Detailed Implementation

[0038] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The seedling tray is used to hold potted or blanket seedlings for the seedling throwing system to scatter. The cutter head assembly is used to detach the seedlings from the seedling tray for subsequent seedling throwing operations. With only the seedling tray, the number of seedlings that can be loaded into the drone seedling throwing system is limited. Moreover, since one set of seedling trays usually corresponds to one set of cutter head assemblies, adding cutter head assemblies while increasing the seedling trays increases both the equipment cost and the load on the transport equipment, making it unable to meet the load-bearing capacity required to assemble more seedling trays.

[0042] Reference Figure 1-10 As shown, this application provides a drone rice seedling throwing system 100, including a load frame 110, a basic seedling feeding tray 120 disposed in the load frame 110, and a cutter head assembly 140 corresponding to the basic seedling feeding tray 120. The basic seedling feeding tray 120 is movably disposed relative to the load frame 110, and an extension seedling feeding tray 130 can be connected to the end of the basic seedling feeding tray 120. After connection, the extension seedling feeding tray 130 can be moved to the cutter head assembly 140, and the seedlings are cut and thrown through the cutter head assembly 140.

[0043] In this embodiment, the basic seedling tray 120 is a seedling tray assembled with the load frame 110 in a normal state. In the UAV seedling throwing system 100, there is a corresponding cutter head assembly 140. In normal working state, each cutter head assembly 140 cuts the seedlings on the corresponding basic seedling tray 120 to detach them from the basic seedling tray 120. The extended seedling tray 130 is used to be assembled on the basic seedling tray 120. In the UAV seedling throwing system 100, there is no dedicated cutter head assembly 140 for the extended seedling tray 130. During use, after all the seedlings on the basic seedling tray 120 have been cut and thrown, the extended seedling tray 130 is fed to the original position of the basic seedling tray 120. The cutter head assembly 140 at this position continues to work to cut and throw the seedlings on the extended seedling tray 130.

[0044] By setting up an extended seedling delivery tray 130, and having the extended seedling delivery tray 130 and the basic seedling delivery tray 120 share the cutter head assembly 140, the seedling loading capacity of the UAV seedling throwing system 100 is increased without increasing the number of cutter head assemblies 140 used. This improves the working efficiency of the UAV seedling throwing system 100 and avoids the increase in weight and cost of the cutter head assembly 140, resulting in good performance and economic benefits.

[0045] In this application, to install the extended seedling feeding tray 130, it is necessary to fix the extended seedling feeding tray 130 to the basic seedling feeding tray 120 and connect the translation mechanism 150 and the seedling feeding mechanism of the basic seedling feeding tray 120 to the extended seedling feeding tray 130 to achieve the sharing of various drive mechanisms, as shown in the reference. Figure 1 , 2 As shown in Figure 4, in this embodiment of the application, the fixed connection between the extended seedling tray 130 and the basic seedling tray 120 is achieved by providing a hook 1301 and a fixing pin 1302 on the extended seedling tray 130, and a pin hole corresponding to the fixing pin 1302 on the basic seedling tray 120. The extended seedling tray 130 is hung on the basic seedling tray 120 by the hook 1301 and positioned by the fixing pin 1302. In this embodiment, the cooperation between the fixing pin 1302 and the pin hole serves both a positioning function and bears the weight of the extended seedling tray 130, thus achieving a fixed connection between the extended seedling tray 130 and the basic seedling tray 120 in conjunction with the hook 1301.

[0046] It is understood that the connection method between the extended seedling tray 130 and the basic seedling tray 120 is not intended to limit this application. In other embodiments, other solutions that can be conceived by those skilled in the art can be used to achieve the fixed connection between the basic seedling tray 120 and the extended seedling tray 130.

[0047] Meanwhile, this application embodiment also provides a method for implementing the horizontal feeding of the basic seedling tray 120 and the extended seedling tray 130, referring to... Figure 1 As shown, the unmanned aerial vehicle rice-throwing system 100 described in this application embodiment also includes a translation mechanism 150 for driving the basic rice-throwing tray 120 to move horizontally. The extended rice-throwing tray 130 is connected to the basic rice-throwing tray 120 and shares the translation mechanism 150 with the basic rice-throwing tray 120.

