<p>The mechanism is for closing or opening a number of silos arranged in a row, each silo having a closing member including a rectangular frame (2) in which a number of parallel, relatively spaced, horizontal strips (4) secured to a bar (5), a grating being formed by components (2,3) and a closing slide being formed by components (4,5). The openings of the grating may be closed by displacing the strips (4) relative to the strips (3) with the aid of the bar (5). The closing slides can be reciprocated by the mechanism comprising a rectangular frame (6) having transverse beams (7,8) on each side of the closing member. The mechanism is provided with a stop (13) which is displaceable into the path of bar (5).</p> |
