摘要
随着计算机辅助设计技术的发展,SolidWorks等三维设计软件已广泛应用到农业机械设计当中。基于降低菠萝茎叶粉碎还田作业劳动强度,降低作业成本的原则,针对目前菠萝茎叶粉碎还田机需2次作业才能达到农艺要求、粉碎效率低,作业成本高的问题,结合菠萝茎叶粉碎难点,运用参数化造型软件SolidWorks对菠萝茎叶还田机进行参数化造型,设计出新型的双轴式菠萝茎叶粉碎还田机,并对虚拟样机关键零部件进行运动仿真及模态分析,理论上确保了样机结构的可靠性及工作的合理性,并为该类型农机具的设计及初步优化提供参考。
With the development of CAD technology, SolidWorks and other three-dimensional design software have been widely used for designing agricultural machinery. In this article, based on principle of reducing operating costs and labor intensity of chopping pineapple stems and leaves, a new type of two-axis field pineapple stem-leaf chopper was designed using SolidWorks, aiming at the problem of current low efficiency equipments working two times to achieve agronomic targets. Then motion simulation and modal analysis for virtual prototype of key components was achieved, the results showed that the new type of two-axis field pineapple stem-leaf chopper satisfyied requirements in theory. A new method for designing and optimizing this kind of machinery was provided.
