Definitions

  • the generic method generally describes a procedure for the replacement of a working device of a tillage machine to a working device pair with the machine frame of the tillage machine ready for use.
  • the pamphlets DE 10 2014 011 856 A1 and DE 10 2011 018 222 B4 suggest a kinematic reversal of the aforementioned sequence, ie a movement of the working device in the machine frame transverse direction under a provided machine frame.
  • an additional maneuvering device is necessary because the working device taken by itself is usually not equipped to move relative to the ground.
  • the working device can be connected to the machine frame in a pendulum fashion, so that when the working device connected to the machine frame is suspended therefrom leaves, this can move automatically gravity driven in a predetermined relative position relative to the machine frame.
  • the connecting device is suitably dimensioned or / and the connecting device between the machine frame and the working device is appropriately oriented when its coupling sections are coupled to the machine frame and the working device, the working device alone under the effect of its weight can assume a predetermined relative position in which the fixing formations and opposing formation formations are sufficiently aligned in an alignment plane spanned by parallel to the machine frame longitudinal direction and the machine frame transverse direction and can be easily approximated to one another.
  • the alignment plane relative to the tillage machine is not important. The alignment plane only serves to specify a relative position of the working device and machine frame, regardless of the height position of the working device, only in the coordinates "machine frame longitudinal direction" and "machine frame transverse direction".
  • the machine frame is arranged before or during the alignment so that the alignment plane is oriented orthogonal to the direction of gravity action.
  • the number of device coupling formations may be larger or smaller than the number of frame coupling formations, such as when the connection device branches between the frame coupling section and the device coupling section. Since three points define a plane, it is advantageous if three non-collinear coupling sections provided at a distance from one another are provided on at least one object of the machine frame and the working device. In principle, it suffices if only one coupling section is provided on the other object of the machine frame and the working device, in which case an additional adjustment intervention by one or more employees may be necessary in order to obtain a relative rotation which is basically possible with only one coupling formation present at one end of the connecting device between working device and machine frame to prevent or correct an axis of rotation parallel to the axis of gravity direction of rotation.
  • the relative rotation about a rotation axis parallel to the direction of gravity action can be hindered or even prevented.
  • the relative position occupied by the working means relative to the machine frame, when freely suspended therefrom, can be uniquely determined, regardless of where the focus of the work facility is.
  • connection device can absorb three gravitational tilting moments at the coupling points via three device coupling formations which are arranged non-collinearly on the working device, so that such tilting moments do not result in any tilting movement of the working device relative to the machine frame.
  • the working device is movable under the action of its weight parallel to the direction of gravity of gravity and orthogonal to this, this should be understood as a measure of the stiffness of the connecting device.
  • the connecting device does not have to be so limp that it is already deformable in the unconnected state, which is not coupled to the machine frame and the working device. Then, however, when the working device is suspended by the connecting device on the machine frame oscillating, the connecting device is driven by the weight of the working device to allow the described movement.
  • the mobility parallel to the direction of gravity action and orthogonal thereto is to ensure that the work equipment, when freely suspended from the machine frame, assumes a desired relative position in which the work equipment has the least potential energy. If the work equipment is in a position of higher potential energy, the connection device should allow movement of the work equipment in the direction of gravity action until the location of least potential energy is reached. In this movement, the connecting device guides the working device orthogonally to the direction of gravity action - just like a pendulum - so that the working device, when it reaches and rests in the lowest potential energy location, assumes a desired end position in the aforesaid alignment plane the approximation of the fixing and counter-fixing formations can be made to achieve a locking engagement therebetween.
  • the working device is located between the base and the machine frame, but offset with respect to their relative position to the machine frame in the alignment plane with respect to its attachment position, which allows an operational definition of the working device on the machine frame in the machine frame longitudinal direction and / or offset in the machine frame transverse direction, this offset by the use described the connection device and made possible by them swinging suspension of the working device on the machine frame in the manner described.
  • the frame coupling section of the connection device can have one or more coupling shapes, each of which can be coupled to a frame coupling formation, preferably being positively coupled.
  • the device coupling portion of the connection device may include one or more device coupling shapes, each of which is coupleable to a device coupling formation. This coupling is preferred to ensure the transferability of the largest possible forces form fit.
  • the number of frame coupling shapes may be larger or smaller than the number of the device coupling shapes.
  • connection device has as many frame coupling shapes as device coupling shapes, in order to be able to distribute the forces acting on the coupling frames during free hanging of the working device on the machine frame as uniformly and uniformly as possible among the existing coupling shapes. Therefore, also preferably, the number of frame coupling formations is equal to the number of device coupling formations.
