  毕业设计说明书中文摘要 牧草切根机的设计——机架设计 摘 要 针对典型草场板结严重且横走根茎错节致使自繁促生能力下降等问题,设 计了牧草切根机具。该机采用凸轮机构驱动直切刀对牧草进行垂直切根,减小了切根 阻力和切缝宽度,通过简单操作可实现对不同间距、不同深度牧草进行切根作业,从 而达到切断亚表层下的横走根茎、改良草地,扩繁促生的效果。经速度、加速度和受 n 力分析证明,该机满足了设计要求,是比较理想的牧草切根机械。 g i s 关键词 牧草 切根机 凸轮 直切刀 设计 e d 天 华 华天design 毕业设计说明书外文摘要 Design of Root-cutting Forage grass Machine——Frame Design Abstract n In order to counter the problem of reduced health promotion ability in g typical grass with compacted roots, a root-cutting machine was designed for i pasture. The machine used came driven of direct cutter to cut root vertically, s e d greatly reducing resistance and perturbations of soil surface while cutting the 天 root,which reached easy work in varies of forage. The machine destroyed 华 solid soil, imp roved grassland, and increased grass yield. As proven by analyzing the velocity, acceleration and force of the machine was able to meet the needs of designing. It is a more i
