Definitions

  • the invention relates to a mobile device for cold production and spreading on site of bituminous coated products for road surfaces.
  • Road surfaces made from bituminous materials are generally obtained by spreading aggregates coated with bitumen on the surface to be coated followed by compaction of these coated materials.
  • the aggregates are made up of pebbles of varying sizes and are generally mixed with a certain proportion of pulverulent materials.
  • the processes for hot preparation of coated materials require complex installations which ensure both the drying and heating of the aggregates, the incorporation of the pulverulent into these aggregates and the coating of the mixture with molten bitumen.
  • Such facilities can be installed ! tees permanently on an industrial site or on the contrary on an occasional site for the duration of a road construction site.
  • bituminous emulsion, water and additives are incorporated into the aggregates with powdered materials, making it possible to improve the adhesiveness of the bitumen on the aggregates before producing the most homogeneous mixture. possible of the whole in a mixer.
  • Such machines include a chassis mounted on wheels carrying all of the storage capacities of the various materials necessary for the manufacture of the mixes, various means of sampling and metering of these materials, means for transferring the materials to the mixer, the mixer itself making it possible to pour the coated products continuously onto the ground and possibly a means allowing the coating to be finished.
  • Machines have also been proposed which can move on the road and which include part of the components necessary for the manufacture of cold mixes mounted on a truck or a trailer. Such devices do not include means for self-feeding of aggregates and require. supply by an additional construction machine. These machines are therefore not autonomous and their supply is discontinuous. We lose the benefits of their mobility on the road.
  • All known self-powered devices include a motor whose kinematics does not allow the machine to operate according to the needs of the operation, in transfer or in spreading. These machines have a motorization calculated only for the implementation of asphalt, at low speed. Their speed of movement is limited by construction to 15/25 km per hour.
  • Coating machines are also known truck comprising an aggregate storage hopper which can be supplied with aggregates from a receiving hopper located at the bottom of the machine, by a bucket elevator bringing the aggregates to the upper part of the storage hopper .
  • Such a machine which is described for example in patent GB-A 396,625 has the advantage of having means for supplying the aggregate storage hopper whose size is reduced in the longitudinal direction.
  • these means do not allow a replenishment of the storage hopper during the operation of the device for preparing the road surface.
  • the hopper is filled from the rear of the machine during a stop of the latter and the operation of this machine is therefore essentially discontinuous.
  • Such a machine is also not designed to be able to move on the road at high speed and its storage hopper (in two parts in the device of patent GB-A 396,625) nor the means of replenishing this hopper are not designed to obtain a maximum hopper capacity taking into account the dimensions of this machine.
  • the object of the invention is therefore to propose a mobile device for the cold preparation and spreading on the site of bituminous coated products for floor coverings during the movement at slow speed of the device which is also capable of moving on high-speed road and which comprises a chassis mounted on wheels carrying a large-capacity aggregate storage hopper associated with feeding means comprising a receiving hopper disposed at the front and at the bottom of the device and a lifting buckets for transporting aggregates between the receiving hopper and the upper part of the storage hopper, storage capacities for powdery materials, bituminous emulsion, water and additives and means for withdrawing these materials from their storage capacity in metered quantities and supply of these materials to a mixer also carried by the chassis ensuring the continuous discharge of the products onto the ground , a device which is entirely autonomous on site and which is fitted with a storage hopper for. high capacity aggregates and means for feeding this storage hopper during operation of the device, while remaining at road standards without structural modification, for its transfer by road from one site to another by its own means comprising a single engine.
  • Figure 1 is an elevational view in partial section of the mobile device according to the invention.
  • FIG. 2 is a view along F l of FIG. 1.
  • Figure 3 is a section along AA of Figure 1.
  • FIG. 4 is a view along F 2 of FIG. 1.

