[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] The application of drones in the agricultural field is already quite extensive. Drones can be equipped with various operating systems and can perform agricultural spraying and sowing operations. At present, when drones are used for seedling throwing operations, the seedling throwing structure is generally set at the bottom of the drone. The seedling throwing structure follows the drone to fly above the farmland and performs seedling throwing operations during the flight.

[0042] The seedling throwing mechanism in the related art has the problem that the vibration generated by the seedling throwing operation will affect the flight of the drone, resulting in poor flight stability of the seedling throwing mechanism.

[0043] Please refer to Figure 1-Figure 5 The present embodiment provides a 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 is used to separate the blanket seedlings 101, and the separated seedlings are thrown out by centrifugal force or ejected by an ejection member to achieve the seedling throwing operation, and at the same time, the flying seedling throwing operation is achieved in conjunction with the flight of the drone 200. The seedling throwing system 1000 can effectively improve the above-mentioned technical problems, reduce the impact of the vibration generated by the seedling throwing operation 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 components and sowing components required for agriculture, and can achieve spray irrigation, sowing, etc. Of course, the carrier can also carry a camera, a game device, etc. At the same time, the carrier is not limited to the drone 200, for example, the carrier can also be a robot, an unmanned vehicle, an unmanned ship, etc.

[0045] In this embodiment, the drone 200 is a rotor drone, specifically a quad-rotor drone, and of course, it can also be a single-rotor drone, a dual-rotor drone, a six-rotor drone, an eight-rotor drone, etc. The drone 200 can automatically run according to a preset path, flight speed, attitude, etc., or be manually controlled by an operator.

[0046] Please refer to Figure 1-Figure 5 The seedling throwing mechanism 100 includes an installation module 10, a seedling placing module 30 and a seedling taking module 20. The installation module 10 is used to be set on the drone 200. The seedling placing module 30 is set on the installation module 10. The seedling placing module 30 is used to transport the seedling blanket 101. The seedling taking module 20 is set on the installation module 10, and the seedling taking module 20 is located above the seedling placing module 30. The seedling taking module 20 is used to separate the seedlings from the seedling blanket 101 on the seedling placing module 30 and then throw them out by centrifugal force or by ejection of an ejection member.

[0047] Specifically, compared with the placement of the seedling picking module below the seedling placing module, when the drone is equipped with the seedling throwing mechanism for flight operation, the seedling picking module will rotate at high speed when separating the blanket seedlings on the seedling placing module, resulting in greater vibration, thereby affecting the flight stability of the drone. The seedling picking module 20 of the seedling throwing mechanism 100 in this embodiment is located above the seedling placing module 30, so that the seedling picking module 20 is closer to the drone 200, and the center of gravity of the seedling picking module 20 is closer to the center of gravity of the drone 200, so that the drone 200 can fly more stably with the seedling throwing mechanism 100.

[0048] It should be noted here that the seedling taking module 20 is located above the seedling placing module 30, and the "above" is only to indicate that the position of the seedling taking module 20 is 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 connecting member 12. The tripod 11 is arranged at the lower part of the drone 200. The connecting member 12 simultaneously connects the drone 200 and the tripod 11. The seedling placing module 30 and the seedling taking module 20 are both arranged on the tripod 11.

[0050] In this embodiment, the seedling removal module 20 includes a driving source 23 and a cutter head 22. The driving source 23 is installed on the tripod 11, and the driving source 23 and the cutter head 22 are connected. The driving source 23 is used to drive the cutter head 22 to cut the blanket seedlings 101 on the seedling placement module 30, separate the seedlings by cutting, and then throw them out by centrifugal force. Alternatively, an ejection member 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 the seedlings and hold the seedlings to continue rotating. When the cutter head 22 rotates to a specific position, the ejection member of the cutter head 22 is released and ejected, and the seedlings stuck on the seedling needles are ejected to achieve seedling throwing.

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

[0052] It should be noted that the cutter head 22 can be directly mounted on the output shaft of the driving source 23, and the driving source 23 directly drives the cutter head 22 to rotate, or the cutter head 22 can be rotatably mounted on the mounting module 10, and the driving source 23 is mounted on the mounting module 10, and connected to the cutter head 22 through a transmission mechanism, such as (gear box, connecting rod mechanism, sprocket mechanism, pulley mechanism) to provide driving force. Of course, the driving source 23 can also be other than a motor, for example, a pneumatic motor, a gasoline engine, etc.

[0053] In this embodiment, the seedling removal module 20 further includes a transmission box 21, a driving source 23 connected to the transmission box 21, and used to drive the transmission box 21 to rotate, and at least one cutter head 22 is arranged on each transmission box 21. The transmission box 21 can give the cutter head 22 a specific motion trajectory. Generally, a plurality of mutually meshing gears can be arranged inside the transmission. The driving source 23 meshes with a certain gear in the transmission box 21, and the cutter head 22 meshes with another certain gear. The transmission box 21 can make the motion trajectory of the cutter head 22 and the posture of the cutter head 22 during the motion process meet the requirements.

