Description

Technical Field

[0002] Traditional transplanting or throwing techniques generally use manual transplanting and manual throwing, which are both inefficient methods, so the current mainstream and efficient method is transplanting. However, while transplanting machines bring mechanization and large-scale operations, they also bring problems. For example, it is difficult to transport seedlings from the roadside to the field. It takes a lot of manpower to transport the seedlings from the roadside to the field; and they also need to be lined up in a row at the field to meet the dynamic seedling needs of the transplanter during operation. Not only that, the transplanter is a ground machine with a huge weight, and it has to enter complex terrain to operate. It has high requirements for ground road conditions. Some terraces, mountain fields, and small plots of fields cannot be transplanted with transplanters, and transplanters are often easily stuck in the mud and cannot get out. Summary of the invention

[0078] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0079] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0081] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0082] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0083] 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.

[0084] As described in the background technology, traditional transplanting or throwing techniques generally use manual transplanting and manual throwing, which are both slow working methods, so the current mainstream and efficient method is the transplanter operation. However, while the transplanter brings mechanization and large-scale operations, it also brings problems. For example, the seedlings are difficult to transport from the roadside to the field, and a large amount of manpower is required to transport the seedlings from the roadside to the field; and they also need to be lined up in a row at the field to meet the dynamic seedling needs of the transplanter during the operation. Not only that, the transplanter is a ground machine with a huge weight, and it enters complex terrain to operate. It has high requirements for ground road conditions. Some terraces, mountain fields, and small plots of fields cannot be transplanted with transplanters, and transplanters are often easily stuck in the mud and cannot get out.

[0085] In order to solve the above technical problems, the embodiments of the present invention provide a drone and a seedling transplanting device, which can solve the problem of transporting seedlings to the field and will not be restricted by the ground terrain like a rice transplanter. It can also solve the efficiency problem of manual seedling transplanting and realize a mechanized, automated and large-scale seedling transplanting operation method.

[0086] See also Figure 1 and Figure 2 The embodiment of the present invention provides a drone seedling throwing system 10, which includes a seedling separation device 100 and a drone 200. The seedling separation device 100 is placed on the ground and is used to separate multiple seedlings from a seedling block. The drone 200 includes a body 210, a load container 220 and a seedling throwing mechanism 230. The load container 220 is disposed on the body 210, and is used to carry multiple seedlings separated from the seedling separation device 100. The seedling throwing mechanism 230 is disposed on the load container 220 or the body 210, and is used to throw out multiple seedlings in the load container 220 when the drone 200 flies above the target working area 11.

[0087] During operation, a plurality of seedlings are separated from the seedling block by the seedling separation device 100 placed on the ground, and the plurality of seedlings are loaded into the load container 220. The drone 200 carries the load container 220 and flies above the target operation area 11. The seedling throwing mechanism 230 throws out the plurality of seedlings in the load container 220, so that the plurality of seedlings are thrown into the target operation area 11. In this way, the operation mode of picking seedlings on the ground and throwing seedlings in the air is realized. The seedling separation device 100 is used to separate and pick seedlings, which solves the problem of transporting seedlings to the field, and is not restricted by the ground terrain. In addition, the use of the drone 200 for throwing seedlings can also solve the efficiency problem of manual throwing seedlings.

[0088] In this embodiment, the drone 200 may be a rotor drone, for example, a quad-rotor drone. Of course, the drone 200 may also be a single-rotor drone, a dual-rotor drone, a six-rotor drone, an eight-rotor drone, etc. The drone 200 may automatically operate according to a preset path, flight speed, attitude, etc., or may be manually controlled by an operator.

[0089] The load container 220 can be detachably connected to the body 210. The detachable connection method of the load container 220 and the body 210 is not specifically limited, and can be a snap connection, a bolt connection, etc. When the load container 220 is removed from the body 210, the load container 220 can be placed alone in the rice-separating device 100 to carry a plurality of rice seedlings separated from the rice-separating device 100. Of course, in some embodiments, the load container 220 may not be detachably connected to the body 210, and the drone 200 is placed as a whole in the rice-separating device 100. Under the condition of meeting the structural avoidance requirements, it is sufficient as long as the plurality of rice seedlings separated from the rice-separating device 100 can be sent to the load container 220. In addition, a rice seedling entrance is provided at the top of the load container 220, and the load container 220 is a barrel-shaped structure with a large upper portion and a small lower portion, so as to carry a plurality of rice seedlings separated from the rice-separating device 100.

