ABSTRACT:
Discloses a center pivot-type sprinkler irrigation system including an elongate rotatable irrigation pipe adapted to be horizontally pivoted at one end with a pipe swivel means connecting a conduit with the irrigation pipe and permitting both vertical pivoting and horizontal swiveling of the irrigation pipe around the conduit. A motor driving means connected between the conduit and the irrigation pipe horizontally rotates the pipe with respect to the conduit. A plurality of support wheels are mounted in spaced apart relation along the pipe to rotate freely around the pipe. A driving mechanism is connected between each support wheel and with the irrigation pipe for driving and rotating each wheel a designated distance along a circular path on the ground with each complete rotation of the irrigation pipe. The designated distance for each respective wheel is selected such that the entire length of the irrigation pipe is pivoted in a substantially straight line around the supply conduit by movement of the wheels. A plurality of novel sprinklers are mounted along and around the irrigation pipe to spray a substantially even ground distribution of water along the length of the pipe as the pipe pivoted around the supply conduit.
