<p>The object of the invention is to make available an arrangement for the transport of goods in bulk, such as cereal grain, by means of air flowing through a perforated base plate, in conjunction with which arrangements are provided in areas of the base plate (1) adjacent to the perforations (7) to impart to the air flowing through at that point a movement component running along the base plate (1), where a minimum quantity of air is required in order to transport the desired quantity of goods in bulk. In accordance with the invention the perforations (7) consist of elongated slots running across the direction of flow, that is to say the direction of feed, which slots are laterally displaced in relation to the slots in front of and behind them in an unsymmetrical manner, such that they form diagonal rows (B; C), the angles (α; β) of which to the direction of transport (A) are considerably smaller in one lateral direction than in the other, when measured from one of the slots.</p> |
