    摘要:

    以被動式傾斜波紋圓盤刀為研究對象，運(yùn)用速度瞬心法得出播種機(jī)前進(jìn)速度和切茬深度是切茬速度的主要影響因素。考察了播種機(jī)前進(jìn)速度和配重對圓盤刀工作性能主要指標(biāo)（切茬深度和牽引阻力）的影響。兩指標(biāo)兩因素正交田間試驗(yàn)結(jié)果表明，切茬深度和牽引阻力均隨兩因素增加而增大，配重是影響切茬深度的主要因素；當(dāng)配重達(dá)到一定值時，播種機(jī)前進(jìn)速度對切茬深度的影響比對牽引阻力的影響顯著。

    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 carried out for passive stubble-cutting disc with oblique ripples. The results showed that both stubble-cutting depth and draught resistance increased with the two factors, and pullback weight was the principal factor to stubble-cutting depth. When pullback weight on cutting disc reached a certain degree, influence of seeder advance speed on stubble-cutting depth was more prominent than that on draught resistance. 
