Arrangement for the exchange of can feel wheels on a can feel the vehicle

摘要

An arrangement (1) for changing a can feel wheel (2) on a can feel the vehicle (4) for the removal of soil samples, with a fork-shaped holding device (6), in which the spürrad (2) is received by a linkage (8) by means of a motor, first lowered sampling position can be pivoted into a second detection position in which the contamination adhering to spürrad (2) by a sensor (10) can be detected, wherein the fork-shaped holding device (6) a first and second holding arm (6a, 6b), consisting of a first together driven working position, in which the spürrad (2) between the retaining arms is rotatably mounted, into a second release position and spread apart in which the spürrad (2) of the support arms can be seen from, comprises a support device (12) with an expanding element (14), which by means of a first actuator (16) from a rest position, in which the expanding element (14) outside the path of movement of the holding device (6) is located, is movable in a second spürradwechselposition, in which the expanding element (14) with the first and second holding arm (6a, 6b) and the latter comes into contact in an intermediate position is spread open, in which the spürrad (2) with its axis of rotation (16) in the manner between the retaining arms (6a, 6b) is held, that this by applying an external pressure force of the retaining arms (6a, 6b) is removable, as well as a receiving device (18), in which a new spürrad (2n) can be accommodated, which is formed by means of a second actuator (20) for the generation of the external force against the material to changing spürrad (2a) is movable, in order to achieve this in the intermediate position between the retaining arms (6a, 6b) to press out and the new spürrad (2n), subsequently, with its axis of rotation (17) between the holding arms (6a, 6b) to move.
