    专利说明:

    [0001] The present invention relates to a multiple-nozzle support assembly with increased operational flexibility.
    [0002] Sprinkler machines for the controlled distribution in crops of plant protection products, such as liquids for fertilizer treatments, herbicides, fungicides, insecticides and the like, are known in the field of agriculture.
    [0003] Such sprinkler machines are generally affixed or towed by a tractor that follows a pre-established path throughout the cultivation, so that the treatment carried out covers its entire length, and are essentially constituted by a structure that supports a tank to store the working liquid, which, by means of a pumping assembly, offers one or more distribution bars, along which there are a plurality of holes for the discharge of the liquid, to which adapted atomizing nozzles are applied by interposing supports of matching nozzles.
    [0004] Each nozzle holder comprises a main body for coupling to the distribution bar, which is provided with an inlet for the working liquid that is adapted to be connected to the outlet hole of the distribution bar and one or more outlets that they can be attached to mating nozzles via threaded connections or quick coupling systems such as a bayonet coupling. The inlet and each outlet are mutually connected by means of a duct for the passage of the working liquid, which, in some types of nozzle holders, is sectioned by a membrane-type or similar flow control valve, with electromechanical actuation or pneumatics, which, through a remote control system, makes it possible to manage the opening or closing of the outlet in relation to the work parameters that have been established or detected.
    [0005] It should be considered that, according to current spraying techniques, the type of nozzles to be used must be selected depending on the work parameters, in order to achieve an ideal droplet size that allows avoiding so much deviation and the dripping of the sprayed liquid. Drift phenomena occur when droplets of atomized liquid are too small (usually less than 100 µm in size) and therefore run the risk of being blown out of the area to be treated, with consequent risks of dispersing substances harmful by the surrounding environment. Furthermore, excessively small droplets penetrate the soil with greater difficulty. In contrast, dripping phenomena occur when the liquid droplets coming out of the nozzles are too large (usually with a size of more than 800 µm) so that they tend to fall too close to the spray point, without reaching the spray point. optimal distribution of liquid in the area to be treated.
    [0006] For these reasons, it is of fundamental importance to carry out a focused selection of the nozzles to be used and to adjust the operating parameters as a function of the treatment to be carried out, in order to maintain the size of the dispensed drops within the ideal values, also in view of the physicochemical characteristics of the liquid to be distributed.
    [0007] In particular, once the volume of liquid to be distributed over a given area has been defined and the maximum operating pressure of the sprinkler machine is known, as the speed of travel of the tractor varies, the flow rates that must be delivered by the nozzles change in a directly proportional way, while the pressure varies in proportion to the square of the flow rate. Due to these variations in working parameters, therefore, it may be convenient to modify the type of jet in use, in order to achieve an ideal droplet size and at the same time stay within the range of pressures allowed by the spray machine, or use a nozzle type with a spray pattern that is more suited to the type of treatment being performed (eg a fan-like pattern rather than a cone-shaped one, or vice versa).
    [0008] For these reasons, nozzle holder solutions have been developed that allow you to select the type of nozzle in use from a range of nozzles installed directly on the nozzle holder.
    [0009] In this sense, for example, a type of nozzle support is known that has a single output, with the possibility of selecting the nozzle associated with it. In that case, the nozzle holder has an additional body which is associated, so that it can rotate through various operational configurations, with the main coupling body and is provided with a plurality of holes adapted to be connected alternately to the output in operational configurations corresponding to each of which a different nozzle type is associated. The operator, therefore, must select the most appropriate mouthpiece, based on his experience and on the data provided by the manufacturers, depending on the operational parameters of the treatment to be carried out.
    [0010] However, this solution relies the satisfactory result of the treatment solely on the precision of the selection made by the operator and requires that the travel speed of the spray machine be maintained throughout the execution of the work within a range of values that are adequate for the type of mouthpiece that is used.
    [0011] As an alternative, there is also a more sophisticated solution that consists of a double nozzle support, that is, provided with two outlets, each of which is associated with a corresponding nozzle and is provided with a corresponding membrane valve for opening or selective closing. The remote control system is programmed to manage, depending on working conditions, the actuation of the membrane valves to close or open so as to achieve liquid discharge only from the most appropriate nozzle, or from the two nozzles in parallel, for each support of nozzles.
    [0012] However, this solution has the disadvantage that, for treatments that require very different distribution volumes, it is necessary to replace the pair of nozzles mounted on the nozzle support, with a waste of time on the part of the operator.
