<p>The invention relates to an adjustment device for a roof cutter holder arranged height-adjustably on the plough body of a winning plough, with a worm wheel (6) for interacting with a rack-like toothing on the roof cutter holder, with an input shaft (8) for actuating the worm wheel, preferably with a gear unit (9) interposed between the input shaft and the worm wheel, and with a head plate (1) which has a passage (18) for the input shaft and which can be fastened or is fastened fixedly in terms of rotation on the plough body (1). To make it possible to mount and release the roof cutter holder adjustment device in a simple manner, the head plate (1) comprises at least one fastening device to which a securing element (21), which can be plugged onto the free end of the input shaft, can be fastened fixedly in terms of rotation in the mounted state.</p> |
