DISK-TYPE TILLAGE TOOL Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: tillage tool has frame 1 and transverse bars mounted on frame 1. Slider bearings are attached to transverse bars. Tines with spindles are located in bearings. Spherical disks are mounted on spindles so that angles α of attack may be changed by moving tie-rod connected to carrier attached to tine upper end. Disks are positioned so that their convex and concave sides are oriented in opposite directions to form first paired row. In subsequent adjacent paired rows disks are arranged in opposed relation to disks of first paired row of disks. Each subsequent disk is offset transverse to previous disk toward ground strip defined between disks and left untilled by first row of disks. Offset value is partial of dividing space between disks by number of rows. Disks are inclined at an angle of β to vertical plane. EFFECT: improved quality and crushing extent of tilled soil layer and reduced power consumption for soil tillage.
