链条拨秆式油菜分厢机的研制

摘要

The Chain-driving lever type machine was designed to resolve the problem of stalk dividing in rape harvesting,which had much difficulty in stalk dividing due to the across branches.Self-propelled walk chassis equipped with DC variable speed motor,while double power was used to achieve independent control of stalk dividing and walking.Then,acrylic material with arc-shaped structure was the critical working parts in stalk dividing,side expansion rollers were designed for sub-compartment forming.Tests showed that speed of 0.6m / s,angle of 60 °-70 ° for driving lever obliquity,chain speed of 1.1-1.2m/s,the effect of dividing stalk was better.It could achieve the stalk dividing operation for rape before mechanized harvesting.%针对油菜收获时因茎秆分枝交叉导致机收时难以分禾的实际问题,设计了一种链条拨杆式油菜分厢机,采用自走式行走底盘,配套直流变速电机做动力,采用双动力实现分禾行走独立控制,采用亚克力材质阿基米德弧线形结构设计分禾关键工作部件,设计被动式分禾转动轮实现分厢定型.试验表明,在行驶速度为0.6 m/s,拨杆上升倾角60°～70°,分禾链条线速度为1.1～1.2 m/s分禾效果较好,能够实现油菜机械化收获前的分厢作业.
