| 摘要: |
| 针对采用圆盘式开沟器的小麦免耕播种机提出一种以缓冲作用强、易于调整为特点的垂直叉架式开沟器单体，对其空间运动进行了计算分析；对安装在同一梁上的两下悬挂点与具有可调范围的开沟器安装位置之间可能发生的冲突问题进行了分析，并给出了确定两下悬挂点间距的计算公式。计算和生产验证结果均表明，设计方案可行，计算公式可用。 |

| Abstract: |
| A vertically mounted fork-type opener unit,characterized by easy adjustingand stronger cushioning effect,for no-tillage wheat drill with disc openers is suggestedafter calculating and analyzing its spacial motion. The interference problems, which willprobably occur when the position parameters of the hitch points and the opener mounting points are irrationally selected,are analyzed. Formulas to calculate the space of twolower hitch points are developed. The feasibility of the design and the accuracy of theformulas are proven through calculations and field tests. |
