PROBLEM TO BE SOLVED: To prevent the case in which a large amount of grains is sent to a straw rack, the grain is scattered from the straw rack and discharged from a dust feed port and the case in which a circulation that grain leaked from the straw rack is sent through a second screw to a treatment rotor and the grain sent to the treatment rotor is leaked to the straw rack again is repeated in the machine of combine harvester.
SOLUTION: The grain threshing machine has a constitution that a detection sensor 34 for a grain amount is arranged below the rear end of a crimped wire net 15, the actions of a dust-sending valve 10a and a chaff sieve 18 are controlled on the basis of the detection result detected by the detection sensor 34 for a grain amount, an amount of grains leaked from the chaff sieve 18 is increased, and an amount of grains sent from the chaff sieve 18 to a straw rack 19 is reduced.
