The invention discloses a pure electric miniature excavator design and belongs to the technical field of electric excavators, the pure electric miniature excavator structurally comprises an electric operation system, a rotation system, a walking system and a battery, in-situ replacement is carried out on the basis of a hydraulic miniature excavator, and the battery is adopted to replace an oil tank to serve as a power source; the walking system sends an action instruction through an operating rod to control a motor to rotate, and the motor drives a crawler chain through a speed reducer and driving teeth to enable target equipment to perform specified actions. The rotation system sends an action instruction through an operation rod to control a motor to rotate, and the motor transmits rotation motion to a rotation bearing outer gear ring meshed with a gear through a speed reducer and the gear to drive target equipment to conduct specified action. The electric working system sends an action instruction through an operating rod to control a motor to rotate, the motor transmits rotation motion to a ball screw pair through a speed reducer and a gear transmission pair, a lead screw in the lead screw pair is made to rotate, and a nut drives an electric cylinder push rod to do reciprocating rectilinear motion under driving of lead screw rotation torque. And the electric cylinder drives the target equipment to perform specified actions.
本发明专利公开了一种纯电动微型挖掘机设计，属于电动挖掘机技术领域，结构包括电作业系统、回转系统、行走系统、电池，本发明专利在液压微型挖掘机的基础上进行原位替代，采用电池替代油箱作为动力源，行走系统通过操作杆发送动作指令控制电机旋转，电机通过减速器和驱动齿，驱动齿带动履带链条使其目标设备进行规定动作。回转系统通过操作杆发送动作指令控制电机旋转，电机将旋转运动通过减速器和齿轮传递至与齿轮啮合的回转支承外齿圈驱动目标设备进行规定动作。电作业系统通过操作杆发送动作指令控制电机旋转，电机将旋转运动通过减速器和齿轮传动副传递至滚珠丝杠副，使丝杠副中的丝杆进行旋转，在丝杠旋转力矩的驱动下，螺母带动电动缸推杆做往复直线运动，使得电动缸带动目标设备进行规定动作。
