   Die Fig. 5 und 6 zeigen eine Ausführungsform, bei der die Zinkengruppen   g   mittels einer Kurbel 8 und einer   Fuhrungastange ? gesteuert   werden, die drehbar an einem exzentrisch zur Achse a   des Wurlrades   in einem Lager p des Gestelles i gelagerten Bolzen befestigt sind. Die Zinkengruppen g sind an ihren   Achsen/in dersell1en Weise   befestigt, wie bei der Ausführungsform gemäss den Fig. 3 und 4, so dass die Zinkengruppen die   Kartoffelmasse   annähernd in deren Schwerpunktachse treffen.

   Durch die Erfindung wird ausser der Entlastung der Steuerungsteile der Vorteil erzielt, dass durch Einschaltung des Armes m der Durchmesser des Wurfrades vergrössert werden kann, wodurch das Wurfrad mit mehr Zinkengruppen ausgestattet und mit einer geringeren Geschwindigkeit betrieben werden kann. Infolgedessen wird der Kraftbedarf der Maschine geringer und deren Empfindlichkeit gegen   Kartoffelkraut   und dgl. herabgesetzt. 
 EMI2.1 
 
1. Wurfrad für Kartoffelerntemaschinen mit gesteuerten Zinken, dadurch gekennzeichnet, dass die Zinkengruppen so zu ihrer Drehachse und zur Hinterkante des Schares liegen, dass der   Druckmittelpunkt   der vom Schar ausgehobenen Erdmasse auf den Zinken annähernd in die Dreh-   aelhse der Zinkengruppen fällt.

   5 and 6 show an embodiment in which the groups of tines g by means of a crank 8 and a guide rod? be controlled, which are rotatably attached to an eccentric to the axis a of the Wurlrades in a bearing p of the frame i mounted bolt. The groups of tines g are fastened to their axes / in the same way as in the embodiment according to FIGS. 3 and 4, so that the groups of tines meet the potato mass approximately in its center of gravity.

   In addition to relieving the load on the control parts, the invention has the advantage that the diameter of the throwing wheel can be increased by engaging the arm m, whereby the throwing wheel can be equipped with more groups of tines and operated at a lower speed. As a result, the power requirement of the machine is lower and its sensitivity to potato tops and the like. Reduced.
 EMI2.1
 
1. Throwing wheel for potato harvesting machines with controlled tines, characterized in that the groups of tines are positioned to their axis of rotation and to the rear edge of the coulter that the center of pressure of the earth mass dug by the coulter on the tines almost falls into the axis of rotation of the groups of tines.
