Definitions

  • the present invention relates to a clearing blade for a vehicle.
  • Plow blades for example for clearing snow or removing other materials from a subsurface
  • Plow blades are known per se.
  • the clearing blade according to the invention comprises an interface for attaching the clearing blade to a vehicle.
  • the vehicle can be, for example, a front loader or any other vehicle to which the clearing blade can be attached by means of the interface.
  • the clearing blade can, for example, be screwed or otherwise fastened to a wide variety of vehicles via the interface.
  • the clearing blade also comprises at least a first blade and a second blade, which are connected to one another via a swivel joint, the axis of rotation of which runs in the vertical direction of the clearing blade.
  • the clearing blade comprises an adjustment device for pivoting the blades about the axis of rotation.
  • the adjustment device can, for example, have a hydraulic mechanism, for example in the form of hydraulic cylinders or the like, in order to pivot the signs about the axis of rotation.
  • the clearing blade can also have a corresponding interface via which, for example, hydraulic cylinders can be connected to a hydraulic circuit of a vehicle, so that the adjustment device can be supplied with energy via the relevant vehicle to which the clearing blade is currently attached.
  • the clearing blade comprises a rubber strip which is fastened to the shields and protrudes downwards, the neutral fiber of which runs through the axis of rotation of the swivel joint.
  • the rubber strip thus forms the lowest area of the clearing blade. If the clearing blade is used to clear a subsurface, the clearing blade with the rubber strip rests on the relevant subsurface.
  • the signs are made in particular from a rigid material, for example they can be made from steel or another metallic alloy.
  • the rubber strip In the transverse direction of the clearing blade, the rubber strip is so wide or so long that it is arranged below all the blades of the clearing blade. In particular, it can be provided that the rubber strip extends over the entire width of the clearing blade and thus over the entire width of the blades of the clearing blade.
  • the rubber strip together with the signs can be pivoted particularly easily.
  • the rubber strip hardly or not at all deviates transversely to the axis of rotation when the signs are pivoted.
  • the rubber strip is hardly or not at all deflected transversely to the axis of rotation when the signs are pivoted to one another.
  • the clearing blade With the clearing blade according to the invention, it is therefore possible to pivot the at least two blades relative to one another in a particularly simple manner, the rubber strip, following the pivoting movement, bending without the rubber strip in the area of the swivel joint or the axis of rotation being transverse to the axis of rotation is deflected. It is therefore only necessary to provide a single continuous rubber strip instead of providing a separate rubber strip for each sign.
  • the clearing blade has a third blade.
  • the second shield is arranged centrally between the first shield and the third shield in relation to the transverse direction of the clearing shield.
  • the second shield is connected to the third shield via a further swivel joint, the axis of rotation of which runs in the vertical direction of the clearing shield.
  • the rubber strip is attached to all three signs, with the neutral fiber of the rubber strip running through the axes of rotation of the two swivel joints.
  • the second shield thus forms the middle shield, the first shield forming a left shield, for example, and the third shield forming a right shield.
  • the left and right shields can be folded up to the middle shield if necessary.
  • the adjusting device has at least one hydraulic cylinder for pivoting at least one of the signs.
  • a respective hydraulic cylinder can be provided, for example, in order to pivot the left or right sign between a folded-in or unfolded position.
  • the rubber strip is attached to the signs in such a way that a relative movement between the rubber strip and the signs is prevented.
  • the rubber strip can be permanently and reliably attached to the signs. The length of the rubber strip always remains the same.
  • the rubber strip is screwed to the signs.
  • elongated holes are not provided either in the rubber strip or in the signs.
  • only round bores are provided so that the rubber strip is screwed to the signs without play. Even when the signs are pivoted relative to one another, there is no translational movement of the rubber strip relative to the signs.
  • the rubber strip is connected to the signs by means of respective rigid strips.
  • the rigid strips can be, for example, flat profiles that, for. B. are made of steel. Other rigid materials are also possible.
  • the rubber strip can be connected to the signs in a particularly reliable and durable manner.
  • the rigid strips can, for example, be provided with several holes, as can the rubber strip and the respective signs. For example, screws can be inserted through the bores to connect the rubber strip to the signs with the intermediary of the rigid strips.
  • a further possible embodiment of the invention provides that the swivel joint and / or the further swivel joint is formed by respective tubes which are fastened to the signs and which are connected to one another by respective connecting bolts. This results in particularly stable swivel joints so that the signs can remain permanently connected to one another.
  • a clearing blade 10 is shown in perspective view in FIG Figure 1 shown.
  • the clearing blade 10 comprises a middle blade 12, a left blade 14 and a right blade 16.
  • the middle blade 12 is connected to the left blade 14 and the right blade 16 via respective pivot joints 18, 20.
  • the middle shield 12 also includes an interface 22 for attaching the clearing shield 10 to a vehicle.
  • the clearing blade 10 can be attached to a front loader via the interface 22.
  • the clearing blade 10 can also be attached to all possible other vehicles, the interface 22 being suitably designed accordingly.
  • the respective axes of rotation of the swivel joints 18, 20, which are not identified in greater detail here, run in the vertical direction of the clearing blade 10.
  • the left blade 14 and the right blade 16 can be folded in and out.
  • a continuous rubber strip 26 is arranged below the signs 12, 14, 16 or in a lower region of the signs 12, 14, 16.
  • the rubber strip 26 projects over the signs 12, 14, 16 downwards, thus forms the lowermost area of the clearing blade 10.
  • the rubber strip 26 is connected to the respective signs 12, 14, 16 through the intermediary of respective strips 28.
  • the strips 28 can be, for example, flat profiles made of steel or the like.
  • the strips 28 have respective bores 30, although not all bores have been provided with reference symbols for the sake of clarity.
  • the rubber strip 26 has respective bores at corresponding points, as do the signs 12, 14, 16. Through these bores 30, for example, screws, bolts or the like can be inserted around and through the strip 28, the rubber strip 26 fixed to the respective signs 12 , 14, 16 to connect.
  • the swivel joints 18, 20 are formed by respective tubes 32 which are fastened to the shields 12, 14, 16 and which are connected to one another by respective connecting bolts 34.
  • the tubes 32 are aligned in the vertical direction, wherein, for example, the respective upper and lower tubes 32 can be fastened to the outer shields 14, 16, wherein the respective central tubes 32 can be fastened to the central shield 12.
  • Other variations are of course also possible.
  • FIG 2 the clearing blade 10 is shown in a plan view, once in an overall view and once an area A is shown in detail.
  • a neutral fiber 36 of the rubber strip 26 is indicated schematically.
  • the rubber strip 26 is arranged in relation to the shields 12, 14, 16 and to the joints 18, 20 that the neutral fiber 36 of the rubber strip 26 runs through the respective axes of rotation of the swivel joints 18, 20.
  • the axis of rotation of the swivel joint 18 in the detailed view A has been provided with the reference symbol 38.
  • FIG 3 a part of the clearing blade 10 is shown in a plan view, with a region B being shown enlarged from the same perspective.
  • the area B is the other swivel joint 20, which connects the middle shield 12 and the right shield 16 to one another in an articulated manner.
  • the neutral fiber 36 also passes through the axis of rotation 40 of the further swivel joint 20 runs.
  • the neutral fiber 36 always remains in the axes of rotation 38, 40 of the swivel joints 18, 20.
  • the rubber strip 26 can thus be firmly connected to the respective shields 12, 14, 16 without that the rubber strip 26 deviates transversely to the axes of rotation 38, 40 when the outer shields 14, 16 are pivoted to the central shield 12.
