Description

Die Erfindung bezieht sich auf Siebkettenroder. Um bei derartigen Rodern die Siebwirkung zu erhöhen, wird im allgemeinen die Umlaufgeschwindigkeit der Siebkette vergrößert. Dies erfordert aber einen erhöhten Kraftaufwand. Ferner werden durch Erhöhung der Umlaufgeschwindigkeit der Siebketten auch die übrigen mit dem Kettenantrieb verbundenen Einrichtungen der Maschine beschleunigt, was unter Umständen zur Beschädigung des Erntegutes und zu unbefriedigender Arbeit der Maschine und erhöhtem Verschleiß führt.The invention relates to chain sieve harvesters. In order to increase the sieving effect in such harvesters, the speed of rotation of the sieve chain is generally increased. This requires but an increased effort. Furthermore, by increasing the rotational speed of the Sieve chains also accelerate the other devices of the machine connected to the chain drive, which can lead to damage to the crop and unsatisfactory operation of the machine and increased wear and tear.

Gemäß der Erfindung wird die Siebwirkung der Kette unter Beibehaltung ihrer normalen Umlaufgeschwindigkeit dadurch verbessert, daß in der Siebkettenbahn eine nach hinten steil ansteigende Fläche gebildet wird, vor der sich der Kartoffeldamm staut und umgewälzt wird. Durch diesen Vorgang wird die Siebwirkung erheblich gesteigert, ohne daß hierfür ein wesentlich höherer Kraftaufwand erforderlich wäre. Die starke Neigung eines Teiles der Siebkette wird .dadurch erzielt, daß durch Anordnung von Stützrollen in der gelockerten Siebkette eine Mulde gebildet wird. Die Stützrollen können zu diesem Zweck in der Höhe verstellbarAccording to the invention, the sieving effect of the chain while maintaining its normal speed of rotation improved by the fact that in the sieve chain path a steeply rising rearward Area is formed in front of which the potato dam accumulates and is turned over. Through this Process, the sieving effect is increased considerably without the need for a significantly higher expenditure of force would be required. The strong inclination of part of the sieve chain is achieved by the fact that Arrangement of support rollers in the loosened sieve chain a trough is formed. The support rollers can be adjusted in height for this purpose

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar in Seitenansicht und Grundriß. Die Siebkette I, die in bekannter Weise über Umlenk- und Stützrollen geführt ist, wird durch ein weiteres, durch Hand in der Höhe verstellbares Stützrollenpaar hochgehoben, so daß eine Mulde entsteht, an deren steil aufsteigender Wandung der Kartoffeldamm zurückfällt und umgewälzt wird. Hierdurch ist eine erhöhte Siebwirkung erzielbar.In the drawing, an embodiment of the invention is shown, in side view and floor plan. The sieve chain I, which is guided in a known manner over deflection and support rollers, is lifted up by a further pair of support rollers that can be adjusted in height by hand, so that a hollow is created, on the steeply rising wall of which the potato dam falls back and is turned over will. In this way, an increased screening effect can be achieved.
