The upper casing limit platform has an upper gear ring mounting platform on the side, and the upper gear ring mounting platform is fixedly connected to the upper driven gear ring on the side. The outer rotating casing is fixedly connected to the lower driven gear ring on the side. The lower driven gear ring is located at the lower part of the upper casing limit platform. The radius of the lower driven gear ring is smaller than the radius of the upper driven gear ring. The floating bearing shell has a feeding motor platform on the side, and the side of the feeding motor platform is fixedly connected to the feeding drive motor.

[0010] 3. The dividing plate of the present invention slides inside the dividing plate installation groove, which can evenly transport the feed inside the dividing plate to various places inside the dividing plate installation groove, making the subsequent spreading operation more uniform. At the same time, the cooperation between the dividing plate and the feeding pipe can break up some large lumps of feed, making the feed falling into the dividing plate installation groove finer, avoiding clogging of the lower feeding trough and the upper feeding trough during subsequent feeding.

[0011] 4. After the device is placed at the feeding location, the lifting and traction motor is started, and the positioning anchor falls, providing overall positioning for the device, preventing the device from deviating from the feeding location after being disturbed by the outside world, and ensuring the feeding stability of the device. When the device needs to be recovered, the lifting and traction motor is started to raise the positioning anchor, and the device can be easily recovered at this time.

The sleeve docking groove 39 is adapted to the outer rotating sleeve 26, and the sleeve docking groove 39 is connected to the outer rotating sleeve 26. The outer rotating sleeve 26 rotates inside the sleeve docking groove 39.

[0027] Example 3:

[0028] The feeding drive device 102 of the present invention includes an active drive shaft 20, a material dividing plate carrying ring 24, an upper driven gear ring 30, a lower driven gear ring 33, and a feeding drive motor 38. The upper sleeve limit platform 27 has an upper gear ring mounting platform 28 on the side, and the upper gear ring mounting platform 28 is fixedly connected to the upper driven gear ring 30 on the side. The outer rotating sleeve 26 is fixedly connected to the lower driven gear ring 33 on the side. The lower driven gear ring 33 is located at the lower part of the upper sleeve limit platform 27. The radius of the lower driven gear ring 33 is smaller than the radius of the upper driven gear ring 30. The floating carrying shell 3 has a feeding motor platform 22 on the side, and the feeding motor platform 22 is fixedly connected to the feeding drive motor 38 on the side. The transmission shaft of the feeding drive motor 38 passes through the feeding motor platform 22 and is fixedly connected to the active drive shaft 20. The active drive shaft 20 has an external driving gear 36 on the side close to the feeding drive motor 38. The outer driving gear 36 is meshed with the upper driven gear ring 30, and the active drive shaft 20 has an inner driving gear 35 on the side away from the feeding drive motor 38. The inner driving gear 35 is meshed with the lower driven gear ring 33. The gear ring avoidance block 29 covers the active drive shaft 20, the upper driven gear ring 30, and the outer side of the lower driven gear ring 33. The side of the inner rotating tube 16 is fixedly connected to the dividing plate bearing ring 24. The dividing plate bearing ring 24 is located on the upper part of the gear ring avoidance block 29. The side of the dividing plate bearing ring 24 is provided with a dividing plate 25. The dividing plates 25 are evenly arranged around the dividing plate bearing ring 24. The gear ring avoidance block 29, the floating bearing shell 3, and the upper protective cover 4 together constitute the dividing plate mounting groove 23. The dividing plate mounting groove 23 is adapted to the dividing plate 25. The dividing plate mounting groove 23 is connected to the dividing plate 25, and the dividing plate 25 slides inside the dividing plate mounting groove 23.

[0029] Furthermore, an operating method of an aquaculture feeding device is provided. In the first step, during the feeding process, the feed is injected into the interior of the floating carrier shell 3 from the feeding pipe 21. In the second step, the feeding drive motor 38 is started at this time, and the feeding drive motor 38 drives the active drive shaft 20 to rotate. During the rotation of the active drive shaft 20, the upper driven gear ring 30 is driven to rotate through the external active gear 36. The rotation of the upper driven gear ring 30 drives the lower feeding ring 12 to rotate. The rotation of the lower feeding ring 12 drives the distribution plate 25 to rotate. The distribution plate 25 rotates the feeding pipe 21. The feed that falls inside is evenly dispersed into the mounting groove 23 of the dividing plate. During the rotation of the active drive shaft 20, the lower driven gear ring 33 is driven to rotate through the internal active gear 35. The rotation of the lower driven gear ring 33 drives the upper feeding ring 14 to rotate. When the feed continues to fall, it passes through the upper feeding ring 14 and is spread into the fish pond through the upper feeding trough 15 as the upper feeding ring 14 rotates. Part of the feed continues to fall and falls into the lower feeding ring 12. The lower feeding ring 12 rotates to spread the internal feed from the lower feeding trough 13 into the fish pond.

