我国自行研制成功的为130、160马力轮式拖拉机配套的8种机具,已由国家科委委托机械部农机局与农牧渔业部农垦局主持,于1985年11月通过国家级新产品鉴定。这8种农机具是(见本刊今年第二期封二、封三):1LF—445悬挂翻转四铧犁;1LT—445悬挂调幅四铧犁;1LBT—445半悬挂调幅四铧犁;1BZK—3.3(3.9)重型圆盘耙;1SD—3.0深松联合耕作机;1ZL—4.2联合整地机;3ZXQ—1091旋转锄式全面中耕机;3ZF—12(16)中耕追肥机。这些机具是由中国农机院负责,有关省、市农机厂、农机所参加共同研制的。经四年多的试验研究和大面积生产考核,证明能满足东北、西北地区国营农场耕、整、深松、中耕等作业的农艺要求,能实现高速、高效、节能、优质作业,在产品结构和性能上达
Our country successfully developed eight kinds of tools for 130,160 horsepower wheeled tractors have been entrusted by the State Science and Technology Commission Machinery Bureau Agricultural Bureau and the Ministry of Agriculture, Animal Husbandry and Fisheries Bureau Reclamation Bureau, in November 1985 passed the national appraisal of new products. The 8 kinds of agricultural machinery is (see the second edition of this year, Feng two, seal three): 1LF-445 hanging flip four plow; 1LT-445 hanging amplitude modulation four plow; 1LBT-445 semi-suspended amplitude modulation four plow; 1BZK -3.3 (3.9) heavy disk harrow; 1SD-3.0 deep loose combined tillage machine; 1ZL-4.2 joint earthmoving machine; 3ZXQ-1091 rotary hoe full cultivator; 3ZF-12 (16) cultivator top-dressing fertilizer machine. These machines are responsible for the China Agricultural Machinery Institute, the relevant provincial and municipal agricultural machinery plant, agricultural machinery to participate in jointly developed. After more than four years of experimental research and large-scale production examination, it has been proved that it can meet the agronomic requirements of farming, whole plantation, deep-plowing and mid-tillage farming in the northeastern and northwestern regions, and can achieve high-speed, high efficiency, energy saving and high quality operation. And performance up
