  • This invention relates to a compactor and a method of compaction and, more particularly, to an impact apparatus and a roller compactor for use in pressure, impact and remolding compaction.
  • Earth compaction equipment is usually very large, is self-propelled over the earth being compacted, or is pulled by tractors, or the like.
  • One such piece of equipment is shown in the Le Tourneau U. S. patent 3,183,804, issued May 18, 1965. This type of apparatus provides pressure compacting only. That is, all of the power and weight of the self-propelled compacting machine is used for compacting.
  • a similar piece of equipment is shown by Giertz-Hedstrora U. S. Patent 3,255,682, issued June 14, 1966, which shows a compacting apparatus drawn by a tractor, or the like, wherein the weight of the apparatus and an eccentric fixed on the axle of the compactor creates a vibratory affect which adds vibratory compaction to the pressure compaction.
  • Another form of hydraulic compactor is provided by the Century U. S. Patent 3,909,149, issued September 30, 1975, where a vibratory plate-type compactor is carried at the outer end of the boom of an excavator, or the like, which compactor is vibrated against the earth for compacting same.

  • a work vehicle has a work structure, an impact apparatus supported by said work vehicle and a compactor. Means removably connect the compactor to the work structure and delivers impacting forces from the shank to the compactor.
  • a method for compacting material includes simultaneously impacting said material and controllably applying a steady compressive force on said material and remolding said material with said compactor.
  • compacting apparatus are often used to compact fill placed in a trench following excavators and laying of pipe in the trench. Such trenches are dug commonly by excavators.
  • the compacting apparatus of the present invention can be connected to the excavator to conveniently provide excavation and compaction functions on the one work vehicle.
  • the compacting apparatus provides impact, pressure and remolding types of compaction for efficient working of the material in the trench.

  • the compacting apparatus 10 is comprised of an impact apparatus 17 and a compactor 19.
  • the hydraulic excavator 16 is a conventional-type excavator comprising an undercarriage 18 and a rotatable upper structure 20 that is rotatable about a vertical axis through the undercarriage 18.
  • the upper structure 20 has connected thereto the usual bucket linkage assembly generally comprising the boom 14, the stick 15, and a bucket tilt linkage 22 at the outer end of the stick 15.
  • the linkage 22 is manipulated in a knowamanner by suitable hydraulically-powered jacks or motors 24, 26 and 28, respectively.
  • the bucket 12 is controllably positionable relative to material to be worked, as is known in the excavation art.
  • a mounting rig 30 is provided for connection to the bucket 12 when the bucket is tilted to its most inverted position with the jack 28 retracted and with the cavity of the bucket facing downwardly therefrom.
  • the mounting rig 30 is secured to the bucket 12 and to the bucket linkage 22 so as to be able to move the boom 14, stick 15 and bucket 12.
  • the mounting rig 30 can be readily removed from or attached to the bucket 12 without requiring special tools, hydraulic lift equipment, and the like.
  • the mounting rig 30 supports the impact apparatus 17 at the lower end thereof.
  • the impact apparatus 17 can be an adoption of, for example, a rock breaker.
  • One such rock breaker adopted as an impact apparatus 17 is shown and described in U. S. Patent 3,868,145 in the name of Cobb et al, issued February 25, 1975, and is incorporated herein by reference for a detailed discussion of the structure and operation of the impact apparatus 17.
  • the impact apparatus 17, as shown in Fig. 2 is mounted horizontally on the end of the mounting rig 30 and has a shank 34 pivotally secured at 36 to the housing 38.
  • the shank 34 has an impacting adapter 40 projecting away from the housing 38 and has an impact-receiving portion 42 extending into the housing 38 in alignment with the impacting adapter 40.
  • An impacting member 44 is eccentrically mounted in the housing 38 between flywheels 46, such that when a hydraulic motor in the housing 38 is activated, the eccentrically-mounted impacting member 44 will administer impacting forces to the impact-receiving portion 42 and impacting adapter 40 of the shank 34.
  • the compactor 19, as shown in Figs. 1, 2 and 3, is comprised of a roller portion 50 and a yoke 52 for supporting the roller portion 50.
  • the roller portion 50 includes a plurality of juxtaposed circular discs 54, with each disc having a plurality of radially extending feet 56 with hardened tips 58 thereon.
  • the feet 56 of each disc 54 are spaced axially and circumferentially from the feet 56 of the adjacent disc 54 so as to present a cylindrical member having randomly projecting compacting points or tips 58 projecting from the outer surface thereof.
  • the yoke 52 encompasses the roller portion 50 and is preferably comprised of a rectangularly-shaped frame 60 surrounding the roller portion 50 with the two ends 61,62 of the frame lying parallel to the opposite end discs of the roller portion 50 and with a bridge 64 extending upwardly from the ends 61,62 of the frame 60 and spans across the width of the roller portion 50.
  • the roller portion 50 has an axle 65 extending from the ends thereof into bearings 67 mounted in openings 69 in the vertical legs 71 of the bridge 64.
  • Means, shown as a socket 66, is provided for removably connecting the compactor 19 in a preselected relationship relative to the impact apparatus 17 and delivering impacting forces from the shank 34 to the compactor 19.
  • the compactor 19 is shown connected at the yoke 52 to said impact apparatus which is positioned on or supported by the bucket 12 of the excavator 16.
  • the socket 66 is welded or otherwise secured to the midportion of the bridge 64 for receiving the impacting adapter 40 of the impact apparatus 17.
  • a pin 68 passes through aligned apertures 70 in the ends of the socket 66 and through an aperture 72 in the im pacting adapter 40 for connecting the compactor 19 to the impact apparatus 17.
  • Appropriate hydraulic lines extend from the cab of the excavator 16 to the hydraulic motor in the impact apparatus 17 so that the impact apparatus can be driven to apply positive impacting forces to the impacting adapter 40 and to the compactor 19.
  • the roller portion 50 of the compactor 19 has an axis of rotation 73 and is rotatably connected to the yoke 52 along said axis of rotation 73.

  • a preferred use of the apparatus is for pressure, impact and remolding compaction of a trench.
  • a trench 74 is opened and cleaned, after which the appropriate pipe is laid in the bottom thereof.
  • Back fill is added to the trench 74 over the pipe whereupon the compacting apparatus 10 is lowered into the trench 74 and the impact apparatus 17 is activated to apply impacting forces through the impacting adapter 40 and to the compactor 19.
  • Compressive force or downward pressure is applied through the boom 14 and stick 15 of the excavator 16 to add to the weight of the boom 14, stick 15, bucket 12, impact apparatus 17 and compactor 19.
  • the excavator 16 also simultaneously moves the compactor 19 along the bottom of the trench 74 to compact the soil added to the trench.

Abstract

Un appareil de compactage (10) comprend un dispositif d'impact (17) et un dispositif de compactage (19). Le dispositif d'impact (17), par exemple un concasseur, permet de developper des forces d'impact sur le dispositif de compactage (19). L'appareil de compactage (10) est dispose, par exemple, sur la structure (12, 14, 15) d'un vehicule de travail (16). Le compactage d'un materiau s'avere necessaire par exemple pour assurer le remplissage correct d'une tranchee (74) apres qu'un tuyau ait ete place dans cette tranchee. Le compactage, tel qu'il est effectue par l'appareil de compactage (10), est obtenu par compactage du materiau et application simultanee d'une force de compression sur le materiau et nouveau faconnage de celui-ci. Ainsi, un compactage satisfaisant peut etre obtenu dans la tranchee (74) en utilisant le vehicule de travail (16), vehicule qui peut aussi etre utilise pour creuser et combler la tranchee (74).
