Das Material wird von einem LKW in den Kübel gekippt, von dort über einen Förderer zu einer Verteilerschnecke vor der Einbaubohle gefördert, von der Verteilerschnecke über die Einbaubreite verteilt und mittels der Einbaubohle, die Stampf- und/oder Vibrationsaggregate umfassen kann, eingebaut. Die Einbaubohle besteht dabei aus einer Grundbohle und zwei gegenüber der Grundbohle seitlich ausfahrbaren Ausfahrbohlen zur Verbreiterung der Einbaubreite, vgl. z.B. DE-U-9 204 559.Asphalt pavers usually comprise a chassis which is usually provided with a crawler chassis, which is provided at the front with a bucket for receiving the material to be installed and at the rear with a screed. The material is tipped into the bucket by a truck, conveyed from there via a conveyor to a spreading auger in front of the screed, distributed by the spreading auger over the pave width and installed by means of the screed, which can include ramming and / or vibration units. The screed consists of a base screed and two extendable screeds that can be extended laterally compared to the base screed to broaden the pave width, cf. e.g. DE-U-9 204 559.

Ein entsprechender Straßenfertiger, bei dem der Kübel schwenkbare und gegebenenfalls teleskopierbare Seitenwandabschnitte aufweist, ist ferner aus DE-U-9 109 496 bekannt.A corresponding paver, in which the bucket has pivotable and optionally telescopic side wall sections, is also known from DE-U-9 109 496.

Häufig werden neben fertigen oder im Bau befindlichen Straßen Gräben ausgehoben, die anschließend wieder zu schließen sind, oder es müssen Bankette angelegt werden. Dies kann zwar u.U. unter Einsatz eines derartigen Straßenfertigers dadurch geschehen, daß dieser über den Graben- bzw. den Bankettbereich, diesen zwischen rechtem und linkem Fahrwerk befindlich, hinweggeführt wird, jedoch ist häufig hierzu das Gelände nicht geeignet oder kein genügender Platz vorhanden.Trenches are often dug next to finished or under construction roads, which must then be closed again, or banquets have to be built. This may when using such a paver, this is done by leading it over the ditch or the banquet area, which is located between the right and left running gear, but the terrain is often not suitable for this or there is insufficient space.

Aufgabe der Erfindung ist es daher, einen Straßenfertiger der eingangs genannten Art zu schaffen, mit dem es möglich ist, seitlich von einer Fahrbahn befindliche Gräben zu schließen oder Bankette anzulegen, ohne daß Gelände- oder Platzprobleme auftreten.The object of the invention is therefore to provide a paver To create the type mentioned above, with which it is possible to close trenches located to the side of a roadway or to create banquets without problems of terrain or space.

Diese Aufgabe wird dadurch gelöst, daß auf dem bodenseitig offenen Kübel ein bodenseitig geschlossener Kübel aufliegt, wobei der bodenseitig geschlossene Kübel um eine sich in Fahrtrichtung erstreckende Achse zu einer Seite des Straßenfertigers hin abkippbar ist, und daß an der Seite, zu der der bodenseitig geschlossene Kübel abkippbar ist, ein in Fahrtrichtung vor der entsprechenden Ausfahrbohle befindlicher Abstreifer an dieser angebracht ist.This object is achieved in that a bucket which is closed on the bottom rests on the bucket which is open at the bottom, the bucket which is closed on the bottom being able to be tilted about an axis extending in the direction of travel to one side of the paver, and on the side to which the bottom is closed Bucket can be tilted, a scraper located in front of the corresponding extension screed is attached to it.

