Abstract
A sampling device for inspection vehicles equipped with an environmental inspection system, the system comprising an analyzer having a receiving head (21), to which the substances to be examined are supplied by means of a movable collecting body (4) having a ground-engageable contact surface. The collecting body is formed by a rope-like material (4) which is wound up on a supply drum (2) and passed between two rollers (10, 11) arranged at a certain distance therefrom. By displacing the material (4) in its longitudinal direction, the material can be moved into a first position in which an end section (41) of the material hangs down and contacts the ground (42), and a second position in which the end section (41), which had been in contact with the ground (42), is positioned opposite the receiving head (21). Consumed end portions (41) can be cut off by means of a separating device.