[0090] The seedling block can be a blanket seedling or a plug tray seedling, or can also be other types of seedling blocks. If the seedling block is a blanket seedling, the seedling separation device can use a seedling needle cutting method to separate; if the seedling block is a plug tray seedling, a push pin can be used to separate and remove a single bunch of seedlings. In the embodiment of the present invention, for the convenience of introduction, the seedling block is taken as an example for detailed description.

[0091] See also Figure 3-Figure 5 The seedling separation device 100 includes a support 110, a conveying device 120 and a separation device 130. The support 110 is placed on the ground. The conveying device 120 is provided with a seedling separation opening 121. The conveying device 120 is connected to the support 110 and is used to carry the seedling block and convey the seedling block to the seedling separation opening 121. The separation device 130 is connected to the support 110 and is located above the load container 220. It is used to separate a plurality of seedlings from the seedling block located at the seedling separation opening 121 so that the plurality of seedlings fall into the load container 220.

[0092] It should be noted that the "ground" referred to here does not have to be the head of the field, and a place that is easily accessible can be selected. It is not necessary to transport the seedling separation device 100 to the head of the field. In this way, the seedling separation device 100 is not restricted by the terrain of the field, and the drone 200 can be used to carry the load container 220 to transport and throw the seedlings. In addition, it should be noted that in an optional embodiment, the seedling separation device 100 can also be a rice transplanter. After the rice transplanting mechanism of the rice transplanter is raised, the rice transplanting needles can be used to separate the rice seedlings. The load container 220 can be placed below the raised rice transplanting mechanism to carry multiple rice seedlings separated from the rice transplanting needles.

[0093] When separating and taking out seedlings, the conveying device 120 continuously conveys the seedling block to the seedling separation opening 121, and the separating device 130 separates a plurality of seedlings from the seedling block at the seedling separation opening 121. Since the loading container 220 is located below the seedling separation opening 121, after the separating device 130 separates a plurality of seedlings, the seedlings fall into the loading container 220 under the action of gravity. In this way, the automatic separation of the seedling block and the automatic loading of the seedlings are realized.

[0094] In this embodiment, in order to make the structure of the rice seedling separation device 100 more compact and to make the rice seedling loading more convenient, a receiving cavity 111 is formed in the bracket 110, and the load container 220 can be accommodated in the receiving cavity 111 when it is detached from the body 210. In other words, after the load container 220 is detached from the body 210, it can be placed in the receiving cavity 111 alone. At this time, the load container 220 is located below the rice seedling separation opening 121 to carry the rice seedlings falling from the rice seedling separation opening 121. After the rice seedlings are loaded, the load container 220 only needs to be taken out of the receiving cavity 111 and assembled to the body 210, and the subsequent rice seedling throwing operation of the drone 200 can be carried out.

[0095] In some optional embodiments of the present invention, the conveying device 120 may include a seedling tray 122. In addition, the seedling separation device 100 further includes a support frame 140. The support frame 140 is disposed on the bracket 110, the seedling tray 122 is obliquely disposed on the support frame 140, and a seedling separation opening 121 is disposed at the bottom end of the seedling tray 122.

[0096] It should be noted that the seedling tray 122 is used to carry the seedling blocks. Optionally, the seedling tray 122 includes a bottom plate 1221 and a baffle 1222 arranged around the bottom plate 1221, so that an opening for the seedling blocks to be placed is formed on the side of the baffle 1222 away from the bottom plate 1221, and the seedling opening 121 is opened on the baffle 1222 at one end in the length direction of the seedling tray 122. When placing the seedling blocks, manual or automatic methods can be used to spread the seedling blocks on the bottom plate 1221. Since the entire seedling tray 122 is tilted, the seedling tray 122 transports the seedling blocks through the gravity of the seedling blocks themselves. It should be understood that when the separation device 130 separates the seedling blocks at the seedling opening 121, it has a certain downward force on the seedling blocks, which can pull the seedling blocks downward. In addition, the seedling blocks can move downward under the action of gravity to continuously replenish the seedling opening 121.

