摘要
油茶是一种重要的油料树种。随着我国油茶种植面积的增长,油茶果机械化与自动化采收成为人们关注的热点问题。本文论述了油茶果采摘机器人采摘头的结构设计,并利用Inventor软件对采摘头进行了力学仿真和关键零件有限元分析试验。试验结果表明,最大应力值随振幅和频率增大而增大;振动频率对采摘头关键零件最大应力值影响较大,短连杆和曲柄最大应力值最高,但仍小于材料的屈服强度,结合采摘头现场工作试验,验证了油茶果采摘机器人采摘头的可行性和安全性。
Camellia is a kind of important oil tree species.Tea oil, which is of great value on nutritional and medicinal and has huge market demand, is extracted from the tea seed.With the increase of camellia＇s cultivated area, the traditional manual harvesting have been unable to meet the demand of its scale and industrialization.Realizing the camellia fruit harvesting mechanized and roboticized has been the focus.Aimed at the status quo, camellia fruit picking robot is designed. Firstly, this paper discusses the working principle of camellia fruit picking robots＇ picking monomers, and carries on the 3D structure design. Secondly, this paper proceeds mechanics simulation and finite element analysis text for the the picking monomers and its key parts of the robot used the software of Inventor.The test results show that the maximum stress value of key parts increase along with the increase of amplitude and frequency;vibration frequency of picking monomers has greater influence on the maximum stress value of key parts;the maximum stress value of short connecting rod and crank is highest, but it is still less than the yield strength of material;verifing the picking monomers of camellia fruit picking robot is feasible and security combined with field work picking monomers test.
