Description

Das von den beiden seitlichen Einzugsschnecken 2 liierangeführte Dreschgut wird von den Förderschnekken 4 erfaßt und durch den Einzugskanal 3 gefördert. Infolge der Verjüngung der Förderschnecken 4 und des Einzugskanals 3 wird das Dreschgut leicht verdichtet und durch die kleinere Auslaßöffaung des Einzugskanals hindurch dem Dreschwerk 5 zugeführt Die Förderschnecken 4 sindin der Lage, große Mengen Erntegut einwandfrei zu befördern. Die Ί,ει-stune der Maschine wird dadurch erhöht Audi ist die Staubentwicklung der erfindungsgemäßen Zuführvorrichtung geringer als bei den herkömmlichen, als Kettenförderer ausgebildeten Zufübrvornchtungen. The threshed material brought in by the two lateral intake augers 2 is taken from the augers 4 detected and conveyed through the intake channel 3. As a result of the tapering of the screw conveyors 4 and of the intake channel 3, the threshed material is slightly compressed and through the smaller Auslaßöffaung the Feed channel through the threshing mechanism 5. The screw conveyors 4 are able to handle large To transport quantities of crop properly. The Ί, ει-stune the machine is thereby increased Audi is the dust generation of the feeding device according to the invention is lower than with the conventional ones, supply devices designed as chain conveyors.
