Description

Technical Field

[0001] The invention relates to the technical field of feeding devices for fry breeding, and in particular to a feeding device with a material dividing function for fry breeding and a feeding method thereof. Background Art

[0002] Fry farming technology covers the entire process from hatching to rearing of fry, mainly including water quality management, temperature control, feed feeding, disease prevention and control, etc. Reasonable breeding technology and equipment selection can greatly improve the survival rate and growth rate of fry. Fry have a high demand for oxygen, and oxygenation equipment is required to keep the dissolved oxygen content in the water at a reasonable level; key indicators such as ammonia nitrogen, nitrite, and pH value in the water should be monitored regularly. Keep the water clean by changing the water or using water quality improvers. Fry are sensitive to temperature, and the optimal growth temperature for most fish is 20-28℃. The water temperature can be adjusted by heaters or cooling equipment.

[0003] The digestive system of fry is not fully developed yet, so it is necessary to choose feed that is easy to digest and rich in protein. Common feeds include micro-particle feed, powdered feed, floating pellet feed, etc. Fry need to be fed in small amounts and multiple times, 3-6 times a day. The feeding amount should be adjusted according to the actual feeding situation of the fry to avoid excessive feed causing water quality deterioration. The feed ratio should be adjusted according to the different growth stages of the fry. In the early stage, high-protein and micro-feed should be used as the main feed, and in the later stage, it should gradually transition to pellet feed.

[0004] Common feeding devices include manual feeders, automatic timed feeders and automatic feeder distribution; Manual feeders: suitable for small-scale breeding and feeding in the early stages of fry. Simple operation and low cost, but requires frequent manual feeding, which is inefficient. Automatic timed feeder: This device can automatically put feed into the fry pond according to the set time and frequency. Suitable for small and medium-sized farms, which can effectively reduce manual operation. Timed feeders are suitable for feeding granular feeds. Advantages: Reduce labor costs and maintain the regularity of feeding. Disadvantages: Not suitable for feeding multiple feeds or micro-powder feeds. Automatic feeder distribution: It can mix multiple feeds and feed automatically according to the nutritional needs of fry. It is usually equipped with a compartment device, which can mix different types of feeds according to the set ratio and feed them, which is suitable for medium and large farms. Advantages: Accurately control the feed ratio and is suitable for feeding multiple types of feeds. Disadvantages: High cost and requires regular maintenance.

[0005] In the process of using the existing feeding device with a feed distribution function for fry farming and the feeding method thereof, the mixing of multiple feeds is not uniform, the feed ratio is controlled by the control system to set the valve opening time, and the feeding area is small, which easily causes the feeding amount of fry to be unbalanced. On the one hand, the fry need to ensure sufficient feed to ensure healthy growth, on the other hand, too much feed will cause abnormal development of the fry and affect the local feeding area, resulting in deterioration of water quality. In view of the above situation, in order to overcome the above technical problems, the present invention designs a feeding device with a material distribution function for fry farming and a feeding method thereof, which solves the above technical problems. Summary of the invention

[0006] The technical purpose to be achieved by the present invention is to design a feeding device with a feeding function for fry farming and a feeding method thereof, to carry out a uniform feeding design for fry cultivation, to ensure the healthy growth of fry and to protect the water quality conditions of the aquaculture waters.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions: A feeding device with a feeding function for fry farming mainly includes key components such as a discharging tray, a feeding mechanism, a stirring mechanism, and a sealing assembly. These components cooperate with each other to ensure that the fry can get uniform, quantitative and proportional feed during the farming process, helping the fry to grow and develop better.

[0008] The feed tray is set at the top of the fry breeding device. Its main function is to feed different types of feed to the fry pond below in an evenly distributed manner. By accurately controlling the feed's landing point and distribution, the feed tray can effectively prevent the feed from piling up in one place, ensuring that each fry can get the right amount of feed. This even feeding method not only helps to improve the survival rate of fry, but also reduces feed waste.

