Claim 14:
15. A mobile earth working machine in a reference state ready for earth-working operation, comprising:
a machine frame;
a plurality of ground engaging drive units connected to the machine frame for moving the earth working machine across a ground surface;
a milling drum supported from the machine frame and configured to remove material from a region of a substrate;
a substrate material conveyor;
a pivot joint arrangement arranged functionally between the machine frame and the substrate material conveyor, the pivot joint arrangement including a frame-associated joint element connected to the machine frame immovably relative to the machine frame, and the pivot joint arrangement including a conveyor-associated joint element connected to the substrate material conveyor, the conveyor-associated joint element being pivotably connected to the frame-associated joint element by a pivot joint such that the conveyor-associated joint element is pivotable around a pivot axis relative to the frame-associated joint element;
a mechanical coupling arranged functionally between the machine frame and the substrate material conveyor, the mechanical coupling being configured to detachably couple the substrate material conveyor to the machine frame, the mechanical coupling including a frame-side coupling configuration connected to the machine frame and a conveyor-side counterpart coupling configuration connected to the substrate material conveyor, the mechanical coupling being spaced from the pivot joint; and
a lock movable between a locking state securing the substrate material conveyor coupled to the machine frame against detachment from the machine frame, and a release state permitting detachment of the substrate material conveyor from the machine frame;
wherein:
the lock includes at least one displaceable locking member mounted displaceably on one of the frame side coupling configuration and the conveyor-side counterpart coupling configuration, and the lock includes a securing configuration mounted on the other of the frame side coupling configuration and the conveyor-side counterpart coupling configuration, wherein the displaceable locking member engages behind or passes through the securing configuration when the displaceable locking member is displaced to lock the substrate material conveyor to the machine frame;
the one of the frame side coupling configuration and the conveyor-side counterpart coupling configuration on which the displaceable locking member is mounted includes a guide configured such that the displaceable locking member engages behind or passes through the guide when the displaceable locking member engages behind or passes through the securing configuration.
