机动取土器取土杆结构的设计
|
摘要
土壤成分影响着农作物的质量与产量,因而对于土壤破坏的研究与修复,是一项重要的工作。土壤的取样,有时需在土壤表面取土,有时需要在地面下某深处取样,需要一种专用取土器进行取样。为此,着重研究了机动取土器取土部分,设计了一种新的取土杆结构,使得在只需更换取土结构的情况下,满足不同规格的取土要求,以便于方便、快捷取土。同时,应用Ansys软件对其进行有限元分析,确保所设计结构的可行性。设计的取土器能满足不同规格土壤取土要求,为取土器结构设计提供了一种新思路。
Soil composition influences the quality and yield of crops; research and restoration of soil destruction is also an important task. Soil sampling,on the other hand,requires soil extraction on the soil surface,and sometimes requires sampling at a certain depth below the ground. This requires a special earth picker is used for sampling. This paper focuses on the part of the earth borrowed from the motorized earth picker and designs a new earth picking rod structure so that the earth borrowing requirements of different specifications can be satisfied only when the earth borrowing structure is replaced. It is convenient and fast to take soil,and apply finite element analysis to the ansys software to ensure the feasibility of the designed structure. The design of the earth picker can meet the requirements of different specifications for soil extraction,and provides a new idea for the structure design of the earth borrower.
