Hoeing device

An adjustable hoeing device (10) for removing weeds that are present on the ground between rows of agricultural crops, which are set out on the ground in a spaced manner with a row distance (20) from each other, with the hoeing device (10) comprising a supporting frame (50), which is designed to be attached to an agricultural vehicle and on which at least one hoeing unit (100) with a processing width that is settable to the row distance (20) is disposed, with the hoeing unit (100) comprising the following:

• at least one main bar (200) extending in a straight line and at least two transverse bars (250), which transverse bars (250) are respectively mounted on at least one main bar (200) so that they are rotatable about an axis of rotation, with the axes of rotation disposed in parallel along the longitudinal extent of the main bar (200) and in one plane, and with at least two transverse bars (250) being disposed in parallel to each other,
• at least one connecting bar (300) extending parallel to the at least one main bar (200), which connecting bar (300) mechanically connects the at least two transverse bars (250) with each another so that rotational motions of the transverse bars (250) are coupled to each other,
• at least two blades (500) for removing weeds present on the ground, which blades (500) are disposed at the at least two transverse bars (250) at a normal distance from the main bar (200) and in a definable orientation with respect to the main bar (200), with the orientation of the blades (500) remaining unaltered upon rotation of the corresponding transverse bars (250), and
• at least one actuation device (400) with a drive unit for rotating at least one transverse bar, with a rotation of the transverse bars (250) altering the normal distance of the blades (500) from the main bar (200), and with the normal distance of the respective blades (500) being continuously adjustable between a maximum and a minimum normal distance,
• wherein the hoeing device (10) comprises at least two hoeing units (100),
• wherein the actuation devices (400) of the hoeing units (100) are independently controllable by a controller, so that the hoeing units (100) can have different processing widths,
• wherein the actuation devices (400) of the hoeing units (100) comprise at least one position feedback unit comprising a potentiometer, whereby the processing width of the respective hoeing unit (100) can be determined by the position feedback unit, which transmits an appropriate signal to the controller so as to monitor the respectively set processing width of a hoeing unit (100), to readjust it and/or to display it to the user, and
• wherein the position feedback unit comprises a camera, which optically records the processing width to be set and transmits an appropriate signal to the control device.
