曲柄摇杆式残地膜捡拾机构研究

Crank-rocker Mechanism for Collecting Plastic Film

针对目前残膜捡拾机构性能不可靠,造成残膜收净率较低的问题,提出一种曲柄摇杆式残地膜捡拾机构,建立机构几何与数学模型,对所设计机构的工作机理进行仿真、分析与优化,达到了捡拾与卸膜的工作要求。大田试验表明,机具的工作效率大于0.4 hm2/h,残膜回收率达到88.5%,工作过程中基本未出现缠绕问题。

Unstable operation performance of mechanism for collecting plastic film results in low rate of collecting used plastic film. A crank-rocker mechanism for collecting plastic film was presented. The geometry and mathematic models of the proposed machine were built for simulating,analyzing and optimizing the work mechanism,then the working requirement for picking-up and removing the used plastic film was met. Field experiment showed that,the working efficiency of machine was higher than0. 4 hm2/ h,and the rate of collecting used plastic film was 88. 5%. Basically,no operation wound problems were found during the whole experiment.
