背景技术Background technique
目前，我国甘蔗种植面积广泛，年产量位居世界第三位。甘蔗收获是甘蔗生产中最重要的环节，现有的甘蔗收获机物流装置存在堵塞或含杂率较高等常见现象，堵塞的一般过程集中在刀盘切割时喂入输送辊之前以及剥叶阶段，含杂率较高主要由受剥叶过程影响。At present, my country's sugarcane planting area is extensive, and its annual output ranks third in the world. Sugarcane harvesting is the most important link in sugarcane production. The existing logistics devices of sugarcane harvesters have common phenomena such as clogging or high impurity content. The general process of clogging is concentrated before feeding the conveyor roller during cutting by the cutter head and at the leaf stripping stage. The higher impurity content is mainly affected by the leaf stripping process.
现有的甘蔗收获机的剥叶轮叶片一般采用直线形或螺旋形，虽然一定的螺旋角对增强剥叶轮对甘蔗的打击效果、剥开紧包甘蔗蔗叶比较有利，但是过大的螺旋角会增加甘蔗伤皮率。The stripping impeller blades of existing sugarcane harvesters are generally linear or helical. Although a certain helix angle is more favorable for enhancing the striking effect of the stripping impeller on sugarcane and peeling off tightly packed sugarcane leaves, an excessive helix angle will Increases sugarcane damage rate.
