一种矿用截齿1、用于这种截齿的夹持器及其与夹持器2的组合。该截齿具有带有截割头5的头部3和容纳在夹持器2的柄插座6中的柄4。设置保持装置7以可释放地将截齿固定在夹持器中。穿过截齿延伸的是水通道11，其与截齿头部中的出水口12连通，以便水流以抑制灰尘并冷却尖端5。通道11与插座15连通，插座15与管状插口13配合，管状插口13是保持器2中流体供应通道2a的延伸部分。插口13由管状外壳19中的弹性套筒22安装，通过该弹性套筒将其可拆卸地保持在夹持器2中。套筒22允许插口13移动，以在其连接过程中适应插口与插座15之间的不对准。当杆插入其插座6时。插座6配备有塑料模制衬里23，该衬里在磨损时可更换以减轻对支架2的磨损。在一种改进方案中，管状插口由挑杆承载(并且可以与之一体)，用于与杆座6中的流体耦合插座配合。
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.
