Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, specifically to a self-propelled compound feeder and a dual-purpose feeding vessel for small fish in marine crab farming ponds. Background Technology

[0002] In the marine crab farming industry, the feeding process is a crucial link affecting farming efficiency and the growth quality of marine crabs. However, current feeding methods and related equipment in marine crab farming ponds still have many technical shortcomings, making it difficult to meet the needs of large-scale and high-efficiency farming. Traditional marine crab farming ponds rely heavily on manual rowing operations. For larger ponds, manual feeding is not only labor-intensive and time-consuming, but also prone to uneven feed distribution due to differences in human operation, such as rowing speed and feeding force. In addition, feed accumulation in some areas leads to waste, and it can also pollute the water quality or cause insufficient feed in some areas, resulting in uneven feeding of marine crabs, affecting the uniformity of growth, and even reducing the survival rate. To solve these problems, existing technologies have provided some solutions. For example, US11892833B2 discloses an agricultural amphibious bait delivery boat that can move between ponds and its control method. The agricultural amphibious bait delivery boat of this technology includes a hull. One end of the hull is fixed with a feeding device, and the other end of the hull is fixed with a propulsion device. For example, the prior art KR102713732B1 discloses an unmanned feed supply vessel for fish farms. This technology enables operators to distribute feed while moving in the fish farm, improving the convenience and efficiency of feed supply. However, existing feeding methods and equipment still have room for improvement in terms of efficiency and environmental friendliness. Summary of the Invention

[0003] The purpose of this invention is to provide a self-propelled feeding vessel for both compound feed and small fish in marine crab farming ponds. This solves the problems of low efficiency and uneven material distribution caused by manual feeding. Furthermore, this invention can achieve dual feeding of feed or small fish, thus reducing equipment costs.

[0004] To solve the aforementioned technical problems, this invention specifically provides the following technical solution: a self-propelled feeding vessel for both formulated feed and small fish in marine crab farming ponds, comprising two opposing hulls connected by a first float. One end of the first float has a storage tank, and the other end has a feeding assembly. The feeding assembly includes a feeding box with an upper opening, and a discharge pipe arrayed at the bottom of the feeding box, communicating with the interior of the feeding box. The bottom of the feeding box is connected to the first float via a fixing frame. The discharge pipe and the bottom of the feeding box are vertically aligned, with openings at both ends, allowing material inside the feeding box to be discharged through the discharge pipe. This invention, by setting up two opposing hulls and the upper first float to form a stable load-bearing structure, stably supports the storage tank and the feeding assembly, preventing the hull from capsizing. Furthermore, the storage tank and the feeding assembly are located at opposite ends of the first float, ensuring stable buoyancy and preventing excessive tilting of the hull on the water surface. Among them, the feeding component has an open top feeding box for easy material addition, and the bottom is connected to the first floating plate through a fixed frame to ensure that the feeding box does not shake when the ship is moving or discharging. The discharge pipes arranged in the array are vertically connected to the bottom of the feeding box and open at both ends, which not only ensures that the compound feed falls smoothly, but also avoids blockage by small fish and lumps of material. At the same time, it solves the problem of uneven feeding in traditional single-point feeding, allowing all seawater crabs in the aquaculture pond to feed efficiently.

[0005] According to one embodiment of the present invention, a spiral shaft corresponding to the number of discharge pipes is provided inside the feeding box. The end of the spiral shaft is placed inside the discharge pipe, and a drive motor coaxially connected to the upper end of the spiral shaft is provided. The spiral shaft is formed by blades spirally arranged around the side of the optical axis.

