Description

Rohstoffknappheit, wachsende Müllberge und steigende Deponiekosten zwingen die Bauindustrie immer mehr dazu, Natursteine und Altstoffe wieder zu verwenden. Dazu setzt sie zum Teil mobile Brech- und Recycling-Anlagen ein. Bekannte mobile Brechanlagen werden mit einem LKW oder Spezialtieflader zum Recycling-Platz transportiert. Die mobilen Brechanlagen sind dabei mit einem Aufnahmetrichter, einer Zerkleinerungsvorrichtung und einer Förderanlage ausgestattet. Ein Dieselmotor treibt die Brechanlage an. Für das Zerkleinern werden Backenbrecher und Prallbrecher eingesetzt. Beim Backenbrecher erfolgt die Zerkleinerung durch Druck- und Scherkräfte zwischen einer festen und einer beweglichen Brechbacke. Beim Prallbrecher hingegen arbeitet man mit Schlagleisten, die beim Brechvorgang gegen das Material prallen, wodurch es zerkleinert wird. Backen- und Prallbrecher haben jedoch den Nachteil, dass sie hohe Investitionen erfordern. Außerdem weisen beide Anlagen einen hohen Rüst- und Wartungsaufwand auf, wodurch sie besonders bei kleinen Mengen und räumlich beengten Baustellen unwirtschaftlich sind.Shortage of raw materials, growing mountains of refuse and rising landfill costs are forcing the construction industry to reuse natural stones and existing materials. For this purpose, it uses partly mobile crushing and recycling plants. Known mobile crushing plants are transported to the recycling site by truck or special low-loader. The mobile crushers are equipped with a receiving hopper, a crushing device and a conveyor system. A diesel engine drives the crushing plant. For crushing jaw crushers and impact crushers are used. The jaw crusher is crushed by pressure and shear forces between a fixed and a movable crushing jaw. In the case of the impact crusher, on the other hand, one works with blow bars which collide against the material during the crushing process, whereby it is crushed. However, jaw and impact crushers have the disadvantage that they require high investment. In addition, both systems have a high set-up and maintenance, making them uneconomical especially for small quantities and cramped construction sites.

Aus der WO 95/27111 ist ein Pulverisierer für den Abbruch von Gebäuden bekannt, der das zu zerkleinernde Material zwischen zwei gegeneinander beweglichen Backen zerkleinert. Zwischen den Backen kann jedoch kein zu zerkleinerndes Material gespeichert werden.From WO 95/27111 a pulverizer for the demolition of buildings is known, which comminutes the material to be crushed between two mutually movable jaws. However, no material to be shredded can be stored between the jaws.

Die US 5,619,811 beschreibt eine Vorrichtung zur Zerkleinerung von Bodenmaterial mit einer Schaufel, die mit zwei Reihen von Wellen versehen ist. Die erste Reihe weist vier gleichsinnig rotierende Wellen auf, die mit gegenseitig kämmenden Scheiben versehen sind. Die kämmenden Scheiben sind nicht in der Lage, grobes und hartes Material wie Steine zu zerkleinern. Sie lassen nur bereits relativ feines und weiches Material zur zweiten Reihe von Wellen durch, die mit propellerartigen Belüftungsschaufeln versehen sind, die das Material lockern.US 5,619,811 describes a device for crushing soil material with a blade provided with two rows of shafts. The first row has four corotating shafts, which are provided with mutually intermeshing discs. The meshing discs are unable to crush coarse and hard material such as stones. They pass only relatively fine and soft material to the second series of waves, which are provided with propeller-like ventilation blades, which loosen the material.

Auch aus der US 5,485,689 ist eine Brechvorrichtung mit einer Schaufel bekannt, in der mehrere, gleichsinnig rotierende Wellen angeordnet sind, die nur im Zusammenwirken mit einer schwenkbaren Anpressplatte ein ausreichendes Zerkleinerungsergebnis erzielen.A breaking device with a blade is also known from US Pat. No. 5,485,689, in which several shafts rotating in the same direction are arranged, which only achieve a sufficient crushing result in cooperation with a pivotable pressure plate.

