上海市农场局农机研究所近年内设计成功“KJ系列农田圆盘开沟机”(以下简称KJ系列开沟机),主要用于我国广大畦作区旱作物田的开沟作畦。KJ系列开沟机于1991年前后由江苏省常州南方农林机械厂及上海申光机械厂先后试制成功,并经多点大面积的耐久性考核,其中基本机型1KJ-35型于1992年初通过鉴定,投入了批量生产。 1KJ-35型(图1)主要配套36.8～44.1千瓦(50～60马力)拖拉机中动力输出轴转速为700～800转/分的机型(如上海-50、上海-504和江苏-50等);1KJ-35A型主要配套36.8～44.1千瓦拖拉机中
Shanghai Farm Bureau Institute of Agricultural Machinery successfully designed in recent years “KJ series of farm disc ditcher ” (hereinafter referred to as KJ series of ditching machine), mainly for China’s vast cropland for dry crop fields for ditching 畦. KJ series trencher was successfully trial-produced by the South Agricultural Machinery Factory in Changzhou, Jiangsu Province and Shanghai Shenguang Machinery Factory before and after 1991 and passed the multi-point large-scale durability test. The basic model 1KJ-35 type passed in early 1992 Identification, put into mass production. 1KJ-35 (Figure 1) The main supporting 36.8 ~ 44.1 kW (50 ~ 60 horsepower) tractor output shaft speed of 700 ~ 800 rev / min models (such as Shanghai -50, Shanghai -504 and Jiangsu -50, etc. ); 1KJ-35A-type main supporting 36.8 ~ 44.1 kilowatts tractor
