摘　　要：设计了3ZS-150型水稻中耕除草机。对除草部件结构参数进行理论分析,据此设计了苗间和行间除草部件。该机由插秧机底盘提供配套动力,设有软轴驱动式苗间弹齿式除草盘和旋转式行间耕耘锄,可一次完成苗间和行间除草作业。田间试验表明,当中耕深度31 mm、苗间除草盘转速186～190 r/min、机器前进速度为0.35m/s时,除草率为80.46%,伤秧率为4.76%。Based on force analysis of key weeding components,3ZS-150 paddy weeding-cultivating machine which could remove the weeds between seeding lines and inter-rows was designed.The machine motive power from the transplanter and equipped with the spring-tooth cutterhead、inter-row weeding hoe.The field performance testing showed that when the average cultivating depth was 31 mm,the cutterhead rotation speed was 186～190 r/min,and the forward velocity was 0.35 m/s,the average cleaning rate was 80.46%,the injury seedling rate was 4.76%.
