Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine culture engineering, in particular to a seawater fry adaptive domestication feeding device and method. BACKGROUND

[0002] Seawater fry domestication is a key link in the marine aquaculture industry chain, directly determining the survival rate, growth uniformity and subsequent breeding benefits of fry. Newly hatched seawater fry is fragile, and has strict requirements for bait type, feeding environment and feeding rhythm, and needs to be gradually transitioned from natural plankton bait to artificial compound feed through scientific domestication, while adapting to artificial breeding environment. However, in the conveying process of the feed from the storage box to the feeding box of the existing device, the feed in the feeding box is prone to form local accumulation, and when discharged, it is prone to form a mass of feeding phenomenon, causing uneven feeding of fry, which can easily cause some areas of fry to cause stress reaction due to overeating, and some areas to cause growth lag due to insufficient feed, seriously affecting the domestication uniformity. For this reason, there are mechanical feeding equipment technologies, such as the prior art KR1020250063357A, which discloses an automatic feeding device and method for shrimp field, which utilizes data supplied from a networked server while an unmanned aerial vehicle that lands on a site floating on a fish farm autonomously flies in the sky of the fish farm, and feeds the shrimp bred in the fish farm according to a set time and the activity of the shrimp. This technology focuses on intelligent feeding. Also, the prior art WO2025175594A1 discloses a fry cultivation device and its cultivation method, which can feed regularly and quantitatively, avoid concentrated feeding inconvenience, provide a safe and sufficient feed growth environment for small-sized fry, and reduce fry size differences. However, the existing technology still has room for improvement in terms of feed preservation and feeding effect during the domestication feeding process. SUMMARY

[0003] The purpose of the present application is to provide a seawater fry adaptive domestication feeding device and method, which solves the problems of unstable storage, uneven feeding, poor baiting effect, weak environmental adaptability and low automation degree in the existing seawater fry domestication feeding process.

[0004] To solve the above technical problems, the present application specifically provides the following technical solutions: a seawater fry seed adaptive domestication feeding device and method, comprising a rack, a storage tank is arranged on one side of the rack, the bottom of the storage tank is provided with a feeding tank in communication therewith, the storage tank is installed in an inclined manner on the rack, and the rack is provided with a connecting frame connected with the storage tank, and the outlet of the feeding tank is arranged at the bottom. The present application provides a bearing base through the rack, and the storage tank is fixed to the rack by the connecting frame. The storage tank is designed to be installed in an inclined manner, and the internal feed can be guided to slide to the bottom by gravity, so that the feed is prevented from accumulating in the corners of the tank, uniform and continuous feeding is achieved, the problem of intermittent feeding or uneven amount of traditional horizontal storage tank is solved, and further, the feeding tank in communication with the bottom of the storage tank is provided, the bottom outlet of the feeding tank is used to receive the inclined transported feed, and the retention and local accumulation of the feed in the feeding tank are reduced.

[0005] According to an embodiment of the present application, an aeration assembly is arranged on the side of the feeding tank, the aeration assembly comprises an aeration pipe arranged on the side of the feeding tank, the end of the aeration pipe is provided with a multi-way valve and connected with a second pipe body, a first pump body is arranged on the rack, and the first pump body is connected with the second pipe body through a third pipe body. The aeration pipe is provided with a check valve to prevent external water from flowing back into the first pipe body or the second pipe body. The first pump body serves as a power source, and gas is transported to the second pipe body through the third pipe body, and then distributed by the multi-way valve at the end of the aeration pipe, and then released to the water body by the aeration pipe on the side of the feeding tank, so as to form continuous water flow disturbance, simulate the dynamic environment of natural bait, attract fry to gather in the feeding area, improve the feeding enthusiasm of the fry to artificial feed, and shorten the domestication period. At the same time, the check valve arranged in the aeration pipe can effectively block the external water from flowing back into the first pipe body or the second pipe body, so as to avoid the seawater from eroding the core components such as the first pump body.

[0006] According to an embodiment of the present application, a second pump body in communication with the inside of the feeding tank is arranged on one side of the feeding tank, and the second pump body is connected with the multi-way valve at the end of the aeration pipe through a first pipe body. The second pump body on one side of the feeding tank is in communication with the inside of the tank and connected with the multi-way valve at the end of the aeration pipe through the first pipe body, so as to form a double-pump gas supply scheme with the first pump body, control the aeration intensity and range of the aeration pipe by adjusting the output power of the two pumps, adapt to the needs of fry at different growth stages for water flow disturbance, and improve the food-seeking pertinence. At the same time, the gas transported by the second pump body directly acts on the inside of the feeding tank, forms continuous air flow disturbance, loosens the locally accumulated feed in the tank, further breaks the feed agglomeration with the feeding structure, enhances the dispersibility during feeding, and completely avoids the problem of uneven feeding caused by group feeding. In addition, the gas flow is more stable after the double-pump gas supply is integrated through the multi-way valve, so as to ensure that the gas outlet of the aeration pipe is uniform, and the fry gathers more concentratedly.