[0097] In order to improve the efficiency of ground seedling picking and increase the seedling release capacity of the equipment, if the conveying device 120 and the separation device 130 are considered to be a group of seedling picking components, multiple groups of seedling picking components can be set up, and the multiple groups of seedling picking components can be arranged side by side. The multiple groups of seedling picking components can simultaneously perform seedling separation on a load container 220. That is to say, if the size permits, multiple groups of seedling picking components can be set above a load container 220 at the same time. Taking three groups as an example in the figure, a three-fold increase in the efficiency of ground seedling picking can be achieved. By analogy, as long as the site permits, the number of seedling picking components can be further increased, and the efficiency can be increased by at least three times to meet the number of seedlings released by the drone 200.

[0098] See also Figure 6 Furthermore, a plurality of load containers 220 may be placed in a support 110 at the same time, and each load container 220 corresponds to a plurality of sets of seedling removal components, so that the seedlings of a plurality of drones 200 can be supplied, which can significantly improve the efficiency of seedling removal and the amount of seedling release. In the figure, three load containers 220 are placed as an example, and each load container 220 corresponds to three sets of seedling removal components, so that a total of nine sets of seedling removal components can provide seedlings to three drones 200.

[0099] Please continue reading Figure 4In addition, the support frame 140 may include a first support frame 141 and a second support frame 142. The first support frame 141 and the second support frame 142 are both connected to the bracket 110, and a support plate 1411 is provided on the first support frame 141, and a connecting port 1412 is provided on the support plate 1411. One end of the conveying device 120 is placed on the support plate 1411, and the other end is supported on the second support frame 142, and the seedling separation port 121 is connected with the connecting port 1412. In this way, the conveying device 120 can be better supported. Further, in order to better support the seedling tray 122 and ensure the seedling removal effect, in an optional embodiment in which the conveying device 120 adopts the seedling tray 122, the bottom end of the seedling tray 122 is placed on the support plate 1411, and the positions of the seedling separation port 121 and the connecting port 1412 correspond and are connected, so that the separation device 130 separates a plurality of seedlings from the seedling block.

[0100] See also Figure 7 In order to improve the efficiency of seedling block transportation, in some embodiments, the seedling separation device 100 may further include a seedling delivery roller 150. The seedling delivery roller 150 is rotatably connected to the bracket 110 and is disposed near the seedling separation opening 121, and is used to drive the seedling block to move toward the seedling separation opening 121 when rotating. The rotation of the seedling delivery roller 150 generates a force on the seedling block, driving the seedling block to continuously move toward the seedling separation opening 121 to supplement the seedling block at the seedling separation opening 121.

[0101] See also Figure 8 and Fig. 9 Some other optional embodiments of the present invention provide another seedling separation device 100, which is different from the above-mentioned embodiment in which the seedling tray 122 is inclined in that the structure of the seedling tray 122 is different. For the parts not introduced, please refer to the introduction in the above-mentioned embodiment. In the seedling separation device 100 provided by these optional embodiments, the seedling tray 122 can be set horizontally as a whole or at least partially horizontally, which can facilitate the portable seedling placement of the seedling separation device 100 and facilitate the placement and removal of seedlings. Optionally, the seedling tray 122 may include a horizontal section 1223 set horizontally and an inclined section 1224 set obliquely. Among them, the upper end of the inclined section 1224 is connected to one end of the horizontal section 1223, and the lower end is provided with a seedling separation port 121, and the horizontal section 1223 and the inclined section 1224 are both arranged on the support frame 140. Further optionally, the seedling separation port 121 is arranged on the baffle 1222 at the lower end of the inclined section 1224. The length of the inclined section 1224 is less than the length of the horizontal section 1223. The horizontal section 1223 is provided to facilitate placement of the seedling block, and the inclined section 1224 is provided to facilitate movement of the seedling block toward the seedling separation opening 121 under the action of gravity. The use of such a seedling tray 122 can help reduce the overall height of the seedling separation device 100, making it easier to place and remove the seedlings.

[0102] In the embodiment where the seedling tray 122 is provided with a horizontal section 1223 and an inclined section 1224, a seedling delivery roller 150 (see Figure 7 ), the seedling delivery roller 150 is rotatably connected to the bracket 110 and is arranged near the seedling separation opening 121, so that the seedling delivery roller 150 is arranged closer to the inclined section 1224, so as to drive the seedling block to continuously move toward the seedling separation opening 121.

