Definitions

  • the present invention relates to a bucket-like tool adapted to remove gravel or the like from a track or a gutter defined between two side walls or side-limits i.e. the tool prepare a track or gutter with a well-defined depth and/or width.
  • the tool is normally handled by an enginepowered machine such as a loader, skid loader, tractor, or the like.
  • Bucket-like tools for skimming and scraping are known.
  • the terms scraping and skimming will be used interchangeably in the present document to describe an operation wherein a "cut" of material of predetermined depth is removed from a surface over which the bucket is moved.
  • the known bucket-like tools are generally designed for handling and moving or transporting large amounts of bulk material, and the tools are often used for many different tasks for which they are not optimally designed.
  • conventional bucket designs when the primary blade of the bucket is used for scraping operations, the blade may tend to dig into the material surface when the blade is advanced in a forward direction of the bucket, providing uneven material removal.
  • the bottom of the bucket is typically placed on the ground surface and the bucket is dragged "backward" to pull earth and material behind the bucket.
  • Typical buckets do not allow for significant material to be accumulated behind the bucket when used in this manner, and the rear surfaces of conventional buckets are not designed and reinforced for extended use in this manner.
  • the bucket may be raised and tipped forward such that the bottom of the bucket is generally vertical to the ground surface and then lowered until the front blade engages the ground. The bucket is then dragged backwards to pull earth and soil behind the bucket for grading the material surface.
  • Such operation places significant torque on the bucket and excessive wear and tear on the hydraulic cylinders that control the bucket rotation.
  • the bucket-like tool according to the present invention does not require movable parts, the tool may be adapted in dimensions such as depth and width, however, this adaptation does not necessarily arise from parts being movable during operation.
  • an object of the present invention relates to a tool making the process of planing or removing material from a track or gutter in a predetermined depth a faster and much cheaper process.
  • one aspect of the invention relates to a tool for removing material at a predetermined depth during operation
  • the tool comprises a carrying surface (1) having a front edge (2), during operation the front edge (2) and the carrying surface (1) extend in a horizontal direction and is moved forward, and material is accumulated on or passes over the carrying surface (1), side parts (3) defining the width of the carrying surface (1) and having a height h sp , and fastening means (4) configured to fix the tool to a powered machine during operation
  • the tool comprises at least one elevation part (5) extending horizontally from a side part (3) in a direction away from the centre of the front edge (2), the elevation part (5) comprises a lower edge (6), the vertical distance h v between the lower edge (6) and the front edge (2) determines the predetermined depth in which material is removed.
  • the tool may comprise at least two elevation parts (5) extending horizontally from opposite side parts (3).
  • the at least two elevation parts (5) may comprise a front surface facing in the direction of movement which front surface extends in an angle ⁇ relative to the front edge (2) or which front surface at least in one point has a tangent extending in an angle ⁇ relative to the front edge (2), where 90° ⁇ ⁇ ⁇ 180°, preferably 120° ⁇ ⁇ ⁇ 150°, or 40° ⁇ ⁇ ⁇ 50°.
  • the fastening means (4) may be a standard coupling / holder / bracket adapted to connect to a working arm of an excavator or backhoe or tractor and the fastening means (4) may be positioned on a top surface (10) of the tool.
  • the tool may be bucket-like having an open front end along the front edge (2) and a closed backwall (11) opposite the front edge (2).
  • a closed backwall 11 may be constituted of a wall without openings or with openings so small that material to be removed may not pass through the openings, i.e. material is retained inside the volume of the tool.
  • each side part (3) may be constituted of walls without openings or only comprise openings which are too small to allow passage of the material to be removed or planed.
  • the elevation part(s) (5) may extend in a direction away from a centre line C of the front edge (2) in a distance d being at least 0.2 x w, where w is the width of the carrying surface (1), preferably d > 0.3 x w.
  • the elevation part(s) (5) may be attached/fixed to the side part(s) (3) by fastening means, which fastening means may be either releasable and variable, or permanent and invariable, the fastening means may comprise corresponding parts of respectively the elevation part(s) (5) and the side part(s) (3).
  • the elevation part(s) (5) may extend in an area (7) beside and along the side part(s) (3) of the tool, optionally the area (7) comprises a horizontal surface which may constitute an extra collection surface for material passing over the side part(s) 3 or elevation part(s) 5.
  • Another aspect of the present invention relates to a method for skimming or scraping a track or gutter of predetermined depth using a tool according to the first aspect.
  • the track or gutter from which material is removed at one side or at both sides are lined with an edge of a hard material such as hardened filling material such as asphalt or concrete or the like, and during operation the lower edge (6) of at least one elevation part (5) slides on top of the upper surface of the edge of hard material.
  • a hard material such as hardened filling material such as asphalt or concrete or the like
  • the present invention relates to s tool for removing material at a predetermined depth during operation.
