Description

Technical Field

[0001] This invention relates to the field of fish fry farming technology, specifically to a fully automatic feeding device for zebrafish fry. Background Technology

[0002] When raising zebrafish fry, it is often necessary to manually introduce a certain amount of cultured paramecium into the breeding pond at regular intervals to provide food for the zebrafish fry. However, in large-scale breeding, manual feeding is not only inefficient and slow, but also requires separate cultivation of paramecium, which is very inconvenient.

[0003] Even though there are some zebrafish breeding equipment on the market, such as the zebrafish breeding and rearing system with patent publication number CN215346524U, which includes: a support frame including a vertical plate, on which placement plates are fixedly connected, with at least two placement plates; a rearing tank for culturing broodstock, pairing, hatching eggs, rearing newly hatched fry, and rearing juveniles; and a water circulation system for circulating the water in the rearing tank to ensure water quality. The advantages of this invention are that culturing broodstock before pairing ensures their health at the time of pairing, increasing the reproduction rate; the water circulation system circulates the water in the rearing tank; and the use of paramecium culture solution to gradually replace the rearing water during the feeding of newly hatched fry improves their survival rate and reduces the workload of the breeder.

[0004] However, the publicly disclosed feeding system for newly hatched fry and juvenile zebrafish still has the following problems: Directly feeding newly hatched fry with paramecium culture solution increases labor costs. Furthermore, if the feeding is uneven in a single pond, some zebrafish fry may not get enough food, affecting their uniform growth. Also, feeding does not increase oxygen levels in the water, impacting fry growth. The paramecium culture solution is cultivated using yeast powder. When this solution is added to the pond, the yeast powder easily settles to the bottom, causing water deterioration. Moreover, the water circulation system cannot purify and collect the sediment along with the yeast powder; it only purifies the water, easily leading to water deterioration. Secondly, it cannot automatically cultivate zebrafish fry feed (paramecium) using the water, nor can it automatically and evenly feed the cultivated feed to the fry, failing to make rational resource reuse. Therefore, a fully automatic zebrafish fry feeding device is provided. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fully automatic zebrafish fry feeding device to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic feeding device for zebrafish fry, comprising a zebrafish fry rearing pond, a rearing pond water filtration box, a paramecium rearing feed box, a paramecium grading rearing box, and a paramecium rearing tank. The zebrafish fry rearing pond and the rearing pond water filtration box are connected by a pipe equipped with a one-way valve. The rearing pond water filtration box and the paramecium rearing feed box are connected by a connecting pipe A equipped with a one-way valve.

[0008] The bottom of the paramecium rearing tank is connected to a yeast powder filter box, which is connected to a return water pipe in the zebrafish fry rearing pond via a connecting pipe C equipped with a centrifugal pump B.

[0009] As a preferred embodiment of the present invention, the zebrafish fry rearing pond is provided with several rearing tanks inside, and each rearing tank is connected to the other through a through hole.

A yeast powder storage hopper is welded to the outer periphery of the yeast powder conveying pipe, and a yeast powder inlet is provided at the periphery of the yeast powder conveying pipe inside the yeast powder storage hopper.

[0013] As a preferred embodiment of the present invention, the interior of the paramecium grading and breeding box is composed of several paramecium breeding tanks of different depths. The height difference between any two adjacent paramecium breeding tanks is the same, and the paramecium breeding tanks with the same height difference are connected by a connecting pipe equipped with a solenoid valve B.

[0014] As a preferred embodiment of the present invention, the paramecium breeding tank includes a top plate welded to several water supply pipes, a filter inner cylinder fixed inside the paramecium breeding tank, and a filter inner cylinder cleaning device inserted into the filter inner cylinder. A reduction gearbox A is installed at the top center of the top plate, a motor A is installed on the top of the reduction gearbox A, and a rotating shaft is connected to the bottom of the reduction gearbox A. Several stirring rods are evenly welded on the circumference of the rotating shaft, and four filter inner cylinder cleaning devices are also evenly welded on the rotating shaft.

[0018] The water quality sensor is electrically connected to the solenoid valve, motor B, centrifugal pump A, and centrifugal pump B on the water supply pipe and the water outlet pipe respectively via a controller.