[0006] This invention uses a feeding box as a material storage and conveying carrier. The number of spiral shafts inside the box corresponds one-to-one with the number of discharge pipes, and the end of the spiral shaft extends into the discharge pipe, avoiding uneven feeding caused by multiple pipes sharing a single shaft. Simultaneously, the spiral shaft adopts a side-mounted spiral blade design, which, compared to the traditional straight rod structure, creates a uniform thrust on the compound feed or small fish in the feeding box. This loosens and pushes out clumps of compound feed, while preventing small fish from getting stuck at the discharge pipe inlet due to compression, thus solving the problem of conveying blockages for both materials. Furthermore, the upper end of the spiral shaft is coaxially connected to the drive motor, ensuring consistent material discharge from each discharge pipe and further expanding and homogenizing the feeding coverage area. At the same time, the active spiral feeding replaces traditional gravity feeding; even if the remaining material in the feeding box is small, the spiral blades can push the material completely to the discharge pipe, reducing material residue in the feeding box and improving material utilization.

[0007] According to one embodiment of the present invention, the upper end of the feeding box is provided with a first connecting rod connected to its inner wall. An array of mounting bases is arranged on the first connecting rod, and the bottom of the mounting bases is connected to a drive motor. The upper end of the feeding box is connected to the inner wall via the first connecting rod, avoiding the occupation of the material storage and flow space below the feeding box. This ensures that formulated feed or small fish can smoothly fall into the spiral shaft area without material accumulation caused by structural obstruction. Simultaneously, the mounting bases provide rigid fixation to the drive motor, counteracting vibrations generated during motor operation and preventing long-term motor shaking that could lead to component loosening. Stable motor operation ensures uniform spiral shaft speed, thereby guaranteeing consistent material discharge from each discharge pipe.

[0008] According to one embodiment of the present invention, a baffle connected to one side of the feeding box is provided. When feed or small fish are discharged from the discharge pipe, the baffle can prevent the material from being scattered outwards in the feeding direction due to airflow, water surface fluctuations, or slight wind caused by the movement of the ship, so that the material is concentrated and falls into the target feeding area of ​​the aquaculture pond. Furthermore, when the ship moves along the feeding direction by the propeller, the baffle can share some of the impact of the travel resistance on the feeding box, preventing the feeding box from loosening at the connection due to long-term stress, and indirectly ensuring the coaxial stability of the discharge pipe and the screw shaft.

[0009] According to one embodiment of the present invention, a flow guiding assembly is provided on one side of the discharge pipe. The flow guiding assembly includes first flow guiding plates disposed on both sides of the discharge port of the discharge pipe. The distance between two adjacent first flow guiding plates on the discharge pipe is greater than the distance at the end away from the discharge pipe. A first assembly rod is connected above the two first flow guiding plates by a connecting frame. The first assembly rod is connected to the fixing frame by a clamp.

[0010] The gradual design, where the distance between the two first guide plates and the adjacent discharge pipes is greater than the distance at the end furthest from the discharge pipe, allows the water flow to flow smoothly along the surface of the guide plates. When the water flow comes into contact with the first guide plates, it will spread along the plate body from the wide opening to the narrow opening. This prevents the formation of eddies at the discharge outlet of the discharge pipe and also prevents the reverse impact force on the falling material. When feed or small fish are discharged from the discharge pipe, the water flow in the aquaculture pond or the water flow generated by the movement of the boat can easily wash the material away from the target feeding area. The barriers formed by the first guide plate on both sides can prevent the water flow from directly impacting the material, providing a stable channel for the material to fall and avoiding the imbalance of material distribution due to water flow interference. In addition, the gradually changing spacing structure of the first guide plate can gently guide the material falling vertically from the discharge pipe to both sides. After the material enters the wide opening of the two guide plates, it will gradually spread outward as the spacing between the plates decreases. With the array layout of the discharge pipe, the material that was originally concentrated directly below the discharge pipe can be spread to a wider lateral range, solving the problem of material accumulating below the hull and having no material in the edge area under the traditional non-guide structure.

[0011] Meanwhile, the two first guide vanes are securely connected to the first assembly rod via a connecting frame. The first assembly rod is then connected to the fixed frame via a clamp, and the fixed frame is connected to the bottom of the feeding box. This is used to offset the impact of vibrations or water surface fluctuations on the guide vane during the ship's movement, and to prevent the first guide vane from shifting and causing guide vane failure.