  • a first embodiment of a tool according to the invention is shown in figs. 1 and 2 and a second embodiment is shown in figs. 3 and 4 .
  • a tool in general, comprises a carrying surface 1 comprising a front edge 2 and during operation the front edge 2 and the carrying surface 1 extend in a horizontal direction and is being moved forward.
  • the carrying surface 1 of the tool is kept in a general horizontal position, partly because the length of the carrying surface 1 supports a horizontal forward moving position and partly according to the skills of the operator.
  • Material may be accumulated on or passing over the carrying surface 1, if the material accumulates on the carrying surface 1, then the carrying surface 1 may comprise a backwall 11 or similar material-stop which backwall 11 together with side parts 3 prevents material from falling of the carrying surface 1.
  • the back wall 11 may be constituted of a wall without openings or with openings so small that material to be removed may not pass through the openings.
  • the tool may then be operated as a bucket and be used to remove material from a site.
  • the carrying surface 1 may have no backwall 11 or have a backwall with openings large enough to allow material to pass through and then the tool may function as a planner.
  • the side parts 3 define the width of the carrying surface 1, and the side parts 3 are during operation in a vertical position or at least in a position where they are partly vertical, in an operational position, the side parts 3 have a height h sp , i.e. meaning that the side parts 3 extend the length h sp , in vertical direction.
  • the height h sp of a side part 3 is defined as the projection in the vertical direction at a position of the tool where the front edge 2 extend in a horizontal direction as normally during operation.
  • the side parts 3 will be constituted of walls without openings or comprise openings which are too small to allow passage of the material to be removed or planed. Side parts 3 without openings or with small openings force the material entering onto the carrying surface 1 over the front edge 2 to remain on the carrying surface 1 inside the volume of the tool, if the tool has a backwall 11, or to leave through a backward opening if the tool has no backwall 11. If the tool has a backwall 11, the tool may be used as a bucket to remove material.
  • the tool also comprises fastening means 4 configured to fix the tool to a powered machine during operation, and normally, the fastening means 4 is a standard coupling or holder or bracket adapted to connect to a working arm of an excavator or backhoe or tractor and normally the fastening means 4 are fixed to a top surface 10 of the tool.
  • the fastening means 4 is a standard coupling or holder or bracket adapted to connect to a working arm of an excavator or backhoe or tractor and normally the fastening means 4 are fixed to a top surface 10 of the tool.
  • a tool according to the invention comprises at least one elevation part 5 extending horizontally from a side part 3 in a direction away from the centre of the front edge 2, each elevation part 5 comprises a lower edge 6.
  • the vertical distance h v between the lower edge 6 and the front edge 2 determines the predetermined depth in which material is removed.
  • the significant advantage obtained by use of a tool according to the invention is due to the presence of a vertical distance h v as this makes it possible to the operator to remove a precise layer of material in a track or line very fast.
  • a filling material such as asphalt in order to lay pipes for water, heat or the like, then the filling material must be re-applied after having positioned the pipes and refilled with loose material.
  • the filling material such as asphalt is expensive and creating a track having a very precise depth may therefore reduce the cost for repairing the filling material significantly.
  • the track or gutter from which material is removed at one side or at both sides may be lined with an edge of a hard material such as hardened filling material e.g. asphalt or concrete or the like, and during operation the lower edge 6 of one or more elevation parts 5 slides on top of the upper surface of the edge of hard material.
  • a hard material such as hardened filling material e.g. asphalt or concrete or the like
  • the lower edge 6 may be adapted to the material constituting the edge of hard material, e.g. the lower edge 6 may comprise a roller or wheels, or a smooth sliding material such as Teflon or the complete elevation part 5 may be constituted of a soft material such as wood in order to reduce scratch marks and wear on the upper contact surface of the edge of hard material.
  • the tool may comprise at least two elevation parts 5 extending horizontally from opposite side parts 3. Two horizontally oppositely extending elevation parts 5 may keep the tool in balance when operating in a track having supporting surfaces on each side of the tool during operation.

  • the front surface may alternatively be curved e.g.
  • the front surface may at least in one point have a tangent extending in angle ⁇ relative to the front edge 2, where 90° ⁇ ⁇ ⁇ 180°, preferably 120° ⁇ ⁇ ⁇ 150°, or 40° ⁇ ⁇ ⁇ 50°.
  • the front surface may have a height h ep being at least h sp /3, or at least h sp /2 or at least h sp ⁇ 2 3 , and/or height of the surface hep, h ep ⁇ h sp .
  • the length of the front surface I s i.e. the length from the side part 3 to the end furthest away from the side part 3 is compared to the length I fe of the front edge 2: I s ⁇ 1 ⁇ 2 ⁇ I fe .
