Definitions

  • the present invention relates to a header with a mechanical bottom sensing device having a connected to the header and a transversely to the direction of the harvesting header aligned pivot axis movable TastAvem whose deflections are evaluated in the vertical direction for attitude control of the header.
  • the document DE 102 27 484 A1 discloses a device and a method for attitude control of a header attachment, in the concrete example of a cutting unit for a combine harvester.
  • feelers are mechanical probes used to scan the height of the cutterbar to the ground, on both sides of the cutterbar.
  • the Tastbügel are movable at its front end about an aligned transversely to the direction of the header attachment pivot axis. The pivoting movements of the Tastbügels around the pivot axis are converted via a rotary potentiometer in electrical control signals that can be evaluated to the position control of the cutting unit.
  • the contact skids are usually designed as solid metal castings in order to be able to set sufficient resistance against the longitudinal and transverse forces acting on them.
  • the acting forces result from the ground contact of the Tastkufe.
  • the scooter drags functionally necessary over the ground and is exposed to considerable frictional forces. It collides with obstacles sen or is trapped in columns.
  • the Tastkufen must also be able to absorb lateral forces during operation, for example when cornering and reversing, and be dimensioned accordingly stable. Also, the suspension parts must be made very stable to carry the skids and absorb the forces acting.
  • feeler skids can move in the vertical direction and avoid obstacles, nevertheless, there are always damage to the skids, through which the harvester fails altogether, because they can not be used without a functioning height control of the header.
  • the object is achieved for a generic feeler body in that the feeler body has a division and the parts of the feeler body are connected by a joint. are connected, wherein the hinge has a pivot axis, which allows movement of the probe body in a direction transverse to the working direction.
  • the probe body By the probe body is movable not only in the vertical direction, but also in a direction transverse to the working direction, the transverse forces acting on the probe body reduce considerably.
  • the probe body can deflect when lateral forces act in the lateral direction and thereby reduce the lateral forces.
  • the force peaks acting on the feeler body during operation of the harvesting machine are significantly reduced when the feeler body can deflect forces acting in a direction transverse to the working direction.
  • the working direction of the harvesting machine means the direction in which the working machine is moved toward the crop to be picked up.
  • both the probe body itself and the associated suspension parts can be made less stable.
  • the weight of the component for measuring the ground clearance of the cutting unit and the manufacturing cost of the relevant components significantly reduced.
  • the reaction speed of the probe body increases with changes in the ground clearance, and the signal quality of the probe body improves.
  • the division of the probe has no negative impact on the signal quality, because the vertical mobility of the probe is hardly affected by the additional possibility of movement in a direction transverse to the direction.
  • the replacement of the wear part is also simplified because the probe body no longer has to be removed and mounted on the electronics and the cutting unit, but rather the components that are close to the electronics and cutting tools remain in their installation position on the cutting mechanism when replacing the surface-contacting part and only the joint needs to be disassembled to assemble the replacement part.
  • the first part of the probe body is connected to the pivot axis aligned transversely to the direction of the harvesting attachment and pivotable about this pivot axis in the vertical direction, and the second part of the probe body forms the contact surface for the ground contact and is in a via the joint Direction movable transversely to the working direction.
  • the first part in the vertical direction and the second part in a direction transverse to the working direction are pivotable, there is a defined pivoting behavior. If only the second part, which has the ground contact, can escape in the transverse direction, it remains in the case of a clear pivoting behavior of the probe body in total in the vertical direction over the first part. At the same time it is sufficient to reduce the acting force peaks completely, only to design the second part in the transverse direction evasive, since the first part has no contact with the ground.
  • the movable with its free end second part of the probe body is limited by a tensile strength connected to the header attachment coupling element in its mobility. Due to the limited mobility pivot positions of the second part of the probe are avoided, which in turn can lead to damage, such as too strong angular positions to Vorvortraum.
  • the tensile coupling element may for example consist of a rope or a chain.
  • a sliding bearing is installed in the joint.
  • the plain bearing allows a low-resistance and smooth pivoting movement the transversely to the direction of movement movable part of the probe.
  • the plain bearing also works almost wear-free.
  • the probe body is rigid in the vertical direction.
  • the term "rigid” is to be understood as a stiffness in which, under the action of forces acting on the feeler body in the course of normal operation, no deformations occur which exceed a value of 5% of the structural height of the feeler body in a relaxed position.
  • the probe is not absolutely absolutely rigid, but may have a certain inherent elasticity of the material used and / or its design. However, this should not exceed the specified threshold in order not to falsify the height signal derived from the probe body excessively. However, a certain elasticity can be advantageous in order to be able to reduce acting force peaks.
  • the joint is arranged in the region between the transverse to the direction of the harvesting header aligned pivot axis and the contact point of the probe to the ground. This avoids ground contact of the joint but, on the other hand, limits the pivotability of the feeler in the transverse direction substantially to the portion which is very close to the ground and has ground contact during normal operation. By pivoting only a second part of the probe in the transverse direction, the resulting possible negative influence on the signal quality of the Probe for the relative altitude of the header to the ground kept low.
  • the joint is arranged approximately centrally between the transverse to the direction of the harvesting header aligned pivot axis and the contact point of the probe to the ground.
  • the approximately central position represents a good compromise between a good signal quality, a good reduction of the forces acting on the probe body force peaks, sufficiently large evasive movement possibilities of the second part of the probe in the transverse direction and a protection of the joint from ground contact.
  • a force accumulator is arranged in the joint and / or transversely to the direction of movement movable second part of the probe, which exerts a restoring force at a deflection movement of the transversely movable to the working direction of the second part of the probe body.
  • the second part of the feeler body which is movable in the transverse direction, is pushed back out of the pivoted-out position into the zero position.
  • the energy storage causes the movable second part of the probe to remain as far as possible in an evasive position as long as it is necessary to avoid excessive force peaks.
  • the pivot axis about which is movable in a direction transverse to the working direction of the second part of the probe in the joint is tilted in the working position of the probe against the working direction of the harvester.