[0048] The horizontal moving mechanism in this application has two main functions. First, it moves the seedling feeding trays column by column according to the width of a single row of seedlings so that a certain row of seedlings corresponds to the cutter head assembly 140 so that they can be cut by the cutter head assembly 140. Second, when the extended seedling feeding tray 130 is installed, it drives all the seedling feeding trays to move one station according to the spacing between the seedling feeding trays, so that the extended seedling feeding tray 130 can move to the position corresponding to the cutter head assembly 140, thereby enabling the seedlings on the extended seedling feeding tray 130 to be cut by the cutter head assembly 140 like the seedlings on the basic seedling feeding tray 120 to achieve the seedling throwing action.

[0049] In the operation of the unmanned aerial vehicle (UAV) rice seedling throwing system 100 described in this application embodiment, after the extended rice seedling throwing tray 130 is connected to the end of the basic rice seedling throwing tray 120, since all the basic rice seedling throwing trays 120 have corresponding cutter head assemblies 140, the movement of the cutter head assembly 140, in conjunction with the translation mechanism 150, drives the basic rice seedling throwing tray 120 to move laterally, which can cut off the bottom row of seedlings in each column of the seedlings on the basic rice seedling throwing tray 120. After the bottom row of seedlings on the basic rice seedling throwing tray 120 is cut and thrown, the translation mechanism 150 drives the basic rice seedling throwing tray 120 and the extended rice seedling throwing tray 130 as a whole, so that the seedlings on the extended rice seedling throwing tray 130 move to the position corresponding to the cutter head assembly 140. The cutter head assembly 140 then moves, cutting and throwing the seedlings on the extended rice seedling throwing tray 130 in the same way as cutting the seedlings on the basic rice seedling throwing tray 120.

[0050] It should be noted that during the operation of the unmanned aerial vehicle rice seedling throwing system 100 described in this application, the bottom row of seedlings on the basic seedling delivery tray 120 and the extended seedling delivery tray 130 is cut first, and then the upper row of seedlings is cut. When cutting the upper row of seedlings, the basic seedling delivery tray 120 and the extended seedling delivery tray 130 can be moved to the initial position by the translation mechanism 150, and the seedlings on the basic seedling delivery tray 120 can be cut and thrown first. Alternatively, the translation mechanism 150 can move directly in the opposite direction, and the seedlings on the extended seedling delivery tray 130 can be cut and thrown first. After the seedlings on the extended seedling delivery tray 130 are cut, the seedlings on the basic seedling delivery tray 120 can be cut and thrown.

[0051] Reference Figure 1 , 8As shown, the translation mechanism 150 in this embodiment includes a drive assembly 1501 and a translation mounting plate 1502. The drive assembly 1501 is fixedly mounted on the load frame 110, and the translation mounting plate 1502 is fixedly connected to the basic seedling feeding tray 120. The drive assembly 1501 drives the translation mounting plate 1502 to move the basic seedling feeding tray 120 relative to the load frame 110. The extended seedling feeding tray 130 is fixedly connected to the basic seedling feeding tray 120.

[0052] An extension mounting plate 1303 is provided on the extended seedling tray 130. The extension mounting plate 1303 can dock with the translation mounting plate 1502. When the extension mounting plate 1303 docks with the translation mounting plate 1502, the drive component 1501 can drive the basic seedling tray 120 to move simultaneously, thereby driving the extended seedling tray 130 to move.

[0053] In this embodiment, the extension seedling tray 130 is installed and its movement is driven by the same mechanism as the basic seedling tray 120. This eliminates the need for a separate transverse drive mechanism, simplifying the extension structure of the seedling tray and reducing equipment costs.

[0054] This application provides a specific solution for movably mounting the basic seedling tray 120 and the extended seedling tray 130 onto the load frame 110. Specifically, refer to... Figure 9 As shown, a support frame 1101 is provided on the load frame, and translation tracks 1503 are respectively provided on the basic seedling feeding tray 120 and the extended seedling feeding tray 130. The support frame 1101 is movably connected to the translation track 1503 to support the basic seedling feeding tray 120 and the extended seedling feeding tray 130, and to enable the basic seedling feeding tray 120 and the extended seedling feeding tray 130 to translate relative to the load frame 110. The support frame 1101 serves to support the basic seedling feeding tray 120.

