Description
Gegenstand der Erfindung ist eine Druckrolle mit selbsttätiger Regelung der Saattiefe. Druckrollen an Drillmaschinen und ihre günstige Wirkung auf die Saat sind bereits in verschiedenen Ausführungsformen bekannt. Diese Druckrollen haben aber sämtlich ein so hohes Eigengewicht, daß sie für schweren, lehmigen Boden einer weiteren Belastung nicht bedürfen, dagegen in leichten, sandigenThe invention relates to a pressure roller with automatic control of the sowing depth. Pressure rollers on seed drills and their beneficial effect on the seeds are already in place known in various embodiments. However, these pressure rollers all have one high dead weight that they are a further burden for heavy, loamy soil not necessary, but in light, sandy
ίο Boden viel zu tiefe Rillen eindrücken, die vom Winde leicht zugeweht werden und die Saat verschütten.ίο Press grooves that are far too deep into the ground be blown in slightly by the wind and spill the seeds.
Diesen bekannten Druckrollen gegenüber unterscheidet sich der Erfmdungsgegenstand durch eine ganz leichte Rolle — z. B. Holz mit Eisenbeschlag —, die in sandigen und milden Boden nur flache Rillen eindrückt und auf schwerer werdendem Acker je nach Bedarf durch verstellbare Gewichte bis zur gewünschten Wirkung belastet werden kann. Dadurch wird eine gleichmäßige Rillentiefe für die verschiedenen Bodenarten erreicht und ein Verwehen und Verschütten der jungen Saat verhindert. Derartige Gewichtsbelastungen an sich sind ebenfalls nicht unbekannt. The subject matter of the invention differs from these known pressure rollers through a very light role - e.g. B. Wood with iron fittings - which in sandy and only press shallow grooves in mild soil and on increasingly heavy fields as required can be loaded to the desired effect by means of adjustable weights. This creates a uniform groove depth for the different types of soil reached and a blowing and spilling of the young Prevented sowing. Such weight loads per se are also not unknown.
Bekanntlich dringen aber nicht nur die Druckrollen, sondern auch die Drillschare in sandigen Acker viel zu tief ein und bringen die Saat in eine ungedeihliche Bodenschicht, während die Körner in schweren, lehmigen Boden zu flach hineinkommen oder offen liegen bleiben.It is well known that not only the pressure rollers penetrate, but also the seed coulters sandy fields far too deep and bring the seeds into an unhealthy soil layer, while the grains come in too shallowly or remain open in heavy, loamy soil.
Zur Beseitigung dieses Übelstandes ist der Erfindungsgegenstand (Druckrolle) mit einem Hebelarm α derartig an dem Drillscharhebel b angebracht, daß ein unerwünschtes Ausschwingen des Drillschares c nach unten — besonders bei Sandboden — durch einen am Druckrollenhebelarm a verstellbaren Anschlag d verhindert wird.To eliminate this evil prior subject invention (pressure roller) with a lever arm is α such to the drill coulter lever b mounted so that an undesired decay of the drill coulter c downwards - d is prevented by the Druckrollenhebelarm a adjustable stop - especially in sandy soil.
Gleichzeitig wirkt aber auch die Druckrolle e selbst — je nach Einstellung ihrer Gewichtsbelastung/ — auf leichtem Boden' weniger und auf schwerem Boden stärker belastend (herunterziehend) auf den Drillscharhebel b. Durch diese Doppelwirkung wird nicht nur das Drillschar c an einem zu tiefen Eindringen in sandigen Boden verhindert, sondern auch zu tieferem Eindringen in lehmigen Boden gezwungen, bis durch den Anschlag d an den Drillscharhebel b die richtige Saattiefe geregelt ist.At the same time, however, the pressure roller e itself - depending on the setting of its weight load / - has less of an impact on light soil and more stressful on heavy soil (pulling it down) on the coulter lever b. This double action not only prevents the coulter c from penetrating too deeply into sandy soil, but also forces it to penetrate deeper into loamy soil until the correct sowing depth is regulated by the stop d on the coulter lever b.
In der Zeichnung ist eine Ausführungsform zur Darstellung gebracht.In the drawing, an embodiment is shown.
Die Druckrolle e ist durch den Hebelarm a vertikal drehbar mit dem Dnllscharhebel b verbunden. Der Druckrollenhebelarm α trägt an seinem freien (oberen) Ende einen verstellbaren Anschlaghebel d, der ein Ausschwingen des Drillschars c — nach unten — durch Anschlag an den Drillscharhebel b be- · grenzt, während das Gewicht der Druckrolle selbst ein Ausschwingen ·— nach oben — oder Abgleiten vom Boden verhindert.The pressure roller e is vertically rotatably connected to the coulter lever b by the lever arm a . The pressure roller lever arm α carries at its free (upper) end an adjustable stop lever d which limits the swinging out of the drill coulter c - downwards - by stopping at the drill coulter lever b , while the weight of the pressure roller itself swings out - upwards - or sliding off the ground.
Der Druckrollenhebel α ist verlängert durch den Hebelarm g. Dieser trägt verstellbare Gewichte f, die je nach ihrer Einstellung durch Hebelwirkung die Belastung der Druckrolle e steigern oder verringern.The pressure roller lever α is extended by the lever arm g. This carries adjustable weights f which, depending on their setting, increase or decrease the load on the pressure roller e through leverage.
