摘要： The loading ramp (1) of a heading machine or longwall shearing machine has swivelable loading arms by means of which the cut material is removed onto a conveying means. The surface of the loading ramp (1) can be increased by outwardly swivelling of parts (2). The loading arms (5) are driven by using a pivotal point (6) on a rotary disc (7), noting that a further swivel point (12) is provided outwardly of the circle described by a rotary pivotal point (6) on the rotary disc. The loading arm (5) is guided in a shiftable manner at the swivel point (12) and sweeps when driving the rotary disc (7) over a removal area (15, 18) defined by the relative position of the pivotal point (6) and the swivel point (12). The swivel point (12) is connected with the laterally extendable part (2) and is displaced together with the laterally extendable part (2) thus varying the removal area (15, 18).

摘要： A device for feeding cooling fluid into the inside of a shearing drum. The rotary drive of the shearing drum has at least one gear reduction mechanism contained within the hollow shearing drum. Fluid lines are led into the axial region of the shearing drum via a component which is stationary and rigidly connected to the carrier of the shearing drum. The gear reduction mechanism is arranged concentric with the axis and at least one of the fluid lines is led to at least one lateral end face where the fluid line supplies a fluid distributor which in turn distributes the fluid to various jets and fluid lines.

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 supplying a pressurized cooling liquid to the outlet openings in a cutting head, there is provided an axial supply bore (3) opening into a distributing chamber. 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). The cutting head is sealingly guided on the non-rotating mantle of the annular space.

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.
