Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and specifically relates to an aquaculture seedling breeding device. Background Art

[0002] Aquaculture is mainly engaged in the breeding of aquatic economic animals and plants, and is one of the agricultural production departments. It is divided into marine aquaculture and freshwater aquaculture according to different water areas. During the large-scale fish breeding process, fry need to be bred separately. The existing methods are mostly to set up separate breeding ponds, and the fry of the same batch can be put into them to breed the aquaculture seedlings of this batch.

[0003] Currently, when feeding the fry in the breeding pond, when the water quality in the pond is poor or the oxygen content in the water decreases, resulting in low activity of the fry. In order to avoid the poor growth of the fry due to the lack of enthusiasm for eating caused by the low activity of the fry in the fry pond, the common method is to turn on the aerator in the pond in advance to improve the activity of the fry. However, this method will cause a large number of fry to gather near the aerator. Therefore, when feeding the feed, the large number of gathered fry compete for the feed more fiercely, and it is easy to cause some fry to not be able to grab the feed. Over time, the growth of the fry in the same batch will show differences, and the sizes of the fry will be different, resulting in poor overall quality of the fry. Summary of the Invention

[0004] The purpose of the present invention is to provide an aquaculture seedling breeding device to replace the traditional fry breeding device, avoiding the problem that when feeding the fry, the insufficient activity of the fry leads to lack of enthusiasm for eating, resulting in different growth of the fry and affecting the overall quality.

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The present invention provides an aquaculture seedling breeding device to replace the traditional fry breeding device, avoiding the problem that when feeding fry with feed, the insufficient activity of the fry leads to inactive eating, resulting in different growth trends of the fry and affecting the overall quality.

[0038] Figures 1 - 10 Shown is a schematic structural diagram of an aquaculture seedling breeding device of the present invention. Please refer to Figures 1 - 10 for a detailed introduction to this aquaculture seedling breeding device.

[0039] Example 1: Refer to Figures 1 - 8 , the present invention discloses an aquaculture seedling breeding device, the main part of which includes a box body 100, a feeding mechanism 200, a vibration mechanism 300 and a water circulation filtering mechanism 400.

[0040] Refer to Figures 1 - 3 , the box body 100 is used to facilitate the carrying and breeding of fry;

[0041] Refer to Figures 1 - 4, the feeding mechanism 200 is used to intermittently throw feed into the box body 100 during working hours. The feeding mechanism 200 is installed on one side of the box body 100 and intermittently throws feed into the box body 100 during working hours, so as to batch throw the feed into the interior of the box body 100 when the feeding mechanism 200 is working, thus avoiding waste of feed caused by some feed not being eaten in time when the feed is concentratedly fed, and affecting the water quality in the box body 100;

[0042] Reference Figures 1 - 7 , the vibration mechanism 300 is used to oscillate and disturb the breeding water inside the box body 100 during working hours. The vibration mechanism 300 is installed inside the box body 100. Among them, when the feeding mechanism 200 is working, the vibration mechanism 300 is automatically driven to start working to oscillate and disturb the water in the box body 100. Then, during the working process of the vibration mechanism 300, the breeding water in the box body 100 is oscillated and disturbed. On the one hand, it improves the activity of the fry, making the fry eat more actively. On the other hand, it simulates the tidal movement, thereby enhancing the ability of the fry to adapt to the external environment in the later stage, and then improving the survival rate of later breeding;

[0043] Reference Figures 1 - 8 , the water circulation and filtration mechanism 400 is used to filter impurities in the box body 100 and make the breeding water in the box body 100 form a water circulation. The water circulation and filtration mechanism 400 is installed inside the box body 100. Among them, when the vibration mechanism 300 is working, the water circulation and filtration mechanism 400 is automatically driven to work. After filtering the impurities in the box body 100, the filtered water is re-introduced into the box body 100. Then, when the vibration mechanism 300 is working, it drives the water circulation and filtration mechanism 400 to start working. During the process of filtering impurities such as feces and residual food in the box body 100, the filtered water is re-introduced into the interior of the box body 100, thereby improving the water quality inside the box body 100. At the same time, after the breeding water forms a cycle, it is more conducive to increasing the oxygen content in the water.

[0044] In this embodiment, the specific use process is as follows: When it is necessary to feed the fry inside the box body 100, the feeding mechanism 200 starts to work, and the feed is intermittently put into the interior of the box body 100 in batches. At the same time, the vibration mechanism 300 starts to work to oscillate and disturb the breeding water in the box body 100, thereby improving the activity of the fry and making the fry eat more actively. During this process, the oscillating breeding water simulates the tidal movement, thereby improving the ability of the fry to adapt to the external environment in the later stage. When the vibration mechanism 300 is working, it drives the water circulation and filtration mechanism 400 to start working, filters impurities such as fry feces and residual food in the box body 100, improves the water quality, and at the same time re-introduces the filtered water back into the box body 100 to form a water circulation, thereby increasing the oxygen content after increasing the exposure of the breeding water, making the fry eat more actively and not easily gather.

