Description

Technical Field

[0001] This utility model relates to a feeding and spreading drone, belonging to the field of agricultural planting technology. Background Technology

[0002] A seeding drone is a type of unmanned aerial vehicle (UAV) used in agriculture, forestry, or other fields for the precise dissemination of materials such as seeds, fertilizers, and pesticides. Combining UAV technology with an intelligent control system, it can efficiently and accurately complete large-area dissemination operations, suitable for complex terrain or areas difficult to reach manually. Through GPS or RTK positioning systems, it achieves high-precision flight path planning and uniform material dissemination, reducing waste. A single flight can cover tens or even hundreds of acres of land, significantly improving operational efficiency. It supports functions such as preset flight paths, automatic obstacle avoidance, and real-time monitoring, reducing operational complexity.

[0003] A seeding drone is a type of drone used for seeding. The seeder carries a seeder that can store seeds for seeding operations. Because the drone carries the seeder and seeds, the large gravity during takeoff and landing may cause impact on the drone, affecting its service life. In addition, the installed seeder is not easy to secure effectively. It is not easy to disassemble and assemble quickly, and it is also easy to fall off during the seeding process, reducing the performance of the drone. Utility Model Content

[0004] This invention provides a material-feeding and spreading drone to solve the technical problems of poor buffering effect and inconsistency in seeder installation of drones.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a material delivery and spreading drone, comprising:

[0007] The fuselage has landing gear rotatably connected to both sides of its bottom. The landing gear is connected to a buffer mechanism via movable joints. The buffer mechanism is located between the two landing gears. A cross plate is fixedly connected to the bottom of the fuselage. A spreader is provided at the bottom of the cross plate. A hook is fixedly connected to the top of the spreader and is hooked to the cross plate.

[0008] In this technical solution, the body is rotatably connected to swing arms on all four sides, and each swing arm is equipped with a flying wing at its distal end.

[0009] In this technical solution, the landing gear has a U-shaped structure, and the landing gear is symmetrically arranged on both sides of the spreader. The length of the spreader is less than the length of the landing gear.

[0010] In this technical solution, the buffer mechanism consists of a sleeve and movable rods. Both ends of the sleeve are movably connected to the movable rods. The two movable rods are fixedly connected to both ends of the connecting spring, and the other ends of the two movable rods are rotatably connected to the movable joint.

[0011] In this technical solution, the bottom of the machine body is provided with two horizontal plates, both of which are L-shaped structures, and the crossbars are symmetrically arranged on both sides of the machine body.

[0028] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0029] like Figures 1-6 As shown, the feeding and spreading drone includes:

[0030] The fuselage 1 has landing gear 4 rotatably connected to both sides of its bottom. The landing gear 4 is connected to a buffer mechanism via a movable section 5. The buffer mechanism is located between the two landing gears 4. A horizontal plate 9 is fixedly connected to the bottom of the fuselage 1. A spreader 10 is provided at the bottom of the horizontal plate 9. A hook 11 is fixedly connected to the top of the spreader 10 and is hooked to the horizontal plate 9. A rod 15 is inserted through the side wall of the horizontal plate 9. The rod 15 is fixedly connected to the end of a crossbar 14 and the crossbar 14 is connected to a control mechanism below the fuselage 1.

[0031] The body 1 is rotatably connected to swing arms 2 on all four sides, and each swing arm 2 is equipped with a flying wing 3 at its far end; the landing gear 4 has a U-shaped structure and is symmetrically arranged on both sides of the spreader 10, and the length of the spreader 10 is less than the length of the landing gear 4; the buffer mechanism consists of a sleeve 8 and a movable rod 6, both ends of the sleeve 8 are movably connected to the movable rod 6, the two movable rods 6 are respectively fixedly connected to both ends of the connecting spring 7, and the other ends of the two movable rods 6 are rotatably connected to the movable section 5.

[0032] In this technical solution, the swing arm 2 can fold the flying wing 3 for easy storage. Before takeoff, the landing gear 4 supports the fuselage 1. When landing, the landing gear 4 touches the ground first. At this time, the landing gear 4 deflects slightly to both sides, which in turn pulls the movable rod 6 between the movable sections 5 to move. When the movable rod 6 moves stably inside the sleeve 8, the connecting spring 7 is stretched. The elasticity of the connecting spring 7 overcomes the deflection of the landing gear 4, thereby playing a buffering role during landing and avoiding damage to the fuselage 1 due to excessive impact force.

[0033] The bottom of the body 1 is provided with two horizontal plates 9, both of which are L-shaped. The horizontal bars 14 are symmetrically arranged on both sides of the body 1. The top of the spreader 10 is provided with hooks 11, each of which has an L-shaped cross section and is evenly arranged around the top of the spreader 10. A buffer pad 12 is fixedly connected to the top surface of the hook 11, and the buffer pad 12 is in close contact with the bottom surface of the body 1.

[0034] In this technical solution, when installing the spreader 10, the spreader 10 is pushed in from one side of the body 1, so that the spreader 10 passes through the landing gear 4 on one side, and the hook 11 is pushed flat onto the cross plate 9. At this time, the buffer pad 12 contacts the bottom surface of the body 1, thereby ensuring the stability of the spreader 10 after installation.

[0035] The control mechanism consists of a rotating shaft 16, which is rotatably connected to the bottom of the machine body 1. A winding wheel 17 is fixedly connected to the middle of the rotating shaft 16. A pull rope 18 is provided on the surface of the winding wheel 17, and one end of the pull rope 18 is fixedly connected to the crossbar 14. Two winding wheels 17 are provided in the middle of the rotating shaft 16, and the pull ropes 18 on the surfaces of the two winding wheels 17 are wound in opposite directions. Two symmetrically distributed insert rods 15 are provided on one side of the crossbar 14. The middle of the crossbar 14 is connected to the side wall of the cross plate 9 through a return spring 13. Each insert rod 15 extends into the interior of the cross plate 9, and the two insert rods 15 are respectively located between two hooks 11 on the same side.

[0036] In this technical solution, before pushing in the spreader 10, the handle at one end of the rotating shaft 16 is used to rotate the rotating shaft 16. When the rotating shaft 16 drives the winding wheel 17 to rotate synchronously, the winding wheel 17 winds up the pull rope 18. The pull rope 18 pulls the crossbar 14 and the insertion rod 15 to move synchronously, so that one end of the insertion rod 15 is separated from the inside of the horizontal plate 9. At this time, the spreader 10 is installed. After the installation is completed, the rotating shaft 16 is released. The return spring 13 in the stretched state pulls the crossbar 14 and the insertion rod 15 to return to their original positions. The insertion rod 15 moves between the two insertion rods 15 on the same side, limiting the insertion rod 15, thereby fixing the spreader 10. This facilitates quick installation. When disassembling, simply rotate the rotating shaft 16 and push out the spreader 10 to complete the disassembly, improving the ease of use.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
