SOIL TILLAGE TOOL Russian patent published in 1998 - IPC

FIELD: agriculture. SUBSTANCE: tillage tool has frame, batteries of spherical disks and flat hoes with levelers, batteries made in the form of shaft with disks and arranged in overlapped relation behind levelers. Disks are inclined toward axis of battery. Angles of inclination to axis of section of disks of at least one battery are different in any plane extending through axis of battery. Angle between planes in which disk sections have maximum inclination angle to axes for adjacent disks does not exceed 0.5 0,5π to eliminate plugging with soil lumps and sticking to disks during tillage of water-logged and lumpy soil. Total number of equally inclined disks in battery is N/n rounded to whole number, where N is number of disks in battery and n is number of sides of polygon in central opening of disk. Such construction provides high-quality crumbling of soil and compaction of mellowed soil layers. EFFECT: increased efficiency, improved quality of soil and enhanced reliability in operation. 3 cl, 6 dwg
