为解决因农药除草实施过量药剂,残留量过高,现有机械除草过程中作物苗间与秧苗附近杂草较难铲除、伤苗严重以及除净率低等问题,研制出与拖拉机配套使用的3ZC型中耕除草机。该机在玉米、大豆等作物中耕作业过程中能完成苗间松土、除草、起垄和培土等作业。论述了3ZC型中耕除草机的结构、工作原理及关键部件设计。田间试验表明,该机用于玉米行间杂草除净率≥98%,伤苗率≤3%,其他各项技术性能指标均符合设计标准,可满足旱田作物中耕管理作业的农艺要求。
In order to solve the problems of pesticide herbicide such as overdosage, excessive residues, weeds in the existing mechanical seedling and seedling near the existing machinery weeding process, serious injury wounds and low net removal rates, the invention has been developed for use with tractors 3ZC cultivator weeding machine. The aircraft in corn, soybeans and other crops in the process of cultivating seedlings to complete the soil loose, weeding, Ridge and earthwork and other operations. The structure, working principle and key components design of 3ZC type cultivator are discussed. Field tests showed that the machine was used in the weed removal rate of corn ≥ 98%, injury seedling rate ≤ 3%, and other technical performance indicators are in line with design standards to meet the requirements of field cultivation of agricultural management of agricultural crops.
