Definitions

  • the present invention relates to a duct plate arrangement for a road finisher according to claim 1 and a road finisher according to claim 12.
  • the working width is the width with which the screed distributes the material on the subsoil.
  • the EP 2 169 117 A1 a corresponding screed with infinitely variable working width.
  • the EP 2 169 117 A1 installable channel plates, which can be provided as part of the auger suspension or connected to it. This creates the possibility of adjusting the effective width of the channel plates, with which they prevent unwanted spreading of material in the direction of travel of the road finisher in front of the auger.
  • such a construction is time-consuming and not very flexible due to the duct plate parts to be installed.
  • the WO2020/009123 A3 a road finisher, wherein the application of material in the direction of travel of the road finisher can be controlled by a pivoting outer bracket.
  • the retaining plate is connected to the tractor via comparatively complex mechanical couplings.
  • the technical problem to be solved is to make the effective width of the channel plate arrangement adaptable to the working width of a screed in a way that is simple for the operator.
  • the duct plate arrangement for a road finisher according to claim 1 or the road finisher comprising a material bunker, a auger, a screed and a duct plate arrangement according to claim 12.
  • the duct plate arrangement comprises an expansion device which comprises a first duct plate which is movably mounted in the horizontal direction with respect to the duct plate arrangement in order to variably adjust the effective width of the duct plate arrangement, and wherein a second duct plate is connected to the first duct plate and the second duct plate is pivotable on first duct plate is arranged to variably adjust the effective width of the duct plate assembly.
  • the first duct plate can in particular be movably mounted transversely to a direction of travel of the road finisher.
  • the second duct plate can be arranged on the first duct plate in particular as pivotable about an axis, wherein the axis can be a vertical axis or a horizontal axis.
  • the duct plate arrangement can be adjusted to the working width of a screed, in particular a screed with a variable working width, with little effort for the operator in terms of its effective width, ie the width with which it can limit the flow of material in the direction of travel.
  • the working width of the screed is understood to mean the width with which the screed spreads the material onto the subsoil or subgrade.
  • the effective width of the duct plate arrangement is to be understood as the width to which the duct plate arrangements limit the flow of material in the direction of travel.
  • This delimitation can usually also be brought about in interaction with lateral delimiting plates of a paving screed, between which the channel plate arrangement extends.
  • this limitation does not have to be perpendicular to the working direction of the road finisher, but can also occur partially obliquely or at a non-perpendicular angle, in particular due to the second channel plate.
  • variable adjustability of the working width of the screed can mean a stepless adjustability or a stepwise variable adjustability of the working width.
  • the extending screed which comprises a base screed (also called screed base body) and screed extending parts arranged thereon.
  • the screed extension parts can usually be moved hydraulically (and steplessly) in relation to the screed body.
  • (rigid) spreader parts can be attached to the outer ends of the extendable plank parts.
  • One or more such widening parts can be attached to the screed extension parts in order to increase the working width of the extending screed.
  • rigid planks which comprise a rigid base plank and widening parts that can be attached to the base plank.
  • the widening parts are usually rigid themselves.
  • hydraulically adjustable extension parts can be arranged as a special configuration of the widening parts, in order to be able to adjust the working width of the rigid screed steplessly and variably at least at the outer ends.
  • the extension attachments are usually always provided as widening parts arranged furthest to the outside (seen from the center of the rigid screed).
  • the duct plate arrangement according to the invention allows, on the one hand, a substantially stepless adjustment of the effective width of the duct plate arrangement and, on the other hand, due to both the horizontal direction of movement of the first duct plate and the pivoting movement of the second duct plate, a variable adjustment of the properties of the duct plate arrangement, which is reflected in particular by the increased variable Width of the channel plate assembly proves to be advantageous.
  • the expansion device comprises an active, in particular a hydraulic and/or pneumatic, traversing device with which the first duct plate can be moved in the horizontal direction.
  • the hydraulic traversing device allows the first duct plate to be moved in a horizontal direction automatically, which is as simple as possible for the operator.
  • the active displacement device can be designed in particular as an actuator.
  • the active displacement device can in particular be designed to bring about the horizontal movement of the first duct plate without manual action, for example depending on a working width of the screed.
  • the expansion device is detachably connected to the duct plate arrangement.
  • the rest of the duct plate arrangement (also duct plate basic arrangement), which in particular can be designed as a duct plate arrangement that has been customary up to now, can therefore also be operated without the expansion device.
  • This allows the road finisher to pass over narrow paths more easily, in that the expansion device is dismantled at least for a short time and reassembled later, which improves the usability of the road finisher even in difficult terrain.
  • the expansion device is arranged on the duct plate arrangement by means of a guide device, the guide device being designed to adjust a position of the expansion device relative to the duct plate arrangement.
  • the duct plate arrangement can have at least two spaced-apart suspensions for detachable connection to the expansion device, which are arranged in a installed state of the duct plate arrangement in a road finisher in a direction transverse to the working direction of the road finisher.
  • the suspension point of the expander By adjusting the suspension point of the expander it can also be achieved that the effective width of the duct sheet arrangement can be increased.
  • This and the previous embodiment can also be advantageously combined and, on the one hand, effect a gradual adjustment of the suspension and thus the initial position of the expansion device and, on the other hand, between these stages, a stepless adjustment of the initial position of the expansion device.
  • This pivoting device can in particular also be designed as an actuator or include one. Hydraulic pivoting allows the operator to easily change the effective width of the duct assembly.
  • the active displacement device and the active pivoting device can be coupled in order to bring about both a displacement of the first duct plate and a pivoting of the second duct plate simultaneously or synchronously.
  • the displacement device and/or the pivoting device can bring about the pivoting and/or the displacement partially automatically or fully automatically, depending on the working width of the screed.
  • One or more sensors such as distance sensors or position sensors, can be provided for this purpose, which determine information about the working width of the screed (for example taking into account rigid widening parts and/or movable extension attachments and/or movable screed extension parts). Based on this information, a control unit can then control the pivoting device and/or the displacement device for the (synchronous) movement (ie pivoting and/or displacement) of the first and/or the second duct plate.
  • the second duct plate is pivotable from an initial position in which it is arranged parallel to the first duct plate, for example, in the direction of the working direction of a road finisher and/or counter to the working direction of the road finisher.
  • the initial position is only arbitrarily specified as being parallel to the first duct plate. Any other initial position is also conceivable here, with starting from this initial position pivoting in at least one direction either in the working direction and/or counter to the working direction being possible according to this embodiment.
  • the duct sheet arrangement can have an effective base width.
  • the duct plate arrangement will also avoid undesired depositing of the paving material on the subsoil or subgrade in the working direction over a certain width, even without an expansion device (then in the sense of a duct plate basic arrangement).
  • the expansion device includes a third duct plate, the position of which is fixed with respect to the expansion device.
  • the expansion device already limits the material being discharged, regardless of the relative position of the first and second duct plates.
  • This can be advantageous in particular with regard to the embodiments of the variable arrangement of the expansion device on the duct plate arrangement in order to avoid gaps in the entire duct plate arrangement (then also including the expansion device).
  • the expansion device is designed for coupled movement with a screed of a road finisher, so that the effective width of the channel plate arrangement can be adjusted depending on a working width of a screed.
  • the working width of the screed correct adjustment of the effective width of the duct plate arrangement can already be implemented.
  • the coupling of the movement of the duct plate arrangement to the movement or working width of the screed can include a mechanical coupling and/or a control-related coupling, for example via a control loop using one or more sensors.
