摘要： The cutting head (1) has passages (14, 16; 22) extending through the cutting head in axial direction thereof and being connected with the axial water supply bore (8) by radial bores (9). Radial bores leading to the outlet nozzles open into the passages (14, 16; 22) extending through the cutting head in axial direction thereof. The passages (14, 16; 22) extending through the cutting head in axial direction thereof can be closed at at least one side by means of detachable closure members (15), so that these passages (14, 16; 22) extending through the cutting head in axial direction thereof can, after having removed the closure members, be cleaned by means of a cleaning-rod.

Radial passages (11) are provided which open into the distributing chamber and lead to the outlet openings at the periphery of the rotating cutting head. The distributing chamber is designed as a space coaxially surrounding the axial bore (3), being closed at its front side and having its mantle stationary arranged. At least two radial bores (9, 10) of opposite radial direction adjoin this annular space and are displaced in axial direction of the bore (3).

摘要： The device for intermittently subjecting axially shiftable bits of a cutting head to the action of pressurized fluids comprises bit holders in which the bits are supported for a limited movement in axial direction. The bits are subjected to the action of a percussion piston which is intermittently supplied with pressurized fluid. A distributor 6 is provided for intermittently supplying pressure and includes a bushing-shaped distributing slide valve 18. The distributing slide valve 18 is provided in its mantle surface with radial perforations 22 which can be brought in alignment with passages 7 of a cutting head 3. There is provided an interpositioned gearing comprising a sun wheel 13, intermediate gear wheels 11 bearingly supported on a carrier 10 fixed for not being rotatable and a hollow gear wheel 15 non-rotatably connected with the cutting head 3. The bushing-shaped distributing slide valve 18 is non-rotatably connected with the sun wheel 13 being rotated in this manner by the cutting head 3, noting that the distributing slide valve 18 is rotated in a sense opposite to the sense of rotation of the cutting head 3. Supply of water is effected via an intermediate piece 20 into an axial water supply bolt 9 from which the water is intermittently supplied to the percussion pistons within the bit holders via the perforations 22 of the distributing slide valve 18.

摘要： For reducing the risk of any overheating when cutting or crushing rock by means of a partial cut cutting machine and for facilitating crushing or, respectively, cutting of the material, a pressurized liquid, for example water, is intermittently sprayed within an area facing the area to be excavated. Said mentioned area facing the area to be excavated is realized in connection with a cutting head by providing within a range of center angle of the rotating movement of the cutting head a plurality of radial perforations (18) adjoining an axial bore (8) for the supply of pressurized fluid, noting that this range of central area corresponds to that area which faces the area to be excavated or, respectively, the mine face. Radial channels (22) of the cutting head coincide during rotation of the cutting head (1) with the radial perforations (18), said channels feeding the pressurized liquid to the exit openings provided on the periphery of the cutting head (1). The radial perforations (18) are arranged within a center angle of less than 180.degree., preferably 120.degree. to 150.degree., and with predetermined rotating speed of the cutting head (1) this provides the possibility to realize preferred ejection frequencies between 10 and 20 Hz.

摘要： For cutting rock by means of cutting head (1) having its bits (24) cooperating over a limited axial shifting stroke (a) with a cylinder-piston-aggregate, for example a valve (18), it is proposed to intermittently subject the cylinder-piston-aggregate to the action of pressurized fluid, thus exposing the bit (24) during its engaging the rock to percussion forces. During the phases lacking any action of pressurized fluid onto the cylinder-piston-aggregate, the bit (24) shall be pushed into its starting position. This embodiment can be realized with both hydraulic and pneumatic cylinder-piston-aggregates, noting that in case of an embodiment having a hydraulic cylinder-piston-aggregate it is preferred to design this cylinder-piston-aggregate as a valve (18) which simultaneously provides the possibility to expel pressurized liquid via a spraying nozzle (32) onto the mine face. (FIG. 2)

摘要： A bit holder equipped with a spraying device, comprising a receiving bore (2) in which the bit shaft (3) is supported, for limited axial shifting movement and optionally for being rotated, shifting movement of the bit shaft (3) in direction of the cutting pressure being limited by abutment (5) and the bit shaft being loaded by a return force in opposite direction to the cutting pressure and a valve (10, 11) for the supply of water to the bit or to the working or drift face during cutting operation being arranged within the bit holder (1) and being opened under the action of the cutting pressure by the axial shifting movement of the bit shaft (3). The valve housing (9) is inserted into the receiving bore (2). The rear end of the bit shaft (3) acts directly on the shaft (12) of the valve cone (10). Within the mantle of the receiving bore (2) and in front of the valve housing (9) there are provided passages (16) through which contaminations entering into the receiving bore (2) along the bit shaft (3) can be discharged in outward direction before they can arrive at the valve seat (11). The shaft (12) of the valve cone (10) is preferably guided within the valve housing (9), so that contaminations are rinsed in outward direction through the passages (16) by the leakage water flowing therethrough.
