Definitions

  • the invention relates to a loading mechanism for a refuse vehicle whereby the rear opening extends substantially vertically between the floor and the sidewalls of the body of the refuse vehicle.
  • a loading mechanism for a rearloading refuse vehicle e.g. for removing household waste.
  • the rear portion of a refuse vehicle shown in Figure 1 comprises the refuse body 1 with rear opening 2 at the top of which the loading mechanism 4 is pivotably fixed in hinge 3.
  • the loading mechanism When the refuse vehicle 1 is being loaded, the loading mechanism rests with its sidewalls 5 against the rear opening 2 and with its underside or floor 6 against the extension plate 7 which at the bottom of the rear opening 2 is attached to the floor 8 of the refuse vehicle.
  • the sidewalls 5 at both sides of the loading mechanism are connected to each other by a partition 9 which at its horizontal underedge joins a crossbeam 10.
  • a hydraulic cylinder-piston pressure combination 11, 12 is mounted as driving means, which preferably extends parallel to the slide member 13.
  • the upperend of the piston rod is connected to the upper end of the slide member.
  • the slide member 13 is able to move up and down and in this process it is guided in suitable elongated slots 15 in both sidewalls 5 by means of the guiding means 16 described further on.
  • the packer blade 17 is pivotably bearing-mounted in a known manner about rod 18. The rotation is also performed by a hydraulic cylinder 19 which has a support 20 in the framework of the slide member and whose piston rod 21 is hingedly attached to an extension piece 22 of the packer blade.
  • the working cycle of the loading mechanism is as follows. We assume that the slide member is in its upper position and the packer blade is in open position 23 (dotted line). The refuse to be loaded is dumped into space 24 on floor 6 of the hopper and the slide member with opened packer blade 23 is slid downwards under the influence of the hydraulic pressure means 11, 12 until the packer blade reaches position 17.
  • the cylinder 19 is now brought into operation and the plate 17 pivots around the rod 18 into its position 25. During this pivoting movement the plate 17 coacts with the floor 6 for compressing the dumped material and shoves it further on towards the rear opening 2.
  • the cylinder 19 keeps its position and the slide member 13 is in coupling 14 again pushed upwards into its upper position 26 by pressure means 11-12.
  • the packer blade so pushes the dumped material further upwards into the rear opening between the slide member wall 28 and the extension plate 7 towards its position 27.
  • this loading mechanism permits the use of but one hydraulic pressure cylinder 11 or a similar driving means for the slide member. This simplifies the hydraulic pressure circuit, lowers the weight and the cost of the loading mechanism, as well as the risk of defect of the hydraulic circuit or the pressure cylinders.
  • the position of cylinder 11 with fixed support 10 at the bottom also raises the pressure efficiency since the cylinder must exert most force exactly when it must push the slide member and the packer blade (traject from positions 25 to 27) carrying the material to be moved upwards.
  • the entire piston surface 29 is used for this upward movement (without reduction of the piston rod cross section).
  • these guiding means 16 preferably comprise friction blocks in combination with roller guides as sliding mechanisms as will be described further on with reference to the detailed drawing in Figure 2.
  • FIG. 1 shows one of the upper corners of the slide member 13 as viewed from the rear side of the refuse vehicle and moving up and down along the inner side 31 of the sidewall 5 of the loading mechanism.
  • the movement of the slide member in slot 15 is guided by guiding means 16 fixed to the upper edge 32 of the slide member.
  • These guiding means 16 essentially comprise a bearing block 33 to whose end, extending in the slot 15, a rectangular friction block 34 is fixed and which comprises a sliding plate 35 e.g. made of bronze.
  • the friction block 34-35 preferably slides against the walls 37 and 30 of the slot 15.
  • a roller guide 36 is bearing mounted on this shaft end and normally rolls against the bottom transverse surface 30 of the slot 15.
  • the bearing block 33 together with this guiding combination 34, 35, 36 is now preferably horizontally movable in the direction from and towards the sidewall 5.
  • This offers the exceptional advantage that in case of frictional wear, particularly on the inner side 37 of the sidewall 5, the resulting play between the guiding means and wall 37 can be reduced. This is important since it is known by experience that increasing play in the slide member guiding slots leads to faster wear therein and on an average also requires more sliding energy. Moreover, chances increase that the guiding means 16 blocks in case of unequal loading on the packer blade across the width of the loading mechanism.
  • the bearing block 33 is fixed to the upper side 32 of the slide member by means of bolt- nut connections 38 thereby using an intermediate clamping plate 39 and through suitable bores 40 in block 33.
  • the bores have a elongated cross section with the greater transverse dimension in the direction perpendicular to the sidewall 5 so that a displacement of the bearing block in that direction becomes possible after that the bolts 38 have been slightly released.
  • the displacement distance can be set by means of the nuts 41 against the stop 42 fixed to the upperside of the slide member.
  • the invention is not limited to the embodiment of the loading mechanism herein described and illustrated.
  • the partition 9 may be con- vexed (dotted line 43 in Figure 1) in the direction of the rear opening of the refuse body in order to stimulate the compressing process in the rear opening.
  • the slot walls 30 and 37 may also be covered with a sliding layer.
  • the roller 36 may also be replaced by a sliding block, for example made of bronze. Cylinder 11 can also be positioned not parallel with the slide member 13.
