摘要： A cutting assembly for a mining machine includes a mount configured to move about a first axis relative to a chassis of the mining machine and a ranging arm coupled to the mount. The ranging arm is moveable relative to the mount. The cutting assembly includes a cutting head having a housing coupled to the ranging arm. The housing is moveable relative to the ranging arm. The cutting head includes a drum supported for rotation relative to the housing about a rotational axis, a plurality of cutting bits coupled to the drum, and at least one motor supported by the housing to drive the drum about the rotational axis.

摘要： The invention relates to a milling machine having a replaceable milling drum, different types of milling drums being capable of being associated with the milling machine; and having a control unit for controlling the milling machine, machine parameters of the milling machine being settable by way of the control unit. Provision is made that the milling machine has associated with it at least one means that is designed to detect at least one characteristic feature of the milling drum; that the at least one means is connected to the control unit; and that the control unit is designed to specify for at least one machine parameter, indirectly or directly from the characteristic feature, a value to be set, and/or a setting range. The invention further relates to a corresponding milling drum and to a corresponding method. The milling machine, milling drum, and method allow the selection of machine parameters for operation of the milling machine to be simplified.

摘要： The invention relates to a milling machine, in particular a road milling machine, a stabiliser, a recycler or a surface miner, comprising a drive means which is configured such that the milling machine performs translatory and/or rotatory movements on the ground, and a working means which is configured such that the ground is machined. The invention also relates to a method for operating a milling machine of this type. The milling machine according to the invention has a control unit 15 to input drive parameters and work parameters. The control unit 15 is distinguished by a selection unit 15C to select an operating mode from a plurality of operating modes. The control and processing unit 20 has a memory 20A which stores at least one predetermined drive parameter which is assigned to the operating mode, and/or at least one predetermined work parameter which is assigned to the operating mode, for each operating mode of the plurality of operating modes. The control and processing unit 20 is configured such that at least one assembly 4, 5; 8, 10, 11, 12, 13, 17, 18, 19 of the drive means and working means is controlled subject to the at least one drive parameter or work parameter which is stored in the memory 20A for the operating mode selected using the selection unit 15C, such that the particular machine function is carried out. The milling machine further provides that at least one function which describes the dependence of a work parameter of one assembly on a drive parameter of another assembly is stored for each operating mode, the control and processing unit 20 being configured such that, based on this function, at least one assembly of the working means or drive means is controlled such that the particular machine function is carried out.

摘要： A shearer cutting unit with double-speed rollers includes a motor driving unit, a motor driving unit, a gear transmission unit and a roller output unit. The motor driving unit includes a left cutting motor and a right cutting motor which are both arranged in a cutting unit case and connected with the roller output unit in a transmission way through the gear transmission unit. The roller output unit comprises a middle output shaft (3-1), a far-end output shaft, a middle support frame, a middle roller, a far-end support frame and a far-end roller. A cutting roller is separated into two coaxially-rotating parts, and the two rollers can rotate in different speeds.

摘要： A combination bit and bit holder assembly includes a bit holder having a forward body portion and a shank. The forward body portion includes an upper end and a lower end. An insert is mounted in the bore of the upper end of the body portion. The insert also includes a central bore that receivingly retains a receiving cup. The receiving cup includes a bottom portion and an annular flange that extends from the bottom portion and defines a hollow forward portion. A bit is mounted in the hollow forward portion of the receiving cup which is configured to have a ductility that provides impact absorption to the bit.

摘要： A tool holder is disclosed for use with a milling drum. The tool holder may have a cylindrical body defining a first end and a second end, the first end configured to be received within a tool mounting block of the milling drum, the second end configured to receive a cutting bit. A flange may be located between the first and second end with respect to an axial direction, and a first bore, with a first opening defined by the second end and extending towards the first end. A frustoconical portion may be located between the flange and the first end with respect to the axial direction and a cylindrical portion located between the flange and the first end. At least one radial opening may pass through at least the wall of the cylindrical portion to intersect or be open to the first bore.

摘要： An implement system for a machine includes a boom housing a drive mechanism for a cutting implement, and having a plurality of oil outlet ports formed therein. A control mechanism is configured to receive data indicative of an expected change in location of the outlet ports relative to an oil fill line within the boom, and vary a pattern of incoming oil flow to limit entrainment of air in the oil.
