| 摘 要： | 刚性脱粒冲击力较大,造成水稻籽粒破碎或破损.为了降低脱粒过程籽粒破碎或破损,设计了柔性脱粒滚筒,并对其开闭型式、脱粒齿直径、长度和迹距等结构参数进行了试验.单因素试验结果表明:脱粒齿直径、齿长对脱粒性能影响极显著,齿迹距对脱粒性能影响不显著,滚筒型式对脱粒性能影响有差异.正交试验结果表明:脱粒齿直径和齿长的交互作用对破碎率和未脱净率影响大,未脱净率低的较优组合是柔性齿直径为8mm,齿长为75mm,齿迹距为55mm的等齿迹距滚筒;破碎率小的较优组合是柔性齿直径为45mm,齿长为75mm,齿迹距为45mm的等齿迹距滚筒. |

| Abstract: | A flexible threshing roller was designed to reduce the demage or broken rice grain because of the more larger rigidity impacting force.To optimize its structure,related experiment about effects of its structural parameters including type of the roller opening or closing,diameter of the rolle,length of its threshing teeth and the distance of relative teeth on the threshing character was practised.single factor experimental results show the diameter and length of the threshing teeth was significant for the th... |
