Definitions

  • This invention pertains to crawler type vehicles and more particularly to an improved cyclic track assembly for same suitable for demolition and compaction of fill materials such as earth, debris, solid wastes, trash, etc.
  • wheeled vehicles having special compacting feet have been used in compacting sanitary land fills, dumps, construction sites, etc.
  • track type tractors using tracks designed solely for tractive purposes have been used for this purpose.
  • Such vehicles have had certain limitations. For example, they have had difficulty in effectively demolishing large rocks, pieces of concrete, etc., as encountered at construction sites.
  • when compacting "wet" materials using the usual track type tractor it has been observed that the materials become impacted behind the track shoes so as to tighten the tracks unduly.
  • wheel-style compactors have a limited ability to break up the stubble prior to discing the stubble into the ground. Since burning of stubble has been prohibited in many areas it must now be disced into the ground.
  • a crawler vehicle equipped with track shoes or pads as disclosed herein readily serves to break up the stubble even more thoroughly than when using only the disc.
  • a crawler vehicle for use in compacting a fill of earth and debris, the vehicle being of a type supported by spaced parallel endless tracks in which the tracks include a plurality of articulated links supporting track shoes, characterized by said shoes each comprising a broad, rigid plate having top and bottom surfaces, a substantial region of the bottom surface acting as a tread surface for engaging the ground, a relief opening formed to extend centrally through said tread surface, said opening being sufficiently large to readily pass fill materials outwardly therethrough to inhibit buildup of impacted materials on the back side of said track shoes, a pair of grouser blades and a pair of aemolition blades carried to protrude generally normal to said tread surface of said track shoes, said demolition and grouser blades being disposed to define escape channels for readily permitting material discharged from said opening to freely leave the track shoe.
  • said pair of grouser blades respectively extend along a substantial portion of the leading and trailing edge margins of said tread surface, said grouser blades being mutually offset laterally to opposite sides of the cen- tedine of the path of movement of the track shoes, and said pair of demolition blades extend diagonally substantially in parallel relation respectively from the leading and trailing edge margins of said tread surface toward said trailing and leading edge margins for demolishing debris, said demolition blades being spaced from said grouser blades to define said channels for passing the material discharged from said opening free of said track.
  • a track shoe for a vehicular crawler track of a type for crushing, breaking, grinding and compacting a fill of earth and debris materials characterized by said shoe comprising a broad, rigid plate having top and bottom surfaces, a substantial region of the bottom surface acting as a tread surface for engaging the ground, a relief opening formed to extend centrally through said tread surface, said opening being sufficiently large to readily release fill materials outwardly therethrough to inhibit buildup of impacted material behind said track shoe, a pair of grouser blades protruding generally normal to said tread surface and respectively extending along a substantial portion of the leading and trailing edge margins of said tread surface, said grouser blades being mutually offset laterally to opposite sides of the centerline of the path of movement of the track shoes, first and second demolition blades protruding generally normal to said tread surface and extending diagonally respectively from the leading and trailing edge margins of said tread surface toward said trailing and leading edge margins, said demolition blades being spaced from said grouser blade
  • a crawler vehicle characterised by some of said shoes having top and bottom surfaces wherein a substantial region of the bottom surfaces serves as a tread surface for engaging the ground, a pair of grouser blades carried by said tread surface extending substantially normal to the path of its associated track, said grouser blades being spaced apart along said path, demolition means carried by and protruding from said tread surface, said demolition means being disposed to substantially continuously support said shoes in the region extending between said grouser blades as the shoe progressively engages the ground to enhance stability of said track.
  • the demolition means includes a pair of demolition blades carried to protrude from said surface and extend diagonally of said path, an end of each of said demolition blades invading the plane of an associated grouser blade, the other end of each of said demolition blades extending substantially through an imaginary plane common to each of said other ends, said imaginary plane being disposed substantially normal to said path and intermediate said pair of grouser blades.
  • An advantage of the invention is to provide an improved compactor vehicle wherein the tread reduces the fill materials (such as concrete blocks, rocks, solid waste, etc.) before it grinds them into the ground.
  • the fill materials such as concrete blocks, rocks, solid waste, etc.
  • Another advantage of the invention is to provide a compactor vehicle having crawler tracks which "run clean,” i.e., remain substantially free of any significant impacted buildup of fill material behind or in the tread.
  • Yet another advantage of the invention is to provide an improved crawler track which enhances stability and smoothness of operation of a compaction vehicle.
  • Track assemblies 11, 12 include a plurality of articulated links 13 coupled in tandem to form an endless or cyclic "belt". Links 13 support track shoes 14 secured thereto by means of bolts 16.
  • Vehicle 10 uses its tracks to demolish and compact a fill of materials such as earth and debris, rocks, refuse, etc.
  • Each shoe 14 comprises substantially a rigid rectangular plate 17.
  • the term "bottom” surface pertains to that surface which acts as a tread surface for engaging the ground as vehicle 10 is moved. It will be readily evident, however, that the "bottom” surface 19, when inverted, (as in Figures 4 and 5) becomes a "top” surface during a substantial portion of its cyclic travel.