[0012] According to one embodiment of the present invention, a swingable second guide plate is provided on the outer side of the first guide plate, and a side plate is provided above the two first guide plates, the side plate being connected to a first assembly rod. A spring is sleeved on the first assembly rod. The swingable second guide plate on the outer side of the first guide plate can dynamically adjust its angle according to the water flow in the aquaculture pond or the water flow generated by the movement of the boat. When the water flow impacts, the second guide plate swings accordingly, which can disperse the impact force of the water flow and prevent the water flow from excessively impacting the first guide plate, causing the material to deviate. At the same time, it can help guide the material to diffuse over a wider range. The side plate above the two first guide plates is connected to the first assembly rod, which can strengthen the overall rigidity of the first guide plate and prevent it from deforming due to long-term water flow impact or the weight of the material.

[0013] According to one embodiment of the present invention, a propeller is provided at the stern of the hull. The propeller, located at the stern, can directly transmit forward power to the hull, driving the two opposing hulls to move synchronously. This avoids yaw caused by unilateral power, achieving full coverage of the aquaculture pond and solving the problems of low efficiency and limited coverage of traditional manual rowing for feeding.

[0014] According to one embodiment of the present invention, a rotatable sail is provided on the first float. The sail on the first float is rotatably connected, and its angle can be flexibly adjusted according to the real-time wind direction of the aquaculture pond. When there is a suitable wind direction, the sail rotates to a windward position, which can use the wind power to provide auxiliary propulsion for the hull, reduce the energy consumption of the propeller, and reduce the operating cost of aquaculture. At the same time, when the hull deviates from its course due to water flow fluctuations or slight eccentricity of the propeller, the direction of force can be adjusted by rotating the sail, which can help correct the hull's trajectory.

[0015] According to one embodiment of the present invention, the two hulls are connected by a support rod, and the support rods are connected by an auxiliary rod. The support rod is provided with a rotating shaft passing through the first float plate, and the rotating shaft is connected to the sail plate.

[0016] The two hulls are connected by a support rod, which can effectively resist the impact of the water flow in the aquaculture pond or the lateral force when the hulls are moving, and prevent the two hulls from shifting or tilting. This ensures the horizontal attitude of the first floating board above. At the same time, the rotating shaft on the support rod passes through the first floating board and is connected to the sail, preventing the rotating shaft from shifting due to wind or vibration. This ensures that the sail can rotate accurately and smoothly around the rotating shaft, making it easy to adjust the windward angle according to the real-time wind direction.

[0017] According to one embodiment of the present invention, a collector is provided on the first buoy. The collector is used to collect parameters such as water temperature and pH value in the water area during the movement of the feeding vessel, as well as to collect water samples. When the vessel is driven by the propeller, the collector can dynamically collect water parameters in different feeding areas, avoiding the limitations of traditional fixed-point sampling or manual sampling, and realizing real-time acquisition of water temperature and pH value and water sample collection throughout the aquaculture pond. In addition, the water temperature and pH value obtained by the collector are directly related to the feeding needs of marine crabs. For example, when the water temperature is too low, the feeding desire of marine crabs decreases, and farmers can adjust the feeding amount or timing based on the data.

[0018] Compared with existing technologies, the beneficial effects of the present invention are as follows: The self-propelled feeder for both compound feed and small fish in the marine crab farming pond of the present invention can achieve dual feeding of compound feed and small fish without the need to replace equipment, thus reducing the investment cost of farming equipment. In addition, the device of the present invention can achieve feeding coverage of the entire farming pond. Furthermore, the present invention solves the problem of blockage of lumpy materials by actively feeding with a spiral shaft, and guides the material to spread evenly with the flow guiding component, avoiding the accumulation or omission of materials in traditional feeding. The present invention provides a high-efficiency, low-cost, uniform, stable and precise feeding device for marine crab farming. Attached Figure Description

Detailed Implementation

[0022] 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. 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.

