The invention provides a distributed driving type double-battery-pack small greenhouse electric crawler tractor. The tractor mainly comprises lithium iron phosphate battery packs, chargers, contactors, DC-DC converters, 12V lead-acid batteries, a chassis, a driving motor, a driving motor controller, a motor speed reducer, an electric appliance cabinet, a support, a PLC, an industrial personal computer, a three-dimensional laser radar and a solid-state laser radar. Energy is provided by the two high-capacity lithium iron phosphate batteries, and the endurance time is long. The PLC can control the on-off of the contactor to realize the switching and on-off of a circuit of the lithium iron phosphate battery pack, so that the function that two lithium iron phosphate batteries independently provide electric energy for the tractor is realized, the endurance time is prolonged, and the safety of operators is ensured; and meanwhile, the walking mechanisms on the two sides are powered by independent motors, the power performance is good, and the pivot steering function can be achieved.

    本发明提供了一种分布驱动式双电池组小型温室电动履带拖拉机,其主要组成部分包括磷酸铁锂电池组、充电器、接触器、DC‑DC转换器、12V铅酸电池、底盘、驱动电机、驱动电机控制器、电机减速器、电器柜、支架、PLC、工控机、三维激光雷达、固态激光雷达。本发明由两块大容量的磷酸铁锂电池提供能量,续航时间长。PLC能够控制接触器的通断实现磷酸铁锂电池组电路的切换与通断,从而实现两块磷酸铁锂电池单独为拖拉机提供电能的功能,提升了续航时间,保证操作人员的安全性;同时两侧的行走机构由单独的电机提供动力,动力性能好且可以实现原地转向的功能。
