摘　　要：穴盘育苗是我国现代化育苗的主要方式,针对穴盘苗人工移栽或半自动移栽作业效率低、作业劳动强度大、作业质量差等问题,为全自动移栽机设计了一种运行稳定、高效的自动取苗装置,基于齿轮-凸轮-连杆复合机构实现符合农艺要求的取苗工作轨迹。建立了取苗装置的数学模型,推导了凸轮槽的理论廓线方程和实际轨迹方程。采用SolidWorks软件和Adams软件,构建了取苗装置的三维模型和虚拟样机模型,得到了仿真工作轨迹。制作了取苗装置的物理样机,并进行了样机试验,结果表明:实际工作轨迹与理论轨迹、仿真轨迹具有较好的一致性。Plug-seedlings are the main way of modern seedling cultivation in China.Aiming at the problems of low efficiency,high labor intensity and poor work quality for manual transplanting or semi-automatic transplanting of plug seedlings,a stable and efficient automatic seedling picking device is designed for the automatic transplanting machine.It is based on the gear-cam-link composite mechanism to realize the seedling trajectory in accordance with the agronomic requirements.The mathematical model of the seedling picking device is established,and the theoretical profile equation of the cam groove and the actual picking trajectory equation are deduced.The 3D model and the virtual prototype model of the seedling device are constructed,and the simulation trajectory is obtained,by using SolidWorks and Adams software.A physical prototype of the seedling device is fabricated and a prototype test is performed.The prototype test results show that the actual working trajectory has good consistency with the theoretical trajectory and simulation trajectory.
