1. Field of the Invention
This invention relates to improvements in a sprinkler. More particularly, the present 3D Rotor Sprinkler is a rotating sprinkler that further includes a spray nozzle that vertically oscillates to provide a more constant application of water to an irrigation area. This invention relates to the 3D Rotor sprinkler head that consists of the three dimensional, moving solid stream nozzle sprinkler system which is delivering the water droplet with the variable radial direction, and while this occurs, the sprinkler head is turning in a horizontal direction with a preselected arc and range or 360 degrees in a full circle.

This system is most ideal to have equal precipitation of the irrigation water in a designated area because of the water droplets being delivered in an equal amount per designated area in any given time. Furthermore, the characteristic of the solid stream nozzle can deliver water efficiently with low atmospheric air resistance, evaporation, and wind effect since the solid stream nozzle is delivering a single stream of water. Therefore, it can shoot a longer distance with less scatter under the same inlet water pressure. Several products and patents have been. Exemplary examples of patents covering these products are disclosed herein.
U.S. Pat. No. 5,372,307 issued Dec. 13, 2004 to George Sesser discloses a Rotary Sprinkler Stream Interrupter. This sprinkler uses a solid water stream that sprays onto a rotating head. The rotating head has a plurality of slots where each slot diverts the solid water stream into a different direction. This patent does not include a head that both pivots and rotates to evenly cover an irrigation area.
U.S. Pat. No. 4,925,098 issued May 15, 1990 to Jan Di Paola discloses an Underground-Installable Rotary Spray Irrigation Device, with Emission Angle Selectable from the Top. While the emission angle of this sprinkler is adjustable, the emission angle does not change as the sprinkler rotates. The angle is adjusted while the sprinkler is not in operation.
U.S. Pat. No. 7,427,038 issued Sep. 23, 2008 to Po-Hsiung Wang et al., discloses a Dual-Axis Rotating Sprinkler. The head of the sprinkler rotates over the top center of the sprinkler and further includes a plurality of different spray nozzles. While the head can rotate is two axes, the configuration of the head does not permit the spray head to be placed in an irrigation area because the top of the head is exposed and susceptible to damage as well as harm to people.
What is needed is an underground installable sprinkler where the solid stream spray nozzle can rotate up and down as well as rotate around to provide more even distribution of irrigation water.
It is an object of the 3D Rotor sprinkler has many advantages with wide spread use in the irrigation Industries. There is a need to irrigate large areas such as golf courses, parks, ball fields, playgrounds and agriculture crop growing areas.
3D Rotor sprinkler is well suited in residential or small landscape areas as well because of its controllable precipitation, radius, arc and distance by its tight control of three dimensional solid streams.
Therefore 3D Rotor sprinkler head will save substantial amount of irrigation water with equal precipitation, tight control of watering, eliminate over watering, minimize runoff, less evaporation losses in the atmosphere, less wind effect during the spraying, less watering time, and operate in low inlet water pressure.
It is accordingly an object of this invention to provide the “3D Rotor” three dimensional directions moving nozzle in which is rotating in a horizontal direction by the reversible driving gear which is integrated with the turbine and reduction gear. Then the driving cam moves the swivel turret in a vertical direction that is associated with the driving turbine and reduction gear mounted on the rotating sprinkler head. This 3 dimensional movement of the nozzle will deliver the water stream in an X.Y.Z. axis and makes the water with equal precipitation in an irrigation area during a spraying, and solid stream nozzle to reduce atmospheric resistance, wind effect, scattered water droplet, evaporation rate, over watering and to control the runoff. Therefore, this 3D Rotor will deliver the water droplet in longer distance with equal amounts of water in designated areas in given time and under the same inlet water pressure. This result will save the substantial amount of irrigation water with improved watering condition.
It is also an object of this invention to provide the 3D Rotor the solid stream nozzle consistently moves in a vertical direction by the driving cam to make a changing trajectory angle which varies the distance of water shooting distance in the range covers from 0 to maximum desired radius while the sprinkler head rotate horizontal direction in circle.
It is also an object of this invention to provide the 3D Rotor sprinkler head is rotated in a horizontal direction and reciprocating in preset arc or full circle in 360 degree by the integrated driving gear train and the turbine. The preset arc adjustment screw head is located on top of the sprinkler head.
It is also an object of this invention to provide the solid stream nozzle shooting the water in a solid stream to reduce evaporation in the atmosphere by minimizing the scattered water droplets and to prevent a wind effect unlike an ordinary spraying-type sprinkler. This solid stream nozzle can be adapted to the unique 3D Rotor which delivers the water in an X.Y.Z. axis and precipitation to an entire irrigation area. The solid stream nozzle is interchangeable in different sizes for a different flow rate.
It is also an object of this invention to provide the 3D Rotor sprinkler head can be operated by relatively lower water pressure because of the character of solid stream jet nozzle can shoot longer distance under same water pressure.
Various objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.
The 3D Rotor sprinkler consists of the drive mechanism and the components of the preset arc adjustment device. The outer protective casing or stationary lower body 26 consists of a water inlet connector, retractable coil spring 38, seal and seal cover 37. The riser stem consists of a tubular body 27, a screen filter 34, a pressure regulator 32, a turbine wheel 30, a speed control vale 31, a gear reducer 29, a horizontal rotate gear 28, reciprocating trip mechanism, and an arc setting device 50. One key element of the 3D rotor is a vertically swivel turret which is driven by the rotating cam 16 integrated with the turbine 53 and speed reduction gear 52. The swivel turret consists of the turning pivot bearing, the arm lever with the cam follower, the water inlet connector with the rotary joint and the flow control valve. The groove of the cam is designed to move the swivel turret in an equal area covered by a variable trajectory angle change.
The horizontal rotatable sprinkler upper head assembly includes a upper head assembly 11, a vertically swivel turret 43, a support pivot bearing assembly 44, a arm lever 48, a cam follower 47, an activating drum cam 46, an angle adjustment device 49, a cam driving gear reducer 52, a turbine 53, a speed control 54, a solid jet stream nozzle 55, an inlet water conduit 42 with rotary joint 42A, a water flow control valve 51 where the valve is controlled with a screw located on top of head and a protective cover 59.
The vertical swivel turret 43 is moving vertically within a support pivot bearing assembly 44, that is connected to the rotary joint 42A and an inlet water conduit 42, whereby changing the trajectory angle of the jet nozzle that is driven by the activating drum cam 46, and then the solid jet stream nozzle 55 shoots the single stream of water delivering to cover radial direction. The solid jet stream nozzle is controlled with worm gear 20.
The cannon vertical oscillating mechanism as shown in
The 3 D Cannon rotor further includes a rotary ball joint 12, a ball joint casing 14, a water conduit 13 and an interchangeable solid stream nozzle tip 15 where the tip is selected based upon the desired flow rate. The interchangeable solid jet stream nozzle 55 has different sizes for different flow rate of water that is determined according to the kind of irrigation park area, condition of soil, and type of grass.
Thus, specific embodiments of a 3D cannon rotor sprinkler have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
