A combine harvester includes a conveyance mechanism for conveying grains obtained by a thresher for threshing grain culms reaped from a field to a grain tank, a measurer () for measuring the amount of grain conveyed to the grain tank as a conveyed yield, a yield assignment calculator () for calculating a minimal section yield, which is a yield per minimal section, by assigning the conveyed yield to a minimal section in the field, a grain conveyance state detector () for detecting a grain conveyance state of the conveyance mechanism (), a yield corrector () for correcting the minimal section yield in accordance with the grain conveyance state, and a yield distribution data generator () for generating yield distribution data that represents a yield distribution in the field, based on the minimal section yield.

Combine harvester comprising yield corrector for correcting minimal section yield

A combine harvester includes: a grain conveyance mechanism for conveying grains from a threshing apparatus to a grain tank; a grain discharge apparatus provided in an end area of the grain conveyance mechanism, the grain discharge apparatus having a discharge case provided with a grain discharge opening, and a discharge rotor rotatably arranged in the discharge case; a pressed portion that is subjected to a pressing force applied by grains immediately before the grains are discharged by the discharge rotor; a load detector for detecting the pressing force exerted on the pressed portion; and a yield evaluator for evaluating the amount of conveyed grain based on a detection signal from the load detector.

Combine harvester and grain yield management system for combine harvester

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.

A grain management system includes a combine and a management server. The combine includes a grain measurer for outputting a measured value related to a component of harvested grains supplied to a grain tank, and a data transmitter for transmitting the measured value and field identification information for specifying the field to the management server via a communication line. The management server includes a receiver for receiving the field identification information and the measured value from the combine, a table manager for determining a measured value-grain component value table for deriving a grain component value using the measured value based on the field identification information, and a grain component value computer for obtaining the grain component value based on the measured value, using the measured value-grain component value table that is determined by the table manager.

Grain management system and combine

A combine for reaping culms in a field while traveling, and accumulating, in a grain tank, grains obtained by threshing reaped culms, includes: a yield calculator for calculating a yield per unit of travel, which is a yield per unit of travel distance; a work travel determinerfor determining non-harvest work travel that does not involve grain harvesting, and harvest work travel that involves grain harvesting; a harvest map data generatorfor generating harvest map data in which the yield per unit of travel, a travel route on which the combine has traveled in a field, and a result of determination performed by the work travel determiner are associated with one another; and a harvest information recorder for recording the harvest map data.

Combine and grain evaluation control apparatus for combine

A harvesting machine includes: a crop tank; a measuring device that measures an amount of crop that has been stored in the crop tank; an unloader apparatus that discharges crop that has been stored in the crop tank; a device control part that executes precise measurement oriented device setting processing; a measurement control part including a precise measurement execution part that performs, precise measurement which involves the precise measurement oriented device setting processing, and a simplified measurement execution part that executes, simplified measurement; an operational instruction processing part that outputs a precise measurement instruction and a simplified measurement instruction in response to an operation performed by a manual operation device; and a measurement result recording part that rewrites a simplified measurement result recorded based on a preceding simplified measurement instruction, with a precise measurement result that is based on a succeeding precise measurement instruction.
