KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bekannt sind Sägehäuse mit federndem und zwecks Entleerung aufklappbarem Boden, dessen Federung durch eine Flachfeder bewerkstelligt wird in der Weise, daß sich dieselbe auf einen festen Knaggen des Sägehäuses stützt und der Sägehäuseboden einerseits bei der Arbeit nach der Särolle zu angedrückt wird und anderseits bei der Entleerung des Gehäuses, also beim Niederklappen des Sägehäusebodens, in dieser Stellung festgehalten wird.Sowing housings with a resilient floor that can be opened for emptying are known, whose suspension is brought about by a flat spring in such a way that the same rests on a fixed lug of the seed housing and the seed housing bottom on the one hand when working after the Särolle is pressed and on the other hand when emptying the Housing, so when folding down the seed housing bottom, held in this position will.

Die bekannten Nachteile, welche eine Flachfeder aufweist, zumal wenn sie größere Beanspruchung erleidet, gaben Veranlassung zu vorliegender Erfindung, gemäß welcher die Flachfeder durch eine an sich bekannte Schraubenfeder ersetzt ist. An Stelle der Flachfeder wurde eine Druckplatte vorgesehen, die unter dem Druck der Schraubenfeder steht.The known disadvantages that a flat spring has, especially when it is subject to greater stress suffered, gave rise to the present invention, according to which the flat spring by a known helical spring is replaced. Instead of the flat spring, a pressure plate was provided, which under is under the pressure of the coil spring.

Zur näheren Erläuterung dient die Zeichnung. In dieser bedeutet α das Sägehäuse einer beliebigen Sämaschine, b den in Arbeitsstellung befindlichen Boden ; δ1 stellt denselben in punktierten Linien in Entleerungsstellung dar. c zeigt eine starre Druckplatte, auf welche die Schraubenfeder d durch einen mit Gewinde versehenen Federbolzen β mit Schraubenmutter f nachstellbar einwirkt.The drawing is used for a more detailed explanation. In this, α means the sowing housing of any seed drill, b the soil in the working position; δ 1 represents the same in dotted lines in the emptying position. c shows a rigid pressure plate on which the helical spring d acts in an adjustable manner by means of a threaded spring bolt β with a screw nut f.

Die Druckplatte c ruht einerseits auf dem Sägehäuseboden b, anderseits auf dem geeig-The pressure plate c rests on the one hand on the seed housing base b, on the other hand on the suitable

Claims (1)

Patent- Anspruch:Patent claim: net geformten Nocken g. h bedeutet die Särolle. Die unter dem Federdruck der Schraubenfeder d stehende Platte e bewirkt genau dasselbe, was früher eine am Sägehäuseboden b angeschraubte Flachfeder von ähnlicher Form wie Druckplatte c bewirkte. Wird nun der Boden herabgedrückt, so verschiebt sich die Druckplatte c und legt sich hinter den Nokken g, wodurch der Boden in der Entleerungsstellung gehalten wird. Durch diese Neuerung sind alle Nachteile der bekannten Konstruktionen beseitigt, wie leichtes Brechen der Flachfeder, unbequemes Auswechseln der dabei zu spannenden Feder, keine Nachstellbarkeit beim Nachlassen der Federkraft usw.net shaped cam g. h means the Särolle. The plate e , which is under the spring pressure of the helical spring d , has exactly the same effect as what a flat spring screwed to the seed housing base b earlier, of a similar shape to the pressure plate c, did. If the bottom is now pressed down, the pressure plate c shifts and lies behind the cam g, whereby the bottom is held in the emptying position. This innovation eliminates all disadvantages of the known constructions, such as easy breaking of the flat spring, inconvenient replacement of the spring to be tensioned, no readjustment when the spring force slackens, etc.
