feed to be directly injected into the rearing tank through the feeding pipe 24, reducing the amount of feed falling off the live bait and ensuring the efficiency of feeding training for mandarin fish fry.

[0034] The feeding device includes a feeding plate 11 that slides between the live bait bin 12 and the feed bin 29. The feeding plate 11 is a rectangular plate. Two feeding cylinders 10 are fixed on the feeding hopper 20 to push the two feeding plates 11 to slide. A first guide plate 13 is fixed at the bottom of the live bait bin 12. The first guide plate 13 extends upward along the direction close to the first discharge port 28. A second guide plate 31 is fixed at the bottom of the feed bin 29. The second guide plate 31 extends upward along the direction close to the second discharge port 32. Under the action of the feeding plate 11, live bait or feed can be pushed out from the first discharge port 28 and the second discharge port 32 located at the top. The feeding cylinders 10 drive the addition of live bait and feed, making it easier to push them out.

[0035] A rotating plate 18 is rotatably connected to the top of the feeding hopper 20. A control component 42, which is a control cylinder, is fixed on the feeding hopper 20 to control the rotation of the rotating plate 18. A weighing device 17 is installed on the rotating plate 18, and a weighing hopper 16 is fixed on the weighing device 17. When live bait or feed is added to the weighing hopper 16, the weighing device 17 is used to weigh the required live bait and feed, and then the rotating plate 18 is rotated in conjunction with the control cylinder to add the live bait and feed into the mixing chamber 1, thereby improving the accuracy of adding live bait and feed. A guide hopper 14 is fixed on the feeding hopper 20. The guide hopper 14 is conical and has a guide cavity 30 extending vertically through it. The upper side of the guide cavity 30 is used to receive the live bait and feed pushed out by the first discharge port 28 and the second discharge port 32. The bottom opening of the guide cavity 30 is located on the upper side of the weighing hopper 16, so that the live bait and feed can be injected into the weighing hopper 16 more conveniently.

[0036] The control assembly includes a control slider 35 slidably connected within the feeding pipe 24. A connecting cavity 38 is formed on the side wall of the control slider 35, with its opening facing the feeding hopper 20. The connecting cavity 38 extends through the side of the control slider 35 away from the feeding pipe 23. A second driving component 37, a second driving cylinder, is fixed on the feeding pipe 24 to drive the movement of the control slider 35. A connecting strip 36 is provided on the side of the control slider 35 away from the feeding hopper 20. A sliding elongated hole is formed on the side wall of the feeding pipe 24 to engage with the connecting strip 36. The closed sliding field of the control slider 35 side wall prevents liquid leakage. The second driving component 37 pushes the connecting strip 36 to control the slider 35. The side of the control slider 35 near the feeding pipe 23 is arc-shaped. When the control slider 35 moves away from the feeding pipe 24, it closes the feeding pipe 23. Simultaneously, the connecting cavity 38 connects the feeding pipe 24 and the feeding pipe 23, allowing the second-stage live bait and feed mixture to be discharged into the rearing tank.

[0037] The water inlet pipe 4 includes a pressurizing pipe 6 and a discharge pipe 9. A booster pump 5 is fixed on the pressurizing pipe 6. The water inlet pipe 3 is connected to the pressurizing pipe 6, which allows the water to flow more quickly and better stimulate the mandarin fish in the rearing pond, improving the feeding effect of the mandarin fish fry. A suction seat 8 is fixed between the pressurizing pipe 6 and the discharge pipe 9. The pressurizing pipe 6 is inserted into the suction seat 8. The discharge pipe 9 is coaxial with the pressurizing pipe 6. A suction chamber 7 is formed around the periphery of the pressurizing pipe 6. The suction chamber 7 is annular and is connected to the feed pipe 23, which allows for better extraction of live bait and feed.

[0038] A disinfection seat 33 is fixed on the feeding hopper 20. The disinfection seat 33 has a disinfection chamber for holding disinfectant, which is salt. A discharge port 34 is located on one side of the disinfection chamber, its opening opposite to the upper side of the feeding chamber 30. The disinfectant discharged through the discharge port 34 is weighed by a weighing device 17. A pusher plate 27 is fixed inside the disinfection chamber. A third driving component 26, a third driving cylinder, is installed inside the disinfection chamber to drive the pusher plate 27. The quantitative movement of the third driving component 26 allows salt to be quantitatively added into the feeding hopper 20.

