连杆自锁式花生拔采机的设计与有限元分析
|
摘要
设计了一种连杆自锁式花生拔采机,可实现花生机械化拔起采摘的功能。通过对个体农户人工采摘花生现状的分析,给出了花生拔起动作和采摘工艺流程,设计出一种适合大面积花生拔起采摘机,利用UG建立三维模型导入ADAMS和MATLAB进行仿真,并利用ANAYS进行有限元分析,最后进行研制。该拔起采摘机可以高效完成花生拔起采摘动作,关键部件满足强度和刚度要求,并能适应花生在播种过程中存在的直线误差问题,实现了多自由度的拔采,对提高大面积花生采摘效率、减少劳动强度具有重要意义。
Objective Design and research a connecting rod self-locking peanut mining machine to achieve function of pulling up peanut to picking mechanically. Methods Through the analysis on the current status of artificial picking peanut for individual farmers,the technological process of picking and the action of pulling up was analyzed,a peanut mining machine fitting for large area peanut was designed. Using UG to establish a three-dimensional model and using ANAYS to carry out finite element analysis,the machine is tested finally. Results The machine can efficiently complete the picking action of the peanut. Conclusion this machine has good adaptability,implementation of mining multi degree of freedom with a wide range of purposes,realizing the peanut mining work do pull machine. To improve the efficiency of large areas of peanut harvesting,reduce labor intensity is of great significance.
