Patent ID: 7685749

Claim:
Soil stripping device comprising: a base body connectable to a carrier implement, a work unit, soil working tools arranged on the work unit a bearing device supporting the work unit on the base body in a rotatable manner, a rotary device for rotating the work unit with respect to the base body about an axis of rotation, wherein the rotary device includes: at least one linear drive for generating linear movement, wherein the linear drive has a double-acting setting cylinder having a cylinder housing having first and second sides and first and second piston rods protruding respectively from the first and second sides of the cylinder housing, wherein the double-acting setting cylinder is arranged on the work unit, and transmission means for translating linear movement generated by the linear drive into a rotating movement, wherein the transmission means includes a setting wheel, and first and second flexible elements each having first and second ends, the first end of each flexible element being linked to the setting wheel and wound around the setting wheel in opposite directions to effect rotation of the setting wheel in opposite directions when tensile forces are applied to the second flexible elements, the second ends of the first and second flexible elements being respectively attached to an end of the first and second piston rods.
