The present invention relates to an improved ripper boot and, in particular, to a ripper boot for use in a range of applications involving the ripping or cleaving of hard material such as that encountered in opal mining. Problems have been encountered with particles becoming clogged in the space between the tooth shank and the carrier cavity, this being a result of the forwardly disposed gap between the tooth head portion and the carrier section, and the configuration of mating walls. The result is that the tooth can become caked inside the socket to an extent where it can no longer be removed. In order to alleviate this problem there is proposed a ripper boot characterised by a carrier adapted to be fixedly connected to a shank of a vehicle the carrier including an inwardly tapered male projection, a tooth including a hollow body and a head, the hollow body defining a female socket being correspondingly shaped with said male projection for engagement therewith. Typically the engagement is achieved by an interference fit. 10a 1Oa 14 06 20 36 Fig. 1 Fig. 2 16 10a 14 Fig 3 10a 14 Fig. 4 |
