毕业设计说明书中文摘要 TDJ-1小型条带喷灌机喷头支架改进设计 摘 要：本设计针对现有圆形喷灌设备中存在的推广难、成本高和喷洒均匀度低等缺点，采取了一系列的改进设计。设计出了适合条带喷灌设备的支架。本设计的条带喷灌机喷头支架成本低、使用方便、适合固定喷灌与移动式喷灌。 喷灌技术的应用是实现农业高效用水的主要举措。喷灌是一种先进的喷水方法，近年来，喷灌技术在国内外发展很快，是农田灌溉的发展方向，已成为农业现代化的重要组成部分。它具有许多优点，已被越来越广泛地应用于农业生产。作为人口众多的贫水国家，正处在经济建设发展阶段，节约用水并实现高效用水，尤其在用水量比较大的农业生产方面来讲，是保证农业持续发展的一项重要措施，具有重要的战略性意义。 关键词：喷灌 支架 喷头 条带喷灌机 毕业设计说明书外文摘要 TDJ-1 Banding watering machine nozzle design Abstract This design the promotion which exists in view of the existing circular spray irrigation equipment in difficult, the cost high and sprays the uniformity low status shortcoming, has adopted a series of improvement design. Designed has suited the banding spray irrigation equipment the support. This design banding watering machine nozzle support cost low, the easy to operate, suits the fixed spray irrigation and the motion type spray irrigation. The spray irrigation technology application realizes the agricultural university water used main action. The spray irrigation is one advanced spraying of water method, the spray irrigation technology was in recent years very quick in the domestic and foreign development, was the farmland irrigation development direction, has become the agriculture modernization the important constituent. It has many merits, more and more widely has been applied in the agricultural production. As the large population poor water country, is occupying the economic development development phase, saves the water used and realizes the highly effective water used, says especially in the water consumption quite big agricultural production aspect, is guaranteed the agriculture develops continually an important measure, has the vital strategic significance.
