AUTOMATED TILLAGE MACHINE WITH HIGH-TURBULENT AIR JET Russian patent published in 2021 - IPC A01B79/00 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machine building, in particular, to technical equipment for basic soil-free tillage. Automated tillage machine comprises bearing frame and three sections. First section 1 and third section 2 are made folding. Second section 3 is basic and is equipped with scraper 4, support 5 and transport 6 wheels, compressed air cylinder 7, needle rolling packs 14 and disk mills 13. Needle rolling pack 14 are made with needle length of up to 10 cm, and disc cutters 13 are made with processing depth for root crops - 15-20 cm and for grain - 8-12 cm. Front frame of each section is made in the form of hollow shaft 8 and is equipped with rigidly fixed on them by working elements made in the form of two arc-shaped knives 11 with sharp angle sharpening of cutting edge. Arched knives 11 are installed one after another with interval of 15-20 cm, front knife is installed on treatment depth of 10-12 cm, rear - 10-12 cm lower. At height of 5 cm from the nose in the cavity of knives 11 there are three exhaust valves 12 of compressed air built in; at that, the central, front, valve is directed at right angle to the vertical axis of the knife and two side ones - at an acute angle. Compressed air pulse action radius is 5 cm, arc-shaped blades 11 are fixed on the frame with possibility of dismantling and displacement in vertical and horizontal planes.

EFFECT: automated tillage machine provides reduction of traction resistance of the unit and improvement of quality of soil treatment.
