COMBINATION TOOL FOR PRIMARY TILLAGE Russian patent published in 2015 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural engineering, in particular to the combination tillage tools with replaceable working bodies. The combined tillage tool consists of a frame (1) of hinged colter-mouldboard plough, a support wheel (2) with the mechanism (3) of tillage depth control, replaceable working bodies: blade cultivator hoes (4) or the plough housings. The operating width of the blade cultivator hoe (4) is equal to twice the operating width of the plough housing. The tool has a disc section (6). The disc section (6) has an operating width equal to the overall width of the plough housings. When the tool is equipped with the blade cultivator hoes (4) the additional disc section (7) is mounted behind them, as well as the extender (11) of the frame with the additional odd-numbered bracket for mounting the last blade cultivator hoe (4). The disc sections are mounted on the offset beams (8) and rigidly fixed relative to the frame (1). The disc sections (6 and 7) have the tillage depth control mechanism (9) and the mechanism (10) of changing the angle of attack.

EFFECT: design implementation of tool provides high quality of primary soil tillage and enables to improve the energy efficiency of the basic treatment due to the more efficient use of power of traction vehicle.
