Description

Technical Field

[0001] This invention relates to the technical field of unmanned equipment, and more particularly to a modular battery loading mechanism and an agricultural drone. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants, and they generally use electricity as their power source.

[0003] In related technologies, agricultural drones generally install batteries in the battery compartment reserved in the main body of the device. However, due to the relatively fixed position of the battery compartment on the agricultural drone and the relatively fixed number of batteries that the battery compartment can carry, the battery compartment cannot provide more battery carrying space for the agricultural drone, and the scope of expansion is limited. This results in the single and fixed use scenario of agricultural drones, the applicable scenarios are also relatively fixed, and the efficiency of performing corresponding tasks is relatively low. Summary of the Invention

[0004] The purpose of this invention is to provide a modular battery loading mechanism and an agricultural drone, which solves the problem of limited and fixed usage scenarios for agricultural drones due to the limited space for battery mounting by using a modularly designed mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, a modular battery loading mechanism is provided, comprising:

[0007] The main body of the mechanism is provided with at least two expansion slots, which are used to provide space for mounting the battery. A slot is provided on one side of the main body of the mechanism to communicate with the expansion slots, which are used to provide space for the battery to enter and exit the expansion slots.

[0008] The bottom of the mechanism body is provided with a first fixing structure, and the mechanism body can be fixedly installed on the agricultural drone through the first fixing structure;

[0009] When two or more of the aforementioned mechanism bodies are installed on an agricultural drone, each of the aforementioned mechanism bodies and each of the aforementioned expansion slots are arranged sequentially along the width direction of the agricultural drone.

[0010] As an optional implementation, when the mechanism body is mounted on the agricultural drone, the mechanism body is located on top of the agricultural drone.

[0011] As an optional implementation, the first fixing structure is provided on both opposite sides of the bottom of the mechanism body.

[0012] As an optional implementation, the bottom of the mechanism body is also provided with a first limiting structure, which is configured to constrain the relative position between the mechanism body and the agricultural drone.

[0013] As an optional implementation, a first guide structure is provided in the expansion slot, which is used to constrain the direction of the battery entering and exiting the expansion slot.

[0014] As an optional implementation, the first guide structure is a guide rib, which protrudes from the groove wall of the expansion groove and extends in the direction close to and away from the groove opening.

[0015] As an optional implementation, the surface of the guide rib is formed with a first guide surface and a second guide surface connected along its extension direction, the first guide surface being disposed close to the groove and the second guide surface being disposed away from the groove;

[0016] The distance between the first guide surface and the wall of the corresponding expansion groove is less than the distance between the second guide surface and the wall of the corresponding expansion groove, and the first guide surface and the second guide surface are connected by a transition surface.

[0017] As an optional implementation, the mechanism body includes two side plates that are opposite to each other and spaced apart, and an end plate connected between the two side plates;

[0018] A partition is provided between the two side plates, and the two side plates, the end plate and the partition cooperate to define two expansion slots. The slot is formed at the end of the expansion slot away from the end plate, and the first fixing structure is provided in one of the side plates.

[0019] Secondly, an agricultural drone is provided, comprising:

[0020] The equipment body, the upper part of which has a loading section; and

[0021] At least one modular battery loading mechanism as described in the first aspect, the mechanism body being detachably mounted to the loading section;

[0022] When there are at least two modular battery loading mechanisms, the mechanism body is at least partially disposed in the loading section along the width direction of the device body.

[0023] As an optional implementation, the head and tail directions of the device body located on the loading part are perpendicular to its width direction;

[0024] The length direction of the expansion slot is consistent with the head and tail direction of the device body, and the width direction of the expansion slot is perpendicular to both the head and tail direction and the width direction of the device body.

[0025] As an optional implementation, the slot faces the tail of the device body.

[0026] As an optional implementation, the loading part is provided with a second fixing structure, which is adapted to the first fixing structure, and the mechanism body can be fixedly installed on the device body through the first fixing structure and the second fixing structure.

[0027] As an optional implementation, the first fixing structure is a positioning hole distributed on opposite sides of the bottom of the mechanism body;

[0028] The second fixing structure is a threaded hole opened on the loading part corresponding to the position of each of the positioning holes.

[0029] As an optional implementation, the bottom of the mechanism body is further provided with a first limiting structure, and the loading part is provided with a second limiting structure that is adapted to the first limiting structure at the position corresponding to the first limiting structure.

[0030] As an optional implementation, the first limiting structure is at least two limiting ribs, the two limiting ribs being spaced apart along the width direction of the expansion groove and extending along the length direction of the expansion groove;

[0031] The second limiting structure is a limiting groove formed in the loading part. The opposite side walls of the limiting groove extend along the head and tail direction of the equipment body. When the mechanism body is loaded in the loading part, the side walls of the two limiting ribs that are opposite to each other are respectively relative to the opposite two groove walls of the limiting groove, and the corresponding limiting ribs are in clearance fit with the groove wall of the limiting groove.

[0032] As an optional implementation, when there are at least two modular battery loading mechanisms, the mechanism bodies are arranged sequentially in the loading section along the width direction of the device body.

[0033] As an optional implementation, when there are at least two modular battery loading mechanisms, at least one side of the device body is further provided with an extension mounting member, and the upper part of the extension mounting member forms a support surface that connects with the loading part.

[0034] One part of the mechanism body is mounted to the equipment body via the loading part, and another part of the mechanism body is placed on the support surface.

[0035] As an optional implementation, the extension mounting component is further provided with a third limiting structure on the side of the support surface away from the device body. When the mechanism body is placed on the support surface, the extension mounting component is limited and engaged with the mechanism body through the third limiting structure.

[0036] The beneficial effects of the present invention are as follows: the main body of the modular battery loading mechanism can be externally mounted on the agricultural drone through the first fixed structure, making use of the relatively extra space outside the agricultural drone, thereby allowing the agricultural drone to provide a larger loading position for the main body. The agricultural drone can carry different numbers of main bodies according to different situations, improving the expandability of the number of batteries and broadening the application scenarios of the product.

[0037] By setting at least two expansion slots on the main body of the mechanism, the battery mounting space is made larger and more flexible based on the modular design of the main body. The battery can be quickly installed and removed from the main body under different conditions, so as to meet the endurance requirements and improve the efficiency of agricultural drones in performing corresponding tasks.

