FIELD: agricultural engineering.
SUBSTANCE: invention relates to agricultural engineering and can be used for harvesting grain crops by stripping growing plants. A combine harvester, including a stripping adapter, an inclined chamber and a beater threshing drum, a device for preliminary separation of free grain from a stripped heap, placed between the threshing drum and the inclined chamber and containing a separating grate and a scraper conveyor mounted above it. In this case, the leading sprockets 6 of the scraper conveyor 5 are mounted on the shaft of the threshing drum 3, the circumferential pitch of the location of the rasps 7 of which corresponds to the pitch of the scrapers 8 of the scraper conveyor 5. The diameter of the sprockets 9 of the driven shaft of the scraper conveyor 5 is smaller than the diameter of its leading sprockets 6.
EFFECT: combine harvester provides increased manufacturability.