[0045] Example 2: On the basis of Example 1, referring to Figures 1 - 6 , the feeding mechanism 200 includes a receiving groove 210 installed on the side wall of the box body 100 and having an opening on one side, a feeding trough 220 located on one side of the receiving groove 210, a feeding guide groove 230 with one end communicating with the feeding trough 220 and the other end communicating with the receiving groove 210, and a driving assembly 240 that intermittently introduces the feed in the feeding trough 220 into the receiving groove 210 during operation and throws the feed introduced into the receiving groove 210. The receiving groove 210 is used for temporarily storing the feed, the feeding trough 220 is used for storing the feed to be delivered, the feeding guide groove 230 is used for introducing the feed in the feeding trough 220 into the receiving groove 210, and the driving assembly 240 is used for introducing the feed in the feeding trough 220 into the receiving groove 210 in batches during operation and throwing the feed introduced into the receiving groove 210 into the box body 100.

[0046] In this embodiment, referring to Figures 4 - 6 , a feeding guide cover 211 with an arc-shaped structure is provided at the opening of the receiving groove 210, which is used to facilitate the formation of a parabola of the feed when the scraping plate 2421 rotates here, so that the feed is more dispersed after being thrown.

[0047] Referring to Figures 4 - 6 , the driving assembly 240 includes a driving motor 241 located on one side of the receiving groove 210, a first connecting shaft 242 located in the receiving groove 210 and having a scraping plate 2421 on its side wall, and a second connecting shaft 243 located in the feeding guide groove 230 and having four baffles 2431 on its side wall. One end of the first connecting shaft 242 has a first cam 2422, and one end of the second connecting shaft 243 has four second cams 2432. The driving motor 241 is used to drive the first connecting shaft 242 to rotate during operation. The first connecting shaft 242 is used to drive the scraping plate 2421 to rotate when rotating. The scraping plate 2421 is used to intermittently scrape away the feed in the receiving groove 210 and throw it out from the feeding guide cover 211 during the rotation process. The second connecting shaft 243 is used to drive the four baffles 2431 to deflect when rotating. The four baffles 2431 are used to form a trough for accommodating the feed among them. Thus, every time the second connecting shaft 243 rotates once, the feed in the trough between two baffles 2431 is driven into the receiving groove 210, and the adjacent troughs are filled with feed again. Among them, the gap between two adjacent second cams 2432 is adapted to the first cam 2422, which is used to drive the second connecting shaft 243 to rotate one-fourth of a circle when the first connecting shaft 242 rotates one circle, so as to facilitate the intermittent introduction of the feed in the feeding trough 220 into the receiving groove 210 in batches.

[0048] In this embodiment, the specific working process is as follows: when it is necessary to feed, first pour the feed into the feeding trough 220, and the driving motor 241 starts to work to drive the first connecting shaft 242 to rotate. When the first connecting shaft 242 rotates, the cooperation of the first cam 2422 and the second cam 2432 drives the second connecting shaft 243 to rotate intermittently, so that the feed in the feeding trough 220 is intermittently transferred to the containing trough 210 through the trough body between the two adjacent baffles 2431, so that when the scraper 2421 rotates, the newly introduced feed runs into the box 100 through the material guide cover 211, thereby completing the intermittent feeding of the inside of the box 100 in batches.

[0049] Example 3: Based on Example 2, Figures 1 - 7 The vibration mechanism 300 includes a fixed plate 310 installed at both ends of the inner wall of the box body 100, a plurality of first elastic members 320 located at the bottom of the fixed plate 310, a vibration frame 330 whose side wall is slidably connected to the inner wall of the box body 100 and whose top is connected to the bottom of the first elastic member 320, and a transmission assembly 340 whose one end is transmission-connected to the vibration frame 330 and the other end is transmission-connected to the driving assembly 240. The fixed plate 310 is used to facilitate the installation of the first elastic member 320. The first elastic member 320 is used to provide a rebound force when compressed, so that the vibration frame 330 vibrates back and forth repeatedly. The vibration frame 330 is used to vibrate the aquaculture water in the box body 100 when it vibrates up and down reciprocatingly. The transmission assembly 340 is used to drive the vibration frame 330 to vibrate up and down when the driving assembly 240 is working.