[0030] It should be noted that the radius of the upper driven gear ring 30 is larger than the radius of the lower driven gear ring 33, so that the rotation speed of the upper feeding ring 14 is higher than the rotation speed of the lower feeding ring 12, so that the upper feeding ring 14 located at the upper part can spread the internal feed to a larger range, and the lower feeding ring 12 located at the lower part can only spread the internal feed to a smaller range. Through the coordination of the spreading range of the lower feeding ring 12 and the upper feeding ring 14, this device can spread the feed over a wider range and more evenly, avoiding excessive concentration of feed and causing the farmed fish to scramble for food and get injured, thereby ensuring the breeding effect.

[0031] It should also be noted that the sides of the lower feeding trough 13 and the upper feeding trough 15 are both arc-shaped chamfered to prevent the lower feeding trough 13 and the upper feeding trough 15 from injuring the farmed fry when they come into contact with the farmed fry. At the same time, the lower feeding trough 13 and the upper feeding trough 15 are both V-shaped structures, which makes the resistance encountered by the lower feeding ring 12 and the upper feeding ring 14 during rotation smaller, thereby reducing the power consumption of the lower feeding ring 12 and the upper feeding ring 14 when feeding, and this device is more energy-efficient.

[0032] It should also be noted that the dividing plate 25 slides inside the dividing plate mounting groove 23, which can evenly transport the feed inside the dividing plate 25 to various places inside the dividing plate mounting groove 23, making the subsequent spreading operation more uniform. At the same time, the cooperation between the dividing plate 25 and the feeding pipe 21 can break up some large pieces of feed lumps, making the feed falling into the dividing plate mounting groove 23 more refined, avoiding clogging of the lower feeding trough 13 and the upper feeding trough 15 during subsequent feeding. The positioning anchor 11 is raised and lowered inside the inner rotating tube 16 to avoid external structures interfering with the feeding process. At the same time, the hidden storage of the rope around the reel 40 greatly reduces the risk of entanglement of the anchor body. This design shows unexpected stability in complex water environments. The present invention improves both energy saving and safety. The V-shaped structure and arc chamfer design of the feeding trough not only reduce the rotational resistance and save energy by about 20%, but also avoid scratching fish close to the device during high-speed rotation, which unexpectedly improves aquaculture safety. The closed design of the dividing plate mounting groove 23 and the gear ring avoidance block 29 effectively prevents feed from entering the transmission system and reduces mechanical wear.

[0033] Example 4:

[0034] The positioning mechanism 2 of the present invention includes a positioning anchor 11, a lifting and traction rope 17, a lifting and traction motor 19, and a rope winding reel 40. The upper protective cover 4 has an upper traction rope avoidance hole 37 inside, and the position of the upper traction rope avoidance hole 37 corresponds to the position of the inner rotating tube 16. The upper protective cover 4 has a feeding pipe 21 on the side, and the upper traction rope avoidance hole 37 has a lifting motor platform 18 on the side. The lifting motor platform 18 is fixedly connected to the lifting and traction motor 19 on the side. The transmission shaft of the lifting and traction motor 19 passes through the lifting motor platform 18 and is fixedly connected to the rope winding reel 40. A lifting and traction rope 17 is provided inside the inner rotating tube 16, and the bottom of the lifting and traction rope 17 is fixedly connected to the positioning anchor 11. The positioning anchor 11 passes through the inner rotating tube 16 from bottom to top and is wound around the outside of the rope winding reel 40.

[0035] It should also be noted that after the device is placed at the feeding location, the lifting and traction motor 19 is started, and the positioning anchor 11 falls, providing overall positioning for the device, preventing the device from deviating from the feeding location after being disturbed by the outside world, and ensuring the feeding stability of the device. After the device needs to be recovered, the lifting and traction motor 19 is started to raise the positioning anchor 11, and the device can be easily recovered at this time. The agglomeration breaking function extends the service life of the equipment and reduces the frequency of manual maintenance. The lifting and lowering of the positioning anchor 11 is controlled by the rope wrapped around the reel 40 to ensure that the device is fixed at the target position during feeding and quickly detached during recovery. It has strong resistance to wind and waves and water flow interference, avoiding feeding position deviation caused by drift. One-button anchoring and recovery, easy operation, and adaptable to complex fish pond environments. The present invention has high transmission efficiency and low energy consumption, especially with the V-shaped feeding trough design, which reduces rotational resistance and saves energy by about 20%. The dividing plate 25 not only undertakes the feed distribution function, but also can automatically break up agglomerated feed through sliding friction, solving the problem of feeding interruption caused by agglomeration blockage of traditional equipment, while improving feed utilization.

[0036] The upper and lower feeding rings create an "outward-expanding, inward-concentrating" feeding pattern: the centrifugal force generated by the high-speed rotation of the upper feeding ring disperses feed toward the edges of the pond, covering a wide area of ​​fish. The lower feeding ring, rotating at a lower speed, precisely feeds the densely populated center. This design, surprisingly, adapts to the feeding needs of fish of varying densities, making it particularly suitable for mixed-breeding ponds.

[0037] This device utilizes core technologies such as coordinated feeding between upper and lower feeding rings, dynamic feed distribution on the feed divider, and anchor fixation to achieve wide-area coverage, precise feeding, and energy-saving stability. Self-agglomeration improves feeding continuity; dual-ring complementary feeding accommodates diverse aquaculture scenarios; and a concealed positioning system enhances environmental adaptability. This significantly improves both the efficiency and safety of fish pond aquaculture.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
