  • the scraping blade is equipped with two counterblades, one fixed and the other hydraulic displacement, for example, depending on the width to be resumed.
  • the mobile scraper blade is intended to come into contact with the ground so as to carry out continuously and automatically, over a large width of the roadway, localized repairs of the latter, that is to say operations of deflagging, to obtain a suitable wearing course, and to avoid the runoff of water on it.
  • the ability to deport the scraper blade allows the repair of curved portions of roads.
  • Such a machine is adapted for road rehabilitation (punctual recovery of a slump of the roadway by the implementation of thin materials), but also to delineate the edges of the road and derast the grasses in the paths and alleys, for example.
  • the first means of displacement of said scraper blade comprise a hydraulic cylinder.
  • the machine comprises a drawbar to a dump truck or a tractor.
  • the second displacement means comprise a hydraulic cylinder and a sliding shaft on which the movable counterblade is able to move.
  • the machine comprises means for adjusting the orientation of the pivoting counter blade.
  • said scraper blade extends, in a first use position, perpendicular to the axis of advance of said machine.

  • the frame 10 carries a drawbar or drawbar 14 to a motor vehicle having a V-shape.
  • the frame 10 is mounted on two wheels 11 and supports a platform 12 for an operator equipped with a control panel 13.
  • the control panel 13 carries several hydraulic control levers of the various operating cylinders which will be discussed later, these joysticks being connected to a hydraulic distributor.
  • the platform 12 has, moreover, railings 18 to secure the use of the machine 1 by an operator.
  • the position (height) of the frame 10 relative to the wheels 11 can be adjusted by mechanical means or hydraulic cylinders.
  • screws 19 for manually adjusting the height of the wheels 11 before the use of the machine 1.
  • the chassis 10 carries on its front part (in this case that intended to be oriented towards the rear of the truck) a scraper blade 15 which is particularly intended for the distribution and leveling of the ground for the filling of holes.
  • the scraper blade 15 consists of a main blade 151, a counterblade 153 which is slidably movable along the main blade 151 and a counterblade 154 which is pivotally mounted at one end of the blade.
  • main blade 151 a counterblade 153 which is slidably movable along the main blade 151 and a counterblade 154 which is pivotally mounted at one end of the blade.
  • the chassis 10 comprises an arm 101 having on its upper part a cleat or heel 102 for maintaining the inclination of the scraper blade 15 (especially when the latter slides) coming to be housed in a complementary shaped groove situated on the face back of the scraper blade 15 ( figure 4 ).
  • the arm 101 has, moreover, a guide jaw 103 on its lower part in which is housed a shaft 104 of complementary shape sliding fixed on the rear face of the main blade 151 ( figure 4 ).
  • the guide jaw 103 of the shaft 104 is equipped with wear shims.
  • the scraper blade 15 is movable laterally, that is to say perpendicular to the axis of advance A of the truck and the machine 1.
  • This displacement of the scraper blade 15 in both directions of the B axis is provided by a hydraulic sliding cylinder 160 integral with the front face of the chassis 10 and the rear face of the scraper blade 15.
  • the scraper blade 15 comprises a counterblade, or cheek, 153 which is slidably movable along the axis B with respect to the main blade 151.
  • the distance between the counter-blade 153 and the counter-blade 154 can thus be adjusted by the operator, the counterblade 153 being hydraulically displaced according to the width to be resumed (the counterblades 153, 154 are so-called recovery blades ).
  • the offset of the counter-blade 153 is between 20 cm and 1 m, for example, preferably between 20 cm and 50 cm, in particular 30 cm.
  • This displacement of the counter-blade 153 is ensured by another hydraulic sliding cylinder 155, which is movable along the axis B, and by a horizontal sliding shaft 157 integral with the main blade 151 on which the counter-blade 153 is able to slide.
  • the counter-blade 154 pivoting is adjustable at an angle of between 35 and 40 °, for example.
  • the articulation means comprise rings in which can be threaded a removable shaft 17 ( figures 1 and 2 ).
  • adjusting bar 158A having a plurality of holes for adjusting the opening angle of the counterblade 154 ( figure 1 ).
  • a rod 158B is disposed between one of the holes of the adjustment bar 158A and a ring 158C located in the upper part of the counterblade 154 so as to maintain the opening angle of the latter.
  • the arm 101 comprises a setting mechanism 101A of the angle of inclination ⁇ of the main blade according to the work to be performed ( figure 4 ).
  • the scraper blade 15 can thus be tilted forwards or backwards.
  • main blade 151 and the counter-blades 153 and 154 have wear blades 151A, 153A and 154A respectively interchangeable.
  • the supply of filling material is through a hopper located at the rear of the truck body.
  • the deformation to be recapped is not disposed in the axis of the truck, it actuates the levers to move laterally the scraper blade 15 relative to the frame 10, and possibly against the blade 153, at the location and to the width of this hole.
  • the filling product is poured into the area to be recapped through the hopper.
  • the distribution and leveling of the product discharged from the hopper takes place as the truck and the machine 1 are towed along the feed axis A, by the scraping effect provided by the lower edge of the hopper.
  • the wear blade 151A which is substantially flush with the ground.
  • the width of the scraper blade 15 being greater than that of the hole being filled, the lower edge of the wear blade 151A therefore bears on the undamaged edges of the roadway.
  • a cylinder allows the compaction of the material in the filled part.
  • the filler material is level with the surrounding surface after settlement.
  • the operator can then intervene on another hole of the roadway.
  • the machine 1 according to the invention makes it possible to treat pavement subsidence locally and over a wide width of the roadway.
  • This machine 1 is both simple to use and powerful in the amount of work provided, and makes the task less painful for operators (the working comfort is improved).
  • the implementation of the machine 1 saves labor by requiring only two operators, instead of a team whose manual labor necessarily slow represents a very low yield compared to the mechanized operation allowed by the machine. the invention.
  • this machine 1 is towed at a speed below 25km / h, for example.
  • this machine 1 For its movement from one site to another, this machine 1 can be raised by the implementation of a lifting system of the machine, including the hooks 156.
  • This machine 1 is thus intended for the rehabilitation of roads but it is also suitable for deligning the edges of the road and deraser grass in paths and alleys, for example.
  • the scraper blade 15 is orientable. It can thus be oriented towards the left side or the right side of the frame 10, and be moved laterally along the axis B.
  • the pivoting of the scraper blade 15 about a vertical axis is ensured for example by a pivot connection (not shown) between the frame 10 and the arm 101 for supporting the scraper blade 15.
  • the inclined blade collects and deflects / repels the residues (earth, grasses, chippings, ...) to the side when the machine 1 towed moves in the direction of advance A.
  • the orientation angle of the scraping blade 15 is between 10 and 60 ° for example, preferably between 20 and 40 °.
  • the machine 1 may be equipped with a scraper blade 15 non-steerable.
  • the invention thus makes it possible to provide professionals, maintenance companies, public works companies, as well as road and community equipment services with a tool that can be used to maintain and even renovate punctually degraded roads.
  • the drawbar can be adjustable in height.
