In response to prominent issues in existing wine grape cultivation, such as complex power machinery integration, inconvenient connection operations, and low efficiency of unilateral walking operations, a gantry track-mounted multifunctional operations platform for wine grapes was developed. The platform spans across grape trellises, enabling dual-sided operations in a single pass. Considering the high stability requirements for wine grape operations, the track walking device and hitch-lifting mechanism were developed. To accommodate the varying speed requirements of different operational stages, engine power and gearbox gear selection were calculated and selected. Structural strength analysis, steering performance analysis, and overall stability analysis of the machine were conducted. Field test results indicate a maximum operating speed of 3.85 km/h and a minimum turning radius of 3.95 m, meeting the needs of field operations. The maximum climbing angle is no more than 18°, and the machine experiences no lateral sliding or tipping when the maximum lateral tilt angle is below 28°. The hitch-lifting mechanism showed an average settlement of 1.58 mm when lifting to different heights, with a stability rate of 99.7%. This study demonstrates that the developed multifunctional operations platform can meet the field operation requirements of wine grape cultivation. |