[0054] In order to improve the efficiency of removing seedlings, the rotation speed of the cutter head 22 is usually increased. Of course, too fast a speed may cause other problems such as heat dissipation and unstable cutting. In order 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 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 may be distributed, 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 may be 180 degrees, three cutter heads 22 may be spaced 120 degrees apart, and four cutter heads 22 may be spaced 90 degrees apart. In other words, the cutter heads 22 may be arranged in a uniform distribution. Of course, it is not excluded that the cutter heads 22 may be arranged in an uneven distribution in a certain scenario.

[0056] By designing a larger number of cutter heads 22 on the transmission box 21, the efficiency of removing seedlings can be improved at the same rotation speed. In addition, in terms of installation, the transmission box 21 can be directly installed on the output shaft of the driving source 23, or the transmission box 21 can be rotatably installed on the mounting module 10, the driving source 23 is installed on the mounting module 10, and is connected to the transmission box 21 through a transmission mechanism, such as (gear box, connecting rod mechanism, sprocket mechanism, pulley mechanism) to provide driving force.

[0057] It should be noted that the seedling placing module 30 includes a seedling placing tray 31 and a seedling blocking plate 32, the seedling blocking plate 32 is connected to the mounting module 10, the seedling blocking plate 32 is located above the seedling placing tray 31, the top of the seedling placing tray 31 is located in the seedling blocking plate 32, and the seedling placing tray 31 is slidably arranged on the mounting module 10, the seedling placing tray 31 can move laterally relative to the seedling blocking plate 32, the seedling blocking plate 32 is provided with an opening, and the seedling taking module 20 is used to separate the seedling blanket 101 on the seedling placing tray 31 through the opening, and centrifugally eject the separated seedlings or eject them by ejection of an ejection member.

[0058] The seedling blocking plate 32 is arranged above the seedling placing tray 31 , so as to shield the blanket seedlings 101 on the seedling placing tray 31 and prevent the excessive blanket seedlings 101 from protruding or falling from above the seedling placing tray 31 .

[0059] Specifically, the positions of the openings of the seedling placing module 30 and the seedling retaining plate 32 remain unchanged relative to the mounting module 10, and the seedling placing tray 31 can reciprocate in the left and right directions. In this way, the seedling placing module 30 only cuts the blanket seedlings 101 exposed in the opening, so that the blanket seedlings 101 can be cut and thrown row by row and bunch by bunch. Of course, in other embodiments, the position of the seedling placing tray 31 relative to the mounting module 10 may remain unchanged, while the seedling retaining plate 32 and the seedling placing module 30 can move laterally in the left and right directions.

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

[0061] Please refer to Figure 3 and Figure 4There are multiple seedling placing modules 30, and the multiple seedling placing modules 30 are respectively arranged on both sides of the mounting module 10. The number of seedling retrieval modules 20 corresponds to the number of seedling placing modules 30, and the multiple seedling retrieval modules 20 are all arranged on the top of the mounting module 10.

[0062] Specifically, in order to reduce the influence of the wind field of the drone 200 on the seedling picking module 20 during the seedling throwing process, multiple seedling picking modules 20 are arranged at the center of the mounting module 10. As a result, the positions of the rotors of the seedling picking module 20 and the drone 200 are staggered, reducing the influence of the wind field generated by the rotors on the seedling picking module 20 during the seedling throwing process, thereby improving the accuracy of the seedling throwing process. In other embodiments, multiple seedling picking modules 20 can also be arranged at the edge positions of the mounting module 10.

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

[0064] In other embodiments, the number of seedling placing modules 30 may be increased or decreased, which is not specifically limited herein.

[0065] More preferably, the seedling placing module 30 includes at least two seedling placing trays 31 , and at least two seedling placing trays 31 are arranged side by side. The seedling retaining plate 32 has a plurality of openings, and the number of the openings corresponds to the number of the seedling placing trays 31 . A seedling taking module 20 is provided above each seedling placing tray 31 .

[0066] In this embodiment, the seedling placing module 30 includes three seedling placing trays 31, and the three seedling placing trays 31 are arranged side by side. This allows the drone 200 to complete multiple rows of seedling placing operations in one flight, thereby improving the efficiency of seedling placing. In other embodiments, the number of seedling placing trays 31 of the seedling placing module 30 can be increased or decreased, which is not specifically limited here.

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

[0068] More specifically, the seedling throwing mechanism 100 further includes a seedling sending module 40, which is disposed on the mounting module 10 and is used to transport the seedling blanket 101 on the seedling placing module 30 upward. Specifically, the seedling sending module 40 includes a transmission member and a transmission motor, the transmission motor is connected to the mounting module 10, the transmission member is connected to the transmission motor, and the transmission member is used to transport the seedling blanket 101 on the seedling placing module 30 upward.

[0069] It can be understood that the transmission member is a transmission belt or a transmission wheel.

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

[0071] It should be noted that a plurality of seedling delivery modules 40 can be arranged on the seedling placing module 30, and the arrangement heights of the plurality of seedling delivery modules 40 can be different, so as to more reliably transport the seedlings upward.

