Abstract

The present invention describes a self-propelled forage harvester [1] with engine and radiator fan unit assigned to this, a rotating screen device [11] being assigned to the radiator. In order to prevent this rotating screen device [11] being clogged by impurities in the intake air, the impurities are constantly drawn off by a suction device, the flow of air needed for drawing off being produced by the post-accelerator [6] so that the particles of dirt are expelled with the chopped material. Consequently there is no longer any risk of impurities in the engine compartment [14]. <IMAGE>

Description

Die Neuerung betrifft eine selbstfahrende Erntemaschine mit einem Antriebsmotor, einem Kühler mit Kühlerventilator und einer letzterem zugeordneten Siebeinrichtung zum Zurückhalten von in der angesogenen Kühlluft vorhandenen Schmutzpartikel, wobei der rotierenden Siebeinrichtung im Bereich der Luftansaugseite ein zur Siebeinrichtung zumindest teilweise offenes Sauggehäuse zugeordenet ist, dessen wirksame Saugfläche kleiner ist als die Lufteinlaßfläche der rotierenden Siebeinrichtung.The innovation relates to a self-propelled harvesting machine with a drive motor, a cooler with cooler fan and a sieve device assigned to the latter for retaining dirt particles present in the sucked-in cooling air, the rotating sieve device in the area of the air intake side being assigned a suction housing which is at least partially open to the sieve device and whose effective suction surface is smaller than the air inlet area of the rotating screen device.

Aus der Praxis ist ein selbstfahrender Mähdrescher bekannt, der eine rotierende Siebeinrichtung aufweist, die dem Motorkühler und dem Ventilator des Antriebsmotors vorgeordnet ist. Der Zweck einer derartigen rotierenden Siebeinrichtung liegt darin, Schutzpartikel aus der vom Motorventilator angesaugten Luft zurückzuhalten, damit der zwischen Siebeinrichtung und Ventilator angeordnete Wasserkühler nicht mit Staub und Schmutz zusetzt. Um nun aber zu erreichen, daß sich die rotierende Siebeinrichtung selbst nicht mit Staub und Schmutz zusetzt, ist ein Umgehungskanal vorgesehen, der den Kühler umgeht und mit seinem einen offenen Ende direkt vor der Ansaugseite des Ventilators endet und in ein Sauggehäuse mündet, welches auf der Luftzufuhrseite der rotierenden Siebeinrichtung nahe dieser angebaut ist und an seiner der Siebeinrichtung zugewandten Seite offen ist. Auf diese Weise wird erreicht, daß vom Motorventilator Luft über den Umgehungskanal durch das Gehäuse gesaugt wird und durch den Luftstrom die an der Ansaugseite der rotierenden Siebeinrichtung anhaftenden Staub- und Schmutzpartikel abgesaugt werden. Die rotierende Siebeinrichtung bleibt infolgedessen sauber , so daß stets genügend saubere Luft zur Kühlung des Wasserkühlers vom Motorventilator angesogen werden kann. Der Nachteil, so zu verfahren, liegt allerdings darin, daß der durch das Reinigungsgehäuse von der Außenseite der rotierenden Siebeinrichtung abgezogene mit Verunreinigungen durchsetzte Luftstrom direkt in den Motorraum geblasen wird und diesen verschmutzt. Der Schmutz primär ist hier nicht der ausschlaggebende Faktor, sondern vielmehr die durch den von der Motorwärme getrockneten Staub hervorgerufene Brandgefahr. Es wurde auch schon vorgeschlagen, die angesogene verschmutzte Luft über Luftführungskanäle im Motorraum am Motor vorbeizuführen. Dieser Versuch brachte aber nicht den gewünschten Erfolg, da die Kanäle wegen Mangel an Einbauraum nur relativ klein im Durchmesser gehalten werden konnten, so daß keine ausreichende Abfuhr der verschmutzten Luft gewährleistet war.A self-propelled combine harvester is known from practice, which has a rotating sieve device which is arranged upstream of the engine cooler and the fan of the drive engine. The purpose of such a rotating sieve device is to retain protective particles from the air drawn in by the motor fan, so that the water cooler arranged between the sieve device and the fan does not become clogged with dust and dirt. In order to ensure that the rotating sieve device does not clog itself with dust and dirt, a bypass channel is provided which bypasses the cooler and ends with its one open end directly in front of the suction side of the fan and opens into a suction housing, which on the Air supply side of the rotating sieve device is mounted close to it and is open on its side facing the sieve device. In this way it is achieved that air is sucked through the bypass duct through the housing by the motor fan and the dust and dirt particles adhering to the suction side of the rotating sieve device are sucked off by the air flow. As a result, the rotating sieve device remains clean, so that enough clean air can always be drawn in by the motor fan to cool the water cooler. The disadvantage of doing this, however, is that the air flow drawn through the cleaning housing from the outside of the rotating sieve device and contaminated with it is blown directly into the engine compartment and contaminates it. Primarily, the dirt is not the decisive factor here, but rather the risk of fire caused by the dust dried by the engine heat. It has also already been proposed that the sucked-in polluted air be led past the engine via air guiding channels in the engine compartment. However, this attempt did not bring the desired success, since the ducts could only be kept relatively small in diameter due to the lack of installation space, so that adequate removal of the polluted air was not ensured.

