Description [0001] The invention relates to a protective device of a dispenser supply hose. Such a protective device is known, for example, from US 4 756 260 A. It is a further object of the present invention a fluid feeding system provided with said protective device.

[0002] The invention finds application in the field of agriculture and forestry and in all those sectors wherein irrigation via a fluid is required.

[0003] By fluid it is meant water, sewage, animal waste and wastewater from the central bioenergy.

[0004] Within the agricultural field, irrigation systems are known which comprise a winding-reel of a fluid supply hose, which supply hose is connected to a dispenser.

[0005] The dispenser is fitted aboard a trolley which is being moved on the soil to be irrigated.

[0006] The winding-reel and the trolley carrying the dispenser are generally arranged opposite to one another. In other words, while the winding-reel is arranged on a side of the soil to be irrigated, the trolley is fitted aboard the dispenser which is initially arranged on the side opposite to that where the winding-reel is situated.

[0007] As the irrigation cycle proceeds, the trolley is drawn towards the winding-reel for moving along the soil to be irrigated.

[0008] Thus, a preparatory step as well as an operational step are provided within a soil watering cycle.

[0009] During the preparatory step, both the winding-reel and the trolley are positioned. During this step, the trolley is arranged in a position opposite to that of the winding-reel via an agricultural tractor. In other words the agricultural tractor causes the trolley to move from a starting end (where the winding-reel of the hose is placed), up to the opposite end of the soil to be treated. This towing step of the trolley further involves unwinding of the supply hose initially wound on the winding reel.

[0010] In the operational step of the feeding system the trolley is gradually recovered by the winding-reel, which winding-reel becomes wound on itself so that the dispenser may start wetting the soil to be irrigated.

[0011] Thus, during the preparatory step, the trolley and the dispenser are operated via the agricultural tractor which provides to tow them, whereas during the operational step, the trolley and the dispenser are recovered via rewinding of the supply hose on the winding reel.

[0012] It is known that irrigation systems as the one disclosed above by way of example, exhibit some drawbacks often affecting the supply hose, which drawbacks generally result in serious complications such as rupture of the supply hose with consequent dispersion of water in pressure.

[0013] A first drawback is due to the fact that during irrigation the supply hose is subject to damage, when not to complete rupture, because of an excessive friction occurring between the supply hose in its stretched condition and the soil. The friction between the hose and the soil particularly depends on the type of crop as well as on the type of soil. Indeed, on farmlands with low-stem plants, such as for example potatoes or beet and the like, in the case where the field was cultivated with non-irrigated forage immediately after mowing operations, between the outer wall of the supply hose and the leaves of the plants, there is generated a high friction such that the supply hose becomes subject to a localized and concentrated traction often resulting in rupture of the supply hose. Hence, irrigation on lands farmed with low-stem plants which are rich in leaves, leads to mechanical stress of the supply hose.

[0014] A further aspect which determines drawbacks within the irrigation systems of the prior art is related to the very nature of the soil, indeed according to the geographical position of the farmland, for example an agricultural plain area rather than an agricultural mountain area, wherein the terrain is smoother and dustier, a different amount of clay and/or sand is likely to be found.

[0015] Where a high sand quantity is present in the soil, this results in a premature wear of the outer surface of the supply hose due to permanent abrasion exerted by the sand on the hose. This abrasion subsequently results in a thinning of the hose thickness to the detriment of the fluid mechanical seal to the pressure, with consequent rupture of the hose itself.

[0016] Where the soil is clayey, the situation further deteriorates in the event of rain due to which a very strong adhesion, almost a gluing of the hose to the soil occurs.

[0017] The friction resulting from the hose being towed on the ground, then causes dragging of the machine and in some cases even tipping thereof, with consequent loss of stabilization.

[0018] Because of friction, mechanical failure of transmission organs or structural ruptures of the hose winding-reel may also occur.

[0019] It is an object of the present invention to provide a protective device able to overcome the drawbacks encountered in the known art as above disclosed.

[0020] Thus, aim of the present invention is to provide a protective device of a dispenser supply hose owing to which reliability and robustness of the supply hose can be improved.

