Druckrollenanordnung an Drillmaschinen.Pressure roller arrangement on seed drills. Patentiert im Deutschen Reiche vom 27. Januar 1926 ab.Patented in the German Empire on January 27, 1926.

Bei den Drillmaschinen ist es erforderlich,With the seed drills it is necessary

daß die Druckrollen genau in den von den Drillscharen erzeugten Furchen laufen, ran die ausgesäten Körner in den Boden zu drükken. Diese Aufgabe kann bei den bisherigen Druckrollenanordnungen nicht immer erfüllt werden. Die Druckrollen sind allgemein am Drillhebel selbst gelagert, und beim Besäen von Abhängen, falls sich, die Drillmaschinethat the pressure rollers run exactly in the furrows created by the seed coulters to press the sown grains into the ground. This task can be done with the previous Pressure roller arrangements are not always met. The pressure rollers are generally on The drill lever itself is stored, and when sowing slopes, the seed drill, if possible

ίο quer zu denselben bewegt, erfolgt nun infolge der Schwerkraft eine Schrägstellung des Schars und der Rollen zur Bewegungsrich,-tung. Durch diese Schrägstellung können Schar und Rollen nicht mehr genau spuren und letztere ihren Zweck nicht erfüllen. Um diesen Übelstand zu beheben, werden gemäß der Erfindung die Druckrollen unabhängig von den Scharen verstellbar angeordnet, und zwar so, daß eine seitliche Verschiebung der Rollen auch während des Betriebes erfolgen kann, soίο moved transversely to the same, now takes place as a result gravity an inclined position of the coulter and the rollers to the direction of movement. As a result of this inclination, the coulter and rollers can no longer trace precisely and the latter cannot fulfill their purpose. To this one To remedy the problem, according to the invention, the pressure rollers are arranged to be adjustable independently of the flocks so that a lateral displacement of the roles can also take place during operation, so

Zu diesem Zwecke lagern die Druckrollen gemeinsam an einem beweglichen Gestänge.For this purpose, the pressure rollers are stored together on a movable linkage.

In der Zeichnung ist die Erfindung in Abb. ι von der Seite dargestellt, in Abb. 2 von oben.In the drawing, the invention is shown in Fig. Ι from the side, in Fig. 2 from above.

α ist eine der Druckrollen, b der Druckrollerihebel, welcher die Druckrollen rahmenartig trägt. Sämtliche Druickrollenhebel sind mit ihrem anderen freien Ende auf einer gemeinsamen querliegenden Stange c befestigt. Diese Befestigung kann leicht lösbar ausgebildet werden, um auch eine gesonderte seitliche Verstellung bei eventueller Verbiegimg eines Scharhebels vornehmen zu können. Die gemeinsame Verstellung erfolgt am zweckmäßigsten durch eine Schraubenspindel, die in bekannter Weise durch Kurbeln o.dgl. und unter Anwendung geeigneter Übertragungselemente (Zahnräder, Kegelräder o. dgl.) ge α is one of the pressure rollers, b the pressure roller lever, which carries the pressure rollers like a frame. All pressure roller levers are fastened with their other free end on a common transverse rod c . This attachment can be designed to be easily detachable in order to be able to carry out a separate lateral adjustment in the event of a possible bending of a coulter lever. The common adjustment is most expediently done by a screw spindle, which in a known manner by cranks or the like. and using suitable transmission elements (gears, bevel gears, or the like) ge

Durch die Selbsthemmung der Spindelmutter werden die Rollen in ihrer jeweilig eingestellten Lage oder Fahrtrichtung 25 gehalten.is rotated, so that by means of a nut and possibly a switching lever, d the lateral displacement of the rod c and thus the pressure roller a takes place. Due to the self-locking of the spindle nut, the rollers are held in their respective set position or direction of travel 25.
