Definitions

  • the present invention relates to an apparatus for reconditioning, levelling and compacting non-asphalted roads comprising means for reconditioning, means for levelling and means for compacting, where said means are connectable by a frame to a vehicle, and said means for levelling comprises one or more levelling plates.
  • Such roads are for example roads through forests, paths, open spaces in for example parks, roads connecting fields to the nearest highway or farm, roads surrounding lakes or roads following rivers, streams or the like.
  • This kind of wear from vehicles combined with the wear caused by weather can make it unpleasant to drive a vehicle on such roads, and may in some cases furthermore cause damage to vehicles driving at too high speed.
  • An alternative way of maintaining a road is to fill new road material onto the road and then use a scraper unit to distribute the new road material into holes or wheel tracks.
  • the disadvantages of this are that it is costly to fill new road material onto the road, and over time, the level of the road will slowly be raised.
  • the international patent application WO 00/06829 describes a milling, levelling and compacting machine for roads, comprising a rotating cutter with a horizontal axis, one or more levelling plates, and one or more compacting rollers that are connectable by an appropriate frame to a tractor or an equivalent vehicle.
  • the described milling, levelling and compacting machine resolves the aforementioned disadvantages of prior art and it is possible to maintain a non-asphalted road in an acceptable condition, but the machine has several disadvantages such as:
  • milling, levelling and compacting machine is a mechanically complicated and not so efficient machine for reconditioning a road to an acceptable condition.
  • the apparatus comprises means for reconditioning, means for levelling and means for compacting.
  • Said means for reconditioning comprises one or more shares for loosening the upper layer of the road along the entire width of the apparatus followed by
  • Said shares, said levelling plates, and said compacting plates are connected to one single frame or to a combined frame provided by two or more frame parts.
  • Said single/combined frame is provided with an arrangement for connecting to a vehicle, for example a tractor, in such a manner that it is possible to lift the whole apparatus off the ground at one time.
  • Said shares are connected to said frame by a crossbeam where said shares are distributed along said crossbeam, either evenly positioned, or positioned in separate sections that take the position of wheel tracks in the road into account.
  • said shares can be forwardly protruding hooks, protruding teeth, ploughshares or the like or a combination of these. Furthermore said shares can be of a different size depending on the position across said crossbeam.
  • Said means for reconditioning can be height-adjusted to ensure the necessary loosening of the upper layer of the road surface.
  • Said means for reconditioning furthermore acts as a first levelling device because the upper surface is loosened and spread out by said shares.
  • said means for reconditioning are height-adjustable, they can be adjusted to the condition of the existing road or the contour of the material surrounding the road.
  • said means for reconditioning is provided with a mechanical arrangement for regulating the depth of said means for reconditioning. This prevents the means for reconditioning from working itself too deep in for example one side of the road due to a tilt of the road surface.
  • the mechanical arrangement for regulating the depth is either manually operated or automatically operated. If it is manually operated, the maximum depth of the means for reconditioning must be set before using the apparatus.
  • Said one or more levelling plates are crossbeams or plates connected to said frame, which are positioned at a height above the ground allowing a certain amount of loosened road material to be moved, thereby levelling the surface of the road.
  • the height above the ground is attuned to the degree of loosening of the upper layer by said shares, thereby reducing the amount of loose road material that must be pushed in front of the levelling plates.
  • said loose road material is furthermore distributed across the entire width of said levelling plates and left in those parts of the road that need to be filled to reach the level of the surface of the road after said levelling plates.
  • Said one or more compacting plates is a heavy plate that presses down on the levelled surface of the loose road material so as to ensure a hard and even road surface on which any kind of vehicle can drive.
  • Said one or more compacting plates preferably have a width corresponding to or wider than said levelling plates.
  • said means for compacting could be one or more heavy rollers that compact said loose road material.
  • said means for reconditioning, said means for levelling and said means for compacting is each designed in two parts interconnected by a longitudinal hinge-like axis.
  • the gradients of said road surface ensure that rainwater will automatically run off said hard road surface and out to either one side or both sides of the road without causing damage to the road surface.
  • the longitudinal hinge-like axis allows the apparatus to be configured in different manners whereby it is possible to adjust the angle between the two parts of said means for reconditioning, said means for levelling and/or said means for compacting.
  • the road could have:
  • the angle between the two parts of said means for reconditioning, said means for levelling and/or said means for compacting can be adjusted manually and set before the apparatus is used on a part of the road, or the means can be adjusted automatically while using the apparatus.
  • the parts of said means for reconditioning, said means for levelling and/or said means for compacting are provided with means for moving the part in relation to said longitudinal hinge-like axis.
  • Said means for moving could for example be:
  • said means for reconditioning, said means for levelling and said means for compacting in two parts, it is possible to arrange said means at different angles between their respective parts interconnected by a longitudinal hinge-like axis.
  • the levelling plates could have one angle to ensure the distribution of the loosened road material, and the compacting plates could have another angle to provide the desired gradients of the road surface.
  • the apparatus is used for roads.
  • the apparatus is used for drains or sunken roads.