[0052] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] In the description of this invention, unless otherwise explicitly 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.

[0054] In this invention, unless otherwise explicitly 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 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 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.

[0055] Agricultural drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants. They are generally powered by electricity and can perform spraying operations, such as spraying pesticides, seeds, and powders, under the control of ground remote control or navigation flight control.

[0056] As can be seen from the background technology, in the relevant technologies of agricultural drones, the equipment generally installs the battery in the battery compartment reserved in the main body of the equipment. However, due to the relatively fixed position of the battery compartment on the agricultural drone and the relatively fixed number of batteries that the battery compartment can carry, the battery compartment cannot provide more battery carrying space for the agricultural drone, and the expansion range is limited. This results in the single and fixed use scenario of the agricultural drone, the applicable scenario is also relatively fixed, and the efficiency of performing the corresponding tasks is relatively low.

[0057] Therefore, this embodiment provides a modular battery loading mechanism. Through the modular design of the mechanism body, the application of the mechanism body on agricultural drones is more flexible, so as to provide a larger battery mounting space and solve the problem of single and fixed application scenarios of agricultural drones.

[0058] Please refer to the appendix. Figure 1 The modular battery loading mechanism includes a mechanism body 10, which serves as the supporting foundation for the modular battery loading mechanism. It is used to install on the agricultural drone to provide mounting space that is compatible with the structure of the corresponding battery 30. The battery 30 is mounted on the mechanism body 10 and supported by the mechanism body 10. At the same time, it achieves electrical connection with the corresponding agricultural drone through the mechanism body 10, so as to provide power to the agricultural drone.

[0059] Following the above embodiment, the main body 10 of the mechanism is provided with at least two expansion slots 11. The expansion slots 11 are used to provide the battery mounting space. In a specific usage scenario, the battery 30 can achieve a relatively stable state with the main body 10 through the expansion slots 11. It can be understood that in order to achieve the corresponding matching state, the expansion slot 11 can be fitted with the surface of the battery 30 through a gap, or the battery 30 can be constrained in the position of the expansion slot 11 by setting a matching limiting structure on the wall of the expansion slot 11. When the expansion slot 11 is equipped with the battery 30, the agricultural drone can achieve an electrical connection with the battery 30 directly or indirectly. For example, the agricultural drone can directly connect to the battery 30 through an interface led out from its internal motherboard, or, after the agricultural drone is electrically connected to the main body 10 through the corresponding interface, a socket can be set at the position corresponding to the expansion slot 11 of the main body 10 so that the battery 30 can be electrically connected to the agricultural drone through the battery socket after entering the expansion slot 11.

[0060] By providing at least two expansion slots 11 on the main body 10, the agricultural drone can still provide at least two expansion slots 11 for mounting batteries 30 even when only one main body 10 is mounted. This can meet the needs of mounting a relatively small number of batteries 30, while also providing the mounting space required for battery expansion, thus meeting the needs of the agricultural drone in certain operating scenarios.

[0061] It is worth mentioning that, under the current environment of battery product standardization, this embodiment can adapt the structure of the expansion slot 11 to the structure of the standardized battery product, so that the structure of each expansion slot 11 is suitable for the existing standardized battery product. The modular battery loading mechanism can be adapted to the existing standardized battery product, which is conducive to the direct application of the modular battery loading mechanism on agricultural drones and saves the design cost and production cost of redeveloping battery products that match the mechanism.

[0062] Please continue to refer to the appendix. Figure 1Each expansion slot 11 located on the same main body 10 is arranged side by side along a specified direction. The arrangement of each expansion slot 11 on the main body 10 can be adapted to the specific structural form of the agricultural drone. For example, when there are two expansion slots 11, the two expansion slots 11 can be arranged side by side in the width direction, length direction or any other direction of the main body 10. When there are three or more expansion slots 11, each expansion slot 11 can also be arranged sequentially in the width direction, length direction or any other direction of the main body 10. In addition, when there are three or more expansion slots 11 on the main body 10, the connecting line formed by the sequential connection between each expansion slot 11 can be a straight line or an arc on the main body 10.

[0063] One side of the main body 10 of the mechanism has a slot that connects to the expansion slot 11. The slot is used to provide space for the battery 30 to enter and exit the expansion slot 11. Each battery 30 can be mounted into the corresponding expansion slot 11 through the slot and arranged on the agricultural drone according to the arrangement of the expansion slot 11, so as to make full use of the external space of the agricultural drone. On this basis, each main body 10 of the mechanism on the agricultural drone can also open the slot on each side of the expansion slot 11, so that the battery 30 corresponding to different expansion slots 11 can be installed and removed from the expansion slot 11 in different ways and directions according to the position of the slot, thereby avoiding interference between the battery 30 and the equipment during the installation and removal process.

[0064] Please refer to the attached document. Figures 1-5 The bottom of the main body 10 is provided with a first fixing structure 12. The main body 10 can be fixedly installed on the agricultural drone through the first fixing structure 12. Since the first fixing structure 12 is located at the bottom of the main body 10, when the main body 10 is installed on the agricultural drone, the main body 10 will protrude outward from the installation position provided by the agricultural drone. Compared with the related technology that integrates the battery compartment into the device, the present invention utilizes the relatively extra space outside the agricultural drone to provide corresponding loading space for the main body 10. The installation of the main body 10 is not limited by the size and related structural form of the agricultural drone's main body 20, thereby allowing the agricultural drone to provide a larger loading position for the main body 10. The agricultural drone can carry different numbers of main bodies 10 according to different situations, improving the expandability of the number of batteries 30 and broadening the application scenarios of the product. Furthermore, as can be seen from the above embodiments, the present invention also provides at least two expansion slots 11 on the main body 10, which, based on the modular design of the main body 10, allows for a larger and more flexible space for battery mounting. The battery 30 can be quickly installed and removed from the main body 10 under different circumstances, thereby meeting the battery life requirements while improving the efficiency of the agricultural drone in performing corresponding tasks.

