大豆玉米带状复合种植封闭式防飘移装置设计与试验
Design and Experiment of Enclosed Anti-Drift Device for Strip Compound Planting of Soybeans and Corn
摘要
Abstract
The strip compound planting mode of soybean and corn adopted the intercropping of soybean strips and corn strips with small plant spacing and dense planting,so as to achieve the effect of no reduction in maize yield and an addi-tional harvest of soybeans in one season,which could effectively solve the problem of competition for land between soy-beans and corn.In view of the serious cross-strip drift of droplets from existing plant protection machines under this planting mode,which couldn't meet the synchronous spraying requirements for soybeans and corn in plant protection,a closed anti-drift device for the strip-divided boom sprayer was designed.Firstly,through theoretical calculations of key components such as the lifting mechanism,wind-resistant telescopic frame,and electric push rod,drift simulation analy-ses of droplets were carried out under the conditions of 0 m/s and 3 m/s extreme air velocity based on Fluent software,thereby determining the structural parameters of its key components.Subsequently,static mechanics and modal analyses were performed on it using Ansys Workbench to ensure and verify the rationality and stability of the boom structure of the enclosed anti-drift device.Finally,a prototype was trial-manufactured and field performance tests were carried out.The results showed that under the conditions of driving speed of 3-6 km/h and a wind speed of 1.4-2.6 m/s,the maximum drift deposition amount of droplets of the closed anti-drift device is 10.49 droplets/cm2,which met the plant protection operation standards for the strip compound planting mode of soybean and corn,and could provide a reference for the re-search and development of efficient and low-loss plant protection and pesticide application equipment for the strip com-pound planting mode of soybean and corn.关键词
