Virtual Simulation Analysis And Design On Tail-breaking Mechanism Of Whole-stalk Sugarcane Harvester

Mechanization of sugarcane harvesting is very important to increase the sugar production. And the sugar of post-harvest sugarcane is a necessary factor too. In China, the whole-stalk sugarcane harvester has become the main sugarcane harvester. It’s working process involves cane-holding, root-cutting, leaves-peeling, tail-breaking, transportation and packing, the effect of the leaves-peeling and tail-breaking is removing the part which has lower sugar. Therefore, tail-breaking mechanism is important for the sugar production. Currently, our tail-breaking mechanism has some problems that it is difficult to control the length of tail for cutting.In summary, it is necessary to design a better one.By studying the mechanical properties and Brix of different parts of the sugarcane, we know that the mechanical properties of the tail is lower than others. According to this basis, a new tail-breaking mechanism is designed. By building model, dynamic simulation and virtual analysis, the better one of the three designations is selected. In order to parameter optimization, virtual orthogonal tests have been performed by simulation software called ADAMS. It is proved that the best optimal parameters of the structure is that:the distance of the central axis of the tail-breaking wheels is330mm, interleaved angle between the tail-breaking element is7.5°, the elastic modulus of the tail-breaking element is11.76MPa, the rotate speed of the tail-breaking wheel is348r/min. Finally, by the physical prototype testing, the tail-breaking rate under best optimal parameters stands at90%, and the ideal rate is75%.
