Definitions

  • This invention relates to a self-propelled, multi-­part machinery for preparing in situ and spreading out a cold bituminous or cementitious mix.
  • this invention relates to a ma­chinery of the type mentioned above which is provided with all necessary devices for making a road paving by a cold process, including the cleaning of the roadbed which is to be spread as well as screening and crushing devices for the previous paving and weight metering devices for the additives to be employed, so that the whole preparation and spreading out cycle of a bituminous or cementitious mix is made possible.
  • the Applicant suggests the realization of a machinery capable of working by exploiting all ad­vantages that are proper of the cold working and that allows all operations connected with the realization of a complete cycle to be carried out, including the oper­ations of cleaning the roadbed automatically, con­tinuously, on the working site.
  • a self-propelled, multipart machinery for preparing in situ and spreading out a cold bituminous or cemen­titious mix, said machinery comprising means for gather­ing the inert material to be mixed from the roadbed; means for cleaning the roadbed on which the new layer is to be spread, and for exerting a sucking action on such plane; means for transferring the collected material into hopper means which are provided with weighing means for the material itself; means for transferring said material from said hopper means into a screen; means for crushing the material rejected by said screen; a mixer that is fed by said screen and/or by said crushing means; at least a reservoir for the binding material with means for distributing the binding material itself onto the inert material at the point corresponding to said mixer; and a device for spreading the material coming from the mixer itself onto the roadbed previously arranged, according to predetermined values of width and thickness.
  • said means for gathering the inert material to be mixed from the road plane can be made up of conveyor blades and of a cylindrical collect­ing rotor including blade arms, and said means for transferring the material towards hopper means can be made up of a conveyor belt.
  • the hopper means are provided with an extracting-­weighing belt and they unload the inert material onto a vibrating conveyor belt that transfers said material onto said screen, which preferably is of the vibrating type.
  • the mixer is of the type including a double shaft with spraying bars.
  • Two reservoirs for the binding material are preferively provided, the first one of them being at the point corresponding to said means for transferring the material to said hopper means, while the second one is arranged above said mixer.
  • the second reservoir is provided with a pump body for distributing the binding material, the throughput being adjustable and controlled by the weighing device of the hopper means.
  • the device for spreading out the material so pre­pared is preferably made up of a vibratory screed bench.
  • the machinery according to the present invention can also be provided with a general control board for the production cycle as well as with adjusting and control devices.
  • the self-propelled machinery shown in the figure comprises conveyor blades 1 by means of which the material 2 to be mixed is collected.
  • the material 2 is conveyed towards the collection rotor 3 which is provided with blade arms serving the purpose of conveying and lifting the material up to the conveyor belt 4.
  • the reference numeral 5 points out a stockage reser­voir for the binding material.
  • the cleaning and sucking device 6 for cleaning the roadbed 7 on which the new paving is to be spread out is arranged below said reservoir 5.
  • An accumulating hopper 8 comprising the extracting-­weighing belt 9 is arranged at the end of the conveyor belt 4.
  • a vibratory conveyor belt 10 is also pro­vided which conveys the material onto a vibrating screen 11 endowed with a system for selecting the materials according to a previously determined curve.
  • a crushing device 12 serves the purpose of reducing the sizes of the material rejected by the vibratory screen 11.
  • a two-shaft mixer 13 is provided below said vibra­tory screen 11 and below said device 12, said mixer being provided with means for spraying and introducing the binding material coming from the reservoir 5 or from a second reservoir 14 for stocking the binding material, said reservoir being provided with a metering pump for distributing the binding material itself.
  • the reference numeral 15 points out a metering bar which sprays the binding material drawn from the reser­voir 5 or from the reservoir 14 into the space between the old paving plane and the new layer.
  • the machinery according to the invention is also provided with the control board 17 and with wheels 18.
  • the plane to which the new layer is to be applied is simultaneously cleaned and subjected to sucking through the device 6.
  • the material After the material has accumulated in the hopper 8, it is weighed and transferred by means of the conveyor belt 10 to the vibratory screen 11 for undergoing selection on the basis of its granulometry.
  • the material having the required grain sizes is con­veyed directly to the mixer 13, whereas the material whose granulometry is higher than that previously determined is conveyed to the crushing device 12 and then to the mixer 13.
  • Fresh binding material is introduced into the mixer 13 simultaneously with the arrival of said material into the same, the binding material being introduced by means of a double diffusion-device (not shown) which is con­trolled by an adjustable flowrate pump automatically controlled by the weighing device 9.
  • the product is mixed and prepared within said mixer 13 and then it is spread out, after finishing and regenerating, by means of the bench 16, according to values of width and thickness determined on the basis of some specific requirements.
