Abstract
A weeding unit for treating an agricultural field includes a carrier, at least one working lever movably connected with the carrier, at least one actuator for moving the at least one working lever, and a control unit. The control unit is configured to distinguish crop from weed and to control the at least one actuator for treating the weed. The at least one working lever includes a weeding knife and at least one harrowing tine. Methods for treating an agricultural field are also disclosed.
Claims19
A weeding unit for treating an agricultural field, comprising:
- a carrier;
- at least one working lever movably connected with the carrier;
- at least one actuator for moving the at least one working lever;
- and
- a control unit configured to:
- distinguish crop from weed;
- and
- control the at least one actuator for treating the weed;
- wherein the at least one working lever comprises:
- a weeding knife;
- and
- at least one harrowing tine;
- wherein the at least one harrowing tine is movably connected with the weeding knife for moving the at least one harrowing tine relative to the weeding knife;
- and
- wherein the at least one harrowing tine is pivotably connected with the weeding knife at a pivot axis.
A weeding unit for treating an agricultural field, comprising:
- a carrier;
- at least one working lever movably connected with the carrier;
- at least one actuator for moving the at least one working lever;
- and
- a control unit configured to:
- distinguish crop from weed;
- and
- control the at least one actuator for treating the weed;
- wherein the at least one working lever comprises:
- a weeding knife;
- and
- at least one harrowing tine;
- wherein the at least one harrowing tine is movably connected with the weeding knife for moving the at least one harrowing tine relative to the weeding knife;
- wherein the least one working lever comprises a first actuating element configured to move the at least one harrowing tine into a first deflected position;
- wherein the at least one working lever comprises a second actuating element configured to move the at least one harrowing tine into a second deflected position;
- wherein the first actuating element and the second actuating element are configured to move the at least one harrowing tine contrary for urging the at least one harrowing tine into a neutral position;
- wherein the least one working lever comprises at least one adjuster for adjusting the actuation force of the actuating element;
- and
- wherein the at least one adjuster comprises an adjustment screw integrated into the weeding knife.
A weeding unit for treating an agricultural field, comprising:
- a carrier;
- at least one working lever movably connected with the carrier;
- at least one actuator for moving the at least one working lever;
- and
- a control unit configured to:
- distinguish crop from weed;
- and
- control the at least one actuator for treating the weed;
- wherein the at least one working lever comprises:
- a weeding knife;
- and
- at least one harrowing tine;
- wherein when the at least one harrowing tine is in a neutral position, a ground engageable end of the at least one harrowing tine is more distant from the carrier than from a blade of the weeding knife.
A method for treating an agricultural field with a weeding unit traversing the agricultural field, the method comprising:
- detecting crop in a crop row of the agricultural field;
- moving at least one weeding knife to an opened position and moving at least one harrowing tine to a neutral position to prevent treatment of the crop by the at least one weeding knife and the at least one harrowing tine;
- moving the at least one weeding knife to a closed position while the at least one harrowing tine remains in a deflected position to treat the crop row with the at least one weeding knife;
- and
- moving the at least one harrowing tine to the neutral position to the closed positing to treat the crop row with the at least one harrowing tine.
