摘　　要：针对马铃薯除杂效率低,伤薯率高等问题,本文对马铃薯除杂装置进行了室内试验,进行秧蔓与薯石一体化除杂,确定了马铃薯除杂装置的最优工作参数。以除秧辊转速、抖动轮频率和挡秧杆长度为试验因素,通过单因素试验探究不同因素对除杂率和破皮率的影响。通过响应面试验,探究各因素共同作用对马铃薯除杂率和破皮率的影响。为使秧蔓与薯石一体化除杂率大于90%,马铃薯破皮率小于5%,本文通过期望函数法确定了除杂装置最优工作方案:当除秧辊转速为125.5 r/min、抖动轮频率为2.4 Hz、挡秧杆长度为280 mm时,除杂率为91.03%,破皮率为3.14%,符合马铃薯除杂要求。To address the issues of low efficiency in potato debris removal and a high incidence of potato injury,an indoor experiment was conducted on a potato debris removal device to identify the optimal operational parameters.The speed of seedling removing roll⁃er,the frequency of shaking wheel,and the length of seedling stopper were taken as the test factors,and the influence of different factors on the removal rate and skin-breaking rate was investigated through the one-factor test.Subsequently,a response surface methodology was utilized to further explore the interactions among the factors and their collective effects on the de-vegetation rate and skin-breaking rate.The optimal working program of the de-hybridization device was determined by using the expectation function method.The results indicated that when the speed of the de-hybridization roller was 125.5 r/min,the frequency of the shaking wheel was 2.4 Hz,and the length of the seedling blocking rod was 280 mm,the de-hybridization rate was 91.03%,and the rate of skin breaking was 3.14%,which met the requirements of the de-hybridization of potatoes.
