<p>The object of the invention is a tank construction in a bulk cargo transportation system consisting of a lorry (16) and trailer (1), in which revolving cylindrical tanks (3, 19) equipped with parallel interior spirals (9) are supported on the chassis (2, 20) of the lorry and trailer. The tanks are arranged to be placed sequentially by pushing the long cone of the first tank into the larger opening of the second tank, when by rotating the tanks (3, 19) the bulk cargo moves from the first tank to the second. According to the invention, the longer part of the cone compared to the cone of the second tank (19) is formed as an interchangeable point (10) to be attached to or removed from the conical end (6), which point is adapted to be alternatively attached to the opposite conical end (15) in the other tank (19), and which tank construction includes locking elements (11) to lock the interchangeable point (10) to the conical end (6) and that the interior of the interchangeable point (10) includes a spiral (18) running in the same direction as the spiral (9) inside the tank (3) and that close to the opening the spiral (9) of the tank (3, 19) is low in order to permit penetration by the interchangeable point (10).</p> |
