TILLAGE ROLL Russian patent published in 2003 - IPC

FIELD: agricultural engineering. SUBSTANCE: tillage roll has rims-disks fixed on shaft. Outer and middle rims-disks are mounted perpendicular to shaft. Toothed planks with equal slot and ridge pitches are secured on rims-disks. Rims-disks positioned between outer and middle rims-disks are positioned in symmetry with respect to plane of symmetry of roll, said plane extending perpendicular to roll shaft, at an angle to shaft of at least 70 deg. Rims- disks are provided with slots for receiving toothed planks. Adjacent planks are arranged in axially offset relation with respect to one another for value equal to slot or ridge pitch. Diameter of rims-disks is equal to diameter of or circle circumscribed about ridges of toothed planks. Toothed planks may be secured on rims-disks at an angle below 10 deg with respect to roll shaft or in parallel with roll shaft. Tillage roll of such construction may be used for crushing soil crumbles, leveling and compacting of soil surface layer. EFFECT: wider operational capabilities, improved quality of soil tillage and reduced labor intensity for manufacture of tillage tool. 3 cl, 2 dwg
