Fig. 1 is an example used for compacting asphalt material for a roadway self-propelled soil compactor 10 in principle representation shown in side view.
the soil compactor 10 includes a machine frame 12 formed, for example, as a hinged frame, on which two compressor rolls 14, 16 are rotatably supported about respective compressor roll rotation axes.
the two compressor rollers 14, 16 are arranged on the machine frame 12 in a direction of movement of the soil compactor 10 consecutively. For example, one of them may be provided on a front end and one of them on a rear end of the machine frame.
each of the compressor rolls 14, 16 may be constructed as a roll formed with a roll shell of steel material passing through the compressor roll rotational axis direction.
one or both of the compressor rolls 14, 16 could basically also with a plurality of consecutive in the direction of the respective compressor roller axis of rotation individual wheels, for example, with pneumatic tires, be formed, which then define in their entirety in the context of the present invention, a compressor roller.
each wheel of such a group of juxtaposed wheels could also be considered as a compactor roller in the sense of the present invention.
the drive unit ie for example a diesel drive unit, may be carried on the machine frame 12.
the various system areas to be driven of the soil compactor 10 with corresponding drive energy for example via a pressurized fluid circuit, a generator / motor or the like can be fed.
the soil compactor 10 includes a liquid storage / dispensing system, generally designated 22. From this liquid storage / dispensing system, its structure and operation with reference to the following Fig. 2 described in detail are in Fig. 1 two liquid main tanks 24, 26 are visible, which are each supported on a compressor roller 14, 16 on the machine frame 12. Furthermore, in Fig. 1 schematically a liquid intermediate storage 28 recognizable, which is supported on the machine frame 12 in the area 20 under the driver's cab 18, ie in that area in which the drive unit can be accommodated. Furthermore, in Fig. 1 schematically from the liquid main memories 24, 26 to the intermediate liquid storage 28 leading liquid main lines 30, 32 recognizable.
the liquid contained in the liquid main memories 24, 26 can be discharged to the liquid buffer 28 and then described in the following Way to be fed to liquid-fed system areas of the soil compactor 10.
These system areas include the two compressor rolls 14, 16, the surface of which, in particular, must be wetted with liquid during an asphalt compacting operation in order to prevent the adhesion of asphalt material to the compacting rolls 14, 16.
Another with systemic fluid, so for example water, to be fed system area is in Fig. 1 shown in association with the compressor roller 14.
This system area comprises an edge processing device 34, which is arranged laterally next to the compressor roller 14 and can be used for processing a roadway edge.
This edge processing device 34 comprises an edge-machining wheel 38 that can be adjusted, for example, by a hydromechanical drive 36 in the vertical direction, which can be formed as a bevel gear and can press and beveled in contact with the roadway edge to be machined.
the edge processing wheel 38 can be brought into a suitable height positioning and driven for rotation for performing such edge processing operation.
the soil compactor 10 may include two such edgers 34, each on one side thereof, as viewed in the direction of the compressor roller axes of rotation.
the compressor roller 16 provided at the other end region of the machine frame 12 is also attached to the compressor roller 16 in FIG Fig. 1 unrecognizable side of the soil compactor 10 is associated with such a peripheral processing device, so that regardless of the orientation or of the direction of movement of the soil compactor 10 each have an edge region can be processed with the associated edge processing device.
Fig. 2 are the two main liquid storage 24, 26 can be seen, each in its upper region, for example by a closure 40, 42, z. B. screw lockable opening 41, 43 have can.
