[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The monitoring unit monitors the number of fry in the release area, and the control unit controls the feed delivery frequency of the feed feeder according to the monitored number of fry. Driven by compressed gas, the feed in the feed feeder falls from the discharge end into the support shell with the help of the drainage tube, and then is discharged into the upper water layer of the aquaculture pond with the help of a number of discharge holes, thereby realizing the automatic feeding of the feed. The barrier net provided can block the feed entering the pond water to prevent the feed from continuously sinking to the bottom of the pond, thereby affecting the feeding of the fry. As the number of fry increases, the feed delivery frequency of the feed feeder is also accelerated, shortening the interval between each feed delivery, thereby increasing the feed content in the pond. In order to prevent a large amount of feed from falling onto the barrier net before being eaten by the fry, resulting in a large amount of feed being accumulated on the barrier net, and the fry need to concentrate on the barrier net to eat, affecting the feeding efficiency, a trigger mechanism of an auxiliary mechanism is set.

[0016] 2. When the feed delivery frequency P n When the frequency is greater than the preset frequency P0, the control unit starts the water pump, which transports the water under the pool to each drainage tube through the water storage pipe and sprays it upward through multiple nozzles. The rising water flow generated by the upward spraying can better drive the feed particles, making them suspended in the water for a longer time, and the rising water flow can promote the feed to be evenly distributed in the water, reduce the occurrence of concentrated accumulation of feed on the barrier net, so that more fry can contact the feed, and improve the utilization rate of the feed. By controlling the operation of the rotating parts, the rotating parts drive the drainage tube to rotate, thereby expanding the range of the water flow rise and ensuring the whole release There is water flow in the area, which can significantly prolong the suspension time of feed in the water and improve feed utilization. It should be noted that the intensity of the water flow that drives the feed upward is mild, such as small flow and low pressure, which is unlikely to scare away the fry. On the contrary, it may attract the fry to approach the feeding area, stimulate the foraging behavior of the fry, and increase their feeding enthusiasm. The drainage tube is designed to rotate to avoid the situation where the water flows vertically upward at a certain position, which may cause discomfort to the fry. The gradient linear array distribution of the nozzles on the drainage tube can ensure that the water flow is evenly distributed over a larger range.

[0017] 3. Compared with the traditional feeding method, the auxiliary mechanism of the present application has significant advantages. In the traditional method, the feed sinks quickly after being directly thrown into the water, resulting in a large amount of waste and easily causing water pollution. The design of the present application not only prolongs the suspension time of the feed by generating an upward water flow field, but also promotes the uniform distribution of the feed, greatly improving the utilization rate of the feed. At the same time, the movement of the water flow simulates the natural environment, which is conducive to stimulating the growth and development of the fry. This design not only solves technical problems, but also has the advantages of saving resources and improving efficiency, reflecting a high degree of creativity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figures 1 to 7 The automatic feeding device for fish fry breeding shown in the figure comprises a support shell 1, on the surface of which a plurality of floating platforms 3 are fixedly connected via a mounting frame 2, and further comprises: A feed feeder 4 is fixedly mounted on the top of the support shell 1. The discharge pipe of the feed feeder 4 is fixedly connected to the inside of the support shell 1 through a drainage pipe 5. A plurality of discharge holes 6 are provided at the bottom of the support shell 1. The support frame 7 is arranged above the support shell 1 through a lifting mechanism, and the lifting mechanism is used to drive the support frame 7 to move vertically; Two cylinders 8 are symmetrically fixedly connected to the bottom of the support frame 7. A circular plate 9 is fixedly connected to the bottom of the two cylinders 8. Two installation openings are formed on the top of the circular plate 9. Two waterproof light strips 10 are respectively fixed and wound around the surfaces of the two cylinders 8 to attract the fry; Two barrier nets 11 are fixedly mounted on the inner walls of the two mounting openings respectively; The auxiliary mechanism is arranged below the circular plate 9 and is used to prolong the suspension time of the feed in the delivery area; A monitoring unit, arranged at the bottom of the supporting shell 1, is used to monitor the number of fry in the feed delivery area; The control unit controls the feed feeding device 4 to release the feed at a frequency P according to the number of fry monitored by the monitoring unit. n Control, feed delivery frequency P nWhen the frequency is greater than the preset frequency P0, the auxiliary mechanism is controlled to operate; when working, the basic framework of the device is formed by the support shell 1 and the mounting frame 2 with multiple floating platforms 3. After the floating platforms 3 are placed in the water, the support shell 1 is supported above the water surface by the buoyancy provided by the floating platforms 3. In actual use, the mounting frame 2 can be connected to the external azimuth adjustment rope, and the feed delivery point can be adjusted by pulling the rope. The circular plate 9 connected to the barrier net 11 is placed in the water through the lifting mechanism, and the waterproof light belt 10 is turned on at the same time. The light source emitted by the waterproof light belt 10 is used to attract the fry to gather at the feed delivery point to improve the feeding efficiency. The waterproof light belt 10 can be set to an intermittent flashing mode, which can not only attract the fry to gather, but also save energy. The monitoring unit monitors the number of fry in the delivery area, and the control unit controls the feed feeder 4 according to the monitored fry number results. Feed delivery frequency: the feed in the feed feeder 4 falls into the support shell 1 from the discharge end through the drainage pipe 5 under the drive of compressed gas, and then is discharged into the upper water layer of the culture pond water through a plurality of discharge holes 6, thereby realizing the automatic feeding of the feed. The barrier net 11 provided can block the feed entering the pond water to prevent the feed from continuously sinking to the bottom of the pond, thereby affecting the feeding of the fry. As the number of fry increases, the feed delivery frequency of the feed feeder 4 is also accelerated, shortening the interval between each feed delivery, thereby increasing the feed content in the pond. In order to prevent a large amount of feed from falling onto the barrier net 11 before being eaten by the fry, resulting in a large amount of feed being accumulated on the barrier net 11, and the fry need to concentrate on the barrier net 11 to eat, affecting the feeding efficiency. Therefore, a trigger mechanism of an auxiliary mechanism is set. When the feed delivery frequency P n When the frequency is greater than the preset frequency P0, the control unit will control the auxiliary mechanism to operate, prolong the suspension time of the feed, improve the feeding efficiency of the fry, and solve the problem of rapid sinking of the feed; in general, the automatic feeding device of the present application effectively solves the accuracy and efficiency problems of feed feeding in sea bass fry farming by comprehensively using technical means such as intelligent monitoring, dynamic regulation, and prolonging the suspension time of the feed, providing a more advanced and reliable feed feeding solution for fry farming.

