摘要
葡萄园篱架式的种植方式和其果树冠层的特殊性,使得传统的轴流风机风送式喷雾机已经不适合葡萄园植保作业。针对这一现状,研制了一种以小四轮拖拉机为动力源,适用于葡萄园作业的立体喷杆风送式喷雾机。通过Pro/MECHANICA有限元分析软件和流体仿真软件FLUENT分别对机架结构和气流流畅进行了分析模拟。结果表明:整机结构可靠,出风口面积为3.5 cm2,间距为80 mm时,风速均匀性良好,且槽型出风口较圆形出风口更合理。
Because of the Vineyard hedge frame planting and the particularity of grapevines canopy, the tradi- tional axial flow air - assisted sprayer has not suitable for the vineyard eppo homework. In view of this situation, a kind of air - assisted sprayer for vineyard on a small four wheel tractor which provides power for the sprayer has been developed. The chassis of structure and air flow field has been analyzed and simulated by Pro/MECHANI- CA and FLUENT analysis software. The results show that the whole structure is reliable and when the outlet - whose area is 3.5 cm2 and spacing is 80 mm, the groove wind speed is more uniform.
