以黄淮海地区为代表的一年两熟制地区，由于玉米可生长期短、收获时间紧，收获时果穗含水率较高，摘穗时易产生断茎，且苞叶与果穗贴合紧密，剥皮作业质量效果较难保证，剥净率与啃穗率、脱落籽粒破损之间矛盾突出。目前，对高含水率（≥40％）果穗剥皮装置的系统理论与试验研究均较少，因而本文设计了5因素玉米剥皮试验装置，可以进行槽型布置和平面布置两种剥皮装置的室内试验。通过调整压送器与剥皮辊距离、剥皮辊倾角、剥皮辊转速、压送轮转速及剥皮辊组合形式等关键因素水平，以苞叶剥净率、啃穗落粒率和籽粒破损率为评价指标，进行多因素多水平正交试验，确定剥皮装置的最佳参数组合，为玉米联合收获机剥皮装置选型和参数设计提供依据。

In wheat-maize rotation cropping areas such as Huanghuaihai region , owing to the short growth period , tight harvest time , high moisture rate , high trash content percentage , closely connection between bract and ear , maize harvest is meeting with the difficulties of poor working quality stability , clean husked ear rate is restricted by the bit ear rate and exfoliated kernel damaged rate .So far , the research on the high moisture rate ( more than 40%) corn husker , either sys-tem theoretical or experimental ,is rarely.Based on this status , researchers design a five factors corn husker experiment device which can be used for laboratory test .This study chose the table orthogonal test method .The equipment parame-ters, which indicated the critical different factors and levels , can be adjusted conveniently , such as distance between compressing wheel and peeling roller , inclination of roller angle ,rotating speed of peeling roller and compressing wheel , the style of peeling roller had been combined .This study chose three evaluation indexes , which were clean husked ear rate, bit ear rate and exfoliated kernel damaged rate , for evaluating the better parameter combination , and then maybe provide evidence in designing corn combine harvester or choosing corn husker parameter .