[0029] For example, in an actual application scenario, the automatic feed feeding device of the present application is installed in a perch fry breeding pond with an area of ​​500 square meters and a water depth of 2.5 meters. Six floating platforms 3 are fixedly connected to the surface of the support shell 1 through a mounting frame 2. The buoyancy of each floating platform 3 is 50 kilograms, ensuring that the entire device can stably float on the water surface. The feed feeder 4 is fixedly installed on the support shell 1, with a capacity of 50 liters, which can store enough feed for one day. The discharge pipe of the feed feeder 4 passes through a drainage pipe with a diameter of 3 cm. 5 is fixedly connected to the inside of the support shell 1. The bottom of the support shell 1 is provided with 20 discharge holes 6 with a diameter of 1 cm, which are used to evenly spread the feed into the water. The barrier net 11 is placed in the pool water through the lifting mechanism. Two waterproof light strips 10 are fixedly wound on the surface of the two cylinders 8 respectively. Blue light is used because blue light has a strong attraction to perch fry. The waterproof light strip 10 is set to an intermittent flashing mode, which can not only attract the fry to gather, but also save energy. The two barrier nets 11 are fixedly installed on the inner walls of the two installation ports respectively. The mesh size is 2.5mm. The size is 1.5 mm, which can effectively prevent the feed from scattering without affecting the water flow. The auxiliary mechanism is arranged under the circular plate 9, which can generate an upward water flow, suspend the feed particles in the water for 20 to 30 seconds, and significantly prolong the effective feeding time of the fry. The monitoring unit is arranged at the bottom of the support shell 1, and a high-definition underwater camera is used in conjunction with an image processing algorithm to count the number of fry every 8 seconds. The control unit selects a suitable frequency from the preset 6 feeding frequency gears according to the monitoring results. When the delivery frequency exceeds the preset value, the control unit will start the auxiliary mechanism to generate an upward water flow; through this design, the automatic feed feeding device of the present application can intelligently adjust the feed delivery frequency according to the actual number of fry, avoiding the problem of feed waste caused by fixed programs. At the same time, by prolonging the suspension time of the feed, the feeding efficiency of the fry is improved, and the problem of rapid sinking of the feed is solved. In practical applications, this intelligent and precise feed delivery method can increase the feed utilization rate by about 30% and reduce feed waste by about 25%.

