COMBINED SOIL TILLAGE IMPLEMENT Russian patent published in 2013 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: implement comprises a trailer device in the form of a hitch frame for connection with a traction facility. The hitch frame is connected with the frame of bars. The frame is made of three hingedly joined sections with the possibility of installing extreme sections into the transport position. The frame is equipped with support and transport wheels (track wheel) with a hydraulic cylinder of track wheel. On the brackets of the frame there are cutting and tilling working elements in the form of legs with stands and levelling discs. Behind the frame there are working elements of rotary type in the form of roller modules, as well as a compensator of vertical oscillations of the hitch frame. The hydraulic cylinder of the track wheel by one end is hingedly connected to the frame, and by the other end it is connected to the axis of the crank mechanism of track wheel. The hydraulic cylinder of track wheel is located symmetrically to the transport wheels. The compensator of vertical oscillations of the hitch frame is made in the form of a traction rod. The traction rod of the frame hingedly fixed by one end to the brackets being rigidly fixed one opposite the other at both sides of the central longitudinal bar of the frame, and by the second end - to the hitch frame. The second end of the traction rod is equipped with a slot extended along the axis for provision of the hitch frame movement in the vertical plane.

EFFECT: design will make it possible to increase reliability of the unit due to simplification of its structure, to increase convenience of its operation and maintenance, to reduce labour intensiveness of manufacturing with simultaneous improvement of soil treatment quality.
