Description
Die Erfindung' betrifft einen Schaufelradbagger mit mehreren gleichachsig zueinander angeordneten, die Abbauwerkzeuge tragenden Rädern, die abwechselnd mit Schaufeleimern und Schneidmessern besetzt sind.The invention relates to a bucket wheel excavator with several coaxial to one another arranged wheels carrying the excavation tools, which alternate with shovel buckets and cutting knives are occupied.
Bei den bekannten Schaufelradbaggern dieser Bauart, die vor Kopf entleeren, sind die Schaufeleimer und die Schneidmesser auf dem Schaufelrad fest angeordnet. Außerdem sind die Eimer nach außen geschlossen, so daß feuchtes Schüttgut in den Eimern leicht haftenbleibt und das Gerät nur für trockenes Schüttgut verwendbar ist.In the known bucket wheel excavators of this type, which empty in front of the head, are the shovel bucket and the cutting knife are fixedly arranged on the paddle wheel. aside from that the buckets are closed to the outside, so that moist bulk material in the buckets is easy adheres and the device can only be used for dry bulk material.
Um auch feuchtes und zum Anhaften neigendes Gut leicht in die Baggereimer einfüllen und aus ihnen entleeren zu können, sollen gemäß der Erfindung die nach außen offenen und in Richtung der lotrechten Schaufelradlängsebene entleerenden Schaufeiao eimer und die die Schaufeleimer oben und seitlich umgreifenden Schneidmesser getrennt voneinander und mit verschiedener Geschwindigkeit umlaufen. Das Verhältnis der Umfangsgeschwindigkeiten der Schneidmesser und der Schaufeleimer wird derart gewählt, daß die Schneidmesser gegenüber den Schaufeleimern um so viel schneller umlaufen, daß sie im unteren grabenden Teil des Schaufelrades dicht vor der Rückwand des Schaufeleimers stehen und im aufsteigenden Teil des Schaufelrades bis über den Scheitelpunkt hinaus sich über die nach außen offenen Schaufeleimer in Richtung der Ausschüttöffnung derart verschieben, daß sie sich vor der Höhe der Oberfläche des in den Eimern sich ansammelnden Gutes befinden und die Schaufeleimer beim Entleeren vollständig freigeben. Die Schaufeleimer sind zweckmäßig mit einer in Richtung der lotrechten Schaufelradlängsebene verlaufenden Austragsschurre versehen. Um ein leichtes Loslösen des Schüttgutes zu ermöglichen, sollen ferner die Seitenwände der Eimer schräg nach außen geneigt sein. Das Schaufelrad und das Messerrad werden zweckmäßigerweise auf einer gemeinsamen Hohlwelle angeordnet, in der die Antriebswelle für das Schaufelrad und das Messerrad gelagert ist. Das Schaufelrad und das Messerrad, die mit Innenverzahnung versehen sind, werden durch an der Hohlwelle gelagerte Zahnräder angetrieben, die mit den auf der Antriebswelle gelagerten Ritzeln kämmen.In order to also easily pour damp and sticky goods into the bucket and to be able to empty from them, according to the invention, the outwardly open and in the direction of the vertical Bucket wheel emptying in the longitudinal plane and the bucket at the top and laterally encompassing cutting knives separated from each other and at different speeds circulate. The ratio of the circumferential speeds of the cutting knife and the shovel bucket is selected in such a way that that the cutting blades rotate so much faster than the shovel buckets, that they are in the lower digging part of the paddle wheel close to the rear wall of the shovel bucket and in the ascending part Part of the paddle wheel to over the apex beyond the after move the open shovel bucket in the direction of the discharge opening so that they are in front of the level of the surface of the material accumulating in the buckets and completely release the bucket when emptying. The shovel buckets are expediently with a longitudinal plane extending in the direction of the vertical blade wheel Discharge chute provided. To enable easy detachment of the bulk material, the side walls of the buckets should also be inclined outwards. The paddle wheel and the knife wheel are expediently arranged on a common hollow shaft, in which the drive shaft for the paddle wheel and the knife wheel is mounted. The paddle wheel and the knife wheel, which are provided with internal teeth, are through Gear wheels mounted on the hollow shaft are driven, which are connected to the on the drive shaft Comb the pinions in bearings.
Durch die Erfindung soll eine lose Schichtung des Baggergutes in den Eimern erreicht werden, so daß ein Zurückbleiben von Baggergut beim Ausschütten vermieden wird. Durch die symmetrische Anordnung der Antriebsräder wird eine vollständig gleichmäßige Beanspruchung sowohl des Verlagerungsgerüstes als auch des Schaufelrades erzielt.The invention is intended to achieve a loose stratification of the dredged material in the buckets so that dredged material is avoided when dumped. The symmetrical arrangement of the drive wheels results in a completely uniform one Stress of both the relocation structure and the paddle wheel achieved.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. An exemplary embodiment of the subject matter of the invention is shown in the drawing.

Das Schaufelrad A ist symmetrisch zur |gtt£ rechten Längsmittelebene, d. h. vor Kopf g$gl Auslegerförderbandes B, angeordnet. Dfi Baggereimer ι sind am Umfang des · auf der Hohlwelle 2 lose drehbar gelagerten Rades 3 angeordnet. Die Schneidmesser 4 sind auf dem Rade 5 befestigt, welches ebenfalls auf der Hohlwelle 2 lose drehbar gelagert ist. In den Lagern 6 und 7, die in der Hohlwelle 2 befestigt sind, ist die Antriebswelle S-drehbar gelagert. Diese trägt die Antriebsritzel 9 und 10, welche mit den Zahnrädern 11 und 12 das Messerrads bzw. das Eimerrad 3 antreiben. Die Zahnräder 11 und 12 sind an der Hohlwelle 2 in den Lager-Schilden 13, 14 gelagert. Das Eimerrad 3 und das Messerrad 5 sind mit entsprechenden Innenkränzen 15, 16 versehen. Die Seitenwände der Schaufeleimer 1 laufen nach dem äußeren Umfang des Schaufelrades 3 zu auseinander, um ein Festkeilen des Baggergutes in den Eimern zu vermeiden. Die Schaufeleimer ι sind mit einer in Richtung der Schaufelradlängsebene verlaufenden Austragsschurre versehen. Über dem Kopfende des Förderbandes 17 ist der Schüttrumpf 18 angeordnet, dessen unteres Rutschblech 19 unr mittelbar an den Umfang des Messerrades 4 angrenzt.The impeller A is symmetrical to | gtt £ right longitudinal center plane, ie before head g $ gl boom conveyor belt B arranged. Dfi excavator buckets 1 are arranged on the circumference of the wheel 3 which is loosely rotatably mounted on the hollow shaft 2. The cutting knives 4 are attached to the wheel 5, which is also loosely rotatably mounted on the hollow shaft 2. The drive shaft S is rotatably supported in the bearings 6 and 7, which are fastened in the hollow shaft 2. This carries the drive pinions 9 and 10, which drive the knife wheel and the bucket wheel 3 with the gears 11 and 12. The gears 11 and 12 are mounted on the hollow shaft 2 in the bearing shields 13, 14. The bucket wheel 3 and the knife wheel 5 are provided with corresponding inner rims 15, 16. The side walls of the bucket 1 diverge towards the outer circumference of the bucket wheel 3 in order to prevent the dredged material from wedging in the buckets. The shovel buckets are provided with a discharge chute running in the direction of the longitudinal plane of the paddle wheel. Arranged above the head end of the conveyor belt 17 is the pouring trunk 18, the lower sliding plate 19 of which is directly adjacent to the circumference of the knife wheel 4.
