    摘要:

    設計了一種由錐形螺旋滾筒和撥指鏈組成的組合式扶起裝置,并在土槽中進行了試驗研究,。以扶起合格率為試驗指標,,對甘蔗倒伏狀態(tài)、螺旋滾筒轉速、甘蔗與滾筒中心距離和前進速度為因素進行正交試驗。在得出優(yōu)化組合后,再分別進行滾筒軸線與地面夾角,、滾筒葉片螺距和滾筒轉速等因素的單因素試驗,以及滾筒轉速和前進速度的雙因素試驗,。通過高速攝影分析了扶起過程,。試驗結果表明,在最優(yōu)參數組合下,,組合式扶起裝置對嚴重倒伏甘蔗的扶起合格率達到90%,。

    Abstract:

    In order to lift severely lodging sugarcane in harvesting, the combined-lifter composed of spiral roller and chainlifter was designed, which was experimented on the vehicle of soil. The orthogonal experiments were conducted to study the following factors: the state, rotational speed of spiral roller, distance between sugarcane and spiral roller center and advancing velocity. According to the best combination of orthogonal test, the single experiments were conducted to study the following factors: the angle between the cylinder axis and ground, the blade pitch of helical spiral roller and rotational speed of spiral roller. The double experiments were conducted with the rotational speed and advancing velocity. High-speed photography experiments were conducted to analyze the process of lifting. In the optimal parameters, the results showed that eligible rate of lifting was up to 90% by the combined-lifter.
