[0025] The beneficial effects of the rice-throwing mechanism and system according to embodiments of the present invention include, for example:

[0026] This rice seedling throwing mechanism includes an installation module, a seedling releasing module, and a seedling picking module. The installation module is mounted on the drone, the seedling releasing module is mounted on the installation module and is used to transport the seedbed. The seedling picking module is mounted on the installation module and located above the seedling releasing module. The seedling picking module separates the seedlings from the seedbed on the seedling releasing module and throws them out. Because the seedling picking module generates significant vibration during the separation and throwing operation, in designs where the picking module is positioned below the seedling releasing module, the distance between the picking module and the drone is relatively large, and the vibration is amplified to the drone's fuselage through a long lever arm, affecting the drone's flight stability. In this design, because the seedling picking module is positioned above the seedling releasing module, the distance between the picking module and the drone is shortened, and the lever arm between them is also shortened. This reduces the vibration experienced by the drone during the separation and throwing operation, allowing the drone's fuselage to remain stable during flight and improving its flight stability and reliability.

[0027] This rice transplanting system includes a drone and at least one transplanting mechanism, with the mounting module mounted on the lower part of the drone. Because the seedling-collecting module generates significant vibration during the separation of the seedbed and transplanting operation, in designs where the seedling-collecting module is positioned below the seedling-releasing module, the distance between the seedling-collecting module and the drone is relatively large. This vibration is amplified to the drone's fuselage through a long lever arm, affecting the drone's flight stability. In this design, however, the seedling-collecting module is positioned above the seedling-releasing module, bringing it much closer to the drone. This shortens the distance between the two modules and reduces the lever arm, thereby reducing the vibration experienced by the drone during the separation of the seedbed and transplanting operation. This ensures the drone's stability during flight, improving its flight stability and reliability. Attached Figure Description

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] Drones are already widely used in agriculture. They can carry various operating systems and perform agricultural spraying and sowing operations. Currently, when using drones for rice transplanting, the transplanting mechanism is generally located at the bottom of the drone. The mechanism follows the drone as it flies above the farmland, transplanting the rice seedlings during flight.

[0042] The rice-throwing mechanism in the relevant technology has the problem that the vibration generated during the rice-throwing operation can affect the flight of the drone, resulting in poor flight stability of the rice-throwing mechanism.

[0043] Please refer to Figures 1-5 This embodiment provides a rice seedling throwing system 1000, which includes a drone 200 and at least one seedling throwing mechanism 100. The seedling throwing mechanism 100 is mounted on the lower part of the drone 200. The seedling throwing mechanism 100 separates the seedlings 101 from the substrate, and uses centrifugal force to throw the separated seedlings out or a catapult to launch them, thus achieving the seedling throwing operation. Simultaneously, it coordinates with the flight of the drone 200 to achieve aerial seedling throwing. This seedling throwing system 1000 can effectively improve the aforementioned technical problems, reduce the impact of vibration generated during seedling throwing on the flight of the drone 200, and improve the flight stability of the drone 200.

[0044] In this embodiment, the carrier is a drone 200, specifically an agricultural drone, which is generally equipped with spraying and sowing components required for agriculture, enabling spraying irrigation, sowing, and other functions. Of course, the carrier can also carry cameras, gaming devices, etc. Furthermore, the carrier is not limited to drone 200; for example, it can also be a robot, unmanned vehicle, unmanned boat, etc.

[0045] In this embodiment, the drone 200 is a rotary-wing drone, specifically a quadcopter drone. Of course, it can also be a single-rotor drone, a dual-rotor drone, a hexacopter drone, an octacopter drone, etc. The drone 200 can operate automatically according to a preset path, flight speed, attitude, etc., or it can be manually controlled by an operator.

[0046] Please refer to Figures 1-5 The seedling throwing mechanism 100 includes an installation module 10, a seedling releasing module 30, and a seedling picking module 20. The installation module 10 is installed on the drone 200. The seedling releasing module 30 is installed on the installation module 10 and is used to transport the seedlings 101. The seedling picking module 20 is installed on the installation module 10 and is located above the seedling releasing module 30. The seedling picking module 20 is used to separate the seedlings from the seedlings 101 on the seedling releasing module 30 and throw them out by centrifugal force or by ejection via a catapult.

