针对贵州省铜仁市植烟区膜后打孔投苗移栽方式存在的烟苗根部覆土不足、苗株周围易长草问题,设计了一款适合于铜仁市植烟区烟叶生产的乘坐式垄上破膜覆土一体机.该机由增程式发电机、铅酸电池组、行走装置、取土运土装置、破膜覆土装置、控制面板、机架及驾驶位等组成.利用Solidworks软件建立了双曲柄多连杆鸭嘴破膜覆土机构虚拟样机模型,经模型简化导入ADAMS中进行仿真分析,得到其运动轨迹和X、Y方向位移与时间变化曲线.结果表明,设计的双曲柄多连杆鸭嘴破膜覆土机构满足 55 cm定株距破膜和作业效率 0.067 hm2/h的要求,验证了其结构选择和参数设计的合理性.该机能够代替人工膜上覆土作业、降低作业成本、提高覆土效率,具有推广使用价值.
Design and simulation of integrated machine for breaking film and covering soil on ridge
In order to solve problems of insufficient soil cover on root of tobacco seedlings and grasses grow easily around seedlings in Tongren tobacco-producing area by punching holes and transplanting seedlings after film,an integrated machine for breaking film and soil covering on ridging was designed for tobacco production in Tongren tobacco-producing area.The machine consisted of extended range generator,lead-acid battery,walking device,taking and moving soil device,breaking film and covering soil device,control panel,frame and driver's seat.The virtual prototype model of double-crank multi-link duck-bill breaking film and covering soil mechanism was established by Solidworks software.The model was simplified and imported into ADAMS for simulation analysis,and motion trajectory,displacement and time change curves in X and Y directions were obtained.Results showed that designed double-crank multi-link duck-bill breaking film and covering soil mechanism could meet requirements of 55 cm fixed plant distance breaking film and 0.067 hm2/h opera-tion efficiency,which verified rationality of structure selection and parameter design.The machine could replace operation of artificial film covering soil,reduce labor and cost,improve efficiency of soil covering,and had value of popularization and use.
