Abstract

In these cutting machines, the conveying trough (1) is passed through beneath the swivelling gear (2) of the cutting arm. The conveying trough (1) serves to convey the cut material from the loading table of the cutting machine to the rear and to discharge it onto a conveyor. The front end (6) and the rear end (10) of the conveying trough (1) have a fixed part (4) extending below the swivelling gear, and a front part (6) of a conveying trough is pivotably linked to the front and the rear part (10) of the same to the rear of this fixed part (4). Consequently, when the front and rear part are pivoted, the cross-section of passage for the cut material below the swivelling gear is retained unchanged. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Anordnung der Förderrinne bei Teilschnittschrämmaschinen, bei welchen die Förderrinne unter dem Schwenkwerk des Schrämarmes hindurchgeführt ist, das vordere Ende der Förderrinne im Bereich des Ladetisches heb-und senkbar angelenkt ist und das hintere Ende derselben höhenverstellbar ist, wobei die Förderrinne aneinander angelenkte Teile aufweist. In der Förderrinne wird das gescHrämte Material von der Laderampe nach hinten gefördert und am hinteren Ende auf einen angeschlossenen Förderer abgeworfen. Je nach der Höheneinstellung der Laderampe verändert sich die Höhenlage des vorderen Endes der Förderrinne und je nach der Höhe des angeschlossenen Förderers muß das hintere Ende verstellt werden. Es ist bekannt, die Förderrinne einteilig auszubilden, wobei sich bei Höhenveränderung der beiden Enden der Förderrinne die Höhe der Förderrinne unterhalb des Schwenk- , werkes verändert. Bei höherer Einstellung der beiden Enden verringert sich somit der freie Durchgangsquerschnitt unter dem Schwenkwerk und es wird die Höhe des freien Durchgangsquerschnittes verringert. Wenn das hintere Ende, d.h. das Abwurfende der Förderrinne, höher eingestellt wird, so wird der freie Durchgangsquerschnitt im Bereich unterhalb des Schwenkwerkes von vorne nach hinten immer niedriger,, so daß die Gefahr besteht, daß sich größere Brocken in diesem Durchgangsquerschnitt verklemmen und die Förderrinne blockiert wird. Es wurde daher bereits vorgeschlagen, die Förderrinne zweiteilig auszubilden und die beiden Teile mittels einer horizontalen Anlenkachse, welche unterhalb des Schwenkwerkes liegt, aneinander anzulenken. Bei einer solchen Ausbildung verringert sich die Höhe des Eintrittsquerschnittes in dem Bereich unterhalb des Schwenkwerkes, wenn die Laderampe höhergestellt wird. Wenn das Abwurfende höhergestellt wird, verringert sich die Höhe des Austrittsquerschnittes aus dem Bereich unterhalb des Schwenkwerkes. Im ersteren Fall werden größere Brocken vor dem Eintritt in den Bereich unterhalb des Schwenkwerkes zurückgehalten und im letzteren Falle kann es auch wieder zu Verklemmungen in dem Durchgangsquerschnitt unterhalb des Bereiches des Schwenkwerkes kommen.The invention relates to an arrangement of the conveyor trough in partial cutting machines, in which the conveyor trough is passed under the swivel mechanism of the cutting arm, the front end of the conveyor trough is articulated in the region of the loading table and the rear end thereof is adjustable in height, the conveyor trough has hinged parts. In the conveyor trough, the cut material is conveyed backwards from the loading ramp and dropped onto a connected conveyor at the rear end. Depending on the height setting of the loading ramp, the height of the front end of the conveyor trough changes and depending on the height of the connected conveyor, the rear end must be adjusted. It is known to design the conveyor trough in one piece, the height of the conveyor trough changing below the swivel mechanism when the height of the two ends of the conveyor trough changes. With a higher setting of the two ends, the free passage cross-section under the swivel mechanism is reduced and the height of the free passage cross-section is reduced. If the rear end, i.e. the discharge end of the conveyor trough, is set higher, the free passage cross section in the area below the swivel mechanism from front to back becomes ever lower, so that there is a risk that larger chunks get jammed in this passage cross section and the conveyor trough is blocked. It has therefore already been proposed to design the conveyor trough in two parts and to articulate the two parts to one another by means of a horizontal articulation axis which lies below the swivel mechanism. With such a design, the height of the inlet cross section in the area below the swivel mechanism is reduced when the loading ramp is raised. If the discharge end is raised, the height of the outlet cross section from the area below the swivel mechanism is reduced. In the former case, larger chunks are returned before entering the area below the swivel mechanism hold and in the latter case jamming in the passage cross-section below the area of the swivel mechanism can also occur again.

