Definitions

  • the present invention relates to earth working, loading and transporting machinery and devices. 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.
  • 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.
  • the conventional bucket of each digging and moving equipment is provided with an integral hydraulic hammer device including a conventional chisel, positioned at the bottom of the bucket and securely affixed to it, means being provided to activate the hydraulic hammer whenever the cutting edge of the bucket encounters an obstacle which exerts pressure on the bucket larger than the pressure originating from the action of the engine and possibly other power units actuating the respective equipment.
  • an integral hydraulic hammer device including a conventional chisel, positioned at the bottom of the bucket and securely affixed to it, means being provided to activate the hydraulic hammer whenever the cutting edge of the bucket encounters an obstacle which exerts pressure on the bucket larger than the pressure originating from the action of the engine and possibly other power units actuating the respective equipment.
  • 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 cable CB 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. At the end of its stroke, 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.
