联合收获机同轴差速轴流脱粒滚筒设计和试验（Design and Test on the Coaxial Differential-speed Axial-flow Threshing Rotor of Combine Harvester）
联合收获机 轴流滚筒 同轴差速
2010/12/28
阐述了联合收获机同轴差速脱粒滚筒的工作原理和结构，并进行了试验研究。在试验的基础上用Matlab离散余弦傅氏分析法，分别建立了单速和差速脱粒情况下不同脱出物轴向分布的数学模型及其分布曲线。结果表明：差速脱粒的籽粒总破碎率为0.67%，杂余产生量为脱出物总量的8.63%，末脱净与夹带损失率为0.76%，分别比单速脱粒下降40.9%、29.5%和32.15%，脱粒的质量优于单速脱粒。同轴差速脱粒装置集...