[0023] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1: As shown in the attached figure Figure 1 -Appendix Figure 6As shown, the self-propelled feeding vessel for both formulated feed and small fish in a marine crab farming pond includes two opposing hulls 11. The two hulls 11 are connected at the top by a first float 10. One end of the first float 10 is equipped with a storage tank 13, and the other end is equipped with a feeding assembly 30. The feeding assembly 30 includes a feeding box 31 with an open top. The bottom of the feeding box 31 is arranged with a discharge pipe 37 that communicates with the inside of the feeding box 31. The bottom of the feeding box 31 is connected to the first float 10 by a fixing frame 33. The discharge pipe 37 and the bottom of the feeding box 31 are vertically arranged, and both ends of the discharge pipe 37 are open, allowing the material inside the feeding box 31 to be discharged from the inside of the feeding box 31 through the discharge pipe 37. This invention utilizes two opposing hulls 11 and a first floating plate 10 above to form a stable load-bearing structure, which stably supports the storage tank 13 and the feeding component 30, preventing the hull from capsizing. Furthermore, the storage tank 13 and the feeding component 30 are located at opposite ends of the first floating plate 10, ensuring stable buoyancy and preventing excessive tilting of the hull on the water surface. The feeding component 30 features an open-top feeding box 31 for easy material addition, and its bottom is connected to the first floating plate 10 via a fixing frame 33, ensuring that the feeding box 31 does not sway during hull movement or material discharge. The arrayed discharge pipes 37 are vertically connected to the bottom of the feeding box 31 and open at both ends, ensuring smooth flow of formulated feed and preventing blockage by small fish or lumps of material. This also solves the problem of uneven feeding in traditional single-point feeding, allowing all seawater crabs in the aquaculture pond to feed efficiently.

[0025] The feeding box 31 is equipped with a spiral shaft 38 corresponding to the number of discharge pipes 37. The end of the spiral shaft 38 is placed inside the discharge pipe 37, and the upper end of the spiral shaft 38 is equipped with a drive motor 36 coaxially connected to it. The spiral shaft 38 is formed by spirally arranging blades on the side of the optical axis.

[0026] This invention uses the feeding box 31 as a material storage and conveying carrier. The number of spiral shafts 38 inside the feeding box 31 corresponds one-to-one with the number of discharge pipes 37, and the end of the spiral shaft 38 extends into the discharge pipe 37, avoiding uneven feeding caused by multiple pipes sharing a single shaft. Simultaneously, the spiral shaft 38 adopts a side-mounted spiral blade design, which, compared to the traditional straight rod structure, can generate a uniform thrust on the compound feed or small fish in the feeding box 31. This not only loosens and pushes out clumps of compound feed but also prevents small fish from getting stuck at the inlet of the discharge pipe 37 due to compression, solving the problem of conveying blockages for both materials. Furthermore, the upper end of the spiral shaft 38 is coaxially connected to the drive motor 36, ensuring consistent material discharge from each discharge pipe 37 and further expanding and homogenizing the feeding coverage area. At the same time, the active spiral feeding replaces traditional gravity feeding; even if the remaining material in the feeding box 31 is small, the spiral blades can push the material completely to the discharge pipe 37, reducing material residue in the feeding box 31 and improving material utilization.

[0027] The upper end of the feeding box 31 is equipped with a first connecting rod 35 connected to its inner wall. An array of mounting bases 32 are arranged on the first connecting rod 35, and the bottom of the mounting bases 32 is connected to the drive motor 36. The connection between the upper end of the feeding box 31 and the inner wall via the first connecting rod 35 avoids occupying the material storage and flow space below the feeding box 31, ensuring that formulated feed or small fish can fall smoothly into the spiral shaft 38 area without material accumulation due to structural obstruction. Simultaneously, the mounting bases 32 rigidly fix the drive motor 36, counteracting vibrations generated during motor operation and preventing long-term motor shaking from causing component loosening. Stable motor operation ensures uniform rotational speed of the spiral shaft 38, thereby guaranteeing consistent material discharge from each discharge pipe 37.

