Definitions

  • the present invention concerns an excavator bucket and crusher for a loader or excavator and of the kind specified in the preamble of claim 1.
  • Prior art excavator buckets and crushers are very large and complicated tools requiring very large and space-consuming loaders or excavators which additionally are very expensive in acquisition and service.
  • the excavator bucket and crusher is characterised in that the movable part of the crushing mechanism includes gripping means arranged to grip and clamp an object which is to be picked up for crushing by means of the crushing mechanism, and that the stationary part of the crushing mechanism is constituted by a grating-shaped wall section of the excavator bucket and crusher.
  • the excavator bucket and crusher according to the invention may be suitably designed so that the stationary part of the crushing mechanism is designed with rows of tooth-like projections, and that the movable part of the crushing mechanism is also designed with rows of tooth-like projections arranged to engage the tooth-like projections of the stationary part of the crushing mechanism, as respective tooth-like projections of respective parts of the crushing mechanism are mutually complementary in position, i.e. engaging between and with each other.
  • the excavator bucket and crusher according to the invention may advantageously be further designed so that the tooth-like projections on the stationary, grate-shaped open wall section of the excavator bucket are narrow and mutually spaced apart so that the tooth-like projections of the movable part of the crushing mechanism may be inserted between the narrow projections of the stationary grate-shaped wall section of the excavator bucket and crusher.
  • the excavator bucket and crusher according to the invention may be designed so that the tooth-like narrow projections of the stationary part of the excavator bucket and crusher are designed with transverse grooves.
  • the excavator bucket and crusher according to the invention may be designed so that the said stationary part of the crusher mechanism is constituted by a plate-shaped wall section of the excavator bucket, the wall section including a convex, curving, plate-shaped reinforcement which is designed with rows of tooth-like projections that positionally are complementary to rows of tooth-like projections of the movable part of the crushing mechanism.
  • the excavator bucket and crusher is closed downwards by means of a plate-shaped wall section constituting the stationary part of the crushing mechanism, so that it becomes easier to control the discharge of crushed material from the crushing mechanism.
  • the discharge of crushed material may hereby e.g. be loaded more easily into a container constituting a temporary depot, as the crushed material - as mentioned in the introduction - according to official requirements is to be recycled to the greatest possible extent at the demolition site as filler material at the construction of new buildings replacing demolished buildings.
  • the excavator bucket and crusher according to the invention is suitably designed so that the crushing mechanism is drivingly connected with or includes two hydraulic cylinders which are disposed with mutually spacing at each their side of the excavator bucket and crusher.
  • this may suitably designed with a socket part adapted to interact with a fast-action coupling disposed at the said extreme end of the excavator arm.
  • the excavator bucket and crusher according to the invention may advantageously be designed so as to include a vibrator mechanism mounted either at the stationary part or the movable part of the crushing mechanism.
  • the excavator bucket and crusher according to the invention may in an optimal way be designed so that vibrator mechanism is constituted by a hydraulic vibrator which is effectively connected with the movable part of the crushing mechanism.
  • FIG. 1 An embodiment of a combined excavator bucket and crusher 2 is shown in Fig. 1 , where the excavator bucket and crusher 2 is mounted by means of a fast-action coupling 4 at the extreme end 6 of an articulated excavator arm 8 of an medium-sized excavator 10.
  • the excavator bucket and crusher 2 cf. Fig. 1 , is shown separately in Figs. 2-4 , in which it clearly appears that the excavator bucket and crusher 2 is predominantly designed as a common medium-sized excavator bucket where a stationary part 11 of a crushing mechanism 12 is constituted by a grate-shaped wall 14 of the excavator bucket and crusher 2 which is provided with standard digging teeth 16 and connecting parts 18, 20 adapted for connecting the excavator bucket and crusher 2 with the fast-action coupling 4 so that the excavator bucket and crusher 2 may be rapidly substituted by another tool.
  • the crushing mechanism 12 is driven by two hydraulic cylinders 22 and includes a movable part 24 which by means of plate-shaped pivoting arms 26 are pivotably suspended about a transverse axis of pivot 28 arranged between sidewalls 30 of the excavator bucket and crusher 2.
  • the movable part 24 is provided along a free outer edge 32 with projecting gripping means 34 intended for use in picking up objects to be crushed by means of the excavator bucket and crusher 2, as such a crushing object is jammed between the stationary part 11, i.e. the grate-shaped wall 14 and the gripping means 34, before the excavator bucket and crusher 2 is pivoted upwards to a position where its opening is predominantly facing upwards, so that the crushing object is brought in place between respective active parts of the crushing mechanism 12, after which the latter is activated by means of the hydraulic cylinders 22 so that crushing object or objects are crushed before discharge from the excavator bucket and crusher 2 through the grate-shaped wall 14. It may be necessary to activate the crushing mechanism several times until the crushing object has been comminuted so much that all parts thereof can pass out through the grate-shaped wall 14.
  • movable part 24 is provided with rows of tooth-like projections 36 which by disposition are complementary to projections 38 on single plate slats 40 of the grate-shaped wall 14.
  • the grate-shaped wall 14 of the excavator bucket and crusher 2 includes strong transverse rods 42 that run through the slats 40 and which are connected with these and with the sidewalls 30 of the bucket.
  • the projections 38 on the slats 40 are disposed opposite the tooth-like projections 36 of the movable part 24 so that these positionally complementary parts contribute to make efficient the crushing action of the excavator bucket and crusher 2.
  • the excavator bucket and crusher 2 may advantageously - as shown with punctuated lines in Fig. 4 - be provided with a preferably hydraulic vibrating mechanism 58 which has been fitted upon the bucket between the hydraulic cylinders 22, and which via an actuator arm 60 is effectively connected with the movable part 24 of the crushing mechanism 12.
  • a hydraulic vibration mechanism may be placed inside the excavator bucket and crusher 2 directly on top of the movable part 24 of the crushing mechanism 12.
  • Fig. 5 an alternative embodiment of a excavator bucket and crusher 44 which instead of the grate-shaped wall 14 is provided with a closed plate-shaped wall 46 which opposite tooth-like projections 48 of a movable part 50 is provided with a convex, curving reinforcement plate 52 provided with tooth-like projections 54 which positionally are complementary to the projections 48, i.e. may interact with these with the intention of making efficient the crushing action of the excavator bucket and crusher 44.
  • the movable part 50 is provided with gripping means 56 which are intended for use in collecting crushing objects which thereby may be clamped between the gripping means 56 and the stationary part in the form of the closed plate-shaped wall 46.
  • gripping means 56 which are intended for use in collecting crushing objects which thereby may be clamped between the gripping means 56 and the stationary part in the form of the closed plate-shaped wall 46.
  • identical parts of the excavator bucket and crushers 2 and 44, respectively, are provided with identical reference terms.
