1. A cutting device for cutting agricultural crop plants, the cutting device comprising:
a knife element;
a radial conveying element stationary relative to the knife element;
wherein the cutting device is configured to rotate in a circulating direction about a cutting rotation axis for cutting the agricultural crop plants;
wherein, in a plan view of a first top side of the cutting device, the knife element is embodied open in the circulating direction;
wherein the radial conveying element is arranged at the first top side of the cutting device and is configured, at least in sections thereof, to convey the agricultural crop plants in a conveying direction that is oriented, relative to the cutting rotation axis, partly tangentially and partly radially in a radial direction in relation to the cutting rotation axis;
wherein the radial conveying element is a first corrugated monolithic region of the cutting device, wherein the first corrugated monolithic region starts from a region of a medium height of the cutting device;
the cutting device further comprising an intermediate element, wherein the radial conveying element comprises a conveying contour and adjoins the intermediate element along the conveying contour, wherein the intermediate element is arranged upstream of the radial conveying element in the circulating direction, wherein the conveying contour comprises a neutral conveying point and a conveying section that extends away from the neutral conveying point partly in the circulating direction and partly in the radial direction away from the cutting rotation axis;
wherein the conveying contour comprises a discharge section and the discharge section extends partly opposite to the circulating direction and partly in the radial direction away from the cutting rotation axis, wherein the discharge section is arranged between the cutting rotation axis and the conveying section.