[0065] Refer to the instruction manual. Figures 1-10 In one embodiment, taking the scheme of mounting the mechanism body 10 on the upper part of the agricultural drone through the first fixing structure 12 as an example, the bottom of the mechanism body 10 is connected to the agricultural drone and protrudes along the upper direction of the agricultural drone. The upper space of the agricultural drone can provide a wider and more flexible battery mounting space for the mechanism body 10. The agricultural drone can selectively install one or more mechanism bodies 10 according to its current operation task requirements, and selectively mount the battery 30 in the corresponding expansion slot 11 according to the number of expansion slots 11 provided by the mechanism body 10, so that the power provided by the battery 30 or battery pack can match the operation task to be performed by the drone, thereby reducing or even avoiding the charging operation of the agricultural drone during the operation task, thereby improving the task execution efficiency of the equipment and expanding the application scenarios of the equipment.

[0066] Based on the above, it can be understood that agricultural drones can selectively install one or more mechanism bodies 10 according to the current operational task requirements. When two or more mechanism bodies 10 are installed on the agricultural drone, each mechanism body 10 and each expansion slot 11 are arranged sequentially along the width direction of the agricultural drone to utilize the space of the agricultural drone's frame in the width direction to mount the modular battery loading mechanism, thereby avoiding excessive impact on the agricultural drone's flight control device, dispersing system, and center of gravity.

[0067] For ease of understanding, in this embodiment, taking the modular battery loading mechanism and agricultural drone as examples where the mechanism body 10 is installed on the equipment body 20, the side of each component closest to the head of the equipment body 20 is the front side 33 of each component, i.e., the attachment. Figure 1 , Figure 6 , Figure 8 The direction indicated by the middle arrow, "forward," refers to the side closest to the rear of the main body 20, which is the rear side 35 of each component, i.e., the appendix. Figure 1 , Figure 6 , Figure 8 The direction indicated by the middle arrow is "back". When the agricultural drone is placed normally parallel to the horizontal plane, the side located at the top of the main body 20 is defined as the upper side of each component, i.e., the attachment. Figure 1 , Figure 6 , Figure 8 The direction indicated by the middle arrow, "up," is defined as the lower side of each component, i.e., the side closer to the lower part of the device body 20. Figure 1 , Figure 6 , Figure 8 The direction the middle arrow points to is "down".

[0068] As an optional implementation method for the mechanism body 10 when installed on an agricultural drone, the mechanism body 10 is located on the upper part of the drone's fuselage, utilizing the space above the drone's fuselage as a mounting space for the modular battery loading mechanism. It should be noted that existing agricultural drone fuselages generally have a hollow frame structure. In the prior art, the hollow portion of this frame structure is used to provide mounting space for the battery 30. However, this arrangement limits the number of batteries 30 that can be installed on the drone to the size of the fuselage. That is, if more batteries 30 are to be installed on the drone, the frame structure must be enlarged, resulting in an increase in the overall size of the drone. This solution places the mechanism body 10, which mounts the battery 30, on the upper part of the agricultural drone. This reduces the coupling between the battery 30 and the drone's fuselage, allowing the battery 30 to be offset from the fuselage onto different planes. This solves the problem of the battery 30's mounting space being limited by the fuselage size, thus enabling the scalability of the battery 30.

[0069] Please continue to refer to the appendix. Figures 1-5 In one embodiment, a first fixing structure 12 is provided on both opposite sides of the bottom of the mechanism body 10.

[0070] In the above embodiments, the first fixing structure 12 is disposed on opposite sides of the bottom of the mechanism body 10, which can effectively improve the assembly stability of the mechanism body 10 on the plant protection drone. The mechanism body 10 can be directly or indirectly installed on the plant protection drone through the first fixing structure 12. For example, in the direct installation embodiment, the first fixing structure 12 can be configured to be adapted to the original structure of the plant protection drone to save the cost of processing a matching fixing structure on the plant protection drone. In the indirect installation embodiment, the plant protection drone can be installed by setting a second fixing structure 211 adapted to the first fixing structure 12, so that the two can be installed through the first fixing structure 12 and the second fixing structure 211.

[0071] The first fixing structure 12 can be located on opposite sides of the mechanism body 10 along the front-back direction or along the left-right direction (located on opposite sides of the bottom of the mechanism body 10 perpendicular to its front-back direction). This ensures that the parts of the mechanism body 10 near either end can form a stable connection with the agricultural drone, reducing or even preventing the risk of the mechanism body 10 and its battery 30 detaching from the agricultural drone. Of course, in some embodiments, the first fixing structure 12 can be located on the front-back opposite sides and the left-right opposite sides of the bottom of the mechanism body 10 to further improve the stability of the assembly between the mechanism body 10 and the fuselage. However, it should be noted that since the battery 30 is relatively heavy when the main body 10 is loaded with the main body 10, the weight of the battery 30 will be transferred to the body through the main body 10. That is, the main body 10 will be pressed against the body by the battery 30 to a certain extent, which actually plays a certain role in stabilization. Therefore, the design of the fixing structure between the main body 10 and the body can be appropriately reduced, which reduces the assembly cost and makes the equipment structure simpler and more compact. For example, in this embodiment, the main body 10 is provided with a first fixing structure 12 extending in the front-back direction on both the left and right sides of its bottom, which adapts to the top structure of the agricultural drone and ensures the assembly stability between the two.

[0072] For example, the mechanism body 10 can adopt a relatively common technical solution in the relevant field as the first fixing structure 12 located at its bottom. For example, a snap-fit ​​structure, a tenon structure, a screw connection structure, etc. can all be used as specific implementations of the first fixing structure 12. This embodiment does not impose strict limitations here.

[0073] As an implementation that can be carried out independently of the aforementioned scheme regarding the first fixing structure 12, and also in parallel with the aforementioned scheme regarding the first fixing structure 12, such as... Figures 1-5 As shown, a first limiting structure 13 is also provided at the bottom of the mechanism body 10. The first limiting structure 13 is configured to constrain the relative position between the mechanism body 10 and the agricultural drone.

[0074] In the embodiment where a first limiting structure 13 is provided at the bottom of the mechanism body 10, during the installation process of the mechanism body 10 and the plant protection drone, the first limiting structure 13 mainly plays the role of pre-positioning between the mechanism body 10 and the plant protection drone. After the mechanism body 10 is limited and cooperated with the plant protection drone through the first limiting structure 13, the relative position of the mechanism body 10 and the plant protection drone is determined, and the specific position of the first fixing structure 12 on the plant protection drone is also constrained, thereby making the installation process of the first fixing structure 12 on the plant protection drone more precise and simple.

