摘要： A replaceable tool support is disclosed. The tool support may be configured to be mounted to a base member of a cutting head, which may be mountable to a tool drum used in hard rock mining applications. The tool support may have an annular body having a first end face side. The tool support may also have a plurality of cutting bit carriers disposed spaced apart from each other on the first end face side. In addition, the tool support may have a plurality of cutting bits. Each of the plurality of cutting bits may be rotatably supported by one of the plurality of cutting bit carriers.

摘要： The present disclosure relates to a mobile mining machine which may comprise a movable machine base frame, a rotatable tool drum and including excavating tools. The mobile mining machine may further comprise a cantilever unit including a front support arm part and a base part, and a pivotal device to pivot the cantilever unit. The mobile mining machine may further comprise a tilt device to tilt the cantilever unit and a rotary mechanism to rotate the support arm part and the tool drum. Thus, a mobile mining machine with which tunnels, galleries or shafts may be continuously driven in even in hard rock with a high mining output and low tool wear may be provided.

摘要： A milling device is disclosed. The milling device may have a shaft. The shaft may have a shaft axis (A). The milling device may also have a spindle drum rotatably mounted relative to the shaft axis (A) and rotatable about a spindle drum axis (B) coaxial to the shaft axis (A). Further, the milling device may have a plurality of tool spindles rotatably mounted in the spindle drum and rotatable about tool spindle axes (D). Each tool spindle axis (D) may be parallely arranged and spaced apart from the shaft axis (A) and may have a same distance to the shaft axis (A). The milling machine may also have a plurality of machining tools carried by the tool spindles. At least two of the plurality of machining tools may be positioned displaced from one another in a direction of the shaft axis (A).

摘要： A cutting head for hard rock mining applications is disclosed. The cutting head may have a base member. The base member may have a rotational axis and may include a center bore extending along the rotational axis. The cutting head may also have a drive bushing disposed within the center bore. The drive bushing may be configured to transmit torque from a driving device to the base member. The cutting may further have a plurality of annular tool supports. Each of the plurality of annular tool supports may be concentrically disposed about the rotational axis in a releasable manner. In addition, the cutting head may have a plurality of cutting bit carriers attached to each of the plurality of annular tool supports. Each of the plurality of cutting bit carriers may be configured to rotatably support a cutting bit.

摘要： The present disclosure relates to a slat conveyor for transporting material in mining and extraction systems. The slat conveyor may comprise a plurality of channel elements arranged in a series, a material-transport strand and an oppositely-moving return strand. The slat conveyor may further comprise an endless conveyor including a conveyor chain and a plurality of transport plates with a plate section, which may be pivotable downward in a delivery area for the transported material. Thus, for example, a flat-constructed slat conveyor (apron conveyor) having a low loading height may be provided.

摘要： A rock feeder deflector device for a rock feeder used in underground mining applications. The rock feeder has a material transport portion for transporting rock material to a conveyor. The rock feeder deflector device comprises a mounting portion configured to be connected to the rock feeder; a guiding plate movably connected to the mounting portion; and a moving mechanism arranged between the mounting portion and the guiding plate. The moving mechanism is configured to move the guiding plate relative to the mounting portion between an operative position configured to guide rock material to the material transport portion and an inoperative position.

摘要： The present disclosure relates to a cutting bit carrier for hard rock mining applications. Usually, replacing worn cutting bits may take much effort and may be time consuming. The present cutting bit carrier may comprise a first carrier member including a first supporting portion configured to contact a cutting bit shank of a cutting bit for supporting the cutting bit, and a second carrier member including a second supporting portion configured to contact the cutting bit shank of the cutting bit for supporting the cutting bit. The second carrier member may be detachably mountable to the first carrier member.
