J. Taghavi1 2Department of Mechanical Engineering, Iran University of Science and Technology, Iran ABSTRACT This paper reviews different agricultural sprinklers with squared plane irrigation ability and determines the limitations and their use as a structure for irrigation. The mechanical agricultural sprinkler with squared plane irrigation ability presents the most effective design. A number of theoretical methods are put forward to explain sprinkler characteristics and these are verified by an analysis of experimental data. A study of change in the angle of sprinkler rotation, which changes the angle of nozzle outlet and its distance of throw, leads to recommendations for the new system. By designing the follower on the cam, the angle of the nozzle is changed. The moment created by flow discharge and the atmosphere is the force for turning the sprinkler. The CATIA software is used to design and simulate the structure. Reference: Taghavi, J., R.G. Ahangar, M.Z. Ahmadi, Gh. Aghajani, and M. Hasirchian. 2009.
