[0038] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0039] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] The seedling delivery tray is used to place pot seedlings or blanket seedlings for scattering by the seedling throwing system, and the cutter head assembly is used to detach the seedlings from the seedling delivery tray for subsequent seedling throwing operations. When only the seedling delivery tray is provided, the loading quantity of the drone seedling throwing system is limited, and since usually a group of seedling delivery trays corresponds to a group of cutter head assemblies, adding cutter head assemblies at the same time as adding seedling delivery trays not only increases the equipment cost, but also increases the load on the transportation equipment, resulting in its inability to meet the needs of assembling more seedling delivery trays in terms of load-bearing capacity.

[0042] Reference Figure 1-10 As shown, an embodiment of the present application provides a drone seedling-transporting system 100, comprising a load frame 110, a basic seedling-transporting tray 120 arranged in the load frame 110, and a cutter head assembly 140 arranged corresponding to the basic seedling-transporting tray 120, wherein the basic seedling-transporting tray 120 is movably arranged relative to the load frame 110, and an end of the basic seedling-transporting tray 120 can be connected to an extended seedling-transporting tray 130, after which the extended seedling-transporting tray 130 can be moved to the cutter head assembly 140, and the seedlings can be cut and transported by means of the cutter head assembly 140.

[0043] In the embodiment of the present application, the basic seedling delivery tray 120 is a seedling delivery tray assembled with the load frame 110 under normal conditions, and a one-to-one corresponding cutter head assembly 140 is provided in the drone seedling throwing system 100. Under normal working conditions, each cutter head assembly 140 cuts the seedlings on the corresponding basic seedling delivery tray 120 to separate it from the basic seedling delivery tray 120. The extended seedling delivery tray 130 is used to be assembled on the basic seedling delivery tray 120. In the drone seedling throwing system 100, there is no dedicated cutter head assembly 140 specifically provided for the extended seedling delivery tray 130. During use, when the seedlings on the basic seedling delivery tray 120 are all cut and thrown, the extended seedling delivery tray 130 is fed to the position of the original basic seedling delivery tray 120, and the cutter head assembly 140 at this position continues to work to cut and throw the seedlings on the extended seedling delivery tray 130.

[0044] By providing an extended seedling delivery tray 130, and the extended seedling delivery tray 130 and the basic seedling delivery tray 120 share the cutter head assembly 140, while the seedling loading capacity of the drone seedling throwing system 100 is increased, the number of cutter head assemblies 140 used is not increased, thereby improving the working efficiency of the drone seedling throwing system 100, avoiding the increase in weight and cost of the cutter head assembly 140, and having good use effect and economic benefits.

[0045] In order to install the extended seedling tray 130 in the present application, it is necessary to fix the extended seedling tray 130 to the basic seedling tray 120 and connect the translation mechanism 150 of the basic seedling tray 120 and the seedling feeding mechanism to the extended seedling tray 130 to realize the sharing of each driving mechanism. Figure 1 , 2 As shown in Figures 4 and 5, in the embodiment of the present application, the form of fixing the extended seedling delivery tray 130 to the basic seedling delivery tray 120 is that a hook 1301 and a fixing pin 1302 are provided on the extended seedling delivery tray 130, and a pin hole corresponding to the fixing pin 1302 is provided on the basic seedling delivery tray 120, and the extended seedling delivery tray 130 is hung on the basic seedling delivery tray 120 through the hook 1301, and is positioned by the fixing pin 1302. In this embodiment, the fixing pin 1302 cooperates with the pin hole to play a positioning role, and at the same time, it also bears the weight of the extended seedling delivery tray 130, and cooperates with the hook 1301 to achieve a fixed connection between the extended seedling delivery tray 130 and the basic seedling delivery tray 120.

[0046] It is understandable that the connection method between the extended seedling delivery tray 130 and the basic seedling delivery tray 120 is not a limitation of the present application. In other embodiments, other solutions that can be thought of by those skilled in the art can be used to achieve a fixed connection between the basic seedling delivery tray 120 and the extended seedling delivery tray 130.

[0047] At the same time, the embodiment of the present application also provides a method for implementing the horizontal feeding of the basic seedling feeding tray 120 and the extended seedling feeding tray 130, referring to Figure 1 As shown, the drone seedling planting system 100 described in the embodiment of the present application also includes a translation mechanism 150 for driving the basic seedling delivery tray 120 to move horizontally. After the extended seedling delivery tray 130 is connected to the basic seedling delivery tray 120, the translation mechanism 150 is shared with the basic seedling delivery tray 120.

