Description

Die Erfindung betrifft einen Vibrationsbackenbrecher, be­stehend aus einem Gehäuse, in dem zwei Backen angeordnet sind, deren Arbeitsoberflächen in Form einer konvexen und konkaven gebrochenen Linie ausgebildet sind und von denen wenigstens einer beweglich und mit einem Vibrator versehen ist.The invention relates to a vibratory jaw crusher, consisting of a housing in which two jaws are arranged, the working surfaces of which are designed in the form of a convex and concave broken line and at least one of which is movable and provided with a vibrator.

Ein solcher, aus der SU-A-1 005 892 bekannter Vibrations­backenbrecher hat ein Gehäuse, in dem ein unbeweglicher Backen und ein beweglicher Backen angeordnet sind, von denen der letztere an seinem oberen Ende mittels einer Achse gelenkig befestigt ist. Die Arbeitsoberflächen beider Backen sind in Form einer kovexen bzw. konkaven gebrochenen Linie ausgebildet, wobei die Arbeitskammer, d.h. der Raum zwischen den beiden Backen, die Form eines unsymmetrischen Keils aufweist. Der bewegliche Backen wird von einem Schwingantrieb vibrieren gelassen.Such a vibratory jaw crusher known from SU-A-1 005 892 has a housing in which an immovable jaw and a movable jaw are arranged, the latter of which is articulated at its upper end by means of an axis. The working surfaces of both jaws are designed in the form of a covex or concave broken line, the working chamber, i.e. the space between the two jaws has the shape of an asymmetrical wedge. The movable jaw is vibrated by an oscillating drive.

Bei dem bekannten Vibrationsbackenbrecher werden die Brech­platten bei der Zerkleinerung von Betonblöcken, Plattenbau­elementen oder anderen Werkstoffen mit flacher Form, die eine große Masse aufweisen ungleichmäßig belastet. Dies beeinträchtigt die Verschleißbeständigkeit der Arbeitsober­flächen und erhöht den Energieaufwand pro Masseneinheit bei der Zerkleinerung.In the known vibratory jaw crusher, the crushing plates are unevenly loaded when crushing concrete blocks, plate components or other flat-shaped materials that have a large mass. This affects the wear resistance of the work surfaces and increases the energy expenditure per unit of mass during shredding.

Der Erfindung liegt deshalb die Aufgabe zugrunde, den Vibrationsbackenbrecher der gattungsgemäßen Art so auszu­bilden, daß bei einfachem Aufbau eine gleichmäßige Belastung der Arbeitsoberflächen der Backen gewährleistet ist.The invention is therefore based on the object of designing the vibratory jaw crusher of the generic type in such a way that, with a simple structure, uniform loading of the working surfaces of the jaws is ensured.

Diese Aufgabe wird ausgehend von dem Vibrationsbacken­brecher der eingangs genannten Art dadurch gelöst, daß der bewegliche Backen an seinem oberen und unteren Teil durch elastische Elemente an dem Gehäuse befestigt ist.This object is achieved on the basis of the vibratory jaw crusher of the type mentioned at the outset in that the movable jaw is fastened to the housing by elastic elements on its upper and lower part.

Gelöst wird diese Aufgabe auch dadurch, daß beide Backen an ihrem oberen Ende jeweils über eine Schwenkachse und an ihrem unteren Ende jeweils über ein elastisches Element gehalten und mit einem Vibrator verbunden sind.This object is also achieved in that both jaws are each held at their upper end via a pivot axis and at their lower end via an elastic element and are connected to a vibrator.

Zweckmäßigerweise ist jedes der elastischen Elemente ein Gummipolster.Each of the elastic elements is expediently a rubber cushion.

Der Vorteil des erfindungsgemäßen Vibrationsbackenbrechers liegt in seiner einfachen Konstruktion, bei der das Auf­hängen des beweglichen Backens mittels elastischer Elemente, z.B. Gummipolster, eine gleichmäßige Belastung der Arbeits­oberflächen und somit der Backen bei der Zerkleinerung von Baustoffen in Form von Blöcken oder Platten ermöglicht.The advantage of the vibratory jaw crusher according to the invention lies in its simple construction, in which the movable jaw is suspended by means of elastic elements, e.g. Rubber padding, an even load on the work surfaces and thus the jaws when crushing building materials in the form of blocks or plates.

