Description

Gegenstand der Erfindung ist eine Dreschmaschine, bei der die durch den Dreschkorb fallenden und die hinter dem Dreschkorb anfallenden Körner getrennt vorgereinigt und einer gemeinsamen Reinigungsvorrichtung zugeführt werden.The invention relates to a threshing machine in which the threshing concave Grains that fall and those that fall behind the concave are pre-cleaned and separately be fed to a common cleaning device.

Gemäß der Erfindung ist zu diesem ZweckAccording to the invention is for this purpose

ein von einem aufsteigenden Luftstrom durchströmter schräger Kanal vorgesehen, in welchen oben eine Förderschnecke für das durch den Dreschkorb fallende Gut mündet und an den sich unten das Aufnahmeende eines parallel zu ihm liegenden Becherwerks anschließt, in welches eine Förderschneckean inclined channel through which an ascending stream of air flows is provided, in which opens up a screw conveyor for the crop falling through the concave and at the bottom the receiving end of a bucket elevator lying parallel to it connects, in which a screw conveyor

»5 für das hinter dem Dreschkorb anfallende Gut mündet.»5 for that which arises behind the concave Ends well.

Die Zeichnung veranschaulicht den Erfindungsgegenstand in einer beispielsweisen Ausführungsform. The drawing illustrates the subject matter of the invention in an exemplary embodiment.

Die Schnecke ο preßt das durch den Dreschkorb ausgetretene Gemenge von Körnern, Kaff, Ähren usw. in den den Kanal b von unten nach oben durchströmenden Windstrom, ohne dem Wind den Austritt zu gestatten. Die leichten Teile (Kaff, Ähren usw.) werden durch das Rohr e fortgeblasen, während die schwereren Teile nach unten fallen und infolge der düsenartigen Wirkung der Verengerung des Kanals bei g einem verstärkten Luftstrom ausgesetzt werden, so daß nur die schweren Körner abwärts bis zum Auslauf des Kanals / gelangen, während alle leichteren Teile aufwärts geblasen werden.The auger ο presses the mixture of grains, chaff, ears of corn, etc. that has escaped through the concave into the wind stream flowing through the channel b from bottom to top without allowing the wind to exit. The light parts (chaff, ears of corn, etc.) are blown away through the tube e , while the heavier parts fall down and, due to the nozzle-like effect of the narrowing of the channel at g , are subjected to an increased air flow, so that only the heavy grains down to Run out of the canal / while all lighter parts are blown upwards.

Die in Richtung auf die Schnecke zu geringere Geschwindigkeit des Luftstromes verhindert, daß die Körner, die in der düsenartigen Verengerung g vom Windstrom erfaßt und hochgeworfen werden, verlorengehen. Die Körner fallen in das Aufnahmeende des parallel zum Windkanal b liegenden Becherwerks 0, in das außerdem eine Förderschnecke m für das hinter dem Dreschkorb anfallende Gut mündet.The speed of the air flow, which is too slow in the direction of the screw, prevents the grains, which are caught in the nozzle-like constriction g and thrown up by the wind flow, from being lost. The grains fall into the receiving end of the bucket elevator 0, which is parallel to the wind tunnel b and into which a screw conveyor m for the material behind the concave also opens.

Patentanspruch:Claim: Dreschmaschine, bei der die durch den Dreschkorb fallenden und die hinter dem Dreschkorb anfallenden Körner getrennt vorgereinigt und einer gemeinsamen Reinigungsvorrichtung zugeführt werden, gekennzeichnet durch einen von einem aufsteigenden Luftstrom . durchströmten schrägen Kanal (b), in welchen oben eine Förderschnecke (α) für das durch den Dreschkorb fallende Gut mündet und an den sich unten das Aufnahmeende eines parallel zu ihm liegenden Becherwerks (o) anschließt, in welches eine Förderschnecke für das hinter dem Dreschkorb anfallende Gut mündet.Threshing machine in which the grain falling through the concave and the grain falling behind the concave are pre-cleaned separately and fed to a common cleaning device, characterized by an ascending air flow. The inclined channel (b) flowed through, into which a screw conveyor (α) for the material falling through the concave opens and to which the receiving end of a bucket elevator located parallel to it (o) connects, into which a screw conveyor for the one behind the concave accruing good flows.
