[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figures 1-6 As shown, a multi-layer three-dimensional agronomic cultivation device includes a base 1, a rotating mechanism on the upper part of the base 1, an inner rotating shaft 13 and an outer rotating shaft 14 on the upper part of the rotating mechanism, the rotating mechanism drives the inner rotating shaft 13 and the outer rotating shaft 14, a cultivation trough 3 is provided on the upper part of the outer rotating shaft 14, a connecting shell 5 is fixedly connected to one side of the cultivation trough 3, the connecting shell 5 is rotatably connected to the inner rotating shaft 13, a sixth gear 20 is provided inside the connecting shell 5, the sixth gear 20 is fixedly connected to the inner rotating shaft 13, the sixth gear 20 is meshed with a seventh gear 21, and the upper part of the seventh gear 21... An eighth gear 22 is fixedly connected, and the eighth gear 22 meshes with a ninth gear 23. The ninth gear 23 is fixedly connected to a first transmission wheel 24. The first transmission wheel 24 is driven by a transmission belt 25. The transmission belt 25 is driven by a second transmission wheel 26. The second transmission wheel 26 is rotatably connected to the nutrient solution tank 2. The nutrient solution tank 2 is fixedly connected to the upper part of the cultivation trough 3. The second transmission wheel 26 is fixedly connected to a crank 27. The crank 27 is rotatably connected to a slider 28. The slider 28 is fixedly connected to a limit plate 30. A nutrient solution inlet 7 is opened on the side of the nutrient solution tank 2 near the cultivation trough 3.

[0021] Crops are planted inside cultivation trough 3. Activating the rotating mechanism drives the inner rotating shaft 13 and outer rotating shaft 14 to rotate. The rotation of the outer rotating shaft 14 causes the cultivation trough 3 to rotate, creating a centrifugal airflow field within the trough 3, promoting gas circulation and preventing root hypoxia and necrosis. The rotation of the inner rotating shaft 13 drives the sixth gear 20 to rotate, which in turn drives the second transmission wheel 26 to rotate. The second transmission wheel 26 then causes the limiting plate 30 to reciprocate. The upward movement of the limiting plate 30 connects the nutrient solution inlet 7 to the inside of the nutrient solution tank 2. Under the centrifugal force of the rotating nutrient solution tank 2, the nutrient solution is sprayed out from the inlet 7. During the rotation of the cultivation trough 3, the nutrient solution forms a parabolic liquid surface within the trough 3, automatically adding nutrient solution and achieving uniform coverage. Multiple nutrient solution tanks 2 are spirally arranged around the inner rotating shaft 13, with three inlet ports 7 on one side of each tank.

[0022] The nutrient solution tank 2 is fixedly connected to a slide rail 29, and a slider 28 is slidably connected to the upper part of the slide rail 29. The nutrient solution tank 2 is filled with sufficient nutrient solution. The cultivation trough 3 has an air groove 15 at the bottom, which is located at the root system of the crop. There are several air grooves 15. The upper part of the outer rotating shaft 14 is fixedly connected to a connecting rod 6, and the top of the connecting rod 6 is fixedly connected to the cultivation trough 3. The rotating mechanism includes a rotating housing 4 fixedly connected to the top of the threaded rod 10. The rotating housing 4 is equipped with a servo motor 16. The output end of the servo motor 16 is equipped with a rotating component. The rotation includes a third gear 17 set at the output end of the servo motor 16. A fourth gear 18 is meshed with one side of the third gear 17. The fourth gear 18 is meshed with a fifth gear 19. The upper part of the fifth gear 19 is fixedly connected to the outer rotating shaft 14. The outer rotating shaft 14 is rotatably connected to the rotating housing 4. The upper part of the third gear 17 is fixedly connected to an inner rotating shaft 13, which is rotatably connected to the outer rotating shaft 14.

[0023] In this embodiment, starting the servo motor 16 can drive the third gear 17 to rotate. The rotation of the third gear 17 drives the fourth gear 18 in the meshing rotating housing 4 to rotate. The rotation of the fourth gear 18 drives the fifth gear 19 in the meshing housing to rotate. The rotation of the fifth gear 19 can drive the fixedly connected outer rotating shaft 14 to rotate. The rotation of the outer rotating shaft 14 drives the fixedly connected cultivation trough 3 to rotate. The rotation causes the air in the cultivation trough 3 to form a centrifugal flow field, with the pressure on the outside being higher than that on the inside. This drives the air to flow from the center to the outer edge and then forms a circulation through the air groove 15 opened at the bottom of the cultivation trough 3. This effectively increases the contact between oxygen and the roots, while removing metabolic waste and preventing the roots from easily leading to anaerobic respiration due to lack of oxygen.

[0024] The rotation of the third gear 17 synchronously drives the inner rotating shaft 13 to rotate, which in turn drives the fixedly connected sixth gear 20 to rotate. The rotation of the sixth gear 20 causes the seventh gear 21, which is rotatably connected to the upper part of the connecting housing 5, to rotate. The rotation of the seventh gear 21 drives the fixedly connected eighth gear 22 to rotate, which in turn drives the meshing ninth gear 23 to rotate. The rotation of the ninth gear 23 drives the fixedly connected first transmission wheel 24 to rotate, which in turn drives the second transmission wheel 26, connected via the transmission belt 25, to rotate. The rotation drives the fixedly connected crank 27 to rotate, and the rotation of the crank 27 can drive the rotatingly connected slider 28 to move back and forth along the slide rail 29. The movement of the slider 28 can drive the fixedly connected limiting plate 30 to move up and down back and forth. When the limiting plate 30 moves up, it can release the obstruction of the liquid inlet 7. The nutrient solution inside the nutrient solution tank 2 can be automatically sprayed out from the liquid inlet 7 under the action of the centrifugal force of rotation, thereby acting on the surface of the crop. The centrifugal force generated by the rotation causes the nutrient solution to form a parabolic liquid surface in the cultivation tank 3. This liquid surface shape ensures that the nutrient solution evenly covers the surface of the crop under the action of centrifugation, effectively ensuring the effect of the nutrient solution.

[0025] Example 2 like Figures 1-6 As shown, an adjustment groove 8 is fixedly connected to the upper part of the base 1, and a threaded rod 10 is provided inside the adjustment groove 8. A rotating mechanism is fixedly connected to the upper part of the threaded rod 10, and an anti-slip surface is provided at the bottom of the base 1 to effectively ensure the stability of the device.

[0026] A first gear 11 is rotatably connected to one side of the adjusting groove 8. The first gear 11 is meshed with a second gear 12. The second gear 12 is threadedly connected to the threaded rod 10. An adjusting handle 9 is fixedly connected to the end of the first gear 11 away from the second gear 12.

[0027] In this embodiment, the cultivation troughs 3 are spirally arranged around the inner rotating shaft 13. The spiral structure effectively ensures that there is no obstruction from other cultivation troughs 3 above each cultivation trough 3, avoiding insufficient light for crops placed inside the lower cultivation trough 3. When the device is in use, rotating the adjustment handle 9 can also drive the fixedly connected first gear 11 to rotate. The rotation of the first gear 11 drives the meshing second gear 12 to rotate. The rotation of the second gear 12 can drive the threaded rod 10 to move up and down. During the movement of the threaded rod 10, the externally provided adjustment groove 8 can effectively ensure the stability of the threaded rod 10 during movement. The height of the cultivation trough 3 can be adjusted by the movement of the threaded rod 10, ensuring that the crops inside the cultivation trough 3 receive effective light.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
