Abstract: This study addresses poor adaptability of fixed pipelines, high labor intensity of manual spraying, limited liquid endurance of agricultural drones, and insufficient aerial-ground coordination in fragmented orchards, nurseries and hilly forest land. A straw-man-like modular irrigation machine is proposed with an upper UAV platform, a liftable and foldable spraying mechanism, a modular liquid tank and an internal load-bearing frame. A perception-decision-execution-feedback loop is established. ANSYS static simulation uses PVC Foam, a 2 mm tetrahedral mesh, fixed bottom support and a 200 N equivalent load. After a 3 mm local thickening of the bottom load-bearing area, maximum total deformation decreases from 10.639 mm to 3.0605 mm and maximum equivalent stress from 9.5925 MPa to 5.2799 MPa. A hierarchical control system, UAV blind-spot compensation strategy, safety interlocks and virtual-prototype verification are further integrated.