These openings 41, 43 or the respective associated closure 40, 42 can serve on the one hand for venting the respective main liquid storage 24, 26 in a filling process, on the other hand could basically via these openings 41, 43 with each removed closure 40, 42 and a filling of the liquid main memory 24, 26 take place.
the liquid main memory 24 associated main liquid line 30, which leads from a lower portion of the main liquid storage 24 to the liquid buffer 28.
the liquid main line 32 assigned to the main liquid store 26 leads from a lower area of the main liquid store 26 to the intermediate liquid store 28. It can be seen that the two liquid main lines 30, 32 in an upper area of the liquid intermediate store 28 open into this. Since the intermediate liquid reservoir 28 is arranged below the two main liquid reservoirs 24, 26 in the vertical direction, it is ensured that the main liquid reservoirs 24, 26 can be completely emptied to the liquid intermediate reservoir 28 via the liquid main lines 30, 32.
the intermediate liquid reservoir 28 is further associated with a filling flange 44 provided in a lower region on this.
This filling connection 44 which is designed, for example, as an inclination angle connection or pressure pipe connection, preferably so-called C-pipe connection, can be used to fill the two main liquid reservoirs 24, 26 via the liquid intermediate store and the main liquid lines 30, 32 leading to it ,
the liquid main line 30 or 32 assigned to a respective main liquid storage 24 or 26 can be used not only for emptying the main liquid storage 24 or 26, but also for filling it.
the filling port 44 is constructed so that it is suitable for pressure filling, it is thus possible to fill the two main liquid storage parallel to each other in a very short time.
the case from the Liquid main storages 24, 26 displaced air can escape via the openings 41, 43 provided in the upper region of these main liquid reservoirs 24, 26 or the closures 40, 42 associated therewith and having respective venting arrangements.
a closable by a closure 46 liquid discharge opening 45 is also provided. Via this liquid discharge opening 45, liquid contained in the main liquid reservoirs 24, 26 or the main liquid lines 30, 32 can be drained off. Furthermore, a liquid filter arrangement can be carried on the closure 46 closing off the liquid discharge opening 45, which can be designed as a screw closure, so that it can be easily removed from the liquid intermediate store 28 and cleaned when the closure 46 is removed.
a fluid delivery device 48 which is designed, for example, as a water tap, is furthermore provided. This can be used to make it possible for personnel working in the area of the soil compactor 10, for example, to clean their hands with the liquid stored in the liquid main storages 24, 26 or also in the liquid intermediate store 28.
the liquid buffer 28 may be further associated with a level sensing arrangement.
the latter can, for example, operate in a pressure-dependent manner in the intermediate liquid reservoir 28, so that it can be concluded on the basis of the detected liquid pressure to what extent the liquid main reservoirs 24, 26 positioned above the liquid intermediate reservoir 28 are still filled with liquid.
a liquid intermediate line 50 leads away to two first liquid pumps 52, 54 and a second liquid pump 56. These three liquid pumps 52, 54, 56 are connected in parallel to the liquid intermediate line 50 and thus take liquid in parallel from the liquid intermediate line 50 on.
the first two fluid pumps 52, 54 are connected to each other in parallel to a first fluid discharge line 58.
the first liquid discharge line 58 leads away from the first two liquid pumps 52, 54 and is branched into two first branch lines 60, 62. Each first branch line 60, 62 leads to a respective first liquid dispensing unit 64, 66.
the first liquid dispensing unit 64 is associated with the compacting roller 14 and comprises a plurality of liquid in the direction of the compressor roller axis of rotation and in the conveying operation of the first liquid pumps 52, 54 liquid on the surface These may be provided on a distributor tube 70 positioned along the compressor roller 14, preferably along a stripper also associated with the compressor roller 14, the compressor roller 14.
the liquid sprayed onto the compactor roller 14 by the liquid dispensing nozzles 68 in an area above a scraper is passed through the surface of the compactor roller 14 adjacent wiper additionally distributed so that a full-surface wetting of the compressor roller 14 is ensured with the output from the first liquid discharge unit 64 liquid.
first liquid dispensing unit 66 is associated with the other compressor roller 16.
