Definitions

  • the present invention concerns machines for grading road surfaces (see e.g. DE-A-3237718).
  • the aim of the present invention is to provide a machine to lay asphalt, especially on sidewalks or in any case on road sections of limited width, almost fully eliminating the use of manual work but nonetheless providing a finished road surface of extremely commendable characteristics and with a significant reduction in construction costs.
  • the grader according to the invention enters this field with innovative technical solutions that make it unique in its kind.
  • the machine according to the invention comprises a hopper 1 (figure 1) which is connected to the tracked truck 2 by means of a fifth wheel 3 that allows the hopper to rotate about its vertical axis.
  • Levers 4 extend from the tracked truck 2 and support, by means of a so-called parallelogram-like system, the grader blade 5 on which the control post 6 is mounted; the operator that controls the machine climbs onto said control post.
  • the screw feeder 7 is arranged inside the guiding hopper 1 (figure 4) and, by rotating in both directions, moves the material deposited by the hopper in order to make it descend through the outlet 8.
  • the hopper can be loaded by means of a conventional power loader or with a dumper truck.
  • the tow hook 9 allows the machine to be towed with a tractor or a similar towing vehicle.
  • the front wall 10 (figures 5 and 6) of the hopper 1 can swing down completely by virtue of the presence of the jacks 11 that move it, thus facilitating the loading of said hopper by means of a truck of any size.
  • the shape given to the hopper 1 allows the engine and component parts to be accommodated on the side that lies opposite to the opening in the wall 10.
  • grader blade 5 (figures 7 and 8) is connected to the truck that supports the hopper 1 by means of the levers 4, which form a so-called "parallelogram" system.
  • the machine according to the invention allows the asphalt to be laid in various ways depending on the particular requirements.
  • grader blade 5 is mounted on preferably chromium-plated rods 12 arranged in an inclined position with respect to the advancement axis of the machine, thus allowing the material to be distributed uniformly and any obstacles on the roadbed to be passed over more easily.
  • Figure 12 illustrates the laying of asphalt along a strip 13 which is arranged symmetrically along the advancement axis of the machine, and figure 13 illustrates the laying of asphalt on a strip 14 which lies entirely outside the advancement axis of the machine, with the hopper 1 orientated so that its axis is approximately at 45° with respect to the machine advancement axis; figure 14 illustrates the laying of asphalt on a strip 15 which lies partially outside and partially inside the machine, with the hopper 1 orientated at an angle of less than 45° with respect to the axis of the machine.
  • the post 6, together with the associated control panel, remains in a central position with respect to the advancement tracks of the truck that supports the machine.
  • said screw feeders When said screw feeders are present, they are mounted in the rear part of the machine, between the tractor and the grader blade, and this makes it absolutely impossible to discharge the material in a single position, and therefore the material must be first discharged and then conveyed by the screw feeders, which distribute it and leave traces of asphalt even where they are not necessary, thus requiring an additional and expensive road-cleaning operation.
  • the front opening of the side wall 10 allows the hopper 1 to be loaded without entailing losses onto the ground; this is not at all ensured by currently used loading hoppers, which have openings on their side walls to allow this loading.
  • the position of the operator is such that he is ensured of great visibility in any working condition, both onto the loading hopper and onto the strip of ground to be covered with asphalt.
  • said machine allows substantially perfect and uniform laying of the asphalt along the required strip without needing subsequent manual laying operations or cleaning operations, with a significant reduction in the onerous labor costs and a considerable improvement in the laying characteristics of the material.
