FIELD: agriculture.
SUBSTANCE: invention refers to agricultural machinery industry and can be used in the cutting devices. The drive mechanism contains the case where drive and driven eccentric shafts are located. Both shafts are installed on two bearings and have cogwheels of conic transfer. There is a toggle with a finger made in the form of one detail located on the drive shaft. The toggle has a pinion-ring gear of epicyclical train. Fixing of conic transfer is executed in the form of rigid fixing of each conic cogwheel from bilateral axial moving according to the case. The ring gears of conic wheels are located near to the basic bearings rigidly fixed in the case. There is a system with the compensatory channel that supplies greasing to mobile elements of the drive mechanism.
EFFECT: construction of knife drive mechanism provides high reliability of its work.
