Description

Gegenstand der vorliegenden Erfindung ist eine Vorrichtung an Brechbacken für Steinbrecher u. dgl., bei welchen die eigentliche Arbeitsfläche mit aus hartem Stahl bestehenden Brechbacken versehen ist, während der übrige Teil der Backen aus weicherem Material, z. B. Gußeisen, besteht. Weil die Zähne der Arbeitsflächen nach verhältnismäßig kurzer Zeit wegen des starken Verschleißes gegen das zu brechende Material abgeschliffen werden, mußten die Brechbaeken früher häufig gegen neue vertauscht werden, was sehr kostspielig ist, besonders da die Backen ganz untauglich werden, sobald die Zähne abgeschliffen sind und diese nur einen geringen Teil der ganzen Backe bilden. Bei den Arbeitsflächen, bestehend aus losnehmbaren Stäben oder Vollplatten, war man bisher genötigt, diese Teile durch sogenannteThe present invention relates to a device on crushing jaws for stone crushers and the like, in which the actual work surface consists of hard steel Jaws are provided, while the rest of the jaws are made of softer material, z. B. cast iron. Because the teeth of the work surfaces after a relatively short time due to heavy wear be ground down against the material to be broken, the breaker jaws often had to be exchanged for new ones in the past, which is very expensive, especially since the jaws become completely disabled as soon as that Teeth are ground down and these form only a small part of the entire cheek. at The work surfaces, consisting of detachable rods or solid panels, have been used until now forced these parts by so-called

This fastening was sufficient for the large pressures and loads that occur did not meet the requirements of the practice and gave rise to constant disturbances. These

Übelstände werden durch die vorliegende Erfindung beseitigt, indem eine dauerhafte, allen Beanspruchungen gewachsene Befestigung der Arbeitsfläche mit ihrer Unterlage vorgesehen wird. Zwei Ausführungsformen sind in der Zeichnung veranschaulicht.Defects are eliminated by the present invention by a permanent, Fastening of the work surface with its base to withstand all stresses is provided. Two embodiments are illustrated in the drawing.

Fig. ι zeigt einen Schnitt durch einen Teil einer Brechbacke nach der Erfindung, undFig. Ι shows a section through part of a crushing jaw according to the invention, and

Fig. 2 ist ein ähnlicher Schnitt einer anderen Ausführungsform.Figure 2 is a similar section of another embodiment.

Nach Fig. 1 ist die auf bekannte Weise am Maschinengestell oder an dem beweglichen Arm der Maschine befestigte Brechbacke 1 auf ihrer der entgegengesetzten Backe zugekehrten Fläche mit schwalbenschwanzförmigen Spuren in einer Entfernung voneinander versehen, die der gewöhnlichen Entfernung zwischen den Zähnen der Backe entspricht. Diese Spuren umfassen in entsprechender Weise gestaltete Leisten 2 auf der Rückseite einer im Querschnitt zickzackförmigen, verhältnismäßig dünnen Platte 3, die aus hartem, widerstandskräftigem Material, z. B. Manganstahl, besteht. Die Platte bildet, auf an und für sich bekannte Weise die Arbeitsfläche der Backen. Zwischen den schwalbenschwanzförmigen Spuren der Backe sind. winkelförmige Erhöhungen oder Rücken 4 vorgesehen, die die Aussparungen der Platte 3 ausfüllen, wodurch teils eine Ersparnis an Material der Platte bewirkt wird, teils die Platte während der Arbeit in ihrem Platz sicherer gehalten wird. Die Platte 3 liegt nicht direkt gegen die Backe 1 an, sondern zwischen ihnen ist in bekannter Weise ein Zwischenraum vorgesehen, in welchem Zinn, Blei oder ein anderes wei-According to Fig. 1, in a known manner on the machine frame or on the movable Arm of the machine attached breaking jaw 1 on its opposite jaw facing surface with dovetail-shaped Traces are provided at a distance from each other that is the usual distance between corresponds to the teeth of the cheek. These tracks comprise strips 2 designed in a corresponding manner on the rear side of a in cross-section zigzag-shaped, relatively thin plate 3, which is made of hard, resistant Material, e.g. B. manganese steel exists. The plate forms, in and of itself known way the working surface of the jaws. Between the dovetail-shaped Traces of the cheek are. angular elevations or back 4 is provided, which fill the recesses of the plate 3, whereby partly a saving of material of the plate is effected, partly the plate during the Work is held more securely in its place. The plate 3 is not directly against the Jaw 1, but between them a space is provided in a known manner, in which tin, lead or some other white
