Description

Technical Field

[0001] This invention belongs to the field of fish fry breeding technology, and specifically relates to a fish fry breeding box device for ornamental fish fry breeding. Background Technology

[0002] Ornamental fish are fish with bright colors or unique shapes that are valued for their ornamental qualities. They are distributed all over the world and there are no fewer than thousands of species. Some live in freshwater, some live in seawater, some come from temperate regions, some come from tropical regions, some are known for their bright colors, some are known for their strange shapes, and some are known for their rarity and value. Ornamental fish fry require extremely high precision in feeding, uniformity of feed distribution, and water quality control during breeding. Due to their small mouths, weak feeding ability, and rapid growth rate, overfeeding can easily lead to feed residue decay, causing excessive levels of ammonia nitrogen and nitrite, resulting in enteritis, hypoxia, or even mass mortality in the fry. Insufficient feeding can lead to uneven growth and low survival rates. However, traditional methods of feeding ornamental fish fry rely on manual, timed, and quantitative feeding, which makes it difficult to control the amount of feed and the feeding area is relatively concentrated. This can easily cause the microparticle feed to scatter and sink to the bottom, making it difficult for the ornamental fish fry to eat and resulting in insufficient food intake. Therefore, we need to propose a fry rearing box device for ornamental fish fry breeding. Summary of the Invention

[0003] The purpose of this invention is to provide a fish fry rearing box device for ornamental fish. This device includes a feed storage mechanism above the rearing box for pre-storing various feeds, and a mixing mechanism below the storage mechanism for mixing the different feeds. A feeding mechanism then evenly distributes the feed into the rearing box, ensuring the ornamental fish can feed uniformly. Simultaneously, an aeration mechanism at the bottom of the rearing box provides oxygen while slowing the sinking rate of the feed, thus ensuring the ornamental fish have sufficient time to feed and improving their survival rate. This addresses the problems mentioned in the background section. To address the above problems, the present invention provides a fish fry rearing box device for ornamental fish fry breeding, comprising: A breeding box and a mounting frame installed above the breeding box. The mounting frame is equipped with a feed storage mechanism for pre-storing different feeds. The lower end of the feed storage mechanism is connected to a mixing mechanism located below the mounting frame. A feeding mechanism connected to the mixing mechanism is installed above the breeding box. The feeding mechanism evenly feeds the feed that has been mixed by the mixing mechanism into the breeding box.

[0004] Furthermore, the feeding mechanism includes two sets of feeding pipes installed at the upper end of the inner cavity of the breeding box, and a feeding auger is rotatably installed in both sets of feeding pipes. One end of each set of feeding augers is provided with a synchronization component for transmission. The shaft end of one set of feeding augers passes through the breeding box and is driven by a second motor. The upper outer sides of the two sets of feeding pipes are connected to a distribution pipe for mixed feed to enter.

[0005] Furthermore, the synchronization component includes two sets of synchronization pulleys and a synchronization belt. The two sets of synchronization pulleys are fixedly connected to one end of the two sets of feeding augers, and the synchronization belt is located on the outside of the two sets of synchronization pulleys.

[0006] Furthermore, multiple sets of discharge holes are provided at the lower outer end of both sets of feeding pipes, and the multiple sets of discharge holes are arranged at equal intervals, with each set of discharge holes having multiple discharge holes.

[0007] Furthermore, the feed storage mechanism includes multiple sets of feed boxes mounted on a mounting frame, and each set of feed boxes is provided with a connecting valve pipe at the lower end that communicates with the mixing mechanism, and each set of feed boxes is fitted with a feed cover at the upper end.

[0008] Furthermore, the mixing mechanism includes a mixing tank connected to multiple sets of connecting valve pipes. The inner cavity of the mixing tank is rotatably provided with a rotating shaft, and the upper end of the rotating shaft passes through the mixing tank and is driven by a first motor. The lower end of the rotating shaft is fixedly connected to multiple sets of stirring blades. The lower end of the mixing tank is integrally formed with a guide cone bucket connected to the upper end of the distributing pipe.