[0030] Compared with the prior art, the automatic feeding device of the present application has significant advantages. Traditional feed feeding equipment usually adopts a fixed time and fixed dosage feeding method, which cannot be adjusted according to the actual situation of the fry. This method may lead to insufficient feed when the fry are active frequently, and excessive feeding and waste when the fry are less active. In contrast, the present application monitors the number of fry in real time and dynamically adjusts the feeding frequency, which more accurately meets the actual needs of the fry.

[0031] As an embodiment of the present invention, the inner bottom surface of the support shell 1 is fixedly connected with a conical shell 12 and a first motor 13, the first motor 13 is located inside the conical shell 12, and the output shaft end of the first motor 13 passes through the conical shell 12 and extends upward and is fixedly connected with a plurality of arc-shaped dispersion plates 14; when working, the feed falls into the support shell 1 from the discharge pipe of the feed feeder 4 through the drainage pipe 5, and when the feed contacts the rotating arc-shaped dispersion plate 14, it will be quickly broken up and thrown around, and the existence of the conical shell 12 further increases the dispersion range of the feed, so that the feed can be more evenly distributed in the water body, further increasing the dispersion range of the feed, and this structural design can significantly improve the dispersion effect of the feed in the water, so that the feed can be more evenly distributed in the water body; Traditional feeding devices usually simply throw feed directly onto the water surface. This method easily causes the feed to be concentrated in a small area, affecting the feeding of the fry, causing feed waste and water pollution. The present application introduces a conical shell 12 and a rotating arc-shaped dispersion plate 14 to achieve multi-stage dispersion of the feed, greatly improving the dispersion effect of the feed in the water, which not only reduces feed waste, but also allows more fry to come into contact with the feed, thereby improving the utilization rate of the feed. At the same time, the evenly dispersed feed also reduces competition between the fry, which is beneficial to the healthy growth of the fry.

[0032] As an embodiment of the present invention, the lifting mechanism includes two mounting seats 15, which are fixedly connected to the side wall of the support shell 1 in a circular array, and a round rod 16 is fixedly connected to the top of one of the mounting seats 15, and the round rod 16 is vertically slidably connected to the support frame 7, and a threaded sleeve is fixedly embedded on the support frame 7. A second motor 17 is fixedly installed at the bottom of the other mounting seat 15, and a threaded rod 18 is fixedly connected to the end of the output shaft of the second motor 17, and the threaded rod 18 is threadedly connected to the threaded sleeve on the support frame 7; when working, the second motor 17 is a forward and reverse stepping motor, and by starting the second motor 17, the output shaft of the second motor 17 will drive the threaded rod 18 to rotate, and the rotating threaded rod 18 drives the support frame 7 with the cooperation of the threaded sleeve, and under the connection of the two cylinders 8, the circular plate 9 connected with the barrier net 11 is placed in the pool water, so that in the process of feeding, it is convenient for the barrier net 11 to receive the feed in the feeding area, so as to prevent the feed from falling to the bottom of the pool, failing to meet the feeding needs of the fry, and causing feed waste.

[0033] As an embodiment of the present invention, the auxiliary mechanism includes: Two rotating plates 19 are rotatably connected to the bottom of the circular plate 9 in a circular array, and the bottoms of the two rotating plates 19 are commonly fixedly connected to a first fixed plate 20; The water pump 21 is fixedly mounted on the top of the first fixed plate 20. The end of the water inlet pipe of the water pump 21 is fixedly connected to a protective cover 22. The bottom of the protective cover 22 is fixedly connected to a filter screen 23. The water outlet pipe of the water pump 21 is fixedly connected to a water storage pipe 24. The surface of the water storage pipe 24 is fixedly connected to the side walls of the two rotating plates 19. The surface of the water storage pipe 24 is fixedly connected to a plurality of drainage tubes 25 in a circumferential array. A plurality of nozzles 26 are fixedly arranged on the surface of each drainage tube 25. The nozzles 26 on the drainage tubes 25 are distributed in a gradient linear array. The farther away from the water storage pipe 24, the smaller the spacing between the nozzles 26. The rotating component is arranged below the circular plate 9 and is used to drive the plurality of drainage tubes 25 to rotate. When the feed delivery frequency P n When the frequency is greater than the preset frequency P0, the control unit starts the water pump 21, and the water pump 21 transports the water under the pool to each drainage tube 25 through the water storage pipe 24, and sprays it upward through multiple nozzles 26. The rising water flow generated by the upward spraying can better drive the feed particles, so that they are suspended in the water for a longer time, and the rising water flow can promote the feed to be evenly distributed in the water, reduce the occurrence of concentrated accumulation of feed on the barrier net 11, so that more fry can contact the feed, and improve the utilization rate of the feed. By controlling the operation of the rotating component, the rotating component drives the drainage tube 25 to rotate, thereby expanding the range of the water flow rise, ensuring The entire delivery area has an upward water flow, which can significantly prolong the suspension time of the feed in the delivery area and improve the feed utilization rate. It should be noted that the intensity of the water flow that drives the feed upward is gentle, such as a small flow rate and low pressure, which is unlikely to scare away the fry, but may attract the fry to approach the feed area, which can stimulate the fry's foraging behavior and improve its feeding enthusiasm. The drainage tube 25 is designed to rotate to avoid the situation where the water flow continues to rise vertically at a certain position, which may cause the fry to feel uncomfortable. The gradient linear array distribution of the nozzle 26 on the drainage tube 25 can ensure that the water flow is evenly distributed in a larger range. The setting of the filter screen 23 effectively blocks impurities from entering the interior of the protective cover 22 when the water pump 21 sucks water, thereby ensuring the cleanliness of the jet water flow and preventing the impurities from causing damage to the fry.

