The invention is related to agricultural machine-building, in particular, to harvesting machinery, and can be used in designs of reapers. The technical result - higher frame rigidity, lower deforming loads on elements of the drum for feeding cut mass to the inclined chamber, and higher reliability of the device - is achieved by provision of a reaper for a combined harvester-thresher or for a harvesting machine comprising a frame (1) with supports (1, 3), conveyor belts arranged on the frame and adapted to receive cut mass from a cutting apparatus (6) and to convey it from the cutting apparatus (6) to an aperture (5) formed between the conveyor belt, and a rotatable drum (11) for feeding cut mass from the aperture (5) to an inclined chamber arranged behind said aperture (5), wherein, in accordance with the invention, the frame (2) is provided with stiffening ribs (8, 9) disposed between the supports (1, 3), some of the stiffening ribs (8) are mounted between the aperture (5) and the cutting apparatus (6) so that a trapezoid in plan is formed, the stiffening ribs (8) serving as its lateral sides, and other stiffening ribs (9) are mounted in parallel to the first stiffening ribs (8) near adjacent supports (1), and plates (12) with teeth on their free ends are fastened to the drum (11). The frame (2) further includes stiffening ribs (13) arranged in the vertical plane and mounted in the inclines manner. At least three plates (12) arranged radially are fastened to the drum (11).Изобретение относится к сельскохозяйственному машиностроению, а именно к уборочной технике, и может быть использовано в конструкциях жаток. Технический результат - повышение жесткости рамы, снижение деформирующих нагрузок на элементы барабана для подачи срезанной массы в наклонную камеру и повышение надежности устройства - достигается тем, что у жатки комбайна или уборочной машины, содержащей раму (2) с опорами (1, 3), расположенные на раме ленты конвейера для приема срезанной массы от режущего ап
