DISK BATTERY OF TILLAGE TOOL Russian patent published in 2006 - IPC A01B23/06 A01B21/08 

FIELD: agricultural engineering.

SUBSTANCE: disk battery has shaft with spherical disks put thereon, spacer bushings and self-setting bearing supports connected to frame through poles. Spacer bushings are made in the form of cylindrical compression springs arranged in successive alternation, beginning from any end, with left-hand and right-hand direction of coils. Poles are made in the form of arced rigid forks with straight portion at upper point which is attached to frame, and two axially aligned symmetrical cams. Width of cams is greater than projection of disk deflection. Each of disks is equipped with two-sided thrust roller bearing rigidly fixed in central opening of disk. Outer connection sizes of thrust roller bearing, outer diameters of cylindrical compression springs and outer diameters of arced fork cams are equal to one another. Additional thrust roller bearings are disposed between ends of arced fork cams and compression springs. Disks are put onto shaft with radial gaps equal to at least half the diameter of shaft.

EFFECT: improved quality of soil tillage by individual response of each disk to force occurring during soil tillage.