[0050] In this embodiment, reference Figure 4 The first connecting shaft 242 has a first belt pulley 2423 at one end adjacent to the first cam 2422, which is used to drive the second belt pulley 343 to rotate when rotating;

[0051] refer to Figures 1 - 7 The transmission assembly 340 includes a third connecting shaft 341 movably mounted on the inner wall of the box body 100, third cams 342 located at both ends of the third connecting shaft 341 and corresponding to the bottom of the vibration frame 330, and a second pulley 343 located at one end of the third connecting shaft 341 and connected to each other by a belt, wherein one of the second pulleys 343 is connected to the first pulley 2423 by a belt, and the third connecting shaft 341 is used to drive the third cams 342 at both ends to rotate when rotating, and the third cam 342 is used to drive the vibration frame 330 to reciprocate up and down vibration along the inner wall of the box body 100 when rotating, and the second pulley 343 is used to drive the two third connecting shafts 341 to rotate when rotating.

[0052] In this embodiment, the specific working process is as follows: when the first connecting shaft 242 rotates to feed, the first pulley 2423 rotates to drive the second pulley 343 to rotate, and when the second pulley 343 rotates, it drives the two third connecting shafts 341 to rotate, and when the third connecting shaft 341 rotates, it drives the third cams 342 at both ends to start rotating, and when the third cam 342 rotates, it intermittently squeezes the bottom of the vibration frame 330, thereby driving the vibration frame 330 to vibrate up and down reciprocatingly. When the vibration frame 330 vibrates up and down reciprocatingly, the breeding water in the box 100 is vibrated and disturbed, thereby improving the activity of the fry, making the fry more motivated to eat, and at the same time simulating tidal movement to increase the adaptability of the fry to the later environment.

[0053] Example 4: Based on Example 3, Figures 1 - 8 The water circulation filtering mechanism 400 includes a hydrophobic slag guiding component 410 installed in the housing 100 and transmission-connected to the vibration frame 330, a venturi tube 420 whose input end is connected to the output end of the hydrophobic slag guiding component 410 and whose bottom of the diffusion section of the output end is connected to a collecting box 421, and a pressurized water circulation component 430 whose input end is connected to the output end of the venturi tube 420. The hydrophobic slag guiding component 410 is used to guide the turbid water in the housing 100 during operation, and to guide the impurities such as fish feces and leftover food in the water. The venturi tube 420 is used to separate the impurity particles in the turbid water transmitted by the hydrophobic slag guiding component 410 from the water, so that the impurity particles in the water are collected after being precipitated through the collecting box 421. The pressurized water circulation component 430 is used to pressurize the water separated from the impurity particles in the venturi tube 420 and re-introduce it into the housing 100.

[0054] In this embodiment, reference Figure 7 The bottom side of the vibration frame 330 has a sawtooth plate 331, which is used to drive the ratchet 413 to rotate during the process of the vibration frame 330 moving up and down to drive the sawtooth plate 331 to move up and down;

[0055] refer to Figure 8 The drain and slag guiding assembly 410 includes a filter cover 411 installed in the box body 100, a reducer auger 412 located in the filter cover 411, and a ratchet 413 connected to one end of the reducer auger 412 through a rotating shaft and corresponding to the serrated plate 331. The filter cover 411 is used to guide the turbid water in the box body 100, and after filtering and limiting the impurity particles inside, it is prevented that the impurity particles are re-diffused into the box body 100 during the transmission process. The reducer auger 412 is used to gradually transfer the turbid water entering the filter cover 411 to the inside of the venturi tube 420 when rotating. At the same time, the reducer structure gradually conducts, crushes and squeezes the impurity particles and then introduces them into the venturi tube 420, thereby improving the efficiency of purifying the impurity particles. The ratchet 413 is used to drive the reducer auger 412 to rotate when rotating.

[0056] In this embodiment, referring to Figures 3 - 9 , the pressurized water circulation assembly 430 includes a return pipe 431 with one end flange-connected to the output end of the Venturi tube 420 and the other end extending above the box body 100, and a first impeller 432 located in the return pipe 431 and connected to the other end of the variable-diameter auger 412 through a rotating shaft. The return pipe 431 is used to redirect the aquaculture water output from the output end of the Venturi tube 420 back into the box body 100. The first impeller 432 is used to pressurize the aquaculture water entering the return pipe 431 when rotating, so as to increase the flow velocity of the water flow, facilitating the smooth return of the aquaculture water in the return pipe 431 to the inside of the box body 100. At the same time, the rotation of the first impeller 432 increases the exposure of the aquaculture water, thereby enhancing the oxygen content of the aquaculture water. Meanwhile, after the aquaculture water circulates, it can effectively cool the aquaculture water, so that when the water temperature in the box body 100 rises, it automatically plays a role in cooling the aquaculture water.

