TECHNICAL FIELD

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.


BACKGROUND

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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.



FIGS. 1-8 illustrate a first embodiment of a nozzle assembly and a nozzle carrier. FIG. 1 illustrates a perspective view of the nozzle assembly and nozzle carrier. The nozzle assembly 2 has a nozzle assembly body 4. The nozzle assembly is configured for connection to a fluid distributor 5 or sprinkler. The depicted fluid distributor 5 is configured to distribute fluid sprayed onto a distribution disc 7, although a variety of fluid distribution sprinklers can be utilized. The nozzle assembly has a fluid input 8 for receiving fluid, such as irrigation water, to be distributed. In the depicted embodiment the nozzle assembly has an adapter 64 for attaching to a fluid delivery line. Fluid enters the adapter and flows through a fluid delivery tube along flow path B to a nozzle formed with a nozzle bore 11 (shown in FIG. 4). The nozzle is formed or positioned in the elongate nozzle insert 6. The nozzle insert is formed as a substantially cylindrical body.


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 FIG. 1 the nozzle insert is depicted in the “RUN” position, meaning the nozzle is oriented within the nozzle bore such that fluid flows from the input, through the constricting nozzle, and onto the fluid distributor plate 7. When the nozzle insert is rotated to the “OFF” position, the nozzle insert blocks flow through the nozzle insert.


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 FIG. 3) that is biased into one of a series of detent notches on the circumference of the body of the nozzle insert to index the nozzle insert.


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.


In the depicted embodiment, a nozzle carrier is attached to the nozzle assembly body. The nozzle carrier 21 in the depicted embodiment has two cylindrical nozzle receivers 32, 34 housing two spare and/or replacement nozzles 28, 30. The replacement nozzles are held in by two retaining clips 31, 33 having tabs 35, 37.



FIG. 2 illustrates a back view of the nozzle assembly with the nozzle carrier detached. The nozzle carrier is configured to mount on a back panel 38 of the nozzle assembly body 4. A clip 40 is configured to retain the nozzle carrier on the plate 38. In the depicted embodiment, the nozzle carrier is configured to attach to the plate by utilizing a track and channel assembly. The edge of the plate 38 forms a track 39 onto which the opposing channels 60, 62 (shown in FIG. 3) are slid down onto. The nozzle carrier has a tab 63 onto which the clip 40 extending from the rear panel 38 of the nozzle assembly clips.



FIG. 3 illustrates a partially exploded view of the nozzle assembly of FIG. 1. The nozzle insert 6 is removed from the bore 10 of the nozzle assembly body. The front side 23 of the detent plate assembly has been removed illustrating detent plate 14 having detent 46. A spring 18 biases the detent plate such that the detent 46 is biased into the detent notches 42 of the nozzle insert. The detent notches (example being 42) are positioned extending into a circumferential ring 41. The second side 25 of the detent plate has a spring seat 48 which provides a base against which spring 18 extends to bias the detent plate to index the nozzle insert. The nozzle body utilizes a nozzle seat (not shown) into which seal 50 is positioned. The seal allows for the rotation of the nozzle insert and prevents fluid from bypassing the nozzle insert. Seal retainer 52 retains the nozzle seal 50 in the correct position. Connectors 54 attach the faceplate of the detent plate housing 13 to the detent plate housing. The bore in the nozzle assembly body is provided with two ribs (one rib is illustrated in FIG. 3 at 42) to align the nozzle insert in the bore. The outer circumference 72 of the outer face 74 of the nozzle insert serves to retain the biasing tab 46 within the circumferential groove in which the notches 42 are positioned. The circumferential groove has a second edge 76 into which the notches 42 is positioned. The detent 46 engages the detent notches 42 between outer circumference 72 and second edge 76 to retain the nozzle insert in the nozzle assembly body 4.



FIG. 4 illustrates a section view of the embodiment depicted in FIGS. 1-3. The nozzle insert is depicted in the run position providing a fluid flow path B. Fluid enters the nozzle assembly at adapter 64 passes through seal retainer 52 and into the nozzle bore 11 of the nozzle insert 6. The nozzle restricts fluid flow causing a stream of fluid to be sprayed onto the deflector plate 7. The sprinkler attachment 5 can be constructed as permanently attached to the nozzle assembly or removable from the nozzle assembly.

FIG. 15 illustrates a third embodiment of a nozzle assembly having a rotating nozzle insert. The nozzle assembly 150 has a nozzle body 152. The nozzle body has a bore 153 (shown in FIG. 17). The nozzle insert 157 is positioned within the bore. The nozzle body has a face 156 positioned at the opening of the bore. The opening is configured for insertion of the nozzle insert through the opening into the bore. The nozzle insert 157 has a circumferential plate 158. The face has a series of detent notches 168, 170, 172, 174 formed in the face. The detent notches are configured for meeting engagement of a series of detents 160, 162, 164, 166 formed in or positioned on the circumferential plate. The nozzle insert and nozzle body are each configured with a magnet 180, 182 respectably. When the detents of the nozzle insert are aligned with the detent notches, the magnet 182 of the nozzle body attracts the magnet 180 of the nozzle insert. This attractive force maintains the nozzle insert in position with the detents aligned in the detent notches. To rotate the nozzle insert, a user grasps the indicator knob 184 and rotates the indicator knob to the next operating position. The knob can be configured such that a pulling force is required to overcome the magnetic attraction between the magnets and/or the depressions and tables can be configured such that rotational force is sufficient to rotate the insert to the next operating position. For example, the depressions can be formed with ramp like sides on which the tabs slide when rotated into and out of the depressions. The user can then rotate the nozzle insert to the next position in which the tabs align with the depressions. The magnetic force will then maintain the nozzle insert in the selected operating position.


Alternatively the tabs and detent notches can be reversed, with the detent notches positioned on the nozzle insert, and one or more tabs positioned in the nozzle body.
