IMPROVEMENTS IN COAL AND ROCK PICKS

摘要

The invention relates to a coal or rock pick which consists of a pick body with a cone shaped head (8) having a shank (9) extending therefrom and a securing clip (18) housed in a circumferential groove (11) adjacent the end of the shank remote from the head (8). An open ended longitudinal axial bore (12) extends into the pick body from the head (8) which constitutes a magazine for an array of pick points (13, 14) or an elongated pick point housed therein. Preferably the securing clip (18) comprises a sleeve formed of plastic elastomeric material having a smooth internal bore (19) and an external circumferential flange (20) intermediate its ends. The inner diameter and length of the sleeve being such that it can be force fitted over the shank and accommodated in the circumferential groove (11).