    [0013] In order to partially obviate these disadvantages, there is an even more sophisticated solution that consists of a quadruple nozzle support, that is, equipped with four outlets, each of which is associated with a corresponding nozzle and is equipped with a valve of corresponding membrane for selective opening or closing. In this case too, the remote control system is programmed to manage, depending on the working conditions, the actuation of the membrane valves to close or open in order to obtain liquid discharge only from the most appropriate nozzle, or a combination of nozzles in parallel for each nozzle holder.
    [0014] Although this solution is ideal in terms of effectiveness, it is too large and too expensive due to the large number of components required (in particular a valve and corresponding actuation systems for each outlet) for many applications, which in any Therefore, they require the opening of one or a maximum of two outputs in parallel.
    [0015] In addition, in some applications this solution cannot be installed due to the occupation of space, mainly constituted by the flow control valves and the corresponding actuation systems.
    [0016] The purpose of the present invention is to eliminate the above-described disadvantages of the prior art by designing a multiple-nozzle support assembly with increased operational flexibility that allows for ensuring the possibility of selecting among different types of nozzles, or combinations of nozzles, to be used for correct control of drop sizes, which contains the number of components and hence the total cost and space occupation.
    [0017] Within that purpose, a purpose of the present invention is to limit the number of interventions required by the operator and, in particular, not require the direct intervention of the operator to replace the nozzle in use whenever the working parameters, such as the tractor travel speed change.
    [0018] Another objective of the present invention is to ensure the possibility of preventing accidental leakage of the working liquid in inactive conditions, even in the event of failure or defect of the check valves with which the sprinkler machine is provided.
    [0019] Another purpose of the present invention is to provide a structure that is simple, relatively easy to provide in practice, safe to use, effective in operation and relatively low cost.
    [0020] This purpose and these and other objectives, which will become more evident later on, are all achieved by the present multi-nozzle support assembly with increased operational flexibility, comprising a main body provided with an inlet for a working fluid and at least two outlets for said fluid, the inlet having a fluid connection to each outlet through a respective passage duct that is sectioned by corresponding valve means for flow control with automatic actuation, characterized in that that it comprises an additional body provided with at least three couplings for connection to respective atomizing nozzles, which is associated with said main body so that it can move through various operational configurations, at least two of which are delivery configurations in the which selectively at least two of said at least three couplings each have a fluid connection to one of said at least two outputs.

    [0036] In particular reference to the Figures, numeral 1 generally designates a multi-nozzle support assembly with increased operational flexibility.
    [0037] The nozzle support assembly 1 comprises a main body 2 provided with at least one inlet 3 for a working fluid and with at least two outlets 4, wherein the inlet 3 and each outlet 4 are mutually connected by means of a respective duct 5 for the passage of the working fluid which is sectioned by corresponding valve means 6 for flow control with automatic actuation.
    [0038] Typically, the valve means 6 are of the type of conventional membrane valves, however flow control elements that have a different shape may also be provided.
    [0039] Each of the valve means 6 comprises an essentially cylindrical valve body 7 in which there is an annular chamber 8 for the inflow of fluid and an axial duct 9 for the discharge of said fluid, both of which pass through the body. valve 7 and are open at corresponding mutually opposite ends.
    [0040] A first end of the valve body 7 is associated with the main body 2 so that the annular chamber 8 and the axial duct 9 are connected to respective portions of the corresponding passage duct 5, one of which comprises the inlet 3 and the another that understands output 4.
    [0041] A second end of the valve body 7, arranged opposite the previous one, is associated with a membrane-type flow control element 10, which covers the open ends of the annular chamber 8 and the axial duct 9 and can be alternatively move between a closed configuration (Figures 7a and 9a), in which it is pressed against the end of the valve body 7, preventing the passage of working fluid from the annular chamber 8 to the axial duct 9, and an open configuration (Figures 7 and 9), in which it is separated from the end of the valve body 7 so as to allow the passage of fluid from the annular chamber 8 to the axial duct 9.
    [0042] Each of the valve means 6 comprises automatic means 11 for actuating the membrane 10 between the open and closed configurations, which are not described in detail as they are of a conventional type and are actuated by a remote control system for the management of spray treatment of a known type.
    [0043] The actuation means 11 can be, for example, of the pneumatic type 11a or of the electromechanical type 11b.
    [0044] In the illustrated mode, the fluid passage ducts 5 related to each outlet 4 coincide, at first, in the inlet 3, and merge in a chamber 12 to collect the working fluid, which is defined inside the main body 2 and is connected to the annular chambers 8 of the two valve bodies 7, which are provided in one piece with said main body, whereas they are distinct downstream of the valve means 6 to the respective outlets 4.
    [0045] Furthermore, for the use of the nozzle support assembly 1 in sprinkler machines of the known type, means 13 for coupling to a distribution bar of a sprinkler machine, not shown, are provided and are associated with the body main 2 so that inlet 3 can be arranged in fluid connection with an outlet hole for the working fluid defined in said bar.
