作品说明：Nowadays, smart agricultural sprinklers are increasingly being used in the agricultural field to remotely spray crop areas, sense crop and field conditions, and help improve the yield and quality of crops. However, from the technical point of view of the current situation, it is difficult for ordinary intelligent agricultural sprayers to carry out the fine spraying operation of the whole system, so that there are problems such as waste of resources, uneven distribution of spraying amount, and low operation efficiency in the process of a large number of agricultural spraying. Therefore, in order to improve the yield and quality of crops, and improve the utilization efficiency of labor and resources, the smart agriculture spraying aircraft was designed. The smart agriculture spraying aircraft has carried out a high-precision and systematic overall design such as fixed-point, quantitative, and positioning. The agricultural smart spraying drone adopts a modular design and is equipped with an adjustable sprinkler device (including a temporary storage water tank, a hollow beam and a detachable sprinkler head) to support centimeter-level accurate positioning and variable spraying. Its split platform can switch between liquid/solid medicine boxes, and integrates intelligent sensor matrices (such as multispectral cameras, lidars) and AI algorithms to realize the identification of pest and disease areas and dynamic dosage adjustment. Equipped with centrifugal atomization system and magnetic transmission impeller pump, the uniformity of fog droplets is increased by 40%, the coverage rate of the back of fruit tree leaves is increased by 2 times, and the average daily operating area is 500-800 mu. The lightweight fuselage and RTK navigation network ensure stable operation at low altitude, and the utilization rate of pesticides is increased by more than 30%.
