Abstract

Rock drill bit with hard metla tip in which the bit with tip and guide ring can be exchanged, as also the transport spirals (lands) for the drillings which can similarly be plugged into position as and when required. This makes for a versatile drill unit, with hard wearing properties to suit the abrasive materials being driven out from the hole base. The drill tip may be a hard metal, of the tungsten carbide type, or of diamond. The drill has pref. a two or three start spiral, and this is plugged directly onto the central borer shaft.

Wachmannstrasse 22nd PATENTBESCHREIBUNGPATENT DESCRIPTION Betr.: Gesteinsbohrer mit Hartmetallbestückung und auswechselbarem Bohrkopf, sowie auswechselbarer SpiraleRe: rock drill with carbide tipping and exchangeable drill head, as well as exchangeable spiral Bekannt sind Gesteinsbohrer mit einer 2-seitig schneidenden Hartmetallbestückung, wobei das Hartmetall an dem Bohrschaft direkt festgelötet ist. Bekannt sind weiter Gesteinsbohrer mit auswechselbaren Bohrkronen, die mit mehreren Hartmetallschneiden versehen sind. Diese Gesteinsbohrer werden bei besonders großen Bohrungen eingesetzt.Rock drills with a two-sided cutting hard metal fitting are known, the hard metal on the drill shank is directly soldered. Rock drills with interchangeable drill bits with several hard metal cutting edges are also known are provided. These rock drills are used for particularly large bores. Bei vorliegender Patentanmeldung handelt es sich um einen Gesteinsbohrer, der aus mehreren auswechselbaren Bestandteilen besteht und zwar sind die Teile auswechselbar, die einem besonders großen Verschleiß unterliegen. Diese auswechselbaren Teile werden aus besonders hochwertigem und verschleißfestem Material hergestellt.The present patent application is a Rock drill, which consists of several interchangeable components and that the parts are interchangeable, which one are subject to particularly great wear. These interchangeable parts are made of particularly high quality and wear-resistant Material made. Figur I zeigt einen Gesteinsbohrer mit 3 Schneiden in auswechselbarer Bohrkrone (1), bestückt mit Hartmetall oder Dia» mant (2). Die Transportspirale (3)» die das Bohrmehl aus dem Bohrloch führt, ist ebenfalls auswechselbar und besteht aus hochfestem Material. FIG. I shows a rock drill with 3 cutting edges in an exchangeable drill bit (1), equipped with hard metal or diamond (2). The spiral transport (3) »that guides the drill dust out of the borehole is also replaceable and is made of high-strength material. Weiter erhält der Gesteinsbohrer einen über die Bohrkrone angebrachten Führungsring, der ebenfalls auswechselbar ist.The rock drill also receives one attached over the drill bit Guide ring, which is also exchangeable. PATENTANSPRÜCHEPATENT CLAIMS Gesteinsbohrer, dadurch gekennzeichnet, daß die Bohrmehl-Transportspirale (3) und der Bohrkopf (1)» bestückt mit Hartmetall oder Diamant (2) und dem Führungsring (4) so ausgebildet ist, daß diese ausgewechselt werden können.Rock drill, characterized in that the drill dust transport spiral (3) and the drill head (1) »fitted with hard metal or diamond (2) and the guide ring (4) is designed in such a way that that these can be exchanged. 509815/0155 .509815/0155.
