Description
Gegenstand der Erfindung ist ein einfaches Verfahren zum Sichten von Baum-, Feld- und Bodenfrüchten, z. B. Kartoffeln oder Äpfeln, zur Aus-Scheidung -der verdorbenen Früchte. Das Verfahren besteht -darin, daß .die guten und die verdorbenen Früchte auf Grund ihrer unterschiedlichen Elastizität voneinander getrennt wenden. Insbesondere kann das Verfahren derart -durchgeführt wenden, daß .die Sichtung auf Grund des von der Elastizität abhängigen unterschiedlichen Rückprallwinkels der gegen eine hochelastische Fläche gegenprallenden Früchte erfolgt. An Hand einer in der Zeichnung dargestellten vorteilhaften Anordnung zur Sichtung von Kartoffeln wird das Verfahren nach der Erfindung noch näher erläutert.The invention relates to a simple method for sifting through Tree, field and ground crops, e.g. B. potatoes or apples, for separation -of the rotten fruit. The procedure consists in that the good and the bad Turn fruits separately due to their different elasticity. In particular, the method can be carried out in such a way that the sighting takes place Reason for the different rebound angle depending on the elasticity of the fruit bouncing against a highly elastic surface. On the hand of one Advantageous arrangement shown in the drawing for the sifting of potatoes the method according to the invention is explained in more detail.
Die Kartoffeln rutschen auf einer Schurre i herab und fallen gegen eine Platte 2 aus Stahl oder einem anderen hochelastischen Stoff, die an der Wand 3 befestigt ist. Unterhalb der Prellstelle der Platte ist eine Scheidewand 4 derart angeordnet, daß die von der Platte 3 auf Grund ihrer Elastizität zurückprallenden Kartoffeln in der Regel auf der linken Seite der Scheidewand niederfallen. Die faulen oder anderweitig verdorbenen und weichen Kartoffeln dagegen, die weniger elastisch sind und .daher auch weniger zurückprallen, fallen auf der rechten Seite der Scheidewand nieder und werden auf diese Weise von den guten Kartoffeln abgesondert.The potatoes slide down on a chute and fall against it a plate 2 made of steel or some other highly elastic material attached to the wall 3 is attached. Below the bounce point of the plate is a partition 4 of this type arranged that the rebounding from the plate 3 due to their elasticity Potatoes usually fall down on the left side of the septum. The lazy ones or otherwise rotten and soft potatoes on the other hand, the less elastic are and .therefore less rebounding, fall on the right side of the septum and are thus set apart from the good potatoes.
Das Verfahren nach der Erfindung ist nicht an die in der Zeichnung dargestellte Anordnung gebunden, sondern kann auch mit anderen geeigneten Anordnungen durchgeführt werden. Statt einer einzigen Schurre i können beispielsweise mehrere Schurren nebeneinander angeordnet -werden, so daß größere Mengen zugleich gesichtet werden können.The method according to the invention is not similar to that in the drawing The arrangement shown is bound, but can also be used with other suitable arrangements be performed. Instead of a single chute i, for example, several Chutes are arranged side by side so that larger quantities can be seen at the same time can be.
Von der Größe der Kartoffeln ist der Rückprallwinkel im wesentlichen unabhängig. Kleinere Unterschiede im Rückprallwinkel treten infolge der verschiedenen Form -der Kartoffeln auf; die Scheidewand 4 kann jedoch so aufgestellt werden, daß trotz einer gewissen Streuung alle guten Kartoffeln auf der einen und alle faulen auf der anderen Seite der Scheidewand niederfallen. Gegebenenfalls können, wie es in Fig. 2 angedeutet ist, zwei oder mehrere Scheidewände 5 und 6 nebeneinander angeordnet werden, ,so daß die guten Kartoffeln links von der Scheidewand 5, die schlechten rechts von der Scheidewand 6 und die mehr oder minder zweifelhaften zwischen Iden beiden Scheidewänden 5 und 6 niederfallen. Vorteilhaft können die Scheidewände auch verstellbar vorgesehen -wenden.The rebound angle is essentially the size of the potatoes independent. Minor differences in rebound angle occur as a result of the different Form -of potatoes on; however, the partition 4 can be set up so that despite a certain spread, all good potatoes on the one hand and all rotten fall down on the other side of the septum. If necessary, like it is indicated in Fig. 2, two or more partitions 5 and 6 arranged side by side be, so that the good potatoes left by the septum 5, the bad to the right of the partition 6 and the more or less doubtful between ides both partitions 5 and 6 fall down. The partitions can also be advantageous adjustable provided -turn.
