Abstract

An irrigation unit (10) includes a housing (200), a nozzle (220), a first mover (238) and a second mover (268). The nozzle (220) is secured to the housing (200) and is in fluid communication with a fluid source (18). The first mover (238) rotates the nozzle (220) about a first axis, and the second mover (268) rotates the nozzle (220) about a second axis that is different than the first axis. In one embodiment, the second axis is substantially perpendicular to the first axis. At least a portion of the housing (200) can movably extend along the first axis. The second mover (268) can rotate the nozzle (220) about the second axis based upon a pressure of a fluid (19) within the housing (200) and/or upon position of an area (30) relative to the nozzle (220). Further, the second mover (268) can oscillate the nozzle (220) about the second axis. The rotation of the nozzle (220) about the second axis can also be based upon at least one of a wind direction and a wind speed near the nozzle (220).

Claims

1. An irrigation unit for irrigating an area with a fluid from a fluid source, the irrigation unit comprising:

a housing having a portion that movably extends along a first axis;

a nozzle that is at least partially positioned within the housing, the nozzle being in fluid communication with the fluid source so that fluid from the fluid source is transferred to the nozzle; and

a first mover that pivots the nozzle relative to the housing about a second axis that is different than the first axis.

2. The irrigation unit of claim 1 further comprising a second mover that rotates the nozzle about the first axis.

3. The irrigation unit of claim 1 wherein the second axis is substantially perpendicular to the first axis.

4. The irrigation unit of claim 1 wherein the first mover pivots the nozzle about the second axis based at least partially upon the position of the area relative to the nozzle.

5. The irrigation unit of claim 4 wherein the first mover pivots the nozzle about the second axis based at least partially upon a pressure of the fluid within the housing.

6. The irrigation unit of claim 1 wherein the first mover oscillates the nozzle about the second axis.

7. The irrigation unit of claim 1 wherein the pivoting of the nozzle about the second axis is at least partially based upon at least one of a wind direction and a wind speed near the nozzle.

8. The irrigation unit of claim 1 wherein the pivoting of the nozzle about the second axis is at least partially based upon a wind direction and a wind speed near the nozzle.

9. An irrigation unit for irrigating an area with a fluid from a fluid source, the irrigation unit comprising:

a housing;

a nozzle that is at least partially positioned within the housing, the nozzle being in fluid communication with the fluid source so that fluid from the fluid source is transferred to the nozzle;

a first mover that moves the nozzle along a first axis; and

a second mover that rotates the nozzle relative to the housing about the first axis and about a second axis that is different than the first axis.

10. The irrigation unit of claim 9 wherein the second axis is substantially perpendicular to the first axis.

11. The irrigation unit of claim 9 wherein at least a portion of the housing movably extends along the first axis.

12. The irrigation unit of claim 11 wherein the second mover rotates the nozzle about the second axis based at least partially upon a pressure of the fluid within the housing.

13. The irrigation unit of claim 11 wherein the second mover rotates the nozzle about the second axis based at least partially upon position of the area relative to the nozzle.

14. The irrigation unit of claim 13 wherein the second mover rotates the nozzle about the second axis based at least partially upon a pressure of the fluid within the housing.

15. The irrigation unit of claim 9 wherein the second mover oscillates the nozzle about the second axis.

16. The irrigation unit of claim 9 wherein the rotation of the nozzle about the second axis is at least partially based upon at least one of a wind direction and a wind speed near the nozzle.

17. The irrigation unit of claim 9 wherein the rotation of the nozzle about the second axis is at least partially based upon a wind direction and a wind speed near the nozzle.

18. A method for irrigating an area with a fluid from a fluid source, the method comprising the steps of:

delivering the fluid to a nozzle that is at least partially positioned within a housing;

moving a portion of the housing along a first axis with a first mover; and

rotating the nozzle relative to the housing about the first axis and about a second axis with a second mover, the second axis being different than the first axis.

19. The method of claim 18 wherein the step of rotating the nozzle with the second mover includes positioning the second axis to be substantially perpendicular to the first axis.

20. The method of claim 18 further comprising the step of moving the nozzle in a direction along the first axis.
