Abstract:A novel lateral move irrigation system was introduced based on the development trend of Sprinkler Irrigation system at home and abroad at present.The unit adopted the special connecting to realize the fast connection and disassembly of the device. The span number was flexibly changed for avoiding excessive spray and spray leakage phenomena of the unit with more special truss connections according to the terrain demand. The truss was equipped with special slotted manner which could change the nozzle installation height and spacing flexibility according to the crop water requirement. And it also could reduce floating and evaporation loss of sprinkler irrigation and improve the sprinkler irrigation uniformity. A low-pressure and spray-plate sprinkler nozzle equipped reduced the system pressure and saved energy consumption. The lateral move irrigation system adopted the intermittent control system to realize automation operation of the unit and fulfilled the requirements of modern far-ming precision irrigation. By analyzing the performance of the unit, the results show that when the pressure, sprinkler spacing and the height are 0.07 MPa,3 m and 1 m respectively, sprinkler irrigation uniformity coefficient reaches 86.5% and distribution uniformity coefficient reaches 80.9%. Compared with existing products, the unit has the advantages of easy disassembly, extensive adaptability, water saving, energy saving and high uniformity, so it has considerable prospects of applications.