[0019] The density sensor is electrically connected to centrifugal pump A and alarm via a controller.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention combines the cultivation of paramecium with the feeding of zebrafish fry. The water used for zebrafish fry rearing is purified and reused in paramecium rearing. After rearing, the paramecium is transported back to the rearing pond along with the water. This achieves water purification and recycling while simultaneously feeding the zebrafish fry with paramecium. It not only realizes automatic feeding of zebrafish fry but also solves the problems of feed for zebrafish fry and water quality in the rearing pond.

[0022] This invention filters the water in the zebrafish fry rearing pond and then transports it along with paramecium mother liquor and yeast powder to the paramecium rearing tank for zebrafish feed (paramecium) rearing. This achieves both zebrafish rearing water purification and automatic feeding of zebrafish feed materials.

[0023] This invention allows for graded breeding of paramecia, with the cultured paramecia being regularly transported to various breeding areas to feed zebrafish, while simultaneously achieving the recycling and purification of the breeding water.

[0024] This invention circulates and purifies the water used for zebrafish farming before using it as culture water for feeding zebrafish fry. After further purification and filtration of yeast powder, the culture water containing paramecium is transported to the zebrafish fry rearing pond. This not only achieves the circulation and purification of the farming water, but also introduces air into the zebrafish fry rearing pond while spraying water to provide oxygen for the zebrafish. At the same time, some paramecium can also be transported into the zebrafish fry rearing pond to feed the zebrafish.

[0025] This invention divides the zebrafish fry rearing pond into multiple rearing areas using feeding pipes, allowing the zebrafish fry to be reared in small units. Feed is then distributed to these smaller units to ensure sufficient food for the fry and improve the quality of feeding. Furthermore, a water quality sensor monitors the water quality in real time, automatically changing the water if the filtered water quality is still insufficient, thus guaranteeing the quality of the water used for zebrafish fry rearing.

[0026] This invention features a bottom tank at the bottom of the zebrafish fry rearing pond, which is connected to the pond itself. This tank collects the yeast powder that settles in the rearing water. By controlling the forward and reverse rotation of motor B, the auger A agitates the settled yeast powder during water changes or purification. This facilitates the discharge of the yeast powder during water changes and allows it to be easily drawn into the water filter box for collection and treatment during water purification, thus preventing the yeast powder from affecting the water quality.

[0027] In the process of feeding zebrafish fry, the present invention activates an electric lifting rod. The up-and-down movement of the electric lifting rod allows the brush on the inner side of the cleaning ring plate of the net cage to clean the mesh holes around the zebrafish fry rearing net cage, preventing the mesh holes from becoming clogged. This facilitates the smooth entry of paramecia into the zebrafish fry rearing net cage, thus improving the quality of automatic feeding.

[0028] This invention uses paramecium culture tanks of different depths to achieve tiered and graded culture of paramecium, ensuring that the paramecium provided to the zebrafish fry rearing ponds are of uniform size, thus making the feed supply to the zebrafish fry more even and sufficient. The graded culture also allows the paramecium sufficient growth time, while avoiding the mixing of paramecium of different sizes, which would cause some smaller paramecium to be fed prematurely as feed, thereby increasing the cost of mother liquor.

[0029] This invention uses high-pressure water to transport paramecium mother liquor and yeast powder into the filter inner cylinder. A high-speed stirring rod ensures the yeast powder is fully dissolved in the water. This process further enhances the dissolution of the yeast powder while it is being transported through the pipeline. Simultaneously, the filter inner cylinder prevents undissolved yeast powder and paramecium from being transported to the zebrafish fry rearing pond. During stirring, a significant amount of yeast powder adheres to the filter pores of the inner cylinder. Therefore, a cleaning device within the filter inner cylinder cleans the pores while stirring, increasing the dissolution rate of the yeast powder and preventing clogging, thus facilitating the passage of paramecium.

