全膜双垄沟地膜捡拾机的设计

为了解决地膜污染问题,通过对国内外地膜捡拾机的研究和借鉴,研制出全膜双垄沟地膜捡拾机。运用SolidWorks motion功能仿真弹齿M点的运动轨迹和X方向线性速度,得出收膜滚筒的转速为80 r·min~(-1),通过设计计算和考虑其它因素得出入土角为25°;在此基础上增加反向推膜机构,对集膜滚筒机械进行改进优化并做出样机。实验表明,该样机作业生产率为0.4~0.6 hm~2·h~(-1),地膜捡拾率为90%,使用可靠性为98%,工作效率高,制造成本低,适应性强。

Design of the film picking machine for double furrows

In order to solve the problem of plastic film pollution,through the research and reference for the film picking machine at home and abroad,developed the film packingrnachine for whole double furrows.Using the SolidWorks motion function simulated the movement track of the elastic claw M point and the linear velocity of X direction,obtained that the rotation rate was 80 r·min-1 for the film roller.Through the design and calculation and considered other factors obtained the soil penetration angle was 25°.Finally carried out the improvement and potimization for the key parts of the prototype machine.The experiments showed that:The prototype working productivity was 0.4 ～ 0.6 hm2· h-1,picking plastic film rate was 90％,and the using reliability was 98％,with high work efficiency,low manufacturing cost and strong adaptability.
