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125.5r/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.
Abstract
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.
