Definitions

  • the present invention relates to a tamping device or soil compactor, and, more specifically, concerns a pole controlled vibrating tamping device with a pole linked to said device through -rubber elastic means.
  • guiding poles such as guiding poles, guiding handles or the like henceforth called guiding poles ⁇ in this specification, by means of which the operator guides the device over the surface to be tamped or compacted.
  • This guiding pole is with some devices of the type involved connected either to a bottom pan subjected to vibrations and pertaining to a plate tamping device or is connected to the machine part designated as applied load which is resilien-tly supported by the bottom trou-gh or pan or by the vibrating rollers.
  • the pole is connected to the device in the above mentioned manner, i.e.
  • the pole is connected to the vibrating tamping device through the intervention of rubber elastic elements.
  • rubber elastic elements serve the purpose of keeping away from the pole the vibrations caused by the movements and accelerations of the vibra-tion generator or the engine driving the same as for instance an internal combustion engine.
  • FIG. 1 is a perspective view of a vibrating soil tamping device according to the present invention.
  • FIG. 2 illustrates on a somewhat larger scale than FIG. 1 a top view of that portion of the device to which the pole is linked.
  • FIG. 3 is a side view of the arrangement shown in FIG. 2.
  • FIG. 4 diagrammatically illustrates in section the connection of the pole to the -tamping device and shows various positions of the pole into which it may be moved along a vertical plane.
  • FIG. 5 diagrammatically illustrates various positions of the pole into which the latter may be moved along a horizontal plane.
  • FIG. 6 is an isometric view of the pole and indicates the location of the center of gravity on the pole.
  • FIG. 7 is a diagrammatic showing of the main parts (masses) of the vibrating soil tamping device.
  • the device illustrated therein is a soil tamper or compactor which comprises a bottom trough 11 adapted to be subjected to vibrations, a vibration generator and an in-ternal combustion engine 12 for driving the vibration generator, said engine 1'2 being mounted on a hood-like cover member 13.
  • the member 13 is supported by springs 30 on the trough 1-1, which is vibrated by the rotating vibratory weight 31 supported on trough 11 at 11a and driven by belt 32 from the engine 12.
  • connection portion 15 for instance by screws 13a (FIG. 3).
  • Connecting portion 15 is provided with two arms or elements 15a and 15b which within the range of their ends are provided with bores 15e, 15d respectively for the passage of screw bolts thereto.
  • Tiltably connected to said elements 15a and 15b is a fork-shaped connecting member 17 of pole 14.
  • this tiltable connection is not by way of a slidable journalling but is effected in a manner which will be described further below.
  • Fork-shaped member 17 is, between the two arms 15m and 15b, provided with an extension 17e (see FIG. 2) and has opposite said extension a socket 17] for receiving the lower end of pole 14.
  • the connection of pole 14 to socket 17j may be effected in any convenient manner for instance by a screw connection.
  • FIGS. 4 and 5 illustrate different possible positions of pole 14 the outer end of which is, provided with handle bars 14b as shown in FIG. 1.
  • the said handle bars are equipped with handle sleeves 26 and are slightly arched away from pole 14.
  • the handle arms and pole have in customary manner adjusting cables, such as Bowden wires and the like connected thereto for controlling the internal combustion engine.
  • adjusting cables such as Bowden wires and the like connected thereto for controlling the internal combustion engine.
  • these actuating cables or the like have been omitted.
  • the guiding fork 17 represents a considerable mass relative to the pole 14 which advantageously is in the form of a pipe, and with d regard to the handle bars 14! which likewise may be tubular.
  • the mass center of the pole including the guiding fork is located within the range of that quarter of the pole length which is located within the range of the link connection. Solely by elastic deformation of the rubber members 18 and 19, it is possible to move the pole about a horizontal geometric axis I into the positions shown in full and in dot-dash lines in FIGS. 4 and 5. Aswill be evident therefrom, a considerable tilting angle a can be obtained.
  • the lowermost illustrated tilting position is limited by engagement of an abutment member 25 mounted on support 15 by a nose 17e of fork-shaped member 17 and engagement of socket 17j by the bottom 15k of a cutout 15jc in support 15.
  • a torque about a horizontal transverse axis is exerted about the vibrating tamper so that the rear portion of the bottom pan 11 will be under a' greater load than the front portion.
  • pole 14 When laterally moving pole 14 about the geometric axis II, pole 14 will, while deforming the rubber members 18 and 19, convey its angular movement to the vibrating soil tamper.
  • the section 15e of connecting portion 15 is provided with a slot 15f through which extends pole 14 while the side walls 15g and 15h of slot 15j spaced from the pole serve as abutments.
  • the abutment member 25 is provided with lateral abutment strips 25a and 25b so that connecting portion 15 is provided with abutments for producing a positive transfer of the angular movement of pole 14 through fork 17 and its elastic coupling connection to the tamping device.
  • Abutments 25a and 15h are engaged by nose 17e and socket 17 f for bringing about a right-hand angular movement of the vibrating soil tamper and limit the elastic angular movement of pole 14 while serving for a positive transfer of the turning moment.
  • a left-hand angular movement of the tamper is effected by engagement of the abutments 2517 and 151g with nose 17e and sockets 171, respectively.
  • the weight of the pole is 25 kilograms.
  • the center of'gravity of thepole is located in that last fourth of the length of the pole which is adjacent the tamping arrangement proper.
  • the length of the pole in this specific example is 130 centimeters, and the distance of the center of gravity of the pole from its connection with the rubber elements is 22 centimeters. The distance of the center of gravity thus amounts to approximately 17% of the total length of the pole.
  • a soil tamping and compacting apparatus having a bottom member adapted to vibrate', a cover member provided With a connecting portion, and means for vibrating said bottom member, said apparatus including pole means for manually handling said apparatus and having a connecting member on the front end adjacent said cover means and handle means on the rear end, at least two elastomeric coupling elements between said connecting member and said connecting portion and connecting said cover means to said pole means so that said pole means is connected to said cover means by a plurality of resilient coupling elements for movement about a transverse axis and universal angular movement about the point of intersection of said transverse axis and the axis of said pole means, said connecting member having an extension on the front end forward of said transverse axis, said connecting portion being provided with an abutment means spaced from and underlying said pole means and a second abutment means on the opposite side of said transverse axis spaced from and overlying said extension, said abutment means being adapted to engage said pole means and extension, respectively, simultaneously upon depression of
  • a soil tamping and compacting apparatus having a bottom plate adapted to vibrate, a cover member provided with a connecting portion and supported on said bottom plate, means to vibrate said bottom'plate and motor means to operate said means to vibrate said bottom plate, said apparatus including pole means arranged for manually handling said apparatus and including a handle portion on the rear end and a connecting member on the frontend adjacent said cover means, said connecting member and connecting portion comprising spaced, opposed, transversely aligned elements, two resilient elements of elastomeric materialV spaced along a transverse axis, each vhaving its opposite transverse ends secured to said opposed elements on said connecting member and connecting portion, respectively, to connect resiliently said cover means and pole means, the axis of said pole means intersecting said transverse axis intermediate said resilient elements so that said pole means has uni- Y versal angular resilient movement about said point of intersection, said connecting member having an extension on the forward end in front of said point of intersection, said connecting portion having rear abutment means rearwardly of said transverse
