喷灌机是由动力、水泵、管道、喷头、机架及其可靠的移动机构等部分组成。在这些组成部件中,动力、水泵已有较成熟的设计理论和系列可供选用,喷头、管道也有很多研究,有不少性能好的产品系列出现,而这些部件的组合和移动方式就是喷灌机要解决的问题。在国外,最早采用喷灌的国家,大多是从固定式喷灌系统开始的,其动力,水泵、管道、喷头等固定不动,虽然,固定式喷灌系统有许多优点,但是,它的最大弊病是设备多、投资大,这使发展推广喷灌受到了很大的限制。后来,人们才采用了移动式和半固定 Irrigation machine is powered, pumps, pipes, nozzles, racks and their reliable mobile institutions and other components. Among these components, power, water pumps have more mature design theory and series to choose from, the nozzle, the pipeline has also been a lot of research, there are many good performance of the product line, and the combination of these components and moving means is the irrigation machine Problem to be solved. Abroad, the earliest sprinkler irrigation countries, mostly from the fixed sprinkler system, the power, pumps, pipes, nozzles and other fixed, although the fixed sprinkler system has many advantages, but its biggest drawback is the equipment More investment, which makes development and promotion of sprinkling has been greatly limited. Later, people only used mobile and semi-fixed
