[0006] Beneficial effects: 1. The present invention drives all the feeding barrels to move synchronously through the feeding conveyor belt, so as to synchronously feed all the spreading barrels, so that all the spreading barrels can synchronously perform the feeding operation of feed. During the feeding process, the main body of the device remains relatively still, and the landing point of each feeding is fixed.

[0007] 2. The present invention uses a synchronous driving shaft to make the feeding conveyor rollers at corresponding positions move synchronously with the synchronous feeding plate, so that the feeding half-cylinder always remains relatively still with the synchronous feeding block at the corresponding position during the transmission process, ensuring that there is enough time for the feed to fill the feeding half-cylinder.

When the upper feed half-cylinder, the lower feed half-cylinder and the synchronous feeding block rub against the upper feeding sealing cover and the main feeding bearing platform, the upper feed half-cylinder, the lower feed half-cylinder and the synchronous feeding block themselves will be worn first, thereby reducing the wear on the main feeding bearing platform and the upper feeding sealing cover, so that the operator only needs to maintain the smaller upper feed half-cylinder, the lower feed half-cylinder and the synchronous feeding block, and avoids frequent maintenance of the larger and heavier main feeding bearing platform and the upper feeding sealing cover, thereby improving the maintenance convenience of this device.

[0009] 4. The main body of the material spreading barrel of the present invention is cylindrical in design, and a circular chamfer is provided on the outward side of the material spreading hole, so that the material spreading barrel itself will not hit or scratch the fry coming to feed during the rotation process, thereby improving the safety of the feeding process.

[0026] Embodiment 3: The feeding mechanism 5 of the present invention comprises a feeding trough support frame 11, a feeding trough 17, a synchronous feeding plate 39, a synchronous driving shaft 41, and a synchronous feeding block 43. The upper feeding sealing cover 2 is provided with a feeding block docking groove 46 on one side of the upper bearing mounting groove 47. The feeding block docking groove 46 surrounds the outer side of the upper bearing mounting groove 47. The range of the feeding block docking groove 46 includes all the 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 feeding half cylinder 22 and larger than the inner diameter of the feeding half cylinder 22. The top of the feeding conveying roller 32 on one side of the upper bearing mounting groove 47 is fixedly connected to the synchronous driving shaft 41, and the top of the synchronous driving shaft 41 is fixedly connected to the synchronous feeding plate 39. The bottom of the synchronous feeding plate 39 has a synchronous feeding connecting groove 42, and the synchronous feeding connecting groove 42 is evenly arranged around the synchronous feeding plate 39.

The bottom opening of the feed trough 17 corresponds to the synchronous feeding connecting groove 42 of the synchronous feeding plate 39. The bottom of the feed trough 17 contacts with the synchronous feeding plate 39, and the feed trough 17 slides on the surface of the synchronous feeding plate 39.

[0027] Furthermore, by placing the feed inside the feed trough 17, the bottom of the feed contained in the feed trough 17 contacts the synchronous feeding plate 39, and the feed falls from the synchronous feeding connecting groove 42 into the synchronous feeding block 43. When the synchronous feeding block 43 is affected by the upper limit spring 45 and the bottom contacts the surface of the upper feeding sealing cover 2, the synchronous feeding block 43 itself is blocked and the internal feed cannot fall. When the synchronous feeding block 43 is affected by the upper limit spring 45 and inserted into the feed block docking groove 46, the feed contained in the synchronous feeding block 43 falls into the transfer barrel, thereby completing the feeding operation and facilitating the conveying mechanism 6 to carry out subsequent feed conveying operations.

[0028] It should be noted that the feeding conveyor roller 32 at the corresponding position is synchronized with the synchronous feeding plate 39 through the synchronous driving shaft 41, so that the feeding half-cylinder 22 always remains relatively still with the synchronous feeding block 43 at the corresponding position during the transmission process, ensuring that there is enough time for the feed to fill the feeding half-cylinder 22. At the same time, during the filling process, the feed falls accurately into the inside of the feeding half-cylinder 22 and will not overflow, ensuring the accuracy and stability of the feeding process.

