1、编号:毕业设计说明书题目:水草清理装置水下机构的设计摘要针对河道、水塘等水域具有航道窄、面积小,一般的大型水草收割机难以实现水草收割的现状,本文设计了一种结构紧凑,机构传动平稳,效率高,适合在中小尺度水域作业的小型水草收割机。论文概述了水草收割机的发展背景、研究现状及分类;完成了水草收割机水下部分的机构设计,主要包括清除机构和定位机构;阐述了前置往复式切割器和旋转式升降台的总体设计方案、工作原理、参数计算以及试验校核;同时,为了防止二次污染,本文还另外设计了水草回收装置,通过传送带将水草运回船体;按照任务要求完成了装置总装图与各主要零部件图的绘制;最后,通过Solid
2、works软件的动画仿真验证了机构设计的合理性。结果表明:所设计的小型水草收割机具有结构合理、紧凑,适应性强,切割效率高等优点。这种新型的水草收割机可在水下实现切割,捡拾、传送一体化连续作业方式,能够达到清除泛滥的水草,净化水质的目的。总的来说,是一种较为理想的水草收获机具。关键词:小型水草收割机;水下机构设计;动画仿真AbstractWaterssuchasrivers,pondsaregenerallywithnarrowwaterwayandsmallarea,sogenerallargeaquaticweedharvesterscanhardlyharvest