  • a relief opening 21 in the form of a relatively large trapezoidal shaped opening extends centrally through shoe
  • Opening 2 1 is sufficiently large to readily release fill material outwardly therethrough so as to inhibit the buildup of compacted materials behind shoe 14.
  • the leading or left-hand edge 19b curves slightly downwardly so as to slide under the trailing edge 19c of a shoe 14 preceding it in track assembly 11.
  • the leading edge margin 24 of plate 17 serves to provide a closure between shoes disposed in tandem along track assembly 11. Accordingly, as the shoes 14 travel a horizontal stretch of their path, edge margin 24 will be disposed beneath trailing edge 19c of a preceding shoe 14.
  • the remainder of the bottom surface of shoe 14 provides a substantial region for engaging the ground referred to herein as the "tread" surface.
  • the region defined within the dimensions x, y comprises the tread surface.
  • a drive sprocket 44 engages link pins 46 to move the track assembly.
  • the sprocket points are aligned to pass directly beneath opening 21 whereby they can assist in urging impacted material out of opening 21.
  • edges 19b and 19c of adjacent shoes move to open and close a gap therebetween. This action as well as that of the drive sprocket 44 causes impacted materials to be urged outwardly through opening 21.
  • a pair of grouser blades 22, 23 carried from the bottom surface of shoe 14 protrude generally normal to the tread surface and respectively extend transversely of shoe 14 along a substantial part of the extent of the leading and trailing transverse edge margins, 26, 27 of tread surface x, y.
  • Grouser blades 22, 23 are mutually offset laterally to opposite sides of the centerline of the path of movement of track shoes 14 for reasons described further below.
  • bottom surface 19 carries a pair of demolition blades 28, 29 which also protrude generally normal to the region of tread surface x, y. Blades 28, 29 extend diagonally substantially in parallel relation respectively from the leading and trailing edge margins 26, 31 toward the trailing and leading edge margins 31 1 26 respectively for purposes of demolishing debris while permitting any impacted material emerging from opening 21 to freely leave the track.
  • Grouser 22 includes a tapered fillet 22a which serves to strengthen plate 17 in the region of the leading edge 21 a of opening 21 and the openings (not shown) for bolts 32.
  • the bolt holes and the elongate edge 21 cause the adjacent portion of plate 17 to be the weakest portion. This weakening of a leading portion of plate 17 has thereby been stiffened by the inclusion of the tapered fillet 22a.
  • Both of blades 22, 23 extend only part way across the full width, y, of shoe 14 and are mutually offset to opposite sides of the centerline of the path of its associated track.
  • Each displacement 33, 34 ( Figure 4) respectively defined between the laterally inner ends of an associated grouser blade 22, 23 and a side edge 36, 37 of the rigid plate includes a gap 38, 39 respectively defined between the laterally inner end of an associated grouser blade and a portion of a demolition blade invading the plane of the grouser blade.
  • Gaps 38, 39 serve to channel debris 42 away from shoe 14. Additional gaps or channels for debris to fall through are indicated at 38' and 39'.
  • Demolition blades 28, 29 lie mainly behind an associated one of gaps 38, 39 in the path of fill materials 42 passing therethrough.
  • Figure 6 represents a track shoe 14 moving upwardly in the direction of arrow 43 as the vehicle moves in a forward direction, i.e., as the track assembly is viewed from behind, impacted debris 42 in back of shoe 14 will be shaken loose by the relative movement between shoes 14 as they move around the end of their cyclic path as well as by the action of the drive sprocket 44.
  • channels 39, 39' permit the loosened debris 42 to pass freely from shoe 14 by gravity.
  • Channels 38, 38' perform this function when the track moves in a reverse direction.
  • the tracks are designed to run "clean" so as to rid themselves of refuse and other fill materials rather quickly.
  • use of the crawler style tracks further enhances this feature inasmuch as the shoes are drawn apart as they pass around the ends of the track. In this manner the tracks further tend to release material.
  • This "track break” between consecutive shoes opens up a slot between shoes giving entrapped debris an opportunity to fall out.
  • the vehicle described above achieves compaction by a substantially different technique than previously.
  • shoe 1 4 includes means protruding therefrom to form a substantially continuous support beneath plate 17 in the region extending between grouser blades 22, 23.
  • shoe 1 4 includes means protruding therefrom to form a substantially continuous support beneath plate 17 in the region extending between grouser blades 22, 23.
  • one end 28a, 29a of each of demolition blades 28, 29 invades the plane defined by an associated one of the two grouser blades 22, 23 respectively.
  • the other end 28b, 29b of each of blades 28, 29 extend substantially beyond an imaginary plane 41 common to each of the ends 28b, 29b, and disposed substantially to the path of an associated one of the tracks 11, 12. Plane 41 lies between the pair of grouser blades 22,23.
  • the smoother ride created by the diagonal segments prevents the machine from rocking and falling from one grouser to the next and enhances the comfort of the operator as well as reducing metal fatigue and machine damage.
  • shoes 1 4 can be employed together with conventional shoes of the type used on track-type tractors.
  • shoe 14 can be al- temated with a standard shoe as desired at the expense of a commensurate loss in function and efficiency.
  • tracks 11, 12 can be driven in opposite directions onto the debris and in this manner virtually “screw" the material into the ground.