Der Neuerung liegt, ausgehend von einer Erntemaschine der eingangs näher bezeichneten Art das Problem zugrunde, die sich an der Ansaugseite einer rotierenden Siebeinrichtung absetzenden Schmutzpartikel abzusaugen und so abzuleiten, daß weder Verunreinigungen der Erntemaschine noch Brandgefahr durch sich festsetzende Verunreinigungen entstehen, ohne komplizierte und teure Luftleitsysteme im inneren des Motorraumes wegen des geringen vorhandenen Einbauraums hierfür vorsehen zu müssen. Das wird neuerungsgemäß dadurch erreicht, daß das Sauggehäuse über eine äußere Rohrleitung mit der Saugseite eines das Erntegut beaufschlagenden Gebläses verbunden ist. Dieses Gebläse kann beispielsweise das der Siebeinrichtung eines Mähdreschers zugeordnete Druckwindgebläse sein. Da der Staubanfall im Bereich eines solchen Gebläses ohnehin sehr groß ist, fallen die vom Gehäuse mitgeförderten Staubpartikel aus dem Bereich der dem Motorkühler vorgeordneten rotierenden Siebeinrichtung ohnehin kaum ins Gewicht.The innovation is based, starting from a harvester of the type specified in the introduction, on the problem of suctioning off and removing the dirt particles settling on the suction side of a rotating sieve device in such a way that neither contaminations of the harvester nor a risk of fire due to contaminants which form themselves occur, without complicated and expensive air guidance systems to have to be provided in the interior of the engine compartment because of the small available installation space. According to the innovation, this is achieved in that the suction housing is connected via an outer pipe to the suction side of a blower acting on the crop. This blower can be, for example, the pressure wind blower assigned to the screening device of a combine harvester. Since the amount of dust in the area of such a fan is very high anyway, the dust particles conveyed by the housing from the area of the rotating sieve device upstream of the engine cooler are of little importance anyway.

Ein wesentliches Merkmal der Neuerung ist allerdings darin zu sehen, daß die Erntemaschine ein an sich bekannter Häcksler mit in seinem Auswurfschacht angeordneten Nachbeschleuniger ist, wobei das der rotierenden Siebeinrichtung zugeordnete Sauggehäuse über eine Leitung mit der Saugseite des Nachbeschleunigers verbunden ist, wobei beispielsweise die rotierende Siebeinrichtung zwischen dem Motorraum und der Leitung angeordnet ist. In diesem Fall gestaltet sich zum einen die Verbindung vom Nachbeschleuniger zur rotierenden Siebeinrichtung sehr einfach und zum anderen gelangt der Luftstrom direkt über das Ausfallrohr ins Freie, ohne irgendwelche Maschinenteile mit Staub zu belasten.An essential feature of the innovation is, however, that the harvesting machine is a chopper known per se with a post-accelerator arranged in its discharge chute, the suction housing assigned to the rotating sieve device being connected via a line to the suction side of the post-accelerator, for example the rotating sieve device is arranged between the engine compartment and the line. In this case, on the one hand, the connection from the post-accelerator to the rotating screening device is very simple and, on the other hand, the air flow is released directly through the outlet pipe without polluting any machine parts with dust.

