The self-propelled high-performance shot-peening machine combined with a scarifying machine, for the treatment of coatings surfaces of bituminous conglomerate, asphalt, concrete or metal, is composed of a shot-peening unit (A-A), a suction, filtering, separation and storage unit (B-B), a scarifying unit (C-C) and a mechanic-magnetic unit (d-D) coupled together. It comes typically to solve the problem of the removal of the new typologies of “drop” or “lamellar” road markings, with subsequent regeneration of the macro and micro roughness of the road coating, subjecting the surface to be treated to two treatments—integrated milling and shot-peening—by a single pass, adapting itself to the road profile and guaranteeing to remove only the protruding part of the road markings, subsequently immediately regenerating the roughness and microroughness of said surface, noticeably reducing the critical factor of the working time, eliminating the possibility of error in the application of the treatment. The basic principle consists in utilizing the six-drum scarifying machine 20, 20′ only to remove the “protruding” parts without breaking into the road coating, the number of rollers of the drums 21, 22, 23, 24, 25, 26 and the rotation speed being automatically chosen by the programme to optimize results and working speed; same principle applies to the shot-peening, where the rotation speed and the quantity of abrasive can vary, aiming to the highest yield and speed, the whole managed by a system software implemented by an electric device like PLC, Tablet, Smartphone or Wi-Fi Server-Router. It solves also the problem of the recycling of the grit by its overheating with sticking of the bituminous, gummy materials and others, performing their removal by a single pass and their final decontamination from the stuck bituminous materials C′ in a further subsequent sieve 7 with preliminary cooling by intercooler 7′, 7″, the avoid their deformation and ovalization for a correct recycling D, 1″, 1′″ and reuse of the microspheres 1′, 2, 2′. The technology has been applied to a road lorry with three to five axes, with the aim to have a vehicle allowed to free circulation on the roads to reach the possible yards, airports and so on and to be able to work in moving yards without closing the lane or the section where it is necessary to remove the road markings and remake them immediately after. An autonomous self-propelled unit (D-D) with suction, storage and housing of the magnetic group completes the regeneration and cleaning action removing from the surface coating any grit possibly dispersed and not recovered by the shot-peening machine.
High performance self-propelled combined shot-peening machine, for the treatment of coating surfaces of bituminous conglomerate, asphalt, concrete or metal including a shot-peening unit (A-A), a suction, filtering, separation and storage unit (B-B), and a scarifying unit (C-C) coupled together,
Mechanic-magnetic unit collecting metallic materials wherein the magnetic group is composed of three shafts, two idle and one motorized, of a chain or track rotating around said shafts, of a conveyor belt, which interposes between the magnet and the metallic grit to be captured, the material remaining “glued” to the single bar until it reaches the apex of the climb, to detach itself to research a basin collecting said metallic materials, the unit is self-propelled and includes brushes in the front part, dry suction and filtering means and washing means for the collected grit, characterized in that the conveyor belt is a honeycomb conveyor belt provided with Neodymium bars to avoid loss of particles from the belt during conveying them to the collecting basin said Neodymium bars having preferably a size of 20 mm×20 mm×240 mm and being spaced of 50 mm on the honeycomb conveyor belt.
