    AGRICULTURAL PLASTICS EXTENDING MACHINED E S C R I P C I Ó N OBJECT OF THE INVENTION
    The present invention relates to a machine that extends agricultural plastics, whose obvious purpose is to carry out the "on-site" deployment of plastic coils with the means for incorporating ballast in their side bands, normally used in agricultural work, such as the covering of the horses of the asparagus crops, leaving the plastic sheets at the same time correctly ballasted, placed and fastened with great comfort and maximum time efficiency. BACKGROUND OF THE INVENTION
    In the agricultural sector, and in certain crops it is necessary to spread plastic sheets on the horses to protect the plants, which is done by machines that can be autonomous or dragged by a tractor vehicle, but which in any case are machines of low performance, functionally unreliable and prone to numerous breakdowns and, of course, frequent incidents in terms of functionality, which forces to make stops continuously, or at least frequently, with the low performance that this implies. DESCRIPTION OF THE INVENTION
    The agricultural plastics spreader machine that is recommended solves in a completely satisfactory way the above-mentioned problem, so that based on a metal structure with wheels for its displacement and equipped with hooking means to a towed tractor vehicle, it has the particularity that in correspondence with the back, in relation to the direction of the paver's movement, it includes a plastic sheet coil, conveniently mounted between brackets arranged telescopically to be able to mount coils with greater or lesser width and even the arms that form The support assembly is assembled in an articulated manner to allow its folding and lifting, in order to conveniently adjust to the desired width and height for the coil, said arms being mobilized, both axially and vertically, by a preferably pneumatic system.
    From the coil located subsequently to the front of the structure, a series of support rollers for the sheet intended to be extended on the ground are provided, so that the front part includes a front roller in which the plastic sheet to extend undergoes a change of direction, being ascending from said front roller, to a front upper roller, in which it changes direction again and returns backwards, being supported by crossbars located in said upper part of the structure, to reach a rear roller mounted on lateral arms with the possibility of mobility so that from it, the sheet falls and is extended on the ground, specifically on the caballón to cover.
    In windy cases, the travel of the coil will be to the contrary, that is, from the support of the coil, the sheet will go up until reaching the rear roller mounted on the side arms, to run along the upper crossbars, to reach the upper front roller , and from it run down until reaching the lower front roller, and after this go through the lower rollers to settle or rest on the ground and extend along the corresponding caballón.
    The structure is mounted on two pairs of wheels, one front and one rear, so that the front or front wheels are removable so that when it is attached to the tractor, the structure is slightly raised from the ground and is supported only on the wheels later, being these telescopic to adapt to different slopes and leveling of the terrain.
    Laterally, the structure has two platforms for operators, which are foldable and deployable, so that in the deployed position they are placed horizontally, so that the operators are standing, while in the folded position they are located attached to the structure itself occupying a minimum volume, or at least smaller width than the original.
    On the sides of the coil are provided bags intended to be filled with a product in ballast functions, so that when resting on the ground the sheet is perfectly extended and unable to move, so that these bags are loaded with the ballast, preferably sand, by the operators, either through a pneumatic gun or through other means, such as a chopping board provided in a storage hopper for the sand constituting the ballast.
    The telescopic means of the rear wheels to adjust height and adapt to the terrain orography, will be complemented with pneumatic means to comfortably raise or lower the structure and set the wheels to the desired height.
    Also say that the plastic sheets used are resistant, being able to be ordered in the market with the desired width and length, according to the needs and preferences of the user, with the particularity that the side bags with the ballast will be filled to measure that the plastic sheet unfolds, before reaching its support on the ground, all of which is done efficiently, quickly and comfortably.
    It should also be said that the coil will be mounted at a low height with respect to the ground, enough so that it does not hit the ground, and yet allows easy assembly, since it can become very heavy and such work must be done manually.
    The rollers in which the plastic sheet slides in its extensibility are free-rotating rollers and are provided to establish a minimum friction of said sheet and which can slide for easy extension, so that said rollers can be replaced by another element that help reduce friction, such as an air mattress, ball bed or other elements such as sheets or rigid sheets, plastic or metal, with the appropriate curvature so that the plastic sheet can slide over them without resistance .
    The rear roller through which the plastic sheet exits before resting on the ground, can be biconic, that is, with a double cone shape, where the two cone sections are joined by their bases, facilitating the adoption of a shape convex on the part of the sheet, helping its correct adaptation to the caballón on which it will be arranged.
    The structure is capable of incorporating boilers for the accumulation of pressurized air, with safety valves and supply with regulation of the air pressure for the different hydraulic mechanisms involved in the device.