[0021] The above and other aims are substantially attained by a protective device in accordance with what is disclosed in one or more of the appended claims.

[0022] Further characteristics and advantages will become more apparent from the detailed description of several non-exclusive embodiments of a protective device according to the present invention. Dependent claims correspond to possible embodiments of the invention.

[0023] Such a description is provided with reference to the appended figures, which are also provided as a non-limiting example, wherein:

Figurel isaschematicviewofafluidfeedingsystem provided with a protective device according to the present invention in an operative use configuration; Figure 2 is a schematic view of a detail of the pro- tective device illustrated in Figure 1 according to the present invention in one embodiment thereof; Figure 3 is a schematic view of a detail of the protective device illustrated in Figure 1 according to the present invention in a further embodiment thereof; Figure 4 is a schematic view of a detail of the protective device illustrated in Figure 1 according to the present invention in a further and different embodiment thereof;

Figure 5 is a schematic view of a further detail of the protective device shown in Figure 1 according to the present invention.

[0024] In reference to the appended figures, by the numeral 1 it is generally signified the protective device of a dispenser supply hose in accordance with the present invention.

[0025] The protective device 1 comprises at least one trolley 4 of the substantially known type, which is provided with a frame 40 and a plurality of wheels 41 for allowing movement of the trolley 4 on a soil 200 to be irrigated.

[0026] Said trolley 4 can be associated to a dispenser 3, the latter being connected to a supply hose 2 provided with a first end 2a, which is in turn connected to the dispenser 3, and a second end 2b spaced apart from the trolley 4 and thus from the dispenser 3.

[0027] The dispenser 3 can be equally a sprinkler, an irrigation bar also known as wing rain, an under-canopy sprinkler or an above-canopy sprinkler or a sewage dispenser.

[0028] The dispenser 3 comprises a dispensing nozzle for spraying fluid 100, water, sewage, animal waste and effluents, originating from bio-energy power plants, through which dispensing nozzle the fluid is spread evenly over an almost semi-circular area.

[0029] The dispenser 3 can be positioned at a distance from a second end 2b of the supply hose 2 in an extension configuration of the supply hose 2. In other words, the dispenser 3 can be positioned at a distance from the first end 2a of the supply hose 2 which is at most equal to the overall length of the hose 2 itself. Preferably, the second end 2b of the hose 2 is connected with a water source such as a well or a supply channel or an aqueduct. Said second end 2b may be connected to a hose-reel 5 of the supply hose 2. At the second end 2b, the supply hose 2 may indeed be wound on the hose-reel 5 or kept free and wound on itself. Since most of the irrigation systems further provide use of a hose-reel 5, reference shall be made thereto hereinafter.

[0030] The hose-reel 5 is configured to allow the supply hose 2 to be extended in conjunction with a translational movement of the trolley 4 which is moving away from the hose-reel 5, and to allow the supply hose 2 to be recovered in conjunction with a translational movement of the dispenser 3 towards the hose-reel 5.

[0031] Preferably, the hose-reel 5 comprises a second winding-reel 5a of the supply hose 2. Preferably, the hose-reel 5 further comprises support means 5b, suitable for supporting the second winding-reel 5a and allowing rotation thereof about an axis "X", which axis "X" is substantially horizontal in a use configuration of the dispenser 3. In addition, the support means 5b are configured for transporting both the dispenser 3 and the trolley 4 even at long distance, such as for example when the same are being transferred from a warehouse following non-use periods, to a farmland 200 to be irrigated. The support means particularly comprises coupling means 5b schematically shown in the appended figures by the reference 6, which coupling means 5b is suitable for coupling the trolley 4 and the hose-reel 5, so that a single transportation thereof is allowed via a motorized vehicle 300 such as an agricultural tractor or the like.

[0032] In accordance with the inventive concept of the present invention, the protective device 1 is configured for operating alternately between an extension configuration of the supply hose 2 and a recovery configuration of the supply hose 2.

[0033] In particular, the extension configuration of the supply hose 2 takes place when the first end 2a is moving away from the second end 2b, whilst the recovery configuration of the supply hose 2 occurs when the first end 2a is moving towards the second end 2b of the supply hose 2.