[0050] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0051] Example: Please refer to Figure 1-4This invention provides a technical solution: a fully automatic zebrafish fry feeding device, comprising a zebrafish fry rearing pond 1, a rearing pond water filtration box 2, a paramecium rearing feed box 3, a paramecium grading rearing box 4, and a paramecium rearing tank 5. The zebrafish fry rearing pond 1 and the rearing pond water filtration box 2 are connected by a pipe equipped with a one-way valve to filter the rearing water in the zebrafish fry rearing pond 1, thereby purifying the rearing water. The rearing pond water filtration box 2 and the paramecium rearing feed box 3 are connected by a connecting pipe A201 equipped with a one-way valve 202. When the filtered water passes through the paramecium rearing feed box 3, paramecium mother liquor and yeast powder are added to the paramecium rearing feed box 3, allowing the paramecium mother liquor and yeast powder to be transported together with the purified water into the paramecium rearing tank 5, thereby achieving rearing. The automatic feeding of paramecium mother liquor and yeast powder is achieved through a one-way valve 202, which prevents the mother liquor and yeast powder from flowing into the water filter box 2 of the breeding pond. The feeding box 3 for paramecium breeding is connected to the water supply pipe 503 located at the top of the paramecium breeding tank 5 via a connecting pipe B511 equipped with a centrifugal pump A510. The breeding water containing paramecium mother liquor and yeast powder is transported to the paramecium breeding tank 5 for paramecium breeding. Yeast powder is the nutrient for paramecium, so it needs to be added when breeding paramecium. This technical solution filters the breeding water in the zebrafish fry breeding pond 1 and then transports it together with the paramecium mother liquor and yeast powder to the paramecium breeding tank 5 for zebrafish feed (paramecium) breeding. This achieves zebrafish breeding water purification treatment while automatically feeding zebrafish feed raw materials.

[0052] Paramecium rearing tank 5 is connected to paramecium grading rearing box 4 via connecting pipe D406 equipped with solenoid valve C407. Paramecium in paramecium rearing tank 5 is transported to paramecium grading rearing box 4 to achieve graded rearing. The purpose of graded rearing is to ensure that the zebrafish eat food of relatively uniform size each time. Paramecium grading rearing box 4 is connected to paramecium delivery pipe 104 set in zebrafish fry rearing pond 1 via paramecium feeding pipe 401 equipped with solenoid valve A402. Paramecium in paramecium grading rearing box 4 is transported to paramecium delivery pipe 104 and flows out through the outlet of paramecium delivery pipe 104, thus automatically feeding the zebrafish in zebrafish fry rearing net cage 111. This technical solution can grade paramecium and transport the cultivated paramecium to various rearing areas for feeding zebrafish at regular intervals. At the same time, it also realizes the circulation and purification of the rearing water.

[0053] The bottom of the paramecium rearing tank 5 is connected to a yeast powder filter box 505. The yeast powder filter box 505 is connected to the return water pipe 105 in the zebrafish fry rearing pond 1 via a connecting pipe C512 equipped with a centrifugal pump B513. The yeast powder filter box 505 filters out large particles of yeast powder and impurities. Some paramecia and filtered water are transported to the return water pipe 105 through the connecting pipe C512 and discharged through the outlet of the return water pipe 105, thus achieving the purpose of water circulation and oxygen supply. This technical solution is to circulate and purify the zebrafish rearing water before using it as culture water for zebrafish fry feed. After further purification and filtration of yeast powder, the culture water containing paramecia is transported to the zebrafish fry rearing pond 1. This not only achieves the circulation and purification of the rearing water, but also brings air into the zebrafish fry rearing pond 1 to provide oxygen for the zebrafish while spraying water. At the same time, some paramecia can also be transported to the zebrafish fry rearing pond 1 to feed the zebrafish.

[0054] like Figure 5 As shown, the zebrafish fry rearing pond 1 has several rearing tanks 103 inside, and each rearing tank 103 is connected by a through hole 108 to facilitate water circulation during later water replenishment and to allow paramecia to move in different areas. Each rearing tank 103 is divided into four identical spaces for storing zebrafish fry rearing net cages 111 by a paramecium delivery pipe 104, ensuring that each zebrafish fry rearing net cage 111 is separated, which is beneficial for later regional feeding. A water quality sensor 107 is installed on the inner wall of each rearing tank 103, and several outlets are opened on the return water pipe 105. Several outlets are opened on the paramecium delivery pipe 104. A feed outlet and a water outlet are connected to the breeding tank 103. A water quality sensor 107 is used to monitor the water quality in real time. When the water quality is lower than the set value, automatic water replacement is implemented. This technical solution divides the zebrafish fry breeding pond 1 into multiple breeding areas through feeding pipes, divides the zebrafish fry into small units for breeding, and then feeds them in different areas to ensure that the zebrafish fry in the small units have enough food, thereby improving the feeding quality of the zebrafish fry. The water quality sensor 107 is used to monitor the water quality in real time. When the water quality after filtration is still not up to standard, automatic water replacement is implemented to ensure the breeding water quality of the zebrafish fry.

