    摘要:

    對影響撥指鏈式扶蔗器扶起后倒伏角的設計參數(shù)：前進速度、下鏈輪轉速、扶蔗器導軌傾角和扶蔗器導軌偏角進行了室內試驗。通過四因素三水平正交試驗和單因素試驗，并利用數(shù)理統(tǒng)計方法建立了影響扶起后倒伏角的數(shù)學模型，探討了扶蔗器的運動參數(shù)和結構參數(shù)對扶起后倒伏角的影響規(guī)律，并優(yōu)化了設計參數(shù)。結果表明：4個設計參數(shù)對撥指鏈式扶蔗器的扶起后倒伏角具有顯著影響，參數(shù)最優(yōu)組合為：下鏈輪轉速與前進速度應符合關系式n=-1599.618v2m+1609.678vm，導軌傾角為60°，導軌偏角為

    Abstract:

    10°。A finger-chain type sugarcane-lifter was studied. The orthogonal and single experiments were conducted to study the following factors: advancing velocity vm, rotational speed of driven sprocket n, lateral-angle βof slideway and oblique-angle αof slideway. The mathematical models for the two evaluations index which contained lodging angle after lifting and different factors were constructed by using the method of mathematical statistics. And the parameters of the sugarcane-lifter were optimized. The results of experiments showed that these four factors had significant impact on lodging angle after lifting. The optimal parameters were as following: the function between rotational speed of driven sprocket n and advancing velocity vm was n=-1599.618v2m+1609.678vm, the obliqueangle equaled to 60° and the lateral-angle equaled to 10°. 
