MULTIFUNCTIONAL TILLAGE UNIT FOR RESTORATION OF DEGRADED LANDS Russian patent published in 2019 - IPC A01B35/16 A01B79/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to technical means for basic soil-free tillage. Multifunctional tillage aggregate for restoration of degraded lands consists of bearing frame and working elements installed on it with air-pulse drive, three sections 1, 2, 3, rigidly fixed on frame with possibility of dismantling, the first and the third of which are folding, the second section is basic and is made with hitch tongue 4, support 5 and transport 6 wheels and compressed air cylinder 7. Each section is made in the form of two frames. Front frame of each section is made in the form of hollow shaft connected to compressed air cylinder 7, with rigidly fixed on it working elements in form of rim, hollow hub and spokes with detachable cone nozzles in form of housing and sleeve-piston with radial holes on them and pointed tip. Spokes with taper nozzles are made in form of logarithmic spiral. Angle between tapered nozzle and spoke makes 120 °. Heads are installed with possibility of changing their number. Working elements are arranged to displace along the frame when the type of tillage changes. On rear frame of each section there are attached tillage cutters 18 and ring-toothed rollers 19 installed with possibility of their replacement.

EFFECT: such design will make it possible to reduce traction resistance of the unit and to increase productivity due to growth of speed of the unit.
