Description

Bisher bekannte Konstruktionen von Vibrationstischen haben verschiedene Nachteile. Oft erfolgt die Schwingung des Trägers für das Schüttelgut in einer Ebene; so däß während des Schüttelvorganges keine genügende Durchmischung des Gutes stattfindet. Andererseits werden durch Rückwirkung des Schüttelimpulses die Antriebsmaschine und der Unterbau ebenfalls in Schwingungen versetzt, die sich schädlich auswirken.Previously known designs of vibrating tables have various Disadvantage. Often the vibration of the carrier for the material to be shaken occurs in one plane; so that there is insufficient mixing of the material during the shaking process. On the other hand, through the reaction of the shaking impulse, the driving machine becomes and the substructure also vibrates, which has a harmful effect.

Die Erfindung behebt diese Nachteile und betrifft einen Vibrationstisch,welcher in der Beschreibung und Zeichnung beispielsweise erläutert ist.The invention overcomes these disadvantages and relates to a vibrating table which is explained in the description and drawing, for example.

Eine kreisförmige Platte 3; welche auf dem Gehäuse eines Antriebsmotors des Vibrationstisches angebracht ist, trägt acht -Schraubenfedern 8 oder sonstige elastische Körper, wie Gummi, die in der Tragplatte 7 befestigt sind. Die von dem Antriebsmotor ausgehende Welle i ruht in den Kugellagern 2 und versetzt bei Drehung mit Hilfe des exzentrisch eingesetzten Bolzens 6 die Tragplatte 7 in schwingende Bewegung. Der Bolzen 6 ist in einem Pendelkugellagers der Tragplatte? gelagert. Entgegengesetzt zur Exzentrizität des Bolzens 6 ist um i8o° versetzt auf der Welle i ein Ausgleichgewicht :I befestigt, das den waagerechten Schüttelimpuls der Platte 7 einschließlich des aufgesetzten Nutzgewichtes auf denUnterbau unwirksam macht. Die Schraubenfedern 8 schwingen in zwei Richtungen. Das Ende 9 bewegt sich einmal auf einem Kreis um die Achse der Schraubenfeder, zweitens schwingt die Schraubenfeder in Richtung ihrer Achse. Damit die beiden Schwingungen ungestört vor sich gehen können, ist das Kugellager 5 als Pendellager ausgebildet. Auf jeden Punkt innerhalb des Schüttelgutes erfolgt ein Impuls, dessen eine Komponente waagerecht und die andere senkrecht liegt. Hierdurch erfolgt eine starke Durchmischung, so däß bei einem Siebvorgang ein inniger Austausch der verschiedenen Körnungen des Schüttelgutes stattfindet. Der Siebeffekt besteht also so lange, bis die kleinste Körnung entsprechend der Lochgröße des Siebes abgesiebt ist.A circular plate 3; which on the housing of a drive motor of the vibration table is attached, carries eight coil springs 8 or other elastic bodies, such as rubber, which are fixed in the support plate 7. The one from that Drive motor outgoing shaft i rests in ball bearings 2 and is offset when rotating with the help of the eccentrically inserted bolt 6, the support plate 7 in swinging Move. The bolt 6 is in a self-aligning ball bearing of the support plate? stored. Opposite to the eccentricity of the bolt 6 is offset by 180 ° on the shaft i a balance weight: i attached, which the horizontal shaking impulse of the plate 7 including the useful weight placed on the substructure ineffective. The coil springs 8 swing in two directions. The end 9 moves once on a circle around the axis of the helical spring, second, the helical spring swings in the direction of its axis. So that the two vibrations go on undisturbed can, the ball bearing 5 is designed as a self-aligning bearing. At every point within of the material being shaken there is an impulse, one component of which is horizontal and the other is perpendicular. This results in a strong mixing, so that at a sieving process, an intimate exchange of the different grain sizes of the material being shaken takes place. The sieving effect is so long until the smallest grain size accordingly the hole size of the sieve is sieved.

Wird auf den Z'ibrationstisch eine Kugelmühle aufgesetzt, so erfolgt ebenfalls eine innige Durchmischung des Schüttelgutes.If a ball mill is placed on the vibrating table, this takes place also an intimate mixing of the material to be shaken.
