摘　　要：为了达到玉米行间除草的目的,设计了能够定位玉米秧苗位置、并且躲避玉米秧苗的行间除草装置,其中包含采用65Mn碳素弹簧钢丝设计的梳齿式除草执行部件,采用行程开关设计的玉米秧苗定位部件,以及以伺服电机为主的驱动部件。2019年6月,国家农机具质检中心对该装置进行检测,检测结果表明其平均除草率为95.1%,平均伤苗率为1%。方差检验的结果显示,株距与梳齿入土深度均对除草率具有显著影响,同时株距对于伤苗率也具有显著影响。本文研究结果可以为旱田行间除草装置的设计提供有益参考。In order to achieve the goal of maize inter-row weeding,this study designed the inter-row weeding device which can locate the position and avoid the injury of maize seedlings.This device includes the comb type weeding executing part designed with 65 manganese carbon spring steel wire,the maize seedling positioning part designed with travel switch and the driving part mainly based on servo motor.This inter-row weeding device was tested in June 2019 by the National Agricultural Machinery Quality Inspection Center.The test results show that the average weeding rate was 95.1%,and the average seedling injury rate was 1%.Variance test results show that the plant spacing and the stabbing depth have a significant impact on the weeding rate,and the plant spacing also has a significant impact on the seedling injury rate.The results of this study can provide useful reference for the design of inter-row weeding device in dry field.
