Die Erfindung betrifft die besondere Ausgestaltung der Druckrollen für Sämaschinen mit am Scharträger einstellbar befestigtem Rollenhalter. Bei den bisher bekannten Einrichtungen war es nicht möglich, die Hubbewegung der Rolle nach unten und oben zu begrenzen. Damit fehlte aber auch die Möglichkeit der Einstellung der Druckrolle für die verschiedenen Boden- und Saatarten. ManThe invention relates to the special design of the pressure rollers for seed drills with adjustable roll holder attached to the coulter holder. With the previously known facilities it was not possible to limit the up and down movement of the roller. But that also meant there was no possibility the setting of the pressure roller for the various types of soil and seed. Man ίο konnte sich bisher nur dadurch dem Boden und Saat anpassen, daß man die Druckrolle auswechselte, was aber auch unbequem und nachteilig für den Betrieb ist.ίο could so far only thereby the ground and Saat adjust that you changed the pressure roller, which is also uncomfortable and is detrimental to operation. Diese Nachteile werden bei der vorliegenden Erfindung durch die besondere Ausbildung des Schwinghebels und seiner Befestigung am Scharträger beseitigt. Die Teile werden erfindungsgemäß so ausgebildet, daß man den Hub oder Anschlag der Druckrolle nach beiden Richtungen begrenzen kann. Zu diesem Zweck wird der Anschlag des Rollenhalters nach unten durch einen festen, und nach oben durch einen einstellbaren Anschlag begrenzt.These disadvantages are in the present invention by the special training the rocker arm and its attachment to the coulter carrier eliminated. According to the invention, the parts are designed so that you can limit the stroke or stop of the pressure roller in both directions. to for this purpose the stop of the roll holder is fixed down by a, and limited upwards by an adjustable stop. Auf der Zeichnung ist ein Ausführungsbei-.spiel dargestellt.The drawing shows an example shown. Abb. ι zeigt die Anbringung der Druckrolle in Vorderansicht,Fig. Ι shows the attachment of the pressure roller in front view, Abb. 2 in Seitenansicht.Fig. 2 in side view. Der Arm α trägt in bekannter Weise die Saatgutschare b. Die Druckrolle c ist zweckmäßig aus Holz gefertigt und an einer Gabel d befestigt, die sich um den Bolzen / dreht. Dieser Bolzen sitzt an dem mit Skala versehenen Flacheisen h, das mit dem Hebel α durch die Schelle k verbunden ist. Durch Lösen der Schelle kann man das Flacheisen h und den Hebel α beliebig gegeneinander verschieben. Der Ausschlag der Rolle c ist nach unten begrenzt durch den Stift/. Die Begrenzung nach oben wird durch den Haken m gebildet, der gleichfalls auf dem Flacheisen h drehbar ist und durch dessen Verstellung also die Saattiefe geregelt wird.The arm α carries the seed coulters b in a known manner. The pressure roller c is expediently made of wood and attached to a fork d that rotates around the bolt /. This bolt sits on the flat iron h, which is provided with a scale and which is connected to the lever α by the clamp k . By loosening the clamp you can move the flat iron h and the lever α against each other as desired. The deflection of roller c is limited at the bottom by the pin /. The upward limit is formed by the hook m , which can also be rotated on the flat iron h and which is adjusted to regulate the sowing depth.
