    • A tool system for a mining machine. The tool comprises a tool holder (12) and a cutting tool pick (14) with a cutting tip (16). The mounting end of the tool comprises a tapered shank (18) in a corresponding tapered socket (20) of the tool holder (12). There may be a wear plate (24) situated between the tool holder (12) and the tool (14). There may be further removable wear plates (30) positioned between the tool holder and the tool in the shank region, these wear plates may have lateral projections (29) engaging corresponding recesses (32) in the shank region of the body (12). All these wear plates may be sacrificial and are able to be replaced upon wear, thus less damage will occur to the shank region of the tool or the holder body. The tool assembly may further include a pin (42) which can engage both the tool and holder by extending through aligned openings, opening (40) in the tool holder and opening (38) in the tool. The pin may be resiliently held in place. A spray unit (25) extends through the wear part (24) and has an outlet (25a) to direct fluid toward the cutting tip (16).
    • 采矿机械的工具系统。 该工具包括具有切割尖端(16)的刀架(12)和切削刀具拾取器(14)。 工具的安装端包括在工具架(12)的相应的锥形插座(20)中的锥形柄(18)。 可以存在位于工具保持器(12)和工具(14)之间的耐磨板(24)。 可以在刀柄区域中存在位于工具夹持器和工具之间的另外的可移除耐磨板(30),这些耐磨板可以具有与主体(12)的柄部区域中的相应凹部(32)接合的侧向突起(29)。 所有这些耐磨板可以是牺牲的,并且能够在磨损时更换,因此对刀具或保持器主体的柄部区域将产生较少的损伤。 工具组件还可以包括销(42),该销可以通过延伸穿过对准的开口,工具夹具中的开口(40)和工具中的开口(38)而接合工具和保持器。 销可以弹性地保持就位。 喷雾单元(25)延伸穿过磨损部分(24)并且具有出口(25a)以将流体引向切割尖端(16)。