[0007] According to an embodiment of the present application, a lamp body is arranged above the aeration pipe. The lamp body above the aeration pipe utilizes the phototaxis of marine fry, and forms a double feeding stimulus of light signal and water flow disturbance with the aeration flow of the aeration pipe, thereby shortening the acclimatization period of the transition from natural bait to artificial feed. At the same time, the stable visual marker provided by the lamp body can still accurately locate the feeding area when the water body is turbid or the natural light is insufficient, thereby avoiding the waste caused by the difficulty of fry foraging after the feed is put in.

[0008] According to an embodiment of the present application, the bottom of the feeding box is provided with a floating assembly, the floating assembly comprises a float, the float is rotatably connected with a screen plate on both sides, the screen plate is connected with a light rod, and the end of the light rod is connected with the aeration pipe or the second pipe body through a rope. The float can automatically float up and down with the fluctuation of the water level of the breeding water body, and through the connection of the rope at the end of the light rod with the aeration pipe or the second pipe body, the aeration assembly is synchronously adjusted in height, so that the outlet of the feeding box, the aeration area of the aeration pipe and the illumination area of the lamp body are always matched with the water level, thereby solving the problem of deviation of the feeding position caused by tides or water change. The screen plates rotatably connected on both sides of the float can be flexibly rotated with the water flow, which can not only buffer the impact of water body fluctuation on the device and ensure the stability of the overall structure, but also assist in diffusing the feed put in, thereby avoiding the local accumulation and sinking to the bottom and improving the utilization rate of the feed.

[0009] According to an embodiment of the present application, the same side of the float is provided with at least two screen plates arranged in an upper and lower interval, and the adjacent screen plates are connected through a light rod. The screen plates arranged in an upper and lower interval can form layered buffering to the water body, and weaken the impact of the water flow layer by layer, thereby reducing the disturbance of the fluctuation to the outlet of the feeding box and the position of the aeration pipe, and ensuring the accuracy of feeding and aeration. At the same time, the multi-layer screen plates can intercept and diffuse the feed discharged from the feeding box in layers, prevent the feed from being concentrated and sinking to the bottom or floating and being lost, and enable the fry in different water layers to obtain the bait, thereby improving the uniformity of feeding and the utilization rate of the feed. The light rod connecting and fixing the screen plates can avoid the random rotation and deviation of the screen plates, and ensure the continuous and stable buffering and diffusion effect.

[0010] According to an embodiment of the present application, an electric control valve is arranged at the bottom outlet of the feeding box. The electric control valve at the bottom outlet of the feeding box is used to realize the feeding of the feed, and through the data of the position sensor and the humidity sensor built in the storage box, the feeding amount can be accurately controlled according to the feeding demand of the fry in different growth stages and the state of the feed.

[0011] According to an embodiment of the present application, at least one side of the storage box is provided with a light-transmitting plate. The light-transmitting plate is used to realize the visual monitoring of the state of the feed in the box, and the breeder can directly observe the amount of the feed without opening the storage box. In addition, the light-transmitting plate can also assist in observing the sliding track of the feed, judging whether there is a problem such as corner accumulation and poor feeding, and ensuring uniform feeding. Furthermore, the light-transmitting plate can introduce natural light, and inhibit the breeding of microorganisms in the storage box to a certain extent.

[0012] According to an embodiment of the present application, a cabinet is arranged on the rack. The storage tank is provided with a sensor, such as a humidity sensor, for detecting the humidity of the storage environment, and a position sensor for detecting the amount of feed.

[0013] The method based on the seawater fry seed adaptability domestication feeding device is as follows: Step 1), fix the rack in the breeding area, stabilize the inclined storage tank through the connecting frame, add artificial feed corresponding to the growth stage into the storage tank, and observe the feed distribution state through the light transmission plate. Turn on the control system in the cabinet, preset parameters according to the fry size, set the feed supplement warning value combined with the position sensor threshold value, set the upper limit of the storage environment humidity (such as ≤65%) according to the humidity sensor, and match the opening and closing frequency of the electric control valve, the first motor speed and the running intensity of the aeration assembly according to the fry stage.