  • the device and / or frame coupling formations may be provided at arbitrary locations of the working device and / or the machine frame
  • the at least one device coupling formation is preferably a set formation and / or the at least one frame coupling formation is preferably an opposing set formation.
  • the distance direction in which the fixing formations and associated counter-fixing formations are in alignment with each other runs parallel to the direction of gravity, so that the approaching of fixing formations and counter-fixing formations is prevented by simply lifting the working device the gravity direction of action and / or lowering of the machine frame in the direction of gravity action can take place.
  • the alignment of the working means by swinging suspension on the machine frame and hanging it on the machine frame can be done with great accuracy, since a pendulum suspension of the working device on the machine frame such that after a possibly occurring at the beginning of hanging lethal reciprocating pendulum motion associated fixing and Gegenfestlegeformationen come to rest in the direction of gravity force exactly above each other, is particularly easy to implement.
  • the step of placing the machine frame and the working device relative to one another such that the working device is between the machine frame and the ground may include movement of the machine frame relative to the ground via the working device. This movement preferably takes place parallel to the alignment plane. Additionally or alternatively, the arranging step may include movement of the working device received on a transporting vehicle under the machine frame. Usually, the movement of the machine frame and / or the movement of the working device will have a movement component in the machine frame transverse direction or even run predominantly or completely in the machine frame transverse direction.
  • the step of suspending the working device movably connected to the machine frame may comprise lifting the machine frame relative to the ground and / or lowering a working device carrying carrying device of a transporting vehicle relative to the ground.
  • the lifting of the machine frame can be easily realized if the machine frame of the tillage machine, as is often the case, is supported by a hoist height variable above the ground.
  • the hoist can include one or more lifting columns, with which drives the machine, for example via hydraulic piston-cylinder arrangements are arranged vertically adjustable on the machine frame.
  • the step of supporting the working device may comprise lowering the machine frame relative to the ground, in particular until the working device settles on the ground, and / or lifting a carrying device carrying a carrying device of a transporting vehicle relative to the ground.
  • the hoist it is preferable to lower the machine frame by means of the hoist.
  • connection device allows for relative rotation between work implement and machine frame about the yaw axis of the machine, albeit a slight one.
  • the connecting device extends even in the aligned state of the working device parallel to the direction of gravity action.
  • the connecting device may comprise, at least in sections, a chain or a cable which, in the fully aligned state in which support is carried out, is then preferably in a position stretched parallel to the direction of gravity of action.
  • connection device permanently coupled to the machine frame and / or to the working device.
  • a processing machine with permanently coupled with this connection device without prior setup to align a working device.
  • connection device may also be advantageous to remove the connection device from the soil tillage implement when it is no longer needed. This is the case, for example, when the connection device is coupled on the machine frame side and / or work side with the fixing formations and / or the opposing fixing formations, so that the connecting device could hinder the production of a locking engagement between said formations or already approaching the fixing formations and the opposing fixing formations.
  • the removal of the connecting device is preferably carried out after supporting the working device and before setting the working device on the receiving portion. Then, when a separate fixing means is needed for operational definition of the working device on the receiving portion, such as a fixing bolt, a fixing screw or a screw-nut combination, the connecting device can be replaced by the fixing means.
  • the connecting device comprises exactly one piece, for example when the connecting device branches between the frame coupling section and the device coupling section.
  • the connection device comprises a plurality of sub-connection devices, each of which has a frame coupling section adapted to be coupled to the machine frame and a device coupling section arranged at a distance from the frame coupling section and adapted to be coupled to the working device.

  • each sub-connection device may be mutually connected to one another via a common connection component or may form the connection device unconnected as separate sub-components.
  • each sub-connection device at least partially a Chain and / or have a rope. Due to the greater load carrying capacity of ropes and due to the higher internal friction between the rope strands, as compared to chains, provided by ropes, the use of rope material to form the connection device or the sub-connection devices is preferred.
  • connection device or the part connection devices in general can be provided inclined against each other in the state coupled to the working device and machine frame, so that forces acting in the alignment plane add up to a total force of zero.
  • the present invention also relates to a tillage machine having a machine frame and a working device connected to the machine frame, in which the working device is connected to the machine frame by means of a connecting device which, due to the advantageous effect of the oscillating on the machine frame suspended for the purpose of alignment of work equipment and machine frame a frame coupling portion coupled to the machine frame and a device coupling portion spaced apart from the frame coupling portion and coupled to the working device, the frame coupling portion and the device coupling portion being coupled at least parallel to and perpendicular to the gravity direction of action the weight of the working device are movable relative to each other.
