AI Technical Summary

Benefits of technology

Enables the simultaneous conveyance of multiple media streams and adjustable flow rates, enhancing the flexibility and efficiency of irrigation systems by allowing for precise control of fluid streams and incorporation of additives, improving crop management and water distribution.

Problems solved by technology

They do not provide for separate conveyances of fluid streams such as separate chemical or additive streams.
Although some irrigation systems may allow for selected discharge apparatus to be turned on or off, they only provide for one rate of flow while the discharge apparatus is operating.
There is no way to obtain an intermediate flow rate in instances where reduced flow rates are desired such as where the particular kind of crop has a low tolerance for overwatering.

Embodiment Construction

[0029]The distribution tube assembly 10 of the present invention is used in conjunction with an irrigation system. The irrigation system may consist of a fixed position system utilized for the production or protection of fruits, vegetables, vine crops etc. or it may be a temporary or movable system which can be relocated to serve multiple uses. The irrigation may be a typical center pivot irrigation machine such as the type found in U.S. Pat. Nos. 3,785,400, 3,983,898, 3,994,514, 4,127,181, 4,240,582, or 5,695,129, all assigned to Lindsay Manufacturing Company. The irrigation system may be of the type which is laterally movable such as that shown in U.S. Pat. No. 4,330,085, also assigned to Lindsay Manufacturing Company. It is further contemplated that the invention can be used in any other type of irrigation system which utilizes either rotational or linear movement or a combination thereof, or which consists of a fixed position system or it may be a temporary or movable system whi...

Abstract

A distribution tube assembly for an irrigation system having a main supply line for conveying fluid therein includes a first end, a second end and an internal surface defining at least two fluid passageways, at least one of the fluid passageways being in fluid communication with the main supply line. The other fluid passageway may be in fluid communication with an alternate supply line. Adaptors and regulators may be attached to the distribution tube assembly. The distribution tube assembly permits irrigation to be performed by multiple fluid streams, allows for the incorporation of chemicals within the distribution tube assembly, and provides for selectable flow control.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of prior application Ser. No. 09 / 872,604, filed Jun. 1, 2001.BACKGROUND OF THE INVENTION[0002]The present invention relates to irrigation systems of either the movable or fixed type. Conventional irrigation systems have a main supply line. In movable irrigation machines the supply line is commonly supported at intervals by wheels or mobile towers. Conventional movable or fixed irrigation systems have a main supply line which may be supported at some height above the earth, placed on the surface of the earth or buried within the earth. At various points along the supply line, a distribution tube extends from the main supply line to a pressure regulator and a nozzle or other suitable discharge devices. The distribution tube may extend upwardly, downwardly, laterally, or some combination of these. Conventional pressure regulators are well known in the art and supply a constant pressure to the associated disch...
