    Interchangeable cover device in greenhouses that is constituted by two sheets, one of transparent plastic (5) and another consisting of a mesh (6), the first of them related through one of its edges with a fixed profile and top (4) ) and the second with the winding/unwinding axis (9) of the other end of the plastic sheet, with the special feature that said axis (9), considered as primary, is driven by a motor (8) sliding on some lateral guides, to produce the winding/unrolling of the plastic sheet (5) and simultaneously the unwinding/winding of the mesh (6).

    OBJECT OF THE INVENTION
    The present invention relates to an interchangeable cover device in greenhouses, and more specifically to a system that makes it possible to exchange the selective arrangement between two sheets in the same greenhouse cover, to allow indoor ventilation preventing the entry of birds and insects, or to prevent the entry of rainwater or humidity.
    BACKGROUND OF THE INVENTION
    As is known, a structure participates in a greenhouse as a support for a roof and plastic sides, based on resistant sheets that allow the total entry of light.
    These plastic sheets have to withstand very varied temperatures, both very high and very low, so that changes in atmospheric conditions can affect the normal development of fruit and vegetable products inside the greenhouse, being necessary sometimes to have to refold these sheets to allow ventilation and reach the optimum temperature inside.
    Although there are systems for the folding of this type of sheets, they only fold said plastics in an automated way, leaving the spaces covered by them uncovered, which facilitates the entry of birds, insects and the like that could damage the products that They are being raised in the greenhouse. DESCRIPTION OF THE INVENTION
    The device that has been recommended has been conceived to solve the problem described above, in a simple way but with great efficiency.
    For this, the device of the invention allows to alternate between a plastic enclosure, providing all the typical characteristics of a greenhouse, or convert the enclosure into a mesh surface, anti-insects and birds, allowing adequate ventilation without risk of entry of This kind of animals.
    Based on this concept, it is evident that in the device of the invention two cover sheets participate, one with a closed and transparent surface, as is conventional, and another that defines a mesh, so that when one is rolled the other is unwound , being able to establish intermediate positions, in which the surface, which will always be covered, is partially covered by one or another type of cover, allowing greater durability of the materials used, since when they are not being used, they are collected, with a sensor less exposure to the weather.
    More specifically, the device of the invention is based on the fact that the enclosure consists of two sheets, a primary and transparent plastic, roll-up and unwind with respect to an axis driven by a motor, which is sliding through a guide provided in the profile of each of the sides of the arch of the greenhouse, being related to said primary axis of winding / development of the primary plastic sheet, a mesh, associated with a tensioning device that can be extended or deployed, to form the enclosure, when the transparent plastic sheet is rolled or extended, respectively.
    In this way, it is achieved that the enclosure can be constituted alternately and interchangeably, both the transparent plastic sheet, avoiding the internal ventilation of the greenhouse, or arrange a mesh that allows the ventilation of the greenhouse preventing the entry of insects and birds . DESCRIPTION OF THE DRAWINGS
    To complement the description that will then be made and in order to help a better understanding of the features 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 1 shows a representation corresponding to a perspective view of an interchangeable cover device in greenhouses made in accordance with the object of the invention.
    Figure 2.- Shows a profile view of the assembly of the previous figure. PREFERRED EMBODIMENT OF THE INVENTION
    As can be seen in the aforementioned figures, the device of the invention is applicable to a greenhouse with pillars (1) and profiles (2) as arch elements that form part of the general structure of the greenhouse, which is complemented by a gutter (3), as is conventional, for rainwater collection, and with a superior-posterior profile
    (4) as a fastening element of the rear edge corresponding to a transparent plastic sheet (5) that will constitute the enclosure of the greenhouse itself, also including a second sheet, in this case constituted by a mesh (6), which Like the previous one, it is roller / unrolling, in the opposite way, that is to say that when the plastic sheet (5) is extended then the sheet or mesh (6) is collected and vice versa.
    On the arches (2) a guide (7) is provided by which a motor-reducer is sliding
    (8) for driving a primary shaft (9) on which the plastic sheet (5) is wound and unrolled, while the mesh (6) is wound and unwound at its lower end with respect to a secondary shaft (10) mounted on a box (11), so that associated with the secondary axis (10) of winding / unwinding of the mesh (6), a tensioner is provided
    (12) related to a counterweight (13), also including an adjustment bar (14) and a
    reinforcement (15) for said bar.
    That is to say, the elements corresponding to the tensioner (12), with the counterweight (13) and the adjustment bar (14) with the reinforcement (15) allow to maintain the tension of the secondary axis 5 (10) of mesh reinforcement ( 6).
    Well, from these characteristics, the operation is as follows:
    Finding the plastic sheet (5) unfolded, and therefore collecting the mesh (6), the
    When the engine is started (8), it carries its sliding along the guide rail (7), rotating the primary shaft (9) and therefore gradually winding the plastic sheet (5) on that primary axis (9), so that the mesh (6) is deployed, being connected by one of those edges to the primary axis (9) that will pull it and deploy it so that the greenhouse enclosure can be ventilated.
    However, when the shaft (9) by motor drive (8) is in the rear or raised position, the mesh (6) constituting the enclosure as just described, for the exchange of the type of enclosure, that is to say replace the mesh (6) by the plastic sheet (5) just drive the motor in the opposite direction, sliding along the guide (7)
    20 so that the shaft (9) is unrolling the plastic sheet (5) and wrapping the mesh (6).
    Obviously an intermediate conversion can be established, that is to say that the plastic sheet (5) and mesh (6) are partially folded / unfolded.
