    摘要:

    以豐花5號花生種子為研究對象,，通過種子物理結(jié)構(gòu)特性分析,，設(shè)計了傾斜圓盤碟式排種器。在JPS-12 型排種器試驗臺上進(jìn)行了二次旋轉(zhuǎn)組合試驗,，建立了排種器分種碟轉(zhuǎn)速、傾斜角度,、分種碟半徑與排種器性能指標(biāo)（穴粒數(shù)合格率,、重播率、空穴率和破碎率）的回歸方程,，分析了排種器的排種性能,。優(yōu)化計算得出，分種碟半徑為125 mm,，傾斜角度為22°,，分種碟轉(zhuǎn)速為38 r/min，排種器的綜合性能達(dá)到最優(yōu)值94.67%,。

    Abstract:

    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/min. 