[0014] Step 2), the humidity sensor and the position sensor built-in the storage tank continuously collect data and transmit them to the cabinet. If the humidity exceeds the standard or the amount of feed is lower than the warning value, the system triggers a reminder, and the breeder reviews through the light transmission plate and timely supplements dry feed. At the same time, observe the sliding state of the feed through the slow flow element through the light transmission plate, if there is accumulation, check the cooperation of the sliding plate and the chute to ensure that the feed flows uniformly to the feeding tank.

[0015] Step 3), - minutes before the preset feeding time, the cabinet control opens the lamp body, and starts the first pump body and the second pump body. The first pump body supplies gas through the third pipe body and the second pipe body, and the second pump body transports gas from the feeding tank through the first pipe body. After the double-path gas is integrated by the multi-way valve, it is released by the aeration pipe to form water flow disturbance, combined with the light signal to guide the fry to gather in the feeding area.

[0016] Step 4), the feed in the storage tank slides under the action of gravity, is gradually buffered and dispersed by the first swing plate and the second swing plate of the slow flow element, to avoid particle breakage; after the feed enters the feeding tank, the first motor drives the rotating shaft to rotate the rotating disc, and the first rotating plate and the second rotating plate of the rotating plate group disperse the feed again to avoid lump accumulation.

[0017] Step 5), the cabinet controls the opening and closing of the electric control valve according to the preset parameters, and the dispersed feed is uniformly fed through the outlet; the float of the floating assembly floats up and down with the water level fluctuation, and adjusts the height of the aeration pipe synchronously through the rope body to ensure that the aeration, illumination and feeding area coincide; the multi-layer net plate on both sides of the float rotates with the water flow to further stratify and diffuse the feed, adapting to different water layer fry feeding.

[0018] Step 6), after the feeding is completed, the cabinet successively closes the lamp body, the double pump body, the first motor and the electric control valve.

[0019] Regularly clean the feed residue inside the feeding box and check the sealing of the aeration pipe check valve and the elasticity of the spring; adjust the opening and closing of the electric control valve, the aeration intensity, and the on-time of the lamp according to the growth of the fry and the feeding feedback to optimize the acclimatization effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The storage box of the present invention is installed at an angle through a connecting frame. With the help of the sliding groove and movable flow buffer, first swing plate and second swing plate arranged on the inner wall along the material sliding direction, the feed can be prevented from accumulating and breaking by gravity and buffer structure. Moreover, the light-transmitting plate on at least one side can be used to directly observe the feed status. In the feeding process, the internal structure of the feeding box can completely break up clumps of feed. Furthermore, the first pump and second pump of the aeration component form a dual-pump aeration scheme to induce feeding and improve the feeding enthusiasm of fish fry. The solution of the present invention can reduce the cost of manual supervision and improve the survival rate, uniformity of growth and domestication efficiency of fish fry.

The present application will be described in detail below with reference to the drawings and in combination with the embodiments. EMBODIMENT

[0026] As shown in the drawings Figure 1 -attached Figure 6 The present application specifically provides the following technical solutions: a seawater fry adaptive domestication feeding device and method, comprising a rack 11, one side of the rack 11 is provided with a storage box 20, the bottom of the storage box 20 is provided with a feeding box 50 in communication therewith, the storage box 20 is installed in an inclined manner on the rack 11, and the rack 11 is provided with a connecting frame 12 connected with the storage box 20, and the outlet of the feeding box 50 is arranged at the bottom. The present application provides a bearing basis through the rack 11, and the storage box 20 is fixed to the rack 11 by the connecting frame 12. The storage box 20 is designed to be installed in an inclined manner, so that the internal feed can be guided to slide to the bottom by gravity, thereby avoiding the accumulation of feed in the corners of the box, achieving uniform and continuous feeding, solving the problem of intermittent feeding or uneven feeding of the traditional horizontal storage box, and further, the feeding box 50 in communication with the bottom of the storage box 20 is provided, and the bottom outlet of the feeding box 50 is used to receive the inclinedly conveyed feed, thereby reducing the retention and local accumulation of the feed in the feeding box 50.

[0027] The feeding tank 50 is provided with an aeration assembly 30 on the side. The aeration assembly 30 includes an aeration pipe 35 arranged on the side of the feeding tank 50. The aeration pipe 35 is provided with a multi-way valve at the end and connected to a second pipe body 33. A first pump body 31 is arranged on the rack 11 and connected to the second pipe body 33 through a third pipe body 36. The aeration pipe 35 is provided with a check valve to prevent external water from flowing back into the first pipe body 32 or the second pipe body 33. The first pump body 31 serves as a power source and sends gas to the second pipe body 33 through the third pipe body 36. The gas is distributed by the multi-way valve at the end of the aeration pipe 35 and released to the water body by the aeration pipe 35 on the side of the feeding tank 50, forming a continuous water flow disturbance, simulating the dynamic environment of natural bait, attracting fry to gather in the feeding area, improving the feeding enthusiasm of artificial feed, and shortening the acclimation period. At the same time, the check valve in the aeration pipe 35 can effectively block the external water from flowing back into the first pipe body 32 or the second pipe body 33, avoiding seawater erosion of the core components such as the first pump body 31.