Die vorliegende Erfindung hat die Aufgabe, eine Zerkleinerungsvorrichtung von Steinen oder dergleichen dahingehend zu verbessern, dass der technische Aufwand für die Vorrichtung bei dennoch effektiver und qualitativ guter Arbeitsweise erheblich reduziert wird.The present invention has the object to improve a crushing device of stones or the like to the effect that the technical complexity of the device is significantly reduced while still effective and good quality operation.

Die Erfindung löst die gestellte Aufgabe durch eine mobile Vorrichtung zum Zerkleinern von Steinen oder dergleichen mit den Merkmalen des Anspruchs 1. Diese mobile Zerkleinerungsvorrichtung ist wesentlich preiswerter und auch leichter handhabbar als bisher bekannte Vorrichtungen.The invention solves the problem by a mobile device for crushing stones or the like with the features of claim 1. This mobile crushing device is much cheaper and easier to handle than previously known devices.

Die mobile Zerkleinerungsvorrichtung kann mittels einer Schnellwechseleinrichtung montiert und demontiert werden. Somit erfolgt der Wechsel der Zerkleinerungsvorrichtung in kurzer Zeit mit wenigen Handgriffen.The mobile crushing device can be assembled and disassembled by means of a quick-change device. Thus, the change of the crushing device takes place in a short time with a few simple steps.

Um das ohnehin schon am Bagger oder Lader vorhandene Hydrauliksystem optimal zu nutzen, kann die mobile Zerkleinerungsvorrichtung mittels der Hydraulik des Baggers oder Laders angetrieben werden.In order to optimally use the already existing on the excavator or loader hydraulic system, the mobile crushing device can be powered by the hydraulic system of the excavator or loader.

Sollte am Bagger oder Lader keine Anschlussvorrichtung an das Hydrauliksystem vorhanden sein, so kann eine separate Antriebsvorrichtung die Zerkleinerungsvorrichtung antreiben, die vom Bagger oder Lader angesteuert werden kann.Should there be no connection device to the hydraulic system on the excavator or loader, then a separate drive device can drive the comminution device, which can be controlled by the excavator or loader.

Damit das Zerkleinerungsgut optimal zerkleinert werden kann, weist die Zerkleinerungsvorrichtung mindestens zwei sich gegeneinander drehende Rotationswellen auf, wobei die mindestens zwei sich gegeneinander drehenden Rotationswellen mit Brechschlegeln ausgerüstet sind. Diese Art der Zerkleinerung erfordert weniger Investitionsaufwand als Backenbrecher oder Prallbrecher.Thus, the crushed material can be optimally crushed, the crushing device has at least two mutually rotating rotational shafts, wherein the at least two mutually rotating rotating shafts are equipped with crushing nuggets. This type of shredding requires less investment than jaw crushers or impact crushers.

Je nach Größe der zu zerkleinernden Steine kann der gegenseitige Abstand der mindestens zwei Rotationswellen vorzugsweise entsprechend einstellbar sein.Depending on the size of the stones to be crushed, the mutual distance of the at least two rotation shafts may preferably be correspondingly adjustable.

Zur besseren Aufnahme des zu zerkleinernden Materials kann die mobile Zerkleinerungsvorrichtung in ihrem vorderen Bereich ein Aufnahmemesser aufweisen.For better absorption of the material to be shredded, the mobile shredding device can have a receiving blade in its front region.

Damit zur Zerkleinerung genügend Material angesammelt werden kann, weist die Zerkleinerungsvorrichtung eine Füllkammer auf, in deren unterem Bereich die Rotationswellen angeordnet sind.So that sufficient material can be accumulated for comminution, the comminution device has a filling chamber, in the lower region of which the rotation shafts are arranged.

Nachfolgend wird ein Ausführungsbeispiel einer erfindungsgemäßen mobilen Zerkleinerungsvorrichtung anhand der beiliegenden Zeichnung näher erläutert.Hereinafter, an embodiment of a mobile crushing device according to the invention will be explained in more detail with reference to the accompanying drawings.
