In order to further optimize the operation efficiency of rotary cultivator equipment in China and ensure the soil quality of rotary cultivator,the structure design of rotary cultivator was studied based on the intelligent manufacturing numerical control processing technology.On the basis of the composition layout and parameter characteristics of the rotary cultivator,according to the accuracy and speed requirements of CNC machining,the mathematical model of the position and posture relationship between the machining tool and the machining parts was established,and then was reasonably applied to the parameter optimization design of the core parts of the rotary cultivator,Finally,the matching NC machining scheme was determined.Through the optimized operation test of rotary cultivator,the results showed that in the normal field environment,the performance parameters of rotary tiller were significantly improved by the effective integration of CNC machining concept and structural design,the tool durability and soil breaking rate of rotary tiller were increased by 7.23%and 7.22%respectively,and the overall efficiency was maintained at 90%.Above all,the test effect was very good.The analysis method started from the source of agricultural machinery structure design,and effectively implemented the essential design of rotary cultivator components,which had a certain degree of innovation and progressiveness,and would be some good inspiration for the improvement of other agricultural machinery and equipment.
