Abstract:
A cutting device for agricultural harvesting machines, comprising:a conveyor channel, in which a number of cutting blades mounted in rotatable fashion, arranged at least in a single row and protruding into the conveyor channel in a cutting position interact with a driven rotating conveyor mechanism equipped with conveying prongs and aligned along a horizontal axis crosswise to the travel and work direction for the purpose of cutting stalk products, a support mechanism providing elastic support to each individual cutting blade in the cutting position, a control device for releasing the support mechanism and thereby allowing all or a number of cutting blades to rotate into a non-cutting position, and a support and control member mounted in rotatable fashion and aligned about an axis parallel to a rotation axis of the corresponding cutting blade assigned to each cutting blade for the purpose of providing elastic support to each individual cutting blade in the cutting position and for allowing the cutting blade to rotate out of the cutting position into the non-cutting position, the support and control members being mounted in rotatable fashion to a control shaft aligned crosswise to the travel direction, each individual support and control member being elastically connected to the control shaft by an energy accumulator.
