【摘要】 我国植保机械相对国外较落后,存在农药利用率低、劳动强度大及农民中毒现象频发等问题。为此,对高地隙自走式植保机械喷杆系统结构做了简要叙述,并对喷杆展开机构进行了自由度分析计算及运动学理论分析;同时,运用ADAMS仿真软件对喷杆展开机构进行了运动学仿真分析,提出了将液压缸替换为电推杆的优化方案,并对优化后的方案进行了运动学仿真分析。结果表明:优化后的展开性能明显提高,这一改进为自走式植保机械的进一步发展提供了依据。更多还原

【Abstract】 The plant protection machinery of China is relatively backward compared to the foreign plant protection machinery. There are the problems of low pesticide use,labor- intensive,poisoning of farmers frequently and so on. In this paper,highland clearance for plant protection machinery self- propelled spray bar system structure is described briefly,and the degree of freedom of Spray bar deployment mechanism and the kinematics theory are analyzed and calculated. The kinematics simulation analysis is carried out by simulation software of ADAMS. Proposing the optimization program that replacing the hydraulic cylinder with electric putter. Finally carry out the kinematics simulation analysis to the optimized program. The performance of expand has improved significantly. This improvement provides foundation for the further development of self- propelled plant protection machinery.更多还原
