Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a surface feed feeding device for mussel aquaculture. Background Art

[0002] In the mussel aquaculture industry, feeding is one of the key links to ensure the healthy growth and high yield of mussels. However, the existing surface feed feeding devices have significant deficiencies in practical applications, especially in terms of feed distribution uniformity. These problems not only affect the feeding efficiency of mussels, but also pose challenges to the overall aquaculture effect.

[0003] At present, most of the surface feed feeding devices used in mussel aquaculture on the market adopt a simple spreading or spraying method. Although this method can spread the feed on the water surface to a certain extent, it is difficult to achieve uniform coverage. Due to the lack of precise control mechanism, these devices cannot flexibly adjust the feeding amount and range according to the specific conditions of the breeding pond (such as area, shape, water depth, etc.), resulting in excessive feed in some areas and insufficient feed in other places. This uneven distribution makes it easy for mussels close to the feeding point to obtain more food, while individuals far away from the feeding point may grow slowly or even die due to food shortage, ultimately affecting the yield and quality of the entire farm.

[0004] Existing feeding devices often ignore the impact of water flow. In open water or aquaculture environments with strong water flow, once the feed is put into the water, it will be quickly carried away and fail to stay effectively in the target area for mussels to eat. This situation not only wastes precious feed resources, but may also lead to local eutrophication, which in turn affects water quality and the ecological environment. For those mussels located downstream of the water flow, they may not be able to access enough feed at all, which further exacerbates growth differences and unfair competition.

[0005] Another significant problem is that existing feeding equipment is not adaptable enough to different sized feed particles. Mussels need feed of different particle sizes at different growth stages to meet their changing nutritional needs. However, many traditional equipment does not take this into account, and may become clogged when handling fine particles, while being unable to ensure uniform distribution when feeding larger particles. This not only limits the range of feed options, but is also not conducive to refined management, reducing the overall benefits of aquaculture.

[0006] Existing feeding devices do not perform well in dealing with complex weather conditions. For example, in strong winds, the feed may be blown away and deviate from the intended feeding area; in rainy days or when the waves are large, the fluctuations in the water surface will affect the feeding accuracy, making it difficult for the feed to reach the designated location accurately. These problems increase the difficulty of operation and may lead to unnecessary losses.

[0007] Therefore, how to provide a surface feed feeding device for mussel aquaculture is a problem that technicians in this field urgently need to solve. Summary of the invention

[0047] Furthermore, the supply cover 10 is opened, mussel feed is poured into the storage area, the device is placed on the sea surface of the mussel farm in the shallow sea area, the hull 1 is started, and the operation of the power component 2, the floating and sinking component 3 and the negative pressure generating component 6 is controlled by the controller 12; the signal receiver 13 is used to receive the transmitted electrical signal, and the direction control panel 14 is used to control the running direction of the hull 1.

[0048] The device of the present invention is remotely driven and remotely releases mussel feed, which is in powder form. Mussels are filter-feeding animals whose main food sources are plankton, microalgae and organic particles in the water. They obtain nutrition by naturally filtering micro feed particles in the water.

[0049] The power motor 2.1 is started, and the rotation shaft of the power motor 2.1 drives the power bevel gear 2.2 to rotate, and the rotation of the power bevel gear 2.2 drives the rotation of the power cylinder 2.3, and the rotation of the power cylinder 2.3 drives the rotation of the power blades 2.4, and the rotation of the power blades 2.4 pushes the hull 1 forward.

[0050] The centrifugal pump 3.3 and the electric switch valve 3.5 are started. The centrifugal pump 3.3 draws seawater into the first liquid pipe 3.2 and the floating and sinking area through the second liquid pipe 3.4. The centrifugal pump 3.3 then draws seawater in the floating and sinking area through the first liquid pipe 3.2 and discharges it overseas from the second liquid pipe 3.4 to control the draft of the hull 1 in the sea and maintain the stable driving of the hull 1 on the sea.

[0051] The high-speed blower 6.2 is started, and the high-speed blower 6.2 draws outside air through the air inlet pipe 8, and sends it into the negative pressure generating pipe 6.1 through the air supply pipe 6.3. The high-speed air fluid of the air supply pipe 6.3 flows into the negative pressure generating pipe 6.1, and the negative pressure generating pipe 6.1 is located at the negative pressure connecting pipe 5.3 to generate a negative pressure area. The negative pressure area also generates negative pressure in the negative pressure feeding pipe 5.1, the negative pressure connecting pipe 5.2 and the negative pressure connecting pipe 5.3. The feeding valve core 7.3 moves along the support rod 7.1. Slide downward, compress the tension spring 7.4, and the mouth of the negative pressure feeding pipe 5.1 generates negative pressure to absorb the powdered feed in the storage area. The powdered feed enters the negative pressure feeding pipe 5.1, the negative pressure connecting pipe 5.2 and the negative pressure docking pipe 5.3 in sequence, and then enters the negative pressure generating pipe 6.1 through the negative pressure docking pipe 5.3. The powdered feed enters the air pipe 6.4 under the high-speed air flow, and then the air pipe 6.4 docks with the power cylinder 2.3, and the flowing powdered feed enters the power cylinder 2.3.

