中文摘要：

针对现有中耕培土机械对环境污染严重的问题,结合实际农艺要求,设计电动旋耕培土机的机构形式以及传动系统参数,运用有限元方法对旋耕刀进行静力学分析,确定弯刀类型,研制一种电动旋耕培土机。所研制的电动旋耕培土机有关性能符合国家中耕机械相关标准要求,且具有低噪声、低排放、零污染的特点;其作业效率可达0.121hm^2/h,耗电量约为30.71kWh/hm^2,折合电价18.43元/hm^2,其作业效率以及经济性能均远高于同功率汽油机。

英文摘要：

Against existing mechanical cultivators earth serious environmental pollution problems,combined with practical agronomic requirements,the form of organization as well as an electric rotary Hillers transmission parameters were designed,rotary knife was get on static analysis by using the finite element method,it was matched identified type,electric rotary Hillers were developed.The relative performance of electric rotary hillers conforms with the provisions of the relevant standards,and the characteristics of low noise,low soot emissions and zero pollution;the farming efficiency per hour is about 0.121 hectare,the power consumption is about30.71 kWh per hectare,about 18.43 Yuan per hectare,its farming efficient and economic performance are much higher than the gasoline rotary hillers with the same power.
