A method of determining crop parameters in an agricultural harvester has the steps of determining at least one crop parameter during a working process with a compacting device which is fillable with a crop probe, and using for determining the at least one crop parameter of the crop probe depending on at least one defined compression of the crop probe produced by the compacting device.

Method of and device for determining crop parameters

Chain conveyors in an agricultural harvesting machine can be tensioned by means of a tension adjusting device including an adjusting unit which is coupled to a displaceable shaft via a linkage means or connector members. The adjusting units are advantageously hydraulic cylinders controlled in synchronism. The hydraulic cylinders can be mutually independently pressurized via bypass lines incorporating control valves.

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 surface of the control cam. The forage harvester is particularly suitable for harvesting and chopping fast-growing woody plants.
