Definitions

  • the present invention relates to a plow blade for a vehicle.
  • Clearance blades for example for clearing snow or for removing other materials from a surface
  • Clearance blades are known per se.
  • DE202011050562U describes a clearing blade with the features of the preamble of claim 1.
  • 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 using the interface.
  • the plow blade can be screwed onto a wide variety of vehicles via the interface or attached in some other way.
  • the clearing blade also includes at least a first shield and a second shield, 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 includes an adjusting device for pivoting the blades about the axis of rotation.
  • the adjusting 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 adjusting device can be supplied with energy via the vehicle in question to which the clearing blade is currently attached.
  • the clearing blade includes a rubber strip that is attached to the blades and protrudes downwards, the neutral fiber of which runs through the axis of rotation of the swivel joint.
  • the rubber strip forms the lowest area of the plow blade. If the plow blade is used to clear a surface, the plow blade rests with the rubber strip on the surface in question.
  • the signs are in particular made of a rigid material, for example they can be made of steel or another metallic alloy.
  • the rubber strip is designed to be so wide or long that it is arranged below all of 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.
  • a further possible embodiment of the invention provides that 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 blade.
  • the second shield is connected to the third shield via another swivel joint, the axis of rotation of which runs in the vertical direction of the clearing blade.
  • the rubber strip is attached to all three shields, with the neutral fiber of the rubber strip running through the pivot axes of the two swivel joints.
  • the second shield forms the middle shield, with the first shield forming, for example, a left shield and the third shield forming a right shield.
  • the left and right shields can be folded into the middle shield if necessary.
  • the rubber strip forms the lowest area of the plow blade.
  • the fact that the neutral fiber of the rubber strip runs through the axes of rotation of the two swivel joints results in the positive effect that the rubber strip is not deflected transversely to the respective axes of rotation when the signs are pivoted relative to one another. This in turn results in a completely controlled bending or deformation of the rubber strip when the respective signs are pivoted towards each other. It is therefore not necessary to provide a respective rubber strip for each sign. Instead, it is very simple to provide a single rubber strip for all signs, which bends accordingly following the pivoting movements of the signs.
  • a further possible embodiment of the invention provides that the adjusting device has at least one hydraulic cylinder for pivoting at least one of the signs.
  • a respective hydraulic cylinder can be provided 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. This means that 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.
  • a clearing blade 10 is shown in a perspective view Figure 1 shown.
  • the clearing blade 10 includes a middle shield 12, a left shield 14 and a right shield 16.
  • the middle shield 12 is connected to the left shield 14 and the right shield 16 via respective swivel joints 18, 20.
  • the middle shield 12 also includes an interface 22 for attaching the plow blade 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 kinds of other vehicles, with the interface 22 being able to be designed to suit.
  • a continuous rubber strip 26 is arranged below the signs 12, 14, 16 or in a lower area of the signs 12, 14, 16.
  • the rubber strip 26 projects downwards beyond the signs 12, 14, 16, thus forming the lowest area of the clearing blade 10.
  • the rubber strip 26 is connected to the respective signs 12, 14, 16 by means 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 for the sake of clarity not all bores have been provided with reference numbers.
  • the rubber strip 26 has respective holes at corresponding locations, as do the signs 12, 14, 16. For example, screws, bolts or the like can be inserted through these holes 30 in order to secure the rubber strip 26 firmly to the respective signs 12 by means of the bar 28 , 14, 16 to connect.
  • FIG 2 the clearing blade 10 is shown in a top view, once in an overall view and once an area A is shown in detail.
  • area A there is the joint 18, which connects the left shield 14 to the middle shield 12 in an articulated manner.
  • a neutral fiber 36 of the rubber strip 26 is indicated schematically both in the overall view and in the detailed view A.
  • the rubber strip 26 is arranged in relation to the signs 12, 14, 16 and the joints 18, 20 in such a way 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 was provided with the reference number 38 in the detailed view A.
  • FIG 3 a part of the clearing blade 10 is shown in a top view, with an area B being shown enlarged from the same perspective.
  • 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 moves transversely to the axes of rotation 38, 40 when the outer shields 14, 16 are pivoted towards the middle shield 12.