[0034] In both operational configurations of the device there is provided flowing of water through the supply hose 2, i.e. both if the supply hose 2 is being gradually extended or wound on the second winding-reel 5a.

[0035] In particular, in an extension configuration of the supply hose 2, the trolley 4 and the dispenser 3 fitted thereon are transportable to a pre-determined maximum distance with respect to the hose-reel 5, which distance is preferably determined by the complete unwinding of the hose 2 from the second winding reel 5a.

[0036] Conversely, in a recovery configuration of the supply hose 2, the trolley 4 and the dispenser 3 fitted thereon are brought back to the initial position at the hosereel 5, preferably with the supply hose 2 being recovered on the second reel winding 5a.

[0037] In detail, the second winding reel 5a is configured for rotating idly about the axis "X", so as to allow extension of the irrigation hose 2 in the extension configuration of the supply hose 2 via motorized means 300, which motorized means 300 is suitable for towing the trolley 4 and for rotating in the opposite direction in order that the supply hose 2 can be recovered through an external power source (not illustrated in the appended figures).

[0038] By way of non-limiting example, the external power source may comprise a mechanical power socket connected to a power output of an agricultural tractor, or the external power source may comprise an electrical or endothermic engine which is suitable for causing the second winding-reel 5a to rotate, which electrical or endothermic engine is mounted exactly on the hose-reel 5.

[0039] In accordance with the present invention, the protective device 1 comprises accumulating means 8 of a protective element 9 for the supply hose 2, which accumulating means 8 is associated with the trolley 4 in an operative use configuration of the dispenser 1.

[0040] Advantageously, the accumulating means 8 are configured for interposing the protective element 9 between the soil 200 and the irrigation hose 2 in the extension configuration of the supply hose 2, in order that the protective element 9 is collected from the soil 200 in a recovery configuration of the supply hose 2.

[0041] In other words, the supply hose 2 in a use operational configuration of the dispenser 1 is always resting on the protective element 9, which in turn is lying on the soil 200 which is being irrigated.

[0042] Advantageously, the supply hose 2, in conjunction with its operating unwinding and recovery configurations on the second winding-reel 5a, is not in contact with the soil 200, nor with the plants growing in the soil. By way of example, the appended Figure 1 illustrates schematically the protective device 1 of the present invention in the extension configuration of the supply hose 2 in conjunction with which the hose 2 is resting on the soil 200 only after that the protective element 9 was laid thereon.

[0043] In particular, the protective element 9 is of the flexible type so that it can be unwound and collected by the accumulating means 8 respectively in the extension configuration of the supply hose 2 and in the recovery configuration of the supply hose 2 without any jamming taking place. Preferably the protective element 9 is of the flexible and wind-up ribbon-like type. By way of non-limiting example, the protective element 9 is a plastic strip or a woven mesh made of plastic material, e.g. PP or PE or it can be a cloth made of a non-woven-fabric.

[0044] Preferably, the accumulating means 8 of the protective element 9 comprises a first winding-reel 8a of the protective element 9, as shown schematically in the appended figures. The first winding-reel 8a of the protective element 9 is rotatable about an axis "Y" which is substantially horizontal so that the protective element 9 can be extended/collected in a tangent position to the soil 200.

[0045] The first winding-reel 8a is configured for idly rotating about the axis "Y" so as to allow the protective element 9 to be extended in the extension configuration of the supply hose 2, and for rotating about the axis "Y" in opposite direction in order to allow the protective element 9 to be recovered in the recovery configuration of the supply hose 2 via a power source 10 of the extension and collecting means 8. The power source 10 will be better disclosed in a later section.

[0046] In particular, a free end 9a of the protective element 9 is constrained at the second winding-reel 5a of the hose 2 so that a counter-acting force is generated which allows unwinding of the protective element 9 in the unwinding configuration of the same, as well as extension of the supply hose 2. Preferably the free end 9a of the protective element 9 is constrained directly to a portion of the support means 5b, as shown by way of example in Figure 1 attached hereto. The free end 9a of the protective element may further be constrained to the ground by means of a peg 200 (not shown), or the like.