[0034] Compared with the traditional feeding method, the auxiliary mechanism of the present application has significant advantages. In the traditional method, the feed sinks quickly after being directly thrown into the water, resulting in a large amount of waste and easily causing water pollution. The design of the present application not only prolongs the suspension time of the feed by generating an upward water flow field, but also promotes the uniform distribution of the feed, greatly improving the utilization rate of the feed. At the same time, the movement of the water flow simulates the natural environment, which is conducive to stimulating the growth and development of the fry. This design not only solves technical problems, but also has the advantages of saving resources and improving efficiency, reflecting a high degree of creativity.

[0035] As an embodiment of the present invention, the rotating component includes: An outer gear ring 27, the inner ring wall of which is fixedly connected to the ends of the plurality of drainage tubes 25; Two rotating shafts 28 are respectively located inside the two cylinders 8, and the surfaces of the two rotating shafts 28 are rotatably connected to the bottom of the cylinder 8 through sealed bearings; Two gears 29 are fixedly connected to the lower ends of the two rotating shafts 28, and the two gears 29 are meshed with the outer gear ring 27; The two third motors 30 are fixedly mounted on the top of the support frame 7, and the output shaft ends of the two third motors 30 extend to the inside of the two cylinders 8 respectively and are fixedly connected to the corresponding rotating shaft 28; when working, the control unit starts the third motor 30, and the output shaft of the third motor 30 drives the rotating shaft 28 connected to the gear 29 to rotate. Since the gear 29 is engaged with the outer gear ring 27 connected to the end of the drainage tube 25, the drainage tube 25 can be driven to rotate while the third motor 30 drives the gear 29 to rotate, which effectively prolongs the suspension time of the feed in the delivery area, and the rotation of the drainage tube 25 enhances the disturbance effect of the water flow, and also creates a dynamic feeding environment, which better simulates the food distribution state in natural waters and is conducive to stimulating the foraging behavior of fry.

[0036] As an embodiment of the present invention, a second fixing plate 31 is symmetrically fixedly connected to the bottom edge of the circular plate 9, and a cleaning knife 32 is fixedly installed on the side walls of the two second fixing plates 31; when working, an effective cleaning mechanism is formed by symmetrically arranging the second fixing plates 31 at the bottom edge of the circular plate 9 and fixing the cleaning knives 32 on the side walls of the two second fixing plates 31. This design mainly solves the problem that external debris adheres to the surface of the filter screen 23 during the water pumping process of the water pump 21, thereby affecting the flow performance of the filter screen 23. Through the designed cleaning knife 32, the cleaning knife 32 can The cleaning knife 32 can move closely along the periphery of the filter screen 23. When the auxiliary mechanism rotates, that is, when the first fixed plate 20 connected to the two rotating plates 19 rotates along the bottom of the circular plate 9, the cleaning knife 32 can effectively scrape off the debris attached to the surface of the filter screen 23, such as algae, scale, etc., and cleverly utilizes the movement of the existing structure without the need for an additional power source, thereby improving the energy efficiency of the entire device. In addition, the installation layout of the cleaning knife 32 can ensure the uniformity and comprehensiveness of the cleaning work, avoid the occurrence of cleaning dead corners, and at the same time, balance the forces generated during the cleaning process and reduce unnecessary interference to the auxiliary mechanism.

