Abstract

The invention relates to a ground milling machine, in particular a road milling machine, finishing machine, stabilizer or surface mining machine, said ground milling machine having: a milling roller; a milling roller box with a scraping device, The scraping device forms the rear wall of the milling roller box in the working direction and is pivotable between a working position in which the scraping device closes the milling roller box and a maintenance position in which the scraping device closes the milling roller box. In the position, the scraping device opens the access to the inner cavity of the milling roller box; the locking device, the locking device can releasably fix the scraping device in the maintenance position; and the operating element, after manually operating the operating element, The locking device releases the scraper device again, wherein an operating element for actuating the locking device is provided on two opposite longitudinal sides of the ground milling machine.

Description

technical field [0001] The invention relates to a ground milling machine, in particular a road milling machine, finishing machine, stabilizer or surface mining machine. Ground milling machines of this type are often used for road and street construction or for resource extraction and for loosening and / or crushing and / or mixing ground foundations. Background technique [0002] This type of ground milling machine has a frame, multiple crawlers, a drive motor, usually an internal combustion engine, a driver's station, milling rollers in a milling roller box and usually also a discharge for carrying away the milled material bring. The milling roller is equipped with a plurality of cutter devices, which are pushed into the ground to be milled by the rotational movement of the milling roller during the working mode of the ground milling machine, whereby the ground is turned over loose. In order to leave a uniform and orderly milling machine behind the ground milling machine aft...
