FIELD: agriculture. ^ SUBSTANCE: breaking machine comprises a feed conveyor, a flattening pair of rollers, a breaking unit, comprising working links of chain conveyors with holders fixed on them, every of which has two movable riffles, limiters of riffle stands movement, breaking sprockets, disk supports, ties, master sprockets. Riffle holders fixed with ties are symmetrically attached on each of external plates of opposite links of two chain conveyors, moreover, riffle stands may freely move relative to holders. To avoid collision of riffles of upper and lower chain conveyors in a jaw of two chain conveyors parallel in the horizontal plane, the upper one contains limiters of riffle movement. Serial embedding of riffles is ensured with disk supports. ^ EFFECT: improved efficiency of stem wood and its fibrous part separation with lower damage of the latter and reduced power inputs. ^ 7 cl, 4 dwg |
