茶园仿生掘耕刀具设计与试验
Design and experiment of bionic digging tool for tea garden
摘要
Abstract
To address the issue of high resistance and energy consumption during the process of digging in the tea garden,this paper conducted a bionic design for the digging tool structure based on the toe contour curve of the pangolin claw.Orthogonal experiments were used to design a bionic convex structure on the tool surface and the discrete element method was employed to assess the impact level of different parameter combinations on digging resistance,the optimal combination of parameters was determined to be the convex structure width of 5.0 mm and the convex structure height of 3.0 mm,the optimal parameters were used to conduct fully bionic tool design and tillage simulation analysis.Analysis showed that the use of fully bionic digging tools could theoretically reduce resistance by 35.4%.Finally,subsequent field experiments demonstrated that utilizing this bionic digging tool for tea garden cultivation management led to a 30.6%reduction in resistance,indicating its superior effectiveness in reducing resistance.Furthermore,comparative analyses of tillage quality indicators such as tillage depth and tillage depth variation coefficient were carried out,it was found that this bionic digging tool not only reduced resistance but also exhibited high-quality performance in tea garden management.关键词
