Definitions

  • the invention relates to earth compacting equipment such as tamping tools. More in particular, the invention concerns a manually guided motor driven working device with a reciprocating working tool.
  • the drive motor which may be an electric motor or an internal combustion motor
  • the drive motor is flanged onto the housing of the working device in a manner that it may be readily exchanged.
  • the transmission of power from the drive motor to the recipro cating working tool is obtained, for example, by a coupling, a crank transmission and an intermediately connected swinging or beating system.
  • an internal combustion engine is used as the drive motor.
  • the drive motor is provided with a suspended cylinder.
  • crank transmission which is built in for the transmission of power between the coupling and the swing or beating system makes the drive motor dependent on a predetermined position of the crank transmission, because the crank shaft of the motor and the transmission shaft that picks up the power are supposed to be in alignment. If that is not the case, the crank transmission must be of large and heavy construction, which in turn results in the disadvantage of increased structural dimensions of the working device. Moreover, such a construction would introduce additional structural difficulties.
  • this problem is solved in that for transmitting the power from the drive motor to the reciprocating tool a tilting or rocking lever is provided, which on the motor side is secured to a connecting rod and converts the rotary movement, for example of the crank shaft of an internal combustion motor, to reciprocating movement, and which at the operating side is secured to a connecting rod which moves the tool by way of a swing or beating system known per se.
  • a further advantage of the embodiment in accordance with the invention is afforded in that the lever arm defined by the connecting rod and the tilting or rocking lever can be changed in size. Applying this to practice means, for example, that in a tamper the stroke of the tamping tool can be adjusted at any time and thus adapted to the existing conditions of'the ground.
  • Such adjusting of the stroke can in accordance with the invention be obtained in a simple manner by manipulation but also automatically by a suitable device.
  • FIG. 1 shows, partly in section, an embodiment of the arrangement in accordance with the invention incorporated in a working device
  • FIG. 2 is a partial view of the arrangement in accordance with the invention.
  • FIG. 3 is a section taken along line A-B in FIG. 2.
  • the drive motor 1 by way of its drive shaft 2 moves a motor connecting rod 3.
  • the motor connecting rod is pivotally connected to the crank transmission of the motor at one end and at the other end it is pivotally connected to a tilting or rocking lever 4 which is journalled for pivotal movement about a fixed point or fulcrum 5.
  • a work side connecting rod 6 is provided which transmits the power from the motor 1 to the tool 8 by way of a swing or hearing system 7.
  • This rod 6 has at its upper end a 3 pivotal connection with the rocking lever 4 and at its other end it is pivotally connected with the upper end of the swing system 7.
  • the motor connecting rod 3 and the motor side of the tilting or rocking lever 4 are provided with additional weights 10.
  • the bore in the tilting or rocking lever 4 for journalling at point 5 is in the form of a slot 11.
  • the displacement of the tilting or rocking lever 4 in the slot 11 may be effected by means of a toothed rack 12 and a toothed gear 13 which engages the rack.
  • the rocking lever is pivotally supported by the shaft 16 of a supporting member 15 in an aperture in the wall of the housing 14.
  • the shaft of the pinion 13 extends from the housing, and a handle may be attached to the shaft 16 of the pinion by means of which the pinion 13 can be rotated in order to move the rocking lever 4 along the fixed point 5 presented by the supporting element 15.
  • the setting or adjusting can be undertaken either manually or automatically when the working device stands still or also during its operation.