In this way, the support function of the horizontal section 1223 and the inclined section 1224 can be well ensured, which is convenient for separating the seedlings.

[0104] See also Fig.10 In order to improve the efficiency of picking up seedlings on the ground and increase the amount of seedlings released by the equipment, multiple seedling separation devices 100 can be provided, and multiple seedling separation devices 100 are arranged side by side. Each seedling separation device 100 corresponds to a load container 220 for loading seedlings.

[0105] See also Fig.11 and Fig.12 Some other optional embodiments of the present invention provide another seedling separation device 100, which is different from the above-mentioned embodiment using a seedling tray 122 in that the structure of the conveying device 120 is different. For parts not described herein, reference may be made to the description in the above-mentioned embodiment. In the seedling separation device 100 provided in these optional embodiments, the conveying device 120 adopts a conveyor belt transmission method.

[0106] Optionally, the conveying device 120 may include a first conveyor belt 1231, at least two first rollers 1232, a first mounting frame 1233 and a guide plate 1234. The first conveyor belt 1231 is horizontally arranged on the bracket 110. Optionally, the first conveyor belt 1231 is wound around at least two first rollers 1232, each first roller 1232 is rotatably connected to the first mounting frame 1233, and the first mounting frame 1233 is connected to the bracket 110, so that both ends of the first conveyor belt 1231 can be supported on the first mounting frame 1233.

During transportation, the seedling blocks can be laid on the first conveyor belt 1231 and the guide plate 1234. The first conveyor belt 1231 can horizontally convey the seedling blocks, and the seedling blocks move downward on the inclined guide plate 1234. In this way, the separation device 130 separates the seedling blocks, and the first conveyor belt 1231 continuously conveys the seedling blocks, so that the seedling blocks are continuously replenished at the seedling separation port 121. The first conveyor belt 1231 can be used for transportation to improve the efficiency of seedling block transportation, thereby improving the efficiency of seedling separation.

[0107] In addition, the rice seedling separation device 100 may further include a first support frame 141, and the first support frame 141 is connected to the bracket 110. A support plate 1411 is provided on the first support frame 141, and the support plate 1411 is provided with a communication port 1412. The lower end of the guide plate 1234 is placed on the support plate 1411, and the rice seedling separation port 121 is connected to the communication port 1412, so that the separation device 130 separates a plurality of rice seedlings from the rice seedling block.

[0108] In addition, the conveying device 120 may further include a panel 124. The panel 124 is arranged around the first conveyor belt 1231 and the guide plate 1234, and can play a certain role in protecting, guiding and preventing the seedling block from deflecting. It should be noted that the seedling separation port 121 can be optionally arranged on the panel 124 at the lower end of the guide plate 1234.

[0109] See also Fig.13 and Fig.14 In order to improve the efficiency of picking up seedlings on the ground and increase the amount of seedlings released by the equipment, the first conveyor belt 1231 can be lengthened. The length L2 of the first conveyor belt 1231 can be n times the length L1 of the seedling tray 122. The seedling tray 122 referred to here is the inclined seedling tray 122 in the above embodiment. That is, L2 = nL1, where n>1, and as an example, n can be 2. In this way, the efficiency of picking up seedlings on the ground can be significantly improved.

[0110] Please continue reading Figure 4Based on any of the above embodiments, the structure of the separation device 130 is described in detail below. The seedling block can be optionally a blanket seedling. In order to facilitate the separation of the blanket seedling, in an optional embodiment of the present invention, the separation device 130 may include a seedling separation motor 131, a rotating arm 132, a seedling removal blade head 133 and a connecting rod 134. Among them, the seedling separation motor 131 is connected to the bracket 110 through a connecting rod 134, the seedling separation motor 131 is transmission-connected to the rotating arm 132, and the rotating arm 132 is connected to the seedling removal blade head 133. The seedling removal blade head 133 can rotate under the drive of the rotating arm 132 and pass through the seedling separation mouth 121, thereby separating a plurality of seedlings from the seedling block located at the seedling separation mouth 121, wherein the seedling block is a blanket seedling. As an example, the seedling separation motor 131 can be connected to the first support frame 141 through a connecting rod 134, and the first support frame 141 is connected to the bracket 110, so that the position of the arrangement is closer to the seedling separation mouth 121.