[0052] The feed flowing inside the power cylinder 2.3 enters the discharge pipe 9.1. The rotation of the power cylinder 2.3 drives the rotation of the power cylinder 2.3. The rotation of the power cylinder 2.3 generates a certain centrifugal force. The discharge valve ball 9.3 slides along the limit pipe frame 9.2 in the opposite direction of the discharge pipe 9.1, and the discharge spring 9.5 is stretched. The high-speed air fluid and the feed also play a role in pushing open the discharge valve ball 9.3. The powder feed is dispersed from the outlet of the discharge pipe 9.1. The power fan blades 2.4 better break up the powder feed and evenly scatter it in the seawater, which is convenient for mussels to naturally filter the tiny feed particles in the water to obtain nutrition.

[0053] The rotation of the power cylinder 2.3 generates centrifugal force on the discharge valve ball 9.3, and the high-speed air fluid and feed also push the discharge valve ball 9.3 to open the discharge valve ball 9.3, so that the discharge port can be effectively leaked, so as to avoid the discharge valve ball 9.3 sealing the discharge pipe 9.1 when the hull 1 is in the sea and no feed is fed.

[0054] The present invention can accurately control the moving direction of the hull 1 and the stability of the feeding system through the coordinated work of the signal receiver 13 and the direction control board 14; the controller 12 can remotely adjust the operation of the power component 2, the floating and sinking component 3, etc., so as to achieve refined management; this control system not only improves the degree of automation, but also reduces the complexity and errors of human operation, and enhances the convenience of use of the equipment.

[0055] The combination of the power motor 2.1, the power bevel gear 2.2, the power cylinder 2.3 and the power blades 2.4 realizes efficient power transmission; in particular, the design of the power blades 2.4, in addition to driving the hull 1 forward, can also drive air flow through rotation, which helps to evenly distribute the feed powder in the water, avoid feed accumulation, and improve the uniformity and effectiveness of feed delivery; the system is cleverly and concisely designed, avoiding complex traditional propulsion methods and improving the reliability and life of the equipment.

[0056] The centrifugal pump 3.3 and the electric switch valve 3.5 in the floating and sinking component 3 achieve the stability of the hull 1 under different sea conditions by adjusting the liquid pressure between the floating and sinking baffle 3.1 and the hull 1; the floating and sinking component can automatically adjust the draft of the hull as needed, which helps to keep the hull stable in different water depths and tidal changes, thereby avoiding the tilting or imbalance of the hull, effectively reducing the risk of equipment getting wet and capsizing, and improving safety.

[0057] The negative pressure conveying component 5 absorbs the feed by forming a negative pressure area and conveys it to other parts of the hull; this design can ensure that the powdered feed is not disturbed by external airflow during the delivery process, thereby avoiding waste and loss of feed; the combination of the negative pressure generating tube 6.1 and the air feed tube 6.4 allows the feed to be evenly and quickly delivered to the seawater with the airflow as the carrier without causing condensation or precipitation of the feed; through this conveying system, more precise feeding control can be achieved to improve the feeding efficiency of mussels; the discharge component 9 controls the release of feed through the combined action of the centrifugal force of the discharge valve ball 9.3 and the high-speed airflow; this design ensures effective sealing when there is no feeding demand through the cooperation of the discharge valve ball 9.3 and the spring to avoid feed leakage; and when feed needs to be delivered, the combined action of the high-speed airflow and the centrifugal force can quickly open the valve to ensure even delivery of feed; this system can reduce feed waste while ensuring the sealing of the hull to prevent feed leakage from polluting the environment.

[0058] Through the negative pressure conveying system, the automatic control unit and the precise mechanical structure, the present invention can automatically and accurately deliver the powdered feed into the seawater; this fully automated control method can ensure that each delivery is accurate and correct, avoiding errors caused by manual operation, while reducing the demand for manual labor and improving work efficiency; in addition, the remote control function of the device means that the equipment can be adjusted at a long distance, reducing manual intervention and improving operational flexibility.

[0059] The hull 1 and various components (such as the feeding unit, the power component 2 and the floating and sinking component 3) are modularly fixedly installed; such a design allows the various components to be flexibly configured according to different needs, and has strong adaptability and scalability; in addition, the separation of the storage area and the functional area between the ship warehouse body 1.2 and the layered plate 4 ensures the high efficiency of the storage and transportation of the feed, and avoids the feed from getting damp or deteriorating due to long-term storage.

[0060] The device uses a battery 11 as a power source, combined with an efficient power component 2 and an energy management system, which can ensure a stable energy supply during long-term operation; the battery is reasonably designed, which can not only provide stable power support, but also optimize the operating efficiency of the power motor 2.1, extend its service life, and reduce energy consumption; the design meets the requirements of modern environmental protection and energy conservation, and reduces the cost of use.
