[目的]解决自走式水田高地隙喷杆喷雾机喷雾不均匀的问题。[方法]以10 m喷杆为试验对象,搭建喷杆喷雾试验平台,研究喷雾压力、喷雾高度、喷雾喷幅宽度对喷雾均匀性的影响。[结果]喷头压力为0.30 MPa,流量变异系数最小值为5.292 5%,喷雾流量稳定性最高;喷杆距作物水平高度0.5 m时,变异系数最小值为2.543 010 1%,喷雾均匀性最好;喷雾压力增加,喷幅宽度呈一定程度的正相关。喷雾压力0.30 MPa,喷雾高度0.5 m时,喷幅宽度为10.502 1 m,相对其他喷雾压力情况下,喷幅变异系数最小值为0.280 2%,喷雾喷幅最为稳定。[结论]该研究结果可为自走式水田高地隙喷杆喷雾机的进一步研究提供一定的参考。

[ Objective] In order to solve the problem of uneven spraying of rice boom sprayer. [ Method] In this paper,a spray rod with 10 m was used as material.The spray test plattbrm was set up to study the influence of splay pressure ,splay height and spray width on splay unifolxnity. [ Re- sult] The test results showed that the pressule of sprinkler head was 0.30 MPa,the minimum value of the flow coetficient was 5.292 5% ,and the stability of splay flow was the highest.When the splay rod is 0.5 m above the crop level, the minimum coefficient of variation is 2.543 010 1%, and the spray unifolxnity is...
