Abstract
For controlling a threshing mechanism of a combine harvester parameters of the threshing mechanism are adjusted with respect to a nominal crop throughput determined for corresponding harvesting conditions to an optimal value, the changing automatically and the adjustment includes automatically determining a deviation of an actual crop throughput from the nominal crop throughput, and adjusting at least one threshing mechanism parameter for adaptation to the actual crop throughput; also a combine harvester with the control device for performing the method is proposed.
Claims19
A method of controlling a threshing mechanism of a combine harvester, comprising the steps of adjusting parameters of the threshing mechanism with respect to a nominal crop throughput determined for corresponding harvesting conditions to an optimal value, said adjusting including automatically determining a deviation of an actual crop throughput as an input value at a beginning of a harvesting process from the nominal crop throughput, and adjusting at least one threshing mechanism parameter for adaptation to the actual crop throughput only when the deviation occurs.
A method as defined in claim 13;
- and further comprising, after elapsing a predetermined second time period in which the nominal crop throughput is not reached or deviates more than a predetermined threshold value, performing an action selected from the group consisting of automatically performing a new adjustment of further adjustable parameters by different working elements of the combine harvester, suggesting to an operator to adjust these adjustable parameters optimally with respect to the actual crop throughput as a new nominal crop throughput, and both.
A method of controlling a threshing mechanism of a combine harvester, comprising the steps of adjusting parameters of the threshing mechanism with respect to a nominal crop throughput determined for corresponding harvesting conditions to an optimal value, said adjusting including automatically determining a deviation of an actual crop throughput as an input value at a beginning of a harvesting process from the nominal crop throughput, and adjusting at least one threshing mechanism parameter for adaptation to the actual crop throughput only when the deviation occurs, wherein said adjusting a threshing mechanism parameter includes performing the adjusting when a situation occurs selected from the group consisting of a deviation of the actual crop throughput by a predetermined threshold value, a deviation of a predetermined first time period, and both from the nominal crop throughput.
A combine harvester, comprising a threshing mechanism, and a control device for adjusting parameters of said threshing mechanism with respect to a nominal crop throughput determined for crop conditions to an optimal value, said control device having a crop throughput control unit which automatically recognizes a deviation of an actual crop throughput as an input value at a beginning of a harvesting process from the nominal crop throughput, said control device being formed so that only in the case of such a deviation it adjusts at least one threshing mechanism parameter for adapting to the actual crop throughput.
