Title
(EN) ROTARY FLAIL FEEDING DEVICE
(FR) ALIMENTATION D'UNE DEBROUISSAILLEUSE A FIL
Abstract
(EN)
A rotary flail feeding device includes a head (12) having an annular line storage cavity (46), a central post (34) and an annular line feeding passage (78) extending radially inwardly from the cavity to an annular outlet opening (76) at the end of the post. A coil of flail line is wound in the cavity and extends inwardly through the passage, around the post and out the opening. The device automatically relengthens shortened flails.
(FR)
L'invention porte sur le système d'alimentation d'une débrousailleuse à fil comportant: une tête (12) munie d'une cavité de stockage annulaire du fil (46); un axe central (34); et un conduit d'alimentation (78) reliant radialement le centre de la cavité (46) à une ouverture annulaire de sortie (76) située à l'extrémité de l'axe. Le fil bobiné dans la cavité emprunte le passage en se dirigeant vers l'intérieur, contourne l'axe, puis sort vers l'extérieur par l'ouverture. Le système compense automatiquement les fils raccourcis.
