Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to an aquatic seedling propagation device. Background Art

[0002] Aquaculture is mainly engaged in the breeding of aquatic economic animals and plants. It is one of the agricultural production sectors and is divided into marine aquaculture and freshwater aquaculture according to the nature of the water area. In the process of large-scale fish farming, the fry need to be bred separately. The existing means are mostly to set up separate breeding ponds, and the same batch of aquatic seedlings can be placed in them to breed the batch.

[0003] At present, when feeding the fry in the breeding pond, when the water quality in the pond is poor or the oxygen content in the water is reduced, the activity of the fry is not high. In order to avoid the low activity of the fry in the fry pond, which leads to insufficient enthusiasm for eating and poor growth, a common method is to turn on the aerator in the pond in advance to increase the activity of the fry. However, this method will cause a large number of fry to gather near the aerator. When feeding, the large number of gathered fry will compete fiercely for the feed, which may easily cause some fry to not be able to grab the feed. As a result, over time, there will be differences in the growth of the same batch of fry, and the fry will be of different sizes, resulting in poor overall quality of the fry.

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] The invention provides an aquatic seedling breeding device, which replaces the traditional fish seedling breeding device and avoids the problem that when the fish seedlings are fed with feed, the fish seedlings are not active enough and thus eat inactively, thus causing different growth of the fish seedlings and affecting the overall quality.

[0020] Figure 1-Figure 10 The structure diagram of the aquatic seedling propagation device of the present invention is shown in FIG. Figure 1-Figure 10 A detailed introduction is given to this type of aquatic seed propagation device.

[0021] Example 1: Reference Figure 1-Figure 8 The present invention discloses an aquatic seedling propagation device, the main body of which includes a box body 100, a feeding mechanism 200, a vibration mechanism 300 and a water circulation filtering mechanism 400.

[0022] refer to Figure 1-Figure 3 The box 100 is used to facilitate the carrying and breeding of fry; refer to Figure 1-Figure 4 The feeding mechanism 200 is used to throw feed into the box 100 intermittently during operation. The feeding mechanism 200 is installed on one side of the box 100 and throws feed into the box 100 intermittently during operation, so that the feed is thrown into the box 100 in batches when the feeding mechanism 200 is working, thereby avoiding the waste of feed caused by part of the feed not being eaten in time when the feed is fed in batches, and affecting the water quality in the box 100; refer to Figure 1-Figure 7 The vibration mechanism 300 is used to oscillate and disturb the aquaculture water inside the box 100 when working. The vibration mechanism 300 is installed in the box 100. 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 100. In the process of the vibration mechanism 300 working, the aquaculture water in the box 100 is oscillated and disturbed. On the one hand, the activity of the fry is improved, making the fry eat more actively. On the other hand, the tidal movement is simulated, thereby enhancing the ability of the fry to adapt to the external environment in the later stage, thereby improving the survival rate of the later aquaculture; refer to Figure 1-Figure 8The water circulation filtering mechanism 400 is used to filter out impurities in the box 100 and make the aquaculture water in the box 100 form a water circulation. The water circulation filtering mechanism 400 is installed in the box 100. When the vibration mechanism 300 is working, the water circulation filtering mechanism 400 is automatically driven to work. After filtering out impurities in the box 100, the filtered water is reintroduced into the box 100. Then, when the vibration mechanism 300 is working, the water circulation filtering mechanism 400 is driven to start working. In the process of filtering out impurities such as feces and leftovers in the box 100, the filtered water is reintroduced into the box 100, thereby improving the water quality inside the box 100. At the same time, after the aquaculture water forms a circulation, it is more conducive to increasing the oxygen content in the water.

