摘要
本文主要以沉水植物收获机械明轮推进器的连杆机构为研究对象，确定蹼板入、出水角，最小传动角和偏心距的较优组合，从而提高明轮推进效率。
Taking the connecting rod mechanism of the propeller wheel of aquatic plant harvester as an object of study,we attempt to determine the optimistic combination of diving angle and emerging angle of webplates,minimum transmission angle and eccentric distance in order to raise the efficiency of propeller wheel.