[0055] The connection structure between the support frame 1101 and the translation track 1503 can be various. For example, a slider can be provided on the support frame 1101, and the slider cooperates with the translation track 1503 to achieve a relative sliding connection. In a preferred embodiment of this application, referring to... Figure 9 As shown, a roller 1102 is provided at the end of the support frame 1101, and a groove 15031 is provided on the translation track 1503. The roller 1102 and the groove 15031 cooperate to realize the sliding connection between the basic seedling feeding tray 120 and the load frame 110. In this embodiment, the cooperation between the roller 1102 and the groove 15031 forms a rolling connection between the two, which can reduce the friction between them and make the movement of the basic seedling feeding tray 120 relative to the load frame 110 smoother and less strenuous.

[0056] To ensure the stability of the support frame 1101 in supporting the basic seedling tray 120, in an optional embodiment of this application, the support frame 1101 can be in two rows, and the corresponding translation track 1503 can also be in two rows.

[0057] Or, refer to Figure 9 , 10 As shown, in a preferred embodiment of this application, support rollers 1504 are respectively provided on the basic seedling feeding tray 120 and the extended seedling feeding tray 130. A support guide rail is provided on the load frame 110 corresponding to the support rollers 1504, and the support rollers 1504 can roll on the support guide rails. In this embodiment, the fit between the rollers 1102 and the slide groove 15031 of the support frame 1101 is a clearance fit. When the basic seedling feeding tray 120 and the extended seedling feeding tray 130 tilt under the action of gravity, the support rollers 1504 can abut against the support guide rails to form support, avoiding damage to the rollers 1102.

[0058] For the preferred option, continue to refer to... Figure 9 , 10 As shown, the basic seedling feeding tray 120 and the extended seedling feeding tray 130 are provided with support roller mounting grooves 1505 parallel to the translation track 1503. The support roller 1504 is rotatably installed in the support roller mounting groove 1505, and the support roller 1504 protrudes from the groove of the roller mounting groove to abut against the support track and roll.

[0059] It is understood that the above-described method of installing the base support roller 1504 using the support roller mounting groove 1505 is not intended to limit this application. In other embodiments of this application, the base support roller 1504 can also be installed using a plurality of support roller 1504 mounting brackets.

[0060] In this embodiment, the structure of the driving component 1501 driving the basic seedling feeding tray 120 and the extended seedling feeding tray 130 connected thereto can be that the driving component 1501 is provided with a first transmission member, and the translational mounting plate 1502 is provided with a second transmission member. The first transmission member and the second transmission member cooperate to drive the basic seedling feeding tray 120 to move relative to the load frame 110.

[0061] Specifically, refer to Figure 1As shown, in an optional embodiment of this application, the first transmission component is a transmission gear 15011, and the second transmission component is a transmission rack 15012 that is driven to engage with the transmission gear 15011. By driving the transmission gear 15011 to rotate, the transmission gear 15011 drives the transmission rack 15012 to translate. The base seedling tray 120 and the extended seedling tray 130, which are fixedly connected to the transmission rack 15012, can then synchronously perform translational movements to achieve adjustment of the working position and feeding operation.

[0062] Specifically, refer to Figure 1 , 5 As shown, in this embodiment, a rack mounting seat 15013 is provided on the translation mounting plate 1502, and the transmission rack 15012 is mounted parallel to the translation mounting plate 1502 through the rack mounting seat 15013.

[0063] It should be noted that, in the embodiments of this application, the basic seedling feeding tray 120 and the extended seedling feeding tray 130, in addition to requiring horizontal movement control so that each row of seedlings can correspond to the cutter head assembly 140, also need to perform longitudinal feeding. That is, after the bottom row of seedlings is cut, the entire seedling needs to be moved downwards so that the previous row of seedlings can be fed to the bottom so that it can be cut by the cutter head assembly 140. Therefore, referring to... Figure 7 As shown in the embodiment of this application, the basic seedling tray 120 and the extended seedling tray 130 are respectively provided with conveyor belts 200, and the seedlings are placed on the conveyor belts 200. The conveyor belts 200 are used to transport the seedlings to the direction of the cutter head assembly 140.