[0009] The feed dispensing mechanism is installed above the dispensing tray and is responsible for storing different types of feed. Fry have different nutritional requirements at different growth stages and usually require a reasonable combination of multiple feeds. Therefore, the feed dispensing mechanism is designed with multiple storage bins to store different types of feed, such as powdered feed, granular feed, etc. The feed dispensing mechanism can mix different types of feed as needed according to the set ratio through the internal precise control system. This function ensures that fry can obtain appropriate nutrition at each growth stage and avoids the problem of uneven growth caused by improper feed ratio.

[0010] The stirring mechanism is located in the middle of the feeding mechanism and plays the role of fully mixing different feeds. The stirring mechanism controls the falling speed of each feed so that different feeds can fall in proportion within an appropriate time and mix in the discharge tray, and then be put into the fry pond. The precise control of the stirring mechanism can avoid the phenomenon of uneven mixing of feeds, thereby ensuring that the fry can evenly absorb various nutrients.

[0011] The sealing component is installed above the feed dispensing mechanism to seal and preserve the stored feed. Since feed is easily exposed to the air for a long time and is prone to moisture absorption, mold, or oxidation and deterioration, the sealing component can effectively prevent these problems from occurring and ensure that the feed remains fresh and dry during use. The design of the sealing component not only extends the storage time of the feed, but also reduces the risk of feed waste and feeding failure.

[0012] The discharging tray is composed of a discharging bottom plate and a discharging hole. The discharging bottom plate is located below the discharging tray and is designed as a larger circular structure to fit the common circular large tanks in most fry farms. This design can better cover the entire feeding area and ensure that the feed is evenly distributed. There are multiple discharging holes evenly distributed on the discharging bottom plate. The setting of these holes allows the feed to be distributed to every corner of the fry pond at a stable speed and quality, thereby avoiding the feed from being concentrated in one place. Through this uniform feeding method, it can effectively ensure that each fry can obtain sufficient nutrition to promote its healthy growth.

[0013] The material distributing mechanism comprises a material distributing sleeve, a fixing column, a material distributing partition plate, a mounting magnetic block, a material dropping port and a material distributing assembly; The material dividing sleeve is arranged on the top of the discharge plate, the fixed column is installed in the middle of the material dividing sleeve, the material dividing baffle is installed in the middle of the fixed column and the material dividing sleeve, the mounting magnetic block is arranged on the top of the fixed column, the material dropping port is opened on the bottom plate of the material dividing sleeve, and the material dividing assembly is installed in the material dropping port.

[0014] The number of the dividing baffles is usually set to 2-5, and the specific number depends on the type of feed required during the fry breeding process. An independent cavity will be formed between each dividing baffle and the dividing sleeve to accommodate different types of feed respectively. These independent cavity designs can effectively prevent the mixing of multiple feeds during storage and maintain their respective quality and freshness. Different types of feed have different preservation requirements, such as moisture-proof and oxidation-proof, so separate storage can reduce the risk of feed deterioration. Through this isolation design, the fry can obtain appropriate nutrition according to the growth stage, ensuring that the feeding of the feed is more scientific and accurate, and promoting the healthy growth of the fry.

[0015] The material distribution partitions are arranged in a circular array around the fixed column. This arrangement ensures that each feed compartment is evenly distributed in the material distribution mechanism, which is convenient for the independent storage and precise delivery of different types of feed. Each feed drop port is opened in the middle of two adjacent material distribution partitions. This design ensures that the feed can smoothly fall from each independent compartment into the discharge tray, thereby achieving uniform distribution and mixed feeding of the feed. This structural layout not only optimizes the fluidity of the feed, but also improves the working efficiency of the feeding device, ensuring that the fry are supplied with a variety of feeds in a reasonable proportion.

[0016] The material distribution assembly includes a fixed shaft and a push plate; the fixed shaft is installed in the feeding port, and the intersection of the axis extension lines of the multiple fixed shafts coincides with the center point of the fixed column; the push plate is installed in the middle of the fixed shaft, and there are four push plates, which are arranged at equal angles around the fixed shaft. The axis extension lines of the multiple fixed shafts coincide with the center point of the fixed column, which means that the movement of each push plate is symmetrical around the center, which helps to ensure that different feeds enter the discharge tray evenly from each feeding port and avoid the feed from being biased in a certain direction. The push plates are arranged at equal angles around the fixed shaft, and the four push plates can evenly push the feed in their respective compartments, so that the feed can flow out from different compartments at the same time, thereby realizing efficient mixing of multiple feeds. The push plate can accurately control the feeding speed and quantity of each feed through the rotation of the fixed shaft, ensuring the controllability of the amount of feed, thereby avoiding feed waste and improving feeding efficiency.