[0055] like Figure 1 , Figures 6-8As shown, a bottom tank 6 is installed at the bottom of the zebrafish fry rearing pond 1. A mesh plate 110 is installed at the connection between the bottom tank 6 and the zebrafish fry rearing pond 1. The bottom tank 6 is connected to the zebrafish fry rearing pond 1 through the mesh of the mesh plate 110. When the yeast powder in the rearing water of the zebrafish fry rearing pond 1 settles, it will fall into the bottom tank 6. Several zebrafish fry rearing net cages 111 are placed on the mesh plate 110. Several impurity storage tanks 112 are set at the bottom of the bottom tank 6 to collect the settled yeast powder and impurities. The bottom of the discharge trough 112 is arc-shaped. One end of the impurity storage trough 112 is connected to an impurity conveying pipe 603. The bottom of the impurity conveying pipe 603 and the arc-shaped impurity storage trough 112 are concentric. A reduction gearbox B601 is installed at one end of the impurity conveying pipe 603, and a motor B602 is installed on the reduction gearbox B601. An auger A604 is installed inside the impurity storage trough 112. One end of the auger A604 passes through the impurity conveying pipe 603 and is fixedly connected to the gear inside the reduction gearbox B601. A water outlet pipe 605 is installed on the impurity conveying pipe 603, and a motor is installed on the water outlet pipe 605. When the aquaculture water needs to be changed, the electromagnetic valve simply activates motor B602. Motor B602 rotates forward, driving the gears inside the reduction gearbox B601, which in turn rotates the auger A604. This causes the settled yeast powder to be lifted from the bottom of the impurity storage tank 112, and the yeast powder is discharged through the outlet pipe 605 along with the water flow. When only aquaculture water purification is needed, motor B602 rotates in reverse, using the reverse rotation of auger A604 to lift the settled yeast powder and impurities from the bottom, then pumping the water containing yeast powder and impurities into the filter box. The aquaculture pond water filtration box 2 is used to filter the water and collect yeast powder and impurities. This technical solution involves setting up a bottom tank 6 at the bottom of the zebrafish fry rearing pond 1, which is connected to the zebrafish fry rearing pond 1. This bottom tank can collect the yeast powder that has settled in the rearing water. By controlling the forward and reverse rotation of the motor B602, the auger A604 can stir up the settled yeast powder when changing or purifying the water. This makes it easy to discharge the yeast powder when changing the water and to draw it into the aquaculture pond water filtration box 2 for collection and treatment when purifying the water.

[0056] like Figure 6 and Figure 9As shown, the top of the zebrafish fry rearing net cage 111 is threaded with a net cage cover 1111 for easy opening and removal of zebrafish fry later. The bottom of the zebrafish fry rearing net cage 111 is threaded with a counterweight base 1113 to increase weight and prevent movement. The counterweight base 1113 can also be fixed to the net plate 110. A net cage hole cleaning ring plate 1114 is fitted in the middle of the zebrafish fry rearing net cage 111. Several mesh holes are evenly arranged around the perimeter of the fish rearing net cage 111. Cleaning bristles are provided on the contact surface between the net cage hole cleaning ring plate 1114 and the mesh holes 1112. Electric lifting rods 101 are installed at the four corners of the zebrafish fry rearing pond 1. A top frame 102 is installed on the top of the electric lifting rods 101. Several connecting rods 109 are installed on the net cage hole cleaning ring plate 1114. One end of the connecting rod 109 is welded to the top frame 102. The electric lifting rods 101... 01. The top frame 102 is raised and lowered, which in turn drives the connecting rod 109 to rise and fall. The rising and falling of the connecting rod 109 in turn drives the raising and falling of the net cage hole cleaning ring plate 1114. The cleaning brushes on the inner side of the net cage hole cleaning ring plate 1114 clean the mesh holes around the zebrafish fry rearing net cage 111 during the raising and falling process, preventing blockage and affecting the entry of paramecia into the zebrafish fry rearing net cage 111, thereby further improving the rearing quality of zebrafish fry. In this technical solution, during the feeding process of zebrafish fry, the electric lifting rod 101 is activated. The up and down movement of the electric lifting rod 101 allows the brushes on the inner side of the net cage hole cleaning ring plate 1114 to clean the mesh holes around the zebrafish fry rearing net cage 111, preventing the mesh holes from being blocked. This facilitates the smooth entry of paramecia into the zebrafish fry rearing net cage 111, improving the quality of automatic feeding.

