4LT-A型错行作业挖掘甜菜联合收获机研制与试验

针对中国北方甜菜主产区机械化收获水平低下、缺乏先进适用的国产甜菜联合收获技术装备问题,研制了一种可自动对行纠偏的错行作业挖掘型甜菜联合收获机。该机配套50 k W以上拖拉机,一次作业2行,完成打叶切顶、挖掘输送、清杂装卸作业,纯生产率大于0.3 hm2/h,适宜种植形式为单垄单行、种植面积适中、对象为农场和种植大户收获使用。田间试验表明,该机收获质量良好,块根含杂率小于2%,块根折断率小于3.5%,切顶合格率大于85%,块根损失率小于4%,各项指标达到国家规定标准,符合甜菜收获要求。该研究攻克的自动对行纠偏、仿形切顶、低损挖掘等技术为推进主产区甜菜联合收获技术装备的自主研发提供参考。...

Sugar beet was the most important source of sugar in the sugar industry, with the sugar amounting to about 17% of China＇s total sugar production. As a seasonal operation, sugar beet harvesting in China was still mainly manual work, having the problems of high labor intensity, low efficiency, great harvest losses and huge occupation of farming and so on, which constrained the further development of the sugar beet industry. Mechanized harvesting was the inevitable development trend of sugar beet harvest. Beet harvest mechanization development had lagged in our country for a long time. And we were lack of a thorough system research about sugar beet harvest mechanization technology, especially the advanced combine technology. The current domestic sugar beet harvest
