Definitions

  • This invention concerns generally compaction machinery such as a roller for mounting upon a driven compaction vehicle, the roller having both destructive and tractive characteristics adapted to break up, crush, grind and compact materials of the size of home appliances as encountered in sanitary land fill operations.
  • Compaction rollers and wheels used on land fill operations and particularly sanitary land fill operations are equipped generally with cleats or feet of a type for grinding and crushing the material beneath it so as to reduce the material in size for compaction.
  • cleats or feet of a type for grinding and crushing the material beneath it so as to reduce the material in size for compaction.
  • an earth and sanitary fill compaction roller has been shown employing two different types of feet having replaceable wear caps as part of its cleat assemblies. The wear caps are welded to a base portion of the assembly which in turn is welded to the roller.
  • a fill and compaction roller of a type having a rigid cylindrical body supported for rotation from a vehicle chassis and having cleat assemblies carried by the body, the cleat assemblies each comprising a rigid mounting pad assembly having a base portion attached to said body and a cap unit releasably attached to the base portion by a coupling pin, each cleat assembly including a bracket integral to said base portion protruding radially outwardly therefrom and having a coupling opening extending transversely through the bracket, and wherein the cap unit comprises a generally hollow body including sloping upwardly converging outer side walls and transverse end walls extending between the end edges of said side walls, a pair of aligned openings respectively being formed through the side walls and aligned with said coupling opening for receiving the coupling pin therethrough, which coupling pin being disposed through said coupling opening and said aligned openings to retain said cap unit to said mounting pad assembly, and there being further provided annular recesses surrounding each end of
  • a fill and compaction roller is characterised by further including means serving to closely guide said cap unit on to said bracket including a pair of confronting substantially parallel abutments extending radially outwardly along the inner surface of the confronting sloping walls of the hollow body of said cap unit, said aligned openings being disposed to extend through said abutments, said bracket having a pair of transverse flanges flanking each end of said coupling opening to form a guide slot at opposite ends of the opening for receiving an associated one of said abutments slidable therein, said abutments being closely spaced to said locking means to capture and retain said locking means in their associated recesses.
  • each said locking means comprises a split ring disposed within each said recess.
  • An advantage of such an arrangement is that a compaction roller has been provided wherein the wear cap can be readily removed using common tools available at the job site. In this way replacement of the wear caps before the supporting base becomes worn to a point requiring its removal has been encouraged.
  • the rigid mounting pad assembly has a base portion adapted to be welded to the body.
  • An advantage of the invention is to provide a cleat assembly of a type requiring minimal time and labor to replace using ordinary tools.
  • the roller assembly 10 is represented diagrammatically and can be constructed according to U.S. Patent No. 3,724,342 assigned to Caron Compactor Company to incorporate cushioning elements, cleaning members, and the like.
  • Roller 10 has been mounted upon a perimeter frame 14 of vehicle 13.
  • Frame 14 is of a type including cross members 16,17 extending across the tread of the roller 10.
  • Cleat assemblies 18, 19 as described more fully below are arranged on the outer surface of the cylindrical rim 11. Cleat assemblies 18 primarily serve to provide traction while the primary function of assemblies 19 is to crush materials.
  • cleat assembly 18 includes a rigid mounting pad unit 21 having a base portion 22 curved along edge 21a to conform to the curvature of rim 11 so as to be adapted to be welded to the rigid body formed by rim 11.
  • a bracket 23 formed integral with base portion 22 protrudes generally radially outwardly therefrom.
  • a coupling opening 24 extends trnasversely of bracket 23 and enlarged annular recesses 26 surround each end of opening 24.
  • wear cap unit 29 is adapted to be readily releasably coupled to base portion 22.
  • Wear cap unit 29 has a generally hollow body including sloping upwardly converging outer side walls 29a and transverse end walls 29b extending between the end edges of side walls 29a.
  • a pair of aligned openings 31 extend through side walls 29a in position to be aligned with coupling opening 24 of bracket 23. In this way coupling pin 28 can be readily disposed to extend through openings 31 and 24 to couple wear cap unit 29 to its mounting pad unit 21.
  • Means for readily releasably locking pin 28 in openings 31, 24 serves to prevent decoupling of cap unit 29 from pad assembly 21 as now to be described.
  • a hammer can be used to drive a screw driver against an end of pin 28 to move it through cap unit 29 until pin 28 is released from split rings 27.
  • cap unit 29 means have been provided serving to closely guide cap unit 29 onto bracket 23. Accordingly a pair of confronting substantially parallel abutments 32, 33 extend radially outwardly along the inner surface of the confronting sloping walls 29a of the hollow body of cap unit 29.
  • openings 31 extend through these abutments in alignment with coupling opening 24 of bracket 23.
  • the confronting faces 23a, 23b of a pair of transverse flanges flank each end of coupling opening 24 to form a guide slot at opposite ends of opening 24 for receiving an associated one of abutments 32, 33.
  • Bracket 23 includes a registration surface or face 23c extending between the confronting faces 23a, 23b.
  • cap unit 29 has been disposed onto bracket 23 as represented by the phantom lines 34 in Figure 3 the opposed faces of abutments 32, 33 will be disposed in closely spaced relation to the registration surfaces 23c of bracket 23 so as to fully capture split rings 27 in their respective recesses 26.
  • bracket 23 includes a pair of "slots" on opposite sides of the bracket for receiving abutments 32, 33.
  • the "slots" are defined by the wall faces 23a, 23b and 23c. Accordingly, these guide “slots" serve to receive an associated one of the abutments closely spaced therein.
  • a cleat assembly 19 primarily used for crushing, breaking and grinding of materials of the size of home appliances as encountered in sanitary land fill operations includes a rigid mounting pad unit 37 including a rigid metallic base portion 38.
  • Base portion 38 supports an elongate relatively thin aligning guide 39 formed integrally with base portion 38.
  • Aligning guide 39 includes an upwardly extending bracket portion 41 characterized by an upwardly protruding key 42 disposed within a downwardly opening pocket 43 defined within a removable wear cap 44.
  • aligning guide 39 serves to provide three spaced' points of support as now to be described.
  • the hollow interior 46 of cap 44 slopes downwardly and-away to form a notch 47, 48 for receiving the tip ends 49, 51 of guide 39. Accordingly, as thus mounted, by lodging the tips 49, 51 in notches 47,48 wear cap 44 is restrained against being twisted relatively to base portion 38 about an axis normal thereto, such as axis 52.
  • key 42 engaged in pocket 43 serves to restrain wear cap 44 from being twisted laterally with respect to base portion 38, for example, as about the axis 53 parallel to base portion 38.
  • a coupling pin 54 extends through an opening disposed transversely of bracket portion 41 as described above with regard to bracket 23.
  • Each end of the coupling opening 56 is similarly surrounded by an annular recess 57.
  • Coupling pin 54 accordingly retains wear cap 44 to mounting pad assembly 37.
  • base portion 38 is arcuately formed to conform to the peripheral surface of rim 11 and adapted to be welded thereto.