    As for the support platforms for the operators, they will have safety railings, allowing the operators to work at the appropriate height, since their height is adjustable, that is, it can be moved vertically and set to the desired height .
    All the elements of the structure are fixed by means of screws, allowing its easy disassembly and anchoring in different positions, offering the greatest possible versatility.
    On the other hand, the gun of compressed air by means of which the ballast bags are filled, can be used alternatively with the function of filling the hopper, so that it can be resupplied with ballast without having to leave the pit, so that in This case will act as a vacuum cleaner, implementing the boiler with a second hose that would function as an aspiration and equipped with a selector stopcock, so that dirt or sand can be collected from the same surrounding soil to be introduced into the hopper.
    Finally, say that in an alternative embodiment, the structure can be adapted in turn to plastic sheets with bags on one side, for which it will have an arm that would rest on the ground and act as a chopping board to provide soil or sand to that side of the plastic band that would thus be buried, so that in this case only one operator would be needed, on the corresponding side, with an air gun on that side. DESCRIPTION OF THE DRAWINGS
    To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

    Figure 6.- Shows a view like the one in the previous figure, but in this case with a reverse path to the previous one, for circumstances in which the wind is strong.
    Figure 7 shows a side perspective view of the itinerary that follows the plastic sheet from the coil until it reaches an area near the exit. PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures, it can be seen how the agricultural plastics spreading machine object of the invention is constituted from a metal structure
    (1) that in its front part includes some points or means of coupling (2) to a towed tractor vehicle, with a pressurized air generator (3) fed by the tractor itself through the cardan, for its accumulation in the corresponding pressurized air boilers (18).
    The structure (1), has a pair of front wheels (4) that are removable, and a pair of rear wheels (4 '), so that when the corresponding tractor vehicle is engaged, the front wheels (4) are removed and the structure corresponding to the spreading machine is supported only on the rear wheels (4 ').
    At a low height and in correspondence with the back of said structure (1) a coil (5) of the plastic sheet (6) to be extended is mounted, so that the path of said plastic sheet (6) from the coil (5) is initially directed towards the front, resting on free-rotating rollers (7), with a roller at the lower front
    (8) in which the plastic sheet (6) changes direction, projecting upwards to a front upper roller (9) from which said sheet (6) is directed backwards supporting on crossbars (10) provided in the upper part of the structure itself (1) of the machine, leaving it to rest on a last roller (11) mounted on articulated, folding and telescopic side arms (12) with the possibility of placing said roller (11) to greater or lower height depending on the needs of each case.
    As for the support wheels (4 '), they are mounted with height-adjustable character so that they can independently be placed at a greater or lesser height and thus adapt to different slopes and irregularities of the terrain, all in collaboration with a pneumatic lifting system of the structure itself (1) to be able to carry out said height adjustment independent of the wheels.
    The machine also includes two lateral platforms (13) for operators, mounted on articulated arms that allow the folding and unfolding of said platform from a horizontal or use position to a vertical or rest position, in which second case the structure will occupy a smaller volume.
    The side platforms (13) are complemented by safety rails (14).
    According to these characteristics, the plastic sheet (6) mounted on the coil (5) has on its sides some plastic bags (15) intended to be filled with a ballast product, such as sand, which is stored in an upper hopper (16), filling by pneumatic guns (17) handled by the operators located on the side platforms (13), although the hopper (16) for ballast product storage includes in its bottom a manually operated chopping board to be able to carry out the filling of the bags (15) without the need for the guns.
    The path of the aforementioned plastic, from the coil (5) to the exit by the rear roller
    (11) mounted on the lateral arms (12), it is optimal when there are no strong winds, in which case the route is made to the contario, that is, from the coil (5) the plastic sheet (6) would reach first place the rear or exit roller (11), would pass through the upper part, in the opposite direction, the one shown in figure 6, then reach the front rollers (9) and (8) to run underneath and exit backwards to be placed on the ground, so that in one case as in another the plastic sheet (6) will be perfectly placed on the ridges and immobilized or held by the ballast loaded in the side bags (15).
    Figures 5 and 6 show the two possibilities of mounting the sheet in its displacement, in the case of absence of wind or soft wind, as well as in the case of strong winds, respectively.
    10 Also say that the arms or supports (19) on which the coil (5) is mounted can be telescopic to adapt properly to different coil sizes, and can also be articulated to allow them to be knocked down or lifted for the same purpose of adjustment, being preferably mobilized by a pneumatic system.
    15 It only remains to point out finally that the exit roller (11) can have a double cone shape joined by their respective bases, that is to say biconic shape, so that the plastic sheet (6) adapts correctly to the ground horse.
