Definitions

  • the present invention relates to an adjustable circular sprinkler that has the functionality of watering all or part of a field with a square, rectangular or other shape.
  • the water is distributed through a piping system, in some cases driven by a water pump.
  • the piping, the engine, and the sprinkler must be designed so that the water flow is as uniform as possible.
  • Circular sprinklers comprised in the prior art are impact sprinklers, i.e. sprinklers designed to rotate in a full or partial circle.
  • Said circular sprinklers are characterized by the fact that the head of the circular sprinkler moves in a circular motion caused by the force of the water, thus rotating the sprinkler around a bearing that is fixed on a thread.
  • the sprinkler arm is repeatedly pushed into the water flow, by means of a spring, thus dispersing the water flow allowing uniform watering around the sprinkler.
  • Circular sprinklers are placed in order to water the entire crop, but as they water in a circular fashion, they invariably create spaces in the crop that are not watered, pressing farmers to place a new sprinkler in that area to water the missing part.
  • the sine wave serves to clarify how the innovative mechanism claimed here works.
  • the sinusoidal wave represents the inclination of the water nozzle of the sprinkler from which the water comes out, ie, unlike normal sprinklers, in the present invention the end through which the water is expelled is mobile and not fixed, allowing with the aid of a guide , that said sprinkler water nozzle moves horizontally, vertically, circularly and in line with a central body of the adjustable circular sprinkler described and claimed herein.
  • FIG. 1 Perspective view of the regular adjustable sprinkler
  • FIG. 2 Perspective view of the regular adjustable sprinkler where the window (13) can be seen;
  • FIG. 3 Perspective view of the guide (1)
  • FIG. 4 Perspective view of the nozzle (2)
  • FIG. 5 Perspective view of the nozzle (2) and the guide (1)
  • FIG. 6 Perspective view of the central body (2)
  • FIG. 7 Perspective view of the fixation device (5)
  • FIG. 8 Perspective view of the fixation device (5) and the guide (1);
  • FIG. 10 View of an area watered by a circular sprinkler and an adjustable circular sprinkler
  • FIG. 11 View of an area watered by a circular sprinkler
  • FIG. 12 View of an area watered by an adjustable circular sprinkler and representation of the sinusoidal mathematical function.
  • the guide (1) shown in figures 1, 2, 3, 5 and 8, horizontally, vertically and circularly controls a water nozzle (2), which rotates in line with a central sprinkler body (3).
  • Figures 1, 2, 3, 5 and 8 show the guide (1) which comprises a shape that is predefined according to the position where it is placed and also with the shape of the field to be watered.
  • the guide (1) has a sinusoidal shape or, according to another embodiment of the present invention, a shape that is defined according to the position and shape of the field to be watered, as is the case, among others, of a toothed shape.
  • the guide (1) is continuous and is located around the central body (3) and fixed to the fixing device (5).
  • the profile of the guide (1) also comprises different shapes, such as:
  • Figures 1, 2, 3, 5 and 8 show the guide (1) which comprises a shape that is predefined according to the position where it is placed and also with the shape of the field to be watered.
  • the guide (1) has a sinusoidal shape or, according to another embodiment of the present invention, a shape that is defined according to the position and shape of the field to be watered, as is the case, among others, of a toothed shape.
  • the guide (1) can be located around all or part (not shown in the figures) of the central body (3) and also attached to the fixing device (5).
  • the guide (1) comprises projections (20) located along the path of the guide (1) to section and temporally limit the movement of the water nozzle (20).
  • ridges (20) The location of these ridges (20) is stipulated according to the need for irrigation intensity, ie, if there is a certain area that for some reason requires a larger amount of water, 1, 2, 3 or more ridges will be placed (20 ) consecutively, so that the water nozzle (2) remains longer to release water in that respective area of the field.
  • the flexible intermediate tube (22) will allow the water nozzle (2) to move horizontally, vertically and circularly, in line and concentrically with the central body (3).
  • the central body (3) comprises on the surface of the upper part (6) a window (13) for fitting, passing and moving the tube (8), which rotates in line and concentrically with the central body, through the mechanism (7 ).
  • the tube (8) mentioned above is made of a rigid material.
  • the intermediate tube (22), attached to the end of the tube (8) is made of a flexible material, so that it can move in line and concentrically with the central body (3).
  • Figures 1, 2, 7 and 8 show the fixation device (5) which is located below the central body (3) and is fitted to the central body (3), in order to rotate freely around the central body (3).
  • the thread of the fixture (4) has the functionality of screwing the adjustable circular sprinkler, described and claimed here, to a hose for water supply.
  • Figures 1, 2 and 7 show the mechanism (7) for dispersing water and for rotating the central body (3) and the water nozzle (2) which is fitted to the vertical and central spike (19).