  • the device comprises a chassis 1 resting on four sets of wheels 2a, 2b, 2c, 2d, the axles of the trains 2c and 2d being powered by the bridges 3 and 3a.
  • a power unit comprising in particular a heat engine 5 and a gearbox 6 makes it possible to move the machine both on the road and on site. This motorization group will be described in detail with reference to FIG. 5.
  • the chassis 1 carries a machine operator's cabin 10 whose width is less than the half-width of the chassis and which occupies only part of the left half of this chassis. A part of the right half of the chassis is occupied by a storage capacity for additives 11 in liquid form with a capacity of 2000 liters.
  • This self-feeding device comprises a receiving hopper 14 placed at the front of the machine and at its lower part just above the ground 7.
  • This hopper 14 is placed transversely and has a width slightly greater than the width of the chassis, its lateral parts being foldable during road movements of the machine.
  • the hopper 14 comprises a material refocusing screw 16 comprising two parts with opposite pitches. This screw 16 makes it possible to direct the materials introduced into the hopper 14 towards the outlet of the latter communicating with the inlet of the casing 17 of the bucket elevator 12.
  • the receiving hopper 14 is fixed to the end of the side members of the chassis 1 and the bucket elevator 12 communicating with the central part of this hopper is arranged between the two side members at the central part of the device.
  • the bucket elevator 12 comprises a casing 17 and a set of buckets carried by two chains 18 whose direction of upward movement towards the rear of the machine makes an angle of 60 ° with the plane of the chassis 1.
  • the upper part of the casing 17 of the bucket elevator 12 communicates through its outlet opening 19 with the upper part of the hopper 20 for storing aggregates.
  • this hopper 20 occupies most of the length of the machine and its width, at least in its upper part, is little less than the total width of the chassis. Above this hopper and over its entire length is placed an aggregate distribution device called a strip leveler making it possible to spread the aggregates over the entire length and over the entire width of the storage hopper 20.
  • the bar leveler 31 is constituted by one or two endless chains 21 wound on pulleys or end sprockets 22 and carrying transverse bars 23 whose spacing is identical to the spacing of the elevator buckets and whose course is very slightly tilted upwards back and forth.
  • the pulleys or pinions 22, as can be seen in FIG. 3, are mounted two by two on axes 24 mounted journalled in bearings 25 integral with the vertical walls of the hopper 20.
  • the bucket elevator 12 and the leveler bars 31 are driven in their movement allowing the transport of aggregates 27 by a hydraulic motor associated with reducers which have not been shown.
  • the displacements of the bucket elevator and the bar adjuster 31 will therefore be in perfect synchronism.
  • the buckets and the bars are always in the same position relative to the upper part of the storage hopper 20 where the aggregates are discharged by the buckets into the hopper.
  • the bucket 28 of a truck enabling the aggregates to be supplied to the machine has been shown in dashed lines in its position for dumping into the receiving hopper 14.
  • the chassis of the truck is then connected by a device hooking 29 to the machine and the rear door of the bucket is connected to a pivoting hook 30.
  • the aggregates 27 are discharged in a perfectly controlled manner into the receiving hopper 14 and then transported by the bucket chain 18 to the upper part of the hopper 20 where the bar leveler 31 allows the spreading of the aggregate load over the entire surface of the hopper 20 of large section by transfer to the rear of the aggregates.
  • the synchronism between the bucket elevator 12 and the bar leveler 31 is ensured so that the buckets pour the aggregates between two successive bars 23.
  • a storage hopper 20 For a chassis width of 2.50 meters, a total height of the machine of 4 meters and a length of 11 meters, one can have a storage hopper 20 with a capacity of 10 cubic meters.
  • a belt conveyor 34 carrying out the extraction and the volumetric metering of the aggregates from the hopper 20 which are driven by the conveyor 34 up to the inlet opening of the mixer 35 into which fall the aggregates brought by the conveyor 34.
  • the drive rollers of the conveyor 34 are rotated by a hydraulic motor which has not been shown.
  • the mixer 35 In the opening of the mixer 35 also pours in metered quantities the pulverulent contained in a storage hopper 36.
  • the hopper 36 At its lower part the hopper 36 comprises a recentering screw 37 then a skimmer-metering device 38 allowing the pouring in metered quantities of the pulverulent (which here is cement) in the mixer 35, at the same time as the aggregates 27.
  • the lock and metering device 38 is rotated by a hydraulic motor.
  • the mixer 35 is a conventional mixer with two shafts which receives, through its upper opening, at the same time as the aggregates and the pulverulent material, the bituminous emulsion through a tube 40, from the water by a pipe 41 and the liquid additive facilitating the coating by a pipe 42.
  • the pipe 40 is connected by a pipe and by a pump to the lower part of the tank 43 containing the emulsion, disposed on the side of the hopper 20 and visible in FIG. 3.
  • the tubing 41 is connected via a pipe and a pump to the lower part of the reservoir 44 containing the water also arranged on the side of the hopper 20 and visible in FIG. 3.
  • the tubing 42 is connected by a pipe and by a pump to the lower part of the reservoir 11 containing the liquid additive favoring the coating of the aggregate.

  • the work carried out by the machine can be controlled by an operator placed on a platform 47 (see FIG. 4) located at the rear of the machine and on which is placed the control console 48 of the various parts of the machine which are not with automatic control.
  • FIG. 5 we see a schematic representation of the engine assembly of the machine which includes in particular the heat engine 5 and the gearbox 6. Between the engine 5 and the gearbox 6 are interposed a clutch 50 and a socket force 51 whose output is coupled by a cardan transmission 52 to the input of a mechanical distribution box 53.
