Abstract
A device for treating soils or road surfaces includes a machine frame (1) carrying a working roll (4) in a working roll housing (8) defining a working space (6). The roll housing (8) is provided with a spraying mechanism (10) for binder or water having at least one outlet nozzle (12) opening directly into the working space (6). A controllable closing device (18) has a closing element (22) which, in an open position, unblocks the outlet nozzle (12) and in a first closed position, closes the outlet nozzle (12). The closing device (18) is capable of triggering an additional movement of the closing element (22) beyond the first closing position such that at a second closed position, material accumulations in and/or beyond the outlet nozzle (12) are removed.
