<p>A discharging channel (1) is supported by two arms (7, 10) lying in a vertical plane, held in rotating joint, one (10) of which is extensible to allow variability of the discharging height. The channel (1) holds a winnowing device (12) on a rotating knuckle (13), to let it reach the position of non-employ, by means of a hand traction only, on the support (16) of a splash board (17) and, with an inverse movement, to lay it as an extension of the channel (1), while the setting is stabilized by means of quick engaging hooks.</p> |
