Abstract

The invention relates to a hydraulically actuable lever system for a loader in the form of a shovel of an approximately semicircular design, which is suitable for picking up and dumping snow, there being a first lever provided in an articulated manner at the upper end of the shovel and a second lever adjoining the first lever in a likewise articulated manner and arranged pivotably on a bracket of the lever system, and a hydraulic cylinder being arranged between the bracket and the first lever for the actuation of the lever system. This lever system is characterized in that the hydraulic cylinder 39 is articulated by its piston rod in the middle region of the first lever 36, the first lever 36 is bent outwards and the shovel is guided in a supporting frame. <IMAGE>

Nr. 390 981 Die Erfindung betrifft ein hydraulisch betätigbares Hebelsystem für ein Ladegerät in Form einer etwa halbkreisförmig ausgebildeten Schaufel, die zum Aufnehmen und Kippen von Schnee geeignet ist, wobei am oberen Ende der Schaufel gelenkig ein erster Hebel vorgesehen ist, an den sich ebenfalls gelenkig ein zweiter Hebel anschließt, der auf einer Konsole des Hebelsystems schwenkbar angeordnet ist, und wobei zwischen der Konsole und dem ersten Hebel ein Hydraulikzylinder zur Betätigung des Hebelsystems angeoidnet ist Bei bekannten Schneeaufnehmem und Pflügen wird das Schneeaufhehmen und Kippen umständlich mit einer Seilwinde durchgeführt. Fernerhin ist es bei bekannten derartigen Hebelsystemen in nachteiliger Weise nicht möglich, gut wirkende Hydraulikzylinder vorzusehen. Die Führung der Schaufel solcher bekannter Ladegeräte ist meist nicht stabil genug, um allen derartigen Belastungen standhalten zu können. Die Erfindung zielt darauf ab, alle oben genannten Nachteile zu vermeiden und auch die Benutzung gut wirkender Hydraulikzylinder jedenfalls zu ermöglichen, was für einen zweckentsprechenden Betrieb erforderlich ist Diese Aufgabe wird bei einem Hebelsystem der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß der Hydraulikzylinder mit seiner Kolbenstange im mittleren Bereich des ersten Hebels angelenkt ist, der erste Hebel nach außen gebogen ist und die Schaufel in einem Stützgestell geführt ist. In der Zeichnung ist der Gegenstand der Erfindung in einer Ausführungsform im wesentlichen schematisch dargestellt. Die Fig. 1 und 2 veranschaulichen verschiedene Arbeitsstellungen der erfindungsgemäßen Einrichtung, Fig. 3 ist eine Seitenansicht Fig. 1 zeigt die Schaufel (1) in der Kippstellung mit ausgefahrenem Hydraulikzylinder (39) und gestreckten Hebeln (34), (36). Fig.No. 390,981 The invention relates to a hydraulically actuated lever system for a charger in the form of an approximately semicircular shovel, which is suitable for picking up and tipping snow, with a first lever being articulated at the upper end of the shovel, which is also articulated a second lever connects, which is arranged pivotably on a bracket of the lever system, and wherein a hydraulic cylinder for actuating the lever system is anoided between the bracket and the first lever. In known snow pickups and plows, snow picking up and tipping is laboriously carried out with a cable winch. Furthermore, in known lever systems of this type, it is disadvantageously not possible to provide hydraulic cylinders that work well. The guide of the shovel of such known chargers is usually not stable enough to withstand all such loads. The invention aims to avoid all of the disadvantages mentioned above and to enable the use of well-acting hydraulic cylinders, which is necessary for an appropriate operation. This object is achieved according to the invention in a lever system of the type mentioned in that the hydraulic cylinder with its piston rod is articulated in the central region of the first lever, the first lever is bent outwards and the blade is guided in a support frame. In the drawing, the subject matter of the invention is shown essentially schematically in one embodiment. 