UNIVERSAL TILLAGE TOOL Russian patent published in 2014 - IPC A01C5/04 A01B13/04 A01B33/14 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to devices for forming holes for planting forest crops. The universal tillage tool comprises a frame (1) with a gear (2). On the sides of the output vertical shaft (3) of the gear (2) the working elements for tillage are secured. The continuation of the shaft (3) is the auger (7). The working elements are made in the form of three concave disks (4). Mounting of the disks (4) on the vertical shaft is made by means of the holder (6) and the leash (5). The leash (5) and the holder (6) provide turning of the disks in the working position of "gathering" (formation of microelevations) or "cast" (formation of recess). The concave disks (4) are located in the leashes (5) on their axes (8) with the ability of free rotation. The angles between the adjacent concave disks (4) are equal to 120°. To move the concave disks (4) in the radial direction and their fixation in the specified position in the leashes (5) the longitudinal slots are made. The holder (6) is made with the ability of movement and fixation in a specific position on the vertical shaft (3).

EFFECT: constructive solution enables to create microelevations of the specified sizes under conditions of temporarily over-moistured soil, as well as sites with simultaneous making holes.
