Definitions

  • the present invention relates generally to an excavator bucket, and more particularly to an excavator bucket which is intended to coact fixedly but detachably with the excavator arm of an excavating machine.
  • the bucket may advantageously be secured to the arm by means of known quick-coupling devices, and movement of the arm and movement of the bucket, through its pivotal attachment to the arm, are controlled in a known manner with the aid of hydraulically operable piston-cylinder devices, in the following abbreviated to hydraulic piston device.
  • the holder arm can be pivoted through an angle of 120°, between a downwardly swung position in which the brush is caused to rotate and therewith sweep away the thin layer of filling material which remains subsequent to shovelling away filling material from a buried conduit,
  • a qualified technical problem is one of providing a solution for fulfilling the aforesaid purpose of removing a residual layer of material covering a conduit subsequent to shovelling away filling material, so as to expose a conduit or conduits with the aid of an excavating bucket produced as a complete unit and capable of being readily switched between different tractors with the aid of quick-coupling devices, at the same time as a special- duty bucket can be replaced with a conventional bucket when required.
  • Another technical problem is one of realising the advantages which an excavating bucket having a rota ⁇ table brush will afford when the bucket is caused to coact with a so-called rotor tilt.
  • a technical problem resides in providing a bucket construction in which a rotatable brush can be caused to take a first position in which the brush is located within he * bucket and a second position in which said brush extends from said bucket, where in the first inactive position of the brush said brush is located within a rearwardly open space formed in the rear part of the bucket. It will also be seen that a technical problem is one of realising the advantages afforded by permitting the rotatable brush to be carried by an arm, preferably by two arms, which is or are pivotally attached to the bucket wall at its upper, rear part.
  • Another technical problem is one of realising the technical advantages afforded when the hydraulic piston is caused to coact with the arm via a slot which en- ables the rotatable brush to travel freely within narrow limits, thereby to improve shovelling-away of light filling materials and therewith expose the conduit.
  • a further technical problem is one of providing a bucket which is constructed in a manner which will fulfil the aforesaid purpose, and to realise the sig ⁇ nificance of enabling the brush to rotate from the first to the second position in a 90° pendulating movement in a direction which conforms with a line that constitutes an extension rearwardly of the lower ⁇ most planar part of the bucket.
  • Another technical problem is one of realising within which angular values the first and the second position shall be selected in relation to a line that extends perpendicularly to the lowermost planar part of the bucket. It will also be seen that a technical problem is one of realising the significance that selection of the dis ⁇ tance between the pivot axis of the arm and the rota ⁇ tional axis of the brush has on the ability to ful- fill the aforesaid purpose.
  • the present invention provides an excavating bucket of particular configuration which is not only well adapted for coaction with an excavating arm forming part of the excavating machine, via known coupling means, but which is also adapted to provide a bucket whose purpose is to remove thin layers of material that remain above a conduit subsequent to shovelling away filling material above said conduit, such as to expose one or more conduits.
  • the inventive construction utilizes a known rotatable brush which, in accordance with the invention, is arranged for movement between.a first position in which the brush is located within the bucket and a second position in which the brush is extended from the bucket, wherein when occupying said first position, the brush is located within a rear ⁇ wardly open space formed in the rear part of the bucke .
  • the rotatable brush is carried by one or two arms which are pivotally connected to the upper, rear wall part of the bucket, and in that a drive motor is connected to the arm such as to cause the brush to swing in one of two directions, through the intermediary of transmission means.
  • a hydraulic piston device is mounted within the upper part of the bucket and caused to coact with the arm or arms through the intermediary of a slot.
  • pivotal movement of the brush from the first to the second position is a pendulating movement with a movement direction that conforms with a line constituting an extension of the lowermost planar part of the bucket, and that the angular value between the first and the second position is smaller than 110° and greater than 60°, preferably within the range 100°-80°.
  • the angular values shall divide so as to be halved on each respective side of a line which extends perpen ⁇ dicularly to the lowermost planar part of the bucket.