[0029] Embodiment 4: The material spreading mechanism 7 of the present invention comprises a material spreading cylinder 15, a lower transmission cylinder 25, and a material spreading drive motor 27. The bottom of the main feeding bearing platform 1 is provided with a lower feeding connecting hole 36, and the lower feeding connecting holes 36 are evenly arranged at the bottom of the main feeding bearing platform 1. The opening position of the lower feeding connecting hole 36 corresponds to the lower material transmission half cylinder 23. The bottom of the main feeding bearing platform 1 is fixedly connected to the lower transmission cylinder 25, and the opening at the top of the lower transmission cylinder 25 corresponds to the position of the lower feeding connecting hole 36. The bottom of the lower transmission cylinder 25 is provided with an inner material spreading cylinder mounting platform 26, and the top of the material spreading cylinder 15 is provided with an outer material spreading cylinder mounting platform 28. The barrel mounting platform 26 is adapted to the outer barrel mounting platform 28, the inner barrel mounting platform 26 is connected to the outer barrel mounting platform 28, the outer barrel mounting platform 28 rotates outside the inner barrel mounting platform 26, the barrel 15 has a motor mounting shaft 29 in the middle, the lower transmission barrel 25 has a motor mounting platform 34 in the middle, the barrel 27 is inserted into the inside of the motor mounting platform 34 and fixed, the transmission shaft of the barrel 27 is fixedly connected to the motor mounting shaft 29, the barrel 15 has a scattering hole 33 on the side, and the scattering holes 33 are evenly arranged around the barrel 15.

[0030] Furthermore, the internal limit spring 24 is used to limit the feeding half cylinder 22 to the lower part of the upper feeding sealing cover 2, and the lower feeding half cylinder 23 to the upper part of the bottom surface of the main feeding supporting platform 1, to ensure that the connecting body of the upper feeding half cylinder 22 and the lower feeding half cylinder 23 remains closed when it does not pass through the lower feeding connecting hole 36 during the transportation process, to avoid feed leakage into the main feeding supporting platform 1 and cause transmission system failure, accompanied by the feeding conveyor belt 21 driving the feeding cylinder to pass through each lower feeding connecting hole 36 in turn, when the connecting body of the upper feeding half cylinder 22 and the lower feeding half cylinder 23 corresponds to the lower feeding connecting hole 36, the internal feed of the upper feeding half cylinder 22 and the lower feeding half cylinder 23 passes through the lower feeding connecting hole 36 and the lower transmission cylinder 25 in turn and finally falls into the spreading cylinder 15, and finally, accompanied by the spreading drive motor 27 at each position driving the spreading cylinder 15 at the corresponding position to rotate, the feeding is sprinkled out from the spreading hole 33 of the spreading cylinder 15 to complete the feeding.

[0031] It should be noted that all the feeding barrels are driven to move synchronously by the feeding conveyor belt 21, so as to synchronously feed all the spreading barrels 15, so that all the spreading barrels 15 can synchronously perform the feeding operation of feed. During the feeding process, the main body of the device remains relatively still, the landing point of each feeding is fixed, and the feeding process is less likely to overturn, and the feeding stability is better. At the same time, the transmission mechanism is stored on the inside of the device, which is less susceptible to erosion by the humid environment during the feeding process, has a longer service life, good feeding stability, and does not require frequent maintenance.

[0032] It should also be noted that the upper feed half-cylinder 22, the lower feed half-cylinder 23, and the synchronous feeding block 43 are all made of plastic material, which is relatively soft. When the upper feed half-cylinder 22, the lower feed 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 feed half-cylinder 22, the lower feed half-cylinder 23, and the synchronous feeding block 43 themselves will be worn first, thereby reducing the wear on the main feeding bearing platform 1 and the upper feeding sealing cover 2, so that the operator only needs to maintain the smaller upper feed half-cylinder 22, the lower feed half-cylinder 23, and the synchronous feeding block 43, and avoid frequent maintenance of the larger main feeding bearing platform 1 and the upper feeding sealing cover 2, thereby improving the maintenance convenience of this device.

[0033] It should also be noted that the main body of the spreading barrel 15 is cylindrical in design, and the outward side of the spreading hole 33 is provided with an arc chamfer, so that the spreading barrel 15 will not scratch the fry coming to feed during its own rotation, thereby improving the safety during feeding. Based on the precise nutritional needs of fish farming, the speed of the spreading drive motor 27 is adjusted to adjust the amount of feed sprinkled by the spreading barrel 15, which is convenient for adjusting the feed formula and feeding amount, and can optimize the feeding strategy of the feed according to the nutritional needs of different breeding stages, thereby improving the feed utilization rate and the growth efficiency of aquatic animals, and ensuring the high quality of aquatic products.

[0034] 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 a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
