Description

Gegenstand der Erfindung ist eine Druckrolle mit selbsttätiger Regelung der Senktiefe, wie solche hauptsächlich durch das deutsche Patent 324464 geschützt ist.
Durch die verschiedenartige Ausführung und Lagerung der Drillscharhebel h je nach Länge, Stärke und Abstand vom Boden ist die nach Patent 324464 beispielsweise dargestellte Anbringung des Druckrollenhebelarmes α bei verschiedenen Drillmaschinensystemen sehr schwierig und z. T. unmöglich. Der Druckrollenhebelarm b und der Abstützhebel d müßten je nach dem Abstand der Scharträger vom Boden verschiedenartige Längen erhalten, und die Anlagerung müßte sich nach Form und Stärke der verschiedenartigen Scharträger richten, dadurch wird der Abstand der Druckrolle vom Drillschar ungleichmäßig und die Führung der Druckrolle ao ungenau; außerdem versagt das Abstützen des Hebelarmes sehr leicht.The subject of the invention is a pressure roller with automatic control of the countersink depth, as is mainly protected by German patent 324464.
Due to the different design and storage of the drill coulter lever h depending on the length, strength and distance from the ground, the attachment of the pressure roller lever arm shown in patent 324464, for example, α in different seed drill systems is very difficult and z. T. impossible. The pressure roller lever arm b and the support lever d would have to have different lengths depending on the distance between the coulter carriers and the ground, and the deposition would have to be based on the shape and strength of the different coulter carriers, so the distance between the pressure roller and the drill coulter becomes uneven and the guidance of the pressure roller ao inaccurate ; in addition, the support of the lever arm fails very easily.

Demgegenüber zeigt der Erfindungsgegenstand ein Abstützen des Hebelarmes ο an einem einheitlichen Traghebel /, der eine Veras längerung des Scharträgers darstellt. Dieser Traghebel / läßt sich an die verschiedenartigsten Scharträger — auch als Ersatz für dieselben — auf einfache Weise befestigen und ermöglicht erst eine gleichmäßige Abmessung und einheitliche Anlagerung des Hebelarmes a. Der Abstand zwischen Druckrolle und Drillschar wird verkürzt und damit die Führung der Druckrolle verbessert.In contrast, the subject matter of the invention shows a support of the lever arm ο on a uniform support lever /, which represents an extension of the coulter carrier. This support lever / can be attached to a wide variety of coulter carriers - also as a replacement for the same - in a simple manner and only enables uniform dimensions and uniform attachment of the lever arm a. The distance between the pressure roller and the drill coulter is shortened and thus the guidance of the pressure roller is improved.

Das Abstützen des Hebelarmes α zur Saattiefenregelung — Einwirkung auf den Tiefgang des Drillschars — erfolgt gleichfalls am Traghebel / durch den Stützhebel d, dessen vertikale Ausschwingung durch einen Schlitz oder eine ähnliche Anordnung auf einem Bolzen des Traghebels federnd begrenzt wird und der Druckrolle eine sichere Führung gibt. Das Abstützen kann auch mit gleicher Wirkung in umgekehrter Weise vom Traghebel aus erfolgen.The support of the lever arm α for sowing depth control - acting on the depth of the drill coulter - is also carried out on the support lever / by the support lever d, the vertical oscillation of which is resiliently limited by a slot or a similar arrangement on a bolt of the support lever and provides the pressure roller with reliable guidance . The support can also take place in the opposite way from the support lever with the same effect.

Γη der Zeichnung ist eine Ausführungsform zur Darstellung gebracht. Der Hebelarm a der Druckrolle e ist durch den Traghebel /* mit dem Scharträger b vertikal ausschwingbar verbunden. Der Hebelarm α trägt den Stützhebel d, der sich in verschiedenen Stellungen mit einem Schlitz oder in ähnlicher Weise in einem Bolzen des Traghebels/ abstützt. Zur Ausgleichung von Stoßen usw. kann die Abstützung federnd erfolgen.An embodiment is shown in the drawing. The lever arm a of the pressure roller e is connected to the coulter carrier b by the support lever / * so that it can swing out vertically. The lever arm α carries the support lever d, which is supported in various positions with a slot or in a similar manner in a bolt of the support lever /. To compensate for bumps, etc., the support can be resilient.

Beim Ausheben der Drillschare und bei Bodenunebenheiten schwingt die Druckrolle, wie strichpunktiert dargestellt, aus.When the seed coulters are lifted out and on uneven ground, the pressure roller swings, as shown in dash-dotted lines.
