The feeding hopper is arranged above one side of the mixing barrel, and the discharge pipe is fixedly arranged on one side of the mixing barrel. However, for this device, "the conveying gear is fixedly arranged on the output shaft of the conveying motor, and the conveying gear meshes with the conveying rack", the gear and the rack are exposed, and are more vulnerable to the erosion of the humid environment during the feeding process, requiring maintenance by operators, which affects the service life of this device. Summary of the Invention

During the feeding process, the main body of this device remains relatively stationary, the feeding landing point is fixed each time, and the feeding process is less likely to overturn, with better feeding stability. At the same time, the transmission mechanism is located inside the device, less vulnerable to the erosion of the humid environment during the feeding process, with a longer service life, good feeding stability, and does not require frequent maintenance.

[0004] The object of the present invention is achieved through the following technical solutions:

[0005] An automatic aquaculture feeding system includes a main feeding carrier platform, an upper feeding sealing cover, and floating cylinders. Both sides of the main feeding carrier platform have floating cylinder mounting platforms, the bottom of the floating cylinder mounting platforms is fixedly connected to the floating cylinders, the top of the main feeding carrier platform is fixedly connected to the upper feeding sealing cover. The main feeding carrier platform, the upper feeding sealing cover, and the floating cylinder connection body provide overall support for this device. The top of the upper feeding sealing cover is provided with a feeding mechanism, which provides overall feeding for this device. A conveying mechanism is arranged inside the main feeding carrier platform, and the conveying mechanism evenly conveys the feed provided by the feeding mechanism to various positions of the main feeding carrier platform. A feeding mechanism is arranged at the bottom of the main feeding carrier platform, and the feeding mechanism can evenly sprinkle the bait around to complete the feeding.

[0006] The conveying mechanism includes a positioning roller mounting bearing block, an auxiliary positioning roller, a conveying drive motor, a feeding conveyor belt, an upper feeding semi-cylinder, a lower feeding semi-cylinder, an inner limiting spring, a conveyor roller connecting bearing, and a feeding conveyor roller. The main feeding and loading platform internally has a lower bearing mounting platform, which is distributed at both ends of the main feeding and loading platform. One end of the upper feeding sealing cover has a motor mounting platform, which corresponds to the lower bearing mounting platform on one side. The other end of the upper feeding sealing cover has an upper bearing mounting groove, which corresponds to the lower bearing mounting platform on the other side. Multiple groups of conveyor roller connecting bearings are respectively inserted into the motor mounting platform, the upper bearing mounting groove, and the lower bearing mounting platform for fixation. The feeding conveyor rollers are arranged at both ends of the main feeding and loading platform, and both ends of the feeding conveyor rollers are fixedly connected to the inner rings of the conveyor roller connecting bearings at the corresponding positions. The top of the motor mounting platform is fixedly connected to the conveying drive motor, and the transmission shaft of the conveying drive motor is fixedly connected to the feeding conveyor roller at the corresponding position. The feeding conveyor belt is sleeved on the outer sides of the feeding conveyor rollers at both ends. The outer side of the feeding conveyor belt has a feeding cylinder partition plate. The space between adjacent feeding cylinder partition plates, together with the feeding conveyor belt and the inner wall of the main feeding and loading platform, forms a feeding cylinder limiting groove. The upper feeding semi-cylinder, the lower feeding semi-cylinder, and the inner limiting spring are all arranged inside the feeding cylinder limiting groove. The length and width of the feeding cylinder limiting groove are equal to the diameters of the upper feeding semi-cylinder and the lower feeding semi-cylinder. The bottom of the upper feeding semi-cylinder has a feeding cylinder connecting groove, which is adapted to the lower feeding semi-cylinder. The feeding cylinder connecting groove connects the lower feeding semi-cylinder and slides inside the lower feeding semi-cylinder. The inner limiting spring is sleeved on the outside of the feeding cylinder connecting groove, with the top of the inner limiting spring fixedly connected to the upper feeding semi-cylinder and the bottom of the inner limiting spring fixedly connected to the lower feeding semi-cylinder. The upper feeding semi-cylinder, the lower feeding semi-cylinder, and the inner limiting spring together form a feeding cylinder. The bottom of the lower feeding semi-cylinder is pressed against the bottom surface of the main feeding and loading platform, and the top of the upper feeding semi-cylinder is pressed against the lower part of the upper feeding sealing cover. The surface of the upper feeding sealing cover has auxiliary roller avoidance holes, which are evenly distributed on the surface of the upper feeding sealing cover. The top of the auxiliary roller avoidance holes is fixedly connected to the positioning roller mounting bearing block. The auxiliary positioning roller is arranged inside the main feeding and loading platform, and the top of the auxiliary positioning roller passes through the auxiliary roller avoidance hole and is fixedly connected to the inner ring of the positioning roller mounting bearing block. The auxiliary positioning roller is pressed against the inner side of the feeding conveyor belt.

