The present invention relates to a method for controlling a height adjustment of a stripping plate of a ground milling machine, in particular a stripping plate of a cold milling machine, during the working process, said method comprising the following steps of detecting the striking of the stripping plate against an obstacle; automatically triggering the height adjustment unit for lifting the stripping plate from a working position, in which the stripping plate is in contact with the underlying ground to be processed, to avoid a further collision with the obstacle; and automatically triggering the height adjustment unit for lowering the stripping plate back to the working position upon overcoming the obstacle.

A drive apparatus in a self-propelled construction machine comprises a milling rotor and a main drive which can be coupled to the milling rotor via an engaging and disengaging clutch, and an auxiliary drive which can be coupled to the milling rotor alternatively to the main drive. The clutch is provided with a fixed side and an axially displaceable output side, which is displaceable between an engaged position and a disengaged position. The axially displaceable side is simultaneously also the engaging and disengaging part of a shiftable transmission, the fixed part of which is driven by the auxiliary drive, with the transmission and the clutch being engaged and disengaged in a selective fashion via the axially displaceable side of the clutch.

The present invention relates to methods for mounting a milling unit of a ground milling machine and to a ground milling machine comprising a mountable and dismountable milling unit.

Method for mounting a releasable milling unit to a machine frame of a ground milling machine

The present invention relates to a method for determining and monitoring the mass of the milled material removed by a ground milling machine, comprising mounting a discharge belt on the ground milling machine via a pivot bearing and a tensile connection in such a manner that it can pivot at least about a horizontal axis, determining a tensile force (F) exerted by the discharge belt to the tensile connection, calculating a mass flow (q) of the milled material removed by the ground milling machine from the measured tensile force (F) and the conveying speed of the discharge belt, and calculating the loaded mass of the milled material removed by the ground milling machine from the mass flow (q) and the loading time (t). The present invention further relates to a ground milling machine for milling off ground material, in particular a road milling machine, recycler, stabilizer or surface miner, comprising a drive motor, a milling drum mounted so it is rotatable about a rotational axis in a milling drum box, and a discharge belt for loading milled material, which is mounted on the ground milling machine via a pivot bearing and a tensile connection fixed to the discharge belt such that it can pivot at least about a horizontal axis, the ground milling machine comprising a control device, and the ground milling machine with the control device being configured to carrying out the method according to the present invention.

The invention relates to a tool device for a ground milling machine, particularly a road milling machine, a recycler, a stabilizer or a surface miner. The tool device comprises a milling chisel with a highly wear-resistant chisel tip, particularly comprising PCD material, and a chisel shaft extending along a longitudinal axis, and a chisel holder with a shaft receptacle, the chisel shaft of the milling chisel having at least one tapering section narrowing in a direction away from the chisel tip. Furthermore, a fastening device is provided, which is designed in such a way that it pulls the milling chisel along its longitudinal axis and in the direction away from the chisel tip into the shaft receptacle, the shaft receptacle of the chisel holder being designed complementary to the chisel shaft of the milling chisel in such a way that the tapering section, when braced by the fastening device, bears against the chisel holder in the shaft receptacle in a frictionally locking manner shaft receptacle. The chisel holder also comprises a base holder and a quick-change chisel holder, the base holder comprising a holder receptacle for receiving the quick-change chisel holder, and the quick-change chisel holder comprising the shaft receptacle, and the fastening device being designed in such a way that it pulls both the milling chisel along its longitudinal axis and in the direction away from the chisel tip into the shaft receptacle as well as the quick-change chisel holder into the holder receptacle in the base holder. The invention also relates to a milling chisel and a quick-change chisel holder for such a tool device and a ground milling machine with such a tool device.

The present invention relates to a ground milling machine, particularly a road milling machine, comprising a machine frame supported by travelling devices, a drive engine and a milling device arranged in a milling drum box, the milling drum box comprising a stripping plate which is height-adjustable by means of at least a first and a second actuator. Further, the present invention relates to a method for adjusting a stripping plate of a milling drum box of a ground milling machine, particularly a road milling machine. For the purpose of a reliable adjustment of the stripping plate, the present invention proposes using a monitoring device for detecting the adjustment of a first actuator and a control device for controlling the adjustment of a second actuator depending on the adjustment of the first actuator.

Ground milling machine and method for adjusting the stripping plate of a ground milling machine

The present invention relates to a ground milling machine, in particular, a road cold milling machine, having a replaceable milling drum unit. To make this replacement procedure easier, the present invention proposes a fastening device between the milling part and the machine part of the ground milling machine. The present invention furthermore relates to a method for replacing a milling part on the ground milling machine, a fastening device being used for this purpose.
