| 摘 要： | 在专用的复脱分离试验装置上,对SG800摘脱机脱穗后的混合物,进行了多因素的性能试验,得出了复脱转筒线速度、凹板栅板间距、脱粒间隙、喂入量等诸因素,与未脱净率、破碎率、夹带损失率、含杂率和功耗等性能指标的相关性及其显著程度,作了因素水平参数组合的初步优选;并测定分析了复脱分离后排出物组成和各性能指标的轴向分布状况;探讨了改善复脱分离性能的途径。

| Abstract: | Multiple-factor studies to investigate the rethreshing and separating of stripped paddy mixture, which was obtained by the SG800 stripper made by Silsoe Research Institute, Britain and IRRI, Philippines, on a special experimental device has been undertaken.The significances of factors included; cylinder rotary speed, distance between concave bars, clearance between cylinder and concave, feeding rate, on the performance index of unthreshed rate, broken rate, gripping loss rate, trash rate and power consumption were obtained from analysis of variance. The optimum combination of the factor levels has been discussed.The material after rethreshing and separating was collected along the axial direction sector by sector underneath the concave and straw dischange end of the device. The components and the distribution of the performance index have been analysed, and the results can be applied as references for the selection and design of rethreshing device and other processing mechanism. |
