摘要： 根据甘蔗尾部抗弯、抗压和抗冲击强度显著低于其他部位的特点，探讨了整秆式甘蔗收割机断尾机构的设计方案；分析其设计要求和工作机制，提出了3种断尾机构设计方案.通过ANSYS/ADAMS联合仿真分析比较其工作稳定性，证明防窜动式断尾机构合理可行，具有良好的通过性，上下跳动和左右窜动程度小，可以实现断尾功能。通过虚拟试验得到了防窜动式断尾机构的最优结构参数范围：上下断尾轮的中心距h取320 mm到330 mm，上下断尾元件的交错角度α取5°到10°.在带有防窜动式断尾机构的整秆式甘蔗收割机断尾机构试验台上，按照最优结构参数进行物理样机验证性试验.结果表明：该断尾机构合理可行，断尾率达到92.5%，理想断尾率达到87.5%。这可为整秆式甘蔗收割机断尾机构设计提供参考.
Abstract: Sucrose accounts for about 90% of the total amount of sugar in China. However, the mechanization degree and working efficiency on planting, harvesting and sugaring of sugarcane in China is far lower than western countries, and especially the problem of high impurity rate affecting the sugaring efficiency after sugarcane harvest is more serious. Because the tail of sugarcane is low in sugar, removing the tail of sugarcane in the harvest process can effectively improve the efficiency of sugaring.
As the mechanical strength of the tail is significantly lower than the middle and the base of sugarcane stalk, an idea on design of the tail-reasonable tailbreaking mechanism was designed.
Because the flexure strength, compressive strength and shock strength of the tail were significantly lower than any other part of the sugarcane, the design scheme of the tail-breaking mechanism on the whole stalk sugarcane harvester was discussed. Three kinds of tail-breaking mechanism were designed by analyzing the design requirements and working mechanism. Co-simulation analysis by ANSYS and ADAMS was employed to compare the difference among the three kinds of tail-breaking mechanism. 
The results showed that the anti-movement tail-breaking mechanism was proved to be reasonable and feasible, with better passing ability, and smaller degree of jumping up and down or running around. Besides, it also had good function of tail-breaking.
Optimal structure parameters for this anti-movement tail-breaking mechanism were obtained by virtual tests as follows: 320-330 mm of center distance between the top and bottom tail-breaking wheels, and 5-10 degree of stagger angle between the top and bottom tail-breaking elements. According to the optimal structural parameters, the physical prototype verification test was operated with the whole stalk sugarcane harvester with anti-movement tail-breaking mechanism. The results showed that, the tail-breaking mechanism was reasonably practicable with the tailbreaking rate of 92.5%, and the ideal tailbreaking rate could reach 87.5%. It can provide a reference for the design of tail-breaking mechanism for the whole stalk sugarcane harvester.
