摘要
为了提高无人机撒播种子分布均匀度和撒播质量,研究了搭载撒播系统的无人机作业参数对种子分布的影响。通过设计正交试验研究了无人机撒播系统出料口大小、飞行高度和转盘转速对黄芪种子在田间的分布影响。试验以电动四旋翼无人机为载体、圆形接收盘为种子采集器。结果表明:极差分析法中,RB(14.9%)﹥RA(13.4%)﹥RC(5.4%),说明影响种子分布均匀性的主次因素依次为飞行高度、出料口大小、转盘转速;出料口大小、飞行高度和转盘转速的最小Ki值分别为36.5%、37.5%和40.6%。因此,最优作业参数为:撒播系统出料口大小为13/30,飞行高度为1.5m,转盘转速为10/30。该研究可为无人机撒播作业提供参考。
In order to improve the uniformity of seed distribution and the sowing quality of unmanned aerial vehicle(UAV),the influence of operating parameters of UAV equipped with sowing device on seed distribution was studied.In this paper,the effects of opening of outlet,flying height and turntable rotating speed on the distribution of astragalus seeds in the field were studied by designing orthogonal experiment.In the experiment,the electric four-rotor UAV was used as the carrier and the circular receiving disk was used as the seed collector.The results show that RB(14.9%)>RA(13.4%)>RC(5.4%)in the range analysis method indicated that the primary and secondary factors affecting the uniformity of seed distribution were:flight height,outlet opening,turntable rotating speed.The minimum values Ki of outlet opening size,flight height and rotary speed were 36.5%,37.5%and 40.6%,respectively.Therefore,the optimal operating parameters were:outlet opening of broadcasting system was 13/30,flight height was 1.5 m,and rotary speed was 10/30.This study provides a reference for sowing operation of UAV.
