Definitions

  • rock removing process is implemented by one method of breaking the rock using a vibrator or another method of drilling a hole in the rock using a rotary cutter.
  • the method using the vibrator causes serious vibration and noise to happen, thereby incurring the enmity of the people. Accordingly, the latter method using the rotary cutter having a little vibration and noise has the preference.
  • a breaking head has a drilling means and a vertical moving means, and is mounted to an arm of the excavator to form a hole in the rock and remove the rock.
  • the breaking head constructed as described above will obtain the following effects.
  • the rotary pipe is vertically moved by the cylinder operated vertically to implement the excavation work.
  • the breaking head according to the present invention is rotated back and forth by the link operation of the excavator, thereby easily working an inclined surface such as a protruded region.

  • the conventional breaking head constructed and having the working effects as described above has following problems.
  • the breaking head when excavating the inclined surface such as the protruded region of the ground, after the breaking head is rotated at a desired angle back and forth by the link operation of the excavator, the breaking head implements the excavation for the inclined surface, while bearing members installed to a bearing plate (lower plate) of the breaking head are fixed to the ground. At that time, the bearing members are not fixed to the inclined surface of the ground and thus are released from the ground. Therefore, the breaking head is not fixed, and an operator is suffered from the working delay.
  • the breaking head is generally laid on the ground when keeping it. At that time, various operating levers and components mounted to the breaking head may be damaged due to collision against recesses of the ground.
  • an object of the present invention is to solve the problems involved in the prior art, and to provide a breaking head for an excavator, in which a plurality of pivot cylinders for pivoting the breaking head from side to side are installed to rear portions of the breaking head, thereby more smoothly working a side of the ground.
  • Another object of the present invention is to provide a breaking head for an excavator, in which, inclined bearing members having a desired slant angle are attached between bearing members provided along four lower corners of a lower plate, thereby easily securing the breaking head to the ground when excavating an inclined surface or curved surface of the ground.
  • Another object of the present invention is to provide a breaking head for an excavator, in which a pipe is provided to a rear portion of a stationary plate engaged to the pivot cylinder, thereby preventing various components from being damaged.
  • Another object of the present invention is to provide a breaking head for an excavator, in which footboards are provided to a lateral plate of the breaking head, thereby conveniently and safely manipulating various operating levers mounted to the lateral plate.
  • a breaking head for an excavator including lateral plates positioned between an upper plate and a lower plate, and a rotary plate connected to a rotary shaft installed to an upper end of the upper plate, the rotary plate having brackets to be engaged to a link and an arm of the excavator; the breaking head comprising: a plurality of pivot cylinders at a rear portion of the breaking head for pivoting the breaking head left and right around the rotary shaft; and inclined bearing members attached between a plurality of bearing members installed along four corners of the lower plate.

  • the breaking head 100 constructed as described above is mounted to the excavator, and excavates the ground by use of the rotary pipe 22, when implementing the construction work. Operation of this breaking head 100 for excavator is widely known in the art, and the detailed description thereof is omitted therein.
  • the breaking head 100 for excavator further includes a plurality of pivot cylinders 38 at a rear portion of the breaking head for pivoting the breaking head 100 left and right when working a side of the ground.
  • the assembled construction of the pivot cylinder 38 and the breaking head 100 will now be described in detail with reference to Figs. 1 to 3.

  • Inclined bearing members 52 having a desired slant angle are attached between the bearing members 50, as shown in Figs. 1 and 4.
  • the reason why the inclined bearing members 52 are attached to the lower plate 12 is to easily secure the breaking head 100 to the ground when excavating an inclined surface or a curved surface of the ground. Specifically, the inclined bearing members 52 are contacted with the inclined surface of the ground to support the breaking head 100, thereby smoothly implementing the excavating work.

  • the pipe 34 is protruded from the end of the rotary plate 28 by a desired length.
  • the reason why the pipe is protruded from the rotary plate 28 is to prevent various manipulating levers or components attached to the head 100 from being damaged when keeping the head. Specifically, in the case of keeping the breaking head 100 to lay down on the ground, the breaking head 100 is not contacted with the ground but is lifted over the ground by the pipe 34, thereby preventing the components from being damaged.
  • the lateral plate 14 includes footboards 54 attached to both lower end of the lateral plate for supporting feet of an operator, as shown in Fig. 1.
  • the operator can safely manipulate various operating levers (not shown), with the operator standing on the footboards.
