FIELD: agriculture.

SUBSTANCE: invention relates to the agricultural machine industry and may be used in devices for harvesting crops. The combine comprises a power supply unit, a threshing machine with a flail drum and a meshed concave, a concave beater of lattice structure and a key straw rack with a cascade of stepped sections. Over the straw rack a transporting system is set with moving fingers. At the beginning of the concave a singular plate is placed. In a drum and concave beater the reflecting shields are mounted in the form of a convex arch along the width of the threshing machine. The reflecting shield installed between the supply device and the threshing drum directs air flow into the internal cavity of the mesh drum at the entrance of the threshing channel that provides a secure grip of the grain mass. The reflecting shield located between the threshing drum and concave beater is installed over the concave beater and directs air flow into the internal cavity of the concave beater at the output of the threshing channel, which contributes to a more intensive drainage of flow of straw from the threshing machine and increase the capacity of the combine harvester.