[0057] like Figure 1 and Figure 10As shown, the top of one end of the feeding box 3 for paramecium farming has a paramecium mother liquor inlet 302 for convenient periodic addition of paramecium mother liquor. The top of the other end of the feeding box 3 is connected to an automatic yeast powder feeding device 301. The automatic yeast powder feeding device 301 includes a yeast powder conveying pipe 306 connected to the feeding box 3 for paramecium farming. A motor C303 is installed on the top of the yeast powder conveying pipe 306. The main shaft of the motor C303 is connected to an auger B307 located inside the yeast powder conveying pipe 306 via a coupling. A yeast powder storage hopper 304 is welded to the outer periphery of the yeast powder conveying pipe 306. A yeast powder inlet 305 is provided on the side of the yeast powder conveying pipe 306 inside the yeast powder storage hopper 304. The yeast powder storage hopper 304 is filled with yeast powder. The speed of the motor C303 can be controlled by a frequency converter, thereby controlling the feeding speed of the yeast powder and ensuring a certain amount of paramecium nutrient raw material (yeast powder) is supplied. This technical solution adds a raw material feeding device for cultivating paramecium to the path of water purification, recycling and reuse. The purified and reused water flow allows the paramecium raw material to enter the paramecium breeding tank 5 along with the purified water, making the feeding of raw materials during the cultivation of paramecium simpler and more convenient.

[0058] like Figure 1 and Figure 3 As shown, the interior of the paramecium grading rearing box 4 consists of several paramecium rearing tanks 403 of different depths. The height difference between any two adjacent paramecium rearing tanks 403 is the same. These tanks with the same height difference are connected by a connecting pipe 404 equipped with a solenoid valve B405. The stepped arrangement of the paramecium rearing tanks 403 allows the paramecia in each step to be of different sizes. When the paramecia in the last step are transported to the rearing pool for feeding, the paramecia in the adjacent step above the last step are transported to the next step. All the paramecia in the stepped rearing tanks flow to the next step. In this tiered rearing system, when the zebrafish fry need to be fed again after a period of time, the paramecia in the last tier of the rearing tank will also be grown to a suitable size, providing a sufficient amount of paramecia for the zebrafish fry. This prevents the distribution of paramecia of different sizes to the zebrafish, which would cause uneven feeding. The tiered rearing method ensures that the paramecia in each paramecia rearing tank 403 are of uniform size and that the supply of paramecia food is guaranteed. The number of paramecia in each paramecia rearing tank 403 can also be adjusted according to the growth of the zebrafish fry. By increasing the amount of liquid entering the paramecia rearing tank 403 from the paramecia rearing tank 5, the number of paramecia will also increase.

[0059] The specific operation is as follows: When it is necessary to feed the zebrafish fry rearing pond 1, open the solenoid valve A402. The paramecia in the deepest paramecia rearing tank 403 of the paramecia grading rearing box 4 are transported along with the water through the paramecia feed pipe 401 to the paramecia delivery pipe 104, and then discharged through the outlet of the paramecia delivery pipe 104 to feed the zebrafish fry. After feeding is completed, the solenoid valve A402 is closed, and the paramecia grading rearing box 4 is opened from bottom to top. First, open the solenoid valves B405 on the connecting pipe 404 in sequence. Due to gravity, the paramecia in the upper-level paramecium rearing tank 403 flow with the water into the lower-level paramecium rearing tank 403. When all the paramecia from the upper level have entered the lower-level paramecium rearing tank 403, close the solenoid valve B405 of the upper level, and then open the solenoid valve B405 of the level before that, allowing the paramecia from the level before that to flow with the water. Water enters the paramecium rearing tank 403 of the previous level to prevent paramecia from entering the next level's tank. This process continues until paramecia from each level are transferred to the next level's tank. Then, solenoid valve C407 is activated, allowing the paramecia in the rearing tank 5 to enter the top-level tank 403 along with the water. The opening and closing time of the solenoid valve can be set and controlled by a timer and controller. This technical solution uses paramecia rearing tanks 403 of different depths to achieve tiered rearing of paramecia, ensuring that the paramecia provided to the zebrafish fry rearing pond 1 are of uniform size. This results in a more even and sufficient supply of feed for the zebrafish fry. Tiered rearing also allows the paramecia sufficient growth time and avoids mixing paramecia of different sizes, which could cause some smaller paramecia to be prematurely fed as food, thus increasing the cost of the mother liquor.

