Abstract

A method for changing throughgoing openings on separation area of a concave in an agricultural harvester in which the concave is composed of at least one frame, a plurality of beater strips and wires together forming the concave separating area, arranging at least one adjusting device under the concave separating area, and adjusting a width of the throughgoing openings by the at least one adjusting device; and a device for performing the method is provided.

Claims

1. A method for changing throughgoing openings in a separation area of a concave in an agricultural harvester in which the concave is composed of at least one frame, a plurality of beater strips and wires together forming the concave separating area, the method comprising the steps of arranging at least one adjusting device under the concave separating area;

and adjusting a width of the throughgoing openings by the at least one adjusting device.

2. A method as defined in claim 1;

and further comprising guiding the adjusting device from below between the wires of the concave.

3. A method as defined in claim 1;

and further comprising guiding an adjusting device between the wires in a direction selected from the group consisting laterally, outwards and both.

4. A method as defined in claim 1;

and further comprising bringing back the adjusting device to its initial position in a direction selected from the group consisting downwardly, laterally, and both.
