Abstract：A new type of light weight and small size machine with sprinkling irrigation and hose irrigation was introduced.The machine′s set of remotion and pressure water are provided by a capstan car,and sprinkling irrigation by a sprinkler car.The machine has sprinkling irrigation and hose irrigation system,and can satisfy different farm crops in different growth time at the request of water.The sprinkler car set can adjust the height of machine,which makes the sprinkler to always work in the best sprinkling height.The machine adopts lower press refraction type sprinkler and hose tube for lower press irrigation system,which makes the machine′s work press to drop 30%.By studying the machines water turbine characteristic,amovement characteristic,and insufflations characteristic,the machine′s technical parameters were determined.Test results show that the new machine may reduce the influence of sprinkling uniformity degree by wind,reduce the water loss,and irrigation uniformity degree can be increased by 90%.
