Abstract
A combine harvester has an inclination module coupled to the straw walker control system. The inclination module provides information on the inclination of the combine harvester. The straw walker control system is further configured to control the controllable frequency of the oscillating movement in function of the information on the inclination of the combine harvester.
Claims14
A combine harvester comprising:
- a straw walker;
- a straw walker drive system connected to the straw walker and configured to drive the straw walker with an oscillating movement at a controllable frequency;
- and
- a straw walker control system connected to the straw walker drive system and configured to control the controllable frequency of the oscillating movement,
- an inclination module coupled to the straw walker control system, the inclination module configured to provide information on an inclination of the combine harvester;
- the straw walker control system further comprising a configuration module comprising a predetermined correlation between the controllable frequency of the oscillating movement and the information on the inclination of the combine harvester, the straw walker control system further configured to control the controllable frequency of the oscillating movement as a function of the information on the inclination of the combine harvester by the predetermined correlation;
- wherein the predetermined correlation comprises:
- a first value of the information on inclination, and
- a second value of the information on inclination relating to an inclination higher than the inclination related to the first value, a rate of change of the controllable frequencies correlated to the first value is being lower than a rate of change of the controllable frequency correlated to the second value.

A method for operating a combine harvester comprising the steps of:
- receiving with a straw walker control system an input signal representative of information on an inclination of the combine harvester provided by the inclination module;
- calculating an output signal with the straw walker control system by processing the input signal by a predetermined correlation between a controllable frequency of a oscillating movement and the information on the inclination of the combine harvester, wherein the predetermined correlation comprises a first value of the information on inclination, and a second value of the information on inclination which relates to an inclination that is higher than the inclination related to the first value, a rate of change of the controllable frequencies correlated to the first value being lower than a rate of change of the controllable frequency correlated to the second value;
- and
- providing with the straw walker control system the output signal for controlling the controllable frequency of the oscillating movement, the straw walker control system connected to a straw walker drive system of a straw walker and the drive system connected to and configured to drive the straw walker with the oscillating movement at the controllable frequency.