[0064] Continue to refer to Figure 7 As shown in the embodiment of this application, the conveyor belt 200 is provided with a plurality of protrusions 201 structures. The back of the protrusions 201 structures forms a recess. One side of the protrusions 201 faces the seedlings and is used to cooperate with the seedlings to fix them on the conveyor belt 200. The recess on the back is used to cooperate with the boss provided on the seedling delivery transmission mechanism 202 that drives the conveyor belt 200 to ensure the rotation of the conveyor belt 200.

[0065] Reference Figure 1 , 5 As shown, this embodiment of the application also includes a seedling delivery drive mechanism 203 for driving the conveyor belt 200 to rotate. The seedling delivery drive mechanism 203 includes a seedling delivery power mechanism and a seedling delivery transmission mechanism 202. The seedling delivery power mechanism is connected to the seedling delivery transmission mechanism 202. The seedling delivery transmission mechanism 202 cooperates with the conveyor belt 200 to drive the conveyor belt 200 to move.

[0066] The seedling delivery transmission mechanism 202 includes a basic transmission rod 2021 and an extended transmission rod 2022. One end of the basic transmission rod 2021 is connected to the seedling delivery power mechanism, and the other end can be selectively connected to the extended transmission rod 2022. The extended transmission rod 2022 drives the conveyor belt 200 on the extended seedling delivery tray 130 to rotate and deliver seedlings.

[0067] It is understood that a transmission connection needs to be established between the basic transmission rod 2021 and the extended transmission rod 2022 so that the driving force of the seedling feeding power mechanism can be transmitted to the extended transmission rod 2022 through the basic transmission rod 2021. The seedling feeding power mechanism can simultaneously drive the conveyor belt 200 on the basic seedling feeding tray 120 and the extended seedling feeding tray 130 to achieve vertical feeding of seedlings. The transmission connection between the basic transmission rod 2021 and the extended transmission rod 2022 can be achieved through a transmission key, or through a coupling.

[0068] Specifically, refer to Figure 3 As shown, in this application, the end of the extended transmission rod 2022 extends into a transmission rod mounting seat, and a keyway 204 is provided on it. The corresponding basic transmission rod 2021 is also provided with a keyway 204, and the end of the basic transmission rod 2021 is recessed into the transmission rod mounting seat, so that the extended transmission rod 2022 can be inserted into the transmission rod mounting seat on the opposite side. With the use of the transmission key, when the basic transmission rod 2021 rotates, the extended transmission rod 2022 can rotate synchronously.

[0069] This application also provides a drone, as shown in the embodiments. Figure 11 As shown, it includes a fuselage 300 and a load connected to the underside of the fuselage 300, the load being the unmanned aerial vehicle rice-throwing system 100 as described above.

[0070] In this application, two sets of drone rice-throwing systems 100 are symmetrically arranged either front-to-back or left-to-right below the fuselage 300. The two sets of drone rice-throwing systems 100 have the same structure, but are installed in opposite directions and have opposite horizontal feeding directions. This makes the change of the drone's center of gravity symmetrical during operation as the rice is thrown, thereby reducing the occurrence of drone malfunctions.

[0071] It is understood that in the drones described in the embodiments of this application, the number of extended seedling trays 130 added to each of the two drone seedling throwing systems 100 should be the same.

[0072] That is, when it is necessary to expand the seedling delivery tray, an extended seedling delivery tray 130 with one seedling delivery tray can be added to each group of UAV seedling throwing system 100, or an extended seedling delivery tray 130 with two seedling delivery trays can be added at the same time.

[0073] The drone in this embodiment of the application uses the above-mentioned drone seedling throwing system 100 with seedling tray expansion function, which can greatly increase the seedling loading capacity of the drone and improve the working efficiency of drone sowing.
