In view of the significant variation in orchard planting structures and the inadequate adaptability of existing spraying machinery to non-standardized orchards, this study developed a novel spraying device compatible with both standardized and non-standardized planting scenarios and conducted practical application of the device. The research adopted a technical route combining long-distance low-pressure liquid delivery with low-pressure power transmission, constructing a three-stage integrated structure consisting of a front-end low-pressure annular atomization spray and adjustable air-assisted secondary atomization module, a mid-end integrated composite hose for liquid delivery and power transmission, and a rear-end pressure-sensitive diaphragm pump coupled with a 48–62 V DC power supply system. The device was applied and validated in both quasi-standardized and non-standardized orchards. The results showed that at different motor speeds (3 000–6 000 r/min), the device achieved an effective spraying range of 3.5–6.5 m; the effective spraying area at distances of 2.5–5.0 m was significantly larger than that of conventional hydraulic spray guns; the droplet diameter was controlled between 100–150 μm, with leaf coverage exceeding 90%. In non-structural densely planted pear orchards, the device demonstrated significant effects in reducing operation time and pesticide dosage while improving spraying uniformity.In conclusion, the spraying device designed in this study improves operational efficiency, reduces pesticide waste, and enhances adaptability to complex orchards, providing a reference for the development of general-purpose equipment for mechanized plant protection in orchards.