[0072] It can be understood that a connecting groove runs through the seedling tray 31, and the transmission member is connected to the seedling blanket 101 on the seedling tray 31 through the connecting groove, thereby realizing the function of conveying the seedling blanket 101 upward.

[0073] Furthermore, the seedling placing module 30 is tilted relative to the mounting module 10 , thereby reducing the space occupied by the seedling placing module 30 in horizontal width.

[0074] In this embodiment, the seedling placing module 30 further includes a transverse driving source 60, which is connected to the seedling placing disc 31, and the transverse driving source 60 is used to drive the seedling placing module 30 to perform reciprocating motion in the transverse direction.

[0075] Specifically, the transverse driving source 60 includes a transverse motor, a transverse gear and a transverse rack. The transverse motor is installed on the installation module 10. The transverse motor and the transverse gear are connected. The transverse rack is arranged on the back of the seedling tray 31, and the transverse rack and the transverse gear are meshed. The transverse gear rotates under the drive of the transverse motor, thereby driving the transverse rack to perform linear reciprocating motion, and then driving the seedling tray 31 to perform linear reciprocating motion.

[0076] In addition, a seedling pressing device 50 is provided on the seedling placing module 30 . The seedling pressing device 50 is arranged on the seedling placing module 30 , and is used to limit the position of the blanket seedlings 101 in the seedling placing module 30 .

[0077] Specifically, the seedling pressing device 50 includes a pressure bar 51 and a rotating shaft 52. The pressure bar 51 is arranged along the conveying direction of the blanket seedlings 101. The pressure bar 51 is connected to the rotating shaft 52. The rotating shaft 52 is rotatably arranged on the seedling placing module 30. The pressure bar 51 is used to press down the blanket seedlings 101 to limit the position through the force of the rotating shaft 52.

[0078] In addition, the seedling pressing device 50 further includes an elastic member, which is connected to the rotating shaft 52 , and the elastic member is used to provide pressure to the rotating shaft 52 to rotate toward the blanket seedlings 101 .

[0079] In this embodiment, there are multiple pressure strips 51 , and the multiple pressure strips 51 are arranged side by side and at intervals.

[0080] Please refer to Figure 5In other embodiments, the seedling placing module 30 includes an arc module 102 and a straight module 103, the arc module 102 and the straight module 103 are connected, and the seedling taking module 20 is arranged above the arc module 102, and the arc module 102 is used to make the blanket seedlings 101 tend to a horizontal state before being separated by the seedling taking module 20. Thus, the seedling taking module 20 can better separate the seedlings and reduce the damage to the seedlings when separating the seedlings; at the same time, because the arc module 102 has a curvature, the vertical height of the seedling placing tray 31 becomes lower, so that it is convenient to replace.

[0081] In summary, the embodiment of the present invention provides a seedling throwing mechanism 100 and a seedling throwing system 1000, wherein the seedling throwing mechanism 100 comprises a mounting module 10, a seedling placing module 30 and a seedling taking module 20, wherein the mounting module 10 is used to be arranged on the drone 200, the seedling placing module 30 is arranged on the mounting module 10, the seedling placing module 30 is used to transport the blanket seedlings 101, the seedling taking module 20 is arranged on the mounting module 10, and the seedling taking module 20 is located above the seedling placing module 30, and the seedling taking module 20 is used to separate the seedlings from the blanket seedlings 101 on the seedling placing module 30 and then throw them out. Since the seedling taking module 20 will generate a large vibration when separating the blanket seedlings 101 and performing the seedling throwing operation, for the solution in which the seedling taking module 20 is arranged below the seedling placing module 30, the distance between the seedling taking module 20 and the drone 200 is relatively far, and the vibration is amplified to the fuselage of the drone 200 through a relatively long force arm, which affects the flight stability of the drone 200. In the present solution, since the seedling taking module 20 is arranged above the seedling placing module 30, the seedling taking module 20 is very close to the drone 200, the distance between the seedling taking module 20 and the drone 200 is shortened, and the force arm between the seedling taking module 20 and the drone 200 is also shortened accordingly, thereby reducing the vibration of the drone 200 when the seedling taking module 20 separates the blanket seedlings 101 and places the seedlings, so that the fuselage of the drone 200 remains stable during the flight, thereby improving the flight stability and reliability of the drone 200.

[0082] The seedling throwing system 1000 includes a drone 200 and at least one seedling throwing mechanism 100, and the mounting module 10 is mounted on the lower part of the drone 200. The seedling picking module in the conventional technology will generate a large vibration when separating the blanket seedlings 101 and throwing the seedlings. When the seedling throwing mechanism 100 is in use, since the seedling picking module 20 is arranged above the seedling placing module 30, the seedling picking module 20 is very close to the drone 200, the distance between the seedling picking module 20 and the drone 200 is shortened, and the force arm between the seedling picking module 20 and the drone 200 is also shortened, thereby reducing the vibration of the drone 200 when the seedling picking module 20 separates the blanket seedlings 101 and throws the seedlings, so that the fuselage of the drone 200 remains stable during the flight, and the flight stability and reliability of the drone 200 are improved.

[0083] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
