Abstract
A method for analyzing the operating state of a cutting device for mowing crop, the cutting device having at least one mowing knife having cutting edges which interact with counter cutting edges of the cutting device, including: detecting of a signal representing the stroke position of the mowing knife; detecting a signal representing the knife force for driving the mowing knife as a function of the stroke position, and determining crop and/or cutting system properties on the basis of an evaluation of the signal representing the knife force as a function of the stroke position.
Claims11
A method for analyzing the operating state of a cutting device for mowing crop, the cutting device having at least one mowing knife which is driven in reciprocating manner in a stroke direction H, and the mowing knife having cutting edges which interact with counter cutting edges of the cutting device, with the following method steps:
- detecting of a signal representing the stroke position of the mowing knife,
- detecting a signal representing a knife force for driving the mowing knife as a function of the stroke position, and
- determining crop and/or cutting device properties on the basis of an evaluation of the signal representing the knife force as a function of the stroke position.
A cutting device for an agricultural harvesting machine for mowing crop, comprising
- at least one mowing knife driven in reciprocating manner in a stroke direction,
- a drive driving the mowing knife,
- a sensor for detecting a signal representing the stroke position of the mowing knife,
- a sensor for detecting a signal which represents a knife force for driving the mowing knife, and
- a processing unit for evaluating and recording the detected signals.
