FIELD: agriculture.SUBSTANCE: invention relates to agricultural machinery industry. The catching device comprises two parallel placed longitudinal conveyors (1 and 2). On the oppositely located sidewalls of the conveyors on the rotary levers (15) two rows of discs (6, 7 and 12, 13) are freely mounted with the ability of free rotation on the axes (16). The surfaces of the discs have a slope towards the outer sidewall of the corresponding conveyor (1 and 2). The discs mounted on each of the conveyors are arranged with overlapping and alternation in height in two tiers, and their rotary levers (15) are spring-loaded. Each rotary lever (15) is made cranked, i.e. consists of three units. The link (20) on which the disc rotation axis is fixed, in the initial position, when the discs of the opposed rows are at a minimum distance from each other, is arranged parallel to the longitudinal-vertical plane of the machine and above the conveyor surface (1 or 2), and the link (22) which is mounted directly on the side of the conveyor (1 or 2) is oriented in a horizontal plane at an acute angle to the longitudinal-vertical plane of the machine and is located below the conveyor surface (1 or 2). The outermost links (20 and 22) of the rotary lever (15) are interconnected by the vertical link (21), and the axes (16) of rotation of the discs of different tiers have different lengths.EFFECT: reduction of the likelihood of the catching device failure is ensured.2 cl, 2 dwg |
