我国目前大批量生产的谷物联合收割机,均属传统式结构,用于收割我国北方粳稻,很难突破籽粒脱净与脱壳破碎这一关。而各省、地小批量试产的几种与拖拉机配套的轴流滚筒水稻收割机(例如珠江-2、军农-2、丰收-1等)又因动力小等原因,用来收割我省亩产千斤以上粳稻,仍存有效率低、质量差等问题。 At present, China’s large-scale grain combine harvester is a traditional structure, which is used for harvesting northern japonica rice in our country. It is difficult to break the gap between the grain removal and the crushing. In contrast, several small-scale trial production of various provinces and localities, such as the Pearl River -2, Junnong-2, Harvest-1, etc., supported by tractors, Production of more than kilograms of japonica rice, there are still low efficiency, poor quality and other issues.
