Experimental study on influencing factors of lifting quality for push-over-type sugarcane harvester

To optimize operational parameters of push-over type sugarcane harvester, a test device of sugarcane lifter was designed. The main influencing factors for sugarcane lifting were disclosed through orthogonal experiment and single factor experiment. The results showed that the effect of rotating speed of spiral support device on lifting efficiency was significant, followed by that of forward speed of the lifter. Furthermore, the interaction of the revolving and forward speeds on lifting attitude angle was dramatically. The optimal parameters were as followed: the harvester rotation was 120 r/min, forward speed of the lifter was 0.21 m/s, setting angle of conveying section was 50°, setting angle of picking section was 5°. Under these conditions, the lifting quality was best with 45°-135°of slide angle and 50.68° to 68.87° of lifting attitude angle, which met the need of sugarcane harvester operation.
