摘　　要：针对我国燕麦机械化收获时杂余含量高和未脱净严重的问题,在分析了现有谷物收获机脱粒装置结构的基础上,提出了一种适用于裸粒型燕麦的脱粒方案,设计了一种燕麦脱粒组合式轴流滚筒,并在实验室搭建了燕麦脱粒试验台。选取影响装置脱粒性能的3个关键因素(主滚筒转速、脱粒间隙、喂入量)为研究对象,在预试验的基础上对3个关键因素的参数组合进行了优化。结果表明:在喂入量为1.46kg/s,主滚筒转速、脱粒间隙分别为1059r/min、12mm时,含杂率和未脱净率均最低,分别为19.39%,0.72%。经试验验证,在允许误差为2%时,其试验结果可信。There are some serious problems in the mechanized harvesting of oats in China, such as high content of impurities and no threshing. based on the analysis of the structure of the existing corn harvester threshing device, this paper proposes a scheme is suitable for the size and the shape of naked oats threshing, designs an oat using combined drum of axial flow threshing and set the oat threshing test-bed in the laboratory.Three key factors(speed of main drum, threshing clearance and feeding quantity) that affect the threshing performance of the device are selected as the research object. The parameter combination of the three key factors is optimized based on the pre-test.The results showed that: when the feeding amount was 1.46 kg/s, the rotation speed of the main drum and the threshing clearance were 1059 r/min and 12 mm respectively, the impurity and non-removal rates were the lowest, 19.39% and 0.72% respectively. It is verified by experiments that the test results are reliable when the allowable error is 2%.
