FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. The inclined chamber of the combine harvester contains a receiving beater (2), straw combs (3), a separating grate (4) and a device for removing the separated grain heap (5). The separating grid (4) is made in the form of strips with fixed tubes. The tubes are made with holes in one or more rows, directed upwards at an angle αpot. ≤90° in the direction of movement of the combed heap for the exit of compressed air supplied to them under high pressure, at a speed higher than the soaring speed of the non-grain part of the heap, but lower than the speed grain winding.
EFFECT: reduced injury and grain crushing.
