Description

umlaufenden Siebradrotating sieve wheel

Die Erfindung bezieht sich auf eine Siebvorrichtung an Kartoffelerntemaschinen, bei der ein Siebrad mit einer darüberliegenden spiralförmigen Leitwand zusammenarbeitet. Bei dieser bekannten Einrichtung gelangt der Kartoffeldamm auf ein um eine senkrechte Achse umlaufendes Siebrad' und wird auf seiner Siebfläche durch die spiralig verlaufende feste Leitwand nach außen abgeführt. Der Nachteil bei dieser Ausführung liegt darin, daß die fester anhaftenden Erdreste hauptsächlich bei feuchten Lehmböden durch das Rollen über die Siebfläche nicht beseitigt werden, sondern, da sie auf dieser frei aufliegen, sich noch fester anlegen: Da die meisten Kartoffeln eine unregelmäßige Form haben, rollen diese nicht ohne weiteres über die Scheibe, sondern werden in der ursprünglichen Lage über die Scheibe geschoben, und daher nur einseitig gereinigt.The invention relates to a sieve device on potato harvesters which cooperates a sieve wheel with an overlying spiral guide wall. In this known device, the potato dam reaches a vertical one Axis revolving sieve wheel 'and is on its sieve surface by the spiral fixed baffle led to the outside. The disadvantage of this design lies in the fact that the more firmly adhering earth remains mainly in moist loamy soils are not eliminated by rolling over the screen surface, but because they are on this lie freely, lay down even more tightly: Since most potatoes have an irregular shape Shape, they don't just roll over the pane, but are in the original position pushed over the pane, and therefore only cleaned on one side.

Die Erfindung besteht nun darin, daß dasThe invention consists in that the

mit der Leitwand fest verbundene Siebrad nachgiebig oder federnd gegenüber .einer darüberliegenden feststehenden, ringartigen Deckscheibe gelagert ist. Durch diese Einrichtung werden die Kartoffeln gegen die Siebfläche gedrückt und dadurch zum Rollen gezwungen, so daß eine restlose Reinigung der Kartoffeln bei schonendster Behandlung sichergestellt ist. Eine weitere zweckmäßige Ausbildung der Erfindung besteht darin, daß die Siebfläche des Siebrades aus radiale Schlitze frei lassenden, nach unten nachgiebigen Giimmistegen besteht, die auch in die Unebenheiten der Kartoffeln eingreifen können und eine schonende Behandlung der Kartoffeln sicherstellen.with the baffle firmly connected sieve wheel yielding or resilient opposite .einer overlying fixed, ring-like cover disk is mounted. Through this facility the potatoes are pressed against the sieve surface, causing them to roll forced, so that a complete cleaning of the potatoes with the most gentle treatment is ensured. Another useful embodiment of the invention is that leaving the sieve surface of the sieve wheel free from radial slots, yielding downwards Giimmistegen exists, which also intervene in the unevenness of the potatoes and ensure that the potatoes are treated gently.

Der Gegenstand der Erfindung ist auf der Zeichnung dargestellt, und zwar zeigt Abb. 1 die Siebvorrichtung von der Seite gesehen im Schnitt und Abb. 2 dieselbe in der Draufsicht bei abgenommener Deckscbeibe.The object of the invention is shown in the drawing, namely Fig. 1 the sieve device seen from the side in section and Fig. 2 the same in plan view with the deck window removed.

Die Vorrichtung gemäß der Erfindung besteht aus einem Siebrad 2 und einer fest mit ihm Verbundenen spiraligen Leitwand 3. Der Boden des Siebrades weist radiale Schlitze auf, zwischen denen kantige, nach unten nachgiebige Gummistege 5 liegen. Das Siebrad ist gegenüber einer darüber fest angebrachten Deckscheibe 1 federnd gelagert. Die Feder ist mit 4 bezeichnet.The device according to the invention consists of a sieve wheel 2 and one fixed to it Spiral baffle 3 connected to it. The bottom of the sieve wheel has radial slots on, between which angular, downwardly resilient rubber webs 5 are. The sieve wheel is with respect to a cover plate 1 firmly attached above it, is resiliently mounted. The feather is denoted by 4.
