Description

  

  Verfahren zum Abbau im Sandsteinbruch und Werkzeug zur Durchführung desselben    Das     Verfahren    zum Abbau im     Sandstein-          brucli    nach vorliegender Erfindung hat den  Zweck, das     Handschroten    und auch die Stein  gewinnung durch Bohren zu ersetzen und  kennzeichnet sich dadurch, dass die Schlitze  (oder Sehröte) durch ein kraftangetriebenes       Schroteisen    bewerkstelligt werden. Zur Durch  führung des erfindungsgemässen Verfahrens  bedient man sich eines     Werkzeuges    in Form  eines kraftangetriebenen Schroteisens mit  mehreren     Schneiden,    von denen mindestens       eine    andern in Schlagrichtung vorsteht.  



  Wenn das     hiefür    verwendete Schroteisen  die gewünschte Breite des Schlitzes aufweist,  so ist die Herstellung des Schrotes in einem  einzigen Arbeitsgang möglich. Das Ausschla  gen der beim Bohren entstehenden Steinrippe  fällt weg. Es lässt sieh somit eine beträchtliche       Leistungssteigerung    erzielen. Der Verschleiss  an Schroteisen kann bedeutend geringer sein,       cla    dieses Instrument den Stein ausbricht. und  somit nicht der Schleifwirkung im Bohrloch  ausgesetzt ist.  



  Ein Ausführungsbeispiel des erfindungs  gemässen     Werkzeuges    ist auf beiliegender       Zeichnung    dargestellt, in welcher         Fig.    1 das Schroteisen in der Draufsicht  und       Fig.    2 in der Seitenansicht darstellt.  



  Das     Sehroteisen    1 wurde in die erforder  liche Breite geschmiedet, aufgespalten und       hernaeh    wurden die Schneiden '2 und 3 her  ausgearbeitet. Die Schneiden können aus dem  gleichen Material sein wie der Körper des  Schroteisens 1, sie können aber auch als  Einsatz hergestellt und aufgesetzt werden.  Wenigstens eine der Schneiden, hier die mitt  lere, 3, steht den andern beiden 2 in Schlag  richtung vor. Es können auch mehr als drei  Schneiden vorgesehen sein, die in Schlagrich  tung abgestuft angeordnet sind.



  Method for mining in the sandstone quarry and tools for carrying out the same The method for mining in the sandstone quarry according to the present invention has the purpose of replacing the hand-grinding and stone extraction by drilling and is characterized by the fact that the slots (or very holes) have a powered shot iron can be accomplished. To carry out the method according to the invention, a tool is used in the form of a power-driven shot iron with several cutting edges, of which at least one other protrudes in the direction of impact.



  If the shot iron used for this has the desired width of the slot, the shot can be produced in a single operation. There is no need to knock out the stone rib that occurs during drilling. It can thus achieve a considerable increase in performance. The wear and tear on the shot iron can be significantly less because this instrument breaks the stone. and is therefore not exposed to the grinding action in the borehole.



  An embodiment of the tool according to the Invention is shown in the accompanying drawing, in which Fig. 1 shows the shot iron in plan view and Fig. 2 in side view.



  The sighting iron 1 was forged into the required width, split and the cutting edges 2 and 3 were worked out. The cutting edges can be made of the same material as the body of the shot iron 1, but they can also be manufactured and placed as an insert. At least one of the cutting edges, here the middle one, 3, protrudes from the other two 2 in the direction of impact. More than three cutting edges can also be provided, which are arranged stepped in the direction of impact.