[0057] In this embodiment, the specific working process is as follows: When the vibration frame 330 moves up and down to drive the sawtooth plate 331 to move, the driving ratchet 413 rotates. When the ratchet 413 rotates, it drives the variable-diameter auger 412 to rotate. When the variable-diameter auger 412 rotates, it conducts the impurity particles and water of the turbid water entering the filter cover body 411 into the Venturi tube 420. The Venturi tube 420 settles the dirt particles in the water at the diffuser section of the output end through its own characteristics and then guides them into the collection box 421. The aquaculture water enters the return pipe 431. At this time, the rotation of the variable-diameter auger 412 drives the first impeller 432 to rotate, thereby pressurizing the aquaculture water entering the return pipe 431 and then redirecting it into the box body 100, thus forming a water cycle.

[0058] Embodiment 5: On the basis of Embodiment 4, in order to prevent the water temperature in the box body 100 from being too high, which may affect the health of the fry, referring to Figures 1 - 10 , it further includes an adjustment mechanism 500, which is used to automatically increase the water circulation speed when the water temperature in the box body 100 is too high, thereby improving the efficiency of cooling the water in the box body 100. Referring to Figures 8 - 9, the adjusting mechanism 500 includes a branch pipe 510 located on one side of the return pipe 431, with one end communicating with the input end of the return pipe 431 and the other end communicating with the output end of the return pipe 431, a second impeller 520 located at the input end of the branch pipe 510, and a trigger assembly 530 that triggers the rotation of the second impeller 520 when the water temperature in the box body 100 is too high. The branch pipe 510 is used to guide the excess aquaculture water entering the return pipe 431. The second impeller 520 is used to pressurize the aquaculture water entering the branch pipe 510 during rotation and then introduce it to the outlet of the return pipe 431, thereby increasing the circulation rate of the aquaculture water. The trigger assembly 530 is used to increase the water inflow of the return pipe 431 and drive the second impeller 520 to rotate when the water temperature entering the return pipe 431 increases.

[0059] In this embodiment, referring to Figures 8 - 10 , the inner wall bottom of the input end of the return pipe 431 has a limit sliding groove for slidably connecting a moving block 5321. The connecting rotating shaft of the first impeller 432 has a first gear 4321 for cooperating with a bevel gear set 5322, so as to drive the bevel gear set 5322 to rotate when meshing with the bevel gear set 5322. The side wall of the second impeller 520 is connected with a second gear 521 through a connecting shaft for driving the second impeller 520 to rotate during rotation;

[0060] Referring to Figures 8 - 10 , the trigger assembly 530 includes a bimetallic speed regulating valve 531 installed at the pipe orifice of the return pipe 431 and a trigger member 532 located in the limit sliding groove. The bimetallic speed regulating valve 531 is composed of a copper-steel composite sheet, and the valve sheet rotates eight degrees for every one-degree increase in water temperature, so that the amount of water entering the return pipe 431 increases accordingly. The trigger member 532 includes a moving block 5321 with the bottom extending into the limit sliding groove and a second elastic member 53211 on one side, a bevel gear set 5322 located on the other side of the moving block 5321, and a third gear 5323 connected to the other end of the bevel gear set 5322. The other end of the second elastic member 53211 is connected to the inner wall of the limit sliding groove. The moving block 5321 is used to facilitate the installation of the bevel gear set 5322 and bear the pressure of the water flowing through the return pipe 431. The bevel gear set 5322 is used to indirectly drive the third gear 5323 to rotate when the water flow increases and the moving block 5321 moves to a position meshing with the first gear 4321. The third gear 5323 is used to drive the second gear 521 to rotate during rotation, and the second elastic member 53211 is used to limit the moving block 5321 through its own elastic force.

[0061] In this embodiment, the specific working process is as follows: when the water temperature in the return pipe 431 increases, the bimetal speed control valve 531 automatically opens to increase the flow rate. When the water temperature reaches a certain value, the water flow entering the return pipe 431 becomes larger and impacts the moving block 5321. The moving block 5321 moves along the limit chute until the bevel gear set 5322 meshes with the first gear 4321. At this time, the rotation of the first gear 4321 drives the rotation of the bevel gear set 5322. The rotation of the bevel gear set 5322 drives the rotation of the third gear 5323. When the third gear 5323 rotates, it drives the second impeller 520 to rotate, so as to increase the water volume and pressurize and transport the aquaculture water entering the branch pipe 510 to the outlet of the return pipe 431, thereby accelerating the water outlet speed of the return pipe 431, improving the water circulation rate, and further enhancing the efficiency of cooling the aquaculture water inside the box body 100.