    [0046] The coupling means 13 comprise, for example, an arc-shaped arm 14 having one end that is hinged to the main body 2 near the inlet 3 and the opposite end that can be temporarily connected to said main body by means of of a screw 15 which is engaged in a through hole defined in the arm 14 and in a corresponding threaded blind hole defined in the main body 2, so as to secure the distribution bar between the arm and the main body so that the inlet is directed to the corresponding output hole.
    [0047] In particular, the main body 2 is provided in two parts: a first part 2a, which comprises the inlet 3 and the first portion of the passage duct 5 which is common to the two outlets 4, and a second part 2b, in which the valve bodies 7, the end portions of the passage ducts 5 and the outlets 4, mutually connected by means of connecting elements by obstacle, are defined.
    [0048] The first part 2a has a tubular portion 26 which is hermetically inserted into a corresponding casing 27 defined in the second part 2b, which are mutually connected by means of a first fork 28, whose pins are inserted through first through holes 29 defined in casing 27 and are accommodated in corresponding grooves 30 formed laterally in tubular portion 26.
    [0049] The nozzle support assembly 1 additionally comprises an additional body 16 provided with at least three couplings 17 for connection to respective atomizing nozzles U, which is associated with the main body 2 so that it can move through different configurations operating systems, of which at least two are for delivery and in which selectively two of the at least three couplings 17 each have a fluid connection to one of the outputs 4.
    [0050] A U-nozzle of a different type, suitable to be used in different operational configurations to obtain optimal drop size control, can be applied to each coupling 17.
    [0051] The couplings 17 can be of the threaded type or can serve for quick coupling systems, depending on the type of U-nozzle to which they will be coupled.
    [0052] Conveniently, there are watertight elements, of the type of conventional sealing rings 31, between the main body 2 and the additional body 16 at each outlet 4.
    [0053] Preferably, the main body 2 and the additional body 16 are coupled by means of a swivel coupling, the additional body 16 being able to rotate relative to the main body 2 by the various operational configurations around a geometric axis of rotation. In this case, the couplings 17 are distributed along a circumference that is centered on said geometric axis of rotation and are separated in pairs so that they can be positioned alternately on the outputs 4 in the active delivery configurations.
    [0054] This solution allows to optimize the space occupation of the nozzle support assembly 1. Alternatively, as far as allowed by the space occupation limitations provided by the specific application, the additional body 16 can be associated so that it can slide reciprocally with the main body 2.
    [0055] The nozzle holder set 1, therefore, can assume different configurations depending on the number of inputs 3, outputs 4 and couplings 17 provided.
    [0056] Typically, but not exclusively, the nozzle holder assembly 1 may provide one input 3, two outputs 4 and three or four couplings 17.
    [0057] In the case of three couplings 17 distributed on a circumference which is centered on the geometric axis of rotation of the additional body 16 and mutually angularly separated by 120°, it is possible to provide up to three active delivery configurations in which the two outputs 4 are alternatively connected to a pair of consecutive couplings 17.
    [0058] In the case of four couplings 17 distributed on a circumference which is centered on the geometric axis of rotation of the additional body 16 and mutually angularly separated by 90°, it is possible to provide up to four active delivery configurations in which the two outputs 4 are alternatively connected to a pair of consecutive couplings 17.
    [0059] Advantageously, there can be at least one additional operational configuration to stop the flow, in which the outputs 4 are not connected to any of the couplings 17. This solution allows to avoid accidental leakage of working fluid in case of defect or failure of the valve means arranged upstream of the nozzle support assembly 1, for example in the sprinkling machine.
    [0060] In the embodiments shown, the additional body 16 is provided with four couplings, but there are two active delivery configurations in which the outputs 4 are alternatively connected to a first pair or a second pair of consecutive couplings 17, both of which active delivery settings are mutually angularly offset by 180°.
    [0061] This is because the axis of rotation of the additional body 16 is inclined relative to the direction of discharge of working fluid from the pair of couplings 17 with a fluid connection to outputs 4 in each active delivery configuration.
    [0062] If the geometric axis of rotation of the additional body 16 is parallel to the working fluid discharge direction (i.e., vertical with respect to Figures 4 and 5), up to four active delivery configurations, offset by 90°, can be provided.
    [0063] The additional body 16 comprises a disc 18 which is perpendicular to the geometric axis of rotation of said body and has a first face 18a which is directed towards the main body 2, of which a rod 19 which has a circular cross-section and is centered on said geometric axis it projects and is pivotally inserted in a corresponding seat 20 provided in the main body 2, and a second face 18b, which is arranged opposite to the previous one, from which the couplings 17 project. Disc 18 has through holes 21 between the first and second faces, respectively 18a and 18b, in each coupling 17.
