4YL-1A型玉米联合收获机是河南省郑州市农机研究所和郑州农具厂继推出4YL-1型玉米收获机(秸秆还田型)之后,为了充分利用玉米秸秆资源,满足畜牧业发展的需要而研制的粮饲兼收型玉米联合收获机。该机与18.3～22.0kW拖拉机配套使用,可一次完成玉米摘穗、果穗装箱、秸秆切碎装箱集堆等项作业。适宜小型畜牧场和“养殖小区”以机械化作业替代人工或半机械化的作业方式,实现玉米收获、秸秆青贮或回收后的综合利用。通过两年的研制试验和2000年秋季在内蒙古赤诚农场的 4YL-1A corn combine harvester is Zhengzhou Agricultural Machinery Research Institute of Zhengzhou City and Zhengzhou farm tools following the introduction of 4YL-1 corn harvester (straw-type), in order to make full use of corn stalks resources to meet the needs of the development of animal husbandry The development of food and corn-type corn combine harvester. The machine and 18.3 ~ 22.0kW supporting the use of tractors, can complete a corn harvest ears, ears packing, straw shredding packing pile and other operations. Suitable for small livestock farms and “farming community ” to mechanized operations instead of manual or semi-mechanized mode of operation to achieve corn harvest, straw silage or comprehensive utilization after recovery. After two years of research and development trials and in the fall of 2000, Chengsheng Farm in Inner Mongolia