[0047] Specifically, compared to placing the seedling-collecting module below the seedling-releasing module, when the UAV is equipped with the seedling-throwing mechanism, the seedling-collecting module rotates at high speed when separating the seedlings from the seedlings on the seedling-releasing module, generating significant vibrations that affect the flight stability of the UAV. In this embodiment, the seedling-collecting module 20 of the seedling-throwing mechanism 100 is located above the seedling-releasing module 30, making the seedling-collecting module 20 closer to the UAV 200 and its center of gravity closer to that of the UAV 200. This allows the UAV 200 equipped with the seedling-throwing mechanism 100 to fly more stably.

[0048] It should be noted that the seedling picking module 20 is located above the seedling releasing module 30. The "above" is only to indicate that the seedling picking module 20 is positioned higher in the height direction relative to the middle and lower parts.

[0049] In this embodiment, the installation module 10 includes a tripod 11 and a connector 12. The tripod 11 is located at the lower part of the drone 200, and the connector 12 connects the drone 200 and the tripod 11. The rice seedling release module 30 and the rice seedling picking module 20 are both located on the tripod 11.

[0050] In this embodiment, the seedling picking module 20 includes a drive source 23 and a cutter head 22. The drive source 23 is mounted on the stand 11 and connected to the cutter head 22. The drive source 23 drives the cutter head 22 to cut the seedlings 101 on the seedling release module 30. The seedlings are separated by cutting and then thrown out by centrifugal force. Alternatively, a catapult can be provided on the cutter head 22. During the rotation of the cutter head 22, the seedling needles of the cutter head 22 can cut off the seedlings and hold them in place to continue rotating. When the cutter head 22 rotates to a specific position, the catapult of the cutter head 22 is released and ejected, ejecting the seedlings held in place by the seedling needles, thus achieving seedling throwing.

[0051] Specifically, the drive source 23 is a motor, which drives the cutter head 22 to rotate, thereby separating the seedlings 101 during the contact process. The separated seedlings follow the rotation of the cutter head 22, and after rotating to a specific position, the seedlings are thrown out under the action of centrifugal force or ejector.

[0052] It should be noted that the cutter head 22 can be directly mounted on the output shaft of the drive source 23, with the drive source 23 directly driving the cutter head 22 to rotate. Alternatively, the cutter head 22 can be rotatably mounted on the mounting module 10, with the drive source 23 mounted on the mounting module 10 and connected to the cutter head 22 via a transmission mechanism, such as a gearbox, linkage mechanism, sprocket mechanism, or pulley mechanism, to provide driving force. Of course, the drive source 23 can also be a pneumatic motor or gasoline engine, instead of an electric motor.

[0053] In this embodiment, the seedling harvesting module 20 further includes a transmission box 21. A drive source 23 is connected to the transmission box 21 and is used to drive the transmission box 21 to rotate. Each transmission box 21 is equipped with at least one cutter head 22. The transmission box 21 can assign a specific motion trajectory to the cutter head 22. Generally, multiple meshing gears can be arranged inside the transmission box. The drive source 23 meshes with one of the gears in the transmission box 21, and the cutter head 22 meshes with another gear. The transmission box 21 can ensure that the motion trajectory of the cutter head 22 and the posture of the cutter head 22 during the motion process meet the requirements.

[0054] To improve seedling harvesting efficiency, the rotation speed of the cutter head 22 is usually increased. However, excessive speed may lead to other problems such as heat dissipation and unstable cutting. To solve this problem, in this embodiment, at least two cutter heads 22 are arranged on each transmission box 21, thereby expanding the number of cutter heads 22 at the same cutting and seedling throwing position.

[0055] In this embodiment, two cutter heads 22 are distributed on one transmission box 21. Of course, in other embodiments, only one cutter head 22, or three, four or more cutter heads 22 may be distributed. When two cutter heads 22 are distributed on one transmission box 21, the angle between the two cutter heads 22 and the center of the transmission box 21 can be 180 degrees. Three cutter heads 22 can be spaced 120 degrees apart, and four cutter heads 22 can be spaced 90 degrees apart. In other words, the cutter heads 22 can be arranged in a uniform distribution. Of course, it is not excluded that in some scenarios, the cutter heads 22 may be arranged in a non-uniform distribution.

[0056] By designing a larger number of cutter heads 22 on the transmission box 21, the seedling harvesting efficiency can be improved at the same rotational speed. Furthermore, in terms of installation, the transmission box 21 can be directly mounted on the output shaft of the drive source 23, or the transmission box 21 can be rotatably mounted on the mounting module 10, with the drive source 23 mounted on the mounting module 10 and connected to the transmission box 21 via a transmission mechanism, such as a gearbox, linkage mechanism, sprocket mechanism, or pulley mechanism, to provide driving force.