[0075] In addition, the mechanism body 10 achieves a limiting cooperation with the plant protection drone through the first limiting structure 13, so that the mechanism body 10 and the plant protection drone can not only rely on the first fixing structure 12 to achieve a fixed connection between the two, but also rely on the first limiting structure 13 to achieve the transmission of interaction force. This reduces the stress on the first fixing structure 12 and makes the installation state of the mechanism body 10 on the plant protection drone more stable.

[0076] It is understood that, similar to the principle of the first fixed structure 12, the mechanism body 10 can adopt a relatively common technical solution in the relevant field as the first limiting structure 13 located at its bottom. For example, the limiting block / groove structure, the guide slider / slide rail structure, the buckle structure, etc. can all be used as specific implementations of the first limiting structure 13. This embodiment will not be strictly limited here.

[0077] It should be noted that when the mechanism body 10 is pre-positioned and assembled with the plant protection drone through the first limiting structure 13, the mechanism body 10 and the plant protection drone should retain at least one degree of freedom of relative movement in one direction, so as to reduce the difficulty of pre-positioning and assembly between the mechanism body 10 and the plant protection drone.

[0078] As an implementation method that can be based on any of the above embodiments, please refer to the appendix. Figures 1-5 The expansion slot 11 is provided with a first guide structure 14. During the process of the battery 30 entering and exiting the expansion slot 11 through the slot opening, the first guide structure 14 is used to constrain the direction of the battery 30 entering and exiting the expansion slot 11, so as to improve the stability of the battery 30 during the disassembly and assembly process with the mechanism body 10, and reduce the collision between the battery 30 and the mechanism body 10 during the disassembly and assembly process and when it is mounted in the expansion slot 11.

[0079] Based on the above, it can be understood that in one embodiment, when the battery 30 is in the expansion slot 11 and is electrically connected to the body through the socket, the first guide structure 14 can also be used to constrain the battery 30, that is, the first guide structure 14 and the battery 30 are matched in a limiting manner so that the battery 30 is stably connected to the socket located in the expansion slot 11.

[0080] For example, the first guide structure 14 should at least provide the battery 30 with a degree of freedom of movement in the direction of entering and exiting the expansion slot 11 through the slot opening, so that the battery 30 can complete the connection with and detachment from the mechanism body 10 under its guidance. The specific structure of the first guide structure 14 can adopt relatively commonly used technical solutions in related fields, such as guide protrusions, guide slots, guide rails, etc., and this embodiment will not be strictly limited here.

[0081] It should be understood that the specific structural form of the first guide structure 14 should be adapted to the structure of the corresponding standardized battery product in order to avoid mutual interference between the batteries 30 and the main body 10 during disassembly and assembly.

[0082] In this way, the battery 30, the mechanism body 10, and the agricultural drone are stably connected in sequence through the first fixing structure 12, the first limiting structure 13, and the first guiding structure 14, respectively. Even if the battery 30 and the mechanism body 10 are placed outside the agricultural drone, sufficient stability can be maintained between the battery 30 and the agricultural drone, thereby ensuring a good electrical connection between the battery 30 and the agricultural drone and providing stable power to the agricultural drone.

[0083] Please continue to refer to the appendix. Figures 1-5 As an optional embodiment of the first guide structure 14, the first guide structure 14 is a guide rib. The guide rib protrudes from the groove wall of the expansion groove 11 and extends in the direction close to and away from the groove opening. The battery 30 can cooperate with the guide rib during the process of entering and exiting the expansion groove 11 through the groove opening. The guide rib can correctly guide the battery 30 through the groove opening to the mounting position in the expansion groove 11 and to detach from the expansion groove 11. The battery 30 can be inserted and removed from the socket in the expansion groove 11 in the correct direction, reducing the risk of damage to the battery socket and the socket in the expansion groove 11.

[0084] In the embodiments described above, the guide ribs can protrude from the groove wall within the expansion groove 11. The specific position and number of these guide ribs can be determined according to the standardized battery 30 structure corresponding to the modular battery 30 mounting mechanism. For example, if guide grooves are provided on both opposite sides of the battery 30, guide ribs will protrude from the opposite side groove walls within the expansion groove 11. Conversely, if a guide groove is provided on only one side of the battery 30, guide ribs will protrude from the side groove wall within that guide groove.

[0085] Of course, in other embodiments, if the surface structure of the standardized battery 30 is set as a rib with a guiding function, the first guiding structure 14 provided in the expansion groove 11 should be set as a guiding groove adapted to the rib structure. However, given the wide variety of components and structures with guiding functions in the relevant field, this embodiment will not be described in detail here.

[0086] Please refer to the appendix. Figures 11-12The images show the front and side views of the battery 30 provided in this embodiment. The standardized structure battery 30 has an overall structure that is roughly cuboid. The battery 30 includes two opposing first side portions 31, a bottom side portion 32 connected to the lower part of the two first side portions 31, and a top side portion 34 connected to the upper part of the two first side portions 31. The bottom side portion 32 and the top side portion 34 are also arranged opposite to each other. The battery 30 also includes a front side portion 33 located at one end of the first side portion 31, the bottom side portion 32, and the top side portion 34, and a rear side portion 35 located at the other end of the first side portion 31, the bottom side portion 32, and the top side portion 34. The battery 30 has guide grooves on the two opposing first side portions 31 that are adapted to the guide rib structure. That is, the guide ribs are provided on any two opposing groove walls of the expansion groove 11 in the expansion groove 11. In this embodiment, the guide ribs are provided on the opposite two groove walls of the expansion groove 11 in the vertical direction.

[0087] Please continue to refer to the appendix. Figure 1 Taking the first guide structure 14 as an example of a guide rib protruding from the wall of the expansion groove 11, the surface of the guide rib is formed with a first guide surface 141 and a second guide surface 142 connected along its extension direction. The first guide surface 141 is set close to the groove opening, and the second guide surface 142 is set away from the groove opening.

