水稻不同脱粒装置脱粒性能的对比试验研究

为了提高水稻联合收获机的工作效率,降低功耗,减轻清选负荷,自行研制了板齿和杆齿作为水稻脱粒的主要元件,分别与栅格凹板组成不同的脱粒分离装置,并对这两种脱粒分离装置进行了脱粒对比台架试验.试验结果表明,杆齿-栅格凹板脱粒分离装置在脱粒水稻时对茎秆的破碎程度轻、功耗低、脱出混合物中轻杂物含量少,能够有效地减轻清选负荷.

Contrast Testing Research of Rice Threshing Performance of Different Threshing Device

In order to improve the work of rice combine harvester efficiency,lower power consumption,reducing cleaning load,developed by the board tooth and tooth bar as the main components of rice threshing,respectively,with the grid of the threshing concave plates of different separation devices,and these two were threshing threshing and separating unit bench test comparison.The results show that the pole teeth-grid intaglio threshing rice threshing and separating device at the time of the broken stem level low powe...
