Abstract

The present invention includes a variable sprinkler orifice device that can change orifice sizes using a rotating disk with multiple orifices along the circumference of the disk. According to first preferred embodiment, the implement preferably includes a conduit in which water is directed through a series of rotatable plates which preferably include incrementally sized orifices. According to a further preferred embodiment, the variable orifices are automatically and quickly adjusted based on VRI data to change the combination of orifices used.

Claims

1. A variable sprinkler orifice device, wherein the variable sprinkler orifice device comprises:

a plurality of disks, wherein each of the plurality of disks comprises a plurality of orifices along the circumference of the disk, further wherein the plurality of disks comprises a first disk and a second disk.

2. The variable sprinkler orifice device of claim 1, wherein the second disk is located upstream of the first disk.

3. The variable sprinkler orifice device of claim 2, wherein the plurality of disks include at least one fixed disk and at least one rotating disk.

4. The variable sprinkler device of claim 3, wherein the rotating disk is motorized.

5. The variable sprinkler device of claim 4, wherein motorized control is used to control the position of the motorized disk.

6. The variable sprinkler device of claim 1, wherein the water flow is monitored upstream of the plurality of disks.
