Improvements to silo discharge devices of the type comprising a floor held above the bottom thereof and having hollow ribs forming under the floor ventilation passageways separated by plane portions, wherein air penetrates in buckets delimited by the floor and two adjacent ribs (4), through transversal slots (8) provided at the bottom of said buckets. A plate (9) is arranged above each slot (8) and extends partially above the underlying plate arranged downstream forming between the two plates a slot (10), the covering length being bigger than that of the fall slope of the product in question at right angles with the slot. |
