Getreideputz- und Sortiermaschine. Patentiert im Deutschen Reiche vom 29. Juni 1923 ab. Grain cleaning and sorting machine. Patented in the German Empire on June 29, 1923.

Es sind bereits Getreideputz- und Sortiermaschinen bekannt, bei denen das pendelnd aufgehängte Sieb durch umlaufende, exzentrisch gelagerte Gewichte in schwingende oder S in geschlossener Kurve pendelnde Bewegung versetzt wird, deren Amplituden jedoch stets symmetrisch zu der durch die lotrechte Lage der Hauptstangen gegebenen Achse sind, so daß das durchzusichtende Getreide o. dgl. nur herumgeworfen wird, in keiner Richtung jedoch einen Vorschub erhält.Grain cleaning and sorting machines are already known in which the commuting suspended sieve by rotating, eccentrically mounted weights in vibrating or S pendulum motion is set in a closed curve, but its amplitudes always are symmetrical to the axis given by the perpendicular position of the main rods, see above that the grain or the like to be sifted through is only thrown around, in no direction however, receives a boost.

Es ist ferner auch bekannt, zwecks Mil-It is also known, for the purpose of mil-

derns von Stoßen Plansichter mit Federn zu versehen, die die Stöße auffangen, wobei jedoch die Schwingungsamplitüden des Siebkastens stets symmetrisch zur Lotrechten bleiben.rather than to provide plansifters with springs to absorb the impacts, however the vibration amplitudes of the sieve box are always symmetrical to the vertical stay.

Erfindungsgemäß wird an der Maschine zwischen Gestell und Siebkasten gegen den letzteren druckend eine Feder angeordnet, wodurch der Siebkasten in der Ruhelage ίο dauernd angehoben und gegenüber der Mittellage verschoben ist, infolgedessen er unsymmetrisch zur Lotrechten ausschwingt, so daß das Sichtgut durch die gleichzeitige Einwirkung der Verstellung und der frei pendelnden Aufhängung nicht nur in einer Richtung vorgeschoben, sondern gleichzeitig auch durchgeschüttet wird.According to the invention is on the machine between the frame and screen box against the the latter printing a spring arranged, whereby the screen box in the rest position ίο is constantly raised and shifted relative to the central position, as a result of which it is asymmetrical swings out to the perpendicular, so that the material to be viewed through the simultaneous action the adjustment and the freely oscillating suspension not only advanced in one direction, but also at the same time is poured through.

Auf der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung nach der Erfindung bo dargestellt, und zwar in Abb. 1 in Seitenansicht, in Abb. 2 in Stirnansicht.In the drawing is an embodiment of the device according to the invention bo shown, namely in Fig. 1 in side view, in Fig. 2 in front view.

Das Sieb 1 ist im Rahmen 2 mittels Hängestangen 3 frei pendelnd aufgehängt. Unten am Siebkasten sind quer zwei miteinander parallele Wellen 4 und S übereinander gelagert, die an einem Ende mit einem Paar miteinander in Eingriff stehender Zahnräder und außerdem an entgegengesetzten Enden mit exzentrischen Gewichten 8, 9 versehen sind, die in bekannter Weise derart zueinander eingestellt sind, daß die wagerechten Fliehkraftkomponenten addiert werden, die lotrechten dagegen sich gegenseitig aufheben, wodurch das Sieb in schwingende Bewegung versetzt wird. Der Antrieb der Exzenter erfolgt durch die auf der Welle 4 aufgesetzte Riemenscheibe 10.The sieve 1 is suspended freely oscillating in the frame 2 by means of hanging rods 3. At the bottom of the screen box, two parallel shafts 4 and S are transversely one above the other supported at one end with a pair of meshing gears and also provided with eccentric weights 8,9 at opposite ends are, which are set in a known manner to each other in such a way that the horizontal Centrifugal force components are added, the perpendicular, on the other hand, cancel each other out, causing the sieve to vibrate. The drive of the eccentric takes place by means of the belt pulley 10 placed on the shaft 4.

Erfindungsgemäß steht der Siebkasten 1 unter Einwirkung von am Rahmen 2 befestigten, zwischen Gestell und Siebkasten angeordneten Schraubenfedern 11, die auf seine Stirnseite parallel zu seiner Längsachse drücken und dadurch bewirken, daß der Siebkasten in der Ruhe in einer Lage verbleibt, in welcher die Hängestangen 3 einen Winkel mit der Lotrechten schließen, dessen Größe von der Stärke bzw. auch Länge und Stellung der Schraubenfedern 11 abhängt. Die Schraubenfedern 11 können selbstverständlich durch andere gleichwertige technische Mittel ersetzt werden.According to the invention, the screen box 1 is under the action of attached to the frame 2, between the frame and screen box arranged coil springs 11, which on his Press the end face parallel to its longitudinal axis and thereby cause the sieve box remains at rest in a position in which the hanging rods 3 close an angle with the perpendicular, its size on the strength or length and position of the coil springs 11 depends. the Coil springs 11 can of course be replaced by other equivalent technical Funds to be replaced.