This first liquid dispensing unit 66 which interacts with the compacting roller 16, also comprises a distributor tube 72, which preferably extends over one of the compactor roller 16 and has a plurality of liquid dispensing nozzles 74 provided thereon.
the liquid contained in the main liquid reservoirs 24, 26 and gravitationally flowing via the liquid main lines 30, 32 into the liquid intermediate reservoir 28 can be withdrawn from the liquid intermediate reservoir 28 via one of the first liquid pumps 52, 54 and via the first liquid discharge line 58 and the first two branch pipes 60, 62 are conveyed to the first liquid discharge units 64, 66.
the dimensioning of the first liquid pumps 52, 54 is selected such that each one of them has a sufficient delivery capacity in order to supply both liquid discharge units 64, 66 with sufficient liquid.
the provision of two mutually parallel connected first fluid pumps 52, 54 ensures that in case of failure, one of the pumps can be continued immediately with the other, so that an interruption in the fluid supply to the two fluid delivery units 64, 66 can be avoided.
the second liquid pump 56 which likewise withdraws liquid from the liquid intermediate store 58 via the liquid intermediate line 50, discharges the liquid conveyed by the latter into a second liquid discharge line 76.
the second liquid discharge line 76 branches into two second branch lines 78, 80. Every second branch line 78, 80 leads to a second fluid delivery units 82 and 84, respectively.
Each of these second fluid delivery units 82 and 84 may include one or more fluid delivery nozzles 86, 88. Via the liquid dispensing nozzles 86, 88, the liquid conveyed by the second liquid pump 56 can be dispensed in the direction of a respective edge processing device 34 or 34 '.
the liquid can be sprayed onto the respective edge-machining wheel 38 or 38 'of the edge-processing device 34 or 34', while it rotates about a rotation axis in the edge-machining process.
each of these two edge processing devices 34, 34 ' can each be assigned to one of the two compressor rollers 14, 16, advantageously distributed to the two sides of the soil compactor 10.
the second liquid pump 56 By means of the second liquid pump 56 connected in parallel to the first two liquid pumps 52, 54, liquid can be conveyed to the second liquid discharge units 82, 84, independently of the operation of the first liquid pump 52, with the required or advantageous amount. Since, in general, significantly less liquid has to be conveyed to the edge processing devices 34, 34 'in the edge processing operation than is required for the two compressor rollers 14, 16, the second liquid pump 56 can be designed with a lower maximum delivery rate, ie delivery volume per unit time The result is that, if during a edge processing operation, a liquid supply to the first two liquid dispensing units 64, 66 is not required, much less energy must be expended to promote liquid, since only a comparatively small dimensioned fluid pump, namely the second fluid pump 56, is to operate. Furthermore, the second liquid feed pump 56 can also be designed or activated for another conveying operation, for example an intermittent conveying operation.
FIG. 1 and 2 described soil compactor 10 contains a variety of particularly advantageous in combination, but also individually positive impacting aspects.
this provides the possibility of filling one or more main liquid reservoirs 24, 26 via a filling connection 44 assigned to them, in particular when carrying out a pressure filling operation, for which purpose the aspect that the main liquid lines 30, 32 are not only used for emptying the main liquid reservoir is utilized 24, 26, but also for filling the same can be used.
Another very advantageous aspect of the ground compactor 10 according to the invention is that the various system areas to be supplied with liquid, generally water, in which there are different requirements with respect to the required amount of water, namely the compactor rolls 14, 16 on the one hand and the edge processing devices 34, 34 '.
first liquid pumps 52, 54 and a second liquid pump 56 can be fed independently of each other by these system areas.
Each of these system areas or each of these feed pumps 52, 54, 56 can thus with for each operation optimal design aspects, in particular with a sufficient maximum delivery capacity are constructed without this brings a deterioration in the functionality in the liquid supply to a respective other system area with it.
both main liquid reservoirs 24, 26 can be filled via a common filling connection 44 can also be realized if each main liquid store 24, 26 is assigned several, for example two, liquid main lines. From each main liquid storage 24, 26 could then lead, for example, a main liquid line to the liquid reservoir 28, while in each case a different main liquid line to the then not for example provided on the liquid reservoir 28 filling port 44 could lead, so that these liquid main lines then the main liquid reservoir 24, 26 are filled together can.