[0111] When separating the blanket seedlings, the seedling separation motor 131 drives the rotating arm 132, and the rotating arm 132 rotates to drive the seedling removal blade head 133 to rotate through the seedling separation opening 121, thereby separating multiple independent seedlings from the blanket seedlings located at the seedling separation opening 121. The separated multiple seedlings fall into the load container 220 under the action of gravity, and the seedlings are separated and loaded. By providing the seedling separation motor 131, the rotating arm 132 and the seedling removal blade head 133, the seedling separation can be made more automated and the efficiency of the seedling separation can be improved.

[0112] See also Fig.15In addition, in order to enable the load container 220 to be loaded on the machine body 210 more quickly after the rice seedlings are loaded, on the basis of any of the above embodiments, an optional embodiment of the present invention further provides a rice seedling separation device 100, and the description of the above embodiments may be referred to for the parts not described. As an example, the rice seedling separation device 100 may also include a conveyor 125 and a carrier 126. The conveyor 125 is partially arranged in the accommodating cavity 111 and partially extends out of the accommodating cavity 111, and the conveyor 125 is used to carry the load container 220. The carrier 126 is arranged outside the accommodating cavity 111 and is used to carry the machine body 210. It should be understood that the load container 220 is detachably connected to the machine body 210, and the load container 220 can be placed on the conveyor 125 in a state of being detached from the machine body 210. In addition, a card slot 221 is arranged on the load container 220, a card hook 211 is arranged on the machine body 210, and the machine body 210 is placed on the carrier 126. The conveying device 125 is used to convey the load container 220 out of the accommodating cavity 111, and convey the load container 220 to the carrier 126, so that the load container 220 pushes the hook 211 to deform, until the hook 211 is locked in the slot 221 after restoring the deformation. The conveying device 125 can be a conveyor belt or other device. There are at least two hooks 211, which are arranged at intervals at both ends of the body 210, and correspondingly, there are at least two slots 221, which are arranged on the outer walls of the load container 220 on both sides opposite to each other.

[0113] After the load container 220 is loaded with the seedlings, the conveying device 125 can be controlled to convey the load container 220, and the load container 220 can be conveyed out of the accommodating cavity 111 of the support 110 and conveyed to the carrier 126. The load container 220 can push the hook 211 to deform during the movement. In an optional embodiment, the load container 220 moves between the two hooks 211 and pushes the hook 211 to deform, and then continues to move until the hook 211 enters the slot 221, and the hook 211 recovers its deformation and is held in the slot 221, thereby achieving the clamping and fixing of the load container 220 and the machine body 210. In this way, the load container 220 can be installed on the machine body 210 more automatically and quickly.

[0114] In addition, based on any of the above embodiments, the structure of the seedling throwing mechanism 230 is specifically described below. It should be noted that the seedling throwing mechanism 230 can be set in the load container 220, or can be set on the machine body 210, as long as it can achieve the throwing of the seedlings in the load container 220. In order to facilitate the throwing of seedlings, the embodiment of the present invention is described by taking the seedling throwing mechanism 230 being set in the load container 220 as an example.

[0115] See also Fig.16 and Fig.17In some optional embodiments of the drone 200, the first seedling throwing mechanism 230 can be selected. As an example, the seedling throwing mechanism 230 includes at least two seedling throwing rollers 231 arranged in parallel. A seedling throwing port 222 is provided at the bottom of the load container 220, and the gap between at least two seedling throwing rollers 231 is arranged corresponding to the seedling throwing port 222. Optionally, at least two seedling throwing rollers 231 are arranged at the bottom position of the load container 220. The seedling throwing roller 231 can be connected to a driving device to drive the seedling throwing roller 231 to rotate through the driving device. By controlling the rotation of at least two seedling throwing rollers 231, the seedling throwing roller 231 can be used to assist the seedling throwing downward, so that the seedling is thrown out of the seedling throwing port 222, thereby improving the efficiency of seedling throwing.

[0116] See also Fig.18 and Fig.19 In some optional embodiments of the drone 200, the second seedling throwing mechanism 230 may be selected. As an example, the seedling throwing mechanism 230 includes a fan 2321 and an air supply duct 2322. The fan 2321 is connected to the outer wall of the load container 220, the fan 2321 is connected to one end of the air supply duct 2322, and the other end of the air supply duct 2322 is connected to the outer wall of the lower part of the load container 220. The bottom of the load container 220 is provided with a seedling throwing port 222.

