摘要
免耕播种机地轮滑移造成排种器漏播,影响播种质量。为此提出了一种行星啮合式防滑地轮机构。在对其进行结构与受力分析的基础上,研究了影响地轮性能的因素。对不同型式的地轮在已耕和免耕土壤中进行对比试验表明,行星啮合式防滑工作稳定且具有较小的滑移率。
Sliding of ground wheel will cause seed missing and quality decreasing. In order to solve the problem, a planetary geared ground wheel for no-tillage planter was developed. On the basis of analysis of structure and force of the wheel, the factors affecting performance of ground wheel were found. The experiments were conducted with different kinds of ground wheels in tillage and no-tillage soil. It was found from the comparative experiments that the anti-sliding ground wheel had minor sliding rate and steady performance.
