摘要：
FIELD: agriculture machine building.SUBSTANCE: unit includes a trailer, where with possibility of transfer by hydraulic cylinders from a horizontal operating position to a vertical position there is a swing frame with wings. Working sections are mounted on wings with overlapping edge. Wings are mounted on frame to transfer them into transport position. All working sections consist of frames, on which in bearing units by means of shafts are mounted tools. Rotary frame is composed of middle rotary beam, at ends of which is pivotally on cross joints are wings. Cross-pieces are equipped with supports that limit turn of wings backward in working position, and downward in transport position, that in transport position is additionally fixed with limiters. On wings by means of spring-loaded hinges in form of cross-pieces are sections of working elements composed of ring-heel discs arranged in staggered order via spacers on 2 transverse shafts. Sections of working elements are mounted on middle rotary beam by means of rotary beam through a system of levers. Rotation of beams with working tools is performed relative to middle rotary beam hydraulic cylinders, located on middle rotary bar and is fixed on trailer in transport position transport retaining pins. Extreme ends of wings are connected with trailer front tie-rods, which consist of 2 parts: front short and long rear. Front short parts of tie-rods have catchers and latch with springs, connected through compensation spring ropes with rotary beam. Rear long parts of tie-rods are connected by one set of ends immovably with U-shaped links installed movably on trailer, and other ends are movably attached to ends of wings through brackets, on which transport wheels are mounted.EFFECT: such design will allow to reduce weight and load on rear wheel of tractor, as well as higher manoeuvrability.2 cl, 7 dwgИзобретение относится к сельскохозяйственному машиностроению.