Die Erfindung zielt nun darauf ab, Verklemmungen im Bereich unterhalb des Schwenkwerkes mit Sicherheit zu vermeiden und besteht daher im wesentlichen darin, daß die Förderrinne einen sich unterhalb des Schwenkwerkes erstreckenden ortsfesten Bereich aufweist, an welchen der vordere Teil der Förderrinne und der hintere Teil derselben um horizontale Anlenkachsen schwenkbar angelenkt sind. Dadurch, daß die Förderrinne im Bereich unterhalb des Schwenkwerkes ortsfest angeordnet ist, wird bei Höhenverstellung des vorderen Endes und/oder des Abwurfendes der Förderrinne die Höhe des Durchgangsquerschnittes unterhalb des Schwenkwerkes nicht verändert und es kann vor allem auch nicht zu einer Verklemmung von Brocken im Durchgangsquerschnitt unterhalb des Schwenkwerkes kommen. Gemäß der Erfindung liegen zweckmäßig die Anlenkachsen in der Draufsicht.gesehen an den beiden Enden des vom Schwenkwerk überdachten Bereiches oder außerhalb dieses Bereiches.The invention now aims to avoid jamming in the area below the swivel mechanism with certainty and therefore essentially consists in the conveyor trough having a stationary region extending underneath the swivel mechanism, at which the front part of the conveyor trough and the rear part of the same horizontal pivot axes are pivoted. Characterized in that the conveyor trough is arranged in the area below the swivel mechanism, the height of the passage cross section below the swivel mechanism is not changed when the front end and / or the discharge end of the conveyor trough is adjusted and, above all, there is no jamming of chunks in the passage cross section come below the swivel mechanism. According to the invention, the articulation axes are expediently in a plan view, as seen at the two ends of the area covered by the swivel mechanism or outside this area.

In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispieles schematisch erläutert. Die Zeichnung zeigt eine Seitenansicht der Rinne, wobei die Schrämmaschine nur schematisch angedeutet ist.In the drawing, the invention is explained schematically using an exemplary embodiment. The drawing shows a side view of the channel, the cutting machine being indicated only schematically.

Die Förderrinne 1 ist unter dem Schwenkwerk 2 hindurchgeführt. Die untere Begrenzung des Schwenkwerkes ist mit 3 schraffiert angedeutet. In einem Bereich a ist somit die Förderrinne durch die untere Begrenzung 3 des Schwenkwerkes 2 überdacht. In diesem Bereich a weist die Förderrinne 1 einen ortsfesten Teil auf. An den ortsfesten Teil 4 der Förderrinne ist um eine horizontale Schwenkachse 5 schwenkbar ein vorderer Teil 6 der Förderrinne angelenkt und das vordere Ende dieses vorderen Teiles 6 ist um eine Achse 7 schwenkbar an der Laderampe 8 angelenkt. Am rückwärtigen Ende des Bereiches a ist an den ortsfesten Teil 4 der Förderrinne 1 um eine horizontale Schwenkachse 9 schwenkbar der hintere Teil 10 der Förderrinne 1 angelenkt.The conveyor trough 1 is passed under the swivel mechanism 2. The lower limit of the swivel mechanism is indicated by 3 hatched. In a region a, the conveyor trough is thus covered by the lower limit 3 of the swivel mechanism 2. In this area a, the conveyor trough 1 has a stationary part. On the stationary part 4 of the conveyor trough a front part 6 of the conveyor trough is pivoted about a horizontal pivot axis 5 and the front end of this front part 6 is pivoted about an axis 7 on the loading ramp 8. At the rear end of area a is at the stationary part 4 of the conveyor trough 1 pivoted about a horizontal pivot axis 9, the rear part 10 of the conveyor trough 1.

Die Laderampe 8 kann nun in die strichliert dargestellte Stellung 8' gehoben und in die strichliert dargestellte Stellung 8" abgesenkt werden. Damit wird die vordere. Anlenkstelle 7 des schwenkbaren Förderrinnenteiles 6 auch angehoben oder abgesenkt. Der hintere Teil 10 der Förderrinne kann ebenfalls in die Stellung 10' angehoben werden.The loading ramp 8 can now be raised to the position 8 'shown in dashed lines and lowered into the position 8 "shown in dashed lines. The front articulation point 7 of the pivotable conveyor trough part 6 is thus also raised or lowered. The rear part 10 of the conveyor trough can also be moved into the Position 10 'are raised.

Da nun im Bereich a der Förderrinnenteil 4 ortsfest angeordnet ist, verändert sich durch das Anheben der Laderampe 8 und durch das Anheben des Abwurfendes des hinteren Teiles 10 der Förderrinne der Durchgangsquerschnitt unterhalb des Schwenkwerkes 2, d.h. im Bereich a, nicht, so daß die Gefahr eines Steckenbleibens von größeren Brocken im Bereich a ver- mieden ist.Since the conveyor trough part 4 is now arranged in the area a, the passage cross-section below the swivel mechanism 2, i.e. the passage cross section, changes due to the lifting of the loading ramp 8 and the lifting of the dropping end of the rear part 10 of the conveyor trough. in area a, not so that the risk of larger pieces getting stuck in area a is avoided.

Die senkrechte Schwenkachse des Schwenkwerkes ist mit 11 angedeutet. Der Schrämarm 12 ist um eine horizontale mit 13 angedeutete Achse schwenkbar. 14 stellt den Schrämkopf dar.The vertical swivel axis of the swivel mechanism is indicated at 11. The cutting arm 12 can be pivoted about a horizontal axis indicated by 13. 14 represents the cutting head.
