整秆式甘蔗收获机蔗叶分离机构设计与试验

为了进一步降低整秆式甘蔗收获机的含杂率,满足糖厂对机械化收割甘蔗的含杂率要求,结合甘蔗在蔗叶分离过程中的受力分析,对甘蔗起主要支撑作用的剥叶辊、输出辊及除杂辊进行布局安装,避开了蔗叶分布范围,以利于实现较高的除杂率。通过在试验平台上进行的正交试验研究,得出了该蔗叶分离机构的较优参数组合:刷片形状为20mm梳齿型,除杂辊与甘蔗交错深度0mm,除杂辊转速140 r/min。试验结果表明:此蔗叶分离机构具有较好的蔗叶分离效果,从而验证了蔗叶分离机构的可行性。

Design and Experiment on Sugarcane Leaf Separation Mechanism of Whole-stalk Sugarcane Harvester

In order to further reduce the trash content of the whole stalk sugarcane harvester , to meet the sugar-refinery requirements of the trash content of the whole sugarcane harvester , this article endeavors to analyze distribute and instal-lation the stripping roller , conveyor roller and cleaning roller which function as supporting role , with the help of sugar-cane ’ s force analysis when the sugarcane leaves were separated .The orthogonal experiment research tested on the experi-mental platform shows that the reasonable parameter groups of the separating roller were : the shape of the brush is the 20mm comb perforation, the interleaving depth between cleaning roller and sugarcane is 0mm, the rotation speed of the cleaning roller is 140r/min.The experiment results show that the mechanism is effective and feasible .
