Definitions

  • the invention relates to a paver with a screed and a reservoir behind the screed, wherein the reservoir has a split spreader with a metering, and wherein the road paver another reservoir is arranged, which is filled via filler with grit, wherein the grit from the other reservoir is transported to serving as a storage grit spreader.
  • the distributor can be used as a single or double disc spreader as attachments to rollers.
  • the driving elements of this spreader are flat or outwardly tapered circular centrifugal discs which rotate at constant speed about a vertical axis of rotation. So that the litter material can be accelerated tangentially to disk peripheral speed, ribs are welded on the upper side of the disk, on which the split grains slide outwards due to the effect of the centrifugal force.
  • the scattering width is determined in these scatterers by the discharge speed, the discharge height, number of slices and the air resistance to the thrown granules. Due to the simple design, the low susceptibility to interference, the convenient cleaning options and the high area performance, this distribution principle has found a great application in practice.
  • a disadvantage of this type of splitting is an uneven spreading pattern, which must be compensated with a high excess amount of litter material.
  • Out FR 79 30 414 is a free fall chip spreader with metering known as trailed device.
  • the uniformity of the scattering pattern achieved over the working width is far superior to the Schleundersplittstreuer.
  • the disadvantage here, however, is that the trailed device must be moved with a separate vehicle on the purpose of this pre-compressed hot asphalt layer, which complicates the subsequent rolling of the grit.
  • DE-GM 73 29 587 a freefall chip spreader with metering roller and reservoir is described, which is arranged as an attachment to a road roller.
  • the metering roller is driven separately and can be adjusted during use by the roller driver.
  • a disadvantage is that for the entire width of the screed of the paver several rolling tracks are required, each with new approaches that make an overlap of grit required, whereby no uniform scattering characteristic is achieved.
  • Out DE 41 18 997 A1 is a self-propelled grit spreader with a receptacle known, which has to achieve a uniform splitter discharge in exactly metered amount a vibrating chute as a discharge device, which is mounted below a discharge gap on the reservoir.
  • the vibrating channel consists of a middle part with adjustable end sections, which allows an adjustable spreading width.
  • the vibrating trough is held independent of the inclination of the roadway in a predetermined desired position.
  • the disadvantage here is that the Streingaumaschinefug, both in terms of the discharged per square meter road surface chippings, as well as in terms of uniform grit distribution, significantly depends on the nature of the material to be spread. In particular, the particle size distribution, the moisture and temperature of the material to be spread and its surface quality influence the scattering pattern.
  • a self-propelled split spreader which has transverse to the direction of travel adjustable width in the working width with a vibration exciter and conveys the chippings to at least one discharge edge and throws him there.
  • the scattering plate has a wave-like profiling at the splitter-carrying surface, at least towards the discharge edge. Furthermore, the scattering has a quantity measuring device that counts chippings contactless.
  • a disadvantage of all the aforementioned devices for chippings is that the rolling of the chippings takes place at the earliest after the first roller gear and not at the optimal time directly during the mixing material installation by the paver. As a result, not all of the grits with the required adhesion are incorporated into the asphalt surface layer, which greatly reduces the quality of the split road surface with respect to the initial roughness and causes increased damage, especially on windscreens, due to loose chippings.
  • the disadvantage here is that a separate device is required for the distribution of the chippings and that a control of the dosage of the spread rate is not possible.
  • the invention has for its object to provide a device of the type mentioned, with a uniform grit layer over the entire width of the spreader is made possible.
  • FIG. 1 a screed 1 is shown behind which a spreader and a surface vibration device 13 is located.
  • a dryer device which sucks the heating air of the screed heating by a Schuzziabsaugung 16 and blows BankLiteleitprofile 17 in the litter storage container 8.
  • Under the metering roller 10 is a spreading agent cleaning device with two cleaning brushes 11 and integrated hot air dust extraction 19, which supplies the suctioned air by means of a blower 18 to a dust collector. This produces a dust-free, clean and dry litter material layer 15.
  • a tracked surface vibrator 13 the scattered spreading material is shaken into the surface of the asphalt layer 14.
  • the spreader is located directly behind screed 1 and before the pressure bars 6 and 7.
  • an emulsion can be sprayed onto the litter to increase the adhesion force via a metering pump 23 and injection nozzles 21.
  • the container 22 serves as a storage container and is designed as a module attachment.
  • the application rates of metering roller 10 and the injection nozzle 21 are proportionally controlled in dependence on the operating speed of the paver.
  • the desired values of spread rates of the metering roller 10 and the injection quantities of the nozzles 21 can be preset via a remote control.
  • the actual value of the application rates is displayed via a digital display.
  • FIG. 3 shows a screed 1, in which the scattering device between rammer 3 and Bohle 1 is arranged.
  • the screed plate 2 of the screed 1 is formed so that the collection of litter material is ensured under the screed plate 2.
