SOIL TILLER Russian patent published in 2016 - IPC A01B33/06 A01B39/16 A01B49/02 

FIELD: machine building.

SUBSTANCE: invention relates to agricultural machine building, particularly to soil tillers. Soil tiller includes conical reduction gears (6.7) installed on frame (1), which output shafts axes of rotation are inclined forward at angle (α), and on their ends hexagonal sprockets (15) are mounted. Sprockets are equipped with tips (18) with L-shaped blades (20, 21). Left and right rotors blades (20.21) and tips (18) are interchangeable by attachment, but are mirror reflection of each other. Input shafts of reduction gears (6, 7) are oriented opposite to each other and by sprockets (8, 9, 11, 12), of longitudinal shaft (10) and cardan shaft (30) transmit opposite direction of rotation to right and left rotors. At that, blades (20, 21) have contact with soil only in front part of their motion trajectory. For spacing surface shape leveling by means of rotor rotation direction reversing gear boxes (6, 7) are turned at 180°, and tips with blades, are switched over from right rotor to left, and vice versa.

EFFECT: such design solution provides for expansion of tiller functional capabilities, as well as simplification of its design.
