摘　　要：为解决水田的除草问题,增加现有机具的作业功能,该文在步进式插秧机底盘结构的基础上,研制了一种步进式水田中耕除草机。该机由步进式插秧机底盘提供动力,主要由机架、传动系统、仿形及耕深调节机构以及复合式除草部件指辊和刀辊等组成,可实现对杂草的拉拔和埋压。田间试验结果表明:该机配备复合式除草部件、工作速度为0.5m/s、除草深度为50mm时,行间除草率为83.7%,伤苗率为4.1%,可在草量多、杂草高的水田中进行有效除草。In order to solve the problem of mechanical weeding in paddy field and enhance the function of the exiting agricultural machine, a marching type inter-cultivating weeder was designed and tested in the paddy field by refitting a marching-type transplanter in this study. The designed machine was powered with the chassis of a marching type transplanter and composed of frame, power transmission system, mechanism of profiling and depth control and complex weeder including finger roller and blade roller which realized functions of pulling and bury-pressing on weeds during operation. Results of the field experiment showed that under the conditions that the forward velocity of the weeding machine was equipped with complex weeder 0.5 m/s and the weeding depth 50 mm, the cleaning rate was 83.7% and the injury rate of rice seedlings was 4.1%, and work effectively in paddy fields with large and high weeds.
