Patent attributes
The combine harvester includes a harvest frame that receives grain culms cut by a reaping device and a rake-in auger disposed within the harvest frame so as to be rotatable about a rotary axis extending in a right/left direction of the harvester body. The rake-in auger conveys the grain culms inside the harvest frame in a right/left direction of the harvester body and rakes in the grain culms toward the rear of the harvester body. The combine harvester further includes a feeder that is communicatively connected to a rear wall of the harvest frame, and that conveys the grain culms raked in by the rake-in auger toward the rear of the harvester body. A grain culm sensor that detects the presence of the grain culms when coming in contact with the grain culms is disposed at a grain culm feed port in the feeder.
