SPHERICAL DISK OF TILLAGE TOOL

摘要

FIELD: agriculture. ^ SUBSTANCE: spherical disk of tollage tool has cutting blade, slots and holes in central part for installation and fixation of bearing body on axis. Slots are arranged in the form of curvilinear quadrangle with radial sides. Radial sides are arranged along curve of, for instance parabolic shape. Curvilinear radial sides are oriented with their convex side towards direction of disk rotation. ^ EFFECT: such version of design provides for lower traction resistance, improves soil grinding and crushing of stubble remains. ^ 1 dwg