1 and 2 illustrate various working positions of the device according to the invention, Fig. 3 is a side view. Fig. 1 shows the bucket (1) in the tilted position with the hydraulic cylinder (39) extended and the levers (34), (36) extended. Fig. 2 veranschaulicht die Schaufel in der Schneeaufnahmeposition, wobei der Hydraulikzylinder (39) eingefahren ist und die beiden bei (35) gelenkig miteinander verbundenen Hebel (34), (36) wie eine Schere zusammengezogen sind. Aus Fig.2 illustrates the shovel in the snow holding position, the hydraulic cylinder (39) being retracted and the two levers (34), (36) articulated together at (35) being pulled together like scissors. From Fig. 3 ist die Vorderansicht einer Konsole (31) zu ersehen, wo der Hydraulikzylinder (39) bei (33) angelenkt ist. Zwei Hebelbeine (44) des Hebels (34) sind an derselben Konsole (31) bei (32) angelenkt. Die von einem Stützgestell (5) ausgehende Konsole (31) ist beidseitig zusätzlich gegen eine Stützplatte (6) abgestützt siehe auch Fig. 3, Abstützung (45). Auf der Konsole (31) sind, wie gesagt, zwei Hebelbeine (44) des Hebels (34) angelenkt der oben mit dem Hebel (36) gelenkig verbunden ist Der erste Hebel (36) ist an der Schaufel (1) bei (38) gelenkig befestigt. Der doppelt wirkende Hydraulikzylinder (39), der an der Konsole (31) bei (33) gelagert ist führt zum zweiten Hebel (36), wo der Hydraulikzylinder (39) bei (37) angelenkt ist Wird nun der Hydraulikzylinder (39) ausgefahren, werden die beiden in Scherenstellung zueinander stehenden Hebel (34), (36), Fig. 2, gestreckt (siehe auch Fig. 1) und die am Stützgestell (5) geführte Schaufel (1) in die Kippstellung nach Fig. 1 gebracht. Zum Schneeaufnehmen wird der Hydraulikzylinder (39) (Fig. 2) eingefahren und die beiden Hebel (34), (36) werden wie eine Schere zueinander gezogen (Fig. 2) und der Schnee wird mit der Schaufel (1) aufgenommen. PATENTANSPRUCH Hydraulisch betätigbares Hebelsystem für ein Ladegerät in Form einer etwa halbkreisförmig ausgebildeten Schaufel, die zum Aufnehmen und Kippen von Schnee geeignet ist, wobei am oberen Ende der Schaufel gelenkig ein erster Hebel vorgesehen ist an den sich ebenfalls gelenkig ein zweiter Hebel anschließt der auf einer Konsole des Hebelsystems schwenkbar angeordnet ist, und wobei zwischen der Konsole und dem ersten Hebel ein Hydraulikzylinder zur Betätigung des Hebelsystems angeordnet ist, dadurch gekennzeichnet, daß der Hydraulikzylinder (39) mit seiner Kolbenstange im mittleren Bereich des ersten Hebels (36) angelenkt ist (bei (37)), der erste Hebel (36) nach außen gebogen ist und die Schaufel (1) in einem Stützgestell (5) geführt ist. Hiezu 2 Blatt Zeichnungen -2-3 shows the front view of a bracket (31) where the hydraulic cylinder (39) is articulated at (33). Two lever legs (44) of the lever (34) are articulated on the same bracket (31) at (32). The console (31) extending from a support frame (5) is additionally supported on both sides against a support plate (6), see also FIG. 3, support (45). As already mentioned, two lever legs (44) of the lever (34) are articulated on the console (31) and are connected in an articulated manner to the lever (36) at the top. The first lever (36) is on the blade (1) at (38) articulated attached. The double-acting hydraulic cylinder (39), which is mounted on the bracket (31) at (33), leads to the second lever (36), where the hydraulic cylinder (39) is articulated at (37) If the hydraulic cylinder (39) is now extended, the two levers (34), (36), FIG. 2, which are in the scissor position relative to each other, are stretched (see also FIG. 1) and the blade (1) guided on the support frame (5) is brought into the tilted position according to FIG. To pick up snow, the hydraulic cylinder (39) (Fig. 2) is retracted and the two levers (34), (36) are pulled together like scissors (Fig. 2) and the snow is picked up with the shovel (1). PATENT CLAIM Hydraulically actuated lever system for a charger in the form of an approximately semicircular shovel, which is suitable for picking up and tipping snow, whereby a first lever is articulated at the upper end of the shovel, which is also articulated and connected to a second lever on a console of the lever system is pivotably arranged, and wherein a hydraulic cylinder for actuating the lever system is arranged between the bracket and the first lever, characterized in that the hydraulic cylinder (39) is articulated with its piston rod in the central region of the first lever (36) (at ( 37)), the first lever (36) is bent outwards and the blade (1) is guided in a support frame (5).