  • the distance between the pivot axis of the arm and the rotational axis of the brush is between 1.5 and 0.7 times the brush diameter, prefer ⁇ ably between 1.0 and 0.8.
  • the hydraulic piston device is arranged to coact with the arm at a point which is located above the pivot axis of the arm and at a small distance between said point and said pivot axis, so as to obtain a large pendulum movement with a small piston movement.
  • Figure 1 is a side view of a tractor whose excavating arm coacts with an inventive excavating bucket
  • Figure 2 is a sectional view of the bucket, and shows a rotatable brush moved to a first position in which the brush is folded into the bucket;
  • Figure 3 is a corresponding sectional view of the bucket, with the bucket rotated through 45° and the rotatable brush shown in its second positon in which it extends from the bucket.
  • FIG. 1 is a very simplified illustration of a tractor 1 having a known excavator unit comprising, inter alia, an excavating arm 2.
  • the free end 2a of the arm 2 coacts with an excavating bucket 3 through the inter ⁇ mediary of a coupling 4, said bucket being constructed in accordance with the present invention.
  • Figure 1 illustrates the rotatable brush in a second position ( Figure 3) in which it extends from the bucket for the purpose of removing a layer of material C that remains above a conduit B subsequent to shovelling away filling material A, therewith to expose the conduit B.
  • the conduit B may be one or more electrical conductors, or cables, one or more gas conduits, one or more water conduits, etc.
  • Figure 2 illustrates the bucket 3 with the rotatable brush folded into its first position, said bucket being shown in a slightly larger scale and with a part fur ⁇ ther enlarged.
  • the rotatable brush 5 is held firmly by an arm 6 which is positioned centrally in the bucket and which coacts with a hydraulic motor 7 by means of which a transmission 8 is caused to drive the rotatable brush 5 in one of two rotational directions.
  • the re ⁇ quisite changeover device or switch is not shown, but may be electrical.
  • the arm 6 is pivotally connected to the bucket by a pivot pin 9 and the arm 6 is held in the position shown in Figure 2 with the aid of a hydraulic piston device 10.
  • the rotatable brush 5 can be moved to a first position, shown in Figure 2, in which the brush is located in the bucket, and a second position, according to Figure 3, in which the brush is extended out f om the bucket.
  • the brush In the first brush position, shown in Figure 2, the brush is located within a rearwardly open space 3a formed in the rear part of the bucket. This space is defined forwardly by an intermediate wall 3b and separates the forwardly open space 3c of the bucket intended for shovelling filling material.
  • the arm 6 is pivotally mounted to the wall 3e of the bucket 5 and to its upper rear ' part.
  • the hydraulic piston device 10 is mounted within the upper part 3f of the bucket and coacts with the arm 6 at 11.
  • the uppermost part of the arm is, in this case, provided with a pin 11.
  • the pin 11 is located in a slot 12 and enables the brush 5 to swing backwards and forwards when the brush is used within the angular values applicable between the position shown in Figure 2 and the position shown in Figure 3.
  • the hydraulic piston device 10 is positioned parallel with the lower ⁇ most planar part 3g of the bucket and is secured in a known manner.
  • rotation of the brush 5 from the first position in Figure 2 to the second position in Figure 3 is a pendulum-like movement with the direc ⁇ tion of movement following a line that constitutes an imaginary extension of the lowermost planar part 3g of the bucket.
  • the angular value between the first and the second positions is selected to 90° and the brush will swing through 45° on respective sides of a line 15 which extends perpendicularly to said extension of the planar part 3g.
  • the distance between the pivot axis 9 of the arm 6 and the rotational axis 16 of the brush 5 is 0.9 times the diameter of the brush.
  • the hydraulic piston 10 is intended to coact with the arm at a point which is located above the pivot axis 9 of the arm 6. This distance shall be small, so as to afford a large pivotal movement of the brush 5 in response to a small piston movement of the hydraulic piston device 10.
