【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。更多还原

【Abstract】 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.更多还原