[0023] In this embodiment, the specific use process is as follows: when it is necessary to feed the fry inside the box 100, the feeding mechanism 200 starts working, and the feed is intermittently put into the box 100 in batches. At the same time, the vibration mechanism 300 starts working to oscillate and disturb the aquaculture water in the box 100, thereby increasing the activity of the fry and making the fry eat more actively. In this process, the aquaculture water under vibration simulates 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 filtering mechanism 400 to start working, and filter out impurities such as fry feces and leftover food in the box 100 to improve the water quality. At the same time, the filtered water is re-directed back into the box 100 to form a water cycle, thereby increasing the exposure of the aquaculture water and increasing the oxygen content, making the fry eat more actively and not easy to aggregate.

[0024] Example 2: Based on Example 1, Figure 1-Figure 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 groove 220 located on one side of the receiving groove 210, a food guide groove 230 connected to the feeding groove 220 at one end and connected to the receiving groove 210 at the other end, and a driving component 240 for intermittently introducing the feed in the feeding groove 220 into the receiving groove 210 and throwing out the feed introduced into the receiving groove 210 during operation. The receiving groove 210 is used for temporarily storing the feed, the feeding groove 220 is used for storing the feed to be put in, the food guide groove 230 is used for introducing the feed in the feeding groove 220 into the receiving groove 210, and the driving component 240 is used for introducing the feed in the feeding groove 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.

[0025] In this embodiment, reference Figure 4-Figure 6 The opening of the receiving groove 210 has an arc-shaped guide cover 211, which is used to facilitate the scraper 2421 to rotate to this point, so that the feed forms a parabola and is thrown out, thereby making the feed more dispersed after being thrown out; refer to Figure 4-Figure 6 The driving assembly 240 includes a driving motor 241 located at one side of the receiving groove 210, a first connecting shaft 242 located in the receiving groove 210 and having a scraper 2421 on the side wall, and a second connecting shaft 243 located in the food guiding groove 230 and having four baffles 2431 on the 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, and the first connecting shaft 242 is used to drive the scraper 2421 to rotate during rotation. The scraper 2421 is used to intermittently scrape the feed in the receiving groove 210 during the rotation process. After walking, it is thrown out from the material guide cover 211, and 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 body for accommodating feed between each other, so that each time the second connecting shaft 243 rotates once, the feed in the trough body between the two baffles 2431 is driven to enter the containing trough 210, and the adjacent trough bodies are filled with feed again, wherein the gap between the two adjacent second cams 2432 is adapted to the first cam 2422, so that the first connecting shaft 242 rotates one circle to drive the second connecting shaft 243 to rotate a quarter circle, thereby facilitating the intermittent introduction of the feed in the feeding trough 220 into the containing trough 210 in batches.

[0026] 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.

[0027] Example 3: Based on Example 2, Figure 1-Figure 7The 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.

[0028] 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; refer to Figure 1-Figure 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.

[0029] 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.

[0030] Example 4: Based on Example 3, Figure 1-Figure 8The 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.

[0031] 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; 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.

[0032] In this embodiment, reference Figure 3-Figure 9The pressurized water circulation component 430 includes a return pipe 431, one end of which is connected to the output end of the venturi tube 420 through a flange and the other end of which extends to the top of the box 100, and a first impeller 432 located in the return pipe 431 and connected to the other end of the reducer auger 412 through a rotating shaft. The return pipe 431 is used to redirect the aquaculture water output through the output end of the venturi tube 420 back into the box 100. The first impeller 432 is used to pressurize the aquaculture water entering the return pipe 431 when rotating, thereby increasing the flow rate of the water flow, so that the aquaculture water in the return pipe 431 can smoothly return to the inside of the box 100. At the same time, the first impeller 432 rotates to increase the exposure of the aquaculture water, thereby enhancing the oxygen content of the aquaculture water. At the same time, the aquaculture water can be effectively cooled after circulating, so that after the temperature of the aquaculture water in the box 100 increases, it automatically cools the aquaculture water.

