actuator mechanism for the cutting knife set of an agricultural implement and agricultural implement for cutting and harvesting grain

摘要

The present invention relates to a novel actuating mechanism for the cutting knife assembly of an agricultural implement applied, for example, to a grain harvester or harvester, which is designed to eliminate any vertical displacements of the drive pivots and thereby This way, avoid creating gaps in the sealing elements, thereby increasing the life of the actuator mechanisms. more particularly, the present actuator mechanism comprises a housing (18) with a cap (22) internally accommodating the knife assembly (13) movement mechanisms, including a drive element assembly (19) and a lubricating fluid. the cover (22) is provided with bearings (29) designed to accommodate the drive pivot (28) with support (27) which is supported by a support rod (31) attached to said cover (22), whereby in the lower region of said support (27) is fixed a washer (33) supported next to the support rod (31), in order to restrict the vertical movement of said actuating pivot.
