摘　　要：为了解决鸭嘴移栽机的自动取苗问题,以齿轮-五杆机构为基础设计了自动取苗装置,通过仿真优化机构参数,获得了理想的取苗轨迹,并优化了机构的动力学特性。在此基础上设计了自动取苗试验台,通过试验验证了齿轮-五杆取苗机构的合理性和可行性。In order to achieve the automatically seedling pick-up of duck-billed transplanter,a geared five-bar linkage seedling pick-up device was introduced.The ideal pick-up trajectory was obtained by simulation and optimization of structural parameters.The dynamic characteristics of the proposed device were also optimized.On the basis of theoretical studies,a seedling pick-up bench was designed.Experiment results showed that geared five-bar linkage seedling pick-up device was feasible and rational.
