Abstract

L'invenzione riguarda un braccio escavatore longitudinale per scavi ed abbattimenti, del tipo utilizzato in macchine escavatrici parziali, e simili. Secondo l'invenzione, la testa fresatrice (6) è montata per mezzo di un manicotto posteriore rotante (15) e per mezzo di cuscinetti (16, 17) sul portatesta (2) che è fissato al braccio escavatore (1) ed attraverso il quale passa l'albero d'azionamento (7), mentre, in una forma esecutiva preferita dell'invenzione, il manicotto rotante (15) costituisce nel contempo anche il sopporto di una coclea trasportatrice (24). Il sopporto della testa fresatrice (6) e del suo albero d'azionamento (7) avviene pertanto non per mezzo di cuscinetti a rotolamento associati all'albero, bensì per mezzo di cuscinetti disposti sul portatesta (2) che sostiene la testa fresatrice (6) per mezzo del manicotto rotante (15) collegato saldamente con la detta testa stessa.The invention relates to a longitudinal excavator arm for excavation and felling, of the type used in partial excavating machines, and the like. According to the invention, the milling head (6) is mounted by means of a rotating rear sleeve (15) and by means of bearings (16, 17) on the head-holder (2) which is fixed to the excavator arm (1) and through the which passes the drive shaft (7), while, in a preferred embodiment of the invention, the rotating sleeve (15) also constitutes at the same time the support of a conveyor screw (24). The support of the milling head (6) and its drive shaft (7) therefore takes place not by means of rolling bearings associated with the shaft, but by means of bearings arranged on the head-holder (2) which supports the milling head (6 ) by means of the rotating sleeve (15) firmly connected with said head itself.
