摘要
【目的】解决常规开沟刀开沟宽度和开沟深度不足,不能满足新疆地区葡萄开沟埋藤的种植模式的需求问题.【方法】本研究在原有刀具的基础上改进设计了风扇式旋叶开沟刀辊,利用逆向工程得到旋叶刀的三维模型,基于SPH算法对其进行切削土壤的显示动力学分析,得到最优的开沟工作速度及刀辊转速,并对旋叶刀辊的弯折角进行了分析,将其安装在相应动力的小型开沟机上进行了田间试验.【结果】一副刀辊单次开沟深度在200mm,宽度可达400mm以上,且刨土效果良好,沟底成圆弧形,开沟后土散落在沟两侧,经过两次开沟即可达到所需的要求.【结论】该旋叶刀辊的开沟深度和宽度满足了新疆石河子地区葡萄园的农艺要求.
【Objective】To develop the trenching blade with more width and depth.【Method】On the basis of original tool designing,a fan-style rotary knife roller was designed by reverse engineering.A 3 D model of rotating impeller blade was obtained based on SPH algorithm for the display of cutting soil dynamics analysis.The optimal trenching speed and rotation speed were gotten,the bending angle of rotary blade was analyzed.The trenching blade was installed in the corresponding dynamic small furrowing machine,and the field experiment was carried on.【Result】A single knife roller,trenching depth in 200 mm and width reached more than 400 mm,and the effect of digging soil showed good,the groove became circular arc form.After furrowing the soil scattered on both sides of the ditch.Two times trenching met the requirement.【Conclusion】The trenching depth and width of rotary blade is satisfied the vineyard agricultural requirements in Shihezi.
