    摘要:

    針對滑刀式開溝器設(shè)計及制造隨意性強(qiáng)、應(yīng)用范圍不夠廣泛的問題，設(shè)計了12種具有不同厚度和滑切角的滑刀式開溝器，并在實驗室內(nèi)通過土槽和壓力機(jī)進(jìn)行混合型正交試驗，試驗指標(biāo)為牽引阻力和正壓力。試驗結(jié)果表明，滑切角是影響滑刀式開溝器作業(yè)性能的主要因素，刃口曲線終點(diǎn)的滑切角θA在35°～55°范圍內(nèi)時開溝器具有較好的綜合性能。

    Abstract:

    Twelve kinds of sliding knife furrow openner with different thickness and sliding cutting angle were designed in view of this issue about the casualness in the design and manufacture and limited application. Mixed type orthogonal test was carried out through soil bin and press in the laboratory with test index of traction resistance and vertical pressure. The test results showed that the sliding cutting angle was the main factor effecting its working performance, and the furrow opener possessed better comprehensive performance when its sliding cutting angle in the edge curve terminal point was in the range of 35°～55°. 