    [0064] The main body 2 comprises a perimeter band 22 to contain the disc 18, which has a pair of stiffening tabs 23 that project in a radial direction and are diametrically opposite and are retained between corresponding wings 24 that project from the band 22 and the rear wall 25 of the main body 2. This solution prevents flexing of the disc 18, which can cause accidental leakage of the working fluid, to occur.
    [0065] The main body 2 and the additional body 16 are further restrained in an axial direction by means of a second fork 32, whose pins are inserted through second through holes 33 provided in the base of the main body 2 and are accommodated in a groove circumferential 34 which is defined on the rod 19 to allow rotation of the additional body relative to the main body.
    [0066] Advantageously, there is a reversible means 35 to lock the rotation of the additional body 16 relative to the main body 2 in one or more of the active configurations, preferably in all said configurations.
    [0067] Said reversible means 35 comprises at least one pawl 36, which is associated with the rod 19, normally projects in a radial direction with respect to it and can alternately move between said projection position and a retraction position in which it is inserted into a corresponding recess 37 provided in said rod, remaining inscribed in its contour, and at least one corresponding cavity 38 which is defined in the side wall of the seat 20 to accommodate the tongue 36 in a projection position so to restrict the rotation of the additional body 16 with respect to the main body 2.
    [0068] Conveniently, the pawl 36 and the cavity 38 have corresponding contact surfaces that are inclined in the direction that allows the return of said pawl to the retracted position in a first direction of rotation of the additional body 16 relative to the main body 2 and prevents return in the complementary rotation direction.
    [0069] Preferably, the reversible means 35 is provided with two tongues 36, which, as mentioned above, are arranged on the rod 19 in diametrically opposite positions, two corresponding recesses 37 on the rod 19 and at least one pair of corresponding cavities 38 on the seat 20 in at least one of the active configurations.
    [0070] In the embodiment shown, the pawls 36 are provided in one piece with the additional body 16 made of molded plastic material and are connected to the rod 19 by means of respective flexible plastic edges 39, which return them to the projection position . In particular, there is a first pair of cavities, designated by reference numeral 38a, in which pawls 36 engage the two active delivery configurations, and a second pair of cavities, designated by reference numeral 38b, in which pawls 36 they engage in the active setting to stop the flow, which is angularly separated by 45° from the previous one. With particular reference to Figures 12 to 14, the shape of the tabs 36 and the corresponding cavities 38a, 38b is such as to allow rotation of the additional body 16 relative to the main body 2 in a clockwise direction and prevent it in a counterclockwise direction.
    [0071] The operation of the present invention is direct from the above description.
    [0072] In particular, depending on the treatment to be performed, the operator selects the correct active delivery configuration, that is, which pair of U nozzles to be connected to outputs 4, based on the indications provided by the manufacturer.
    [0073] Establishing the U nozzles in use in the remote control system, it is the system itself that controls the actuation means 11 to achieve the opening or closing of the valve means 6 in order to select the most appropriate U nozzle to from which the working fluid must be delivered or optionally opening both so as to obtain a parallel flow from both U nozzles, depending on the values of pressure and travel speed of the spraying machine, which are detected in a way. to achieve correct drop size control.
    [0074] If the sprinkler machine is not used or becomes defective, the nozzle support assembly 1 can be temporarily arranged in the active configuration to stop the flow.
    [0075] In practice, it was concluded that the described invention achieves the proposed purpose and objectives and, in particular, it emphasizes the fact that the nozzle support set according to the invention allows to increase the possibility of selecting the nozzles to be used and the flexibility of use in relation to single nozzle holders equipped with different nozzles or to double nozzles, without involving the structural complexities and cost and space occupation increases that are typical of quad nozzle holders.
    [0076] In particular, the nozzle holder according to the invention allows to achieve the following advantages: in relation to single nozzle holders, the ability to apply an automatic selection of the nozzle in use by means of a remote control system; in relation to dual nozzle holders, an increase in the possibility to select from several pairs of nozzles directly available on the nozzle holder itself; and compared to quad nozzle holders, significant cost savings and space occupation for all applications that do not require more than two nozzles open in parallel.
    [0077] In addition, the multiple support for nozzles according to the invention allows to avoid the risk of accidental leaks of working fluid, which are potentially harmful or polluting, in situations of non-use or defect of the sprinkler machine.
    [0078] The invention thus conceived is susceptible to numerous modifications and variations, all of which are within the scope of the appended claims.
    [0079] All details can additionally be replaced by other technically equivalent elements.
    [0080] In practice, the materials used, as well as the contingent shapes and dimensions, can be any according to the needs without thereby abandoning the protective scope of the appended claims.