[0088] For example, the guide rib is provided on the wall of the expansion groove 11 with a first segment and a second segment arranged sequentially along its extension direction. The first guide surface 141 is formed on the side of the first segment away from the wall of the expansion groove 11, and the second guide surface 142 is formed on the side of the second segment away from the wall of the expansion groove 11. The distance between the first guide surface 141 and the wall of the expansion groove 11 corresponding to it is smaller than the distance between the second guide surface 142 and the wall of the expansion groove 11 corresponding to it, so that there is a step difference between the first guide surface 141 and the second guide surface 142. The first guide surface 141, which is closer to the wall of the expansion groove 11, can provide more room for the installation and removal of the battery 30. This makes it easier for the battery 30 to form a guiding engagement with the first segment of the guide rib when it first enters the expansion groove 11, reducing the installation difficulty of the battery 30 and the mechanism body 10, and also making it easier for the battery 30 to detach from the expansion groove 11. As the battery 30 slides from the first section of the guide rib to the second section, the guide groove on the battery 30 will contact the transition surface 143 between the first guide surface 141 and the second guide surface 142, thereby guiding the battery 30 to the first section to form a guiding engagement state. Through the engagement with the first section of the guide rib, the battery 30 can be more stable when mounted in the expansion groove 11.

[0089] The aforementioned transition surface 143 is mainly used to guide the battery 30 more smoothly to a state that matches the second section of the guide rib, reducing interference when the guide groove on the battery 30 transitions from the first section to the second section. Here, the transition surface 143 can be an inclined surface that is tilted relative to the first guide surface 141 and the second guide surface 142, or an arc surface that connects the first guide surface 141 and the second guide surface 142 at both ends.

[0090] Of course, in some implementations, the first segment of the guide rib can also achieve a similar purpose to providing more space for the battery 30 by narrowing its width dimension.

[0091] Based on any of the above embodiments, as one specific structural form of the mechanism body 10, it can correspond to the specific structure of a standardized battery product, such as... Figure 1 As shown, the mechanism body 10 includes two side plates 15 arranged opposite to each other and spaced apart, and an end plate 16 connected between the two side plates 15. A mounting space for accommodating the battery 30 is formed between the side plates 15 and the end plate 16. The size of the mounting space determines the number of batteries 30 that the mechanism body 10 can accommodate. In order to maintain the relative stability of the state of each battery 30 mounted in the mechanism body 10, a partition 17 is provided between the two side plates 15. In an embodiment where the mechanism body 10 is provided with more than two expansion slots 11, the mechanism body 10 can be provided with a corresponding number of partitions 17 according to the number of expansion slots 11 it has. The two side plates 15, the end plate 16 and the partitions 17 cooperate to define two expansion slots 11. The slot opening is formed at the end of the expansion slot 11 away from the end plate 16. The first fixing structure 12 is provided on one of the side plates 15.

[0092] For example, when a partition 17 is provided between the two side plates 15 of the mechanism body 10, the mechanism body 10 is provided with two expansion slots 11, and these two expansion slots 11 are respectively formed on opposite sides of the partition 17; when the mechanism body 10 is located between the two side plates 15 and two partitions 17 are provided, the two partitions 17 are spaced apart from each other, and the mechanism body 10 is provided with three expansion slots 11, one of which is formed between the two partitions 17, and the other two expansion slots 11 are respectively formed on the side of the two partitions 17 that are far apart from each other, and so on.

[0093] As mentioned above, the socket located in the expansion slot 11 can be installed on the partition 17, the first fixing structure 12 is installed on the outer side wall of one of the side panels 15, and the first limiting structure 13 is also installed on the outer side wall of the side panel 15 where the first fixing structure 12 is installed, and the first guiding structure 14 is installed on the inner side wall of at least one side panel 15.

[0094] In one embodiment, please continue to refer to the appendix. Figure 1Taking the embodiment where the main body 10 is provided with only two expansion slots 11 as an example, the two sides of the main body 10 are open structures, that is, the expansion slots 11 located on the opposite side of the partition 17 do not have corresponding shielding structures. When the battery 30 is assembled in the expansion slots 11, one side of the partition 17 will be exposed outside the main body 10. In some embodiments, part of the battery 30 structure will protrude outside the main body 10 through this normally open structure. The purpose of this design is mainly to save the consumables of the main body 10 and to make the structure of the main body 10 compatible with the structure of the corresponding agricultural drone. For example, when applied to agricultural drones, the mobile platform structure of agricultural drones is relatively small compared to other unmanned devices. Therefore, the structure of the main body 10 is also reduced accordingly according to the mobile platform of the drone to ensure that the first limiting structure 13 and the first fixing structure 12 on the main body 10 can be adapted to the second limiting structure 212 and the second fixing structure 211 on the drone. In addition, this setting is also conducive to the heat dissipation of the battery 30 in the use state of the agricultural drone and improves its power supply performance.

[0095] According to the above structure, the limiting ribs of the first guide structure 14 can be respectively set on the side of the two expansion slots 11 that are far apart from each other, while the first fixing structure 12 can be respectively placed on the opposite sides of the side plate 15, and the first limiting structure 13 can be set between the two first fixing structures 12.

[0096] Please continue to refer to the appendix. Figures 1-10 This invention also provides an agricultural drone employing the aforementioned modular battery loading mechanism. It should be noted that the agricultural drone described in this embodiment is suitable for movement in aerial environments, such as fixed-wing aircraft, rotary-wing aircraft, or aircraft without fixed wings or rotors. Specifically, the agricultural drone in this embodiment is an unmanned aerial vehicle (UAV). The UAV can be a multi-rotor UAV, such as a quadcopter, hexacopter, octacopter, or dodecacopter UAV. The UAV can be used to carry payloads to complete predetermined tasks, such as carrying imaging devices for photography, carrying pesticides, nutrient solutions, and spraying devices for plant protection tasks, and can also be used in other fields such as geographic surveying, aerial photography, power line inspection, environmental monitoring, and disaster relief.

