摘　　要：为探索甘蔗扶起的效果,采用3D打印技术,使用高分子材料,添加了摩擦因数因素,设计并制作出一新型扶蔗器。通过正交试验和单因素试验,探明了甘蔗扶起过程的影响规律。结果表明:扶蔗器转速对甘蔗扶起效果影响最大,其次是滚筒直径。最佳方案为:当材料PETG、摩擦因数0.65、直径150 mm、螺距160 mm、圆锥角18°、前进速度0.36 m/s、转速150 r/min时,扶起时间为3.3~6 s,扶蔗平稳,可以实现高效作业。In order to explore the effect of sugarcane lifting,a new type sugarcane lifter was designed with 3D printing technology,adding polymer material and friction coefficient factor.Through orthogonal test and single factor test,the influence law of sugarcane lifting process was proved.The results showed that:The speed of sugarcane lifter had the greatest influence on the lifting effect of sugarcane,followed by roller diameter.The best scheme was PETG for material,friction coefficient 0.65,diameter 150 mm,pitch 160 mm,cone angle 18°,forward speed 0.36 m/s and speed 150 r/min.The lifting time was 3.3-6 s,and the lifting time was stable.Efficient operations can be achieved.
