生姜自动收获装置的机构设计及运动分析

Mechanism Design and Kinematics Analysis of Automatic Harvesting Device for Ginger

在对生姜收获特性分析的基础上,提出了一种集松土、夹拾、裁剪、抖土功能于一体的生姜自动收获方法。首先进行了收获装置的总体设计,并以四杆机构及其演化机构完成了各执行机构的结构和传动设计,通过对各执行机构的运动分析得出了松土铲的运动轨迹方程、裁剪刀的最大张角和抖土筛子的极位夹角。本装置的设计将为生姜自动收获技术的应用提供科学依据和技术支撑。

An automatic harvesting method of ginger , including loosening soil , clamping , cutting out and shaking soil , was proposed according to its harvesting characteristic .Firstly , the general design of the automatic harvesting device was carried out .Then , structure and transmission plans of actuators were designed based on four -bar mechanism and its de-veloping mechanism .Finally , the motion curve of break shovel , the maximum angle of scissors and crank angle between extreme positions were obtained by the kinematics analysis .The research results will provide scientific basis and technical support for automatic harvesting technology of ginger .
