ABSTRACT:
A mineral mining pick 1, a holder for such a pick, and the combination of such a pick with a holder 2. The pick has a head 3 with a cutting tip 5 and a shank 4 which is received in a shank socket 6 of the holder 2. Retaining means 7 is provided to releasably secure the pick in the holder. Extending through the pick is a water passage 11 which communicates with outlet ports 12 in the pick head for water flow to suppress dust and cool the tip 5. The passage 11 communicates with a socket 15 which mates with a tubular spigot 13 which is an extension to a fluid supply passage 2a in the holder 2. The spigot 13 is mounted by a resilient sleeve 22 in a tubular housing 19 by which it is removably retained in the holder 2. The sleeve 22 permits displacement of the spigot 13 to accommodate misalignment between the spigot and the socket 15 during coupling thereof as the shank is inserted into its socket 6.
The socket 6 is provided with a plastics moulded lining 23 which is replaceable when worn to alleviate wear on the holder 2.
In a modification the tubular spigot is carried by (and may be integral with) the pick shank for mating with a fluid coupling socket in the shank socket 6.
