    摘要:

    為了解決整稈式甘蔗收獲機(jī)剝?nèi)~過程由于多根喂入和帶尾部剝?nèi)~造成含雜率和折斷率高的問題,，設(shè)計(jì)了彈性齒滾筒式甘蔗剝?nèi)~裝置,，闡述了喂入,、輸出滾筒和剝?nèi)~滾筒的結(jié)構(gòu)和剝?nèi)~原理,，確定了主要部件的結(jié)構(gòu)參數(shù),。通過四因素三水平正交試驗(yàn)研究剝?nèi)~元件彈性齒角度、剝?nèi)~滾筒中心距,、剝?nèi)~滾筒轉(zhuǎn)速和喂入,、輸出滾筒轉(zhuǎn)速等4個(gè)因素對含雜率、莖稈折斷率和斷尾率的影響和最優(yōu)參數(shù)組合,，在此基礎(chǔ)上進(jìn)行綜合剝?nèi)~試驗(yàn),。結(jié)果表明，最優(yōu)參數(shù)組合為：剝?nèi)~元件彈性齒角度90°,、剝?nèi)~滾筒中心距310 mm,、剝?nèi)~滾筒轉(zhuǎn)速700 r/min和喂入、輸出滾筒轉(zhuǎn)速150 r/min,。甘蔗單根連續(xù)喂入319.19 kg,，含雜率為1.56%、莖稈折斷率為20.45%,、斷尾率為65.97%,；3~5根連續(xù)喂入274.52 kg，相應(yīng)的剝?nèi)~指標(biāo)依次為2.38%,、25.93%和75.59%,。

    Abstract:

    In order to solve the problem of high impurity rate and stalk broken rate existing in the leaf-stripping process of the whole stalk sugarcane combine harvester, the elastic dentation roller type leaf-stripping test device was designed. The main structure of feeding roller, output roller and leaf-stripping roller and the principle of leaf-stripping were introduced. The structure parameters of main parts were determined. The orthogonal experiments were conducted to study the influence between the following four factors, the installation angle of leaf-stripping component, the center distance between the top and bottom leaf-stripping rollers, rotate speed of leaf-stripping rollers and rotate speed of feeding and output rollers, and the following three indexes on leaf-stripping quality, impurity rate, stalk broken rate and top broken rate. The result showed that the optimal parameters were as following: the installation angle of leaf-stripping component was 90°, the center distance between the top and bottom leaf-stripping rollers was 310 mm, rotate speed of leaf-stripping rollers equaled 700 r/min and rotate speed of feeding and output rollers equaled 150 r/min. In the meantime, when the total weight of 319.19kg sugarcane was fed continuously into the device in the way of single stalk, the impurity rate, stalk broken rate and top broken rate reached to 1.56%, 20.45% and 65.97%. Otherwise, when the total weight of 274.52 kg sugarcane was fed continuously into the device in the way of three to five stalks simultaneously, the final result was 2.38%, 25.93% and 75.59% respectively. 