[0017] The stirring mechanism is composed of a rotating shaft, a push rod, a spiral blade and a vortex push plate, and the various components work in coordination to ensure that the feed is fully mixed and evenly distributed. The rotating shaft is arranged in the middle of the feeding mechanism, and is the core supporting part of the entire stirring mechanism. Its rotation drives other components to work. The push rod is located at the upper end of the rotating shaft, and is used to push the feed to fall during the feeding process. The spiral blades are installed on the main part of the rotating shaft. The spiral design of the blades helps to generate a rotational driving force during stirring, so that different types of feed can be fully stirred and mixed. The vortex push plate is located at the lower end of the rotating shaft, and the vortex effect is used to further enhance the stirring effect of the feed, ensuring that the feed has been evenly mixed before falling into the discharge tray.

[0018] The push plates are designed to be three and distributed in the stirring mechanism to provide stable thrust. The two vortex push plates are arranged in a relatively opposite manner. Such a design can effectively push the mixed feed falling in the middle to the surroundings evenly during the rotation process. Due to the special structure of the vortex push plate, the feed can be evenly diffused at a slower speed to avoid too fast or uneven delivery, thereby ensuring that the fry in the entire breeding area can obtain the right amount of feed and promote their balanced feeding.

[0019] The sealing assembly is composed of a sealing plate, a cover plate, an inner arc surface and a movable handle, etc., which is designed to effectively protect the internal feed and prevent it from being affected by the external environment. The sealing plate is located at the bottom of the sealing assembly, which plays a role of basic support and sealing to ensure that the feed is not easy to leak. The cover plate is installed above the sealing plate and fits closely with the sealing plate to form a closed space, further enhancing the sealing effect. The inner arc surface is arranged on the inner side of the sealing plate and the cover plate, and adopts an arc design, which can better fit the cover plate and enhance the sealing performance. The inner arc surface is also coated with a magnetic coating to ensure that the cover plate can be firmly adsorbed on the sealing plate when closed, preventing air from entering and water evaporation, thereby maintaining the freshness of the feed. The movable handle is installed on the surface of the cover plate, which is convenient for users to easily open and close the sealing assembly, and the operation is simple and convenient. Through this design, the sealing assembly not only improves the preservation effect of the feed, but also reduces the waste of feed caused by improper storage, providing a more reliable guarantee for fry farming.

[0020] A feeding method with a feeding function for fry farming, which is adapted to the above-mentioned feeding device with a feeding function for fry farming; the steps of the method are as follows: S1: Prepare a variety of feeds required according to the type and growth stage of the fry, including powdered feed, pellet feed and micro feed. Each feed should be stored in an independent space separated by a dividing plate in the dividing sleeve to prevent cross contamination; S2: According to the growth stage, type and nutritional requirements of the fry, the proportion of different types of feed is set on the control system of the feeding device, and the feed can be automatically mixed and fed according to the set proportion; S3: Determine the working time and rotation rate of the stirring mechanism during operation, so as to control the single quantitative amount of feed and feeding time; S4: Determine the area and number of push plates to control the proportion of various feeds; S5: Set the daily feeding time and frequency. For fry farming, feed small amounts and multiple times, 3-6 times a day to avoid feed waste and water quality deterioration.

[0021] The beneficial effects of the present invention are as follows: 1. The present invention is designed with a discharging tray and a distributing mechanism, which can ensure that the feed is evenly distributed throughout the entire breeding area, avoiding the concentration of feed in a certain place, so that each fry can obtain sufficient nutrition to promote its healthy growth. Multiple feed ratios: The design of the distributing mechanism allows for the storage and delivery of a variety of feeds, and can flexibly adjust the types and proportions of feed according to the different growth stages and nutritional needs of the fry, ensuring that the fry receive comprehensive nutritional support. Efficient mixing: The stirring mechanism effectively mixes different types of feed through the interaction of the spiral blades and the vortex push plate, ensuring the uniformity of the feed during the feeding process and improving the feeding efficiency. Reduce feed waste: The design of the sealing component can effectively prevent the moisture and deterioration of the feed, extend the shelf life of the feed, and reduce waste due to deterioration in feed quality.