[0048] The horizontal moving mechanism in the present application has two main functions. One is to move the seedling delivery trays row by row according to the width of a single row of seedlings so that a row of seedlings corresponds to the cutter head assembly 140 to facilitate cutting by the cutter head assembly 140. The other function is to drive all the seedling delivery trays to move one station as a whole according to the seedling delivery tray spacing when the extended seedling delivery tray 130 is installed, so that the extended seedling delivery tray 130 can be moved to the position corresponding to the cutter head assembly 140, so that the seedlings on the extended seedling delivery tray 130 can be cut by the cutter head assembly 140 to realize the seedling throwing action like the seedlings on the basic seedling delivery tray 120.

[0049] During the operation of the drone seedling-casting system 100 described in the embodiment of the present application, after the end of the basic seedling-casting tray 120 is connected to the extended seedling-casting tray 130, since all the basic seedling-casting trays 120 have corresponding cutter head assemblies 140, the cutter head assembly 140 cooperates with the translation mechanism 150 to drive the basic seedling-casting tray 120 to feed horizontally, so as to cut off the bottom row of seedlings in each column of the blanket seedlings on the basic seedling-casting tray 120. After the cutting and casting of the bottom row of seedlings on the basic seedling-casting tray 120 is completed, the translation mechanism 150 drives the basic seedling-casting tray 120 and the extended seedling-casting tray 130 to move as a whole, so that the seedlings on the extended seedling-casting tray 130 move to the position corresponding to the cutter head assembly 140, and the cutter head assembly 140 acts to cut and cast the seedlings on the extended seedling-casting tray 130 just like cutting the seedlings on the basic seedling-casting tray 120.

[0050] It should be pointed out that during the operation of the drone seedling-transporting system 100 described in the present application, the bottom row of seedlings on the basic seedling-transporting tray 120 and the extended seedling-transporting tray 130 are first cut, and then the upper row of seedlings is cut. When cutting the upper row of seedlings, the basic seedling-transporting tray 120 and the extended seedling-transporting tray 130 can be driven by the translation mechanism 150 to move to the initial position, and the seedlings on the basic seedling-transporting tray 120 are cut and transported first, or the translation mechanism 150 can be directly moved in the opposite direction, and the seedlings on the extended seedling-transporting tray 130 are cut and transported first. After the cutting of the seedlings on the extended seedling-transporting tray 130 is completed, the seedlings on the basic seedling-transporting tray 120 are cut and transported.

[0051] Reference Figure 1 , 8As shown, the translation mechanism 150 in the embodiment of the present application includes a driving component 1501 and a translation mounting plate 1502, the driving component 1501 is fixedly arranged on the load frame 110, the translation mounting plate 1502 is fixedly connected to the basic seedling sending tray 120, and the driving component 1501 drives the translation mounting plate 1502 to drive the basic seedling sending tray 120 to move relative to the load frame 110, and the extended seedling sending tray 130 is fixedly connected to the basic seedling sending tray 120.

[0052] The extended seedling delivery tray 130 is provided with an extended mounting plate 1303, and the extended mounting plate 1303 can be docked with the translation mounting plate 1502. When the extended mounting plate 1303 is docked with the translation mounting plate 1502, the driving component 1501 can synchronously drive the extended seedling delivery tray 130 to move when driving the basic seedling delivery tray 120 to move.

[0053] The embodiment of the present application adopts a solution in which after the extended seedling delivery tray 130 is installed, its movement adopts the same driving mechanism as the basic seedling delivery tray 120, and there is no need to configure a separate lateral driving mechanism, so that the extended structure of the seedling delivery tray is simplified and the equipment cost is reduced.

[0054] The embodiment of the present application provides a specific solution for movably mounting the basic seedling tray 120 and the extended seedling tray 130 on the load frame 110. For details, refer to Fig. 9 As shown, a support frame 1101 is provided on the load frame, and translation rails 1503 are respectively provided on the basic seedling delivery tray 120 and the extended seedling delivery tray 130. The support frame 1101 is connected with the translation rails 1503 for relative movement, and is used to support the basic seedling delivery tray 120 and the extended seedling delivery tray 130, and enable the basic seedling delivery tray 120 and the extended seedling delivery tray 130 to translate relative to the load frame 110. The support frame 1101 plays a role in supporting the basic seedling delivery 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 relative sliding connection. Fig. 9 As shown, a roller 1102 is provided at the end of the support frame 1101, and a slide groove 15031 is provided on the translation track 1503. The roller 1102 cooperates with the slide groove 15031 to realize the sliding connection between the basic seedling delivery tray 120 and the load frame 110. In this embodiment, the cooperation between the roller 1102 and the slide groove 15031 forms a rolling connection between the two, which can reduce the friction between the two, so that the movement of the basic seedling delivery tray 120 relative to the load frame 110 is smoother and more labor-saving.

[0056] In order to ensure the stability of the support frame 1101 in supporting the basic seedling delivery tray 120, in an optional embodiment of the present application, the support frame 1101 can be in two rows, and the corresponding translation rails 1503 can also be in two rows.

