<p>Conveyor bar driving device that comprises a drive lever (8), couplable in articulated manner by its upper end (20a) to the conveyor bar (2), a rotation axis (9), around which said drive lever rotates; a support structure (11), whereto the rotation axis of the drive lever is joined; and a means to produce, simultaneous to the rotary movement of the drive lever around its rotation axis, a relative movement between said rotation axis and the support structure in such a way that when said drive lever rotates around the rotation axis, in either direction, a corresponding forward or backward movement, respectively, following a straight-line trajectory is transmitted to the upper end of the drive lever.</p> |
