Definitions

  • This invention relates to a refuse collector/compactor.
  • the refuse collector/compactor of the invention has been devised principally for use on refuse vehicles of the kind which are used to receive the contents of containers or refuse bins which are lifted and tipped into a collection vehicle.
  • a refuse collector/compactor comprises a body for receiving refuse from containers of refuse, a container lifting and tipping mechanism whereby containers of refuse are lifted and tipped to empty the refuse from the containers, a receiving chamber for receiving the refuse from the containers, and a compactor mechanism for compacting the refuse into the body from the chamber, the compactor mechanism having a compactor member defining a receiving surface at the lower end of the chamber pivotally mounted about an axis transverse to the body to move the member upwards about said axis from a receiving position towards the body and a compacting position, the outer end of the compactor member having an arcuate member extending downwards from said outer end to occupy the lower end of the chamber during movement of the compactor member towards the compacting position.
  • the lifting and tipping mechanism is arranged to lift containers towards an upwardly directed opening into the chamber, the containers being tipped in an elevated position into said opening so that the contents fall towards the compactor mechanism.
  • the lifting and tipping mechanism and the compacting member are mounted on a tailgate assembly at one end of the body, the tailgate assembly being pivotable about an upper pivot to enable discharge of the contents of the body.
  • the body may include an ejector member movable along the body between a receiving position and a discharge position, such movement being towards the tailgate assembly and after the assembly is pivoted about its pivot.
  • the arcuate member may be engageable by sealing means to prevent ingress of refuse during a compacting movement of the compactor member.
  • Retention members may be provided located towards the upper edge of the rear of the body to serve to retain compacted refuse in the body.
  • Drive means for compactor mechanism may be arranged to drive the compactor member in a continuous operative and return movement, in an intermittent operative and return movement, or in timed movement with the operation of the lifting and tipping mechanism.
  • a commercial vehicle chassis/cab 1 has a collector body rigidly mounted on the chassis or demountably attached to the chassis 1.
  • a telescopic piston in cylinder 31 (shown partially extended) pivotally mounted on the body at 33 and pivotally attached to an ejector blade 30 at 32 such that extension of the piston in cylinder 31 drives the blade 30 rearwards on guide rails (not shown) to discharge the contents from the body 2.
  • the collector body 2 has a main rear frame 7. To the rear of this frame an understructure and extension to a floor panel 10 extends rearwards. Semi-triangular side extensions 8 are fitted between the floor extension 10 and the rear frame 7 to provide a chute for the body contents during discharge from the body.
  • a pivot mounting 35 On top of the rear frame 7 is a pivot mounting 35 to which is attached a compaction tailgate assembly 11.
  • the tailgate assembly is narrower than the side extensions 8 and in its travelling and working position, as shown in Fig. 1, sits between the extensions.
  • a receiving hopper 12 At the top of the tailgate is a receiving hopper 12 with an upwardly directed opening into which containers 3 of refuse are emptied by means of a lifter 13.
  • the lifter 13 and its associated mechanism are substantially as described in our British patent specifications Nos. 2191461 and 2232952.
  • piston in cylinder devices 22 perform a dual function, as described below.
  • the compaction assembly 14 consists of an outwardly concave compaction blade 34 carrying at its outer edge an arcuately curved plate 17.
  • the plate 17 extends downwards from said edge to trail behind the blade 34 and follows a radius struck from the axis of pivot 15 and contains an included angle of approximately 45°.
  • a double acting piston in cylinder device 18 pivotally attached to the blade at 19 and to the tailgate frame at 20 such that extension of the piston in cylinder 18 causes the blade 34 to rotate through about 45° from a receiving position A to a compacting position A', and retraction returns the blade to position A.
  • a scraper blade 27 is resiliently mounted to the hopper frame 7 at the lower end of a chute surface 28 and is spring biased against the curved outer surface of the plate 17 of the compaction blade to prevent refuse spill back into the part of the tailgate housing the curved plate 17 in the receiving position of the compaction assembly 14.
  • An interconnecting locking mechanism (not shown) is provided on the tailgate 11.
  • this mechanism locks the tailgate 11 to the understructure adjacent to the rear edge of the understructure.
  • the mechanism releases the tailgate from the understructure and locks a lid 21 of the bin lifter 13 to the tailgate, the lid 21 being shown in its elevated container discharge position.
  • this second mode with the lid 21 locked to the tailgate 11 retraction of the piston in cylinder devices 22 causes the tailgate to rotate and rise about the pivot mounting 35 to the position for discharge of the body contents by operating the piston in cylinder 31, in which position the rear end of the body is opened.
  • a tailgate cross member 36 (see inset drawing in Fig. 1) rows of retention teeth 37 and 38 which have their points directed forwardly to engage the upper part of the body contents.
  • the teeth 37 of one row are located spaced to the rear of and between the teeth 38 of the other row.
  • a tipping mechanism for discharge of the contents of the body may be provided, the mechanism being located at the front of the body 2 which is pivoted to the rear of the chassis and including a ram operating between the chassis and the body.
  • the blade 30 of the kind as shown in Fig. 1 may be pulled along the body by wire bonds interconnected between the ejector blade and the tailgate instead of using the piston in cylinder device shown.
  • Fig. 2 shows a wide lifter and a comparatively large container 3 but it is possible to fit two narrow lifters, each handling smaller containers independently of each other.
  • the collector body and compaction mechanism may be divided down the longitudinal centre line of the vehicle so that the vehicle may be used for the collection of different kinds of material, for example plastics to one side of the division and metal cans to the other.
  • a divided body and two compactors wide containers may be used with a change-over flap in the receiving hopper 12 such that a container of one kind of material may be loaded into one side of the collector body and upon operating the flap a container of metal cans may be loaded into the other side.
  • the system could also be used as a free standing mechanism and, when loaded, collected by a vehicle as above.
  • the compaction mechanism control system may be timed to operate with the lifter system.
  • the mechanism can be independent or may operate continuously accepting loads at random.
