3ZS-150型水稻中耕除草机设计与试验

摘要

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% .%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0.35 m/s时,除草率为80.46%,伤秧率为4.76%.
