Abstract: 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 hm2/h without affecting the growth of long roots. These results provide a reference for the optimization design of sugarcane leaf baling machines.