[0097] It is understood that the agricultural drone described in this embodiment includes a main body 20 (equivalent to the fuselage of the agricultural drone mentioned above). Generally, the main body 20 is also provided with arms 23 for supporting the power components and landing gear 24 for the main body 20. For example, taking a rotorcraft drone as the subject of this description, the number of power components corresponds to the number of rotor components. The power components are distributed around the outer periphery of the main body 20 by the support of the arms 23, and each power component is used to individually control and drive the rotation of the corresponding rotor. The number of power components can be appropriately varied according to different needs. For example, the number of power components can be two, three, four, six, etc., or even only one. Correspondingly, the number of arms 23 can also be reasonably set according to the number of power components.

[0098] The device body 20 described above has a loading section 21 on its upper part. The loading section 21 is used to provide a corresponding loading position for the modular battery loading mechanism as described in any of the above embodiments. That is, the upper space of the device body 20 serves as the loading space for the modular battery loading mechanism, so as to expand the battery mounting space.

[0099] The device body 20 is detachably mounted on its loading section 21 with at least one modular battery loading mechanism as described above. The main body 10 of the modular battery loading mechanism can be fixedly mounted on the top of the agricultural drone through the first fixing structure 12. By utilizing the relatively extra space on the top of the agricultural drone, the agricultural drone can provide a larger loading position for the main body 10. The agricultural drone can carry different numbers of main bodies 10 according to different situations, thereby improving the expandability of the number of batteries 30 and broadening the application scenarios of the product.

[0100] It should be noted that, in some embodiments, due to the limitations of the structural form of the plant protection drone's main body 20, when there are at least two modular battery loading mechanisms, the mechanism body 10 is at least partially disposed on the loading part 21 along the width direction of the main body 20. By utilizing the space of the main body 20 in its width direction (the "left" and "right" directions indicated by the arrows in the accompanying drawings), a stable cooperation relationship is maintained between the mechanism body 10 and the main body 20, and the problem of center of gravity shift of the main body 10 and the battery 30 mounted on the mechanism body 10 on the main body 20 is reduced to a certain extent.

[0101] Through the above technical solution, the agricultural drone can be equipped with a corresponding number of mechanism bodies 10 and the number of batteries 30 required on each mechanism body 10 according to the endurance requirements of the task it is currently performing. For example, when the area of ​​the work site is relatively small and / or the required material density is low, the endurance requirement of the agricultural drone also decreases. In this case, the loading unit 21 can be equipped with one mechanism body 10, and the mechanism body 10 can be equipped with one or more batteries 30 according to actual needs. When the area of ​​the work site is relatively large and / or the required material density is large, the endurance requirement of the agricultural drone also increases. In this case, the loading unit 21 can be equipped with two or at least two mechanism bodies 10 to provide more battery mounting space, and the mechanism body 10 can also be equipped with one or more batteries 30 according to actual needs.

[0102] It is worth mentioning that when the agricultural drone is equipped with the corresponding number of batteries 30, the batteries 30 should be kept as balanced as possible on the main body 20. However, in reality, the batteries 30 will inevitably affect the center of gravity of the main body 20, causing a certain degree of shift in the center of gravity. In this case, the ratio of the weight of the batteries 30 to the weight of the main body 20 should be considered to minimize the impact of the batteries 30 on the center of gravity of the main body 20. For example, the weight of a single battery 30 should be controlled at 5-7 kg, while the weight of the main body 20 should be controlled at 70-120 kg. Therefore, the weight of the battery 30 is relatively small compared to the weight of the device body 20, and the battery 30 is mainly installed near the geometric center of the device body 20 to minimize the impact. The center of gravity offset problem that still exists in the device body 20 can be compensated by the software algorithm of the control unit of the device body 20. By using different power outputs of the power components on different sides, the balance of the device body 20 during operation can be ensured. Therefore, during the balanced operation of the device body 20, each power component should ensure that there is still a certain power margin to compensate for the center of gravity offset problem of the device body 20.

[0103] Of course, based on the above description of the modular battery loading mechanism, it can be understood that in other embodiments of the agricultural drone, and when there are at least two modular battery loading mechanisms, the mechanism body 10 can also be arranged in other directions such as the front-back direction, the up-down direction, etc. of the device body 20. However, it should be noted that in embodiments where the agricultural drone is an unmanned aerial vehicle, since the head of the device body 20 needs to be equipped with functional components such as flight control and radar, the mechanism body 10 is not suitable to be arranged in the front-back direction of the device body 20. In the method of arranging the mechanism body 10 in the up-down direction, the design difficulty and cost of the highly stacked structure are higher than that of the parallel arrangement, and it is not conducive to the stable control of the center of gravity of the device body 20. Therefore, the more suitable arrangement is to arrange the mechanism body 10 in the width direction of the device body 20.

[0104] As can be seen from the above technical solutions, the number of mechanical bodies 10 loaded on the loading section 21 of the equipment body 20 can be two, three, four or even more. However, in the application of unmanned aerial vehicles, considering the current general operating environment, load capacity and endurance requirements of unmanned aerial vehicles, this embodiment takes the embodiment in which the loading section 21 can be loaded on a maximum of two mechanical bodies 10 as an example.

[0105] Based on the above-mentioned limitations on each direction, it can be understood that the front and rear directions of the equipment body 20 located on the loading section 21 (the "front" and "rear" directions indicated by the arrows in the attached figure can also be understood as the front-rear direction) are perpendicular to its width direction (the "left" and "right" directions indicated by the arrows in the attached figure can also be understood as the left-right direction). Taking the loading position as a relatively flat loading surface as an example, the closing direction of the equipment body 20 and its width direction are both located on the loading surface and are perpendicular to each other.

[0106] Based on the above, the length direction of the expansion slot 11 is consistent with the head-to-tail direction of the device body 20, and the width direction of the expansion slot 11 is perpendicular to both the head-to-tail direction and the width direction of the device body 20. That is, the width direction of the expansion slot 11 is different from the width direction of the mechanism body 10 and the device body 20. (See attached diagram.) Figures 1-10Understandably, this design allows the battery 30, when inserted into the expansion slot 11, to maintain a parallel longitudinal direction to the drone's bow and stern. This ensures the battery 30's weight is evenly distributed across the device body 20, minimizing its impact on the device's center of gravity. Considering the aforementioned structural limitations of the battery 30, in this embodiment, the width of the battery 30 is the distance between its top side 34 and bottom side 32, and the thickness (height) of the battery 30 is the distance between its two opposite first sides 31. The length of the battery 30 is the distance between the front side 33 and the rear side 35 of the battery 30. Since the width of the battery 30 is greater than its thickness (height), in this embodiment, the width direction of the expansion slot 11 is set to be perpendicular to the head-to-tail direction and the width direction of the device body 20. This allows the thickness (height) direction of the battery 30 to be consistent with the width direction of the device body 20 when the battery 30 is housed in the expansion slot 11. This makes the size of the battery 30 in the width direction of the device body 20 relatively small, reducing the occupancy of the loading position and thus providing corresponding loading positions for a larger number of batteries 30.