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

[0058] Preferably, continue to refer to Fig. 9 , 10 As shown, the basic seedling delivering tray 120 and the extended seedling delivering tray 130 are provided with a support roller mounting groove 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 notch of the roller mounting groove to roll against the support track.

[0059] It is understandable that the above-mentioned method of installing the basic support roller 1504 using the support roller mounting groove 1505 is not intended to be a limitation of the present application. In other embodiments of the present application, the basic support roller 1504 can also be installed by using a plurality of support roller 1504 mounting brackets.

[0060] In this embodiment, the driving component 1501 drives the basic seedling delivery tray 120 and the extended seedling delivery tray 130 connected thereto. A first transmission member is provided on the driving component 1501, and a second transmission member is provided on the translation mounting plate 1502. The first transmission member cooperates with the second transmission member to drive the basic seedling delivery tray 120 to move relative to the load frame 110.

[0061] Specifically, refer to Figure 1As shown, in an optional embodiment of the present application, the first transmission member is a transmission gear 15011, and the second transmission member is a transmission rack 15012 that is in transmission cooperation with the transmission gear 15011. By driving the transmission gear 15011 to rotate, the transmission gear 15011 drives the transmission rack 15012 to translate, and the basic seedling delivery tray 120 and the extended seedling delivery tray 130 that are relatively fixedly connected to the transmission rack 15012 can synchronously translate 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 installed parallel to the translation mounting plate 1502 through the rack mounting seat 15013.

[0063] It should be noted that in the embodiment of the present application, the basic seedling feeding tray 120 and the extended seedling feeding tray 130 not only need to be horizontally moved to control each row of seedlings to correspond to the cutter head assembly 140, but also need to be longitudinally fed, that is, after the seedlings in the bottom row are cut, the seedlings need to be moved downward as a whole, so that the seedlings in the upper row are fed to the bottom so that they can be cut by the cutter head assembly 140. Therefore, referring to Figure 7 As shown, in the embodiment of the present application, a conveyor belt 200 is respectively provided on the basic seedling delivery tray 120 and the extended seedling delivery tray 130 , and the seedlings are arranged on the conveyor belt 200 . The conveyor belt 200 is used to transport the seedlings toward the cutter head assembly 140 .

[0064] Continue to refer to Figure 7 As shown, the conveyor belt 200 described in the embodiment of the present application is provided with a plurality of protrusions 201 structures, and pits are formed on the back of the protrusion 201 structure. One side of the protrusion 201 faces the blanket seedlings and is used to cooperate with the blanket seedlings to fix them on the conveyor belt 200, and the pits on the back side are used to cooperate with the bosses 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, the embodiment of the present application also includes a seedling sending drive mechanism 203 for driving the conveyor belt 200 to rotate, and the seedling sending drive mechanism 203 includes a seedling sending power mechanism and a seedling sending transmission mechanism 202. The seedling sending power mechanism is connected to the seedling sending transmission mechanism 202, and the seedling sending 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 transmission-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 plate 130 to rotate and transport the seedlings.

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

[0068] Specifically, refer to Figure 3 As shown, in the present application, the end of the extended transmission rod 2022 extends out of the transmission rod mounting seat, and a key groove 204 is provided on it. The corresponding basic transmission rod 2021 is also provided with a key groove 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. In conjunction with the use of the transmission key, when the basic transmission rod 2021 rotates, the extended transmission rod 2022 can rotate synchronously.

[0069] At the same time, the present application embodiment also provides a drone, referring to Fig.11 As shown, it includes a fuselage 300 and a load connected below the fuselage 300, and the load is the drone rice seedling throwing system 100 as described above.

[0070] In the present application, two groups of drone seedling throwing systems 100 can be set symmetrically front to back or left to right under the fuselage 300. The two groups of drone seedling throwing systems 100 have the same structure, but are installed in opposite directions and have opposite horizontal feeding directions. This allows the center of gravity of the drone to change symmetrically during operation as the seedling throwing proceeds, thereby reducing the occurrence of drone clarity issues.

[0071] It is understandable that, in the drone described in the embodiment of the present application, the number of extended seedling delivery trays 130 added to each of the two drone seedling throwing systems 100 should be the same.

[0072] That is, when the seedling delivery tray needs to be expanded, an extended seedling delivery tray 130 with one seedling delivery tray can be added to each group of drone seedling throwing systems 100, or an extended seedling delivery tray 130 with two seedling delivery trays can be added at the same time.

[0073] The drone of the embodiment of the present application adopts the above-mentioned drone seedling planting system 100 with the seedling delivery tray expansion function, which can greatly increase the seedling loading capacity of the drone and improve the work efficiency of drone sowing.

[0074] In the description of this article, it should be understood that the terms "upper", "lower", "left", "right", etc., and other directions or positional relationships are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of this application. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0075] In the description of this specification, the description with reference to the terms "an embodiment", "example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention.
