Electromechanical actuating device for the concave of a combine harvester

摘要

The invention relates to an electromechanical actuating device for the concave of a combine harvester, having a fine-adjustment device and a means for rapid lowering of the concave. The essential features of the invention consist in the fact that there is arranged, in the adjustment linkage, an electric lifting-spindle motor (18), of which the piston rod (20) is provided with a guide bolt (21) which is arranged in a sliding manner within a slot guide (22) of an actuating segment (23). The actuating segment (23) is connected in a rotationally fixed manner to an adjustment shaft (24) which is in connection with the concave (1) via a connecting linkage. <IMAGE>