[0009] Furthermore, an isolation mechanism is installed at the bottom of the inner cavity of the breeding box, an aeration mechanism is provided on the outside of the breeding box, and a controller electrically connected to the aeration mechanism is installed on one side of the breeding box.

[0010] Furthermore, the aeration mechanism includes a return pipe inserted into the lower end of the side of the breeding tank adjacent to the controller. A filter is installed at one end of the return pipe, and the outlet end of the filter is connected to a gas-liquid mixing pipe. One end of the gas-liquid mixing pipe is connected to a water pump installed on one side of the breeding tank. The outlet end of the water pump is connected to a square pipe located in the inner cavity of the breeding tank, and multiple sets of nozzles are provided on one side of the square pipe.

[0011] Furthermore, the aeration mechanism also includes an oxygen supply pump, which is equipped with an air pipe connected to the gas-liquid mixing pipe, and a one-way valve is provided on the return pipe, the gas-liquid mixing pipe and the air pipe.

[0012] Furthermore, the isolation mechanism includes two sets of support beams and an isolation mesh plate. The two sets of support beams are fixedly connected to the lower ends of both sides of the inner cavity of the breeding box. The isolation mesh plate is set on the upper surface of the two sets of support beams, and multiple sets of positioning bolts that are bolted to the support beams are inserted into the isolation mesh plate.

[0013] The beneficial effects of this invention are: This invention utilizes the coordination between a rearing box, a mounting frame, a feed storage mechanism, a mixing mechanism, and a feeding mechanism. The feed storage mechanism can pre-store different types of feed, thus avoiding the need for manual scattering of multiple feeds each time the fish are fed. At the same time, the mixing mechanism mixes the different feeds evenly, and the feeding mechanism scatters the feed into the rearing box, ensuring that the feed is evenly distributed and that the ornamental fish fry can eat evenly. This invention utilizes the cooperation between an aeration mechanism and an isolation mechanism. The aeration mechanism introduces oxygen-containing gas into the bottom of the breeding tank, causing the oxygen to rise from the bottom up. This creates a certain buoyancy effect on the falling feed, ensuring adequate oxygen supply for the ornamental fish. Furthermore, during aeration, the bottom water circulates, guiding and filtering the deposited feces, thus ensuring clear water quality and providing a good growth environment for ornamental fish fry.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0019] This invention provides a fish fry rearing box device for ornamental fish fry breeding, including a rearing box 1 and a mounting frame 2 installed above the rearing box 1. The rearing box 1 is made of transparent float glass, which facilitates observation of the rearing of ornamental fish fry. The mounting frame 2 is a stainless steel frame that is fastened to the upper sides of the rearing box 1 by expansion bolts. The mounting frame 2 is equipped with a feed storage mechanism 3 for pre-storing different feeds. The feed storage mechanism 3 is composed of multiple cylinders with a volume greater than 3L. The lower end of the feed storage mechanism 3 is connected to a mixing mechanism 4 located below the mounting frame 2. The mixing mechanism 4 has a volume greater than 5L, which can ensure the uniformity of the mixing. A feeding mechanism 5 connected to the mixing mechanism 4 is installed above the rearing box 1. The feeding mechanism 5 evenly feeds the feed mixed by the mixing mechanism 4 into the rearing box 1.

[0020] In this embodiment, the feeding mechanism 5 includes two sets of feeding pipes 51 installed at the upper end of the inner cavity of the breeding box 1, and feeding augers 53 are rotatably installed in both sets of feeding pipes 51. One end of each set of feeding augers 53 is provided with a synchronization component for transmission. The shaft end of one set of feeding augers 53 passes through the breeding box 1 and is driven by the second motor 54. The upper outer side of the two sets of feeding pipes 51 is connected to a distribution pipe 52 for mixed feed to enter. With the cooperation of two sets of feeding pipes 51 and feeding auger 53, it can be ensured that the feed is evenly distributed in the breeding tank 1, avoiding too much or too little feed in some areas, so that the fish fry can feed evenly when they are scattered. At the same time, the speed of feeding auger 53 is adjustable, and the feeding speed can be flexibly adjusted according to the size of the fish fry and the amount of feed they consume, thereby reducing feed waste. In addition, both the feeding pipe 51 and the distributing pipe 52 are made of food-grade materials to prevent feed from being contaminated and to ensure the safety of fish fry farming. The second motor 54 is equipped with a reducer (existing technology, not shown in the figure) to reduce the speed while increasing the torque, ensuring smooth feeding and preventing feed from being difficult to discharge due to excessive speed.

