针对南方丘陵山地耕地落差大,耕作机具在田间转移困难的问题,以LZ-1WG4.2Q型微耕机为原型,设计一款可快速拆装、易于转移、工作稳定性好的模块化微耕机。设计了发动机过渡节、变速箱过渡节与弹性动力座架总成等主要部件,对薄弱部件进行强度校核,利用有限元分析法对关键部件进行静态和模态仿真分析,结果证明该设计合理、可靠,为未来山地微耕机的模块化、便携化生产提供参考。 Aiming at the problem that the cultivated land in the hilly and mountainous areas of the south is large in scale and the farm machinery is difficult to transfer in the field, a modular micro-tillage machine that can be quickly assembled and disassembled, easy to transfer and good working stability is designed based on the LZ-1WG4.2Q tillage machine machine. The main components of the transition section of the engine, the transition section of the transmission and the assembly frame of the elastic power are designed, and the strength of the weak part is checked. The static and modal simulation analysis of the key components by the finite element analysis shows that the design is reasonable , Reliable, for the future micro-tiller tillage modular, portable production to provide a reference.