  • said means for reconditioning, said means for levelling and said means for compacting being designed in more than two parts interconnected by more than one longitudinal hinge-like axis.
  • said one or more shares are connected to said frame and tilted inwards, and the shares can furthermore be rotated and tilted outwards when being positioned in a extreme outer position.
  • the shares that are tilted inwards ensure that the loosened road material is moved to the middle of the road so as to ensure that there is enough loose road material to level the road.
  • the shares in the extreme outer position can be rotated and tilted outwards for moving a small amount of the loose road material out into the side of the road. This can be an advantage because often there is more loose road material than what is required for levelling of the road, or there may be a risk of contamination of the road material by soil, weeds, etc.
  • said means for reconditioning furthermore comprises one or more disk coulters, which are positioned in the extreme outer position of the crossbeam of said means for reconditioning.
  • Disk coulters are especially suitable if the apparatus is used along lawns, football pitches and the like where it is desirable to have a sharp edge between the road and the surroundings.
  • said means for levelling comprises two sets of levelling plates that are connected to said frame, and where a first set of levelling plates is positioned in front of a second set of levelling plates and both of said sets are positioned in a forwardly leaning way.
  • the first set of levelling plates is positioned right after the means for reconditioning and provides a rough levelling of the surface and distribution of loose road material, thereby ensuring that holes and irregularities are filled.
  • the second set of levelling plates is positioned at a distance behind the first set of levelling plates and finishes off the levelling of the surface.
  • the height above the road surface of the two sets of levelling plates is different.
  • the height above the road surface of the first set of levelling plates is typically 0-5 cm, and the height above the road surface of the second set of levelling plates is typically 0-3 cm.
  • Both of said sets are positioned in a forwardly leaning way which ensures that the loose road material is more easily moved in front of the levelling plates, and this furthermore provides a compacting effect on the levelled surface.
  • said sets of levelling plates are provided with means for adjusting the heights of said levelling plates above said road.
  • Said means for adjusting could be a spindle operated either manually or hydraulically. If the spindle is operated manually, the height of the levelling plate is set before using the apparatus and kept at the same level throughout the reconditioning of the road. If the spindle is operated hydraulically, the height of the levelling plate can be adjusted during the use of the apparatus.
  • An alternative to a spindle could be a hydraulic cylinder or a mechanical arrangement driven either by a hydraulic unit, an electric unit, a pneumatic unit, or manually.
  • the frame of said apparatus is provided with side plates in the full height of the apparatus.
  • the side plates extend from the lower part of the levelling plates and up to the upper part of the frame.
  • the side plates ensure that loose road material is kept inside the width of the apparatus and used for reconditioning the road surface.
  • said first set of levelling plates in an embodiment of the present invention is provided with one or more upright side plates.
  • the first levelling plates distribute loose road material outwards onto the side plates of the frame, and because the new road material is only distributed outwards onto the upright side plates, a water drain is formed.
  • the water drain is an advantage because the rainwater will run off the road surface due to the gradient of the road surface and into the water drain and to a drain hole, or to a place where it can run into the surroundings without damaging the reconstructed road, or cause environmental damage to the surroundings.
  • the water drain will have the same profile as the road surface which will contribute to transporting the rainwater.
  • said means for levelling furthermore comprises a buffer zone compartment arranged for containing new road material in front of said second set of levelling plates.
  • the buffer zone compartment is the aforementioned compartment formed of the two sets of levelling plates and either the upright side plates or the side plates of the frame.
  • the new road material is filled into the buffer zone compartment and pushed in front of the second set of levelling plates whereby it is added slowly to the road surface.
  • New road material is any loose material, typically sand or gravel which can move under the second set of levelling plates without damaging the road surface provided by the first set of levelling plates.
  • the compacting means is used.
  • said means for compacting is connected to a backside of said second set of levelling plates.
  • the means for compacting supports the weight of the whole apparatus whereby the weight increases the compacting effect of the apparatus. Furthermore the means for compacting functions as an adjustment means for the height above the road surface of the apparatus. This height is determined by the amount of road material moving under the means for compacting and the moist content of the road material.
  • said compacting plates are bended in a slight V-shape, preferably transversely of said longitudinal hinge-like axis where one part of said V-shaped compacting plates is moved parallel to the road surface, and the second part is raised upwards.
  • the raised second part is the part of the V-shaped compacting plates that is connected to the backside of the second levelling plates.
  • the first part of the V-shaped compacting plates By having the second part of the V-shaped compacting plates positioned forwards, the first part of the V-shaped compacting plates will compact the loose/new road material and press it forwards and downwards when moving the compacting means over the road surface, thereby ensuring an efficient compaction of the road surface.
  • said frame is optionally provided with a level tube unit.
  • a level tube unit By having a level tube unit on the frame, it is possible register in-situ the gradient of the existing road whereby it is possible to react to whether the new road surface should have one or more gradients and thereby adjust the angle between the two parts of the means for reconditioning, the means for levelling and/or the means for compacting.
  • the apparatus must be provided with automatic adjustments means so that it is easy for the driver to adjust one or more specific parts of the apparatus from the tractor or vehicle.