[0057] It should be noted that the seedling release module 30 includes a seedling release tray 31 and a seedling baffle plate 32. The seedling baffle plate 32 is connected to the installation module 10. The seedling baffle plate 32 is located above the seedling release tray 31, and the top of the seedling release tray 31 is located inside the seedling baffle plate 32. The seedling release tray 31 is slidably set on the installation module 10. The seedling release tray 31 can move laterally relative to the seedling baffle plate 32. The seedling baffle plate 32 has an opening. The seedling picking module 20 is used to separate the seedlings 101 on the seedling release tray 31 through the opening and to centrifugally throw out the separated seedlings or eject them with a catapult.

[0058] The seedling baffle 32 is positioned above the seedling tray 31 to block the seedlings 101 on the seedling tray 31 and prevent excessive seedlings 101 from protruding or falling from above the seedling tray 31.

[0059] Specifically, the openings and other positions of the seedling-releasing module 30 and the seedling-blocking plate 32 remain unchanged relative to the mounting module 10. The seedling-releasing tray 31 can reciprocate in the left-right direction. In this way, the seedling-releasing module 30 only cuts the seedlings 101 exposed in the opening, thus achieving row-by-row and bunch-by-bundle cutting and throwing of the seedlings 101. Of course, in other embodiments, the position of the seedling-releasing tray 31 relative to the mounting module 10 can remain unchanged, while the seedling-blocking plate 32 and the seedling-releasing module 30 can move laterally in the left-right direction.

[0060] In this embodiment, the rice seedling tray 31 is a rectangular plate structure.

[0061] Please refer to Figure 3 and Figure 4There are multiple seedling release modules 30, and the multiple seedling release modules 30 are respectively set on both sides of the installation module 10. The number of seedling take-up modules 20 corresponds one-to-one with the number of seedling release modules 30, and the multiple seedling take-up modules 20 are all set on the top of the installation module 10.

[0062] Specifically, to reduce the impact of the wind field from the UAV 200 on the seedling-collecting module 20 during seedling throwing, multiple seedling-collecting modules 20 are positioned at the center of the mounting module 10. This staggers the rotor positions of the seedling-collecting module 20 and the UAV 200, reducing the impact of the wind field generated by the rotor on the seedling-collecting module 20 during seedling throwing and improving the accuracy of seedling throwing. In other embodiments, the multiple seedling-collecting modules 20 may also be positioned at the edges of the mounting module 10.

[0063] In order to make better use of the space of the installation module 10, and in order to make the distance between adjacent seedlings smaller at the same rotation speed, the number of seedling release modules 30 in this embodiment is two, and the two seedling release modules 30 are symmetrically arranged along the height direction.

[0064] In other embodiments, the number of rice seedling release modules 30 may be increased or decreased, and no specific limitation is made here.

[0065] More specifically, the seedling release module 30 includes at least two seedling release trays 31 arranged side by side, the seedling baffle 32 has multiple openings, the number of openings corresponds one-to-one with the number of seedling release trays 31, and each seedling release tray 31 is provided with a seedling taking module 20 above it.

[0066] In this embodiment, the rice seedling release module 30 includes three seedling release trays 31, which are arranged side by side. This allows the drone 200 to complete multiple rows of seedling release operations in a single flight, improving seedling release efficiency. In other embodiments, the number of seedling release trays 31 in the rice seedling release module 30 may be increased or decreased, and no specific limitation is made here.

[0067] It should also be noted that the seedling picking module 20 also includes a synchronous shaft, which is connected to multiple drive sources 23. The multiple drive sources 23 are used to drive multiple cutter heads 22 to rotate synchronously through the synchronous shaft to ensure the accuracy of seedling throwing.

[0068] Furthermore, the seedling throwing mechanism 100 also includes a seedling delivery module 40, which is disposed on the mounting module 10. The seedling delivery module 40 is used to upwardly deliver the seedlings 101 on the seedling release module 30. Specifically, the seedling delivery module 40 includes a transmission component and a transmission motor. The transmission motor is connected to the mounting module 10, and the transmission component is connected to the transmission motor. The transmission component is used to upwardly deliver the seedlings 101 on the seedling release module 30.

[0069] Understandably, transmission belts or pulleys are selected as transmission components.

[0070] In this embodiment, there are multiple seedling delivery modules 40, which are arranged side by side.

[0071] It should be noted that multiple seedling delivery modules 40 can be set on the seedling release module 30, and the setting height of the multiple seedling delivery modules 40 can be different, so as to more reliably deliver seedlings upward.

[0072] Understandably, the seedling tray 31 has a connecting groove running through it, and the transmission component is connected to the seedling mat 101 on the seedling tray 31 through the connecting groove, thereby realizing the function of conveying the seedling mat 101 upward.