[0028] A baffle 34 is provided on one side of the feeding box 31. When feed or small fish are discharged from the discharge pipe 37, the baffle 34 can prevent the material from being scattered outwards in the feeding direction due to airflow, water surface fluctuations, or slight wind caused by the movement of the ship, so that the material is concentrated and falls into the target feeding area of ​​the aquaculture pond. Furthermore, when the hull 11 moves along the feeding direction by the propeller 14, the baffle 34 can share some of the impact of the travel resistance on the feeding box 31, preventing the feeding box 31 from loosening at the connection due to long-term stress, and indirectly ensuring the stability of the coaxial fit between the discharge pipe 37 and the spiral shaft 38.

[0029] A flow guiding component 40 is provided on one side of the discharge pipe 37. The flow guiding component 40 includes first flow guiding plates 42 disposed on both sides of the discharge port of the discharge pipe 37. The distance between the two first flow guiding plates 42 adjacent to the discharge pipe 37 is greater than the distance at the end away from the discharge pipe 37. A first assembly rod 41 is connected above the two first flow guiding plates 42 by a connecting frame 44. The first assembly rod 41 is connected to the fixing frame 33 by a clamping plate 39.

[0030] In the flow guiding assembly 40, two first flow guiding plates 42 are fixedly connected to the first assembly rod 41 through the connecting frame 44. The first assembly rod 41 is then tightly connected to the fixing frame 33 through the clamp 39. The fixing frame 33 directly forms a rigid support structure with the bottom of the feeding box 31 and the first float 10. This can resist the impact of the natural water flow in the aquaculture pond or the water flow generated by the movement of the hull 11, and prevent the first flow guiding plates 42 from shifting or shaking due to the force of the water flow. The gradual change in the distance between the two first flow guiding plates 42 and the adjacent discharge pipes 37 is greater than the distance at the end away from the discharge pipe 37, which allows the water flow to flow smoothly along the surface of the flow guiding plate. When the water flow comes into contact with the first flow guiding plate 42, it will spread along the plate from the wide opening to the narrow opening. This will not form a vortex at the discharge outlet of the discharge pipe 37, nor will it generate a reverse impact force on the falling material. When feed or small fish are discharged from the discharge pipe 37, the water flow in the aquaculture pond or the water flow driven by the movement of the hull can easily wash the material away from the target feeding area. The barriers formed by the first guide plate 42 on both sides can block the water flow from directly impacting the material, providing a stable channel for the material to fall and avoiding the imbalance of material distribution due to water flow interference. In addition, the gradually changing spacing structure of the first guide plate 42 can gently guide the material falling vertically from the discharge pipe 37 to both sides. After the material enters the wide opening of the two guide plates, it will gradually spread outward as the spacing between the plates decreases. With the array arrangement of the discharge pipe 37, the material that was originally concentrated directly below the discharge pipe 37 can be spread to a wider lateral range, solving the problem of material accumulating under the hull and having no material in the edge area under the traditional non-guide structure.

[0031] Meanwhile, the two first guide plates 42 are securely connected to the first assembly rod 41 through the connecting frame 44. The first assembly rod 41 is then connected to the fixing frame 33 through the clamp 39. The fixing frame 33 is connected to the bottom of the feeding box 31 to offset the impact of vibration or water surface fluctuation on the guide assembly 40 during the movement of the hull 11, and to prevent the first guide plate 42 from shifting and causing the guide to fail.

[0032] A swingable second guide plate 43 is provided on the outer side of the first guide plate 42. A side plate 45 is provided above the two first guide plates 42, and the side plate 45 is connected to the first assembly rod 41. A spring is sleeved on the first assembly rod 41. The swingable second guide plate 43 on the outer side of the first guide plate 42 can dynamically adjust its angle with the water flow generated by the aquaculture pond or the movement of the hull 11. When the water flow impacts, the second guide plate 43 swings accordingly, which can disperse the impact force of the water flow and avoid excessive impact of the water flow on the first guide plate 42, causing the material to deviate. At the same time, it can help guide the material to spread to a wider range. The side plate 45 above the two first guide plates 42 is connected to the first assembly rod 41, which can strengthen the overall rigidity of the first guide plate 42 and prevent it from deforming due to long-term water flow impact or the weight of the material.