[0107] In one embodiment, the slots on the mechanism body 10 that connect to the expansion slot 11 are all set to face the tail of the device body 20. Taking the agricultural drone as an example of an unmanned aerial vehicle, this setting can reduce or even avoid interference between the battery 30 and the mechanism body 10 during disassembly and assembly, and between the flight control and radar set at the head of the device body 20, as well as the material box and other components set in the width direction of the device body 20.

[0108] Corresponding to the specific structure of the modular battery loading mechanism, such as Figures 1-10 As shown, the loading part 21 is provided with a second fixing structure 211, which is adapted to the first fixing structure 12. The mechanism body 10 can be fixedly installed on the equipment body 20 through the first fixing structure 12 and the second fixing structure 211.

[0109] In some embodiments, the agricultural drone has a pre-installed fixing structure on its upper part for mounting external functional components. Thus, the design of the first fixing structure 12 on the main body 10 can be determined based on the second fixing structure 211 pre-installed on its loading section 21 during the manufacturing process of the main body 20. Based on the above exemplary description of the first fixing structure 12, several specific structures of the second fixing structure 211 are listed below:

[0110] For example, when the first fixing structure 12 and the second fixing structure 211 are combined into a snap-fit ​​structure, the first fixing structure 12 and the second fixing structure 211 can be respectively set as a matching snap-fit ​​and a corresponding slot.

[0111] When the first fixing structure 12 and the second fixing structure 211 are combined into a mortise and tenon structure, the first fixing structure 12 and the second fixing structure 211 can be respectively set as a matching tenon and mortise.

[0112] When the first fixing structure 12 and the second fixing structure 211 are combined into a screwed structure, the first fixing structure 12 and the second fixing structure 211 can be respectively configured as a positioning hole and a threaded hole, so that the two can be fixed by means of external bolts being positioned through the positioning hole and screwed into the threaded hole.

[0113] As can be understood from the above exemplary description, the first fixing structure 12 and the second fixing structure 211 can be installed either by direct connection or by indirect connection.

[0114] In this embodiment, the first fixing structure 12 and the second fixing structure 211 are installed using the above-mentioned screw connection structure as an example of a specific assembly method between the mechanism body 10 and the equipment body 20. Using the screw connection structure as the fixing structure between the mechanism body 10 and the equipment body 20 can save processing costs more effectively compared with other commonly used fixing structures in related fields. In addition, the space occupied by the screw connection structure is smaller than that of other fixing structures, and the assembly strength is higher, which can effectively ensure the overall structural stability of the agricultural drone during the operation.

[0115] Please refer to the appendix. Figures 1-10 Specifically, the first fixing structure 12 consists of positioning holes distributed on opposite sides of the bottom of the mechanism body 10. Based on the above definitions of the mechanism body 10 and the equipment body 20 in various directions, when the first fixing structure 12 is distributed on opposite sides of the width direction of the mechanism body 10, the mechanism body 10 has multiple positioning holes spaced apart along its length direction on both sides. When the first positioning structure is distributed on opposite sides of the length direction of the mechanism body 10, the mechanism body 10 has multiple positioning holes spaced apart along its width direction on both sides. The positioning holes are arranged through the mechanism body 10 in the vertical direction.

[0116] Correspondingly, the second fixing structure 211 is a threaded hole opened in the loading part 21 corresponding to each positioning hole position. In this embodiment, since the mechanism body 10 is set on the upper part of the equipment body 20, the positioning hole is set on the mechanism body 10, and the threaded hole is opened on the loading part 21, so that the bolt can be screwed into the threaded hole by passing through the positioning hole from the upper part of the mechanism body 10. The bolt head is used to press the mechanism body 10 against the loading part 21. Compared with the method of opening the positioning hole in the loading part 21 and the threaded hole in the mechanism body 10 (the bolt needs to be assembled from bottom to top), the assembly difficulty is lower, and it is convenient to disassemble and assemble the mechanism body 10 and adjust the number.

[0117] Please refer to the attached document. Figures 1-10 In addition to the first limiting structure 13 at the bottom of the above-mentioned mechanism body 10, the loading part 21 is provided with a second limiting structure 212 that is adapted to the first limiting structure 13 at the position corresponding to the first limiting structure 13.

[0118] Similarly, in some embodiments, the second limiting structure 212 can also be a limiting structure reserved on the loading part 21 where the equipment body 20 is located during its processing, so as to save the cost of secondary processing or redesign of the equipment body 20 by adapting the first limiting structure 13 to the second limiting structure 212. Based on the above exemplary description of the first limiting structure 13, the following are some specific structures of the second limiting structure 212:

[0119] For example, when the first fixing structure 12 and the second fixing structure 211 are combined into a guide slider and a slide rail structure, the first fixing structure 12 and the second fixing structure 211 can be respectively set as a compatible guide slider and a corresponding slide rail.

[0120] When the first fixing structure 12 and the second fixing structure 211 are combined into a snap-fit ​​structure, the first fixing structure 12 and the second fixing structure 211 can be respectively configured as a compatible snap-fit ​​and a slot.

[0121] It is understandable that the limiting structure should be a cooperative structure with a relatively simple and quick disassembly and assembly method and a strong pre-positioning function, so as to ensure that the mechanism body 10 and the equipment body 20 can achieve rapid positioning and mutual limiting in some degrees of freedom of movement by relying on the first limiting structure 13 and the second limiting structure 212.