  • said level tube unit comprises a transparent plate having at least two layers, a frame, a marker and a liquid, where the frame encloses the transparent plate, and the liquid is filled into the cavity of the transparent plate having at least two layers.
  • the marker for example a tape, marks a horizontal level and is placed outside the transparent plate either on both sides, or on the side facing the person in the tractor or vehicle.
  • the liquid is preferably a coloured liquid.
  • a coloured liquid in any kind of weather condition, makes it easier for the person in the tractor or vehicle to see if the apparatus is operated in a horizontal plane.
  • Fig. 1 shows an apparatus 1 comprising means for reconditioning 2, means for levelling 3 and means for compacting 4, where said means are connectable by a frame 5 to a vehicle 6.
  • Said means for reconditioning 2 comprises one or more shares 7, and said means for levelling 3 comprises one or more levelling plates 8a, 8b and said means for compacting 4 comprises one or more compacting plates 9.
  • Said shares 7 are connected to the frame 5 by the crossbeam 10 and positioned in the front of the apparatus and thereby dug into the road surface 11 for losing an amount of road material 12.
  • a compacting plate 9 for compacting the road surface 11 is positioned, said road surface having been levelled by the two sets of levelling plates 8a, 8b.
  • the frame 5 is connected to the vehicle 6 by a hydraulic cylinder 13 and a set of lift arms 14 thereby allowing the vehicle 6 to raise or lower the whole apparatus 1.
  • the compacting plates 9 rest on the road surface 11 and support the weight of the apparatus 1, thereby adding extra weight to the compaction of the loose road material 12.
  • Fig. 2 shows the frame 5 from a perspective view of the person (not shown) positioned inside the vehicle (not shown).
  • a 3-point arrangement 16 for connecting the frame 5 to the vehicle (not shown) is mounted on the front end 5a of the frame 5.
  • a level tube unit 17 is mounted on the rear end 5b of the frame 5 for controlling the gradient of the frame 5 under the reconstruction of the road surface (not shown).
  • a first set of levelling plates 8a is positioned and subsequently a second set of levelling plates 8b. Together with the side plates 15, the levelling plates 8a, 8b form a compartment 18 wherein it is possible to fill new road material.
  • Fig. 3 shows a rear view of the means for reconditioning 2, where the shares 7 are connected to the frame 5 via crossbeam 10.
  • the shares 7 are shown as being positioned in a separate section to allow for wheel tracks (not shown).
  • the shares 7c are tilted inwards to gather the loose road material (not shown) into the middle of the road (not shown).
  • the shares 7a, 7b are positioned in an extreme outer position and tilted outwards to push excess loose road material (not shown) outside the road (not shown).
  • Fig. 4 shows a rear view of the apparatus 1 while reconstructing road surface 11 so that it will have two gradients and slope from the middle of the road surface 11 outwards towards the water drains 20.
  • the form of the road surface 11 ensures that rainwater runs off the road surface 11 and into the water drains 20 without damaging the road.
  • the two parts 9a, 9b of the means for compacting 4 are interconnected by a longitudinal hinge-like axis 19.
  • the level tube unit 17 is mounted on the rear end of the frame 5 facing the person in the vehicle (not shown).
  • the side plates 15 are mounted in connection with levelling plates 8b, and they extend from the base of the levelling plates 8b to the frame 5.
  • Fig. 5 shows how the upright side plates 21 are positioned inside side plates 15 for forming a water drain 20, which can be formed by adding new road material into compartment 18 and then moving the apparatus 1 along the road 22.
  • the loose road material 12 from the existing road 22 is distributed outwards to the side plates 15, while at the same time, the new road material from compartment 18 is only distributed outwards to the upright side plates 21.
  • Fig. 6 shows a perspective view of the means for compacting 4 where the compacting plates 9 are connected to a backside of the second set of levelling plates 8 and formed in a slight V-shape.
  • the bend line 24 is preferably transverse of said longitudinal hinge-like axis.
  • the front part 9c of the V-shaped compacting plates 9 is raised in comparison to the end part 9d of the V-shaped compacting plates 9, which are moved parallel to the road surface.
  • the gap between the front part 9c and the road surface ensures an efficient compacting because the loose road material 12a passed under the levelling plate 8b will be pushed forwards and downwards.
  • Fig. 7 shows an arrangement 30 for regulating the depth of the reconditioning means (not shown) which comprises plates 31 and profiles 32.
  • the profile 32 is connected to the frame 5, and the profile 33 is movably mounted inside the profile 32. At its lower end, the profile 33 is connected to the shares 7, and at its upper end to a polygonal plate 31. The shares 7 can be lifted by moving the profile 33.
  • the plates 31 can be rotated around the axes 35 so that the lower edge parts of he plates 31 abut against the upper edge of the profile 32 whereby the shares 7 are prevented from digging further into the upper layer of the road.
  • the polygonal shape of the plates 31 ensures different depth positions of the reconditioning means.
  • the plates are rotated around the axis 35 to set the maximum depth of the shares 7.