[0060] like Figure 1 , Figure 11 and Figure 12As shown, the paramecium rearing tank 5 includes a top plate 514 welded to several water supply pipes 503, a filter inner cylinder 504 fixed inside the paramecium rearing tank 5, and a filter inner cylinder cleaning device 506 inserted into the filter inner cylinder 504. Several water supply pipes 503 fix the top plate 514 to the top of the paramecium rearing tank 5, and the outlets of the several water supply pipes 503 are all aligned with the filter inner cylinder 504. When the connecting pipe B511 delivers purified water containing paramecium mother liquor and yeast powder into the water supply pipes 503, the water is then... The water outlet of the water supply pipe 503 directly delivers water to the interior of the filter inner cylinder 504, achieving automatic feeding. A reduction gearbox A502 is installed at the top center of the top plate 514. A motor A501 is installed on the top of the reduction gearbox A502. A rotating shaft 507 is connected to the bottom of the reduction gearbox A502. Several stirring rods 508 are evenly welded to the circumference of the rotating shaft 507. The motor A501 drives the gears inside the reduction gearbox A502 to rotate, thereby driving the rotating shaft 507 to rotate. The rotation of the rotating shaft 507 drives the stirring rods 508 to rotate. The mixing of the yeast powder with the filter cylinder 504 ensures its complete dissolution in the water, providing nutrients for the paramecia. Four filter cylinder cleaning devices 506 are evenly welded onto the rotating shaft 507. A density sensor is installed on the inner wall of the paramecium rearing tank 5 to monitor the rearing density of the paramecia in real time. Several filter holes 509 are evenly arranged around the periphery of the filter cylinder 504. This technical solution uses high-pressure water to transport the paramecium mother liquor and yeast powder into the filter cylinder 504. High-speed stirring with a stirring rod ensures the yeast powder is fully dissolved in the water. This further enhances the dissolution effect of the yeast powder when the purified water containing the yeast powder is transported through the pipeline. While stirring the liquid, the filter cylinder 504 also prevents undissolved yeast powder and paramecia from being transported to the zebrafish fry rearing pond 1. During stirring, a significant amount of yeast powder adheres to the filter holes of the filter cylinder 504. Therefore, the filter cylinder cleaning devices 506 clean the filter holes simultaneously with stirring, increasing the dissolution rate of the yeast powder and preventing filter blockage.

[0061] like Figure 12As shown, the filter inner cylinder cleaning device 506 is L-shaped. A slot 5061, which can be inserted into the filter inner cylinder 504, is provided in the middle of the filter inner cylinder cleaning device 506. Brush plate mounting slots 5063 are provided on both sides of the slot 5061, and brush plates 5062 are installed in the brush plate mounting slots 5063. The slot 5061 on the filter inner cylinder cleaning device 506 is inserted into the filter inner cylinder 504, allowing the brush plates 5062 on both sides of the slot 5061 to fit snugly against the filter inner cylinder 504. When the rotating shaft 507 rotates, the brush plates... The brush plate 5062 also rotates, causing the brushes on the brush plate 5062 to rub against the filter holes 509 on the filter inner cylinder 504, thereby cleaning the filter holes 509 and increasing the friction between the brushes and the yeast powder attached to the filter holes 509, thus improving the dissolution effect of the yeast powder. This technical solution cleans the filter inner cylinder 504, which not only removes the yeast powder clogging the filter holes and allows the paramecia to exit from the filter inner cylinder 504, but also increases the dissolution rate of the yeast powder attached to the filter holes.

[0062] like Figure 2 , Figure 3 and Figure 13 As shown, a control box 7 is installed on the paramecium grading and rearing box 4, and a control panel is installed on the control box 7. A water supply pipe 8 is connected to the zebrafish fry rearing pond 1, and an electromagnetic valve is also installed on the water supply pipe 8.

