Abstract: In order to solve the practical problems of the axial flow rice combine harvester threshing separation unit which is high power consumption during operation and high impurities in mixture that maybe increased the cleaning load,the author developed a new nails teeth axial flow unit and carried out the threshing and separating test with rice.Established the mathematical models among feeding amount,roller rotary speeds,concave clearance,power consumption,impurity rate,broken spike rate and total loss rate of the four performance evaluation indicators.Obtained the sequence that the factors influenced the performance evaluation index.Realized the multi-objective optimization with Matlab,obtained the best parameters combination for device.The feeding amount is 2kg/s,the roller rotary speed is 600r/min,the concave clearance is 30mm,and completed the verification test with the best parameters combination,the result provided a theoretical basis on the development of rice combine harvester and the transformation of traditional models in China.
