Abstract

Improved greenhouse, which is characterized by regular intervals and above the incurved roof of the greenhouse, and specifically in the sections of descending profile, there are compass tubes, equally curved that are articulated in bearings arranged for this purpose in the curved metallic structure of the roof, and whose compass pipes can be raised radially, also raising the enclosures and part of the belts and with the axle at its point of articulation, by virtue of the action exerted on them by rack-and-pinion bars, the upper end of which is articulated on the compass tube, and whose racks are subjected to the action of toothed pinions fixed and driven by a gearmotor, which, in turn can be operated mechanically or manually, in this case by driving a crank related to the gearmotor by transmission suitable, so that the toothed pinion drive on the rack raises it, changing its po position inclined until reaching the vertical, coinciding with the point of maximum opening of the window of the window, arranging at the end of the compass tube of the appropriate fastening which, when descending to the initial position, fits appropriately in appropriate fasteners located at the edge of the gutter on which is discussed, so as not to disturb the pouring of the water in that, when the compass tube is down, this is closing the window of ventilation that produces its opening.