Anhand von Zeichnungen werden Ausführungsbeispiele der Erfindung näher erläutert. Es zeigt:

  • Fig. 1 schematisch in einer Seitenansicht eine erste Aus­führungsform eines Vibrationsbackenbrechers und
  • Fig. 2 in einer Ansicht wie Fig. 1 eine zweite Aus­führungsform.
Exemplary embodiments of the invention are explained in more detail with reference to drawings. It shows:
  • Fig. 1 shows schematically in a side view a first embodiment of a vibratory jaw crusher and
  • Fig. 2 in a view like Fig. 1 shows a second embodiment.

Der in Fig. 1 gezeigte Vibrationbackenbrecher besteht aus einem Gehäuse 1, in dem ein unbeweglicher Backen 2 und ein beweglicher Backen 3 angeordnet sind, wobei der be­wegliche Backen 3 mittels elastischer Elemente 4 und 5 an seinem oberen und unteren Ende aufgehängt ist. An dem elastischen Element 5, das am unteren Ende des beweglichen Backens 3 angebracht ist, ist eine Einrichtung 6 zur Regulierung der Auslaßöffnung 7 des Vibrationsbacken­brechers vorgesehen. Der bewegliche Backen 3 ist mit einem Vibrator 8 ausgerüstet, der zwischen den beiden abstützenden elastischen Elementen 4 und 5 angeordnet ist. Die von den Arbeitsoberflächen der Backen 2 und 3 gebildete Zerkleinerungszone bildet einen krummlinigen asymmetrischen Keil, der zu der horizontalen Ebene geneigt ist.The vibration jaw crusher shown in Fig. 1 consists of a housing 1, in which an immovable jaw 2 and a movable jaw 3 are arranged, the movable jaw 3 being suspended by elastic elements 4 and 5 at its upper and lower ends. On the elastic element 5, which is attached to the lower end of the movable jaw 3, a device 6 is provided for regulating the outlet opening 7 of the vibrating jaw crusher. The movable jaw 3 is equipped with a vibrator 8, which is arranged between the two supporting elastic elements 4 and 5. The crushing zone formed by the working surfaces of the jaws 2 and 3 forms a curvilinear asymmetrical wedge which is inclined to the horizontal plane.

Bei der in Fig. 2 dargestellten Ausführungsvariante des Vibrationsbackenbrechers sind beide Backen 2 und 3 über Schwenkachsen an ihrem oberen Teil gelenkig aufgehängt, während das untere Ende der Backen 2 und 3 jeweils auf einem elastischen Element 5 in Form eines Gummipolsters aufliegt. An dem abstützenden elastischen Element 5 des Backens 3 ist eine Einrichtung zum Regulieren der Aus­laßöffnung 7 vorgesehen. Bei dieser Ausführungsform ist an jedem der beiden Backen 2 und 3 ein Vibrator 8 vor­gesehen.In the variant of the vibratory jaw crusher shown in FIG. 2, both jaws 2 and 3 are hinged on their upper part via pivot axes, while the lower end of the jaws 2 and 3 each rests on an elastic element 5 in the form of a rubber cushion. A device for regulating the outlet opening 7 is provided on the supporting elastic element 5 of the jaw 3. In this embodiment, a vibrator 8 is provided on each of the two jaws 2 and 3.

Auf einem durch die Einlaßöffnung 9 eingebrachten Beton­block werden auf seinem Weg zu dem enger werdenden Bereich der Arbeitskammer Hochfrequenzschläge von wenigstens dem beweglichen Backen 3 bzw. 2 und 3 erteilt, die durch den Vibrator 8 erzeugt werden, beispielsweise mit einer Frequenz von 50 Hz und einer Amplitude bis 3 mm. Aufgrund der dadurch bedingten konstanten Biegespannungen im zu zerkleinernden Betonblock bilden sich Trümmer und schließ­lich Stücke, die den Vibrationsbackenbrecher durch die Auslaßöffnung 7 verlassen können. Dabei findet eine Überlastung der Arbeits- und Antriebselemente des Vibrationsbackenbrechers nicht statt.On a concrete block introduced through the inlet opening 9, on its way to the narrowing area of the working chamber, high-frequency impacts from at least the movable jaws 3 or 2 and 3 are given, which are generated by the vibrator 8, for example with a frequency of 50 Hz and a Amplitude up to 3 mm. Due to the resulting constant bending stresses in the concrete block to be crushed, debris and finally pieces are formed which can leave the vibratory jaw crusher through the outlet opening 7. One finds Do not overload the work and drive elements of the vibratory jaw crusher.
