摘　　要：谷子机械化收获水平较低,与成熟的稻麦收获机械化水平相比仍有较大差距。为此,针对谷子收获机械脱粒分离装置存在的问题,研制了单轴流谷子脱粒分离装置试验台,采用单因素试验、正交试验方法,通过方差、极差分析研究滚筒转速、喂入量、脱粒间隙对谷子脱粒分离质量的影响规律,验证装置脱粒性能。结果表明:各因素影响脱净率和谷码率主次顺序依次是滚筒转速>脱粒间隙>喂入量>凹板筛格间距;各因素影响于损失率主次顺序依次为脱粒间隙>凹板筛格间距>喂入量>滚筒转速;优化获得较优参数组合为滚筒转速950r/min、喂入量2kg/s、脱粒间隙8mm、凹板筛格间距8mm。对较优组合验证,其结果为脱净率91.1%,谷码率8.1%,损失率0.8%,满足谷子收获国家标准。Due to the low level of mechanized harvest of millet,there is still a big gap between the level of mechanized harvest of rice and wheat.Therefore,in view of the problems existing in the threshing and separating device of millet harvester,the test-bed of single axial flow threshing and separating device is developed in this paper.By means of single factor test and orthogonal test,the influence of drum speed,feeding amount and threshing gap on the quality of threshing and separation was studied by variance and range analysis,and the threshing performance of the device was verified.The results show that the main order of influence is drum speed>threshing clearance>feeding amount>concave sieve bar spacing for the threshing rate and millet agglomerates rate;the main order of influence is threshing clearance>concave sieve bar spacing>feeding amount>drum speed for the loss rate.The optimum parameters of the device are drum speed of 950r/min,feeding amount of 2kg/s,concave sieve bar spacing of 8mm,threshing clearance of 8mm.The results show that the threshing rate is 91.1%,the millet agglomerates rate is 8.1%,and the loss rate is 0.8%,which meets the national standard of grain harvest.