[0007] Beneficial effects: 1. In the present invention, the feeding conveyor belt drives all the material conveying cylinders to move synchronously, thereby feeding all the material spreading cylinders synchronously, enabling all the material spreading cylinders to perform the feeding operation of feed synchronously. During the feeding process, the main body of this device remains relatively stationary, the dropping point of each feeding is fixed, and the device is less likely to overturn during the feeding process, with better feeding stability. At the same time, based on the precise nutritional requirements of fish farming, by adjusting the rotation speed of the material spreading drive motor, the feeding amount spilled by the material spreading cylinder is adjusted, facilitating the adjustment of the feed formula and the feeding amount, optimizing the feeding strategy of the feed according to the nutritional requirements at different breeding stages, thereby improving the feed utilization rate and the growth efficiency of aquatic animals, and ensuring the high quality of aquatic products. At the same time, the transmission mechanism is located inside the device, less vulnerable to the erosion of the humid environment during the feeding process, with a longer service life, good feeding stability, and no need for frequent maintenance.

[0008] 2. In the present invention, the synchronous drive shaft enables the feeding conveyor rollers and the synchronous feeding plates at corresponding positions to move synchronously, so that the upper material conveying semi-cylinders always remain relatively stationary with the synchronous feeding blocks at corresponding positions during the transmission process, ensuring that there is enough time for the feed to fill the upper material conveying semi-cylinders. At the same time, during the filling process, the feed accurately falls into the interior of the upper material conveying semi-cylinders without overflowing, ensuring the accuracy and stability of the feeding process.

[0009] 3. The upper material conveying semi-cylinders, lower material conveying semi-cylinders, and synchronous feeding blocks of the present invention are all made of plastic material. The plastic material is relatively soft. When the upper material conveying semi-cylinders, lower material conveying semi-cylinders, and synchronous feeding blocks rub against the upper feeding sealing cover and the main feeding bearing platform, the upper material conveying semi-cylinders, lower material conveying semi-cylinders, and synchronous feeding blocks themselves will be preferentially worn, thereby reducing the wear on the main feeding bearing platform and the upper feeding sealing cover, enabling the operator to only maintain the relatively small-sized upper material conveying semi-cylinders, lower material conveying semi-cylinders, and synchronous feeding blocks, avoiding frequent maintenance of the relatively large-sized and heavy main feeding bearing platform and the upper feeding sealing cover, and improving the maintenance convenience of this device.

[0010] 4. The main body of the material spreading cylinder of the present invention is designed in a cylindrical shape, and at the same time, an arc chamfer is provided on the outer side of the material spreading holes, so that the material spreading cylinder will not hit or scratch the fry coming to feed during its own rotation, improving the safety during the feeding process.

Multiple groups of conveying roller connecting bearings 31 are respectively inserted into the motor mounting platform 18, the upper bearing mounting groove 47, and the lower bearing mounting platform 37 for fixation. The feeding conveyor rollers 32 are arranged at both ends of the main feeding and loading platform 1, and both ends of the feeding conveyor rollers 32 are fixedly connected to the inner rings of the conveying roller connecting bearings 31 at corresponding positions.

The space between adjacent feeding cylinder partition plates 19, the feeding conveyor belt 21, and the inner wall of the main feeding and loading platform 1 together form a feeding cylinder limiting groove 48. The upper feeding semi-cylinder 22, the lower feeding semi-cylinder 23, and the inner limiting spring 24 are all arranged inside the feeding cylinder limiting groove 48.

The auxiliary positioning roller 14 is pressed against the inner side of the feeding conveyor belt 21.

