Definitions

  • the invention relates to an irrigator, in particular a mobile irrigator of a type destined to irrigate terrains of any form, such as agricultural land or football or rugby fields, or the like.
  • the prior art comprises mobile irrigators comprising a spray tube mounted on a trolley and connected via a flexible pipe to a water dispenser generally located externally of the terrain to be irrigated.
  • These irrigators are retreated, for example by means of traction exerted directly on the flexible pipe by action of a coil reel, while they direct a jet of water onto a portion of terrain arranged forward of the irrigator.
  • the irrigator follows a prevalent development direction of the terrain, while distributing a flow of water onto the zones surrounding the terrain.
  • the spray tube is generally rotated about a vertical axis by action of the flowing water, and the rotation of the spray tube is such as to cover an angle which is sufficient to irrigate the portion of terrain the irrigator is facing.
  • the rotation alternates back and forth and is commanded by commonly known devices for the inversion of the spray tube rotation.
  • the spray tube is turned towards the coil reel, such as initially to irrigate the marginal zones of the terrain which would otherwise not be irrigated by the circular trajectory of the jet.
  • the traction exerted on the flexible tube by the coil reel recalls the irrigator, tending to rotate it and bring it into the operating position, which is specular with regard to the above-described position.
  • the irrigator dispenses a water jet frontally, while retreating towards the coil reel under the traction force exerted thereby.
  • the central zone receives a quantity of water which is greater than that received by the lateral zones and the irrigator, together with its support trolley, moves into the muddy zone with the consequent risk that the irrigator, together with its support trolley, might stick or even stop altogether. This would lead to a risk of breakage of the flexible pipes, which would still be under traction on the part of the coil reel, while the irrigator would be unable to move.
  • pluviometers i.e. means for measuring the quantity of water dispensed onto the field to be irrigated in a predetermined time unit, it has been possible to measure, for traditional irrigators, the unit of water dispensed by the irrigator along the field to be irrigated.
  • Figure 1 shows a pluviometry graph of traditional known irrigators known on the market.
  • US 2986339 discloses a fluid motivated sprinkler adapted to discharge fluid over a predetermined distribution pattern, in which the retative saturation of different are as within the fluid distribution pattern is controllable.
  • the technical aim of the present invention is to provide an irrigator which does not provide a result exhibiting the above-described drawbacks.
  • an aim of the invention is to provide an irrigator which realises a uniform irrigation on terrains having a square or rectangular shape or, more in general, having an irregular shape.
  • a further aim of the invention is to provide a very reliable irrigator which is very safe to use.
  • 1 denotes in its entirety an irrigator of the present invention.
  • the irrigator 1 comprises a base 2 and a spray tube 3.
  • the spray tube 3 is internally crossed by a through-channel C and is rotatably coupled to the base 2 in order to rotate about a vertical rotation axis X.
  • the spray tube 3 has a lower portion 3a which extends along the rotation axis X and an upper portion 3b, connected to a lower portion 3a, which upper portion 3b extends in a distancing direction from the rotation axis X.
  • the upper portion exhibits a dispensing nozzle 4 of a jet of water and is connected to inversion means 5, 6 of the rotation of the spray tube 3.
  • the inversion means 5, 6, which are of substantially known type, comprise a command rod 5 and a check element 6, which are interconnected and act on a deviator element 7 acting at the position of the nozzle 4.
  • the check element 6 is destined to enter into contact with stop elements 8, arranged at the extreme positions reached by the check element 6 during operating rotation of the spray tube 3, and following contact with the stop elements 8 the check element 6 switches the deviator 7, inverting the rotation direction of the spray tube 3.
  • the spray tube 3 is set in rotation by the water jet dispensed from the nozzle 4 and colliding with the deviator element 7.
  • FIG. 3 is a detailed illustration of the structure of the irrigator 1.
  • the irrigator 1 comprises a flange 9, an intermediate element 10, a collar 11 and a covering element 12.
  • the four elements described are arranged about the rotation axis X and in a centred position with respect thereto, and have an operating function which will be described herein below.
  • the flange 9 is stably fixed to the base 2, for example by means of a plurality of screws, and the intermediate element 10 is stably keyed on the flange 9, for example by means of the fastening screws of the flange 9.
  • the flange 9 is preferably made of metal, for example aluminium, plastic or steel, while the intermediate element 10 is made of plastic or another material.
  • the intermediate element 10 exhibits a base portion 10a which serves to fasten the whole intermediate element 10 to the base 2, and a cylindrical wall 10b having a vertical development which stretches out from the base wall.
  • the cylindrical wall 10b has a circular section and is arranged coaxially to the rotation axis X.
