Description
Greifer in den verschiedensten Ausführungen und für die verschiedensten' Zive@, z. B: zur Beförderu:irg von Sand, Kohle, Heu, Dung usw., sind bekannt. Die Greifer, die in ihrer Konstruktion Hier Beschaffenheit des jeweiligen Fördergutes,angepaßt sind, dringen in manchen Fällen, z. B: bei Sand, Kohle usw., durch ihr Gewic'h@t in das Fördergut ein. Bei fester liegendem Fördergut müssen die Greifer von Hand oftma;Is unter bedeutendem Kräfteaufwand in das Gut hineingedrückt werden.Grippers in a wide variety of designs and for a wide variety of ' Zive @, e.g. B: for the transport of sand, coal, hay, dung etc. are known. the Grippers, which in their construction are adapted to the nature of the respective conveyed goods are, in some cases, e.g. B: in the case of sand, coal, etc., by their weight into the conveyed good. If the conveyed material is more solid, the grippers must be manually oftma; Is be pressed into the good with considerable expenditure of force.
Das Schließen des Greifers geschieht beim Hoc'hziehen mechanisch durch Seile, Hebelarme o. dgl. Die Erfindung dient in erster Linie Landwirtschaftlichen Zwecken und ist daher durch eine diesen Verhältnissen angepaßte leichte Bauart ausgezeichnet, welche auch ihre Anbringung an einem der üblichen Trecker gestattet. Die Hebevorrichtung gemäß der Erfindung besteht aus einem ummittelbar am Kopf eines Auslegers aufgehängten, hydraulisch gesteuertenGreifer, wobei, der Zylinder an der Auslegerspitze senkrecht und drehbar aufgehängt und über Laschen E starr mit der Drehachse 2 der Greifarme A verbunden ist und der Kolben über Lenker B die Greifarme steuert. Dabei ist der Ausleger in jeder Höhenlage in Höhenrichtung hydraulisch oder mechanisch feststellbar. Insbesondere -ist die Erfindung für den Anbau an einem Trecker geeignet.The gripper closes mechanically when it is pulled up Ropes, lever arms or the like. The invention is primarily used for agricultural purposes Purposes and is therefore characterized by a lightweight design adapted to these conditions, which also allows it to be attached to one of the usual tractors. The lifting device according to the invention consists of a directly suspended at the head of a boom, hydraulically controlled grab, where, the cylinder at the boom tip is vertical and rotatably suspended and rigidly connected to the axis of rotation 2 of the gripping arms via straps E A is connected and the piston controls the gripping arms via handlebar B. Here is the Boom can be locked hydraulically or mechanically in height direction at any height. In particular, the invention is suitable for attachment to a tractor.
In der Zeichnung ist in Abb. I und II ein Dunggreifer dargestellt, der -an dem Ausleger eines hydraulisch betriebenen Kranes montiert ist.In the drawing, a manure grabber is shown in Fig. I and II, which is mounted on the boom of a hydraulically operated crane.
Der Greifer, der hier mit acht Zinken A dargestellt wird,, ist durch die Lenker B mit dem Kolben C des Oldruckzylinders D verbunden.The gripper, shown here with eight prongs A, is through the handlebars B connected to the piston C of the oil pressure cylinder D.
Der Zylinder D trägt an seinem unterer! Ende i .die Laschen E. Diese Laschen E tragen am unteren Ende die Achse :2 für die Greiferzinken.The cylinder D carries on its lower one! End i. The tabs E. This Lugs E carry the axle at the lower end: 2 for the gripper tines.
Der Greifer ist an der Spitza3 des Auslegers F aufgehängt. An .der .Auslegerspitze 3 isst ebenfalls der Verbindungsschlauch der Oldruckleitung.in den Druckzylinder D eingeführt. Der ganze Greifer findet seinen Gegenhalt an dem Ausfeger. Dieser Ausleger kann hydraulisch oder auch mechanisch in der gewünschten Stellung festgesetzt werden.The gripper is suspended from the point a3 of the boom F. At the The jib tip 3 is also fed into the connecting hose of the oil pressure line Impression cylinder D introduced. The whole gripper finds its counter-hold on the sweeper. This boom can be hydraulically or mechanically in the desired position be fixed.
Durch entsprechende Schaltung der' Ventile in der Öldruckleitung werden die Zinken; des Greifers von der Kolbenstange C durch Vermittlung der Lenker B auseinandergezogen (gestrichelte Zinken). Der Ausleger des Kranes wird so weit gesenkt, daß der Greifer auf den Dung aufsetzt (Abb. III).By switching the valves in the oil pressure line accordingly the prongs; of the gripper pulled apart from the piston rod C through the intermediary of the handlebars B. (dotted teeth). The boom of the crane is lowered so that the grab touches the manure (Fig. III).
Durch die entsprechende hydraulische Steuerung werden die Zinken .dann in den Dung hineingedrückt und zusammengezogen. Daraufhin hebt der Kran den gefüllten Greifer 'hoch.The tines are then .then pressed into the dung and pulled together. The crane then lifts the filled one Grapple up.
