    The invention relates to an adjustable chopping device for removing weeds located on a floor between rows of useful plants which are arranged at a distance from one another on the floor, the chopping device having a support frame which is set up for attachment to an agricultural vehicle and on which at least one chopping unit is arranged with a processing width that can be adjusted to the row spacing.
    Chopping devices usually remove the weeds or weeds from the rows in row crops in the field, for example pumpkin, corn or beets, but also trees or shrubs, the individual rows being arranged at a certain distance - also called row spacing.
    Without chopping or removing the weeds, the actual crop would be overgrown by the weeds or weeds or would be very severely impaired in its development, as a result of which the harvest yield would decrease considerably.
    The processing width on the chopping devices or the chopping units themselves is permanently set and can currently only be adjusted with great difficulty and with considerable loss of time.
    Therefore, such an adjustment of the working width on the chopping device is often not carried out by users and different row crops or crops on the ground are processed with a constantly set working width on the chopping device. However, this does not take into account the growth of the plants during a season.
    It is an object of the invention to provide an improved chopping device which enables the machining width of a chopping unit to be set more easily.
    This object is achieved in that the chopping device has at least one chopping unit, which comprises the following:
    2/24
    PI7121
    - At least one rectilinear base web and at least two cross struts, which cross struts are each rotatably mounted about an axis of rotation on the at least one base web, the axes of rotation being arranged parallel and in one plane along the longitudinal extent of the base web, and in each case at least two cross struts parallel to one another are arranged
    at least one connecting web running parallel to the at least one base web, which mechanically connects the at least two cross struts to one another, so that rotational movements of the cross struts are coupled to one another,
    - At least two coulters for removing the weeds located on the ground, which coulters are arranged at a normal distance from the base web on the at least two cross struts in a definable orientation to the base web, the alignment of the shares remaining unchanged when the corresponding cross struts are turned, and
    - At least one actuating device with a drive unit for rotating at least one cross strut, a rotation of the cross struts changing the normal distance of the shares to the base web, and wherein the normal distance of the respective shares is continuously adjustable between a largest and a smallest normal distance.
    The possibility of adjusting the working width enables the user to chop much closer to the rows of crops and thus reduces weed growth directly next to the plants. Furthermore, the processing width can be individually adjusted or set for each plant crop, it being possible to adjust the processing width several times while the chopping device is in operation.
    A common row spacing can be between 12.5 cm to 75 cm or more.
    Furthermore, there is the possibility to adjust the working width accordingly from field to field between different growth stages or growth phases or between different crops during cultivation of the soil.

    PI7121
    It should be noted that the coulters are mounted on the cross struts in such a way that when the cross struts are rotated or the processing width of the at least one chopping unit is adjusted by means of the adjusting device, the alignment of the cutting coulters with respect to the longitudinal direction of the base web is maintained or not changed .
    It should also be noted that the position of the cutting shares and the associated kinematics are selected such that regardless of the set processing width of the chopping unit, the cutting shares do not lie in any common plane, perpendicularly and parallel to the longitudinal direction of the base web, in order to ensure the best possible earth flow and a jam to prevent harvesting and chopping residues.

    In the examples from FIGS. 1, 2, 2a, 2b, 3a, 3b, the actuating device 400 engages at one end of a cross strut 250 and the base web 200 in order to twist the cross struts 250 by means of the linearly displaceable adjusting arm.

    FIG. 5 shows the exemplary chopping device 10 from FIG. 1 / wherein the row spacing 20 between the rows of crops shown is smaller and the processing width of the chopping units 100 is accordingly adapted by the respective adjusting device 400.
    However, it is also possible that the actuating devices 400 of the chopping units 100 can be controlled independently of one another, so that the chopping units 100 can have different processing widths.
