Method for harvesting grain crops, and apparatus, provided therefor, for a harvester

The invention relates to a threshing method for harvesting grain crops, wherein the latter are separated from a crop (3) to be picked up in particular in the form of cereal, said crop is fed to a threshing phase (4) after a pick-up process (arrow B) that has taken place counter to a working direction of travel (AF), and during said threshing phase (4), the crop (3) in the form of the respective grain crops and the constituents in the form of straw (SR) and chaff (SP') are processed (arrow C, arrow D), such that substantial dischargeable constituents (arrow D) are separated from the grain crops, these are fed as a mixture with chaff or similar fine parts as a grain/chaff stream (C) to final cleaning (5), and then the grains, free of these residual constituents, in the form of grains crops are collected, wherein, during at least one feeding phase (Z) upstream of the final cleaning (5), a transporting movement (T) having a component in a vertical direction (R) and a component in a working direction of travel (AF') is imparted on the at least one grain/chaff stream (C).
