不同倒伏状态甘蔗扶起过程的试验

Experiments of Lifting Process for the Lodged Sugarcane

设计了分蔗靴-螺旋滚筒-拨指链组合式扶蔗器.将甘蔗按照倒伏状态分类,与拨指链式扶蔗器一起进行实验室对比扶蔗试验,研究扶蔗器对不同倒伏状态甘蔗的扶起效果.结果表明:对于倒伏角小于30°、侧偏角大于15°的严重倒伏甘蔗,组合式扶蔗器扶起后甘蔗的倒伏角为61.4～75.5°,效果明显优于拨指链式扶蔗器;对于倒伏角大于30°、侧偏角大于15°的一般倒伏甘蔗,2种扶蔗器的扶蔗效果一致,扶起后甘蔗的倒伏角为69.4～76.8°.

The divider-spiral roller-finger chain combined sugarcane-lifter was designed to study the lifting effect for various lodged sugarcane. In accordance with the classification for different lodged status of sugarcane, the comparison experiments were done for sugarcane lifting with finger-chain type and divider-spi- ral roller-finger chain combined sugarcane-lifters. The experimental results showed that the lifting effect of combined sugarcane-lifter was better than that of the finger-chain type sugarcane-lifter for heavily sugarcane （the lodged angle was less than 30° and the side-angle was greater than 15°） ,and the angle after lifting general lodged lodged lodged was 61.4 -75.5°. Meanwhile, the two devices could perform a good lifting effect for the sugarcane （the lodged angle was greater than 30° and the side-angle was greater than 15°） ,and the lodged angle after lifting was 69.4 -76.8°.
