Definitions

  • the present invention relates to a mobile working device according to claim 1.
  • the mobile implement z. B. on a Unimog vehicle brand Mercedes-Benz A frame is installed at attachment points D60 and D69 of the Unimog. This is prepared for mounting a support frame for a milling unit. Above the Unimog frame is a solid subframe constructed and braced with the Unimog frame. In this and in the base frame a support frame for the milling unit is installed. To the rear is a cargo area with side walls.
  • the milling unit comprises a cutting wheel, which is made as a disc made of steel. On the circumference of the cutting wheel 12 segment pieces are screwed to which the required milling tools are welded.
  • the Ausschiebevorraum for milling unit is also installed. With this, the milling unit is moved hydraulically from a transport to a working position by about 300 mm to the right outside.
  • a hydraulic unit is built behind the Unimog cab on the subframe.
  • the hydraulic unit consists of a hydraulic pump, a hydraulic tank, filter, cooler and the required overpressure and directional valves.
  • the Unimog's N05 engine PTO drives the hydraulic pump with a PTO shaft.
  • the speed of the cutting wheel can be infinitely adjusted from a control panel in the cab.
  • the positioning movements are controlled by electro-magnetically operated black and white control valves.
  • the oil supply for this purpose is provided by circuit 1 of the Unimog hydraulics.
  • the actuation of the positioning movements is carried out by a joystick, or switch of a control panel which is installed in the Unimog cab and further includes all switches for the operation of the milling unit. With such a mobile implement, the milling of slots and the simultaneous introduction of a barrier film in the slot in one operation is possible.
  • Fig. 1 illustrated in a schematic, partially broken side view of a first embodiment of the mobile working device according to the invention 1.
  • Wie aus Fig. 1 can be seen, the mobile implement 1, a milling unit 3, which is fixed to a support frame 2 and a disk-shaped, rotatable cutting wheel 4 has.
  • the milling unit 3 is driven by a likewise attached to the support frame 2 hydraulic unit 8, which in turn via a (not shown here) external drive of the mobile implement 1 is driven.
  • a direction of travel and working direction of the mobile implement 1 is indicated by an arrow R.
  • the milling unit 3 has a cover 22 attached thereto, which covers the cutting wheel 4 from above almost semi-circular.
  • a reamer 11 is arranged, of which in Fig. 1 only one reamer 11 is visible.
  • the milling unit 3 has a lifting device 6 and a Ausschiebevorraum 5, which are connected to the cutting wheel 4.
  • the ejection device 5 By means of the ejection device 5, the milling unit 3 is moved by a retracted to the mobile implement 1 transport position on a laterally extended from the mobile implement 1 or projecting working position.
  • the lifting device 6 By means of the lifting device 6, the milling unit 3 is moved from a raised to the mobile implement 1 transport position to one of the mobile implement 1 downwardly extended or lowered working position.
  • the mobile implement 1 By the extended to the working position or lowered and rotatably driven milling unit 3, the mobile implement 1 at a slow forward travel in the direction of R milling a slot 10 corresponding to the width of the milling tools in the soil next to a roadway. In this step, the roots of trees and shrubs located in the milling area are simultaneously severed by the sharp-edged milling tool 10.
  • the scrapers 11 located on the front of the cover 22 serve to laterally redirect and scrape the milled out earth material to prevent the earth material from falling back into the milled slot.
  • FIG. 2A to 2C show individually and in different views.
  • Figs. 2A, 2B and 2C show a side view, top view and rear view of the milling unit 3 of the working device according to the invention 1.
  • the same components are here with the same reference numerals as in Fig. 1 characterized.
  • Fig. 2A to 2C The detailed drawings described above, the individual components or components of the Fräsaggregats 3 described above are clearly visible.
  • excavation of a trench can be carried out more quickly, with less manpower and thus more cost-effectively, as compared to the conventional excavators or other equipment used, due to the lower excavation amount.
  • intervention in the landscape and nature is kept to a minimum.
  • a film laying device 7 of the mobile working device 1 according to the invention is attached to the cover 22 by means of a gimbal 12.
  • the film-laying device 7 has a film holder 13 and a film retractor 14, which can be raised or lowered by means of a hydraulically operated boom 15.
  • the film-laying device 7 winds a roll 13a arranged on the film holder 13 with film material 21 via a film inserter 14 and deflects this film material 21 in such a way that the film material is inserted vertically into the slot milled by the milling unit 3. This eliminates any otherwise required manual activity that was previously required for inserting the film material 21 as a barrier film for a renewed root growth.
  • FIGS. 3A to 3C A detailed representation of the individual components or components of the film-laying device 7 is shown in FIGS. 3A to 3C illustrated, in which like components here again with the same reference numerals as in Fig. 1 Marked are.
  • the mobile implement 1 also has a compressor 16 which is attached to a rear linkage 17 and is also driven by the hydraulic unit 8.
  • a filling screw 18 which runs counter to the working direction R, is arranged, which can be hydraulically driven and inclined.
  • the milled out earth material is backfilled in the slot after insertion of the barrier foil 21 against the root growth in the subsequent step.
  • the expensive and time-consuming dredging to fill the otherwise usually produced larger trenches can be replaced.
  • the reconsolidation of the introduced earth material takes place by means of the compressor 16.
  • Fig. 4 illustrates a schematically simplified side view of a second embodiment of the working device according to the invention 1.
  • This second embodiment differs from the first in Fig. 1 illustrated embodiment in that the mobile implement 1 only the Ver Schollschnecke 18, but no compressor 16 which is fixed to the rear linkage 17.
  • the same components are in turn here with the same reference numerals as in Fig. 1 characterized.
  • This second embodiment can be used when, due to the nature of the milled soil material or the topographical conditions next to the road, an immediate reconsolidation of the filled slot is not required or possible.
  • Fig. 5 illustrates a schematically simplified plan view of a third embodiment of the working device 1 according to the invention, wherein the same or functionally identical components are again denoted by the same reference numerals as in the first and second embodiments.
  • a Schlagverêtr device 23 in the direction of travel behind the cutting wheel 4 and the film laying device 7 is arranged.
  • the impact compressor device 23 is attached to the not visible rear linkage 17 of the mobile implement 1.
  • the impact compressor apparatus 23 further includes a compressor arm 24 pivotally attached to a bracket 28 fixed to the hitch 25 and driven by a drive motor 30.
  • the impact compacting device 23 has a filling pile 31 for filling the milled slot.
  • a connecting rod 29 is rotatably mounted on the compressor arm 24, the motor-side end 29a is attached to a motor driven pulley 32 eccentrically.
  • the drive motor 30 When the drive motor 30 is running, the rotational movement of the motor driven pulley 33 is thus converted into an angular pivoting or recuperation and striking movement of the compressor arm 24.
  • Fig. 6 is top dead center of this pivoting movement illustrated by the dashed lines shown compressor arm 24 together with dashed lines shown connecting rod 29, while the bottom dead center is shown by the illustrated with solid lines compressor arm 24 together with the connecting rod 29. Due to the cyclical impact movements of the compressor arm 24, the soil material filled in the slot is recompressed.
  • This third embodiment can be used when, due to the nature of the milled soil material, recompression is required over the entire depth of the slot (rather than just at the surface).
