摘要:
summary “hay-making machine with a coupling device containing an improved return device”. the present invention relates to a hay machine comprising a chassis (2) supported on the ground by wheels (6) and a working device (11) connected to the chassis (2), the chassis (2) comprising a coupling device ( 4) to which two coupling parts (18a, 18b) are attached, each carrying a trunnion (17a, 17b) for coupling to the respective lower arms of a tractor (5), each coupling part (18a, 18b) cooperating with a respective return device (21a, 21b), each return device (21a, 21b) storing energy when the corresponding journal (17a, 17b) moves, relative to the coupling device (4), upwards, from a first position, and each return device (21a, 21b) being able to return this energy to the corresponding trunnion (17a, 17b) by bringing the trunnion (17a, 17b) back to the first position. the invention is remarkable with respect to the fact that each return device (21a, 21b) stores energy when the corresponding trunnion (17a, 17b) moves, relative to the coupling device (4), downwards, from a second position, and because each return device (21a, 21b) can return this energy to the corresponding trunnion (17a, 17b), by bringing the trunnion (17a, 17b) back to the second position. 1/1resumo “máquina de fenação com um dispositivo de engate contendo um dispositivo de retorno aperfeiçoado”. a presente invenção se refere a uma máquina de fenação compreendendo um chassi (2) apoiado ao solo por rodas (6) e um dispositivo de trabalho (11) ligado ao chassi (2), o chassi (2) comportando um dispositivo de engate (4) ao qual são articuladas duas peças de engate (18a, 18b) carregando cada uma delas um munhão (17a, 17b) para o acoplamento nos respectivos braços inferiores de um trator (5), cada peça de engate (18a, 18b) cooperando com um respectivo dispositivo de retorno (21a, 21b), cada dispositivo de retorno (21a, 21b) armazenando energia quando o correspondente munhão (17a, 17b) se desloca, relativamente