[0117] By providing the fan 2321 and the air supply duct 2322, the fan 2321 can deliver air to the lower part of the load container 220 through the air supply duct 2322 when it is working. When the seedlings slide to the lower part of the load container 220, they are accelerated to slide outward by the wind force provided by the fan 2321 and are thrown out from the seedling throwing port 222. This airflow assistance method can effectively reduce physical damage to the seedlings and effectively assist in throwing the seedlings down.

[0118] In order to improve the air supply effect and the effect of assisting the seedlings in throwing down, multiple fans 2321 and correspondingly multiple air supply ducts 2322 can be provided. As an example, three fans 2321 can be selected, and three air supply ducts 2322 are correspondingly provided. The three fans 2321 are arranged side by side on the outer side wall of the same side of the load container 220.

[0119] See also Figure 20-Figure 22In some optional embodiments of the drone 200, a third seedling throwing mechanism 230 may be selected. As an example, the seedling throwing mechanism 230 includes a second conveyor belt 2331, at least two second rollers 2332, and a second mounting frame 2333. An opening is provided at the bottom of the load container 220, and the second conveyor belt 2331 is provided below the opening. The second conveyor belt 2331 is wound around at least two second rollers 2332, and each second roller 2332 is correspondingly rotatably connected to a second mounting frame 2333, and the second mounting frame 2333 is connected to the load container 220. The load container 220 is provided with a seedling throwing opening 222 on the side wall corresponding to one end of the second conveyor belt 2331. Optionally, there are two second rollers 2332, and the second conveyor belt 2331 is wound around the two second rollers 2332. In addition, there can be three seedling throwing openings 222 , and the width of the second conveyor belt 2331 can cover the three seedling throwing openings 222 , so that the seedlings conveyed by the second conveyor belt 2331 can be thrown out from the three seedling throwing openings 222 at the same time.

[0120] When the seedlings are thrown, the seedlings slide onto the second conveyor belt 2331 , and the second roller 2332 is controlled to rotate, so that the second conveyor belt 2331 conveys the seedlings to the seedling throwing port 222 , and the seedlings are thrown out from the seedling throwing port 222 .

[0121] See also Fig.18 In addition, based on any of the above embodiments, the drone 200 further includes a door panel 241 and a drive motor 242. A seedling throwing opening 222 is provided at the bottom or side wall of the load container 220. The drive motor 242 is provided at the load container 220 and is transmission-connected to the door panel 241, and is used to open or close the seedling throwing opening 222 under the drive of the drive motor 242. In this way, when seedling throwing is not required, the door panel 241 closes the seedling throwing opening 222. When seedling throwing is required, the drive motor 242 drives the door panel 241 to move linearly or rotate, thereby opening the seedling throwing opening 222.

[0122] As an example, in the above-mentioned embodiment using the second seedling throwing mechanism 230, there are two drive motors 242 and two door panels 241, and the two drive motors 242 are arranged on the outer side walls of the two opposite ends of the load container 220, and each drive motor 242 is rotatably connected to a door panel 241, and the seedling throwing port 222 is arranged at the bottom of the load container 220. Driven by the drive motor 242, the two door panels 241 rotate towards each other, thereby closing the seedling throwing port 222 together; similarly, the two door panels 241 rotate away from each other, thereby opening the seedling throwing port 222. In this way, the double-door opening and closing of the seedling throwing port 222 is realized, which is convenient for quickly throwing the seedlings after opening.

[0123] In summary, when the drone 200 and the rice seedling separation device 100 provided by the embodiment of the present invention are working, the rice seedling separation device 100 placed on the ground separates a plurality of rice seedlings from the rice seedling block, and the plurality of rice seedlings are loaded into the load container 220, and the load container 220 is installed on the body 210. The drone 200 carries the load container 220 and flies to the top of the target operation area 11, and then controls the rice seedling throwing mechanism 230 to throw out the plurality of rice seedlings in the load container 220, so that the plurality of rice seedlings are thrown to the target operation area 11. In this way, the operation mode of picking up seedlings on the ground and throwing seedlings in the air is realized, and the rice seedling separation device 100 is used to separate and pick up seedlings, which solves the problem of transporting seedlings to the field, and is not restricted by the ground terrain. In addition, the use of the drone 200 for throwing seedlings can also solve the efficiency problem of manual throwing seedlings.
