摘要：
The claimed utility model relates to agricultural machinery and can be used in the design of pin threshing devices of combine harvesters for harvesting rice and crops with high humidity.The objective of the claimed utility model is to increase the productivity of the combine harvester, to prevent the passage of large straw particles through the cells in the concave, reduce grain losses, reduce the load on the pin drum and concave, as well as increase the main working time by eliminating the installation and dismantling of the rear section of the concave and finger combs.To achieve the indicated technical result, a concave extension, a bar-stripe concave and a finger comb are introduced into the inventive utility model comprising a frame, a receiving beater, a pin drum and a breaker beater, while the concave extension consists of a welded frame formed by the side walls, a transverse cross, transverse angles and longitudinal plates, the lining on which the fingers are mounted, the receiving visor and the lower flap, mounted on the transverse side of the concave with bolted unity. The overlay is a bent profile made of sheet metal and consisting of four shelves of different widths, bent at a certain obtuse angle, the overlay describing the shape of the curved arc of the side wall of the concave extension frame and mounted on the shelves of the transverse corners. On three, of four shelves, square holes are made, located in each row and between the rows at the same distance from each other, while the holes of the second row are offset relative to the first and third rows by an amount equal to half the distance between the two holes.Заявляемая полезная модель относится к сельскохозяйственному машиностроению и может быть использована в конструкции штифтовых молотильных устройств зерноуборочных комбайнов для уборки риса и культур с повышенной влажностью.Задачей заявляемой полезной модели являются увеличение производительности зерноуборочного комбайна, исключение прохождения
