| 摘 要： | 以被动式倾斜波纹圆盘刀为研究对象,运用速度瞬心法得出播种机前进速度和切茬深度是切茬速度的主要影响因素。考察了播种机前进速度和配重对圆盘刀工作性能主要指标(切茬深度和牵引阻力)的影响。两指标两因素正交田间试验结果表明,切茬深度和牵引阻力均随两因素增加而增大,配重是影响切茬深度的主要因素;当配重达到一定值时,播种机前进速度对切茬深度的影响比对牵引阻力的影响显著。 |
| 关 键 词： | 倾斜波纹圆盘刀 切茬深度 牵引阻力 配重 速度瞬心法 试验 |

| Abstract: | Passive stubble-cutting disc with oblique ripple was taken as the object.Based on the method of velocity instantaneous centre,seeder advance speed and in-soil depth of cutting disc were chosen as the main factors affecting stubble-cutting speed.Stubble-cutting depth and draught resistance were the indicators of cutting disc performance experiment,while seeder advance speed and weight assigned to the cutting disc were the experimental factors.Two-indicator and two-factor orthogonal field experiment was carri... |
