FIELD: agriculture.
SUBSTANCE: method for harvesting grain crops and soybeans includes mowing 1 grain mass and transporting 2 it to a rotary threshing-separating device for thrashing 3, with selecting a grain heap 4 and straw 5. Then the straw is ground 6 and scattered 7 over the field. The grain heap is transported 8 with an air jet of a blade fan through a loading window to a storage hopper. When the grain heap comes in the storage hopper, it is blown 9 with a directed air jet through a sieve installed inside the storage hopper below the loading window. Chaff is blown out 10 of the storage hopper through a chaff wadboard packer by an air jet of a blade fan. Grain passes through the openings in the sieve and settles 11 in the storage hopper.
EFFECT: method improves the efficiency of harvesting grain crops and soybeans due to reducing transportation costs.
