[0034] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0035] Drones are already widely used in agriculture. Agricultural drones can be equipped with various operating systems for spraying and sowing. Currently, when using agricultural drones for seeding, the seeding device is typically mounted on the drone's fuselage, allowing it to follow the drone's flight and perform the seeding operation. 。

[0036] Agricultural drones in related technologies suffer from technical problems such as inconvenient feeding due to limitations in their airframe structure, frequent feeding operations, and low work efficiency.

[0037] Please refer to Figures 1-3This embodiment provides an agricultural drone 100. It can enlarge the opening of the feed inlet 41 of the storage box 40, thereby facilitating feeding, reducing the number of feeding operations, and improving work efficiency.

[0038] In this embodiment, the carrier is a drone, specifically an agricultural drone, which is generally equipped with spraying components, seeding components, etc. required for agriculture, and can realize spraying irrigation, seeding, etc.

[0039] In this embodiment, the agricultural drone 100 includes a main frame 10, multiple arms 20, and a storage box 40. The main frame 10 is longer in the front-to-back direction than in the left-to-right direction. One end of each arm 20 is connected to a corner of the main frame 10, and the other end of each arm 20 is connected to a power unit 30. The storage box 40 is used to load materials. The inlet 41 of the storage box 40 is located on the left and / or right side of the main frame 10 and is close to the main frame 10.

[0040] In this embodiment, the material in the storage tank 40 can be a solid material or a liquid material, and no specific limitation is made here.

[0041] It should be noted that the front-to-back direction of the main frame 10 is the forward and backward direction of the UAV's flight, and the left-to-right direction of the main frame 10 is the direction perpendicular to the front-to-back direction and parallel to the horizontal plane.

[0042] It should also be noted that, in this embodiment, "close" means that the distance between the surfaces of the main frame 10 and the storage box 40 that are close to each other is small. With this setting, the feed inlet 41 can be as large as possible while keeping the size of the storage box 40 unchanged.

[0043] In this embodiment, the number of robotic arms 20 is four. In other embodiments, the number of robotic arms 20 may be increased or decreased, and no specific limitation is made here.

[0044] Specifically, the main frame 10 of the machine body is connected to two arms 20 on both sides in the left and right directions, and the two arms 20 are set at an angle to each other.

[0045] It should also be noted that the airframe structure of existing drones is generally horizontally developed, that is, developed along the left-right direction as shown in this embodiment. Therefore, the airframe structure of existing drones is relatively long in the left-right direction, with less usable space, and relatively narrow in the front-back direction. The feed inlet of the storage box can be set in the left-right direction, but due to the limited usable space in the left-right direction of the airframe structure, the opening area of ​​the feed inlet of the storage box will be limited, and the space of the feed inlet will be relatively cramped. In actual use, the number of times to add materials will be more frequent, making material addition inconvenient and reducing work efficiency. To address this technical problem, the agricultural drone 100 provided in this embodiment has its arm 20 connected to the main frame 10 and its power unit 30 during use. The power unit 30 provides power to achieve flight. The main frame 10 is longer in the front-to-back direction than in the left-to-right direction, which increases the length of the main frame 10 in the front-to-back direction and increases the space on the left and right sides of the drone. Since the feed inlet 41 of the storage box 40 is located on the left and / or right side of the main frame 10, while increasing the space on the left and right sides of the main frame 10, the feed inlet 41 is close to the main frame 10, which increases the opening area of ​​the feed inlet 41 of the storage box 40, making feeding more convenient, reducing the number of feedings, and improving work efficiency.

[0046] In this embodiment, there are two feed inlets 41, which are respectively located on both sides of the main frame 10 in the left-right direction, and are located between two adjacent machine arms 20. In other embodiments, the feed inlets 41 may be located only on the left side of the main frame 10, or only on the right side of the main frame 10, and no specific limitation is made here.

[0047] The feed inlet 41 has a square structure. The width of the feed inlet 41 is parallel to the front-back direction of the main frame 10 of the machine body, and the length of the feed inlet 41 is parallel to the left-right direction of the main frame 10 of the machine body. Since the length of the main frame 10 of the machine body in the front-back direction is greater than its length in the left-right direction, the length of the feed inlet 41 is also lengthened, thereby increasing the opening area of ​​the feed inlet 41.

[0048] Specifically, the feed inlet 41 has a chamfer at its corner, which is close to the outer surface of the machine arm 20, and the shape of the chamfer is adapted to the shape of the machine arm 20.

