Abstract

An apparatus for processing ground surfaces comprises a moving device, a working device, especially a milling device for milling the ground surface, and a drive device for driving the moving device and the working device, wherein the working device is movable between a working position, in which it is in operative engagement with the ground surface, and a maneuvering position, in which it is not in operative engagement with the ground surface, wherein a sensor device is provided which detects the maneuvering position and / or at least one working parameter of the working device, namely its power consumption, working speed, rotational speed or its inclination, and / or at least one load parameter of the moving device, and a control device which reduces the frictional connection between the drive device and the working device and / or the drive power transmitted by the drive device to the working device in the maneuvering position and / or in case of the detection of a deviation of the at least one detected working parameter or load parameter from a set parameter value.

Description

Technical field

[0001] The invention relates to a device for processing the ground. Background technique

[0002] Such a mobile construction machine for surface treatment is known from EP1408158B1.

[0003] The road milling machine described therein includes a frame with a drive motor for driving the moving device and for driving the working device. The movement device may include wheels or guide components connected to the frame through a lifting column.

[0004] As a roller drive, the drive device is particularly intended to drive a milling drum for milling the ground, preferably operating in a reverse operation. The milling drum can be disconnected from the drive system by a coupling device. In the direction of travel, a scraper is arranged behind the milling drum in a height-adjustable manner, wherein the scraper slides over the ground surface that has been milled by the milling drum or the ground surface to be milled by the milling drum. During the milling operation, the bot...

Embodiment Construction

[0041] Such as figure 1 The equipment or construction machine 1 for processing the ground shown in FIG. 1 includes a frame 3 and a driving device 6. The driving device 6 is used to drive the moving device 2 and the working device 4, in this example the working device is a milling device. In this embodiment, the movement device 2 is composed of wheels. The milling device 4 can be separated from the driving device 6 by means of a coupling device (not shown), and can be brought into a lifting position (not shown) by means of a lifting device 5 on the frame 3.

[0042] The lowered position shown here corresponds to the working position or the working stroke of milling the ground surface 13 shown. As shown in the figure, during the working stroke, the rotation direction of the working device 4 is opposite to the movement direction of the equipment 1 or the rotation direction of the wheel 2. In the raised position or the maneuvering position (not shown), the working device 4 is no lo...
