Abstract
A finger-hoe tool for a soil-tilling device, which has at least one finger, and a method for mechanical control of weeds in row crops make possible an input of loose materials into the row or a discharge of loose materials from the row, because the at least one finger has at least one device for collection and/or removal of the loose materials (e.g. earth, sand, stones), whereby not only the weakly rooted weeds but also more strongly rooted weeds can be controlled.
Claims7
A finger-hoe tool for a soil-tilling device, the finger-hoe tool comprising:
- an axis of rotation,
- a star wheel comprising a central base region, a plurality of fingers, an upper side turned away from the soil, and an underside turned toward the soil, the fingers connecting to and extending away from the central base region, the central base region being disposed in a base plane, the fingers extending in the base plane,
- a soil drive element provided with an axis of rotation, and
- at least one means for collection and/or removal of loose materials, the at least one means for collection and/or removal of loose materials being connected to a respective finger of the plurality of fingers, the at least one means for collection and/or removal of loose materials comprising:
- a projection protruding out of the base plane and/or
- a hollow protruding into the base plane,
- wherein the axis of rotation of the finger-hoe tool corresponds to the axis of rotation of the soil drive element,
- wherein the soil drive element is connected interlockingly with the star wheel, and
- wherein the at least one means for collection and/or removal of loose materials is disposed on the upper side of the star wheel and/or the underside of the star wheel.
A method for mechanical control of weeds in a row of crops, the method comprising:
- providing a soil-tilling device comprising:
- at least one finger-hoe tool comprising:
- an axis of rotation,
- a star wheel comprising a central base region, a plurality of fingers, an upper side turned away from the soil, and an underside turned toward the soil, the fingers connecting to and extending away from the central base region, the central base region being disposed in a base plane, the fingers extending in the base plane,
- a soil drive element comprising an axis of rotation, and
- at least one means for collection and/or removal of loose materials, the at least one means for collection and/or removal of loose materials being connected to a respective finger of the plurality of fingers, the at least one means for collection and/or removal of loose materials comprising:
- a projection protruding out of the base plane and/or
- a hollow protruding into the base plane,
- wherein the axis of rotation of the finger-hoe tool corresponds to the axis of rotation of the soil drive element,
- wherein the soil drive element is connected interlockingly with the star wheel,
- wherein the at least one means for collection and/or removal of loose materials is disposed on the upper side of the star wheel and/or the underside of the star wheel, and
- driving the soil drive element such that the star wheel and the fingers are driven.
