Eine derartige Vorrichtung ist aus der EP-PS 01 08 196 bekannt. Diese bekannte Vorrichtung hat einen auf der Oberfläche des eingelagerten Schüttguts bewegbaren Förderer in Form von Förderschnecken zum Fördern von oberflächig abgekratztem oder abgeschältem Schüttgut zu einer im Siloboden vorgesehenen Austragsöffnung. Das Schüttgut wird dabei durch Öffnungen in der Wand eines zentralen Dorns durch dessen Hohlraum zur unteren Austragsöffnung gefördert.Such a device is from EP-PS 01 08 196 known. This known device has one on the Movable conveyor surface of the stored bulk goods in the form of screw conveyors to convey surface scraped or peeled bulk goods into an im Discharge opening provided in the silo floor. The bulk material will thereby through openings in the wall of a central mandrel through its cavity to the lower discharge opening promoted.

Diese bekannte Austragsvorrichtung hat den Nachteil, daß das Austragen von Schüttgut ungleichmäßig verläuft, weil die Öffnungen im zentralen Dorn nur abschnittsweise vorgesehen sind. Außerdem kann das Schüttgut durch Brückenbildung die Öffnungen verstopfen. Allein durch die Bewegung der Förderschnecke werden die Austragsöffnungen dann nicht frei. An der bekannten Vorrichtung ist ferner nachteilig, daß die untere Austragsöffnung im zentralen Dorn nicht oder schlecht zugänglich ist, so daß bei einer Verstopfung ein Freimachen der Austragsöffnung nicht möglich ist oder erschwert wird.This known discharge device has the disadvantage that the Discharge of bulk material is uneven because the Openings in the central mandrel are only provided in sections are. In addition, the bulk material can form the bridges Block openings. Just by moving the The screw conveyor will then not clear the discharge openings. Another disadvantage of the known device is that  that the lower discharge opening in the central mandrel is not or is difficult to access, causing constipation it is not possible to clear the discharge opening or is difficult.

Der Erfindung liegt die Aufgabe zugrunde, eine Schüttgutaustragsvorrichtung zu schaffen, mit der auf einfache Weise ein sicheres und störungsfreies gut dosierbares Austragen von Schüttgut aus einem Silo möglich ist.The invention has for its object a Bulk discharge device to create with the simple way a safe and trouble-free good Dosable discharge of bulk goods from a silo possible is.

Zur Lösung dieser Aufgabe wird bei der eingangs geschilderten Vorrichtung erfindungsgemäß vorgeschlagen, daß das Mittel zum Ausfördern von Schüttgut aus dem Silo ein Saugrohr ist, das mit seiner im Bereich der Förderschnecke endenden Saugöffnung höhenverstellbar ist und mit seiner entgegengesetzten Öffnung an die Saugseite einer Förderpumpe angeschlossen ist. Dabei kann bevorzugt das Saugrohr einen teleskopierbaren Saugrüssel aufweisen, dessen Ende am Auslegerarm für die Förderschnecke befestigt ist.To solve this problem at the beginning proposed device proposed according to the invention, that the means for conveying bulk material out of the silo is an intake manifold with its in the range of Screw conveyor ending suction opening is adjustable in height and with its opposite opening on the suction side a feed pump is connected. It can be preferred the suction tube has a telescopic proboscis, the end of which is attached to the cantilever arm for the screw conveyor is.

Die erfindungsgemäße Schüttgutaustragsvorrichtung ermöglicht im Gegensatz zu der bekannten ein einwandfreies störungsarmes Austragen von Schüttgut aus einem Silo, weil sie oberhalb der Schüttgutoberfläche angeordnet und daher jederzeit gut zugänglich ist. Der Austrag kann kontinuierlich und gut dosierbar durch Einstellen der Saugkraft der Förderpumpe geregelt werden. Das Saugrohr, das auch schlauchförmig sein kann, wird zweckmäßigerweise am Auslagerarm befestigt, an dem die Förderschnecke drehbar gelagert ist. Es läßt sich mit dem Auslegerarm um den zentralen Dorn drehen sowie längs desselben heben und senken. The bulk material discharge device according to the invention in contrast to the known one, allows a flawless smooth discharge of bulk goods from a silo because they are arranged above the bulk material surface and therefore is easily accessible at all times. The discharge can continuous and easy to dose by adjusting the Suction power of the feed pump can be regulated. The intake manifold, which can also be tubular, is conveniently on Outrigger arm attached to which the screw conveyor rotates is stored. It can be extended with the cantilever arm turn the central mandrel and lift along it and reduce.  

Bei Anordnung eines Schlauches zum Absaugen des Schüttguts, welches die Förderschnecke laufend von der Schüttgutoberfläche abkratzt und zur Ansaugöffnung des Saugschlauches fördert, muß eine entsprechende Anzahl von Schlingen des Schlauches angeordnet sein, damit dessen Ansaugöffnung bis zum Boden des Silos reichen kann. Wenn ein teleskopierbares Saugrohr verwendet wird, werden dessen Schüsse mit dem Auslegerarm bewegt.If a hose is arranged to extract the bulk material, which keeps the screw moving from the Scrapes the surface of the bulk material and to the suction opening of the Suction hose promotes a corresponding number of Loops of the hose can be arranged so that Intake opening can extend to the bottom of the silo. If A telescopic suction pipe is used Shots with the cantilever arm moves.

In der Zeichnung ist die erfindungsgemäße Austragsvorrichtung für Schüttgut aus einem Silo schematisch im Längsschnitt dargestellt.In the drawing is the invention Discharge device for bulk goods from a silo shown schematically in longitudinal section.

Im Silo 1 sind die Eintragsöffnung 2 für Schüttgut 3 der zentrale Dorn 4 ein um den Dorn drehbarer sowie in seiner Längsrichtung heb- und senkbarer Auslegerarm 5 angeordnet, an dem die Förderschnecke 6 um eine horizontale Achse drehbar gelagert ist. Am Auslegerarm 5 ist ferner das teleskopierbare Saugrohr 7 befestigt, dessen Ansaugöffnung im Bereich der Förderschnecke 6 liegt, die bei ihrer Drehung Schüttgut zu dieser Ansaugöffnung des Saugrohrs 7 fördert. Die Saugwirkung im Saugrohr wird durch eine Pumpe P erzeugt, die innerhalb oder außerhalb des Silos in das Saugrohr eingeschaltet ist.In the silo 1 , the entry opening 2 for bulk material 3, the central mandrel 4 and a boom arm 5 which is rotatable about the mandrel and can be raised and lowered in its longitudinal direction are arranged, on which the screw conveyor 6 is rotatably mounted about a horizontal axis. Also attached to the extension arm 5 is the telescopic suction pipe 7 , the suction opening of which lies in the area of the screw conveyor 6 which, when it rotates, conveys bulk material to this suction opening of the suction pipe 7 . The suction effect in the suction pipe is generated by a pump P, which is switched on inside or outside the silo in the suction pipe.
