微型开沟机的设计学 生：易 彬指导老师：汤楚宙(农业大学工学院， 410128)摘 要：本文分析比较了国外开沟机械的工作方法和原理，结合我国现有的开沟方式与现有小型旋耕机大量使用的现状，比较了前置和后置式开沟方式设计圆盘式开沟部件，试设计一款微型开沟机。以 1dn-4 底盘为基础，后挂开沟机构。开沟机构动力与采纳牙嵌式离合器进行传递，从而工作机构和行走机构相互独立，不相干涉。开沟刀盘动力采纳链传动，结构简单、轻巧，运行灵活。采纳上抛，并设置挡土板，从而达到覆土要求，开沟刀盘后接开沟铲，达到了沟底平整的要求，设置弧形挡板，满足了操作安全性与碎土系数需要，安装升降可调尾轮装置，提高了操作舒适度和操作的方便性。在理论讨论的基础上，设计出开沟部件，并对开沟刀盘进行受力分析， 对刀辊轴进行校核。关键词：开沟；刀盘；抛土；Design of theMicro Ditching machineStudent:Yi binTutor:Tangchuzhou (Engineering college, HunanAgriculturalUniversity, Changsha 410128,China)Abstract ： The working methods and principles of the ditching machine coming form home and abroad are analyzed and compared in this paper. By combining the present ditchingmode in the advantages and disadvantages and the post-position that ditching mechine beingused. by comparing the front -set and back- set ditching part, Finally,try to design a mini ditching machine.On the base of the Lantian 1dn-4 micro rotary cultivator ,set a ditching part on the back,the working part and the moving part are independence corse of the power of the rotary cultivatortransfer from the stuckclutch.The cutter head drived by the chain wheel.the structure of integel setting are simply and smartly.To fit the need of the palling earth,we adopt the up casting method and set a poiling board on the above,set a ditching scroop on the back of the poiling board, unevenness of the channel bottom is also eliminated. Setting is baffle to satisfy the need of operation security and the coefficient o...
