Abstract
A high vibration sprinkler is hung from a movable, elongated pipe by a flexible hose. The connection of the hose to the sprinkler is by rigid, poly-vinyl chloride plastic hose barbs, tubes and fittings. The PVC connections dampen and tolerate the vibration of the sprinkler.
Claims8
A process for dispersing water from an irrigation system having:
- a) an elevated horizontal elongated pipe adapted to carry water under pressure,
- b) a plurality of vehicles forming means attached to said horizontal pipe for supporting said pipe above growing crops and for moving said horizontal pipe transversely of its length, and
- c) a plurality of sprinklers, each sprinkler having
- i) a sprinkler axis,
- ii) a rotatable dispersion element which vibrates excessively causing shock, said dispersion element mounted for rotation about the sprinkler axis;
- the improved method for connecting each of the sprinklers to a horizontal pipe comprising:
- d) forming a G-Shaped rigid holder from shock tolerant thermoplastic material,
- e) attaching the sprinkler to a G-shaped rigid holder,
- f) attaching the holder to a flexible hose by a hose barb having a barb axis,
- g) connecting the flexible hose to the horizontal pipe,
- h) positioning the dispersion element below the barb.
