  • the auger assembly 32 is mounted on the frame 28, directly in front of the trenching blade 30 relative to the direction of trenching.
  • the auger assembly 32 preferably comprises an auger motor 46, a hub 48, and an auger 50.
  • the auger motor 46 characterized by an output speed, drives a rotation of the auger 50.
  • the output speed of the auger motor 46, and thus the rotation speed of the auger 50 is preferably dynamically varied by operation of one or more of the controls 26.
  • the auger rotation speed can be varied independent of the rotation of the digging chain.36 without affecting the speed of the digging chain as controlled by the trencher motor 44.
  • This aspect of invention provides benefits not found in prior art, for example in varying speed based upon soil conditions.
  • the rotation speed of the auger 50 can be increased, increasing the ability of the auger assembly to move spoils away from the trench.
  • the hub 48 houses bearings and seals and is secured to the frame 28.
  • the auger 50 comprises a threaded length 52.
  • the auger 50 is attached to the hub 48, and rotated by operation of the auger motor 46.
  • the auger assembly 32 is cantilever mounted and level to the ground. More preferably, the auger 50 is placed proximate the digging chain 36 and low to the ground.
  • the auger 50 is attached to the frame 28 at a point between the rear ground drive members 22 and the pivot point 40 of the trenching boom 35. In the embodiment shown in Figure 1, the auger 50 is attached to the frame 28 at a point between the articulation plate 16 and the pivot point 40 of the trenching boom 35.
  • the auger 50 is preferably of a smaller diameter than the traditional trencher auger. A shorter flighting pitch of the smaller auger 50 and increased rotation speed breaks the spoils into finer pieces, allowing the spoils to be conveyed to a side of the work machine 10, resulting in a cleaner trench. Further, this feature makes it easier to return the spoils to the trench.
  • the auger 50 may also be rotated at a higher rate of speed than the digging chain 36, permitting a smaller diameter auger 50. A smaller diameter auger 50 allows for a more compact configuration and increased versatility of placement.
  • the digging chain 36 defines a projected discharge width 54.
  • the flighting, or threaded length 52 of the auger 50 is in front of and traverses across the discharge width 54 of the digging chain 36.
  • This configuration allows spoils to be transferred from one side of the projected discharge width 54 to the other along the threaded length 52 more efficiently.
  • one auger assembly 32 may do the work of a two-auger system. Further, only one pile of spoils is created, reducing the work required in backfilling a trench.
  • the auger 50 may be tilted from horizontal.
  • the auger 50 is inclined relative to the ground.
  • the inclined auger 50 allows the auger flighting to be low to the ground near the digging chain 36, while providing clearance from the ground to an end 56 of the auger remote from the hub 48.
  • the auger 50 orientation may be tilted by adjustment of the hub 48.
  • the adjustment may be made by inclining the auger assembly 32 with shims.
  • the adjustment may be made with a pin-slot arrangement.
  • the adjustment of the auger assembly 32 may be made dynamically using hydraulics.
  • the vertical distance from the auger 50 to the ground may alternatively be adjusted by mounting the auger in a movable frame with incremental adjustments or dynamically with a hydraulic cylinder.
  • the diameter of the auger 50 can be selected to optimize its mounting location and height from the ground.
  • a tilted auger 50 may also be accomplished with a tapered auger.
  • the diameter of the auger or the diameter of the flighting may vary along its length. Further, the auger 50 may be both tilted and tapered.
  • the trenching assembly 14 further comprises an optionally installed backfill blade 58.
  • the backfill blade 58 is mounted to the frame 28 and is preferably located between the auger 50 and the power unit 12. Spoils can be backfilled into an exposed trench without operation of the trenching blade 30 or the auger assembly 32 by pushing the spoils with the backfill blade 58.
  • the backfill blade 58 may be used to guide spoils into the auger assembly 32, for backfilling into the trench.
  • the spoils are deposited near the auger assembly 32. The spoils are then moved from near the digging chain 36 to the end 56 of the auger 50 by rotation of the threaded length 52 of the auger.
  • a pile of spoils forms at the end 56 of the auger 50, instead of in the path of the trenching blade 30.
  • Spoils not removed by the auger assembly 32 are displaced from proximate the newly formed trench by the spoils drag 45, as described earlier.
  • the auger assembly 32 can alternatively be used as a backfill auger. In this configuration, the trencher blade 30 is raised and the trencher motor 44 is not activated. The auger 50 moves collected spoils from the spoils pile to proximate an uncovered trench.
  • the machine 10 is translated in a direction opposite a direction of the trenching operation while the auger 50 is rotated in an opposite direction than it rotates when removing spoil from proximate the trench.

Abstract

L'invention concerne un ensemble d'excavation comportant une nouvelle disposition de tarière. Cette disposition comprend un ensemble tarière et une chaîne excavatrice reliée de manière rotative à un bras d'excavation. Mue par un moteur, la chaîne excavatrice tourne afin de dégager de la terre et de former une tranchée. La terre dégagée ou les déblais s'amoncellent à proximité d'une trajectoire prévisionnelle de la chaîne excavatrice. L'ensemble tarière fonctionne de manière à déplacer les déblais de la trajectoire prévisionnelle de la tranchée. La tarière tourne indépendamment de la chaîne excavatrice et est située de manière à ce que la largeur prévisionnelle de la chaîne excavatrice vienne entrecouper une longueur filetée de l'ensemble tarière. Cette tarière peut tourner plus rapidement que si elle était entraînée par la chaîne excavatrice, ce qui lui permet d'avoir un diamètre plus petit que les tarières classiques. En outre, cette tarière peut être utilisée en conjonction avec une lame de remblayage pour combler des tranchées nettoyées, sans que la chaîne excavatrice ne soit actionnée.