[0021] Secondly, the synchronization assembly includes two sets of synchronization pulleys 55 and a synchronization belt 56. The two sets of synchronization pulleys 55 are fixedly connected to one end of the two sets of feeding augers 53. The synchronization belt 56 is located on the outside of the two sets of synchronization pulleys 55. The synchronization pulleys 55 have 20 teeth and are galvanized. The synchronization belt 56 is made of neoprene rubber with embedded fiberglass rope. The synchronization pulleys 55 are connected to the shaft ends of the feeding augers 53 by a key. A lock nut is provided at the connection to prevent the synchronization pulleys 55 from loosening. The two sets of synchronous pulleys 55 enable the two sets of feeding augers 53 to rotate synchronously under the action of the synchronous belt 56, thereby achieving synchronous rotation of the two sets of feeding augers 53 and ensuring that the feed can be discharged synchronously from the discharge holes 57 on the two sets of feeding pipes 51.

[0022] Specifically, multiple sets of discharge holes 57 are provided at the lower outer end of both sets of feeding pipes 51, and the multiple sets of discharge holes 57 are arranged at equal intervals, with each set of discharge holes 57 having multiple discharge holes. Multiple sets of equally spaced feeding holes 57 further improve the uniformity of feed delivery, ensuring that fish fry in all areas of the breeding tank 1 can obtain feed. At the same time, the feeding holes 57 are arranged in a rectangular array, and the diameter of the feeding holes 57 is greater than 3mm, which can avoid the problem of blockage or excessive feeding caused by the mismatch between feed particle size and hole size.

[0023] Furthermore, the feed storage mechanism 3 includes multiple sets of feed boxes 31 installed on the mounting frame 2, and each set of feed boxes 31 is provided with a connecting valve pipe 33 connected to the mixing mechanism 4 at its lower end, and each set of feed boxes 31 is fitted with a feed cover 32 at its upper end. Multiple feed boxes 31 can store different types and sizes of fish fry feed to meet the nutritional needs of fish fry at different growth stages, eliminating the need for frequent feed changes and improving the convenience of aquaculture. At the same time, the feed cover 32 has ventilation holes (not shown in the figure) to prevent the feed from getting damp and clumping, ensure air circulation inside the feed box 31, and extend the shelf life of the feed. The connecting valve pipe 33 is equipped with a solenoid valve, model 2W-160-15, voltage 220V, flow rate 0.5-2L / min. The switch and flow rate can be controlled by the controller 6, which can accurately control the amount of each feed, thereby achieving proportional mixing of different feeds, ensuring balanced nutrition for fish fry, and reducing errors from manual control.

[0024] It is worth noting that the mixing mechanism 4 includes a mixing tank 41 connected to multiple sets of connecting valve pipes 33. The inner cavity of the mixing tank 41 is rotatably provided with a rotating shaft 43, and the upper end of the rotating shaft 43 passes through the mixing tank 41 and is driven by the first motor 44. The lower end of the rotating shaft 43 is fixedly connected to multiple sets of stirring blades 45. The lower end of the mixing tank 41 is integrally formed with a guide cone 42 connected to the upper end of the distribution pipe 52. The lower end of the guide cone 42 is connected to the upper end of the distribution pipe 52 by a quick-connect flange, with a built-in food-grade silicone sealing ring to prevent leakage. An electric slide valve is installed at the connection, and its opening and closing are controlled by the controller 6, so that the material is fed in after mixing. The mixing tank 41 is made of food-grade stainless steel, which is corrosion-resistant, easy to clean, and avoids feed contamination. A transparent observation window (not shown in the figure) is provided on its outside to facilitate observation of the feed mixing and timely adjustment of the mixing time. At the same time, the guide cone 42 can ensure that the uniformly mixed feed flows completely into the distribution pipe 52, avoiding feed accumulation and waste at the bottom of the mixing tank 41. The mixing blades 45 work in conjunction with the rotating shaft 43, and are driven by the first motor 44 to achieve thorough mixing of the feed. The mixing speed is adjustable to adapt to the mixing requirements of different feeds, ensuring uniform nutrition and providing balanced nutrition for the fish fry.

