Description

Technical Field

[0001] The present application relates to the field of agricultural drones, and more specifically, to an agricultural drone. Background Art

[0002] Agricultural plant protection drones, also known as agricultural unmanned aerial vehicles, are unmanned aircraft used for agricultural and forestry plant protection operations. This type of unmanned aircraft consists of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. Spraying operations are carried out through ground remote control or navigation flight control. It can spray pesticides, seeds, powders, etc.

[0003] Currently, agricultural drones are usually used for corresponding agricultural purposes by adding equipment to their bottom, and the bracket of traditional drones is installed to the bottom of the drone by bolts. When carrying the drone, the overall size of the bracket is large, and it is easy to accidentally hit the bracket and propeller. In addition, the impact force is large when landing during use, and the bracket is prone to excessive wear and damage. The connection method with multiple bolts is not convenient for disassembly and assembly. Utility Model Content

[0033] Among them, the elastic member 210 includes a groove shell 211, a fixed shaft 212 and a spring steel sheet 213. The groove shell 211 is fixedly connected to the bottom of the drone body 110, the fixed shaft 212 is arranged in the groove shell 211, the spring steel sheet 213 is arranged in the groove shell 211, and the end of the connecting plate 220 is rotatably sleeved on the surface of the fixed shaft 212 and abuts against the spring steel sheet 213. By setting the groove shell 211, the fixed shaft 212 and the spring steel sheet 213, the end of the connecting plate 220 is rotatably sleeved on the fixed shaft 212. During the landing process, the connecting plate 220 rotates and squeezes the spring steel sheet 213, and the spring steel sheet 213 is used for buffering to reduce the loss caused by the impact. At the same time, compared with the buffering design of the spring, it is more stable when placed on the ground. The traditional spring design buffer is easy to shake.

[0034] Specifically, a T-shaped block 221 is provided at one end of the connecting plate 220, and a T-shaped slot 232 is opened at one end of the supporting plate 230. The T-shaped block 221 and the T-shaped slot 232 are adapted to each other. By providing the T-shaped block 221 and the T-shaped slot 232 to be adapted to each other, the plug-in connection between the connecting plate 220 and the supporting plate 230 is achieved.

[0037] In a specific embodiment, the bottom of the bottom plate 250 is arc-shaped, and a rubber pad is provided at the bottom of the bottom plate 250 .

[0038] The working principle of the agricultural drone: During use, the drone body 110 is equipped with a corresponding medicine box or aerial photography equipment. When the drone takes off, if a collision occurs during flight, it will first hit the guardrail 142, thereby providing good protection for the propeller. When landing, the bottom plate 250 first contacts the ground and the impact force is transmitted to the support plate 230 and the connecting plate 220. The connecting plate 220 rotates on the fixed shaft 212, and the connecting plate 220 rotates to squeeze the spring steel sheet 213, and the spring steel sheet 213 is used for buffering to reduce the loss caused by the impact. At the same time, compared with the buffering design of the spring, it is placed on the ground It is more stable and avoids the situation that the traditional spring buffer design is easy to shake. When carrying and disassembling, pull the clamping block 244, the clamping block 244 squeezes the compression spring 242, and at the same time, the end of the clamping block 244 moves out of the clamping shell 243, and then slide the support plate 230 to separate the T-shaped block 221 and the T-shaped groove 232, so as to remove it from the bottom of the drone. Further, the support plate 230 will also drive the insertion rod 231 to move, and the insertion rod 231 is moved out of the fixing tube 251, so that the bottom plate 250 can be disassembled, which is convenient for storage and easy to replace individual components, saving costs.

[0039] It should be noted that the specific model specifications of the drone body 110 and the electric propeller 120 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and principle of the drone body 110 and the electric propeller 120 are clear to those skilled in the art and will not be described in detail here.
