A new type lightweight and small irrigation machine with dual purpose of sprinkling irrigation and hose irrigation dual purpose was introduced, whose height and sprinkling breadth was adjustable. The water distribution uniformity of machine was studied by theoretical analysis and experimental validation, primary factors of which were analyzed, and sprinkling intensity and uniformity coefficient were calculated when the machine collocated sprinkling irrigation and hose irrigation system. The result show that primary factors effecting water distribution uniformity of machine are water distribution uniformity and collocating space of sprinkler, stepped speed, soil and landform, as well as wind speed. In lab experiment, the sprinkling uniformity coefficient exceeded 95%, and hose irrigation uniformity coefficient reached 90%, which fully met irrigation demand.