  • the collar 11 comprises a curved plate 11a, preferably made of metal and arranged along an open circular profile and having two terminal portions 11b which can be connected to one another by fastening means 11c.
  • the curved plate 11a is substantially counter-shaped to the cylindrical lateral wall 10b of the intermediate element in order to be keyed on the cylindrical lateral wall 10b.
  • the collar 11 further comprises a hooking portion 11d defining a seating S, arranged preferably on a diametrically opposite side from the fastening means 11c, and even more preferably arranged externally of the circular profile along which the curved plate 11a develops.
  • the covering element 12 comprises a concave body 12a mounted with a concavity thereof facing downwards and in particular is destined to contain the flange 9, the intermediate element 10 and the collar 11.
  • the concave body 12a exhibits a tubular extension 12b extending internally of the concavity and internally insertable of the flange 9.
  • an annular housing A is thus created between the tubular extension 12b and a lateral portion 12c of the concave body 12a, in which housing A the intermediate element 10, keyed on the flange 9, and the collar 11 are arranged.
  • the concave body 12a exhibits a lateral protuberance 13 internally defining a broadening of the annular housing A and in which the fastening means 11c of the collar 11 are inserted.
  • the covering element 12, which is solidly constrained to the spray tube 3, is further solidly constrained to the collar 11 by means of a partially-threaded pin G which fits in an opening of the concave body 12a and at the same time engages the seating S of the collar 11.
  • a connecting element 14 is internally keyed to the extension 12, which connecting element 14 defines a downwards extension of the channel C.
  • the connecting element 14 passes through the intermediate element 10, the flange and the collar 11 and connects to an inlet opening N realised in the base 2.
  • the inlet opening N is in turn set in fluid communication with a source of water, not illustrated.
  • the connecting element 14 is supported to the base 2 by a bearing 15, an internal ring of which is externally keyed to the connecting element 14 and an external ring of which abuts on the base 2.
  • Seal rings T are also comprised, interposed between the rotatably connecting element 14 and the fixed base 2.
  • the irrigator 1 further comprises a guide element 16 stably fixed to the base 2, for example by means of screws, and exhibiting a guide surface 17 defining a cam.
  • the guide surface 17, which is preferably defined by a vertical wall 17a supported by a horizontal plate 17b extends about the rotation axis X by an angular amount which is equal to or greater than the angular range that the spray tube 3 covers during its rotation.
  • the irrigator 1 comprises a command bar 18, or screw, which passes through the two terminal portions 11b of the collar 11, and a nut screw 19 coupled by a thread to the screw 18.
  • the fastening means 11c comprise a first element 23 which is stably connected to a first terminal portion 11b of the collar 11, and a second element 24 which can be abutted to the first element 23 along an inclined surface 25 which at least partially extends in a nearing direction between the two elements 23, 24.
  • the two elements 23, 24 are reciprocally aligned and when they are neared to the minimum distance define an external cylindrical body.
  • the inclined surface 25 is such that a reciprocal rotation of the second element 24, rotating with respect to the fixed first element 23, causes a reciprocal nearing/distancing between the elements 23, 24, i.e. a screwing movement of the second element 24 with respect to the first element 23.
  • the fixed first element 23 and the rotating second element 24 are preferably respectively defined by a left-directed helix and a right-directed helix.
  • a nut screw 19 is abutted to the second terminal portion 11b of the collar 11, while the screw 18 passes through the two elements 23, 24 (preferably with play, i.e. not coupled to the two elements 23, 24) and terminates in the illustrated preferred embodiments, in a knurled grip.
  • two nuts 27 are arranged on the screw 27, which nuts 27 are flanked and define a stable stop element.
  • the elements 23, 24 are interposed between the nuts 27 and the nut screw 19 and are pushed towards one another by a spring 26 having a first end which abuts, directly or indirectly, on the second element 24 and another end which abuts on one of the two nuts 27.
  • the spring 26 is compressed and distances the second element 24 from the nuts 27 and, therefore, compacts the two elements 23, 24 to one another, forcing them to take on a predetermined reciprocal angular orientation, defined by the conformation of the surface 25.
  • the screw 18 in the mounted configuration also passes through a strike portion 28 defined by a projection of the spray tube 3 and, in more detail, by a projection of the concave body 12a.
  • This projection which is slot-shaped, defines a stop element for the spring 26.
  • the spring as before in the compressed state, nears the first and the second elements 23, 24 to one another, forcing them to take on a predetermined reciprocal angular orientation, defined by the conformation of the surface 25.
  • a cam follower 20 is eccentrically connected to the second element 24, by means of a connecting organ 21, 22.
