秸秆打捆机结构改进及仿真分析

Structural Improvement and Simulation Analysis of Straw Baler

我国甘蔗叶秸秆资源极其丰富,是一种宝贵的生物资源。甘蔗叶秸秆变废为宝,化害为利处理,已成为社会亟待解决的问题。实现甘蔗叶秸秆资源化利用,关键在于解决甘蔗叶秸秆如何高效回收。目前使用的秸秆打捆机会出现喂入口堵塞、卷捆不畅等问题。为此,通过虚拟样机技术对目前使用的秸秆打捆机进行结构改进和仿真分析实验,应用SolidWorks软件建立改进前和改进后打捆机的三维实体模型,再应用ANSYS和ADAMS软件对打捆机整机进行仿真分析。通过对改进前和改进后两款打捆机进行力学分析和仿真实验,结果表明:打捆机喂入机构增加喂入对辊和碾压对辊,可大幅提升打捆机的喂入能力;卷捆室钢辊优化排列和钢辊表面结构优化可大幅提升卷捆室的卷捆能力,一定程度上解决打捆机喂入口堵塞、打捆不畅等问题,为秸秆打捆机后续创新设计提供理论支持。

China’s sugar cane leaf straw resources are extremely rich and are a valuable biological resource. Sugarcane leaf stalks are turned into waste and turned into harms, which has become an urgent problem for the society. The key to realize the resource utilization of sugarcane leaf straw is to solve how to efficiently recycle sugarcane leaf straw. At present, straw bundling opportunities may cause problems such as blocked feed inlets, and unreliable rolls. Therefore, this study uses virtual prototype technology to carry out structural improvement and simulation analysis experiments on sugarcane leaf straw balers. The SolidWorks software was used to establish a three-dimensional solid model of the baler before and after improvement, and then ANSYS and ADAMS software were used to simulate and analyze the whole machine of the baler. By performing mechanical analysis and simulation experiments on the two balers before and after the improvement, the simulation results are obtained and analyzed. The baler’s feeding mechanism can increase the feeding rollers and the rollers, which can greatly improve the baler. The optimal arrangement of the steel rolls in the bundling chamber and the optimization of the surface structure of the steel rolls can greatly improve the bundling capability of the bundling chamber, which can solve the problems such as blockage of the feeding inlet of the baler and poor packing. Provide theoretical support for the subsequent innovative design of straw baler.
