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： For sinking of shafts, a cutting machine (1) is provided having its cutting arm (3) pivotable around a vertical axis (4) and a horizontal axis (5). The cutting arm (3) carries cutting heads (14) which are rotatable around an axis (15) horizontally arranged and extending perpendicularly relative to the axis of the cutting arm. The shaft is now sunk around its circumference (9) in direction of its axis (10), for which purpose first the uppermost lead of a screw surface is prepared. On this uppermost lead of the screw surface the cutting machine is advanced until the cutting heads (14) contact the shaft wall (9). In the following, a floor cut (19) is made whereupon a further floor cut (20) is made at a lower level. Starting from a corresponding position of the cutting machine surfaces (23, 24) are cut free starting from the shaft wall (9). This manner of operation is continued thereby repeating the previous process steps until the whole screw surface is cut free, the cutting machine thereby being moved in backward direction. Any area (30) possibly remaining close to the axis of the shaft and being not within the operating range of the cutting arm can subsequently be broken away or be removed by cutting operating in another position of the cutting machine (FIG. 2).

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： A cutter machine has cutter heads or rollers rotatably mounted on a pivoting cutter arm. It also has a loading ramp and a conveyor running in a direction towards the work face of the cutter machine to take up and convey away cut material. The cutter arm is mounted on a sliding carriage which is displaceable along guides running in the longitudinal direction of the machine. The carriage is configured as a self-supporting box profile in a clear cross-section space of which a removal conveyor is mounted so that it may slide. For this reason, the cutter machine is particularly well-suited for use in small seam heights and for particularly low constructional design. It may nonetheless be used satisfactorily for operating reliably over a variable tunnel width.

摘要： A shearing machine with shearing heads or drums rotatably mounted on a luffable shearing arm and a loading ramp or a conveyor running in the direction of the heading face for receiving and conveying away the sheared material. The loading ramp or the conveyor is supported displaceably in the longitudinal direction of the shearing machine on the machine frame and the horizontal luffing axis of the shearing arm runs transversely to the longitudinal direction of the machine and is mounted adjustably relative to the machine frame in the longitudinal direction of the machine. The adjustment movement of the horizontal luffing axis of the shearing arm is coupled to the adjusting movement of the loading ramp or of the conveyor. The shearing arm is mounted on a bearing bracket which is connected to a carriage. The carriage is displaceable on guides running in the longitudinal direction of the machine and the bearing bracket is connected to a driver which is formed by a slot guide. After a predetermined displacement distance of the bearing bracket in the longitudinal direction of the machine, the bearing braket interacts with the conveyor.
