摘　　要：以丰花5号花生种子为研究对象,通过种子物理结构特性分析,设计了倾斜圆盘碟式排种器。在JPS-12型排种器试验台上进行了二次旋转组合试验,建立了排种器分种碟转速、倾斜角度、分种碟半径与排种器性能指标(穴粒数合格率、重播率、空穴率和破碎率)的回归方程,分析了排种器的排种性能。优化计算得出,分种碟半径为125 mm,倾斜角度为22°,分种碟转速为38 r/min,排种器的综合性能达到最优值94.67%。In order to improve the adaptability and working precision of the metering device on peanut seeder, the most widely used peanut seeder-Fenghua 5 is selected to study and a new declined disc metering device is designed according to the analysis of the peanut seed physical attributes. Based on the results of the orthogonal rotational combination experiment on the metering device test bed JPS - 12, the performance of the metering device is analyzed and the regression equation is obtained between working parameters （metering disc velocity, declination angle, metering disc radius） and metering performance index （ percentage of pass, percentage of rebroadcast, percentage of cavity and percentage of damage）. Finally, it is concluded that the optimum metering performance can be obtained when the radius of the metering disc is 125 mm, the disc declination angle is 22°, and the metering disc velocity is 38 r/rain.
