窄幅深耕犁翻土覆盖性能的初探

通过“埋块试验”探讨了犁体宽深比和耕深对翻土覆盖性能的影响,证明了窄幅深耕犁的翻土覆盖性能能满足农艺要求。发现犁的宽深比还影响土垡在行驶方向上的位移距离,用窄幅深耕犁时土垡在行驶方向上的位移距离明显小于普通铧式犁,这很可能是窄幅深耕犁比阻降低的主要因素之一。

Study on the Turning and Mulching Mechanism of The Furrow Slice in Narrow Deep Plow

Through a series of experiments in which a number of little humored wood blocks were buried in the testing field (in order to determine the displacement of the furrow slices), the effects of the plowing depth and the ratio of the depth to width on the slicesoe turning and mulching rnachanism in plowing were examined. It was demonstrated that the slice turning and mulching results is proper for the agrinomy requirements and that the slice displacement in travel direction in the plowing experiments was influenced by the ratio mentioned above. Further more, it was found that this displacement, for small digger plow is smaller than that for common share plow. Moreover, this displacement may be a major factor that affects the plowing resistances.