[0030] Embodiment 3:

[0031] The feeding mechanism 5 of the present invention includes a feeding trough support frame 11, a feeding trough 17, a synchronous feeding plate 39, a synchronous drive shaft 41, and a synchronous feeding block 43. On one side of the upper bearing installation groove 47 of the upper feeding sealing cover 2, a feeding block docking groove 46 is provided. The feeding block docking groove 46 surrounds the outside of the upper bearing installation groove 47. The range of the feeding block docking groove 46 includes all the upper feeding half cylinders 22 at the turning point. The width of the feeding block docking groove 46 is smaller than the outer diameter of the upper feeding half cylinder 22 and larger than the inner diameter of the upper feeding half cylinder 22. At the top of the feeding conveyor roller 32 located on one side of the upper bearing installation groove 47, the synchronous drive shaft 41 is fixedly connected. At the top of the synchronous drive shaft 41, the synchronous feeding plate 39 is fixedly connected. At the bottom of the synchronous feeding plate 39, there is a synchronous feeding connection groove 42. The synchronous feeding connection grooves 42 are evenly arranged around the synchronous feeding plate 39. At the top of the synchronous feeding block 43, there is a synchronous feeding connecting rod 44. The synchronous feeding connecting rod 44 is adapted to the synchronous feeding connection groove 42. The synchronous feeding connecting rod 44 is connected to the synchronous feeding connection groove 42. The synchronous feeding connecting rod 44 slides inside the synchronous feeding connection groove 42. The upper limit spring 45 is sleeved outside the synchronous feeding connecting rod 44. The bottom of the upper limit spring 45 is fixedly connected to the synchronous feeding block 43. The top of the upper limit spring 45 is fixedly connected to the synchronous feeding connection groove 42. The synchronous feeding block 43 is adapted to the feeding block docking groove 46. The synchronous feeding block 43 at the corresponding position is connected to the feeding block docking groove 46. The synchronous feeding block 43 is inserted into the feeding block docking groove 46. The synchronous feeding block 43 connected to the feeding block docking groove 46 corresponds to the upper feeding half cylinder 22 at the turning point. At the upper part of the upper feeding sealing cover 2, the feeding trough support frame 11 is provided. At the bottom of the feeding trough support frame 11, there is a support frame mounting seat 12. The bottom of the support frame mounting seat 12 is fixedly connected to the upper feeding sealing cover 2. At the top of the feeding trough support frame 11, the feeding trough 17 is fixedly connected. The bottom opening of the feeding trough 17 corresponds to the synchronous feeding connection groove 42 of the synchronous feeding plate 39. The bottom of the feeding trough 17 is in contact with the synchronous feeding plate 39. The feeding trough 17 slides on the surface of the synchronous feeding plate 39.

[0032] Further, by placing the feed inside the feeding trough 17, the bottom of the feed contained in the feeding trough 17 is in contact with the synchronous feeding plate 39. The feed falls from the synchronous feeding connection groove 42 into the synchronous feeding block 43. When the bottom of the synchronous feeding block 43 contacts the surface of the upper feeding sealing cover 2 under the influence of the upper limit spring 45, the synchronous feeding block 43 seals itself, and the feed inside cannot fall. When the synchronous feeding block 43 is inserted into the feeding block docking groove 46 under the influence of the upper limit spring 45, the feed contained in the synchronous feeding block 43 falls into the material transfer cylinder, thus completing the feeding operation and facilitating the subsequent feeding operation of the conveying mechanism 6 for the feed.

[0033] It should be noted that the feeding conveyor roller 32 at the corresponding position and the synchronous feeding plate 39 are synchronously moved by the synchronous drive shaft 41, so that the upper feeding semi-cylinder 22 always remains relatively stationary with the synchronous feeding block 43 at the corresponding position during the transmission process, ensuring that the feed has sufficient time to provide filling for the upper feeding semi-cylinder 22. At the same time, the feed accurately falls into the interior of the upper feeding semi-cylinder 22 without overflowing during the filling process, ensuring the accuracy and stability of the feeding process.

[0034] Embodiment 4:

[0035] The spreading mechanism 7 of the present invention includes a spreading cylinder 15, a lower transmission cylinder 25, and a spreading drive motor 27. The bottom of the main feeding and supporting platform 1 has lower feeding communication holes 36, which are uniformly arranged at the bottom of the main feeding and supporting platform 1. The positions where the lower feeding communication holes 36 are opened correspond to the lower transmission semi-cylinders 23. The lower transmission cylinder 25 is fixedly connected to the bottom of the main feeding and supporting platform 1. The top opening of the lower transmission cylinder 25 corresponds to the position of the lower feeding communication holes 36. The bottom of the lower transmission cylinder 25 has an inner spreading cylinder mounting platform 26, and the top of the spreading cylinder 15 has an outer spreading cylinder mounting platform 28. The inner spreading cylinder mounting platform 26 is adapted to the outer spreading cylinder mounting platform 28. The inner spreading cylinder mounting platform 26 is connected to the outer spreading cylinder mounting platform 28, and the outer spreading cylinder mounting platform 28 rotates on the outside of the inner spreading cylinder mounting platform 26. The middle of the spreading cylinder 15 has a motor mounting shaft 29, and the middle of the lower transmission cylinder 25 has a spreading motor mounting platform 34. The spreading drive motor 27 is inserted and fixed inside the spreading motor mounting platform 34. The transmission shaft of the spreading drive motor 27 is fixedly connected to the motor mounting shaft 29. The side of the spreading cylinder 15 has spreading holes 33, and the spreading holes 33 are uniformly arranged around the spreading cylinder 15.

[0036] Furthermore, through the limitation of the inner limiting spring 24, the upper feeding semi-cylinder 22 is pressed against the lower part of the upper feeding sealing cover 2, and the lower transmission semi-cylinder 23 is pressed against the upper part of the bottom surface of the main feeding and supporting platform 1, ensuring that the connection body of the upper feeding semi-cylinder 22 and the lower transmission semi-cylinder 23 remains closed continuously when passing through the lower feeding communication holes 36 during the conveying process, avoiding feed leakage into the interior of the main feeding and supporting platform 1 and causing transmission system failures. Along with the feeding conveyor belt 21 driving the feeding cylinder to pass through each lower feeding communication hole 36 in turn, when the connection body of the upper feeding semi-cylinder 22 and the lower transmission semi-cylinder 23 corresponds to the lower feeding communication hole 36, the feed inside the upper feeding semi-cylinder 22 and the lower transmission semi-cylinder 23 passes through the lower feeding communication hole 36 and the lower transmission cylinder 25 in turn and finally falls into the interior of the spreading cylinder 15. Finally, along with the spreading drive motors 27 at each position driving the spreading cylinders 15 at the corresponding positions to rotate, the feed is spilled out from the spreading holes 33 of the spreading cylinders 15 to complete the feeding.

[0037] It should be noted that all the material transfer cylinders are driven to move synchronously by the feeding conveyor belt 21, so as to synchronously supply materials to all the feeding cylinders 15, enabling all the feeding cylinders 15 to perform the feeding operation of feed synchronously. During the feeding process, the main body of this device remains relatively stationary, the landing point of each feeding is fixed, and it is less likely to overturn during the feeding process, with better feeding stability. At the same time, the transmission mechanism is located inside the device and is less likely to be eroded by the humid environment during the feeding process, with a longer service life, good feeding stability, and no need for frequent maintenance.

[0038] It should also be noted that the upper material transfer half cylinder 22, the lower material transfer half cylinder 23, and the synchronous feeding block 43 are all made of plastic material. The plastic material is relatively soft, so when the upper material transfer half cylinder 22, the lower material transfer half cylinder 23, and the synchronous feeding block 43 rub against the upper feeding sealing cover 2 and the main feeding bearing platform 1, the upper material transfer half cylinder 22, the lower material transfer half cylinder 23, and the synchronous feeding block 43 themselves will be preferentially worn, thereby reducing the wear on the main feeding bearing platform 1 and the upper feeding sealing cover 2. This enables the operator to only maintain the relatively small-sized upper material transfer half cylinder 22, the lower material transfer half cylinder 23, and the synchronous feeding block 43, avoiding frequent maintenance of the relatively large-sized and heavy main feeding bearing platform 1 and the upper feeding sealing cover 2, and improving the maintenance convenience of this device.

[0039] It should also be noted that the main body of the feeding cylinder 15 is designed as a cylinder, and at the same time, an arc chamfer is provided on the outer side of the feeding hole 33, so that the feeding cylinder 15 will not bump or scratch the fry coming to feed during its own rotation, improving the safety during the feeding process. Based on the precise nutritional requirements of fish breeding, by adjusting the rotation speed of the feeding drive motor 27, the feeding amount spilled by the feeding cylinder 15 can be adjusted, facilitating the adjustment of the feed formula and the feeding amount, and being able to optimize the feeding strategy of the feed according to the nutritional requirements at different breeding stages, thereby improving the feed utilization rate and the growth efficiency of aquatic animals, and ensuring the high quality of aquatic products.

[0040] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and variations can be made, and these improvements and variations should also be regarded as the protection scope of the present invention.