[0025] Specifically, an isolation mechanism 8 is installed at the bottom of the inner cavity of the breeding box 1, an aeration mechanism 7 is installed on the outside of the breeding box 1, and a controller 6 electrically connected to the aeration mechanism 7 is installed on one side of the breeding box 1. The isolation mechanism 8 can separate the fish fry from the uneaten feed and feces at the bottom of the breeding tank 1, reducing the disease caused by the fish fry accidentally eating uneaten feed. At the same time, it is easy to clean up uneaten feed and feces, and improve the water quality maintenance capacity. The aeration mechanism 7 replenishes oxygen in the water in the breeding tank 1 to meet the oxygen demand of the fish fry during the growth process and reduce the mortality rate of the fish fry due to lack of oxygen. The controller 6 enables automated control of the device, allowing precise setting of various operating parameters without the need for real-time manual monitoring, thus improving aquaculture efficiency and reducing labor costs. At the same time, it can flexibly adjust operating parameters according to the growth of fish fry to meet the needs of fish fry at different growth stages.

[0026] It is worth noting that the controller 6 is a touch-screen programmable controller (PLC) with functions of timed feeding, quantitative proportioning, automatic mixing, and linkage aeration. A material level sensor is installed in the feed box 31. When the material level is low, the controller will sound an audible and visual alarm. A material detection sensor is installed in the mixing tank 41. Feeding is prohibited when there is no material to avoid idling.

[0027] Furthermore, the aeration mechanism 7 includes a return pipe 71 inserted into the lower end of the side adjacent to the controller 6 of the breeding tank 1. A filter 72 is installed at one end of the return pipe 71. The filter 72 is model CF-1000, with a filtration accuracy of 5μm. It is made of plastic and equipped with removable and washable filter cotton. The outlet end of the filter 72 is connected to a gas-liquid mixing pipe 73. One end of the gas-liquid mixing pipe 73 is connected to a water pump 74 installed on one side of the breeding tank 1. The outlet end of the water pump 74 is connected to a square pipe 75 located in the inner cavity of the breeding tank 1. Multiple sets of nozzles 76 are provided on one side of the square pipe 75. By using the return pipe 71 in conjunction with the filter 72, the water in the breeding tank 1 can be circulated and filtered to remove impurities such as uneaten feed and feces, maintain water quality, and reduce fish fry diseases caused by water pollution. The water pump 74 drives the water circulation, and together with the square pipe 75 and multiple sets of nozzles 76, oxygen is distributed at the bottom of the breeding tank 1, so that oxygen rises after passing through the isolation mechanism 8, avoiding local water hypoxia. The filter 72 is designed with removable and washable filter cotton, which facilitates regular cleaning, thereby reducing maintenance costs and extending the service life of the filter 72. At the same time, the rising oxygen in the circulating water can promote the even distribution of feed and reduce feed accumulation.

[0028] Meanwhile, the aeration mechanism 7 also includes an oxygen supply pump 77, which is equipped with an air pipe 78 connected to the gas-liquid mixing pipe 73. The air pipe 78 is made of silicone and has good flexibility. One-way valves are installed on the return pipe 71, the gas-liquid mixing pipe 73 and the air pipe 78. The one-way valves are made of copper, which is corrosion resistant and has good sealing performance, thus extending the service life of the aeration mechanism 7 and ensuring the stable operation of the aeration system. The oxygen pump 77 provides sufficient air to the gas-liquid mixing pipe 73, allowing the water to replenish oxygen during circulation and further increasing the oxygen content in the water to meet the oxygen requirements of high-density aquaculture of ornamental fish fry. Meanwhile, the one-way valve effectively prevents backflow of water and air, avoids oxygen leakage, and improves oxygen utilization.