[0022] 2. The present invention is easy to operate: the design of the movable handle allows the user to easily open and close the sealing component, which improves the convenience of operation. At the same time, the automated design of the material distribution and feeding process reduces manual input, saves time and labor. Improve breeding efficiency: Through precise feed delivery and high-quality feed preservation, the device can increase the growth rate and survival rate of fry, ultimately increasing breeding efficiency and achieving higher economic returns. Health management: The scientific design of the equipment helps to maintain good water quality and feed environment, thereby reducing the risk of disease and providing a healthier growth environment for fry. On the whole, this feeding device improves the overall effect of fry farming and promotes the sustainable development of the aquaculture industry by optimizing feed management and feeding efficiency.

DETAILED DESCRIPTION

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1-8 As shown, a feeding device with a feeding function for fry farming mainly includes key components such as a discharging tray 1, a feeding mechanism 2, a stirring mechanism 3 and a sealing assembly 4. These components cooperate with each other to ensure that the fry can get uniform, quantitative and proportional feed during the farming process, helping the fry to grow and develop better.

[0028] The discharging tray 1 is arranged at the top of the fry breeding device, and its main function is to feed different types of feed to the fry pond below in a uniform distribution. By accurately controlling the landing point and distribution of the feed, the discharging tray 1 can effectively prevent the feed from piling up in one place, ensuring that each fry can get the right amount of feed. This uniform feeding method not only helps to improve the survival rate of the fry, but also reduces feed waste.

[0029] The distributing mechanism 2 is installed above the discharging tray 1 and is responsible for storing different types of feed. Fry have different nutritional requirements at different growth stages and usually require a reasonable combination of multiple feeds. Therefore, the distributing mechanism 2 is designed with multiple storage bins, which can store different types of feeds, such as powdered feed, granular feed, etc. The distributing mechanism 2 can mix different types of feeds as needed according to the set ratio through the internal precise control system. This function ensures that the fry can obtain appropriate nutrition at each growth stage and avoid the problem of uneven growth caused by improper feed ratio.

[0030] The stirring mechanism 3 is located in the middle of the feeding mechanism 2 and plays the role of fully mixing different feeds. The stirring mechanism 3 controls the falling speed of each feed so that different feeds can fall in proportion within an appropriate time and mix in the discharge tray 1, and then be put into the fry pond. The precise control of the stirring mechanism 3 can avoid the phenomenon of uneven mixing of feeds, thereby ensuring that the fry can evenly absorb various nutrients.

[0031] The sealing component 4 is installed above the feed dispensing mechanism 2, and its function is to seal and preserve the stored feed. Since the feed is easily exposed to the air for a long time and is prone to moisture absorption, mold or oxidation deterioration, the sealing component 4 can effectively prevent these problems from occurring, ensuring that the feed remains fresh and dry during use. The design of the sealing component 4 not only prolongs the storage time of the feed, but also reduces the risk of feed waste and feeding failure.

[0032] The discharging tray 1 is composed of a discharging bottom plate 11 and a discharging hole 12. The discharging bottom plate 11 is located below the discharging tray 1 and is designed to be a larger circular structure so as to fit the common circular large tanks in most fry farms. This design can better cover the entire feeding area and ensure that the feed is evenly delivered. There are multiple discharging holes 12 evenly distributed on the discharging bottom plate 11. The arrangement of these holes allows the feed to be distributed to every corner of the fry pond at a stable speed and amount, thereby avoiding the feed from being concentrated in one place. Through this uniform feeding method, it can be effectively ensured that each fry can obtain sufficient nutrition to promote its healthy growth.

