Abstract
A tube structure for attachment to an irrigation pipe for non-erosively distributing water from the pipe to the ground, the tube comprising a shapeable, deformable tubular first end portion, a plurality of retainer hooks secured to said first end portion and a second tubular end portion. A pair of spaced diffuser screens are positioned in, and extend transversely across, the second end portion of the tube.
Claims8
In combination:
- an irrigation pipe for conducting irrigation water;
- means for discharging water from the interior of the pipe to the ground through an opening in the wall of the pipe;
- and
- a tubular aeration device mounted adjacent the side of the pipe and positioned to communicate its interior with said opening in the wall of the pipe, said device comprising:
- a shapeable, manually deformable tubular first end portion of selectively variable cross-sectional configuration;
- a plurality of retainer hooks secured to said tubular first end portion, and including portions projecting normal to the axis of said tubular first end portion and radially outwardly of the external wall of said tubular first end portion;
- a second tubular end portion connected to said first tubular end portion;
- and
- a plurality of rigid diffusion screens positioned in, and extending transversely across, said second tubular end portion.

An aeration device adapted for attachment to an agriculture irrigation pipe comprising:
- an elongated tubular member having a manually deformable first tubular end portion shapeable to a selected cross-sectional configuration, and having a pair of axially spaced grooves in the internal wall of said tubular member at a location therein spaced from said first tubular end portion;
- a plurality of retainer hooks secured to said first tubular end portion and each including portions projecting radially outwardly with respect to said tubular member in a direction substantially normal to the axis thereof;
- and
- diffusion screen means extending transversely across said tubular member at a location therein spaced from said first tubular end portion and engaging said grooves in the internal wall of said tubular member.