[0039] Example 2

[0040] Reference Figure 5 The difference between this embodiment and Embodiment 1 is that a rotating seat 40 is rotatably connected to the bottom of the stirring chamber 1. The rotating seat 40 is annular and coaxially arranged with the stirring chamber 1. A first driving member 15 is used to drive the rotating seat 40 to rotate. A rotating blade 19 is fixed inside the rotating seat 40 and is tilted to one side away from the rotating seat 40. The tilting direction of the rotating blade 19 is opposite to the rotation direction of the rotating blade 19. A buffer rubber 41 is fixed to the side of the rotating blade 19 away from the tilting direction. The buffer rubber 41 is made of rubber material. The side of the buffer rubber 41 away from the rotating blade 19 is formed with an agitation groove. The agitation groove is set away from the rotating seat 40 and away from the rotating blade 19, so that the agitation groove can drive the water in the mixing chamber 1 to rotate fully. After the water has rotated fully, the live bait and feed are put into the mixing chamber 1, so that the rotating water can fully stun the live bait and achieve the purpose of mixing the feed. When the bait or feed is poured in, the rotation speed of the rotating blade 19 is reduced, which can reduce the damage to the live bait and achieve a certain mixing capacity, improving the effect and convenience of mixing live bait and feed.

[0041] Feeding training methods for mandarin fish fry at all stages include the following steps:

[0042] S1; In the first stage of feeding, live bait is pushed quantitatively by the feeding device to the weighing device 17. After the weight is determined, it is injected into the mixing chamber 1. Water is injected into the breeding pond through the water supply pipe 3. At the same time, a certain amount of salt is added to the mixing chamber 1 to disinfect the live bait.

[0043] S2, the first stage of mixing, the live bait and water are fully mixed by rotating blade 19. After mixing, the mixture is added into the water inlet pipe 4 through the feed pipe 23. Under the impact of the water flow, the mandarin fish fry can be stimulated to eat the live bait better, thus achieving the first stage of feeding training.

[0044] S3; In the second stage of feeding, live bait and feed are pushed quantitatively to the weighing device 17 through the feeding device. After weighing, they are added to the mixing chamber 1. According to the acclimatization time of the mandarin fish fry, the amount of feed is gradually increased while the amount of live bait is reduced at the same time. A small amount of flowing water is injected into the breeding pond through the water pipe 3. At the same time, a certain amount of salt is added to the mixing chamber 1 to disinfect the live bait.

[0045] S4; The second stage of mixing involves rotating the blades 19 to adhere the feed to the live bait, forming a structure that allows the feed to be used directly during the subsequent feeding process of the mandarin fish fry. This enables the mandarin fish fry to adapt to the feed more efficiently and improves the efficiency of feeding. The mixed material is then injected into the rearing pond through the feeding pipe 24. At this time, the water inlet pipe 4 continues to inject water into the rearing pond, but the injection is done separately. This not only satisfies the need to stimulate the mandarin fish fry but also reduces the amount of feed that is separated from the live bait, thereby increasing the amount of feed consumed by the mandarin fish fry.

[0046] S5; The third stage of feeding: Based on the feeding situation of the mandarin fish, the third stage of feeding is carried out with pure feed. The feed is weighed and added into the mixing chamber 1. Water is injected into the breeding pond through the water pipe 3. At the same time, a certain amount of salt is added into the mixing chamber 1 to disinfect the live bait.

[0047] S6; The third stage of mixing involves rotating blades 19 to form a liquid feed within the mixing chamber 1, which is then added to the feeding tank through the water inlet pipe 4.

[0048] The advantages of this application are as follows: In all three stages, the water flow within the inlet pipe 4 stimulates the predatory instincts of the mandarin fish, increasing their willingness to feed on treated live bait and ensuring their feed intake and growth during the critical domestication period. In the first stage, stunning the live bait prevents it from swimming excessively after feeding, thus interfering with the mandarin fish's feeding and reducing the difficulty of hunting. This helps the mandarin fish adapt to the artificial feeding rhythm more quickly, accelerating the domestication process from live bait to pre-prepared feed and improving domestication efficiency. In the second stage, attaching the feed to the live bait allows the mandarin fish to consume the feed while eating the live bait, enabling the fry to better adapt to the feed and facilitating an efficient transition to pure pre-prepared feed in the later third stage.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
