Description

Löffelbagger mit am heb- und senkbaren Ausleger gelenkig sitzendem Löffelstiel. Die Erfindung betrifft einen Löffelbagger mit an einem heb- und senkbaren Ausleger gelenkig sitzendem Löffelstiel, dessen unteres Ende den starren Löffel mit Klappboden trägt.Backhoe with articulated seat on the boom that can be raised and lowered Dipperstick. The invention relates to a backhoe with one that can be raised and lowered Outrigger articulated dipperstick, the lower end of which is the rigid spoon with hinged bottom.

Ausleger und Löffelstiel werden durch ein Hebeseil geführt, das unmittelbar auf den Stiel und durch diesen auf den Ausleger einwirkt, während die Einzelbewegungen des Löffels durch ein zweites Seil geleitet werden, das als Schleppseil dient.The boom and arm are guided by a lifting rope that immediately acts on the stick and through this on the boom, during the individual movements of the bucket can be guided through a second rope that acts as a tow rope.

Das Neue des Löffelbaggers besteht darin, claß am oberen Ende des Löffelstiels ein besonderes Zwischenglied (i6) als Tragarm für die Rolle des Hebeseils aasgelenkt ist, um zu verhindern, daß das Hebeseil und der Gelenkbolzen, durch den der Stiel mit dem Ausleger verbunden ist, sich gegenseitig stören. Dieser Tragarm für die Rolle hat eine solche Länge und Gestalt, daß er, wenn die Zugrichtung des Hebeseils mit dem Löffelstiel einen spitzesten Winkel bildet, in jeder vorkommenden Arbeitsstellung über den Gelenkbolzen des Stieles hinübergreift. Hierdurch wird ein Scheuern des Hebeseils am Gelenkbolzen vermieden und ein größerer Ausschlagwinkel für den Löffelstiel ermöglicht. In den Zeichnungen zeigen Abb. i die Seitenansicht eines Teiles des Löffelbaggers, Abb. 2 den Aufriß des vorderen Endes des Auslegers mit Stiel und Schleppseil sowie Seil zur Auslösung des Klappbodens.The novelty of the backhoe is that it is at the top end of the Dipper handle a special intermediate link (i6) as a support arm for the role of the lifting rope is articulated in order to prevent the lifting rope and the hinge pin through the the stick is connected to the boom, interfere with each other. This support arm for the role has such a length and shape that when the direction of pull of the The lifting rope forms the most acute angle with the dipperstick, in every occurring Working position reaches over the hinge pin of the handle. This will Avoid chafing of the lifting rope on the hinge pin and a larger angle of deflection for the dipperstick. In the drawings, Fig. I shows the side view of a part of the backhoe, Fig. 2 is an elevation of the front end of the boom with handle and tow rope as well as rope to release the hinged floor.

Der Ausleger 2 ist mit Bolzen 4 heb- und senkbar an der Säule 3 gelagert, die um ein Paar senkrechter Zapfen im Hauptgerüst A schwenkbar ist. Am äußeren Ende sind Laschen 5 aufgenietet, die den Gelenkzapfen 6 für den Stiel tragen. Die Lagerböcke 7 für den Gelenkbolzen 6 sind mit Bolzen 8 und Nieten 9 an den Flanschen io der Träger ii befestigt, die, durch Laschen 13 verbunden, den Stiel 12 bilden.The boom 2 can be raised and lowered by bolts 4 on the column 3, which can be pivoted about a pair of vertical pins in the main frame A. At the outer end tabs 5 are riveted, which carry the pivot pin 6 for the handle. The bearing blocks 7 for the hinge pin 6 are fastened with bolts and rivets 8 9 to the flanges of the carrier io ii, which are connected by tongues 1 3 form the stem 12th

Am oberen Ende trägt der Stiel 12, auf der dein Ausleger 2 abgewendeten Seite Laschen i-. mit dem Lager für den Gelenkbolzen 15 eines zwischengeschalteten Winkelhebels 16, der die Seilrolle 17 für das Hebeseil 18 trägt. Der Winkelhebel 16, der in jeder Stellung Tiber die Gelenkverbindung zwischen Ausleger und Stiel hinübergreift, bildet ein Merkmal der Erfindung. Seine Wirkung besteht darin, daß sich das Seil 18 in keiner Stellung des Auslegers und des Stieles am Gelenkbolzen 6 scheuern kann. Am unteren Ende trägt der Stiel mittels starrer Laschen i9 und Streben 2o den Löffel ei.At the upper end of the handle 12, on the side facing away from your boom 2, tabs i-. with the bearing for the hinge pin 15 of an intermediate angle lever 16 which carries the pulley 17 for the lifting rope 18. The angle lever 16, which engages over the articulated connection between boom and stick in every position, forms a feature of the invention. Its effect is that the rope 18 cannot rub against the hinge pin 6 in any position of the boom and the handle. At the lower end, the handle supports the spoon by means of rigid straps and struts 20.