[0073] Furthermore, the rice seedling release module 30 is inclined to the mounting module 10, thereby reducing the space occupied by the rice seedling release module 30 in the horizontal width.

[0074] In this embodiment, the rice seedling release module 30 also includes a transverse drive source 60, which is connected to the rice seedling release tray 31. The transverse drive source 60 is used to drive the rice seedling release module 30 to reciprocate in the transverse direction.

[0075] Specifically, the transverse drive source 60 includes a transverse motor, a transverse gear, and a transverse rack. The transverse motor is installed on the mounting module 10, and the transverse motor and the transverse gear are connected. The transverse rack is set on the back of the seedling tray 31, and the transverse rack and the transverse gear mesh. The transverse gear rotates under the drive of the transverse motor, thereby driving the transverse rack to perform linear reciprocating motion, which in turn drives the seedling tray 31 to perform linear reciprocating motion.

[0076] In addition, the rice seedling release module 30 is equipped with a seedling pressing device 50, which is used to limit the position of the seedlings 101 inside the rice seedling release module 30.

[0077] Specifically, the seedling pressing device 50 includes a pressing strip 51 and a rotating shaft 52. The pressing strip 51 is arranged along the conveying direction of the seedling mat 101. The pressing strip 51 and the rotating shaft 52 are connected. The rotating shaft 52 is rotatably arranged on the seedling release module 30. The pressing strip 51 is used to press the seedling mat 101 under the force of the rotating shaft 52 to limit its position.

[0078] In addition, the seedling pressing device 50 also includes an elastic element connected to the rotating shaft 52. The elastic element is used to provide pressure to the rotating shaft 52 in the direction of rotation toward the seedling 101.

[0079] In this embodiment, there are multiple pressure strips 51, which are arranged side by side and spaced apart.

[0080] Please refer to Figure 5In other embodiments, the seedling-releasing module 30 includes an arc-shaped module 102 and a straight module 103, which are connected. The seedling-receiving module 20 is positioned above the arc-shaped module 102. The arc-shaped module 102 is used to keep the seedlings 101 in a horizontal position before they are separated by the seedling-receiving module 20. This allows the seedling-receiving module 20 to separate the seedlings more effectively and reduces damage to the seedlings during separation. Simultaneously, the arc shape of the arc-shaped module 102 lowers the vertical height of the seedling-releasing tray 31, facilitating replacement.

[0081] In summary, this invention provides a seedling throwing mechanism 100 and a seedling throwing system 1000. The seedling throwing mechanism 100 includes an installation module 10, a seedling releasing module 30, and a seedling picking module 20. The installation module 10 is mounted on a drone 200. The seedling releasing module 30 is mounted on the installation module 10 and is used to transport the seedling mat 101. The seedling picking module 20 is mounted on the installation module 10 and is located above the seedling releasing module 30. The seedling picking module 20 is used to separate the seedling mat 101 from the seedling mat 30 and throw it out. Because the seedling picking module 20 generates significant vibration during the separation of the seedling mat 101 and seedling throwing operation, the distance between the seedling picking module 20 and the drone 200 is relatively large in the scheme where the seedling picking module 20 is located below the seedling releasing module 30. The vibration is amplified to the drone 200's fuselage through the long lever arm, affecting the drone 200's flight stability. In this solution, the seedling-collecting module 20 is positioned above the seedling-releasing module 30, making the seedling-collecting module 20 very close to the drone 200. This shortens the distance between the seedling-collecting module 20 and the drone 200, and consequently shortens the lever arm between them. This reduces the vibration experienced by the drone 200 when the seedling-collecting module 20 separates the seedlings 101 and releases the seedlings, allowing the drone 200 to remain stable during flight and improving its flight stability and reliability.

[0082] The rice seedling throwing system 1000 includes a drone 200 and at least one seedling throwing mechanism 100, with a mounting module 10 mounted on the lower part of the drone 200. In conventional technology, the seedling-collecting module generates significant vibration during the separation of the seedbed 101 and seedling throwing operation. However, in this seedling throwing mechanism 100, because the seedling-collecting module 20 is positioned above the seedling-releasing module 30, the seedling-collecting module 20 is very close to the drone 200. This shortens the distance between the seedling-collecting module 20 and the drone 200, and consequently shortens the lever arm between them. This reduces the vibration experienced by the drone 200 during the separation of the seedbed 101 and seedling throwing operation, ensuring the drone 200 remains stable during flight and improving its flight stability and reliability.

[0083] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
