A combine including a grain tank that retains grain conveyed from a threshing device; a discharge auger; a temporary retention unit within the grain tank that temporarily retains part of the grain and has a discharge port; a quality measurement unit that detects quality of the grain retained in the temporary retention unit; a shutter transitionable between a position where the discharge port is open and a position where the discharge port is closed; a control unit that opens the shutter when the measurement by the quality measurement unit is completed and closes the shutter when all of the grain in the temporary retention unit is discharged; a volume measurement unit that detects the retention volume of the grain retained in the grain tank; and a determination unit that determines whether the retention volume exceeds a predetermined value, and if so, the control unit stops the opening/closing control.

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.

An agricultural crop harvester () includes a tank in which harvested crops are stored, a stored amount calculation section () that calculates a current stored amount of harvested crops stored in the tank, a communication section () which receives drier operation information indicative of a drier operational status transmitted from a drying facility, a work management sectionthat determines completion timing of a harvesting work based on the current stored amount and the drier operation information, and a notification sectionwhich notifies the completion timing.

A combine including: a measurement sensor that measures a retention volume amount of a grain retained in a grain tank; a determination unit that determines whether or not the retention volume amount measured by the measurement sensor exceeds a preset threshold; a notification unit that, if it is determined by the determination unit that the retention volume amount exceeds the threshold, notifies an operator of information indicating that the amount of the grain exceeds the threshold; a change unit that can change the threshold; and a communication unit that communicates with an external server. The change unit changes the threshold based on data received from the external server.

Combine

A combine that can accurately measure the weight of grain retained in a grain tank is provided. When a weight measurement signal is output from a measurement switch, a weight measurement decision unitinstructs a working state determination unitto perform working state determination. If it is determined that the combine is in the working state, the weight measurement decision unitdoes not instruct a load cellto perform weight measurement.
