Abstract

A conveying device for stem-bearing crops which is provided with two rotatable circular blades and two rotatable housings above for receiving tines, is to be designed in such a way that the tines are fixed to the rotatable housing in such a way that the risk of breaking is substantially reduced, so that the service life of the tines is substantially increased. The tines are permanently inserted in bearing plates. Each bearing plate is mounted freely rotatably on a fixed bearing pin, the longitudinal center axis of the bearing pin being parallel to and spaced apart from the axis of rotation of the cylindrical housing. On the bearing plate on the outside on two bolts are mounted roller bearings which roll over the control face of a control cam which is also mounted on the bearing pin. The control cam is not rotatable relative to the bearing pin, but slidable in the axial direction, and is pressed by a plate spring assembly toward the roller bearings. As soon as an elevated torque acts on a tine, it is rotated in a direction opposite the direction of rotation, the compressive force of the plate spring assembly being increased, as the roller bearings roll over an ascending oblique surf…
