<p>1. Device for gripping, transferring an distributing very small elements one by one, namely sowing seeds, comprising a hollow, mobile gripping part (7) having at least one hole (9) smaller insize than the elements to be grasped, a source of pressure connected to the said part, a container (3) containing in bulk a multitude of elements to be grasped, and means for bringing the said gripping part from a position of gripping the elements to a position of distributing the elements, and inversely, vibration means being provided for detaching from each hole (9) the gripping part (7) all the elements except that which, occupying a central position in relation to the hole, undergoes the greatest retaining effect, characterized by the fact the said gripping part (7) is integral wiht the container (3), that the container is mounted so that it can pivot around a horizontal axis (13a), that the said means of transfer from the position of gripping the elements to the position of distributing the elements act on the said container to make the latter pivotaround the said horizontal axis (13a) between the gripping position in which the container is inclined in such a way that the elements in bulk are located in contact with the gripping part and one other inclined position of the container which is the position of distribution in which the said elements in bulk are withdrawn from the gripping part, each hole (9) of which, due of an opening (11) of the container, is located in this position of distribution facing a discharge opening (26) of a fixed reception part (2) and that the vibration means are constituted by a vibrator (14-23) which acts on the said container (3) for detaching by inertia the elements in excess from each hole.</p> |
