DEVICE FOR SUBSOIL CULTIVATION, AERATION, IRRIGATION, FERTILIZATION OF ROOT-INHABITED SOIL LAYERS AND METHOD FOR SUBSOIL CULTIVATION, AERATION, IRRIGATION, FERTILIZATION OF ROOT-INHABITED SOIL LAYERS USING DEVICE Russian patent published in 2023 - IPC A01B79/02 A01B49/06 A01C21/00 A01C23/02 A01C23/04 A01B45/02 

FIELD: agriculture.

SUBSTANCE: device for subsoil cultivation, aeration, irrigation, and fertilization of root-inhabited soil layers contains a frame (1) on which a compressor (2) with a compressed air receiver (3) is installed, connected through electric pneumatic valves (26) to each pneumatic hydraulic drill (14). To the frame (1) mounted on the tractor with linkage elements, receiver (3), pump (4) and closed tanks (5) the frame elements (6) of the passive propulsion system (7), made in the form of a closed continuous elastic belt (8), inside which the support wheels (9) with belt tensioner (8) are installed on the frame elements (6) pivotally connected to the linkage elements. The inner surface of the tape (8) is made in the form of elastic sealed containers-distributors (10), between which there are pockets (12). All sealed containers-distributors (10) of compressed air and all containers-distributors of hydrogel solutions, microbial biological products and/or fertilizers are respectively interconnected. Each pocket (12) is equipped with an electro-pneumatic valve (22) for compressed air and an additional electro-pneumatic valve (26) for solution. In the center of the mover (7) on the frame elements (6) with the possibility of synchronous rotation with the belt (8) there is a pressure regulator-stabilizer (16) that connects the receiver (3) with the compressed air distribution container (10) with hoses (17) and closed tanks (5) with distribution containers for hydrogel solutions, microbial biological products and/or fertilizers. Each pneumatic hydraulic drill (14) is connected by corresponding hoses (21 and 23) and electric pneumatic valves (22 and 24) with a compressed air distribution container (10) and a solution distribution container. Each pneumatic cylinder (15) is connected by a hose (25) and an electric pneumatic valve (26) to a compressed air distribution tank (10), equipped with a roller (28) installed in its upper part, interacting with a load limiter (29) limiting load on the belt (8), rigidly fixed to the bottom of the frame element (6). The method of subsoil cultivation, aeration, irrigation, fertilization of root layers of the soil involves loosening the soil with pulses of compressed air by vertically immersing pneumatic hydraulic drills (14) into the soil and by means of a passive propulsion device (7), made in the form of a closed continuous elastic band (8) with pneumatic hydraulic drills (14), through which, after pulses of compressed air and aeration are supplied to the soil, solutions of hydrogel, microbial biological products and/or fertilizers are supplied under pressure into the formed soil pores, cavities and microvoids; the pressure of compressed air and solutions is stabilized; irrigation and fertilization are provided directly to the root system of plants. The tape (8) covers the soil surface, preventing damage to the root system of plants, loss of compressed air and solutions. As the belt (8) moves, the pneumatic hydraulic drills (14) are removed from the soil.

EFFECT: increase in the productivity of root-inhabited soil layers with maximum preservation of its biological and environmental parameters, high quality, mobility and energy efficiency of the technological process.
