    摘要:

    為了確定兩段螺旋式扶起機構(gòu)的結(jié)構(gòu)參數(shù)，運用虛擬技術(shù)對該機構(gòu)和甘蔗扶起過程進行了運動學(xué)仿真，設(shè)計了兩段螺旋式扶起機構(gòu)樣機，在高速攝影的環(huán)境下進行了甘蔗扶起性能試驗，獲得扶起機構(gòu)對甘蔗的作用及影響規(guī)律。結(jié)果表明：扶起機構(gòu)適用于側(cè)向倒伏角為45°~165°的甘蔗；速比為0.59，揀拾段安裝角為5°，輸送段安裝角為60°時，扶起甘蔗效果最好。

    Abstract:

    Based on dynamic simulation, two sections spiral sugarcanes lifter was designed and a sample machine was made. The effect rules of the two sections spiral sugarcane lifter were got through experimental test associated with the application of high-frequency photograph technology. The experiment results showed that, the two sections spiral sugarcane lifter worked well with lodge-angle of 45°~165°. Furthermore, the lifter worked best when the parameter of movement was 0.59, and the picking angle of setting was 5°, and the transportation angle of setting was 60°.
