Abstract

A rotating brush (1) assembly separates potatoes (2) from stones and earth by acceleration in which the brush (7) only transmits kinetic energy to the potatoes. The brush bristles are much longer than prior art.

Description

Trennvorrichtungen zum Trennen von Steinen und Kartoffeln werden in der Landwirtschaft auf Erntemaschinen, in Einlagerungseinrichtungen und in Kartoffelaufbereitungsanlagen eingesetzt.separators for separating stones and potatoes are used in agriculture on harvesting machines, in storage facilities and in potato processing plants used.

Die üblichen Trennvorrichtungen mittels Bürsten, Gummifingerbändern ( DE 20206240 U1 ) oder Stahlwalzen ( DE 3306769 C2 ) erzielen ein unbefriedigendes Ergebnis und erfordern demzufolge eine Nachsortierung von Hand.The usual separation devices using brushes, rubber finger bands ( DE 20206240 U1 ) or steel rollers ( DE 3306769 C2 ) achieve an unsatisfactory result and therefore require re-sorting by hand.

Elektronische Systeme ( DE 4317513 A1 ) arbeiten zufrieden stellend, sind aber sehr teuer und wartungsintensiv.Electronic systems ( DE 4317513 A1 ) work satisfactorily, but are very expensive and maintenance-intensive.

Weiterhin sind Trennvorrichtungen bekannt die mit Wasser arbeiten ( DE 4434650 C1 ), was aber eine Verringerung der Lagerfähigkeit zur Folge hat.Furthermore, separation devices are known which work with water ( DE 4434650 C1 ), which results in a reduction in shelf life.

Des Weiteren gibt es Trennvorrichtungen die mit einem starken Luftstrom die Kartoffeln von den Steinen trennen ( DE 69228425 T2 ), wobei aber ein sehr hoher Energiebedarf zu verzeichnen ist.There are also separators that separate the potatoes from the stones with a strong air stream ( DE 69228425 T2 ), but there is a very high energy requirement.

Der Erfindung liegt die Aufgabe zugrunde, eine Trennvorrichtung, die kostengünstig, hochwirksam und zuverlässig ist, zu schaffen.The The invention has for its object a separation device that cost-effective, highly effective and reliable is to create.

Die Erfindung löst die Aufgabe durch eine Trennvorrichtung, bei der die zu trennenden Gegenstände 2 (Steine und Kartoffeln) durch eine Umlaufende Bürstenwalze 1 voneinander getrennt werden.The invention solves the problem by a separating device in which the objects to be separated 2 (Stones and potatoes) by a rotating brush roller 1 be separated from each other.

Die Neuerung besteht darin das die Borsten 7 der Bürstenwalze 1 sehr lang sind, wodurch ein Zustand geschaffen wird, der einem Volumenstrom ähnlich, auf den zu trennenden Gegenstand 2 einwirkt.The innovation is that the bristles 7 the brush roller 1 are very long, creating a state similar to a volume flow on the object to be separated 2 acts.

Durch die Drehbewegung der Bürste 1 treffen die Borsten 7 auf den zu trennenden Gegenstand 2 und beschleunigen den Gegenstand 2, indem die kinetische Energie der auftreffenden Borsten 7 auf den Gegenstand 2 überragen wird.By rotating the brush 1 hit the bristles 7 on the object to be separated 2 and accelerate the object 2 by the kinetic energy of the striking bristles 7 on the object 2 is towering over.

Durch das unterschiedliche spezifische Gewicht von Steinen und Kartoffeln werden Kartoffeln stärker beschleunigt als Steine.By the different specific weight of stones and potatoes potatoes get stronger accelerates as stones.

Diese unterschiedliche Beschleunigung kann zum Trennen von Steinen und Kartoffeln ausgenutzt werden, und erzielt im vergleich zum Stand der Technik eine wesentlich höhere Trenngenauigkeit bzw. verursacht wesentlich geringere Kosten.This different acceleration can be used to separate stones and Potatoes are used, and achieved compared to the state technology a much higher one Separation accuracy or causes significantly lower costs.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1 erläutert.An embodiment of the invention is based on the 1 explained.

Die Bürstenwalze 1 dreht sich mit einer entsprechenden Drehzahl bei der die Borsten 7 durch die Fliehkraft aufgerichtet werden.The brush roller 1 rotates at an appropriate speed at which the bristles 7 be erected by centrifugal force.

Der zu trennende Gegenstand 2 hat eine Flugbahn, die den Randbereich der Bürstenwalze berührt.The object to be separated 2 has a trajectory that touches the edge of the brush roller.

Der zu trennende Gegenstand 2, in diesem Fall eine Kartoffel, wird stark abgebremst und erreicht die Flugbahn 3.The object to be separated 2 , in this case a potato, is braked sharply and reaches the trajectory 3 ,

Der zu trennende Gegenstand 2, in diesem Fall ein Stein, verringert seine Geschwindigkeit nicht so stark, weil er ein größeres spezifisches Gewicht hat, und erreicht die Flugbahn 4.The object to be separated 2 In this case, a stone does not decrease its speed as much because it has a larger specific weight and reaches the trajectory 4 ,

Durch die Trennkante 5 werden Steine und Kartoffeln voneinander getrennt weggeführt.Through the separating edge 5 stones and potatoes are removed separately.

Ein weiteres Ausführungsbeispiel der Erfindung wird anhand der 2 erläutert.Another embodiment of the invention is based on the 2 explained.

Der zu trennende Gegenstand 2 wird auf einem Gurtband 6 zur Bürstenwalze 1 geführt.The object to be separated 2 is on a webbing 6 to the brush roller 1 guided.

Ein Stein wird durch die Bürstenwalze 1 kaum beschleunigt und erreicht die Flugbahn 4.A stone is hardly accelerated by the brush roller 1 and reaches the trajectory 4 ,

Eine Kartoffel wird stärker beschleunigt und erreicht die Flugbahn 3.A potato is accelerated faster and reaches the trajectory 3 ,

Durch die Trennkante 5 werden Steine und Kartoffeln voneinander getrennt weggeführt.Through the separating edge 5 stones and potatoes are removed separately.
