ABSTRACT:
A sediment collecting device is provided which includes a collection body positioned adjacent the floor of a liquid-containing vessel. The collection body moves across the vessel floor along a fixed track in a stepping manner. A suction pipe or, alternatively, a scraping mechanism is integrally joined to the collection body for collecting sediment as the collection body is driven. The collection body is capable of reciprocating movement along the track and includes first, second and third body members. When the collection body is driven by means of pressurized fluid applied in a predetermined manner to cylinders fastened to the second body member, at least one body member is moved relative to at least another one of the remaining two body members.