[0033] In this embodiment, the specific working process is as follows: when the vibration frame 330 moves up and down and drives the sawtooth plate 331 to move, the ratchet 413 is driven to rotate, and when the ratchet 413 rotates, it drives the reducing auger 412 to rotate. When the reducing auger 412 rotates, the impurity particles and water of the turbid water entering the filter cover 411 are conducted to the inside of the venturi tube 420. The venturi tube 420 uses its own characteristics to settle the dirt particles in the water in the diffusion section at the output end and then introduces it into the collection box 421, and the aquaculture water enters the return pipe 431. At this time, the reducing auger 412 rotates and drives the first impeller 432 to rotate, thereby pressurizing the aquaculture water entering the return pipe 431 and re-introducing it into the box 100, thereby forming a water cycle.

[0034] Example 5: Based on Example 4, in order to prevent the water temperature in the box 100 from being too high, thereby affecting the health of the fry, refer to Figure 1-Figure 10 , and also includes an adjustment mechanism 500, which is used to automatically increase the water circulation speed when the water temperature in the box 100 is too high, thereby improving the efficiency of cooling the water in the box 100, referring to Figure 8-Figure 9 The regulating mechanism 500 includes a branch pipe 510 located at one side of the return pipe 431 and having one end connected to the input end of the return pipe 431 and the other end connected to 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 component 530 for triggering the second impeller 520 to rotate when the water temperature in the box 100 is too high. The branch pipe 510 is used to guide the excess aquaculture water entering the return pipe 431. When the second impeller 520 is used to rotate, the aquaculture water entering the branch pipe 510 is pressurized and introduced into the outlet of the return pipe 431, thereby increasing the circulation rate of the aquaculture water. The trigger component 530 is used to increase the water inlet of the return pipe 431 when the water temperature entering the return pipe 431 increases, and drive the second impeller 520 to rotate.

[0035] In this embodiment, reference Figure 8-Figure 10 The bottom of the inner wall of the input end of the return pipe 431 has a limiting sliding groove for slidingly connecting the moving block 5321. The connecting shaft of the first impeller 432 has a first gear 4321 for cooperating with the bevel gear set 5322, so that when meshing with the bevel gear set 5322, the bevel gear set 5322 is driven to rotate. The side wall of the second impeller 520 is connected to a second gear 521 through a connecting shaft, which is used to drive the second impeller 520 to rotate when rotating; refer to Figure 8-Figure 10 The trigger assembly 530 includes a bimetallic speed regulating valve 531 installed at the mouth of the return pipe 431 and a trigger member 532 located in the limit slide. The bimetallic speed regulating valve 531 is composed of a copper-steel composite plate. When the water temperature rises by one degree Celsius, the valve plate is driven to rotate eight degrees, thereby increasing the amount of water entering the return pipe 431. The trigger member 532 includes a moving block 5321 with a bottom extending into the limit slide and having a second elastic member 53211 on one side, and a second elastic member 5321 located on the other side of the moving block 5321. The bevel gear set 5322 and the 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 limiting slideway, the moving block 5321 is used to facilitate the installation of the bevel gear set 5322 and to bear the pressure on 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 the position meshing with the first gear 4321. The third gear 5323 is used to drive the second gear 521 to rotate when rotating, and the second elastic member 53211 is used to limit the moving block 5321 by its own elastic force.

[0036] In this embodiment, the specific working process is as follows: when the temperature of the water entering the return pipe 431 increases, the bimetallic speed regulating 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 limiting slide until the bevel gear set 5322 engages with the first gear 4321. At this time, the first gear 4321 rotates to drive the bevel gear set 5322 to rotate, and the bevel gear set 5322 rotates to drive the third gear 5323 to rotate. When the third gear 5323 rotates, it drives the second impeller 520 to rotate, so that the aquaculture water entering the branch pipe 510 with increased water volume is pressurized and transported to the outlet of the return pipe 431, thereby accelerating the water outlet speed of the return pipe 431, thereby increasing the water circulation rate, and further improving the efficiency of cooling the aquaculture water inside the box 100.

[0037] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
