Description

Technical Field

[0001] The utility model relates to the technical field of agricultural pesticide application, in particular to a fruit tree pesticide application device for an agricultural unmanned aerial vehicle. Background Art

[0002] Plant protection drones, also known as 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. The spraying operation is achieved through ground remote control or navigation flight control, and can spray pesticides, seeds, powders, etc. With the rapid development of drone technology, the more widely used "agricultural drones" are gradually replacing "plant protection drones". Agricultural drones are not only used for spraying and applying pesticides, but also for spreading fertilizers, sowing seeds, spreading feed, etc., to meet the diverse needs of farmers and improve production efficiency. Unmanned small helicopters have low operating heights, less drift, can hover in the air, and do not require a dedicated take-off and landing airport. The downward airflow generated by the rotor helps to increase the penetration of the fog flow into crops, with high prevention and control effects, long-distance remote control operation, spraying operators avoid the risk of exposure to pesticides, and improve the safety of spraying operations. In addition, the electric unmanned helicopter spraying technology uses a spray spraying method that can save at least 50% of pesticide usage and 90% of water usage, which will greatly reduce resource costs. The use of drone spraying greatly reduces the risk of contact caused by the gathering of people.
