Description

Technical Field

[0001] This utility model relates to the field of agricultural aviation equipment technology, and in particular to a farmland spraying drone. Background Technology

[0002] Agricultural spraying drones are intelligent plant protection devices specifically designed for the control of agricultural pests and diseases. Utilizing advanced flight control and pesticide spraying systems, they achieve efficient and precise pesticide application in farmland. Through high-precision GPS navigation and intelligent sensor technology, these devices can automatically plan flight paths and evenly spray pesticides, effectively reducing pesticide waste and labor costs. In recent years, with the advancement of large-scale agricultural production and technological development, agricultural spraying drones have been widely used in large farms, significantly improving crop protection efficiency and production sustainability, becoming an important tool in modern agriculture.

[0003] Existing agricultural spraying drones have a fixed structure; their robotic arms and nozzles cannot be folded, resulting in large space requirements for transportation and storage, increasing handling difficulty and storage costs, and making them particularly unsuitable for small transport vehicles or confined storage environments. Furthermore, their functionality is limited; spraying and sowing require separate equipment, and switching between operation types necessitates replacing the entire device, leading to cumbersome and inefficient operation. Simultaneously, most drones lack material monitoring capabilities, making it difficult to monitor pesticide or seed levels in real time, which can easily affect operation progress due to untimely resupply. Insufficient motor control precision can also lead to uneven spraying or sowing. To address these technical problems, this application proposes an agricultural spraying drone. Utility Model Content

The length of the centrifugal nozzle 6 is greater than the length of the connecting column 17. A circular retaining ring is fixedly connected to the middle of the screw 18. After the operation is completed, loosen the bolts connecting the limiting ring 16 and the connecting block 10, open the limiting ring 16 to allow the mechanical rod 2 to achieve a folding effect through the rotation of the rotating shaft 15 and the connecting block 10. Loosen the screw 18 to fold the centrifugal nozzle 6 to the bottom of the mechanical rod 2, and then tighten the screw 18. The centrifugal nozzle 6 can also be folded to save placement space. The sensor 11 connected to the storage box 5 can detect the weight of the material inside the storage box 5.

When sowing is needed, the first connecting pipe 22 and the second connecting pipe 24 are disconnected. The second motor 19 drives the screw rod 21 to sow the seeds.