[0028] A second pump body 37 is arranged on one side of the feeding tank 50 and communicates with the inside of the feeding tank 50. The second pump body 37 is connected to the multi-way valve at the end of the aeration pipe 35 through the first pipe body 32. The second pump body 37 on one side of the feeding tank 50 communicates with the inside of the feeding tank 50 and connects the multi-way valve at the end of the aeration pipe 35 through the first pipe body 32, which can form a double-pump gas supply scheme with the first pump body 31. The aeration intensity and range of the aeration pipe 35 can be controlled by adjusting the output power of the two pumps to adapt to the needs of fry at different growth stages for water flow disturbance and improve the targeted feeding attraction. At the same time, the gas delivered by the second pump body 37 directly acts on the inside of the feeding tank 50, forming a continuous air flow disturbance, which can loosen the locally accumulated feed in the tank, further breaking the feed agglomeration with the feeding structure, enhancing the dispersibility during feeding, and completely avoiding the problem of uneven feeding caused by mass feeding.

[0029] A lamp body 34 is arranged above the aeration pipe 35. The lamp body 34 above the aeration pipe 35 utilizes the phototaxis of marine fry and forms a double feeding attraction stimulus of light signal and water flow disturbance with the aeration water flow of the aeration pipe 35, shortening the acclimation period of natural bait to artificial feed. At the same time, the stable visual marker provided by the lamp body 34 can still accurately locate the feeding area when the water body is turbid or the natural light is insufficient, avoiding the waste caused by the difficulty of fry foraging after feeding.

[0030] The bottom of the feeding box 50 is provided with a floating assembly 40, which includes a float 41, the two sides of the float 41 are rotatably connected with a mesh plate 43, the mesh plate 43 is connected with a light rod 44, and the end of the light rod 44 is connected with the aeration pipe 35 or the second pipe body 33 through a rope 42. The float 41 can automatically float up and down with the fluctuation of the water level of the breeding water body. Through the connection of the rope 42 at the end of the light rod 44 and the aeration pipe 35 or the second pipe body 33, the aeration assembly 30 is synchronously adjusted in height, so that the outlet of the feeding box 50, the aeration area of the aeration pipe 35 and the illumination area of the lamp body 34 are always matched with the water level, solving the problem of deviation of the feeding position caused by tides or water change. The mesh plate 43 rotatably connected on both sides of the float 41 can be flexibly rotated with the water flow, which can not only buffer the impact of water body fluctuation on the device to ensure the stability of the overall structure, but also assist in diffusing the feed to avoid local accumulation and sinking to the bottom and improve the utilization rate of the feed.

[0031] The same side of the float 41 is provided with at least two mesh plates 43 arranged in an upper and lower interval, and the adjacent mesh plates 43 are connected through the light rod 44. The upper and lower interval mesh plates 43 can form a layered buffer to the water body, and gradually weaken the impact of the water flow, reduce the disturbance of the fluctuation to the outlet of the feeding box 50 and the position of the aeration pipe 35, and ensure the accuracy of feeding and aeration. At the same time, the multi-layer mesh plate 43 can layer the feed discharged from the feeding box 50 and diffuse it to prevent the feed from concentrating and sinking to the bottom or floating and losing, so that the fry in different water layers can obtain the feed, and the uniformity of feeding and the utilization rate of the feed are improved. The light rod 44 penetrates and fixes the mesh plate 43 to avoid its arbitrary rotation and deviation, ensuring the continuous and stable buffering and diffusion effect.

[0032] The bottom outlet of the feeding box 50 is provided with an electric control valve 54. The electric control valve 54 at the bottom outlet of the feeding box 50 is used to realize the feeding of the feed, and through the data of the position sensor and humidity sensor built in the storage box 20, the feeding amount can be accurately controlled according to the feeding demand of the fry in different growth stages and the state of the feed.

In addition, the light-transmitting plate can also assist in observing the sliding trajectory of the feed to judge whether there is a corner accumulation, poor feeding and other problems, and ensure uniform feeding. In addition, the light-transmitting plate can introduce natural light to a certain extent to inhibit the breeding of dark-loving microorganisms in the storage box 20.