  • the surface structure of the incorporated by the compression units vibrator 5 and pressure bars 6 and 7 grit can be adjusted independently by changing the metering slide 9 and metering roller 10 and the vibration frequency and amplitude of the compression units.
  • FIG. 4 a spreader is shown, which is arranged between the front wall 4 and rammer 3 of the screed 1 as an add-on module.
  • a spreader is shown, which is arranged between the front wall 4 and rammer 3 of the screed 1 as an add-on module.
  • facilities are installed which make it possible to block the spreading of spreading material in the overlapping area.
  • the device is suitable for every occurring screed broadening designed and can be widened just as it is known from screeds ago.
  • Screed 1 shown has two rammers 3 and 24, between which a receiving space 25 is arranged for spreading material or in which the device is mounted. If the receiving space 25 is used as a filling space for spreading material, a distribution screw 26 is arranged above the receiving space 25. With the setting of the ram stroke of the two rammers 3 and 24 and the position of the rammer to each other, the strength of the spreading material layer 15 can be determined. This positioning can be finely adjusted by means of a linear adjustment 27. It is also possible to provide the spreader with broadening parts with which the working width as well as the screed 1 can be changed.
  • FIG. 6 is arranged on the screed 1 as a device for fine metering a vibrating distributor bar 28 which is connected to a second vibration device 29.
  • a vibrating distributor bar 28 which is connected to a second vibration device 29.
  • the amount of scattering material to be distributed can be adjusted. It is also possible to run the vibratory distributor bar 28 as a conveyor belt distributor.
  • FIG. 7 is a cross-section of an adjusting axis 30 rotatable and lockable vibration distribution bar 28 is shown, whose surface is provided with a profiling 31, whose structure is arranged in both directions.
  • the adjustment axis 30 extends approximately parallel to the roadway transverse to the direction of travel.
  • the vibration distribution bar 28 is rotatable about an axis designated z, which extends approximately in the direction of travel. It is also possible to run the vibratory distributor bar 28 as a conveyor belt distributor.
  • FIG. 8 which represents an embodiment of the invention, the arrangement of a further storage container 33 for spreading material on a paver 32 is shown.
  • the further reservoir 33 has a filler neck 34 for filling with grit.
  • a screw conveyor 35 is arranged, the spreading material to a serving among other things as a reservoir 8 middle split spreader 36, which is attached to the screed 1, transported.
  • a portion of this material to be spread is from the middle split spreader 36 in a left and a right split spreader 37, 38, which are each arranged below the middle split spreader 36, transported and distributed by these finely dosed as a spreading material layer 15.
  • FIG. 9 a device is shown with adjustable in an adjustment 42 working width, the middle split spreader 36 are attached to the screed 1 and the left and the right split spreader 37, 38 on extension parts of the screed 1.
  • the middle split spreader 36 is located above the left and right split spreaders 37, 38, wherein the middle split spreader 36, each with a partial length with the left and the right split spreader 37, 38 covered.
  • the middle split spreader 36 finely dosed litter falls directly on the asphalt layer 14, in the covering areas, the litter falls from the middle split spreader 36 first in the left and right split spreader 37, 38, is distributed in these each transverse and then finely dosed from these immediately on the asphalt layer 14, so that a uniform grit layer 15 is made possible with variable roadway width.
  • a middle split spreader 36 is shown in the upper part, which serves as a reservoir 8.
  • this middle split spreader 36 is a distribution screw 26, which both distributes the spreading material in this middle split spreader 36 and pushes out of the open ends open on both sides; the grit pushed out of the ends open at both ends initially falls into a left and a right grit spreader 37, 38.
  • the left and right split spreader 37, 38 are disposed below the central splitter spreader 36 and also have in their interior in each case a distributor screw 26, with the grit inside the grit spreader 37, 38 first is distributed across.
  • the lateral split spreaders 37, 38 also serve as a reservoir 8, in which a predosing of the material to be spread takes place.
  • a metering roller 10 is arranged in each case, with the aid of which a fine metering of the material to be grit located in the grit spreaders takes place.
  • the fine-dosed grit from the middle splitter spreader 36 falls directly onto the asphalt layer 14, while in the covering areas between the middle grit spreader 36 with the lateral grit spreaders 37, 38 the finely dosed grit first falls into the lateral grit spreaders 37, 38.
  • a fill level sensor 54 is arranged, which serves to monitor the amount of grit in each splitter spreader 36, 37, 38.
  • the level sensors 54 are coupled to a control device, with the help of which, if necessary, the speed of the distributor screws 26 or the supply of grit to the central split spreader 36 can be changed.
  • a sensor 57 is arranged on the middle split spreader 36, with which an angle of this central split spreader 36 can be determined by two axes each; this sensor 57 is also connected to the control device.
  • the overlying middle split spreader 36 visible in his view.
