Abstract

The front of the cutting table (3) has a line of air jets (1) directed upwards to lift any bent over ears into the gathering wheel and thereby to the cutters. The air is supplied by a blower at the rear of the cutting table and is ducted through a central duct. The air jets are directed upwards and can be swivelled about 180 deg. for special effects. The air effect is applied over the entire width of the cutting table and lifts and lowers with the table adjustment. USE/ADVANTAGE - The airjet alignment allows the operator to set the cutters for min. straw intake and max. grain yield, even with bent-over ears.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Lage­ verändern des Bergegutes vor Schneid- und Bergeeinricht­ ungen.The invention relates to a device for location change the salvage before cutting and salvage equipment inungen.

Beispielsweise sind zum Anheben von Ähren vor einem Schneid­ vorgang mechanische Ährenheber bekannt. Diese bekannten Vor­ richtungen benötigt man dazu, daß die abgeknickten Ähren­ tragenden Halme auf einer schiefen Ebene von unten nach oben geschoben werden und aufgesammelt werden können. Dies funktioniert, wenn der Ährenheber nahe über den Boden ge­ schoben werden kann und die Halme im unteren Bereich geknickt sind.For example, to raise ears before cutting operation mechanical crop lifters known. This well-known before directions are needed to ensure that the broken ears supporting straws on an inclined plane from the bottom to the bottom can be pushed up and picked up. This works when the crop lifter is close to the ground can be pushed and the stalks bent in the lower area are.

Sind die Halme im oberen Bereich geknickt fallen sie zwischen den Hebern durch und können nicht geerntet werden, außer man fährt das Schneid- oder Sammelwerk ganz unten nahe am Boden. If the stalks are kinked in the upper area, they fall between them through the lifters and cannot be harvested except one drives the cutting or collecting unit at the bottom near the ground.  

Diese Methode hat die Nachteile, daßThis method has the disadvantages that

  • 1. eine Vielzahl von Hebern auf die Arbeitsbreite ver­ teilt werden muß.1. a variety of jacks on the working width ver must be shared.
  • 2. die Schneidleistung der Messer abnimmt, da die zur Verfügung stehende Schnittfläche z. B. bei Fingermes­ serbalken durch die Vielzahl der Heber abnimmt.2. The cutting performance of the knives decreases, because the Available cutting surface z. B. at Finger Mes serbalken decreases due to the large number of jacks.
  • 3. die Heber nahe oder fast am Boden geführt werden müssen.3. The lifters must be brought close to or almost to the ground.
  • 4. daß es dadurch zu Steinklemmern kommt.4. that this leads to stone jamming.
  • 5. daß durch das am Boden Führen die Bergeleistung von Körnern eingeschränkt ist, da der ganze Halm z. B. beim Mähdrescher gedroschen werden muß.5. that the mountain performance of Grains is restricted because the whole stalk z. B. at Combine must be threshed.

Aufgabe der Erfindung ist diese Nachteile zu vermeiden, und zwar durch:The object of the invention is to avoid these disadvantages, by:

  • a) einen erzeugten gerichteten Luftstrom der die Lage der Ähren so verschiebt, daß Schnitthöhe beim Ähren­ sammeln in der Höhe angepaßt werden kann in der die Ähren sich befinden.a) A directed airflow generated the location the ears so that the cutting height when earing collecting can be adjusted in the amount at which Ears of corn.
  • b) keine mechanischen Teile den Schneidvorgang behindern.b) no mechanical parts hinder the cutting process.
  • c) keine Steinklemmer stattfinden.c) there are no stone clamps.
  • d) die Bergeleistung erhöht wird.d) the recovery is increased.

Nachstehend wird die Erfindung in der Zeichnung anhand von Ausführungsbeispielen erläutert. Es zeigt:The invention is illustrated below in the drawing explained by exemplary embodiments. It shows:
