Definitions

  • the invention relates to an excavator for targeted excavation of soil above buried pipes.
  • the invention has for its object to provide an excavator, in particular for the targeted excavation of soil above buried lines, that the areal expansion of the construction site and the excavation is limited to the absolutely necessary extent and the risk of damage to the exposed line is completely avoided, but at least is reduced to a minimum.
  • an excavator which consists of a pneumatic suction nozzle, a hollow cylindrical tool forming the suction piece for breaking up the soil, a collecting container for the sucked-up soil, into which the suction nozzle opens and in which the soil is separated from the suction air flow, a suction fan connected to the collecting container and at least one filter arranged between the mouth of the suction nozzle in the collecting container and the suction fan.
  • the soil is loosened at the desired point and the soil located inside the breaking tool is conveyed into the collecting container by means of the suction nozzle or the suction blower. There, the soil is separated from the suction air flow, while dust still present in the transport air is filtered out before the transport air is blown off at the outlet side of the blower.
  • the breaking tool works like a core drill into the ground and all loosened material is immediately extracted from the work site. The excavated material collects in the container and does not have to be landfilled at the construction site. Dust and dirt pollution at the construction site is reduced to a minimum.
  • the proboscis can be easily controlled in the working depth, for example by its own weight, which can still be partially compensated for.
  • the excavation site can also be easily inspected so that damage to the lines is avoided.
  • the overburden can either be driven to a landfill or, by appropriately designing the collecting container, can be used again directly to fill the hole.
  • a preferred embodiment is characterized in that the suction nozzle is connected to the collecting container via an extension arm and can be raised and lowered by means of the extension arm and can be pivoted in a horizontal plane.
  • the proboscis is preferably made of flexible material.
  • the suction nozzle is attached with its container-side end to a collar of larger diameter protruding into the collecting container at its inner end.
  • the suction nozzle is preferably guided over a hose reel mounted at the free end of the boom so that it can carefully follow all movements of the boom.
  • the proboscis is provided with supply air openings near the breaking tool or the hollow cylindrical breaking tool.
  • the supply air openings can be designed as nozzles that extend in the conveying direction and narrow in this direction.
  • Several supply air openings are advantageously arranged in a ring.
  • water nozzles are arranged in the area of the connection of the suction nozzle to the container and are directed into the flow.
  • air nozzles are directed into the air flow in the area of the filter or filters on the suction side of the collecting container. It is expedient if the filter on the suction side is a surface filter and the air nozzles are arranged on the outflow side of the filter and directed at it, optionally intermittently and / or one after the other.
  • the water nozzles assigned to the filter arranged there on the suction side of the container ensure that even the last dust particles are bound and separated within the collecting container, whereby the alignment of the water nozzles on the surface filter also enables an intermittent or continuous cleaning of the filter.
  • a silencer can be arranged at least in the exhaust air duct of the blower. Such is also advantageously located between the collecting container and the blower.
  • the material can be separated from the transport air in various ways. It is advantageously provided that an apron which deflects the flow downward is arranged inside the container before the connection of the suction nozzle as a separator.
  • the apron can consist entirely or partially of metal and / or rubber, plastic or the like. In particular, the formation of a rubber-like material is recommended because of the lower wear and the low noise.
  • the collecting container can be tipped backwards or sideways about a horizontal axis for emptying, so that the separated excavation can be emptied easily if required.
  • the hollow cylindrical breaking tool has at its lower end an annular toothing which forms the breaking tools.
  • the design is advantageously made such that the teeth of the toothing are adjusted with respect to the axis of the hollow cylindrical breaking tool so that when it rotates the loosened soil is deflected inwards.
  • the toothing is arranged on a ring which is mounted on the breaking tool and can be set in torsional vibrations about its axis.
  • the soil is loosened in a ring and sucked in within the ring. In the case of relatively loose soil, this breakout tool design is sufficient.
  • breaking tools can be supported by the fact that pneumatic or hydraulic high pressure nozzles are arranged on the outside or inside of the hollow cylindrical breaking tool.
  • the high pressure nozzles can help loosen and loosen the soil. At the same time, they ensure dust binding at the place of work.
  • Breaking tools of different diameters can be attached to the proboscis in order to be able to penetrate between buried lines, in particular with smaller diameters.
  • a compressed air lance with one or more compressed air nozzles is provided, by means of which the lines exposed by the breaking tool can be cleaned of soil still lying on or loosely adhering.
  • the excavator shown in FIG. 1 has a chassis 1 on which a collecting container 2 with a suction nozzle 3 connected at the rear and a suction fan 4 are arranged.
  • the suction fan 4 is connected via a line 5 with a built-in silencer 6 in the upper region of the collecting container.
  • a silencer 8 is also arranged in the exhaust air line 7 of the blower 4.
  • the suction nozzle 3 opens into the collecting container via a collar 18.
  • the proboscis 3 consists of a flexible, stiffened material and is guided downwards via a hose reel. At its lower end, the proboscis 3 has an opening tool, generally designated 10, which is surrounded by a protective basket 11.
  • the hose reel 9 is freely rotatably supported at the free end of a boom 12.
  • the boom 12 can be raised and lowered on a column 15 by means of a lifting cylinder 13 about a horizontal transverse axis 14.
  • the column 15 in turn can be rotated about a vertical axis by means of a swivel motor 16, so that the suction nozzle can be moved into the positions shown in broken lines in FIGS. 2 and 3.
  • the breaking tool has an annular toothing 17, the details of which will be described later.
  • the rupture tool designated as a whole by 10, as well as the toothing 17 are hollow-cylindrical, so that the detached from the toothing Soil is sucked by means of the negative pressure generated by the suction fan 4 in the collecting container 2 and in the suction nozzle 3 and transported into the collecting container.
  • an apron 19 Arranged within the collecting container 2 immediately behind the mouth of the suction nozzle 3 is an apron 19 which acts as a separator and which deflects the transport air and the material transported by it downward.
  • the apron 19 can have rubber-elastic tabs 20 at least in the lower region.
  • one or more water nozzles 21 are arranged in order to bind and separate at least a large part of the carried dust.
  • the transport air passes through a surface filter 22 into the suction line 5.
  • a device for cleaning the filter which has a plurality of air nozzles 23 directed against the filter and on the one hand binds further dust and on the other hand cleans the surface filter.
  • the filter can have a grid-like structure, in particular consist of a metal grid 24. Above the metal grid 24, a plurality of nozzle tubes 25, which have the air nozzles 23, are arranged in parallel. The nozzle tubes 25 can be controlled intermittently or continuously, so that the surface filter 22 is cleaned discontinuously or continuously.
  • the collection container 2 is arranged on the chassis 1 so that it can be emptied by a tilting movement. For this purpose it can be divided if necessary, to only have to tip the lower part of the container. Provision can also be made for the connection units, such as the proboscis, suction line, etc., to remain stationary.
  • the collecting container 2 can either be tilted backwards about a horizontal transverse axis 27 (FIG. 1) or else about horizontal longitudinal axes 28 on one or the other side of the chassis 1 (see FIG. 4).
  • FIG. 7 shows the suction nozzle 3 in the region of the hollow cylindrical breaking tool 10.
  • annular supply air nozzles 29 which extend from bottom to top in the direction of transport and narrow in this direction. Air is sucked in laterally through these nozzles 29, which enters the breaker tool 10 in an injector-like manner and supports the conveying of the material, in particular prevents the feed stream from being loaded too heavily and thereby avoids clogging of the suction nozzle or suspension of the conveyance.
  • the teeth of the toothing 17 are pivoted or adjusted relative to the axis of the breaking tool in such a way that when the breaking tool is turned, the material loosened by the teeth 30 is conveyed inwards.
  • the loosening of the soil can also be supported by high-pressure nozzles 31, which are supplied with compressed air or pressurized water.
  • the suction nozzle 3 is designed at its lower end so that break-open tools 32 with different, in particular smaller, diameters can also be used, as shown in FIG. This makes it possible to penetrate gaps between installed cables.
  • the toothing 17 is preferably arranged on a separate ring 33 which is guided or mounted within the hollow cylindrical breaking tool 10 and which can be set in torsional vibrations by means of a compressed air motor 34 or the like.
  • the compressed air motor 34 has on its output a cam 35 which engages in a corresponding recess in a shoulder 36 on the ring 33.
  • FIG. 11 shows an embodiment in which a transverse worm mill 37 is mounted within the breaking tool 10, which in turn is preferably driven by a compressed air motor 38.
  • the screw flights are designed in such a way that they transport the soil loosened by them to the center, for example one screw flight 38, 39 is provided in each case, which loosen and promote the soil from the outside inwards.
  • FIG. 12 shows an additional device in the form of a compressed air lance 40, which is connected via a line 41 to a compressed air source and has at its end several nozzles 42, three in the exemplary embodiment shown.
  • a compressed air lance 40 By means of the compressed air lance 40, material adhering or resting on the pipelines can be blown off.
