Definitions

  • the present invention relates to a bucket for earth working, loading and transporting machinery and devices according to the preamble of claim 1. It is well known that the major part of earth working operations are accomplished with use of tractor propelled digging devices, such as all kinds of excavators equipped with buckets.
  • WO 90/10756 discloses an impact bucket apparatus having an impact hammer being impact coupled to a cutting edge assembly to fracture rock and other hard material. In such a configuration, the operation radius of said cutting edge is however limited by the bulkiness of the bucket.
  • the invention creates means which allow breaking of hard soil while the material flows and is heaped into the bucket simultaneously.
  • the same bucket also in a further step can load the material or move it to other locations on the site.
  • a bucket for earth working machinery said bucket being provided with at least one integral hydraulic hammer device including a chisel and positioned at the bottom of said bucket and securely affixed to it, means being provided to activate said hydraulic hammer whenever the cutting edge of said bucket encounters an obstacle which exerts pressure on the bucket larger than the pressure originating from the action of the engine of an earth working machinery having said bucket mounted on it and possibly other power units actuating the respective equipment, characterized in that said bucket being further equipped with means which enable partial release of said hammer from said bucket.
  • the said actuating means would comprise a sensor of generally known type which - whenever the bucket encounters an obstacle of the kind referred to issues a command to the hydraulic hammer to start operation of fragmentation of the obstructing rock formation by direct penetration of the chisel and thus applying original power of the hammer to full extent.
  • the said sensor may be of electric, electronic or electro/hydraulic type.
  • the hammer In the event that continuous hammer work is required in standard hydraulic hammer operation, the hammer is released from its position so that it extends from the bucket. In that case it is preferred to operate in two separate steps i.e. the breaking and the bucket filling operation as compared to the one step operation which simultaneously breaks and fills the bucket. In that case there would be no operation limitation to the bucket and/or to the hammer: the bucket can operate as a breaking and filling device simultaneously, and at loading as a further step, or this process can be divided for use in certain applications as will be explained further on.
  • the bucket After using the hammer in the position of (removed from bucket bottom) standard hydraulic hammer while sliding back the hammer mechanism to former inner position, the bucket can be used to load or move the material which had been broken in the extended position.
  • Fig. 1 is a fragmentary, partly sectional view of an impact bucket in the cavity of which an hydraulic hammer is placed.
  • Fig. 2 is a diagrammatic view of the working elements of an arrangement including the bucket of an earth working and moving assembly, provided with a hammer.
  • Figs. 3, 4 and 5 show details.
  • Fig. 1 there is shown the conventional bucket B linked to a pair of arms A which extend in a known manner from any excavators or backhoe tractor or wheel loader or other truck and wheel excavation machine excavators.
  • the bucket is shown in a position of having penetrated the soil S and having met an agglomeration of rocks R.
  • On the bottom wall of bucket B is positioned the hydraulic hammer H, from the leading end of which extends a chisel C.
  • a signal establishing this fact is transmitted (as will become clear later) to a command center, whereupon a command is issued which via hose HS activates the hammer H to break up and fragmentize the rock formation R.
  • the operation of the hammer will automatically stop when no longer needed.
  • Figs. 2, 3, 4 and 5 illustrate the manner in which hammer H is held in and released from bucket B, when the separate operation of the hammer is required for hard rocks or for demolition jobs.
  • Hammer H is mounted with a pair of guide rails 3 and 4, and secured by means of two hydraulic pistons 5 which when activated causes attraction of a pin 6.
  • the hammer will then slide out of the bucket by its own weight.
  • pin 6 will penetrate into hole 7 enabling working with the now separate hammer in the extended position.
  • the hammer is placed back to its inner position in a reverse manner.

Claims (4)

  1. Baggerschaufel (B) für eine Erdbaumaschine, wobei die Baggerschaufel mit mindestens einer einstückigen hydraulischen Hammervorrichtung (H) einschließlich eines Meißels (C) ausgestattet ist, die an der Unterseite der Baggerschaufel (B) positioniert und sicher daran befestigt ist, wobei Mittel bereitgestellt sind, um den hydraulische Hammer (H) zu betätigen, wenn die Schneidekante der Baggerschaufel auf ein Hindernis stößt, das auf die Baggerschaufel einen stärkeren Druck als den Druck ausübt, der durch den Betrieb des Motors einer Eradbaumaschine erzeugt wird, an der die Baggerschaufel montiert ist, und wobei möglicherweise weitere Triebwerkseinheiten die entsprechenden Einrichtungen betätigen, dadurch gekennzeichnet, daß die Baggerschaufel ferner mit Mitteln (3,5) ausgestattet ist, die die teilweise Freigabe des Hammers (H) von der Baggerschaufel (B) ermöglichen.
  2. Baggerschaufel gemäß Anspruch 1, wobei die Betätigungsmittel einen Sensor gemeinhin bekannten Typs umfassen, der bei jedem Antreffen eines wie vorstehend erwähnten Hindernisses von Seiten der Baggerschaufel (B) einen Befehl an den hydraulischen Hammer (H) leitet, um den Zertrümmerungsvorgang der hindernden Gesteinsbildung zu beginnen, indem der Hammermeißel (C) direkt eindringt und wobei somit die dem Hammer eigentümliche Leistung in vollem Ausmaß aufgebracht wird.
  3. Baggerschaufel gemäß Anspruch 1 oder 2, worin der Hammer (H) vollkommen von der Baggerschaufel (B) entfernbar ist, um den allgemein bekannten Standardbetrieb getrennt durchzuführen.
  4. Erdbaumaschine, die eine Zugmaschine oder eine ähnliche Antriebsmaschine umfaßt, an der eine Baggerschaufel (B) gemäß einem oder mehreren der vorstehenden Ansprüche schwenkbar angebracht ist.
