Abstract

The shakerless self-propelled combine harvester with drum and concave has a series of parallel separator drums one after the other in the transport direction, each with a perforated sheet-metal trough underneath having friction bars parallel to the drum axis. The holes (6) in the troughs can be partly masked, and the troughs themselves have raised ribs parallel to each other in the direction of material flow. Masking can be by slides (10) underneath the troughs, and with perforations which can be brought into line with those in the latter.

Description

Schüttlerloser selbstfahrender MähdrescherShakerless self-propelled combine harvester

Die Erfindung betrifft einen schüttlerlosen selbstfahrenden Mähdrescher mit Dreschtrommel, Dreschkorb und mehreren in Transportrichtung dahinter parallel zueinander angeordneten Abscheidetrommeln, denen jeweils ein unterhalb derselben vorgesehenes Abscheideelement in Form von gelochten wannenförmig gebogenen Blechen mit parallel zur Trommellängsachse verlaufenden Reibleisten zugeordnet ist, welche auf Tragleisten aufliegen, die sich in Längsrichtung des Mähdreschers erstrecken.The invention relates to a self-propelled combine harvester without a shaker with threshing drum, concave and several parallel behind in the direction of transport separating drums arranged to one another, each of which has one below the same provided separating element in the form of perforated, trough-shaped bent sheets is associated with running parallel to the drum longitudinal axis friction strips, which rest on support strips that extend in the longitudinal direction of the combine harvester.

Bei Mähdreschern der obengenannten Art müssen, um eine zufriedenstellende Restkornausscheidung und um möglichst wenig Kornbruch zu erreichen, die Abscheideelemente stets den zu erntenden Gutarten und den vorhandenen Klimabedingungen angepaßt werden und zwar jeweils durch Austausch entsprechender Elemente gegeneinander. So zu verfahren bedeutet aber zunächst einmal die Lagerhaltung einer Vielzahl unterschiedlich ausgebildeter Abscheideelemente. Ein weiterer Nachteil ist in dem großen Arbeits- und Zeitaufwand für den Austausch einzelner Elemente gegen andere zu sehen. Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Mähdrescher der eingangs näher bezeichneten Art zu schaffen, der einen Austausch der Abscheideelemente zwecks Anpassung an verschiedene Erntebedingungen und zwecks Vermeidung von Kornbruch überflüssig macht. Das wird erfindungsgemäß dadurch erreicht, daß die Löcher der wannenförmig gebogenen Bleche zumindest bereichsweise abdeckbar und die Bleche selbst mit in Gutflußrichtung parallel nebeneinander verlaufenden erhebenen Stegen versehen sind. Nach einem weiteren Merkmal der Erfindung sind unterhalb der Bleche mit Durchgangslöcher versehene Schieber angeordnet, wobei die Durchgangslöcher denen der Bleche entsprechen. Auf konstruktiv einfache Art und Weise sind die Schieber auf Führungswinkel gelagert und mittels Gewindemutter und Spindel verschiebbar. Um eine möglichst optimale Anpassung an die jeweiligen Gutarten zu gewährleisten, sind die Reibleisten auswechselbar mit den Blechen verbunden. Es hat sich dabei als zweckmäßig erwiesen, daß die Stege und die Reibleisten gleiche Höhe aufweisen.In combine harvesters of the type mentioned above must be a satisfactory Residual grain separation and, in order to achieve as little grain breakage as possible, the separation elements are always adapted to the types of crops to be harvested and the existing climatic conditions in each case by exchanging the corresponding elements for each other. To do so but first of all means the storage of a large number of differently trained Separation elements. Another disadvantage is the great amount of work and time required for exchanging individual items for others to see. The present invention is therefore based on the object of a combine harvester of the type specified in the introduction Art to create an exchange of the separation elements for the purpose of adapting to different Makes harvesting conditions and in order to avoid grain breakage superfluous. That will according to the invention achieved in that the holes of the trough-shaped bent sheets Can be covered at least in some areas and the sheets themselves are parallel in the direction of crop flow Raised webs running side by side are provided. According to another feature of the invention are slides provided with through-holes below the metal sheets arranged, the through holes corresponding to those of the sheets. On constructive simple way, the slides are mounted on guide brackets and by means of Threaded nut and spindle can be moved. In order to achieve the best possible adaptation to To ensure the respective types of goods, the friction strips are interchangeable with connected to the sheets. It has proven to be useful that the webs and the friction strips have the same height.

