喷灌机联动双喷头设计

Double-nozzle Curly Tubular Watering Machine Design

节水灌溉是农业现代化的重要组成部分,发展节水灌溉、提高水利用率是实现现代化的必由之路。目前我国的情况是:一方面水资源严重不足,另一方面农业灌溉水的利用率很低,浪费十分严重。我国农业灌溉长期沿用原始的灌溉方法,因此节水空间很大。通过对单喷头卷管式喷灌机的喷头车受力分析,找到其问题产生的原因,再通过理论力学分析,设计几种联动双喷头装置,使得喷头喷射水的反作用力的合力方向始终与输水管方向一致,利用输水管平衡其反作用力,保持工作稳定性。

Water-saving irrigation is one of the most important parts of the agriculture modernization.The development of saving water and the raising of the water use factor are necessity to modernization.Currently,the state is that on one hand the water resources are serious insufficient,on the other hand the water use factor is very low,the waste is extremely serious.As using the original irrigative method,there is a big space to save water.After analyzing the stress of the single nozzle machine,and through the theoretical mechanics analysis,several kind of interactive double-nozzle installments of which the direction of the reacting force is the same with that of the conduit have been designed.Working stability is higher.
