摘　　要：介绍一种新型水稻插秧机分插机构──偏心链轮分插机构，其传动部分是由５个偏心链轮组成：１个太阳轮、１对行星轮（与载植臂团结）和１对张紧轮。在优化太阳轮和行星轮参数时，把取秧角、插秧角、秧针轨迹、轨迹高度作为目标函数，在确定目标函数时，要求适应双季稻插秧，在优化张紧轮参数时，把链条处于张紧状态下，其长度变化最小作为目标函数。在理论上确定了主要机构参数，研制了分插机构传动部分，并通过试验台验证了理论模型和优化方法。A new type of rice transplanting mechanism-transplanting mechanism with eccentric sprockets is introduced, the essential elements in the mechanism drive include a sun sprocket, a pair of planet sprockets(planting arms were fixed on them) and a pair of tensioner sprockets. Mathematical model is founded on the basis of using the angle of taking seedling and planting seedling, seedling claw path, and path height as optimum object-function, the primary parameter of transplanting mechanism is determined. The drive part of transplanting mechanism is developed and the optimum method is proved by test. The national-invention patent for this mechanism is applied for.