[0122] Please continue to refer to the appendix. Figures 1-10The first limiting structure 13 consists of at least two parallel limiting ribs, which are spaced apart along the width direction of the expansion groove 11 and extend along the length direction of the expansion groove 11. Correspondingly, the second limiting structure 212 is a limiting groove formed on the loading part 21. The opposite side walls of the limiting groove extend along the head and tail direction of the equipment body 20. As can be seen from the above description of the embodiment, the limiting groove on the loading part 21 can be a groove structure reserved by the equipment body 20 during the processing according to the requirements of other functional components and structural characteristics. The mechanism body 10 is then processed with corresponding limiting ribs at the bottom of the mechanism body 10 according to the limiting groove structure reserved on the equipment body 20.

[0123] When the mechanism body 10 is mounted on the loading part 21, the side walls of the two limiting ribs that are opposite to each other are respectively relative to the two opposite groove walls of the limiting groove. Furthermore, the corresponding limiting ribs are fitted with the groove walls of the limiting grooves with a clearance, so that while the mechanism body 10 achieves mutual limiting with the equipment body 20 in the width direction through the first limiting structure 13 and the second limiting structure 212, the mechanism body 10 and the equipment body 20 retain the degree of freedom of movement in the vertical direction and even the front-back direction, which facilitates further adjustment of the relative position of the mechanism body 10 and the equipment body 20.

[0124] Specifically, when the mechanism body 10 and the equipment body 20 have completed the pre-positioning engagement, the mechanism body 10 is supported on the surface of the loading part 21 by its lower part, while the two limiting ribs located at the bottom of the equipment body 20 are engaged in the limiting grooves on the loading part 21. Subsequently, the mechanism body 10 and the equipment body 20 can be further installed and engaged through the positioning holes opened on opposite sides of the equipment body 20 and the threaded holes opened on the loading part 21.

[0125] According to the above structure, in one embodiment, such as Figures 6-10 As shown, when two mechanism bodies 10 are provided on the equipment body 20, the two mechanism bodies 10 are arranged side by side on the loading part 21 along the width direction of the equipment body 20. The two mechanism bodies 10 can respectively form a limiting fit with the groove walls on opposite sides of the limiting groove through the limiting protrusions located on the side close to each other, so as to improve the alignment accuracy between each mechanism body 10 and the equipment body 20 when assembling two or more mechanism bodies 10. At the same time, the two mechanism bodies 10 can also be installed and fixed to the second fixing structures 211 located on opposite sides of the loading part 21 of the equipment body 20 through the first fixing structure 12 on the side close to each other.

[0126] Based on the above-mentioned arrangement of the mechanism body 10 on the device body 20, when there are at least two modular battery loading mechanisms, the mechanism body 10 is arranged sequentially on the loading part 21 along the width direction of the device body 20 to maximize the use of the mounting space in the width direction above the device body 20.

[0127] Furthermore, in the embodiment that coordinates with the above-mentioned arrangement of the battery 30 in the expansion slot 11, the battery mounting space can be increased to a greater extent, allowing the agricultural drone to carry more batteries 30 within a limited space.

[0128] Please refer to the attached document. Figures 6-10 In order to improve the assembly stability between the mechanism body 10 and the equipment body 20 when there are at least two modular battery loading mechanisms, an extension mounting member 22 is provided on at least one side of the equipment body 20. The upper part of the extension mounting member 22 forms a support surface 221 that connects with the loading part 21 to expand the space of the loading part 21 and increase the position for loading the mechanism body 10.

[0129] In the embodiment where the extension mounting member 22 is provided in conjunction with the device body 20, a part of the mechanism body 10 is installed on the device body 20 via the loading part 21, and another part of the mechanism body 10 is placed on the support surface 221. The extension mounting member 22 is fixedly connected to the device body 20 so that when it supports the mechanism body 10 via the support surface 221, the weight of the part of the mechanism body 10 not directly supported by the loading part 21 of the device body 20 can be transferred to the device body 20 through the extension mounting member 22. This prevents the mechanism body 10 from being suspended on one side of the device body 20, avoids the torque generated by the cantilever structure from causing the connection failure between the first fixed structure 12 and the second fixed structure 211, and achieves the purpose of stable installation of the mechanism body 10 and the device body 20.

[0130] Of course, in some embodiments, the extension mounting component 22 located on the support surface 221 can also achieve the effect of fixed connection between the extension mounting component 22 and the mechanism body 10 by setting a third fixing structure that is compatible with the first fixing structure 12.

[0131] In one embodiment, the extension mounting component 22 is provided with a third limiting structure 222 on the side of the support surface 221 away from the device body 20. When the mechanism body 10 is placed on the support surface 221, the extension mounting component 22 is limited and cooperates with the mechanism body 10 through the third limiting structure 222.

[0132] Please refer to the attached document. Figures 6-10The third limiting structure 222 can be set according to the adaptability of the bottom structure of the mechanism body 10. The third limiting structure 222 can restrict the degree of freedom of movement of the mechanism body 10 in the part not directly supported by the loading part 21, so as to further improve the assembly strength between the mechanism body 10 and the equipment body 20.

[0133] In this example, the third limiting structure 222 is a limiting block protruding on one side of the supporting surface 221. The limiting block can be stopped by abutting against the outer side of the mechanism body 10 or by opening a corresponding limiting groove at the bottom of the mechanism body 10.

[0134] It is worth mentioning that, since the extension mounting component 22 is located on one side of the width direction of the equipment body 20, the extension mounting component 22 will form a cantilever structure to a certain extent on the equipment body. In order to prevent the extension mounting component 22 from being deformed by the weight of the mechanism body 10 when it supports the mechanism body 10 through the support surface 221, multiple mutually spaced reinforcing ribs 223 can be provided between the support surface 221 and the side of the equipment body 20 to improve the structural strength of the extension mounting component 22.

[0135] In summary, this embodiment utilizes the mounting space provided on the upper part of the agricultural drone to increase the number of batteries 30 that can be mounted on the agricultural drone, such as... Figures 2-5 As shown, in this embodiment, when there is only one mechanism body 10, the device body 20 can carry one or two batteries 30, such as... Figures 6-10 As shown, when there are two main body 10s, the main body 20 can be equipped with three or four batteries 30 to suit different task conditions, improve the task execution efficiency of agricultural drones, broaden the application scenarios of the equipment, meet the needs of different users, and enable agricultural drones to achieve different purposes.
