摘要： A cutting tool assembly (10) includes a support block (12), a replaceable spray nozzle housing, a liquid seal tight insert ring and first and second fluid passages. The first fluid and second fluid passage has an axis and extends between the concealable outer surface portion (22) and a first (20) surface portion of the support block. The first and second fluid passages are substantially straight between first and second outer surfaces so as to permit a drill to be inserted into first and second fluid passage for cleaning. The cutting tool assembly (10) also includes an exterior replaceable spray nozzle housing (14) on the support block having a cylindrical inlet portion (38) that extends into the first fluid passage such that the spray nozzle housing (14) is in fluid communication with the first fluid passage. A separate insert ring independent of a tool holding wear protective sleeve is press fit into the rear portion of the support block and forms an annular flow chamber section of the first fluid passage. The insert ring may be readily removed in the field to permit cleaning of the first fluid passage.

摘要： An assembly for mounting a cutter bit on a driven mechanism, the assembly comprising a bit having a bit tip, a bit sleeve including a holding portion adapted to receive the bit, a bore through the holding portion, and a bit holder. The assembly further includes a mounting base having a forward portion and a mounting base rear portion having an internal water passageway in communication with an upper opening for receiving an ignition control unit. The assembly further includes a rear surface having a spray nozzle cavity in the rear surface and open in a rearward direction. The spray nozzle cavity has an internal spray nozzle cavity water passageway-in communication with the mounting base rear portion internal water passageway. The assembly further includes a dust reduction unit including a spray nozzle comprising a base received in the spray nozzle cavity, the base having a spray nozzle base water passageway through the spray nozzle base and in communication with the spray nozzle receptacle water passageway. The dust reduction unit further includes a spray orifice in communication with the spray nozzle base water passageway, and a mechanism for connecting the spray nozzle to the mounting base rear portion.

摘要： A “wet” pick box 1 comprises a body member 2, adapted in use to be welded to a rotary cutting head, whilst an aperture 5 is provided in the body member. Bores 15, 16 in the body member define an internal water course 6 connectable, at an inlet end 7, to a source of pressurised water, an aperture 8 in the body member is adapted to house a water discharge nozzle and is connected to an outlet end 9 of the watercourse 6. A tapped hole 10 intersects the bores 15 and 16 and a member 11A or 11B is insertable into, and removable from, the hole 10. A rotary mineral cutting head can be provided to which a plurality of such pick boxes are welded.

摘要： A push-in, prise-out, clip (1) for releasably retaining a replaceable water spray nozzle (2) in a receiving bore (3), comprises a plate-like member of suitable resilient material, generally of “V” or “U”-shape having “C”-shaped recess (6) subtending an arc greater than 180° and adapted, in use, to engage a correspondingly arcuate waist portion (7) of the water spray nozzle (2). The recess (6) is defined in part by arcuate profiles (8) on mutually facing, inner surfaces (9) of each arm (10) of the “V” or “U”, which arms (10) are adapted to splay apart resiliently during the fitting and the removal of a clip on the water spray nozzle (2), whilst a portion of the clip (1) is provided with a clip retraction surface (12). The invention also includes a water spray nozzle (2), a pick box (4), and a rotary mineral cutting head (36).

摘要： A cutting tool assembly includes a support block having a concealable outer surface portion, first and second bores, and first and second fluid passages. The first fluid passage is in fluid communication with the first bore and the second fluid passage. The second fluid passage has an axis and extends between the concealable outer surface portion and the second bore. Furthermore, the second bore and the second fluid passage are configured such that the axis may be extended through the second bore and beyond the support block without intersecting the support block. The cutting tool assembly also includes a replaceable spray nozzle having a body that extends into the first bore such that the spray nozzle is in fluid communication with the first fluid passage.