[0033] like Figure 4 As shown, the material dividing mechanism 2 includes a material dividing sleeve 21, a fixing column 22, a material dividing partition 23, a mounting magnetic block 24, a material dropping port 25 and a material dividing assembly 26; The dividing sleeve 21 is arranged on the top of the discharge tray 1, the fixed column 22 is installed in the middle of the dividing sleeve 21, the dividing partition plate 23 is installed in the middle of the fixed column 22 and the dividing sleeve 21, the mounting magnetic block 24 is arranged on the top of the fixed column 22, the blanking port 25 is opened on the bottom plate of the dividing sleeve 21, and the dividing assembly 26 is installed in the blanking port 25.

[0034] The number of the dividing baffles 23 is usually set to 2-5, and the specific number depends on the type of feed required during the fry breeding process. An independent cavity will be formed between each dividing baffle 23 and the dividing sleeve 21, which is used to accommodate different types of feed respectively. These independent cavity designs can effectively prevent the mixing of multiple feeds during storage, and maintain their respective quality and freshness. Different types of feed have different preservation requirements, such as moisture-proof and oxidation-proof, so separate storage can reduce the risk of feed deterioration. Through this isolation design, the fry can obtain appropriate nutrition according to the growth stage, ensure that the feeding of the feed is more scientific and accurate, and promote the healthy growth of the fry.

[0035] The material dividing plates 23 are arranged in a circular array around the fixed column 22. This arrangement ensures that each feed compartment is evenly distributed in the material dividing mechanism 2, which is convenient for the independent storage and precise delivery of different types of feed. Each feed drop port 25 is opened in the middle of two adjacent material dividing plates 23. This design can ensure that the feed can smoothly fall from each independent compartment into the discharge tray 1, thereby achieving uniform distribution and mixed feeding of the feed. This structural layout not only optimizes the fluidity of the feed, but also improves the working efficiency of the feeding device, ensuring that the fry are supplied with a variety of feeds in a reasonable proportion.

[0036] like Figure 5 As shown, the material distribution assembly 26 includes a fixed shaft 261 and a push plate 262; the fixed shaft 261 is installed in the blanking port 25, and the intersection of the axis extension lines of multiple fixed shafts 261 coincides with the center point of the fixed column 22; the push plate 262 is installed in the middle of the fixed shaft 261, and four push plates 262 are provided, and the push plates 262 are arranged at equal angles around the fixed shaft 261. The axis extension lines of multiple fixed shafts 261 coincide with the center point of the fixed column 22, which means that the movement of each push plate 262 is symmetrical around the center, which helps to ensure that different feeds enter the discharge tray 1 evenly from each blanking port 25, and avoid the feed from being biased in a certain direction. The push plates 262 are arranged at equal angles around the fixed shaft 261, and the four push plates 262 can evenly push the feed in their respective compartments, so that the feed can flow out from different compartments at the same time, thereby realizing efficient mixing of multiple feeds. The push plate 262 can accurately control the feeding speed and quantity of each feed through the rotation of the fixed shaft 261, ensuring the controllability of the feeding amount, thereby avoiding feed waste and improving feeding efficiency.

[0037] like Figure 6 As shown, the stirring mechanism 3 is composed of a rotating shaft 31, a push rod 32, a spiral blade 33 and a vortex push plate 34, and the various components work in coordination to ensure that the feed is fully mixed and evenly distributed. The rotating shaft 31 is arranged in the middle of the feeding mechanism 2, and is the core supporting part of the entire stirring mechanism 3, and drives other components to work through its rotation. The push rod 32 is located at the upper end of the rotating shaft 31, and is used to push the feed to fall during the feeding process. The spiral blade 33 is installed on the main part of the rotating shaft 31, and the spiral design of the blade helps to generate a rotational driving force during stirring, so that different types of feed are fully stirred and mixed. The vortex push plate 34 is located at the lower end of the rotating shaft 31, and the vortex effect is used to further enhance the stirring effect of the feed, ensuring that the feed has been evenly mixed before falling into the discharge tray 1.

[0038] The push plates are designed to be three and distributed in the stirring mechanism 3 to provide a stable thrust. The two vortex push plates 34 are arranged in a relatively opposite manner. Such a design can effectively push the mixed feed falling in the middle to the surroundings evenly during the rotation process. Due to the special structure of the vortex push plates 34, the feed can be evenly diffused at a slower speed to avoid too fast or uneven delivery, thereby ensuring that the fry in the entire breeding area can obtain an appropriate amount of feed and promote their balanced feeding.

