Es ist eine derartige Vorrichtung bekannt (DE-PS-2 263 549), bei der die Teile des Förderbandes an Rahmenteilen gehaltert sind, die um ein gemeinsames Traglager verschwenkbar sind, wobei ferner als Förderband ein Band verwendet wird, das an seinen Seiten hochstehende Ränder aufweist, oder als Wellkantengurt ausgebildet ist. Bei einer weiteren derartigen bekannten Vorrichtung (DE-PS-2542940) wird ein glattes Band als Förderband verwendet, das an den beiden Stirnkanten zwischen dichtanliegenden Gehäuseseitenteilen angeordnet ist. Das Wasser und die Verunreinigungen werden über einen unterhalb des Gehäuses angeordneten Trichter ausgetragen. Das gereinigte Grobgut wie Sand, Erz, Kohle Bauxit und dergleichen wird entgegen der Förderrichtung der Verunreinigungen aus dem Gehäuse heraustransportiert und verarbeitet. Dieses Grobgut ist mit einem geringen Wasseranteil versehen, so daß es meistens erforderlich ist, eine Nachentwässerung vorzunehmen, wozu besondere zusätzlich Entwässerungsapparate notwendig sind, die einen beachtlichen Aufwand und auch eine beachtliche Energie verursachen. Außerdem ergeben sich bei diesem Entwässerungsvorgang Verluste des ausgetragenen Gutes.Such a device is known (DE-PS-2 263 549), in which the parts of the conveyor belt are held on frame parts which can be pivoted about a common support bearing, and a belt is also used as the conveyor belt which has upstanding edges on its sides has, or is designed as a corrugated edge belt. In another such known device (DE-PS-2542940), a smooth belt is used as the conveyor belt, which is arranged on the two end edges between close-fitting housing side parts. The water and impurities are discharged through a funnel located below the housing. The cleaned coarse material such as sand, ore, coal bauxite and the like is transported out of the housing and processed against the direction in which the impurities are conveyed. This coarse material is provided with a small amount of water, so that it is usually necessary to carry out post-drainage, for which special additional drainage apparatuses are necessary, which cause considerable effort and energy. In addition, there are losses in the discharged material during this dewatering process.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend zu verbessern, daß eine Nachentwässerung des ausgetragenen gereinigten Grobgutes vermieden wird.The invention has for its object to improve a device of the type mentioned in that post-drainage of the discharged cleaned coarse material is avoided.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß im Bereich des unterhalb der Schurre verlaufenden ansteigenden Teiles des Förderbandes und außerhalb der Waschmulde ein oder mehrere Vibrationsverdichter angeordnet sind, wobei das Förderband von unten durch das Vibrationselement abgestützt ist.This object is achieved according to the invention in that one or more vibration compressors are arranged in the region of the rising part of the conveyor belt running below the chute and outside the washing trough, the conveyor belt being supported from below by the vibration element.

Vorteilhaft reicht das Vibrationselement über die ganze Breite des Förderbandes.The vibration element advantageously extends over the entire width of the conveyor belt.

Eine weitere vorteilhafte Ausführungsform sieht vor, daß das Vibrationselement vertikal zum Förderband und in Laufrichtung des Förderbandes verstellbar ist.Another advantageous embodiment provides that the vibration element is adjustable vertically to the conveyor belt and in the running direction of the conveyor belt.

Schließlich wird vorgeschlagen, daß die Erre-- gerfrequenz des Vibrationsverdichters verstellbar ist.Finally, it is proposed that the excitation frequency of the vibration compressor be adjustable.

Die Erfindung bringt den wesentlichen Vorteil, daß mit einfachen Maßnahmen eine vollständige Entwässerung des gereinigten Grobgutes erzielt werden kann, so daß eine Nachentwässerung unter Einsatz aufwendiger Einrichtungen vermieden wird. Für den Einsatz der Zusatzeinrichtung wird weiterhin nur eine geringe Energie gebraucht, wobei weiterhin der Verschleiß äußerst gering ist. Die Vorrichtung läßt sich auch mit einfachen Mitteln an die Besonderheiten der bekannten Vorrichtung, wie beispielsweise Neigung des Förderbandes, Andruck und dergleichen anpassen.The invention has the essential advantage that complete measures can be used to completely dewater the cleaned coarse material, so that subsequent dewatering is avoided using complex equipment. Only a small amount of energy is still required for the use of the additional device, and wear is still extremely low. The device can also be adapted with simple means to the special features of the known device, such as inclination of the conveyor belt, pressure and the like.

