Abstract

Trail line irrigation moves have split swivel couplers of which each has two identical halves rotatable on split bearing rings on an axle having seals thereon and coupled to pipe lengths by press-on or clamp-on connector portion. The axle has holes connecting the pipe lengths to the interior of the swivel halves, and the bottom half has a check valve drain and the top half has a cross connector with a sprinkler mounted on the top, a quick connect coupler cross-arms, a plug in one cross-arm and a trail line coupled to one cross-arm. The trail line is connected by a quick connection coupler to a reversible skid shoe having a sprinkler riser and a drain plug.

Claims

1. For use in an irrigation line move including a rotatable horizontal line pipe having lateral ports and a swivel housing rotatable on the pipe around the ports, an irrigation trail line structure including

a cross connector having a vertical tubular portion having a bottom, pipe connecting portion connected to a port in the housing and also having an upper, sprinkler connecting portion,

the cross connector also having a tubular cross-arm, extending outwardly and downwardly from the vertical tubular portion and having a connector outer end portion adapted to connect to a trail line, the downward slope of the cross-arm being such as to so compensate for drag from the trail line that the tubular portion remains substantially vertical when the line pipe is moved laterally.

2. The irrigation trail line structure of claim 1 wherein the downward slope of the cross-arm is about 15°

.

3. The irrigation trail line structure of claim 1 including a second cross-arm like the first-mentioned cross-arm and similarly sloping downwardly, the cross-arms being on opposite sides of the tubular portion for alternate connection to the trail line.
