为适应蔬菜大棚的大规模发展,解决农业污染,提出一种混合动力控制方法及用于微型自耕机的混合动力装置,具有操作方便、体积小、零排放的优点。分析了该设计的技术难点和解决方案;通过Simulin软件,开发氢燃料-锂离子电池混合动力系统仿真平台和分析微型自耕机的3种工作状态;运用计算机设计软件Solidworks,对微型自耕机的各个零部件进行了三维建模并进行装配;其核心零件动力制器采用凹凸方式设计。样机测试证明,微型自耕机的各项性能指标均已达到国际标准要求,整机质量为40 kg,操作灵活、转移方便、制造成本较低。

In order to adapt to the large-scale development of vegetable greenhouses,solve agricultural pollution,easy to operate,small sizeand zero emission,a hybrid control method and hybrid device were proposed.The technical difficulties and solutions of the design wereanalyzed.The simulation platform of hydrogen fuel lithium ion battery hybrid power system was developed and the three working states of themicro self tiller were analyzed by using simulin software.The components of the micro self tiller were analyzed by using Solidworks software 3 Dmodeling and assembly.The core part of the power brake was designed with a concave-convex method.The prototype test shows that all theperformance indexes of the micro self tiller have reached the requirements of international standards,the whole machine weight is 40 kg,theoperation is flexible,the transfer is convenient,and the manufacturing cost is low.