[0063] The control box 7 is equipped with a timer and a controller. The timer is electrically connected to the electric lifting rod 101, centrifugal pump A510, centrifugal pump B513, solenoid valve A402, solenoid valve B405, solenoid valve C407, motor A501, motor B602 and motor C303 through the controller.

[0064] The water quality sensor 107 is electrically connected to the solenoid valves, motor B602, centrifugal pump A510, and centrifugal pump B513 on the water supply pipe 8 and the water outlet pipe 605 respectively via the controller. The water quality sensor 107 monitors the aquaculture water in real time. When the sensor detects that the water quality reaches the set threshold, the centrifugal pumps A510 and B513 are turned on to circulate and purify the water. When the water quality is lower than the set threshold, the solenoid valves on the water supply pipe 8 and the water outlet pipe 605 are turned on directly to change the water in the zebrafish fry rearing pond 1.

[0065] The density sensor is electrically connected to the centrifugal pump A510 and the alarm installed on the control box 7 via the controller. When the paramecium breeding density is too low, an alarm is triggered. The staff adds paramecium mother liquor, and under the action of the centrifugal pump A510, the paramecium mother liquor and yeast powder are transported into the paramecium breeding tank 5 to increase the paramecium breeding density.

[0066] Working principle: such as Figure 1-13As shown, an automatic zebrafish fry feeding device allows operators to set the feeding time for zebrafish fry and use a timer. When the feeding time arrives, the controller opens the solenoid valve A402, allowing water containing paramecia to be transported through the paramecia feed pipe 401 to the paramecia conveying pipe 104. The water is then discharged through the outlet on the paramecia conveying pipe 104 to various breeding areas, feeding the zebrafish fry breeding net cages 111 in each area. Simultaneously, the electric lifting rod 101 drives the net cage hole cleaning ring plate 1114. Clean the zebrafish fry rearing net cage 111 to allow paramecia to enter the zebrafish fry rearing net cage 111. After feeding is completed, the controller closes the solenoid valve A402 and then controls the solenoid valves B405 at different positions in the paramecia graded rearing box 4 to open and close at different times, thereby completing the flow of paramecia in the paramecia rearing tank 403 of the upper step to the paramecia rearing tank 403 of the lower step. Then close the solenoid valve B405 and open the solenoid valve C407, so that the water in the paramecia rearing tank 5 flows into the paramecia rearing tank 403 at the top.

[0067] Then, the controller controls the operation of motor B602, centrifugal pump A510, and centrifugal pump B513. Motor B602 drives the auger A604 to rotate in the opposite direction, thereby stirring up the small amount of yeast powder that has settled in the impurity storage tank 112. At the same time, centrifugal pump A510 works to transport the culture water containing impurities and yeast powder in zebrafish fry culture pond 1 to the culture pond water filter box 2 for purification. The purified culture water is then transported to the paramecium culture feeding box 3, which carries the yeast powder that is automatically added by motor C303 and the paramecium mother liquor that is manually added, and transports them together to the paramecium culture tank 5 for culture. In the paramecium culture tank 5, motor A501 is powered on to drive the stirring rod 508 to stir the yeast powder. At the same time, the filter inner cylinder cleaning device 506 is used to clean the filter inner cylinder 504 to prevent clogging of the paramecium and to increase the speed of yeast powder dissolution.

[0068] When there is excess culture medium in the paramecium rearing tank 5, the water that has passed through the yeast powder filter box 505 is transported to the return water pipe 105 by the centrifugal pump B513. The water is then sprayed out through the outlet of the return water pipe 105 to increase the oxygen concentration of the rearing water. The yeast powder filter box 505 filters the excess water in the paramecium rearing tank 5, and a large amount of yeast powder in the water is filtered out. Some paramecia in the water will be transported to the rearing pond and can also be eaten by zebrafish fry, thus avoiding waste.

[0069] When it is necessary to purify the water in zebrafish fry rearing pond 1, centrifugal pumps A510 and B513 can be turned on directly. There is no need to add paramecium mother liquor and yeast powder. The water is continuously circulated and purified through the rearing pond water filter box 2 and the yeast powder filter box 505, thereby improving the quality of the rearing water.

[0070] The above embodiments merely illustrate implementation methods of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