[0033] A propeller 14 is provided at the end of the hull 11. The propeller 14 is located at the end of the hull 11 and can directly transmit forward power to the hull 11, driving the two oppositely set hulls 11 to move synchronously, avoiding hull yaw caused by unilateral power, realizing full coverage of the aquaculture pond, and solving the problems of low efficiency and limited coverage of traditional manual rowing feeding.

[0034] The first float 10 is equipped with a rotatable sail 20. The sail 20 on the first float 1 is rotatably connected and can be flexibly adjusted according to the real-time wind direction in the aquaculture pond. When there is a suitable wind direction, the sail 20 rotates to the windward position, which can use the wind power to provide auxiliary propulsion for the hull 11, reduce the energy consumption of the propeller 14, and reduce the aquaculture operating cost. At the same time, when the hull 11 deviates from its course due to water flow fluctuations or slight off-center loading of the propeller 14, the direction of force can be adjusted by rotating the sail 20, which can help correct the trajectory of the hull 11.

[0035] The two hulls 11 are connected by a support rod 15, and the support rods 15 are connected by an auxiliary rod. The support rod 15 is provided with a rotating shaft that passes through the first float 10 and is connected to the sail 20.

[0036] The two hulls 11 are connected by a support rod 15, which can effectively resist the impact of the water flow in the aquaculture pond or the lateral force when the hulls 11 are moving, and prevent the two hulls 11 from shifting or tilting, thereby ensuring the horizontal attitude of the first floating plate 10 above. At the same time, the rotating shaft on the support rod 15 passes through the first floating plate 10 and is connected to the sail 20, preventing the rotating shaft from shifting due to wind or vibration, and ensuring that the sail 20 can rotate accurately and smoothly around the rotating shaft, which makes it easy to adjust the windward angle according to the real-time wind direction.

[0037] A data collector 12 is installed on the first float 10. The data collector 12 is used to collect parameters such as water temperature and pH value in the water area during the movement of the feeding vessel, as well as to collect water samples. When the vessel 11 is driven by the propeller 14, the data collector 12 can dynamically collect water parameters in different feeding areas, avoiding the limitations of traditional fixed-point sampling or manual sampling, and realizing real-time acquisition of water temperature and pH value and water sample collection throughout the aquaculture pond. In addition, the water temperature and pH value obtained by the data collector 12 are directly related to the feeding needs of sea crabs. For example, when the water temperature is too low, the sea crabs' appetite decreases, and farmers can adjust the feeding amount or timing based on the data.

[0038] Example 2: See appendix Figure 7-8As shown, based on embodiment 1, this embodiment provides a further solution in which at least one flow-slowing component 50 is provided between the two hulls 11. The flow-slowing component 50 includes a rotating shaft 52 connected to the two hulls 11. A connecting sleeve 53 coaxial with the rotating shaft 52 is provided on the rotating shaft 52. A blade 51 is arranged around the connecting sleeve 53. The pivot 52 between the two hulls 11 directly connects the hulls, and together with the connecting sleeve 53 and the blade 51, it forms a flow-slowing component 50. The pivot 52 not only provides the installation foundation for the flow-slowing structure, but also further strengthens the lateral connection between the hulls 11, preventing the hulls 11 from shifting due to water flow impact or power fluctuations of the propeller 14. At the same time, the connecting sleeve 53 and the pivot 52 are coaxially set, allowing the surrounding blade 51 to rotate with the water flow. When the hull 11 moves forward under the drive of the propeller 14, the water flow on both sides of the hull or the rearward water flow generated by the propeller 14 impacts the blade 51. The blade 51 rotates around the pivot 52 through the connecting sleeve 53, decomposing the strong water flow into a gentle eddy, avoiding the rapid current from disturbing the sea crabs, especially in the juvenile stage, preventing them from refusing to eat due to stress. Moreover, the water environment after the flow slows down is more stable, and the compound feed or small fish discharged from the discharge pipe 37 is less likely to be scattered or deviated by the water flow, and can fall accurately to the target feeding area, ensuring the uniformity of feeding.