  • the connecting organ comprises a first lateral arm 22a of a support bracket 22 which exhibits a second lateral arm 22b, parallel to the first and engaged restingly on the screw 18.
  • the connecting organ comprises a connecting rod 21 which is solidly connected to the second element 24 and which extends transversally of a rotation axis of the second element 24, such that to a rise or fall of the cam follower 20 corresponds a rotation of the second element 24 with respect to the first element 23.
  • the cam follower 20 is arranged such as to roll along a curved trajectory which develops about a rotation axis X of the spray tube 3 and which is defined by the guide surface 17.
  • the cam follower 20 is rotatable about a respective rotation axis Y which preferably passes through a reciprocal screwing axis of the two elements 23, 24 and which assumes a variable orientation according to the portion of the guide surface 17 at a given moment engaged by the cam follower 20.
  • the cam follower 20 changes its position with respect to the spray tube 3, and in particular rotates about the reciprocal screwing axis of the two elements 23, 24 according to the angular position assumed by the spray tube 3 about the rotation axis X.
  • Figures 3 and 4 denote, respectively in a continuous and a broken line, the extreme positions achieved by the cam follower 20 during the rotation of the spray tube 3, to which corresponding extreme inclinations of the rotation axis Y of the cam follower 20 relate.
  • the guide surface 17 exhibits an undulated profile, i.e. having a height (measured along a parallel direction to the rotation axis X of the spray tube 3) which is continuously variable along the angular range covered by the spray tube 3 during the rotation thereof.
  • the guide surface 17 has a conformation which determines a progressive lowering of the cam follower 20 up to reaching an intermediate position between the extreme positions, and such as to determine a successive rising of the cam follower 20 from the intermediate position towards the second extreme position.
  • This conformation of the guide surface 17, which can be described as a dropping of the guide surface 17 into a central position thereof, determines a corresponding movement of the cam follower 20 which in turn and in cooperation with the surface 25 defined by the two elements 23, 24, causes a reciprocal distancing and/or a nearing of the two elements 23, 24.
  • This causes a variable locking force on the terminal portions 11b of the collar 11 and, consequently, a variable braking force on the spray tube 3.
  • a rotation of the second element 24 generates a compression of the spring 26 with a consequent thrust on the nuts 27 to distance them from the second element 24. This thrust tends to near the two terminal portions 11b to one another, with an increase of the locking force on the collar 11.
  • the presence of the spring 26 tends to keep the two elements 23, 24 against one another and this configuration corresponds to the central portion of the guide surface 17, i.e. the lowered portion, while the rise of the terminal tracts of the guide surface 17 causes a rotation of the command organ 21, 22 and thus a rotation of the second element 24, opposed by the thrust of the spring 26.
  • the spring 26 thus keeps the cam follower 20 continuously pushed against the guide surface 17.
  • the above-described irrigator 1 is advantageously installable on a trolley, not illustrated in the figures, to move the irrigator 1 along a predetermined irrigation trajectory.
  • the trolley might be drawn by the same flexible tubing used for connecting the irrigator 1 to the water source, in particular a dispenser. This can be obtained by means of winding the flexible tubing on a coil reel, and by means of programmed motorisation of the coil reel in order to displace the position thereof at regular time intervals.
  • the present invention attains the set aims and obviates the cited drawbacks in the prior art.
  • the possibility of automatically varying the rotation velocity of the spray tube enables a reduction in the quantity of water dispensed towards the central zones of the terrain to be irrigated (or, more exactly, the water directed towards the central zone of the angular sector covered by the rotation of the spray tube, which extends through about 180 degrees) and also enables the quantity dispensed towards the lateral zones to be increased.
  • the intermediate element and the metal plate define dragging braking means, which reduce the braking action between the base and the spray tube.
  • the guide surfaces, the cam follower and the locking means define means for continuously regulating the braking action, and are directly active on the braking means in order to continuously vary the contact pressure between the plate and the intermediate element and, therefore, the rotation velocity of the spray tube. This variation is obtained automatically, i.e. exclusively according to the angular position taken on by the spray tube about the rotation axis.
  • the undulating or curved conformation of the guide surface reduces the stresses to which the spray tube (and the whole irrigator) is subjected during the braking stages of the rotation. Also, the braking stress is distributed along the whole development of the collar, which extends almost entirely through 360°, with small wear on the collar and/or the underlying intermediate element. The braking element is thus regulated continuously, thanks to the described curved conformation of the guide surface.
  • Figure 8 is the pluviometer diagram of the irrigator of the present invention.
  • the curve obtained illustrates a flattening of the central zone, showing uniformity of water distributed over the terrain. This leads, as a further advantage, to a reduction in waste of water, to the benefit of the vegetation on the terrain.
