  • VARIABLE RATE IRRIGATION USING MOTION SENSOR
    Publication number: 20240081202
    Abstract: A sprinkler controller is cooperable with a sprinkler assembly that receives fluid input from a pipe span. The sprinkler controller includes a microcontroller circuit, a motion sensor coupled with the microcontroller circuit, and a valve assembly including a modulator coupled with the microcontroller circuit and a valve coupled with the sprinkler assembly. The valve meters or controls an amount of fluid output from the sprinkler assembly, and the microcontroller circuit is programmed to control the valve assembly based on input from the motion sensor. With a series of sprinkler controllers in a center pivot irrigation system, the drop numbers for each of the sprinkler assemblies can be determined based on input from the motion sensors.

  • Multi-nozzle shuttle for a sprinkler head
    Patent number: 9095859
    Abstract: A sprinkler head includes a sprinkler body having an inlet bore at one end, and a coupling element at an opposite end adapted to connect the sprinkler body to a water deflector plate. A multi-nozzle shuttle supports at least two nozzles and is attached to the sprinkler body axially between the inlet bore and the coupling element for swinging pivotal movement between two nozzle-installed positions. The multi-nozzle shuttle may also be provided with a shut-off surface portion for shutting off flow through the sprinkler body when the multi-nozzle shuttle is moved to a shut-off position. The shuttle may be moved manually or by a power actuator.