Der dargestellte Straßenfertiger umfaßt ein Fahrgestell 1, das mit einem mit Rädern oder wie dargestellt mit einer rechten und einer linken Fahrwerkskette 2 versehenes Fahrwerk, einem Fahrerstand 3 und einer Einbaubohle 4 versehen ist. Von einem frontseitig vorhandenen Kübel 5, der zu einem von der Vorderseite des Straßenfertigers unter dem Fahrerstand 3 hindurch zu einer Verteilerschnecke vor der Einbaubohle 4 führenden Förderer (nicht dargestellt) bodenseitig offen ist, sind die normalerweise vorhandenen, klappbaren, einen Einfülltrichter bildenden Seitenwandteile, die durch entsprechende, an darunter befindlichen, feststehenden Seitenwandteilen 6 des Kübels 5 angelenkte Hydraulikzylinder verschwenkt werden können, zum Schließen von Gräben oder Herstellen von Banketten o.dgl. entfernt. Auf dem nach der Entfernung der klappbaren Seitenwandteile verbleibenden (Rest-)Kübel 5 liegt ein bodenseitig geschlossener Kübel 7 auf, der mittels eines Hydraulikzylinders 8 zu einer Seite, hier zur rechten Seite hin kippbar ist. Der Hydraulikzylinder 8 ist dazu an der linken Seite unterhalb des Kübels 6 sowie im Seitenbereich des Kübels 5, beispielsweise an dem entsprechenden feststehenden Seitenwandteil 6 des Kübels 5, angelenkt. Der Kübel 7 stützt sich beim Kippen auf der rechten oberen Seitenkante des entsprechenden feststehenden Seitenwandteils 6 des Kübels 5 auf. Dort können entsprechende Scharniere 9 angeordnet sein, die den Kübel 7 abstützen. Der Kübel 7 besitzt an der rechten Seite eine verschließbare sowie - im dargestellten Ausführungsbeispiel um ihre Oberkante - verschwenkbar angeordnete Seitenwand 10. Nach Lösen der Seitenwand 10 öffnet sich diese beim Kippen des Kübels 7, so daß im Kübel 7 befindliches Material 11 seitlich in einen Graben- oder Bankettbereich 12 abgekippt wird.The road paver shown comprises a chassis 1 which is provided with a chassis provided with wheels or, as shown, with a right and a left chassis chain 2, a driver's station 3 and a screed 4. From the front of a bucket 5, which is open to the bottom of a conveyor (not shown) leading from the front of the paver under the driver's cab 3 to a distributor auger in front of the screed 4, the normally available, foldable, side wall parts forming a hopper are the can be pivoted by means of corresponding hydraulic cylinders which are articulated on fixed side wall parts 6 of the bucket 5 underneath, for closing trenches or producing banquets or the like. away. On the (residual) bucket 5 remaining after removal of the foldable side wall parts there is a bucket 7 which is closed at the bottom and which can be tilted to one side, here to the right side, by means of a hydraulic cylinder 8. For this purpose, the hydraulic cylinder 8 is on the left side below the bucket 6 and in the side region of the bucket 5, for example on the corresponding fixed one Side wall part 6 of the bucket 5, articulated. The bucket 7 is supported when tilting on the right upper side edge of the corresponding fixed side wall part 6 of the bucket 5. Corresponding hinges 9, which support the bucket 7, can be arranged there. The bucket 7 has on the right side a closable and - in the illustrated embodiment around its upper edge - pivotally arranged side wall 10. After loosening the side wall 10, this opens when the bucket 7 is tilted, so that material 11 located in the bucket 7 laterally into a trench - or banquet area 12 is tilted.

Die Einbaubohle 4 umfaßt eine nach rechts ausfahrbare Ausfahrbohle 13 und eine nicht dargestellte, nach links ausfahrbare Ausfahrbohle, um die Einbaubreite des Straßenfertigers entsprechend verbreitern zu können.The screed 4 comprises a screed 13 which can be extended to the right and a screed which is not shown, which can be extended to the left, in order to be able to widen the pave width of the paver accordingly.

An der Außenwange 14 der rechten Ausfahrbohle 13 ist zur Schließung eines Grabens oder zur Herstellung eines Banketts mittels eines nach vorne gerichteten Arms 15 ein Abstreifer 16 - gegebenenfalls höheneinstellbar - befestigbar. Der Abstreifer 16 umfaßt eine Rückwand 17 und zwei Seitenwände 18. Die Rückwand 17 des Abstreifers 16 ist durch einen Hydraulikzylinder 19 in der Breite verstellbar. Das vom Kübel 7 abgekippte Material wird mittels des Abstreifers 16, in der gewünschten Breite durch die Seitenwände 18 eingestellt, in der gewünschten Höhe bei entsprechend ausgefahrener Ausfahrbohle 13 abgestreift.On the outer cheek 14 of the right extending screed 13, a scraper 16 - optionally adjustable in height - can be fastened by means of a forwardly directed arm 15 in order to close a trench or to produce a banquet. The scraper 16 comprises a rear wall 17 and two side walls 18. The width of the rear wall 17 of the scraper 16 can be adjusted by means of a hydraulic cylinder 19. The material tipped from the bucket 7 is adjusted by means of the scraper 16, in the desired width through the side walls 18, at the desired height with the extending screed 13 extended accordingly.

Der Kübel 7 reicht zur Materialabgabeseite hin um einiges über die Breite des Straßenfertigers hinaus, und zwar insbesondere so, daß im wesentlichen etwa auf der Breite der Außenseite der ausgefahrenen Ausfahrbohle 13 abgekippt wird. Zur symmetrischen Belastung des Straßenfertigers reicht der Kübel 7 zweckmäßigerweise auch zur anderen Seite entsprechend weit über die Breite des Straßenfertigers hinaus.The bucket 7 extends towards the material discharge side by a lot beyond the width of the paver, in particular in such a way that it tilts substantially on the width of the outside of the extended extension screed 13. For the symmetrical loading of the paver, the bucket 7 also expediently extends far beyond the width of the paver on the other side.

Zur Betätigung des Hydraulikzylinders 19 für die Arbeitsbreite des Abstreifers 16 kann der Hydraulikkreis, der normalerweise für die Verstellung der einen nun still liegenden Ausfahrbohle dient, verwendet werden, während für die Betätigung des Hydraulikzylinders 8 für das Kippen des Kübels 7 die Hydraulik der normalerweise vorhandenen, klappbaren Seitenwandteile des Kübels 5 verwendet werden kann.To actuate the hydraulic cylinder 19 for the working width of the scraper 16, the hydraulic circuit, which is normally used for the adjustment of the now-lying extending screed, can be used, while for the actuation of the hydraulic cylinder 8 for tilting the bucket 7, the hydraulics of the normally existing, foldable side wall parts of the bucket 5 can be used.
