无人机撒施装置结构设计与试验
Structural Design and Experiment of UAV Spreading Device
摘要
Abstract
Aiming at the problems of poor passing ability and low topdressing efficiency of crops in the middle and late growth stage.In this paper,to explore a new high-efficiency fertilization operation mode with accurate opposite-row and controllable variables,multi-rotor unmanned aerial vehicle(UAV)was used as the carrier,and based on the aerodynam-ic principle,combined with the agronomic requirements of rice planting and fertilization,a pneumatic opposite-row preci-sion fertilization device suitable for UAV was designed.The fertilization device can realize the precise regulation of row variable fertilization during topdressing operation of unmanned aerial vehicle.In order to test the operation performance of UAV fertilizing device,the stability of single fertilization apparatus,the consistency of six rows of fertilizing units and the deviation of fertilizing amount were studied.The experiment of fertilizing device at the rotating speed level of 10-60 r/min showed that the maximum variation coefficient of consistency between rows of fertilizing device was 3.85%,the maximum variation coefficient of stability of fertilizing amount was 3.34%.The experiment of fertilization amount deviation showed that the fertilization amount deviation was controlled below 4.32%under the given fertilization amount of 250 kg/hm2,which indicated that the overall stability of the fertilization device was high.It can provide reference for further research of UAV spreading device.关键词
