<p>The machine comprises at least two sets of lifting discs (2A, 2B) mounted side by side on the back of a transverse support (1, 10). The discs in each set are all inclined in the same way, either to the left for the first set (2A) or to the right for the second set (2B), in both cases making an acute angle with the forward direction of the machine (the axis 6). These lifting components cooperate with a set of devices for picking up and cleaning which consist of several rows of turbines. The plane of rotation of the turbines (20) in the first row is inclined in the longitudinal direction with respect to the plane of rotation of the turbines (24, 28) in the following rows. <IMAGE></p> |
