新型香蕉种植开坑机的结构设计与空间分析

摘要

基于目前香蕉种植作业方式落后及种植开坑机研制缺乏的现状，研发了一种连杆式可控三自由度香蕉种植开坑机。首先，介绍了新型香蕉种植开坑机的机构原理和结构特点；其次，根据新型香蕉种植开坑机的雅可比矩阵进行奇异性分析，并得出其结构奇异位型；再次，根据数学理论隐含数存在的条件，分析计算新型香蕉种植机结构工作空间的边界条件，得出香蕉开坑机的工作空间；最后，运用 MatLab 软件仿真模拟仿真，得出香蕉开坑机输出点的空间图形。该分析验证了香蕉种植开坑机的可行性和可靠性，具有一定的推广价值。%Based on the banana cultivation practices , banana planting machine development the present situation of the lack of open pit , thie paper developed a connecting rod type controlled three degrees of freedom banana planting machine open pit .First , this paper introduces the new banana planting mechanism principle and structure characteristics of open pit machine , Secondly , according to a new type of banana planting machine open pit singularity of the jacobian matrix and the singular type structure , analysis is made .Again, according to the mathematical theory of several existing condi-tions, calculation of new banana planting machine structure workspace boundary condition , it is concluded that the ba-nana open pit machine workspace .Simulation by using the software of matlab simulation , it is concluded that the banana open pit machine output points of space pattern .The analysis proves the feasibility of banana planting open pit machine and by sex , has certain promotion value .