An den einzelnen Trägern 2, 26 sind Druck- bzw. Umlenkrollen gehaltert, um die ein Förderband 29 geführt ist. Für den eigentlichen Auswaschvorgang dient der obere Teil des Förderbandes 29, wobei ein abwärts der Schurre 12 angeordneter Teil 9 des Förderbandes 29 die eigentliche Waschmulde 30 bildet und ein weiterer Teil 11 des Förderbandes 29 unterhalb der Schurre 12 gegen die Fließrichtung des über die Schurre 12 aufgegebenen Materials ansteigend angeordnet ist. Die Form der Waschmulde 30 wird im wesentlichen gebildet durch die in der Mitte am Träger 2 angeordnete höhenverstellbare Druckrolle 18, die Rolle 6 sowie eine Stützrolle 17. Im Bereich des Teiles 9 des Förderbandes 29 ist dieses ganz außen über eine weitere Umlenkrolle 32 geführt, die gleichzeitig als Spannrolle dient, wobei zwischen den Rollen 6 und 32 ein waagerecht verlaufender Teil 33 des Förderbandes 29 vorgesehen ist. Der entgegengesetzte Teil 11 des Förderbandes 29 ist am obersten Punkt über eine Antriebsrolle 7 mit Antriebsmotor 34 geführt. wobei die Rolle 7 mit Hilfe von Unterlegplatten 35 höhenverstellbar ist. Unterhalb der Spannrolle 18 ist das Förderband über eine Umlenkrolle 31 geführt.The device shown in Figures 1 and 2 has a machine frame 1, which is composed of individual carriers 2, 26 which are provided with an inner lining to form a container 27 with an outlet funnel 28. On the individual carriers 2, 26, pressure or deflection rollers are held, around which a conveyor belt 29 is guided. The upper part of the conveyor belt 29 is used for the actual washing-out process, a part 9 of the conveyor belt 29 arranged downstream of the chute 12 forming the actual washing trough 30 and a further part 11 of the conveyor belt 29 below the chute 12 against the direction of flow of the chute 12 Material is arranged increasing. The shape of the washing trough 30 is essentially formed by the height-adjustable pressure roller 18 arranged in the center on the carrier 2, the roller 6 and a support roller 17. In the area of part 9 of the conveyor belt 29, this is guided on the outside via a further deflection roller 32 which also serves as a tensioning roller, a horizontally extending part 33 of the conveyor belt 29 being provided between the rollers 6 and 32. The opposite part 11 of the conveyor belt 29 is guided at the uppermost point via a drive roller 7 with a drive motor 34. wherein the roller 7 is adjustable in height with the aid of washers 35. Below the tensioning roller 18, the conveyor belt is guided over a deflection roller 31.

Im Bereich des ansteigenden Teiles 11 des Förderbandes 29 befindet sich außerhalb der Waschmulde 30 ein Vibrationsverdichter 40, der über die gesamte Breite des Förderbandes 29 reicht. Dieser Vibrationsverdichter 40 besitzt eine am Maschinengestell 1 der Vorrichtung angebrachte Verankerungsplatte 41, an der Schwingelemente 42 angebracht sind, die ihrerseits eine Andruckplatte 43 tragen. Die Schwingungen der Andruckplatte 43 werden durch einen mechanischen oder elektrischen Erreger 44 erzeugt.In the area of the rising part 11 of the conveyor belt 29, outside the washing trough 30, there is a vibration compressor 40 which extends over the entire width of the conveyor belt 29 enough. This vibration compressor 40 has an anchoring plate 41, which is attached to the machine frame 1 of the device and to which oscillating elements 42 are attached, which in turn carry a pressure plate 43. The vibrations of the pressure plate 43 are generated by a mechanical or electrical exciter 44.

Die Platte 43 liegt unter Druck an dem Förderbandteil 11 an, wobei verschiedene Möglichkeiten bestehen, um die Lage der Platte 43 und auch die Intensität des Vibrationsverdichters 40 zu verändern. So können beispielsweise an der Verankerungsplatte 41 Schlitze 45 vorgesehen sein, so daß die Neigung der Platte 43, der Abstand zum Förderbandteil 11 und auch die Höhenlage, das heißt der Abstand zur Waschmulde 30 verändert werden können. Eine weitere Verstellmöglichkeit ergibt sich über die Erregerfrequenz für den Erreger 44.The plate 43 rests under pressure on the conveyor belt part 11, there being various possibilities for changing the position of the plate 43 and also the intensity of the vibration compressor 40. For example, slots 45 can be provided on the anchoring plate 41 so that the inclination of the plate 43, the distance to the conveyor belt part 11 and also the height, that is to say the distance to the washing trough 30, can be changed. A further adjustment possibility results from the excitation frequency for the exciter 44.

An Stelle der in der Zeichnung dargestellten Platte 43 kann auch eine Rolle eingesetzt werden, die ebenfalls über die gesamte Breite des Förderbandteiles 11 reicht, wobei der Einsatz. einer Platte 43 oder einer derartigen Rolle von dem zu bearbeitenden Material abhängt. In Abhängigkeit von dem Material und der Wasserhaltigkeit kann es notwendig sein, mehrere solche Vibrationsverdichter 40 vorzusehen.Instead of the plate 43 shown in the drawing, a roller can also be used, which also extends over the entire width of the conveyor belt part 11, the use. a plate 43 or such a roll depends on the material to be processed. Depending on the material and the water content, it may be necessary to provide several such vibration compressors 40.
