POLYFUNCTIONAL TOOL FOR SOIL TREATMENT Russian patent published in 2017 - IPC A01B49/02 

FIELD: agriculture.

SUBSTANCE: polyfunctional tool includes a welded two-double-bar frame (1) equipped with a hinge system, supporting elements and working elements arranged in the staggered order. The tool comprises racks (4) made in the form of pipes of circular cross-section with the diameter of 90-95 mm . The racks (4) are equipped with lamellar extensions with openings for their attachment and reinstallation by height. Double lamellar brackets (20) are fixed in front to the bars. Flat hoes (7) are made semicircular with sharpening, are installed at an angle of 10-13° and have agitators in the form of metal strips cut partially at the end of the rear hoe part and bent at an angle of 40-50°. The tool also comprises bits (10), removable drainers, mouldboard housings, worm reducers (16) with elongated shafts in hinge supports. The reducers (16) are mounted on fixed platforms, arranged from behind of the bars, behind the double brackets, and equipped with engines powered from a tractor battery, similar to screwdriver engines known in practice, and reverse-rotation systems. The extensions (5) are welded to the rear of the racks (4) along the entire length and serve for additionally fixing the hoes (7), reinstalling them by height and fixing the drainers. The worm reducers (16) with elongated shafts are installed on the platforms (15). The platforms (15) are fixed to cylindrical housings (14), equipped with hinged supports, holders (13) and sliders. The sliders are put on guides, vertically welded, made in the form of a rectangular pipe with openings for locking fingers. The mouldboard housings (19) are made of the concave cylindrical shape, equipped with sharpening and rigidly mounted at the ends of the elongated shafts (18) perpendicularly and strictly in the middle by means of bolted brackets (20) equipped with bushings with the openings for the locking fingers (21).

EFFECT: reducing the power consumption, improving the operational reliability and the tillage quality.
