摘要:
为解决小麦脱粒中脱净率低、损伤率高的问题,对小麦脱粒标准弓齿进行创新设计,并对其脱粒界面进行分析。设计刚柔耦合式弓齿小麦脱粒试验台,开展二次回归正交对比试验,损伤率明显降低,降幅最大可达到1.04%,脱净率明显提高,增幅最大可达到4.64%。试验因素对刚柔耦合式弓齿损伤率的影响程度由大到小依次为滚筒转速、喂入量和脱粒间隙,得到损伤率最优作业参数组合:滚筒转速为350 r/min,脱粒间隙为30 mm,喂入量为6 kg/s。试验因素对刚柔耦合式弓齿脱净率的影响程度由大到小依次为滚筒转速、脱粒间隙和喂入量,得到脱净率最优作业参数组合:滚筒转速为600 r/min,脱粒间隙为10 mm,喂入量为3.5 kg/s。