Im folgenden soll die Erfindung anhand eines Ausführungsbeispiels und zweier dieses schematisch darstellender Figuren näher erläutert werden.In the following, the invention will be explained in more detail with the aid of an exemplary embodiment and two figures which represent this schematically.

Dabei zeigt:

  • Fig. 1 einen selbstfahrenden Feldhäcksler in der Seitenansicht ohne Seitenverkleidung und
  • Fig. 2 Einzelheiten des in Fig. 1 dargestellten Feldhäckslers in vergrößerter Darstellung.
It shows:
  • Fig. 1 shows a self-propelled forage harvester in side view without side panels and
  • Fig. 2 details of the forage harvester shown in Fig. 1 in an enlarged view.

Mit 1 ist ein selbstfahrender Feldhäcksler bezeichnet, der in an sich bekannter Weise vordere Guteinzugsorgane 2 aufweist, denen das eigentliche Häckselaggregat 3 nachgeschaltet ist. Das von diesem Häckselaggregat 3 zerkleinerte Gut gelangt zu einem Konditionierwalzenpaar 4, durch welches das Häckselgut zerquetscht wird. Um nun dieses zerquetschte Häckselgut einwandfrei durch den gekrümmten Auswurfkanal 5 beispielsweise auf ein paralell neben dem Feldhäcksler herfahrendes Transportfahrzeug abwerfen zu können, ist in Förderrichtung betrachtet hinter dem Konditionierwalzenpaar 4 ein Nachbeschleuniger 6 vorgesehen. Er besteht im wesentlichen aus einer antreibbaren Achse 7 und ihr zugeordneten Förderleisten 8, wobei die Förderleisten 8 einen Abstand zur Achse 7 aufweisen. Die Förderleisten wirken mechanisch auf das ihnen durch das Konditionierwalzenpaar zugeführte Erntegut ein und schleudern letzteres durch den Auswurfkanal 5 mit genügender Energie nach außen. Der Nachbeschleuniger 6 ist als Teil des Auswurfkanals 5 ausgebildet. An die Saugseite dieses Nachbeschleunigers ist eine Leitung 9 angeschlossen, die mit ihrem anderen Ende an ein GEhäuse 10 angeschlossen ist. Letzteres ist einer rotierenden Siebeinrichtung 11 zugeordnet und bedeckt sowohl einen Teil ihrer Stirnfläche 12 wie auch einen Teil ihres Mantels 13, wobei das Gehäuse an seiner der rotierenden Siebeinrichtung 11 zugewandten Seite ganz offen ist oder zumindest Öffnungen aufweist, so daß Staub und Verunreinigungen über die Leitung 9 abgesaugt werden können. Auf diese Weise ist gewährleistet, daß sich einerseits die rotierende Siebeinrichtung nicht zusetzen kann und andererseits der Motorraum 14 nicht verschmutzt, da die abgesaugten Teilchen mit dem Häckselgut über den Auswurfkanal den Maschinenraum verlassen.1 with a self-propelled forage harvester is referred to, which in a known manner has front material intake elements 2, which are followed by the actual chopping unit 3. The material comminuted by this chopping unit 3 arrives at a pair of conditioning rollers 4 through which the chopped material is crushed. In order to be able to drop this crushed chopped product properly through the curved discharge channel 5, for example onto a transport vehicle traveling parallel to the forage harvester, a post-accelerator 6 is provided behind the pair of conditioning rollers 4, viewed in the conveying direction. It essentially consists of a drivable Axis 7 and its associated conveyor strips 8, the conveyor strips 8 being at a distance from the axis 7. The conveyor strips act mechanically on the crops fed to them by the conditioning roller pair and fling the latter out through the ejection channel 5 with sufficient energy. The post-accelerator 6 is designed as part of the ejection channel 5. A line 9 is connected to the suction side of this post-accelerator, and its other end is connected to a housing 10. The latter is assigned to a rotating sieve device 11 and covers both a part of its end face 12 and a part of its jacket 13, the housing on its side facing the rotating sieve device 11 being completely open or at least having openings so that dust and contaminants pass through the line 9 can be suctioned off. This ensures that, on the one hand, the rotating sieve device cannot become clogged and, on the other hand, the engine compartment 14 does not become dirty, since the extracted particles with the chopped material leave the machine compartment via the ejection channel.
