单行直插式木薯种植机的设计与优化

木薯大多种植在热带、亚热带地区，这些地区多为黏质土壤并且天气多雨，导致木薯种植劳动强度大、人工效率低下等问题。结合中耕施肥、除草等管理需求和木薯种植农艺要求，设计了具有七连杆机构的单行木薯直插式种植机。木薯种植机的动力来自拖拉机动力输出轴，经过2组链轮分别为分种装置和七连杆机构提供动力。通过辅助软件Solidworks对杆件长度、鸭嘴栽植器安装位角度θ参数进行优化建模，将建模导入有限分析元软件Adams进行仿真分析，通过改变主要杆件长度来获取栽植器机构的运动轨迹。用Adams软件对机构性能的主要参数变量进行优化，得到可以满足单行直插式木薯种植机的设计。

Design and Optimization of Single Row In-line Cassava Planter

Cassava is widely planted in tropical and subtropical areas， where the soil is cohesive and the weather is more rainy，which leaded to problems such as high labor intensity and low labor efficiency in cassava planting. Combined with the management requirements of intercropping， fertilization and weeding and the agronomic requirements of cassava planting， this paper designed a single row cassava in-line planter with seven link mechanism. The power of cassava planter comed from the tractor power output shaft， which provided power for the seed separation device and seven link mechanism through 2 groups of sprockets. The length of seven bar component and the installation position angle θ of duckbill planter were used to construct parametric model through the auxiliary software Solidworks.And then the modeling was imported into Adams for simulation analysis to obtain the motion trajectory of the planter mechanism by changing the parameter length of the main rod mechanism. The main parameters related to performance were optimized using ADAMS software to obtain the design meeted single line in-line cassava planter.
