FIELD: agricultural engineering, in particular, technique for mechanized harvesting of cereal crops. ^ SUBSTANCE: vacuum grain combine has platform with drive part and cabin, power unit and grain harvester equipped with transverse cuts connected through channels, pockets and openings to transportation pipe joined to cyclone. Discharge pipe of cyclone is joined to discharge pipe having telescopic portion and discharge cyclone. During operation of combine, air flow is fed into transportation pipe for providing suction of air through transverse cuts of grain harvester. Sucked air withdraws grains from ears and delivers it through transportation pipe into cyclone where grain is settled and accumulated. Accumulated grain is carried away through discharge pipe into discharge cyclone to be further delivered into vehicle. ^ EFFECT: increased efficiency due to elimination of outside mechanical actions upon grain during harvesting procedure. ^ 1 dwg |
