摘　　要：针对甘蔗叶打捆作业时存在粉碎不匀、缠绕、阻塞等问题,结合甘蔗叶的物理特性,设计采用螺旋线排列结构参数可调的中垂刀+倾斜45°对称斜切刀式的中对称垂斜切式捡拾粉碎机构。利用Solidworks对其机构进行三维建模,并对该机构中的刀辊转速、离地高度、粉碎刀旋转方向及受力进行分析,通过运用有限元软件对粉碎刀进行模态应力分析,确定捡拾粉碎机构,进行样机制作。通过田间试验表明中对称垂斜切式粉碎机构,在不影响宿根生长的基础上,可实现甘蔗叶粉碎长度在≤15 cm的范围内,甘蔗叶捡拾率达到86.22%,粉碎合格率达到85.43%,工作效率达到0.16 hm^(2)/h,为甘蔗叶打捆机的优化设计提供参考。To address the problems of unevenness,entanglement,and blockage in the bundling operation of sugarcane leaves,this study proposes a design featuring a middle vertical cutter with adjustable spiral arrangement structure parameters and a middle symmetrical diagonal cutter with a 45°tilt,based on the physical characteristics of sugarcane leaves.Solidworks is used to conduct three-dimensional modeling of the mechanism,and the tool roll speed,height off the ground,grinding knife rotation direction,and force analysis of the mechanism were conducted using finite element software for grinding knife modal stress analysis.The prototype mechanism was produced.Field experiments showed that the symmetrical vertical and diagonal crushing mechanism achieved a sugarcane leaf crushing length within the range of≤15 cm,a sugarcane leaf picking rate of 86.22%,a qualified crushing rate of 85.43%,and a working efficiency of 0.16 hm^(2)/h without affecting the growth of long roots.These results provide a reference for the optimization design of sugarcane leaf baling machines.
