[0002] In the existing technology, a variety of automated tree-planting equipment has been disclosed in the field of mechanized planting of desert vegetation, but there are still technical bottlenecks in the automation integration in the seedling pre-loading stage. Specifically, in the seedling transportation link, the existing equipment mostly adopts an operation mode of manual sorting and positioning of each seedling. This method requires operators to physically isolate and arrange the seedlings to prevent overlap, resulting in limited operating efficiency and high labor costs. Although some improved equipment has tried to introduce a mechanical feeding mechanism, its transmission system generally adopts an independently driven discrete control architecture, and there is a lack of motion coordination mechanism between the execution units. This not only causes additional energy consumption, but also makes it more prone to motion interference, forcing the operator to frequently adjust the phase parameters to maintain the synchronization of the mechanism.
