The invention concerns a cutter pick mounting apparatus which is used to mount a cutter pick (10) to a pick box (12) which is secured to the drum of a mining machine. The cutter pick has a pick body (14) having a base (25) of circular cross-section and a shank (26) of smaller circular cross-section extending from the base. The shank is eccentric with respect to the base. The pick box is formed with a countersunk socket (30) that has a base-receiving recess (32) and a shank-receiving bore (34) which extends from the base of the recess. The bore is eccentric with respect to the recess, the eccentricity (38) corresponding to the eccentricity (28) of the shank of the pick body with respect to the base of the pick body. With this configuration the pick body (14) can be held non-rotatably in the socket (30) with the base locating complementally in the recess and the shank locating complementally in the bore. |