[0047] Preferably, in an unwinding configuration of the protective element 9 and in an extension configuration of the supply hose 2, the second winding-reel 5a of the hose 2 and the first winding-reel 8a of the protective element 9 respectively rotate idle about the axis "X "and" Y" via a translational movement of the trolley 4 which is moving away from the hose-reel 5, i.e. via a translational movement of the first end 2a connected to the dispenser 3, which first end 2a performs a movement away from the second end 2b connected to the hose-reel 5 of the supply hose 2.

[0048] The accumulating means 8 of the protective element 9 comprises at least one accompanying drum 8b configured to rotate according to a winding direction of the protective element 9 about the first winding-reel 8a in the accumulating configuration of the irrigation hose 2. Preferably, the accumulating means 8 comprises a pair of accompanying drums 8b, still more preferably the accompanying drums 8b are rotatable brush drums with rotation direction opposite to the winding direction of the accumulating means 8.

[0049] Advantageously, the accompanying brush drums 8b are suitable for promoting correct positioning of the protective element 9, especially when the protective element 9 is being wound on the first winding-reel 8a; the brush drums 8b further allow removal of any sand deposits, debris, leaves or grass from the protective element 9, which remained deposited thereon after that the latter was stretched on the soil 200.

[0050] With reference now to the appended Figure 5, the protective device 1 comprises an enabling element 11, which is so configured as to reversibly select rotation of the first winding-reel 8a between an idle rotation, corresponding to the extension configuration of the irrigation hose 2, and a driven rotation through which the protective element 9 is recovered in conjunction with the recovery configuration of the irrigation hose 2.

[0051] The enabling element 11 comprises a pulley 11a which is reversibly movable between an engaged position (dotted line in the illustration of Figure 5), and a disengaged position (solid line in the illustration of Figure 5), wherein the pulley 11 a in the engaged position thereof is engaging and stretching a belt 11b, which belt 11b is predisposed for a mechanical transmission between the power source 10 and the first winding-reel 8a; in this manner the protective element 9 is allowed to be recovered in conjunction with the recovery configuration of the irrigation hose 2.

[0052] In other words, the enabling element 11 is operable in a use configuration of the dispenser 1 for converting the idle rotation of the second winding-reel 5a of the supply hose 2 and the first winding-reel 8a of the protective element 9, in conjunction with the stretching configuration of the protective element 9 and the extension configuration of the supply hose 2, into a driven ro- tation of the second winding-reel 5a of the supply hose 2 and the first winding-reel 8a of the protective element 9 by means of different systems better detailed in a later section.

[0053] Preferably, the pulley 11 a is reversibly movable via an electro-mechanical actuator. In one embodiment of the present invention, not illustrated in the appended figures, the device 1 comprises a rechargeable battery adapted to power the electro-mechanical actuator in which said battery is rechargeable via a photovoltaic panel or an electrical generator driven by a hydraulic turbine.

[0054] In accordance with an embodiment illustrated schematically in figure 2 and 3, the device 1 comprises accumulating means 8, which in turn comprises a power source 10 of the electronic or electro-hydraulic type. Preferably, the power source 10 of the electronic or electro-hydraulic type is configured to exploit respectively electricity or pressure, and flow rate of a fluid 100 in order that the accumulating means 8 can be activated.

[0055] With particular reference to Figures 2 and 3, the accumulating means 8 of the protective element 9 comprises an oscillating lever 12 in a reversible manner, which lever 12 is operatively associated with the power source 10 of the electronic or electro-hydraulic type.

[0056] The oscillating lever 12 is configured for being arranged between a first position reachable by its own weight, so that the accumulating means 8 are activated in a loosening condition between the first winding-reel 8a and the protective element 9 - see dotted line in the appended Figures 2 and 3 - and a second position reachable via a lateral thrust imparted by the protective element 9 which is stretched so that the accumulating means 8 are not activated in a stretching condition between the first winding-reel 8a and the protective element 9 - see continuous line in the illustrations of Figures 2 and 3 annexed hereto.

