Abstract
The invention relates to a tool-changing system (10) for an agricultural soil-working machine, with a soil-working tool (20), a tool carrier (40) for carrying the soil-working tool (20), a tension lever (60) which can be brought into an operational tension state by elastic deformation, in which the tension lever (60) extends at least in sections to the rear of the tool carrier and in which the tension lever (60) tenses the soil-working tool (20) to the tool carrier (40) in an operationally reliable manner, and a locking member (80) which is movable relative to the tool carrier (40) and is designed to lock the tension lever (60) in the operational tension state in a locking position.

Tool-changing system (10) for an agricultural soil-working machine, with
- a soil-working tool (20);
- a tool carrier (40) for carrying the soil-working tool (20);
- a tension lever (60) which can be brought into an operational tension state by elastic deformation, in which the tension lever (60) extends at least in sections to the rear of the tool carrier and in which the tension lever (60) tenses the soil-working tool (20) to the tool carrier (40) in an operationally reliable manner;
- and
- a locking member (80), which is movable relative to the tool carrier (40) and is designed to lock the tension lever (60) in the operational tension state in a locking position;
- wherein the tool carrier (40) comprises a locking member intake (50) for receiving the locking member (80) and the locking member intake (50) has a securing stop (56) for receiving a restoring force transmitted to the locking member (80) by the tension lever (60) which is in the operational tension state, characterized in that the securing stop (56) is arranged rear to the tension lever (60) in the operational tension state of the tension lever (60).
Tool-changing system (10) according to one of the preceding claims, characterized in that the tool carrier (40) comprises a stalk-shaped carrier body (46) with a rear end surface (58) or end edge extending upright at least in sections, wherein the securing stop (56) is formed by a stop surface or stop edge extending parallel and/or offset to the rear relative to the end surface (58) or end edge.
Tool-changing system (10) according to one of the preceding claims, characterized in that the locking member (80) has a lateral material recess (86) for receiving a material section carrying the securing stop (56) during the insertion of the locking member (80) into the locking member intake (50).
Tool-changing system (10) according to one of the preceding claims, characterized in that the locking member (80) has a front contact contouring (82), the shape of which is adapted to the contour of the tension lever (60).
Tool-changing system (10) according to one of the preceding claims, characterized in that the tension lever (60) is designed as a spring clip, in particular as a bent wire part.
Tool-changing system (10) according to one of the preceding claims, characterized in that the tension lever (60) is in an upper area (66) circumferential around a free space (68), through which the locking member intake (50) extends in the operational tension state of the tension lever (60).
Tool-changing system (10) according to one of the preceding claims, characterized in that the tension lever (60) has a carrier contact area (64) which, in the operational tension state of the tension lever (60), is pressed against a lever guide area (48) of the tool carrier (40), the tension lever (60) in the carrier contact area (64) being secured laterally against lateral movements by securing flanks (59a, 59b) of the tool carrier (40).
Tool-changing system (10) according to one of the preceding claims, characterized in that the tension lever (60) has a locking section (62) which can be inserted into a lever receiving recess (22b) of the soil-working tool (20).
Agricultural soil-working machine, with
- a tool-changing system (10),
- characterized in that the tool-changing system (10) is designed according to one of the preceding claims.
Method for fastening a soil-working tool (20) to a tool carrier (40) by means of a tension lever (60) and a locking member (80), comprising the steps of:
- arranging the soil-working tool (20) on a tool intake area of the tool carrier (40);
- inserting the tension lever (60) into a receiving recess (22b) of the soil-working tool (20), so that the tension lever (60) extends at least in sections to the rear of the tool carrier (40);
- bringing the tension lever (60) into an operational tension state by pressing the tension lever (60) in the direction of the tool carrier (40), the tension lever (60) undergoing elastic deformation when it is brought into the operational tension state and the tension lever (60) tenses the soil-working tool (20) to the tool carrier (40) in the operational tension state in an operationally reliable manner;
- and
- bringing the locking member (80) into a locking position by moving the locking member (80) relative to the tool carrier (40), wherein the tension lever (60) is locked in the operational tension state by the locking member (80) being in the locking position;
- wherein the locking member (80) is inserted into a locking member intake (50) when it is moved into the locking position, and the locking member intake (50) has a securing stop (56) for receiving a restoring force transmitted to the locking member (80) by the tension lever (60) which is in the operational tension state,
- characterized in that the locking member (80) is subjected to pressure in the locking position by the tension lever (60) which is in the operational tension state.
