COMBINED UNIT FOR TILLAGE AND SOWING (VERSIONS) Russian patent published in 2015 - IPC A01B49/06 A01C7/20 

FIELD: agriculture.

SUBSTANCE: combined unit for tillage and sowing comprises a wheel traction means (1), a hopper (12) for seeds, compacting rollers (16), a frame (4) of the tool. On the frame (4) of the tool the hollow racks with disc coulters (7) are placed. The coulters (7) are located in succession on two bars (5) and inclined in the longitudinal and transverse planes. The bars (5) are fixed with the front ends of the frame (4) on vertical axes (8) with the ability of rotation in a horizontal plane. The coulters (7) are fixed to the hollow racks with the possibility of partial overlapping with each previous opener of them of the next one (7). The tool can be connected with the traction means (1) by the hitch linkage (2) and is fastened to the rear half-axes (13) of the traction means or by hydraulic hitch linkage and at that to comprise the compacting rollers (16) placed at an angle to each other. The frame (4) of the tool can be divided by the longitudinal axis (18) to the central section (19) and the outermost sections (20), and the rear ends of adjacent bars (5) of the different sections are pivotally connected to each other and the sliders (22) with the longitudinal axes (18).

EFFECT: increased efficiency of soil tillage and reduction of energy consumption, with ensured optimisation of the traction means load.
