Definitions

  • this invention relates to a street sweeper having new and improved mechanisms for dumping a dirt hopper at a street level position or at an elevated position to permit sweepings to be loaded into a truck standing by or to be stacked in large rather than small piles. Still another important object of this invention is to provide a street sweeper which can also be operated as a front end loader for loading the sweepings directly into a truck.
  • a very important object of this invention is to provide a street sweeper having a front end unloader which has excellent stability during the dumping cycle without requiring any counterbalancing of the load in the dirt hopper.
  • a still further object of this invention is to provide a street sweeper with a front end unloader whereby the dirt hopper can be raised to an elevated position and then moved through an are away from the sweeper so that the sweepings can be dumped as the gravity actuated door is swung open.
  • An important object of this invention is to provide a new and improved dirt hopper handling mechanism which is of compact construction so as to occupy the smallest possible area in order that a larger sized dirt hopper can be used.
  • Another important object of this invention is to provide a new and improved dirt hopper handling mechanism which will not interfere with the operators view and which can be operated to unload a dirt hopper from an elevated position or at ground level.
  • Yet another important object of this invention is to pro- H vide a new and improved street sweeper which is of such construction so as to permit the operator to elevate the dirt hopper from the operators seat so that the operator can then visually determine whether the dirt hopper is fully loaded.
  • the operator wishes-todetermine whether the dirt hopper is fully loaded, it has been necessary for him to step down off the sweeper and open a side door in the dirt box in order to inspect the contents of the hopper.
  • our sweeper is provided with a dirt hopper which can be used as a front end loader by operation of a new and improved dirt hopper handling mechanism. It is now possible with our new sweeper to unload a filled dirt hopper into a truck or on the street in the area being swept so that the sweeper can be continuously used as a sweeper for longer periods.
  • the dirt can be dumped until a truck becomes available at which time the dirt hopper can be utilized as a front end loader to pick up and load the previously dumped sweepings into the truck.
  • the dirt hopper handling mechanism includes a pair of dirt hopper carrying beams on opposite sides of the dirt box and means for elevating the dirt hopper carrying beams and means carried by the beams for rotating the dirt hopper to unload the same.
  • the means for elevating the dirt hopper carrying beam and the means carried by the beam for rotating the dirt hopper are all disposed in a common vertical plane so as to occupy the least possible amount of space in order that the capacity of the dirt hopper may be maintained as large as possible.
  • the dirt hopper is provided with a sweepings inlet that is partially defined by a scoop so that when the dirt hopper is rotated, the dirt hopper can be used as a front end loader.
  • FIGURE 1 is a side elevation of a street sweeper
  • FIGURE 2 is an enlarged fragmentary perspective view of the street sweeper shown in FIGURE 1 withparts broken away to illustrate adirt hopper handling mechanism embodying important features of this invention
  • FIGURE 3 is an enlarged fragmentary View similar to FIGURE 2 only illustrating the manner in which the dirt hopper can be rotated or moved through an arc to unload sweepings; Y 7
  • FIGURE 4 is an enlarged fragmentary view similar to FIGURES 2 and 3 only illustrating the manner in which the dirt hopper handling mechanism may be operated to elevate and then rotate the dirt hopper to unload the sweepings into larger'sized piles;
  • FIGURE 5 is an enlarged fragmentary side elevation of the street sweeper shown in FIGURE 1 illustrating in full and dotted lines the manner in which the dirt hopper handling mechanism can be operated to unload the dirt hopper;
  • FIGURE 6 is an enlarged fragmentary side elevation illustrating in full and dotted lines the manner in which the dirt hopper handling mechanism can be operated to place the dirt hopper in a position so that it can be used as a front end loader;
  • FIGURE 7 is a top plan view of the street sweeper shown in FIGURE 1.
  • a street sweeper 10 is illustrated as having a sweeper body 11 supported on front and rear wheels 12 and 13.
  • One or more side brooms 14 and a main broom 15 are provided for depositing sweepings onto a conveyor 16 (FIGURE 5) so that the sweepings may be deposited into a dirt hopper 17.
  • the controls for operating the sweeper 10, the brooms 14 and 15, the conveyor 16 and the dirt box 17 are operable from an operators seat 18 (FIGURE 7).
  • the dirt hopper 17 has a bottom 19, an upwardly inclined forward wall 20 and an upwardly and rearwardly inclined wall 21 with a hopper door 22 pivotally ioined r v V 3.
  • a hopper scoop 24 lies in the plane of the upwardly and rearwardly inclined wall 21.
  • the scoop 24 further defines a sweepings inlet 25 (FIGURE; 6).
  • the dirt hopper17 iurtherin cludesfa rear wall 26 and side walls 27. When the dirt hopper is in-sweeping. position, the scoop snugly cooperateswith upper sweeper body wall 28m prevent dust from escaping the dirt hopper 17 as it is being loaded'by the conveyor16.
  • the sweeper body l l additionally includes side body portions 30 and 31 which are joined with the upper sweep-' or body wall 28 and extend forwardly ithereof to define a dirt hopper housing 32 (FIGURE '4).
  • a dirt hopper housing 32 (FIGURE '4).
  • a pair ofdirt hopper carrying-hollow side, beams or-arms 33 and 34 are pivotally joined to the side body portions 39 and 31st "pivots"35 and The beams 33; and 34 are joined at oppositeends. with theside walls 27 of the dirthopper .17 at pivots 37 and 38.

  • the rams 41 and'42 are joined with-the beams at pivots 44.
  • Each of the rams andits associatedcbeam aredisposed in a common vertical planeso that-the elevat- ,ing mechanisms may be as co p ct la ibl B a "providing compact elevating mechanisms,theylargest possible dirt hopper 17 may be used on the sweeper machine 10. o c
  • Linkage and means are-also provided to roll over or for rotating the dirt hopper17 on thebeams 33' and 34 to dump the" contents ofthe hopper past the swingingdoor :ZZ thrOugh the dirt box outlet.
  • This linkage and dirt hopper rotating means at each side of the dirt'hopperare also disposed in vertical planes common witlrthe vertical planes of the beams 33 andi34 for compactnessias previously desc ribed.
  • identical linkages-581and 51 are provided on opposite sides of the-dirthopper17. Since the linkages 50 and-51are identical a description of one will suffice for both.
  • the linkage 51 includes a pair of first spaced-parallel links 53 (FIGURE which are-joined at one; end 'at pivots 54 to opposite sides of the associated beam'34.
