MULTIFUNCTIONAL COMBINED MACHINE FOR SOIL CULTIVATION BY IMPULSE IMPACT OF A SHOCK WAVE Russian patent published in 2021 - IPC A01B49/02 

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular to technical means for the main moldboard-free tillage. The multifunctional combined machine for soil cultivation by impulse action of a shock wave contains a carrying frame and three sections. The first and third are folding, the second section - the basic one - is made with a boot, support and transport wheels and a compressed air cylinder. The front frame of each section is equipped with rigidly fixed working bodies in the form of a cultivator paw with built-in pneumatic tubes with outlet openings located at the ends of the paw wings from the inside, installed at an acute angle to the horizontal surface and directed against the movement of the unit, with a radius of action of 5 ... 10 cm. Depth ratio surface tillage of cultivator paws to the depth of subsoil treatment by impulse blows of compressed air is 1:2. Disc cutters and harrows with a working depth of 5 ... 7 cm are installed behind the cultivator paws.

EFFECT: use of the proposed device will improve the quality of soil cultivation by cutting and loosening the soil simultaneously with one working body.