[0037] As an embodiment of the present invention, the monitoring unit includes a camera device and a computer terminal, the camera device captures video data of the fry, and the computer terminal analyzes and processes the data to realize automatic counting of the number of fry in the feed delivery area; Establish a range of fry numbers A in the control unit n and feed delivery frequency P n A database of corresponding relationships between When working, the monitoring unit in the technical solution realizes automatic monitoring and counting of the number of fry in the feed delivery area through the cooperation of the camera equipment and the computer terminal. The camera equipment is responsible for capturing the video data of the fry, while the computer terminal is responsible for analyzing and processing these data to obtain the accurate number of fry. The database established in the control unit stores the range of fry number A n and feed delivery frequency P n This enables the system to automatically adjust the feed delivery frequency P according to the monitored number of fry. n , realizing intelligent and precise control of feed delivery.

[0038] For example, the fry quantity range A1 can be set to 0-100, and the corresponding release frequency P1 is 1 time per minute; A2 can be set to 101-200, and the corresponding P2 is 2 times per minute, and so on.

[0039] like Figure 8 A control system of an automatic feeding device for fish fry breeding is shown, and the control system is specifically a control process of a control unit, and the control process includes the following steps: The monitoring unit monitors the number of fry in the feed delivery area and generates a range of fry number A n information; The monitoring unit will be the number of fry range A n The information is sent to the control unit to generate the feed delivery frequency P n The control unit controls the feeder 4 to deliver feed according to the corresponding frequency.

[0040] As an implementation mode of the present invention, the control process further includes: The control unit is based on the feed delivery frequency P n information, generating first control information and second control information; The control unit sends the first control information to the first motor 13 to control the first motor 13 to start, thereby driving the plurality of arc-shaped dispersion plates 14 to rotate; The control unit sends the second control information to the feeder 4 to control the feeder 4 to intermittently deliver the feed according to the corresponding time frequency.

[0041] As an implementation mode of the present invention, the control process further includes: The control unit sets the feed delivery frequency P n and the preset frequency P0 are substituted into the judgment formula P n> P0, if the judgment formula is not met, the auxiliary mechanism will not start and end the current process; if the judgment formula is met, the next process will be executed; The control unit generates third control information according to the judgment result; The control unit sends the third control information to the third motor 30 and the water pump 21 to control the water pump 21 to pump water, and controls the third motor 30 to drive the plurality of drainage tubes 25 to rotate.

[0042] Working principle of the present invention: the basic framework of the device is formed by a support shell 1 and a mounting frame 2 with multiple floating platforms 3. After the floating platforms 3 are placed in the water, the support shell 1 is supported above the water surface by the buoyancy provided by the floating platforms 3. In actual use, the mounting frame 2 can be connected to an external rope for adjusting the orientation, and the feed delivery point can be adjusted by pulling the rope. The circular plate 9 connected to the barrier net 11 is placed in the water through a lifting mechanism, and the waterproof light belt 10 is turned on at the same time. The light source emitted by the waterproof light belt 10 is used to attract the fry to gather at the feed delivery point to improve the feeding efficiency. The waterproof light belt 10 can be set to an intermittent flashing mode, which can not only attract the fry to gather, but also save energy. The monitoring unit monitors the number of fry in the delivery area, and the control unit controls the feed delivery frequency of the feed feeder 4 according to the monitored number of fry. Driven by compressed gas, the feed in the feeder 4 falls from the discharge end into the support shell 1 with the help of the drainage pipe 5, and then is discharged into the upper water layer of the culture pond water with the help of a plurality of discharge holes 6, thereby realizing the automatic feeding of the feed. The barrier net 11 provided can block the feed entering the pond water to prevent the feed from continuously sinking to the bottom of the pond, thereby affecting the feeding of the fry. As the number of fry increases, the feed delivery frequency of the feed feeder 4 is also accelerated, and the interval between each feed delivery is shortened, thereby increasing the feed content in the pond. In order to prevent a large amount of feed from falling onto the barrier net 11 before being eaten by the fry, resulting in a large amount of feed being accumulated on the barrier net 11, and the fry need to concentrate on the barrier net 11 to eat, affecting the feeding efficiency, a trigger mechanism of an auxiliary mechanism is set. When the feed delivery frequency P n When the frequency is greater than the preset frequency P0, the control unit will control the auxiliary mechanism to operate, prolong the suspension time of the feed, improve the feeding efficiency of the fry, and solve the problem of rapid sinking of the feed.
