摘　　要：针对丘陵山区小型燃油式作业机不环保、电动式作业机作业效果不佳等问题,对丘陵山区小型电动作业机的设计进行阐述,重点阐述其结构及参数、控制方法的设计。该设计的丘陵山区小型电动作业机,采用双电机分别驱动行走轮和刀辊,不仅环保性能好,还能在满足耕深条件下根据作业载荷情况自动调整两电机的工作转速,实现自动化连续、稳定、可靠作业,操作简便,作业效率和性能、节能性优良;同时,刀辊驱动的中间传动采用具有差速比且可对调使用的结构设计,再通过改变刀辊电机旋转反向方式改变刀辊的转速及转向并更换刀辊,使得该机可作为微耕机或培土机使用,实现一机多用,大大降低用户购机成本。Aimed at the promblems of small fuel powered operation machine in hilly and mountainouns areas anr not environmently friendly and operation performance of electric work machines are not good,this article elaborates on the design of small electric operating machine in hilly and mountainous areas,with a focus on the design of their structure,parameters,and control methods.The small electric operating machine designed for hilly and mountainous areas adopts dual motors to drive the walking wheel and knife roller respectively.It not only has good environmental performance,but also can automatically adjust the working speed of the two motors according to the working load situation under the condition of meeting the plowing depth,achieving automatic continuous,stable and reliable operation.It is easy to operate,with excellent work efficiency,performance and energy saving;At the same time,the intermediate transmission of the knife roller drive adopts a structural design with differential speed ratio and adjustable use.By changing the rotation direction of the knife roller motor,the speed and direction of the knife roller can be changed and the knife roller can be replaced,so that the machine can be used as a micro tiller or soil cultivator,realizing the multi-purpose connection of one machine and greatly reducing the user's purchase cost.
