Abstract

The linkage comprises a ternary link with first, second and third pivot connections and a follower link with first and second pivot connections. The first pivot connection of the ternary link is pivotally coupled to the rod end of the bucket actuating hydraulic cylinder. The second pivot connection of the ternary link is pivotally coupled to the excavator bucket. In addition, the excavator bucket is pivotally connected to the dipper stick. The follower link has a first pivot connection that is pivotally connected to the dipper stick and a second pivot connection that is pivotally connected to the third pivot connection of the ternary link. In one frame of reference, the third pivot connection of the ternary link is located between the first and second pivot connections of the ternary link. In addition, the third pivot connection of the ternary link lies above a plane defined by the first and second pivot connections of the ternary link. In another frame the second and third pivot connections of the ternary link define a plane below which the first pivot connection is located. Furthermore, the first pivot connection lies above a second plane which is perpendicular to the first plane and intersects the first plane at the third pivot connection.

Description

Die Erfindung betrifft einen Bagger, insbesondere Heckbagger, mit einem Löffelstiel und einer Schaufel, die mittels eines Hydraulikmotors über ein Gestänge verschwenkt wird.The invention relates to an excavator, in particular a backhoe, with a spoon handle and a shovel, which is by means of a Hydraulic motor is pivoted via a linkage.

Aus den Prospekten "Lokomo hydraulic excavator T340, Druckvermerk 69/10.70-2000-UKp" und dem Prospekt "LOKOMO, Druckvermerk 88-01-71-1000" gehen Bagger mit einem Ausleger und einem daran schwenkbar angebrachten Löffelstiel mit einer Schaufel hervor, die mittels eines Hydraulikzylinders um ein Gelenk geschwenkt wird. Zwischen dem Hydraulikzylinder und der Schaufel erstreckt sich ein Lenker mit drei Lagerstellen, von denen eine mit dem Hydraulikzylinder, eine mit der Schaufel und eine mittlere mit einem zweiten Lenker verbunden ist, der anderenends schwenkbar an dem Löffelstiel gehalten ist.From the brochures "Lokomo hydraulic excavator T340, Printed notice 69 / 10.70-2000-UKp "and the brochure" LOKOMO, Printing reference 88-01-71-1000 "go with a boom and excavator a dipper stick attached to it with a Bucket emerges by means of a hydraulic cylinder Joint is pivoted. Between the hydraulic cylinder and the Shovel extends a handlebar with three bearings, from one with the hydraulic cylinder, one with the shovel and a middle one is connected to a second link which is pivotally held on the other hand on the dipper stick.

Die US-A-2,590,454, US-A-4,768,917 und US-A-2,753,059 offenbaren vergleichbare Gestänge mit dreifachen und zweifachen Lenkern, allerdings für eine frontseitig angeschlossene Laderschaufel, die nach vorne und oben geöffnet ist und somit anderen Bewegungsverhältnissen unterliegt.US-A-2,590,454, US-A-4,768,917 and US-A-2,753,059 reveal comparable booms with triple and double Handlebars, but for a front-connected one Loader bucket that is open to the front and top and thus other movement conditions.

Die US-A-4,381,167 zeigt zudem einen Bagger mit einem dreifachen Betätigungslenker und zwei zweifachen Führungslenkern, die ein Parallelogramm bilden und daher eine Zwangsführung beim Schwenken der Schaufel erzeugen.US-A-4,381,167 also shows an excavator with a triple control arms and two double Guide links that form a parallelogram and therefore one Generate positive guidance when swiveling the bucket.

Das der Erfindung zugrunde liegende Problem wird darin gesehen, daß der Schwenkbereich der Schaufel zu klein ist bzw. beim Arbeiten an einer vertikalen Wand zu hohe Kräfte an der Schaufelspitze auftreten.The problem underlying the invention is seen in that the swivel range of the blade is too small or at Working on a vertical wall too high forces on the Blade tip occur.
