为改变传统杂交水稻制种中不育系和恢复系规则化种植,分期收获,效率低,劳动强度大,授粉不均匀,种子质量、产量低的现状,在现有工程化混播制种中急需高效的机械化分选设备。该文通过试验研究的手段,对所设计的窝眼型孔分选机分选筒的运动参数及结构参数进行了研究。结果表明:针对现有不育系籽粒长度不超过5.8mm,恢复系不小于12mm时,其分选筒外径设计为130mm,分选筒转速为30r/min,窝眼孔径为7mm,孔深为3mm情况下,能够杂交水稻种子纯度要求的分选效果。该分选机的设计,为解决工程化混播制种中杂交水稻种子不育系与恢复系的分选、清选提供了基础保障。

To change the situation of inefficient, labor intensive, uneven pollination, and low seed quality and yield of hybrid rice seed production when following the traditional rules of male sterile lines and restorer lines planting regularly, a kind of efficient mechanized sorting equipment is urgently needed in the existing engineered mixture sowing seed production. In this paper, experimental research methods were adopted to research the kinematic and structure parameters of the separation tube of sorting machine. The results show that when the length of the male sterile lines is less than 5.8 mm,...
