Definitions

  • a soil-engaging, supporting foot for an excavating machine or other heavy construction machine consists essentially of a plate, a hinge on the plate for attaching the plate to the machine in a normally horizontal position, a skirt depending from the plate and having a lower cutting edge extending in a closed path, and spikes downwardly projecting from the skirt.
  • the upper edge of the skirt and the circumference of the plate define openings in the plane of the plate.
  • Narrow wedges or similar spikes project from the face of the known foot into the ground to prevent horizontal shifting movement of the foot under the normal operating stresses.
  • The. known supporting elements perform their intended functions satisfactorily when used in the same place for extended periods. The are less sufficient when the supported machine must be moved frequently during its operation, as is I normally necessary with excavating machines. The feet must be lifted from the ground before the machine can be moved to a new location on its own wheels or on a transporting carriage. If the soil is wet, as is frequently the case, clods of compacted soil stick to the plate and to the spikes and prevent proper anchoring of the foot at the new location unless removed in an operation which is time consuming and reduces the operating efficiency of the machine and of its crew.
  • An important object of the invention is the provision of a soil-engaging foot for a construction machine of the type described which automatically cleans itself of adhering soil carried over from a previous location when put in position at a new location.
  • Another object is the provision of better vertical and lateral anchorage for construction machinery by means of an improved supporting foot which is not significantly more complex nor costlier than a conventional soil-engaging foot of similar weight and bulk.
  • the invention provides a soil-engaging support element having a plate number normally attached to a construction machine in a horizontal position with a skirt of rigid sheet material fixedly fastened to the plate member and depending from the same.
  • the skirt has at its bottom an exposed, narrow cutting edge which extends in a closed path. Spikes which are spaced from each other along that path are attached to the skirt and project downwardly from the same.
  • the illustrated foot has a heavy, normally horizontally extending steel plate 1 from which a skirt 2 of similar rigid sheet or plate material depends at right angles.
  • the plate 1 is square in the plan view of FIG. 2, and the skirt 2 forms the outline of a four-pronged star or of a square whose sides were deformed to shift the center of each side slightly toward the center of the square.
  • the centers of the two squares or approximate squares coincide, but the squares are angularly offset about the common center in such a manner that the diagonals of each square bisect the angle between the diagonals of the other square.
  • the two squares have sides of equal length, and the aforedescn'bed angular orientation causes triangular apertures to be defined at each corner of the skirt Zbetween the sides of the plate 1 and the top edge of he skirt in theplane of the plate.
  • the center portions of each side of the skirt 2 are covered by the corners of the plate 1, but the covered skirt portion amounts to less than onedtalf, actually less than onethird of the circumference of the skirt, and is merely long enough to permit the skirt to be firmly fastened to the plate 1 by spot welds.
  • the top of the plate 1 carries two apertured hinge plates 5 which normally receive therebetween a corresponding plate (not shown) fixed on a leg of the excavator, and fastened to the plates 5 by a nonillustrated horizontal pivot pin.
  • the skirt 2 is assembled by welding from four identical sections which are V-shaped in plan view, and whose bottom edges 3 slant obliquely upward from the apex of the V.
  • the skirt is thus saw-toothed and its narrow lower edge varies in its spacing from the plane of the plate 1, being nearest the plate at the comers of the latter.
  • Spikes 4 are welded to the skirt 2 in its four corners respectively and project downwardly beyond the edges 3.
  • FIG. 1 shows a soil-engaging support element of the. invention in front elevation
  • FIG. 2 illustrates the apparatus of F IG. 1 in plan view
  • FIGS. 3 to 5 are respective diagrammatic plan views of modifications of the apparatus of FIGS. 1 and 2.
  • FIGS. 1 and 2 there is seen one of the four soil-engaging feet of a self-propelled excavating machine, such as a bucket excavator which normally travels on wheels or caterpillar tracks, but is equipped with legs lowered to support the weight of the machine and operating stresses when the machine is at a working location.
  • a self-propelled excavating machine such as a bucket excavator which normally travels on wheels or caterpillar tracks, but is equipped with legs lowered to support the weight of the machine and operating stresses when the machine is at a working location.
  • Each leg is equipped machine, it carries with it adhering soil, but this material cannot interfere with proper anchoring of the element at the next operating location.
  • the adhering clods of soil are discharged upward through the apertures along the upper edge of the skirt 2.
  • the comers of the plate 1 do not significantly interfere with this self-cleaning operation.
  • the sawtooth shape of the skirt facilitates penetration of the soil and the striping of adhering soil clods from the skirt
  • the modified support element seen in FIG. 3 has a square horizontal plate 1' whose diagonal is approximately equal to the side of the square formed by the skirt 2.
  • the circumferential length of the skirt 2' covered by the plate 1' is thus reduced to a minimum in this arrangement, but reinforcing elements, not shown, must be provided at the corners of the plate 1' for the necessary rigid connection of the plate to the skirt 2.
  • FIG. 4 thus shows a square plate 1" associated with a circular skirt 2", the square of the plate being inscribed in the circle of the skirt.
  • the rectangular plate 1" in FIG. 5 is mounted within an elliptic skirt 2". Other modifications in the shapes of the plate and skirt will readily suggest themselves.
  • a soil-engaging support element for a construction machine comprising, in combination:
  • hinge means for hingedly fastening said member to said machine in a horizontally extending plane in the normal operating condition of said element
  • said spikes being spaced from each other along said path and projecting from said edge in a normally downward direction.
  • hinge means include a pivot having an axis substantially parallel to said plane.
