Abstract

Upon detection of a header slip or stall event involving one or more driven bodies of a header of a combine harvester, the header can be moved out of the crop material, and a drive system is disengaged. An auxiliary action can automatically displace a component(s) of the header to a location that can assist with clearing a blockage from the header. A driver of the drive system is automatically operated in reverse to displace the driven body(ies) in a direction that can move the blockage out of the header. The drive system can then automatically reengage, and, in connection with determining if the blockage has been cleared from the header, the driven bodies can again be driven in a direction associated with harvesting crop material. If the blockage is not cleared, a determination can be made as to whether an attempt can again be made to clear the blockage.

Claims20

Dependent claims

A system for resolving a header slip or stall event for a header of a combine harvester, the system comprising:

a driver;
a driven body positioned about the header at a location to engage a crop material, the driven body coupled to the driver such that an operation of the driver facilitates selective displacement of the driven body relative to the header;
a sensor;
and
a memory device coupled with at least one processor, the memory device including instructions that, when executed by the at least one processor, cause the at least one processor to:
determine, from at least information provided by the sensor, an occurrence of the header slip or stall event that prevents a displacement of a driven body in a first direction;
generate an auxiliary action signal to perform an auxiliary action associated with a displacement of at least one component of the header from a harvest position;
generate, after performance of the auxiliary action, a first driver signal to operate the driver to facilitate a displacement of the driven body in either the first direction or a second direction, the second direction being opposite to the first direction;
determine, after generation of the first driver signal, whether a blockage is disengaged from the header;
and
generate, in response to the determination that the blockage is disengaged from the header, a component signal to facilitate a displacement of the at least one component of the header back to the harvest position.

A method for resolving a header slip or stall event for a header of a combine harvester, the method comprising:

determining, from at least information provided by a sensor, an occurrence of the header slip or stall event that prevents a displacement of a driven body in a first direction, the driven body being selectively displaceable in the first direction or a second direction by a power transmitted from a driver, and wherein the driven body is positioned about the header at a location to engage a crop material;
generating an auxiliary action signal to perform an auxiliary action associated with a displacement of at least one component of the header from a harvest position to at least assist with a disengagement of a blockage from the header;
generating, after performance of the auxiliary action, a first driver signal to operate the driver to facilitate a displacement of the driven body in either the first direction or the second direction, the second direction being opposite to the first direction;
determining, after at least the generating of the first driver signal, whether the blockage is disengaged from the header;
and
generating, in response to determining the blockage is disengaged from the header, a component signal to facilitate a displacement of the at least one component of the header back to the harvest position.
