Abstract
Description
Die Erfindung betrifft eine nach dem Axialflussprinzip arbeitende Dresch- und Trenneinrichtung für einen Mähdrescher, mit einem Dreschrotor und einem stromab des Dreschrotors angeordneten Trennrotor, der unabhängig vom Dreschrotor gelagert ist.The invention relates to a working according to the Axialflussprinzip threshing and separating device for a combine harvester, with a threshing rotor and a downstream of the threshing rotor arranged separation rotor, which is mounted independently of the threshing rotor.
Stand der TechnikState of the art
Mähdrescher wenden in der Landwirtschaft verwendet, um stängelartige Pflanzen von einem Feld zu ernten und Fruchtstände (z. B. Korn) von den Erntegutresten zu trennen. Dabei werden die Pflanzen durch eine Dresch- und Trenneinrichtung geführt und in einer Reinigungseinrichtung werden unerwünschte Erntegutreste (Spreu, Kurzstroh) von den Fruchtständen der Pflanzen separiert, welche schließlich in einem Korntank zwischengespeichert werden, bevor sie auf ein Transportfahrzeug überladen werden.Combine harvesters used in agriculture to harvest stalk-like plants from a field and to separate fruit stalls (eg, grain) from the crop residue. The plants are passed through a threshing and separating device and in a cleaning device unwanted crop residues (chaff, short straw) are separated from the crops of the plants, which are finally cached in a grain tank before they are overloaded on a transport vehicle.
Gegenüber konventionellen Tangentialdrescheinrichtungen mit nachfolgenden Strohschüttlern oder Trennrotoren hat die Bedeutung axialer Dresch- und Trenneinrichtungen in der Vergangenheit immer mehr zugenommen. Die axialen Dresch- und Trenneinrichtungen umfassen einen üblicherweise einstückig als Schweißzusammenbau ausgeführten Dresch- und Trennrotor, der innerhalb eines zugehörigen Gehäuses rotiert und einen in einem Dreschbereich mit Dreschelementen besetzten und in einem Trennbereich mit Trennelementen besetzten Rotormantel. umfasst. Der Dreschbereich und der Trennbereich rotieren mit gleicher Drehzahl, was nicht immer optimal ist, da die Drehzahl für den Dreschbereich an die Ernteguteigenschaften anzupassen ist, um eine möglichst gute Druschwirkung zu erzeugen. Dabei ist in vielen Fällen die Drehzahl für den Trennbereich zu groß, was einen unnötig hohen Antriebsleistungsbedarf bedingt, oder zu klein, sodass keine optimale Abscheidung der Restkörner aus der Erntegutmatte mehr stattfindet.Compared to conventional Tangentialdrescheinrichtungen with subsequent straw walkers or separation rotors, the importance of axial threshing and separating devices in the past has increased more and more. The axial threshing and separating means comprise a threshing and separating rotor, usually made in one piece as a welded assembly, which rotates within an associated casing and a rotor casing occupied by threshing elements in a threshing region and fitted with separating elements in a separating region. includes. The threshing area and the separating area rotate at the same speed, which is not always optimal, since the speed for the threshing area has to be adapted to the crop properties in order to produce the best possible threshing action. In many cases, the speed for the separation area is too large, which causes an unnecessarily high drive power requirement, or too small, so that no optimal separation of the residual grains from the Erntegutmatte takes place.

Problemproblem
Die der Erfindung zu Grunde liegende Aufgabe wird darin gesehen, eine im Axialfluss arbeitende Dresch- und Trenneinrichtung für einen Mähdrescher bereitzustellen, die eine einfache Anpassungsmöglichkeit der Drehzahl des Trennrotors an die jeweiligen Ernteguteigenschaften ermöglicht.The object underlying the invention is seen to provide an operating in the axial flow threshing and separating device for a combine harvester, which allows easy adjustment of the speed of the separator rotor to the respective crop characteristics.
Lösungsolution
Diese Aufgabe wird erfindungsgemäß durch die Lehre des Anspruchs 1 gelöst, wobei in den weiteren Patentansprüchen Merkmale aufgeführt sind, die die Lösung in vorteilhafter Weise weiterentwickeln.This object is achieved by the teaching of claim 1, which are listed in the other claims features that further develop the solution in an advantageous manner.
Eine nach dem Axialflussprinzip arbeitende Dresch- und Trenneinrichtung für einen Mähdrescher umfasst einen Dreschrotor und einen stromab des Dreschrotors angeordneten Trennrotor, der unabhängig vom Dreschrotor gelagert ist und mit einem mit verstellbarer Drehzahl antreibbaren Elektromotor in Antriebsverbindung steht.A threshing and separating device for a combine harvester operating according to the axial flow principle comprises a threshing rotor and a separating rotor arranged downstream of the threshing rotor, which is mounted independently of the threshing rotor and is drive-connected to an electric motor which can be driven with an adjustable rotational speed.
Auf diese Weise kann die Drehzahl des Trennrotors optimal an die Erntegutbedingungen angepasst werden und der Trennrotor kann ggf. mit kleinerer Drehzahl als der Dreschrotor rotieren, was zu einer Verminderung der Strohzerstörung gegenüber konventionellen Trennrotoren führt, die mit derselben Geschwindigkeit wie der Dreschrotor rotieren. Dadurch wird auch der Antriebsleistungsbedarf vermindert und eine Überlastung der Reinigung mit Strohbruchstücken vermieden. Der elektromotorische Antrieb ermöglicht auf einfache Weise eine Verstellung der Drehzahl des Trennrotors und erlaubt auch ein Reversieren im Fall einer Verstopfung. Die Drehzahl des Trennrotors kann manuell oder selbsttätig durch eine Steuerung verstellt werden, die beispielsweise auf einer Erfassung des aktuellen Durchsatzes oder der Durchlaufzeit des Ernteguts durch die Trenneinrichtung beruht und die Drehzahl bei größeren Durchsätzen bzw. längeren Durchlaufzeiten anhebt und bei kleineren Durchsätzen bzw. kleineren Durchlaufzeiten absenkt. Auch besteht die Möglichkeit, den Trennrotor mit einer zur Drehzahl des Dreschrotors proportionalen oder anderweitig davon abhängigen Geschwindigkeit anzutreiben.In this way, the speed of the separation rotor can be optimally adapted to the crop conditions and the separation rotor may optionally rotate at a lower speed than the threshing rotor, resulting in a reduction of straw destruction over conventional separation rotors which rotate at the same speed as the threshing rotor. This also reduces the power requirement and avoids overloading with straw fragments. The electromotive drive allows a simple way to adjust the speed of the separator rotor and also allows reversing in the event of a blockage. The speed of the separation rotor can be manually or automatically adjusted by a control, which is based for example on a detection of the current throughput or throughput time of the crop by the separator and raises the speed for larger throughputs or longer processing times and smaller throughputs or smaller throughput times lowers. It is also possible to drive the separation rotor with a speed proportional to the threshing rotor or otherwise dependent thereon speed.
Vorzugsweise steht auch der Dreschrotor mit einem mit verstellbarer Drehzahl antreibbaren Elektromotor in Antriebsverbindung.Preferably, the threshing rotor is also drivingly connected to an electric motor which can be driven with an adjustable speed.
