本发明的工作原理：
当微型双动力电动拖拉机需要工作时，通过电力驱动控制***(8)启动直流电机(6)，实现整机从机库到温室大棚之间的转移：待进入温室大棚后，整机动力来源切换至由交流电机(10)提供，通过电力驱动控制***(8)控制交流电机(10)的转速和转向，进而带动农具进行温室大棚作业，在作业过程中，可对电池组(7)进行充电以实现微型双动力电动拖拉机返回机库。
本发明结构简单，发明了一种微型双动力电动拖拉机，在保持温室作业机械环保无污染、噪声小等优点基础上，实现了温室作业机械续航时间的大幅度提升，不仅提高了温室作业机械的工作效率，还有助于推动温室大棚作业机械的发展，具有较强的推广使用价值。