[0049] It should also be noted that the main frame 10 of the machine body includes two main beams 11 and two connecting blocks 12. The two connecting blocks 12 are respectively set at both ends of the main beams 11. The two main beams 11 are parallel to the front-back direction of the main frame 10 of the machine body, and the two connecting blocks 12 are parallel to the left-right direction of the main frame 10 of the machine body. The two main beams 11 and the two connecting blocks 12 together form a square frame structure. Both ends of the connecting blocks 12 are connected to the arms 20. The shape of the feed port 41 is adapted to the shape of the main beams 11 and the shape of the arms 20.

[0050] In this embodiment, the connecting block 12 is made of plastic material, and the main beam 11 is made of metal material.

[0051] Specifically, the existing airframe structure has a large width in the left-right direction, which results in a large frontal area and greater drag when the drone is flying at high speed, which is not conducive to optimizing overall efficiency. In order to solve this technical problem, in this embodiment, the length of the main beam 11 of the main frame 10 is longer than the length of the connecting block 12, thereby lengthening the whole machine in the longitudinal direction, i.e., the front-back direction, reducing the overall width in the lateral direction, thereby reducing the frontal area, reducing drag, and improving overall efficiency.

[0052] It should also be noted that the agricultural drone 100 also includes a battery 50. The main frame 10 has a central battery compartment inside, where the battery 50 is located and connected to the main beam 11.

[0053] Specifically, in existing technologies, batteries are generally placed at the rear of the drone, making it difficult to adjust the overall center of gravity to the geometric center point, thus limiting the arrangement of the load center of gravity. To solve this technical problem, the battery 50 provided in this embodiment is placed in the central battery compartment of the main frame 10, so that the center of gravity of the entire drone is at the geometric center of the drone, avoiding the problem of difficulty in adjusting the overall center of gravity, making the overall structure more stable and the flight controllability higher. At the same time, using the main frame 10 as a support for the battery 50 can effectively protect the battery 50.

[0054] In addition, the storage tank 40 is located below the main frame 10 of the machine body, and the feed inlet 41 of the storage tank 40 is close to the main frame 10 of the machine body when viewed from above. The feed inlet 41 is located above the discharge outlet. After the material enters the storage tank 40 through the feed inlet 41, it can reach the discharge outlet under the action of gravity.

[0055] Furthermore, the agricultural drone 100 also includes a spreading mechanism connected to the discharge port of the storage tank 40 for spreading solid materials from the storage tank 40 to the outside of the drone. In other embodiments, the agricultural drone 100 also includes a spraying mechanism connected to the discharge port of the storage tank 40 for spraying liquid materials from the storage tank to the outside of the drone. Of course, the mechanisms mounted on the agricultural drone 100 are not limited to spreading or spraying mechanisms, and no specific limitation is made here.

[0056] It should also be noted that the agricultural drone 100 includes a nose module 60 and a load device. The nose module 60 is located outside the main frame 10 and connected to it. Specifically, the load device is suspended on the main beam 11, and the nose module 60 is connected to the connecting block 12. This allows full use of the metal strength of the main beam 11 to carry more load, making the overall structure more compact, the flight more stable, and cost-effective.

[0057] In this embodiment, the robotic arm 20 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 and the second connecting rod 22 are rotatably connected. The end of the first connecting rod 21 away from the second connecting rod 22 is connected to the corner of the main frame 10 of the machine body. The end of the second connecting rod 22 away from the first connecting rod 21 is connected to the power device 30. The second connecting rod 22 rotates about the end connected to the first connecting rod 21 to lengthen or shorten the robotic arm 20.

[0058] Furthermore, the agricultural drone 100 also includes a tripod 70, which is located at the bottom of the main frame 10 and covers the outside of the storage box 40.

[0059] In summary, the present invention provides an agricultural drone 100, which includes a main frame 10, multiple arms 20, and a storage box 40. The main frame 10 is longer in the front-to-back direction than in the left-to-right direction. One end of each arm 20 is connected to a corner of the main frame 10, and the other end of each arm 20 is connected to a power unit 30. The storage box 40 is used to load materials, and the inlet 41 of the storage box 40 is located on the left and / or right side of the main frame 10 and is close to the main frame 10. When in use, the agricultural drone 100 has its arm 20 connected to the main frame 10, and the arm 20 connected to the power unit 30. The power unit 30 provides power to achieve flight. The main frame 10 is longer in the front-to-back direction than in the left-to-right direction, which can lengthen the main frame 10 in the front-to-back direction and increase the space on the left and right sides of the drone. Since the feed inlet 41 of the storage box 40 is located on the left and / or right side of the main frame 10, while increasing the space on the left and right sides of the main frame 10, the feed inlet 41 is close to the main frame 10, which can increase the opening area of ​​the feed inlet 41 of the storage box 40, making feeding more convenient, reducing the number of feedings, and improving work efficiency.

[0060] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
