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 actuator mechanism for the cutting knife assembly of an agricultural implement applied, for example, to a grain harvester or harvester, which has been designed to allow the circulation of lubricating fluid within it and In this way, obtain adequate cooling of the bearing region and, consequently, increase the service life of the actuating mechanisms. more particularly, the present actuator mechanism comprises a housing (18) with lid (22) internally accommodating the knife assembly (13) movement mechanisms, including a drive member assembly (19) and the lubricating fluid. said cover (22) is provided with bearings (29) for positioning drive pivots (28) through the respective bearings (34) to obtain a bearing region, said bearings (29) are configured with the arranging at least one channel (31) connecting the upper portion (33) of the bearing region with the interior of said housing (18).
