Simulation and experiments of two-stage spiral sugarcane picking-up mechanism

To improve the picking-up ratio of sugarcane in hillside area, design of two-stage spiral sugarcane picking-up machine was brought up in this paper. Computer model was established and applied for simulation of the virtual prototype. Further more, the structure of the picking-up section was confirmed, and the athletics and speed equations of the two-stage spiral sugarcane picking-up machine were constructed, and the athletics condition of lifting sugarcane was established. The results of the sample machine showed that, the ratio of success picking-up was 20%, 90% and 100% respectively when the lodging angle was less than 30%, between 30° and 60° and at 90° side lodging. It was 50%, 10% and 0 respectively when the lodging angle was between 90° and 120°, between 120° and 150° and between 150° and 180°.