[0057] In other words, when the winding speed of the protective element 9 is not equal and/or synchronized to the speed of the translational forward movement based on which the trolley 4 is moving towards the hose-reel 5, the oscillating lever 12 activates the power source 10, which in turn sets in rotation the first winding-reel 8a so that the excess of the protective element 9 can be recovered, which tends to protrude relative to the trolley 4 due to a poor winding tension. In conjunction with a correct winding tension of the protective element 9 around the first winding-reel 8a, the oscillating lever 12 becomes subject to a lateral displacement which allows deactivation of the power source 10.

[0058] With particular reference now to Figure 2 attached thereto, in accordance with the present invention, it is illustrated an embodiment of the device 1 comprising a powersource 10 of the electronic type, which comprises an electric motor associated with the first winding-reel 8a and a micro switch 14 operatively associated with a profiled end of the oscillating lever 12. The micro switch 14 is switched to a closed state by means of the oscillating lever 12 in the first position and switched to an open state by means of the oscillating lever 12 in the second position.

[0059] Preferably, the electric engine 13 is powered by a rechargeable battery 15 through a photovoltaic panel 16.

[0060] With particular reference now to Figure 3 attached thereto, in accordance with the present invention, there is illustrated a further embodiment of the dispenser 1 comprising a power source 10 of the electro-hydraulic type which includes a hydraulic valve 17 operatively associated at one end of the oscillating lever 12. The hydraulic valve 17 is switched to an open state with the oscillating lever 12 being in the first position, and to a closed state with the oscillating lever 12 being in the second position thereof.

[0061] The hydraulic valve 17 is in fluid connection with a hydraulic turbine 18 which is mechanically connected to the first winding-reel 8a in such a manner that a mechanical torque, generated by the hydraulic turbine 18, is transmitted to the first winding-reel 8a, so that winding of the protective element 9 is allowed. Preferably, the hydraulic turbine 18 is mechanically connected to the enabling element 11 and the latter to the first winding-reel 8a.

[0062] Preferably, the hydraulic valve 17 is configured for withdrawing the fluid 100 from the irrigation hose 2 in proximity of the dispenser 3.

[0063] With particular reference now to Figure 4 attached thereto, in accordance with the present invention, the dispenser 1 is illustrated, which comprises a power source 10 of the mechanical type. Preferably, the power source 10 of the mechanical type is configured to draw power from the translational forward movement of the trolley 4 towards the accumulation device 5. The power source 10 of the mechanical type particularly comprises a mechanical connection between a free end of the first winding-reel 8a and a drive wheel 19, which is configurable between a contact position with the soil 200 and a rotatable position - shown schematically by the continuous line of the appended Figure 4 - for converting the translational forward movement of the trolley 4 into mechanical power in order that the first winding-reel 8a is set in rotation, and a raised and non-active position, as shown schematically by the dotted line of Figure 4 herewith annexed. Preferably, the mechanical connection between a free end of the first winding-reel 8a and the drive wheel 19 is a flexible chain or belt mechanical transmission.

[0064] The present invention has attained the set aims.

[0065] Advantageously, the protective device allows stretching and winding of the supply hose, wherein the supply hose is maintained in a state of cleanliness suitable for ensuring greater reliability as well as a better service life than the prior art.

[0066] Owing to use of a hose protective element, which completely separates the hose from the soil and the cultivated plants, the protective device of the present invention advantageously allows winding and stretching of the supply hose without any necking and/or excessive friction being formed due to contact with the soil or the foliage of cultivated plants, even when the soil or the foliage are wet.

[0067] Owing to the protective element which isolates consistently the irrigation hose from the bearing surface, the device of the present invention advantageously allows to effectively irrigate any type of soil, regardless if sandy, clayey, dusty or stony.

[0068] The protective device of the present invention advantageously allows to protect the supply hose with the aid of means partially or completely independent from an external power source, thereby resulting use of the dispenser simple, efficient and cost-effective.

[0069] Advantageously, the protective device of the present invention improves smoothness of the hose on the soil, thereby promoting a reduced waste of energy of the fluid feeding system during rewinding of the supply hose, as well as an under-sizing of the driving means fitted aboard the hose-reel.