[0029] Preferably, the isolation mechanism 8 includes two sets of support beams 81 and an isolation mesh plate 82. The two sets of support beams 81 are fixedly connected to the lower ends of both sides of the inner cavity of the breeding box 1. The support beams 81 are welded to the inner wall of the breeding box 1, and the welded joints are polished. The isolation mesh plate 82 is set on the upper surface of the two sets of support beams 81. The mesh size of the isolation mesh plate 82 is 1mm×1mm, which is suitable for the size of fish fry and prevents fish fry from falling from the mesh to the bottom. The surface is passivated. Multiple sets of positioning bolts 83 that are bolted to the support beams 81 are inserted into the isolation mesh plate 82. The support beam 81 provides stable support for the isolation net plate 82. The mesh size of the isolation net plate 82 is precisely adapted to the size of the fish fry, which can separate the fish fry from the uneaten feed and feces at the bottom without restricting the movement of the fish fry. At the same time, the passivation treatment improves the rust resistance of the isolation net plate 82 and is suitable for humid breeding environments. The positioning bolts 83 facilitate the installation and disassembly of the isolation net plate 82, and make it convenient to regularly clean the uneaten feed and feces under the isolation net plate 82 to maintain a clean breeding environment.

[0030] When in use, different types and sizes of fish fry feed are placed into multiple feed boxes 31 of the feed storage mechanism 3, the feed cover 32 is closed, the feeding ratio and feeding time of each feed are set by the controller 6, the controller 6 controls the solenoid valve connected to the valve pipe 33 at the lower end of the feed box 31 to open, and feed is sent into the mixing tank 41 of the mixing mechanism 4 according to the set ratio. Then the first motor 44 starts, and drives the rotating shaft 43 and stirring blade 45 to rotate through the reducer. The stirring blade 45 fully mixes the various feeds in the mixing tank 41. The operator can observe the mixing situation through the transparent observation window of the mixing tank 41. After the mixture is evenly mixed, the controller 6 controls the electric slide valve (not shown in the figure) of the guide cone 42 at the lower end of the mixing tank 41 and the distribution pipe 52 to open. The mixed feed flows into the distribution pipe 52 of the feeding mechanism 5 and then is divided into two sets of feeding pipes 51. At this time, the second motor 54 starts and drives one set of feeding augers 53 to rotate through the reducer. At the same time, the other set of feeding augers 53 rotates synchronously through the synchronization component. The feeding augers 53 push the mixed feed in the feeding pipe 51 to both ends. The feed falls evenly into the breeding box 1 through multiple sets of feeding holes 57 at the lower end of the feeding pipe 51, so as to achieve uniform feeding of fish fry. The speed of the feeding augers 53 can be adjusted by the controller 6 to adapt to the feeding needs of different fish fry. During the feeding process, the aeration mechanism 7 works continuously, and the water pump 74 starts, drawing water from the rearing tank 1 into the filter 72 through the return pipe 71. The filter 72 filters out uneaten feed and feces from the water. The filtered water enters the gas-liquid mixing pipe 73. At the same time, the oxygen supply pump 77 starts, sending air into the gas-liquid mixing pipe 73 through the air pipe 78. The mixing spiral in the gas-liquid mixing pipe 73 mixes the air and water thoroughly, forming oxygen-rich water. The oxygen-rich water is pumped by the water pump 74 to the square pipe 75, and then evenly sprayed to the bottom of the rearing tank 1 through multiple sets of nozzles 76, providing sufficient oxygen for the fry. At the same time, some of the gas in the sprayed water will rise through the isolation mechanism 8, thereby slowing down the falling rate of the feed and increasing the feeding time for the fry. During the breeding process, the isolation mechanism 8 at the bottom of the breeding box 1 separates the fish fry from the uneaten feed and feces at the bottom, preventing the fish fry from accidentally eating the uneaten feed and causing diseases. The positioning bolts 83 can be removed periodically, and the isolation mesh plate 82 can be taken off to clean the uneaten feed and feces attached to the isolation mesh plate 82, so as to maintain water quality and ensure that the fish fry grow in a suitable environment and improve the survival rate of the fish fry.
