Title (EN) A MACHINE FOR LIMBING TREES AND STEMS
(FR) MACHINE D"EBRANCHAGE DES ARBRES ET DES TRONCS
Abstract:
(EN) A machine for limbing trees and stems comprises a holding device (7) for holding the tree or stem during a limbing operation, said holding device being arranged on a stationary first frame structure (1, 2, 3); a limbing device (13) for limbing the tree or stem held by the holding device (7), said limbing device being arranged on a second frame structure (4, 5, 6) which is movable relative to the first frame structure (1, 2, 3); and a drive means (8) for moving the second frame structure (4, 5, 6) backwards and forwards relative to the first frame structure (1, 2, 3). For the purpose of reducing the amount of power required to operate the machine, the limbing device (13) is arranged, during the reciprocatory movement of the second frame structure (4, 5, 6) to be moved forwards and backwards along said second frame structure (4, 5, 6) by means of at least one chain or line (28) which passes over guide rollers (26, 27) arranged on the second frame structure (4, 5, 6), said chain or line being attached to the limbing device (13) and either to the first frame structure (1, 2, 3) or to a location which is fixed relative to said first frame structure in a manner such that the limbing device (13) moves twice as far as the second frame structure relative to the first frame structure during the reciprocatory movement of said second frame structure.
(FR) Une machine d"ebranchage des arbres et des troncs comprend un dispositif de support (7) pour tenir l"arbre ou le tronc pendant l"operation d"ebranchage, ledit dispositif de support etant dispose sur un premier chassis fixe (1, 2, 3), un dispositif d"ebranchage (13) pour ebrancher l"arbre ou le tronc tenu par le dispositif de support (7), ledit dispositif etant dispose sur un second chassis (4, 5, 6) mobile par rapport au premier chassis (1, 2, 3), et des moyens d"entrainement (8) pour deplacer le second chassis (4, 5, 6) en avant et en arriere par rapport au premier chassis (1, 2, 3). Dans le but de reduire la quantite d"energie requise pour faire fonctionner la machine, le dispositif d"ebranchage (13) est dispose de sorte que, pendant le mouvement alternatif du second chassis (4, 5, 6), ce dispositif d"ebranchage (13) se deplace en avant et en arriere le long de ce second chassis (4, 5, 6) au moyen d"au moins une chaine ou ligne (28) qui passe sur des rou- leaux de guidage (26, 27) disposes sur le second chassis (4, 5, 6), ladite chaine ou ligne etant attachee au dispositif d"ebranchage (13) et soit au premier chassis (1, 2, 3) soit a un endroit fixe par rapport audit premier chassis de telle maniere que le dispositif d"ebranchage (13) se deplace deux fois plus loin que le second chassis par rapport au premier chassis pendant le mouvement alternatif du second chassis.
