Abstract: In order to execute precise spraying and improve the utilization rate of pesticide, a multi-degree-of-freedom symmetrical twostage rocker mechanism was proposed. According to the principle of wind driven spray technology for fruit trees, a real time adjustable spraying mechanism based on working attitude and spray distance was designed. Through mathematical modeling and software optimization, the spray point kinematics equation was deduced. The maximum height and width of the sprayer were 2 951.5 mm and 1704.5 mm, respectively, and the maximum lateral and longitudinal adjustable values were 695.4 mm and 680.4 mm, respectively, which made the spray distance precise and adjustable. The maximum force of each hinge point was only 338.94 N during the operation, which ensured stable and reliable work. The response characteristics of the mechanism showed that the flexible profiling mechanism operated stably. The horizontal expansion time of the mechanism was 12.5 s, and the lifting time was 36.2 s, while the extension time of each putter was 19.2 s. The spray deposition characteristics test showed that the coverage rate of the profiling spray was 43.85%, and the coefficient of variation was 26.63%, which was better than the fixed spray’s 29.97% and 39.05%. This study provides technical support for the design and application of profiling spray equipment.