[0039] like Figure 7 As shown, the sealing assembly 4 is composed of a sealing plate 41, a cover plate 42, an inner arc surface 43 and a movable handle 44, etc., which is intended to effectively protect the internal feed and prevent it from being affected by the external environment. The sealing plate 41 is located at the lower part of the sealing assembly 4, and plays the role of basic support and sealing to ensure that the feed is not easy to leak. The cover plate 42 is installed above the sealing plate 41, and closely cooperates with the sealing plate 41 to form a closed space, further enhancing the sealing effect. The inner arc surface 43 is arranged on the inner side of the sealing plate 41 and the cover plate 42, and adopts an arc design, which can better fit the cover plate 42 and enhance the sealing performance. The inner arc surface 43 is also coated with a magnetic coating to ensure that the cover plate 42 can be firmly adsorbed on the sealing plate 41 when closed, avoiding air entry and water evaporation, thereby maintaining the freshness of the feed. The movable handle 44 is installed on the surface of the cover plate 42, which is convenient for users to easily open and close the sealing assembly 4, and the operation is simple and convenient. Through this design, the sealing assembly 4 not only improves the preservation effect of the feed, but also reduces the waste of feed caused by improper storage, providing a more reliable guarantee for fry farming.

[0040] like Figure 8 As shown, a feeding method with a feeding function for fry farming is adapted to the above-mentioned feeding device with a feeding function for fry farming; the steps of the method are as follows: S1: Prepare a variety of feeds required according to the type and growth stage of the fry, including powdered feed, granular feed and micro-feed. Various feeds should be stored in separate spaces separated by the dividing partition 23 in the dividing sleeve 21 to prevent cross contamination; S2: According to the growth stage, type and nutritional requirements of the fry, the proportion of different types of feed is set on the control system of the feeding device, and the feed can be automatically mixed and fed according to the set proportion; S3: Determine the working time and the rotation rate of the stirring mechanism 3 during operation, so as to control the single quantitative amount of feed and the feeding time; S4: Determine the area and number of the pusher plates 262 to control the proportion of various feeds; S5: Set the daily feeding time and frequency. For fry farming, feed small amounts and multiple times, 3-6 times a day to avoid feed waste and water quality deterioration.

[0041] In the working process of the present invention, the staff prepares a variety of feeds required according to the type and growth stage of the fry, including powdered feed, granular feed and micro-feed. Various feeds should be stored in independent spaces separated by the dividing partition 23 in the dividing sleeve 21 to prevent cross contamination. According to the growth stage, type and nutritional requirements of the fry, a driving motor is provided at one end of the upper and lower ends of the rotating shaft 31 in the stirring mechanism 3. The driving motor can set the working time interval and rotation speed through the control system. The feeding ratio of different types of feed can be set on the control system of the feeding device. The feed can be automatically mixed and fed according to the set ratio. The working time and the rotation speed of the stirring mechanism 3 during working are determined to control the single quantitative amount of feed and the feeding time. Determine the area and number of the pusher plates 262 to control the proportion of various feeds; set the daily feeding time and frequency, feed fry in small amounts and multiple meals, and feed fry 3-6 times a day to avoid feed waste and water quality deterioration; During the use of the feeding device, the staff holds the movable handle 44 to open and close the sealing assembly 4, puts feed into the feeding mechanism 2, and then closes it. The magnetic coating of the inner arc surface 43 and the mounting magnetic block 24 attract each other to ensure stability. The sealing plate 41 is stuck in the feeding mechanism 2, and cooperates with the cover plate 42 to ensure the sealing of the feeding mechanism 2. The stirring assembly rotates under the drive of an external driving motor, and the push rod 32 arranged on the top thereof pushes the material return plate to rotate, so as to achieve equal proportion of different feeds. Various feeds fall into the mixing sleeve in a certain proportion, and enter the cavity in the discharge tray 1 under the drive of the spiral blades 33; The vortex push plate 34 rotates continuously to drive the mixed feed in the middle to be pushed evenly and slowly around, so that the feed can flow out of the discharge hole 12 evenly to feed the fry.