Im folgenden soll die Erfindung anhand eines Ausführungsbeispieles und mehrerer dieses schematisch darstellender Figuren näher erläutert werden. Dabei zeigt: Fig. 1 einen schüttlerlosen Mähdrescher in der Seitenansicht, Fig. 2 in der Draufsicht einen Teil des Abscheideelements im Bereich der Korbverstellspindel, Fig. 3 einen Schnitt gemäß der Linie III-III der Fig. 2, Fig. 4 einen Schnitt gemäß der Linie IV-IV der Fig. 2-, Fig. 5 eine Draufsicht wie Fig. 2 jedoch mit zusätzlichen Stegen im Abscheideelement, Fig. 6 einen Schnitt nach der Linie VI-VI der Fig. 5, Fig. 7 einen Schnitt nach der Linie VII-VII der Fig. 5.-Mit 1 sind die Seitenwände eines Mähdreschers bezeichnet, in denen sowohl die Dreschtrommel 2 mit dem zugehörigen Dreschkorb 3 wie auch in Förderrichtung hinter dem Dreschkorb 3 sechs Abscheidetrommeln 4 gelagert sind. Unterhalb einer jeden Abscheidetrommel 4 sind wannenförmig gebogene Abscheideelemente 5 angeordnet, die aus in ihrem Abscheidebereich mit Langlöchern 6 versehenen Blechen bestehen, auf die parallel zu den Achsen der Abscheidetrommeln 4 verlaufende Reibleisten 7 aufgeschraubt sind.In the following, the invention will be based on an exemplary embodiment and several of this schematically depicting figures are explained in more detail. Included shows: FIG. 1 a shaker-less combine harvester in side view, FIG. 2 in FIG Top view of part of the separation element in the area of the basket adjustment spindle, 3 shows a section along the line III-III in FIG. 2, FIG. 4 shows a section according to the line IV-IV of FIG. 2-, FIG. 5 is a plan view like FIG. 2, but with additional Web in the separation element, Fig. 6 is a section along the line VI-VI of Fig. 5, Fig. 7 shows a section along the line VII-VII of Fig. 5.-With 1 are the side walls a combine, in which both the threshing drum 2 with the associated Concave 3 as well as six separating drums behind the concave 3 in the conveying direction 4 are stored. Below each separation drum 4 are curved tub-shaped Separation elements 5 arranged, which are made in their separation area with elongated holes 6 provided sheets exist, on the parallel to the axes of the separation drums 4 running friction strips 7 are screwed on.

Bei Abscheideelementen mit Blechboden.und aufgeschraubten Reibleisten kann durch die unmittelbare Reibwirkung zwischen dem Gut und dem gelochten Blechboden starke Strohzerstörung und Körnerbruch hervorgerufen werden. Um dies zu verhindern, weisen, wie die Figuren 5 bis 7 zeigen, die Abscheideelemente 5 neben den Reibleisten 7 noch erhabene Stege 8 auf, die sich parallel mit Abstand zueinander in Gutdurchflußrichtung erstrecken und genau so hoch sind, wie die Reibleisten 7, wie dies auch die Figuren 6 und 7 veranschaulichen. Durch eine solche Ausbildung der Bleche mit in Flußrichtung durchgehenden nebeneinanderliegenden Stegen ist für Langstroh kein direkter Kontakt zum gelochten Blechboden gegeben, woraus eine geringere Strohzerstörung, eine bessere Kornabscheidung und geringerer Körnerbruch resultiert. Um nun bei unterschiedlichen Fruchtarten und bei wechselnden Klimaverhältnissen die Lochbleche nicht ständig gegen solche mit größeren oder kleineren Lochungen austauschen zu müssen, wie dies bisher erforderlich war, sind unterhalb der mit Löchern 6 versehenen Bleche Führungswinkel 9 mit den Abscheideelementen 5 fest verbunden, auf denen Schieber 10 gelagert sind, die über mindestens eine an jedem Schieber 10 befestigte Spindelmutter 11 und über eine Spindel 12 auf den Winkel 9 verschoben werden können, so daß je nach Verstellgrad die in dem Schieber sich befindlichen Löcher 13 mit den Löchern 6 der Abscheideelemente 5 fluchten oder letztere 6 teilweise oder ganz vom Schieber 10 abgedeckt werden. Die Spindel 12 ist dabei in mit den Abscheideelementen 5 verschweißten Konsolen 14 gelagert und mittels eines durch eine Öffnung in der Drescherseitenwand zuführbaren Steckschlüssel 15 verdrehbar.For separating elements with a sheet metal base and screwed-on friction strips can through the direct friction between the goods and the perforated sheet metal base severe straw destruction and grain breakage are caused. To prevent this, have, as FIGS. 5 to 7 show, the separating elements 5 next to the friction strips 7 still raised webs 8, which are parallel at a distance from one another in the flow direction of the crop extend and are just as high as the friction strips 7, like the figures Figures 6 and 7 illustrate. Such a design of the sheets with in the direction of flow continuous adjacent Stegs are not for long straw direct contact with the perforated sheet metal floor, resulting in less straw destruction, better grain separation and less grain breakage result. To now with different Fruits and in changing climatic conditions the perforated sheets not constantly to have to swap for ones with larger or smaller holes, like this was previously required, guide angles are provided below the plates with holes 6 9 firmly connected to the separation elements 5, on which slides 10 are mounted, the at least one spindle nut 11 attached to each slide 10 and above a spindle 12 can be moved to the angle 9, so that depending on the degree of adjustment the holes 13 in the slide with the holes 6 of the separation elements 5 are aligned or the latter 6 are partially or completely covered by the slide 10. The spindle 12 is in brackets welded to the separation elements 5 14 stored and can be fed by means of a through an opening in the thresher side wall Socket wrench 15 rotatable.
