Soil-cultivation device

A soil cultivation device for mechanical weed control in rows of cultivated plants, the soil cultivation device comprising:

• a frame attachable to a tractor for movement along a traveling direction (F);
• and
• at least one processing unit attached to the frame,
• wherein the at least one processing unit has at least one tool carrier unit with at least one soil cultivation tool arranged on the at least one tool carrier unit,
• wherein at least one deflecting means is provided for deflecting the at least one tool carrier unit, wherein a deflection of at least a partial region of the at least one tool carrier unit in at least a direction (A, −A) transverse to the traveling direction (F) can be realized with the aid of the at least one deflecting means,
• wherein the soil cultivation device has at least one drive means for driving the at least one tool carrier unit,
• wherein the at least one soil cultivation tool can be moved on an endlessly circulating path due to a movement of the at least one tool carrier unit, wherein the at least one drive means for driving the at least one tool carrier unit is configured in such a way that the at least one tool carrier unit can be moved with a speed, which is adapted to the speed of the tractor in the traveling direction (F), in such a way that the at least one soil cultivation tool engages into regions between two successive cultivated plants of a row of cultivated plants, wherein the at least one soil cultivation tool can be moved in a tool direction (W) in a section of the endlessly circulating path near the ground, wherein the tool direction (W) is at an angle α relative to the traveling direction (F), and wherein α satisfies a condition 90°<α<180°,
• wherein the at least one tool carrier unit forms a circular disk, wherein the at least one drive means for driving the at least one tool carrier unit is a drive means for driving the circular disk, wherein the circular disk is set in rotation by the drive means, wherein the at least one deflecting means for deflecting the at least one tool carrier unit is a deflecting means for deflecting the circular disk, wherein the circular disk can be deflected in a direction (A, −A) transverse to the traveling direction (F) by the deflecting means,
• wherein the deflection of the circular disk can be realized in such a way that the circular disk is at an angle β relative to the traveling direction (F), wherein β satisfies a condition 90°<β<180°, and wherein α=β, and
• wherein a circular guide disk is provided, wherein the at least one soil cultivation tool is guided by a recess provided in the circular guide disk.
