This application claims the benefit of U.S. Nonprovisional application Ser. No. 17/024,190, filed Sep. 17, 2020 the disclosure of which is incorporated by reference.
The presently disclosed technology relates to a nozzle and nozzle body for use with an irrigation sprinkler. More particularly, the present invention is a nozzle body having a removable nozzle insert configured to rotate to a plurality of operating positions within the nozzle body.
Agricultural irrigation systems typically utilize a main distribution line, such as a center pivot, that leads to a series of individual distribution lines that utilize one or more sprinklers. A variety of sprinklers exist that serve to distribute the irrigation water in a variety of ways, with a common mechanism being to spray fluid from a nozzle or nozzle-like structure onto a distribution plate or disc. Irrigation water delivered by these systems is often delivered by canal or taken directly from a natural source. The irrigation water can have dirt or other debris in the material that can lead to clogging of the sprinkler nozzles and/or valves leading to the sprinklers. Accordingly what is needed is an improved nozzle and/or sprinkler that allows for flushing of the nozzle, facilitates simple replacement of the nozzle with varying nozzle sizes, and provides for flushing of the line above the nozzle without requiring detachment of the sprinkler from the irrigation line.
The purpose of the Summary is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Summary is neither intended to define the inventive concept(s) of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the inventive concept(s) in any way.

Accordingly, the drawings and description of the preferred embodiments are to be regarded as illustrative in nature, and not as restrictive in nature
While the presently disclosed inventive concept(s) is susceptible of various modifications and alternative constructions, certain illustrated embodiments thereof have been shown in the drawings and will be described below in detail. It should be understood, however, that there is no intention to limit the inventive concept(s) to the specific form disclosed, but, on the contrary, the presently disclosed and claimed inventive concept(s) is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the inventive concept(s) as defined in the claims.
The nozzle insert has a nozzle bore (illustrated in subsequent figures) extending through the nozzle insert in a generally perpendicular orientation to the axis of rotation of the insert body. The nozzle bore has an inlet end (inlet orifice) and an outlet end (outlet orifice) configured for fluid flow therethrough. As shown in subsequent drawings, the inlet end is larger than the outlet end, with the nozzle bore narrowing as it extends from the inlet end to the outlet end to constrict fluid flow through the nozzle bore such that the nozzle bore functions as a nozzle when the nozzle insert is positioned in the nozzle body in the RUN position.
The nozzle insert 6 is positioned through a detent plate assembly 12 into a nozzle bore 10 formed in the nozzle assembly body 4. The detent plate housing 13 has a series of operating indicators, “RUN” 20, “OFF” 22, “FLUSH” 24, and “LINE FLUSH” 26 on the outer surface of the detent plate housing. The nozzle insert is configured with an indicator knob 9. The indicator knob is configured to point at the operating indicator to indicate the position of the nozzle of the nozzle insert in the nozzle bore. In
The nozzle insert is configured such that fluid enters the nozzle assembly along fluid path B and passes through the nozzle assembly body, through the nozzle, and to the sprinkler distribution disc 7 when the sprinkler is operated with the nozzle insert in the run position depicted. In the flush position, the nozzle insert is reversed such that fluid flows in a reverse direction through the nozzle bore within the nozzle insert to clear debris from the nozzle. In the line flush position, the nozzle insert is oriented such that a channel on the side of the nozzle insert is positioned such that fluid flowing into the nozzle assembly is directed in the channel of the nozzle insert and out a flush port on the side of the body. The LINE FLUSH position allows for the flushing the irrigation line and nozzle assembly upstream from the nozzle without flushing any debris through the nozzle.
A detent plate assembly 12 utilizes a detent plate 14 housed within a detent plate housing 13. The detent plate housing has an opening 15 through which a tab 17 of the detent plate extends. The detent plate tab 17 is configured for a user to depress the tab 17 toward the nozzle insert to release the detent on the rotation of the nozzle insert. A biasing mechanism, depicted as a spring 18, biases the detent plate to arrest rotation of the nozzle insert. The detent plate has a detent 46 (shown in
The detent plate has an opening 16 through which the nozzle insert is positioned. The angled sides of the detent and detent faces allow the detent to release from the detent grooves as the nozzle is manually rotated. The detent slides along the circumferential ring 41 until it engages the next detent notch. To remove the nozzle insert, the detent tab must be depressed toward the nozzle insert. Release of the detent from the nozzle insert outer edges 72, 76 allows the removal and insertion of the nozzle. The nozzle insert is preferably configured with four detent notches configured to coincide with an operating position shown on the face plate of the detent plate. In a preferred embodiment the detent plate assembly is formed with two opposing sides 23, 25 with a cavity formed between that houses the detent plate.
