摘要： A self-propelled construction machine for milling a ground surface is provided with a machine frame, a working drum, and a transport conveyor with a discharge end from which worked-off milling material is dischargeable onto a point of impingement on a loading surface of a transport vehicle, wherein the transport conveyor is laterally slewable to a slewing angle about at least a first slewing axis. A controller is configured, during an initialization process, to specify a command variable within a coordinate system, the coordinate system being stored during the initialization process with its origin at a starting point associated with the machine. The controller is further configured during a working process, wherein the coordinate system is stationary, to automatically control the slewing angle corresponding to detected changes in position and/or orientation of the machine and relative to the command variable.

摘要： A method for controlling the supply of fluid to a combine, wherein fluid is fed for actuating hydraulic cylinders 14, 15 of the drive for moving the combine and to a dust suppression hydraulic system 1. The same fluid, which is discharged from the hydraulic cylinders 14, 15, is used for feeding it at a pre-set pressure to the hydraulic system 1 for emergence under the flowthrough conditions. For that purpose, the dust suppression hydraulic system 1 communicates, via a fluid distributor 13, with the hydraulic cylinders 14, 15 to define an open-circuit hydraulic system.

摘要： A thrust device for a coal cutter running on a sectional string of trunking of a chain conveyor comprises a pinion on the coal cutter cooperating with a rack located on the conveyor. The rack is formed of a plurality of linked sections only one of which is firmly attached to the conveyor, the other sections being guided for longitudinal movement relative to the conveyor. The purpose of this arrangement is to avoid straining the rack or producing tooth pitch variations at the junctions of adjacent rack sections when the trunking flexes due to geological disturbances.

摘要： A mineral winning installation employs a longwall scraper chain conveyor at the mineral face with roof supports arranged at the goaf side of the conveyor. A winning machine, such as a shearer or plough, moves back and forth alongside the mineral face to skim or cut mineral. The machine carries its own drive means which is electrically powered and which drives a pinion, for example, meshing with a toothed rack. An independent constructional assembly arranged at the roof or floor has a multi-sectioned rail or plate carrying the toothed rack. In addition, the rail or plate supports a sealed guard housing containing an electric live track and a further sealed housing containing pressurized water. The machine has a pick-up arm which engages with a contact sliding along the electric track to supply electric power to the drive means and a conduit which has a water collector displaceable along the water housing to supply water to the machine for dust suppression.
