Definitions

  • the invention relates to a suction excavator for targeted Picking up suction material, especially for lifting Soil on buried lines, with a pneumatic Suction nozzle for picking up the suction material, on the a suction port is arranged at the lower end and the its opposite end in a sump flows.
  • suction dredger picking up suction material developed so-called suction dredger have been using a blower Generates negative pressure and the suction material via a suction nozzle, that hangs on a boom and is adjustable in all directions is sucked into a collection container can. There the suction material is separated from the suction air flow, while still present in the transport air Dust or other particles must be filtered out before the transport air at the outlet side of the fan is blown off.
  • suction power of a suction excavator when used for excavation work to a high degree from is dependent on the skill of the operator.
  • a high suction power is achieved when the lifting movement of the arranged at the free, lower end of the proboscis Suction port in the stroke frequency, i.e. the number of strokes per Minute, and the dwell time on the ground, i.e. the real one Suction time, both depending on the material to be recorded are different, the consistency of each to be absorbed Material can be adjusted.
  • the operator is mostly overwhelmed because they are next to the controller the vertical up and down movement of the suction nozzle must also pay attention to where the Suction port expediently during the downward movement the soil must be put on.
  • the invention has for its object a suction dredger for targeted absorption of suction material, in particular for Digging soil to create the handling the suction port is simplified for the operator.
  • suction nozzle a guide body attached to the proboscis and an axially movable relative to this Has suction mouthpiece that by means of a drive device retractable into and out of the guide body this is extendable.
  • the vertical is up and down Movement of the suction nozzle automated, so that the operator on the point of attachment of the suction mouthpiece can concentrate on the ground, making the Operation of the suction dredger is much easier and at the same time a high suction power can be achieved.
  • the movement of the suction mouthpiece relative to the guide body can be continuous or intermittent.
  • the stroke frequency i.e. the number of strokes of the suction mouthpiece per minute, its Stroke length and also its impact energy on the ground changeable and in particular adjustable by the operator is to adapt well to the respective, to reach the materials available on site.
  • This can in particular by a programmable or programmed Control can be achieved, being for different Soil types the optimal parameter configuration for the stroke frequency, stroke length and impact energy of the suction mouthpiece in a memory already can be held so that the operator appropriate floor type only on a control panel must select using a selector switch.
  • the suction mouthpiece is relative in its axial movement led to the guide body on this, for what in known Way guide rings or strips can be provided can.
  • this has a handle, which preferably as a more spatial surrounding the guide body Handle frame is formed, which on the one hand Handle is given a high spatial stability and it on the other hand as an outer protective cage for the most If necessary, attach the guide body on the outside Additional devices, e.g. Hydraulic lines, drive devices etc., serves.
  • Additional devices e.g. Hydraulic lines, drive devices etc.
  • a piston-cylinder unit As a drive device for the suction mouthpiece a piston-cylinder unit has proven its worth either a compressed air or a hydraulic cylinder can act. To the piston-cylinder unit in front of outer unwanted burdens and especially dirt to protect them with a protective cover be surrounded. The impact energy of the suction mouthpiece to change on the ground are the piston-cylinder unit one or more adjustable pressure boosters assigned, depending on the materials to be absorbed can be optionally switched on or off.
  • a sensor device can be provided on the suction mouthpiece be, by means of which the depth of penetration of the suction mouthpiece in the soil to be recorded.
  • the Sensor device gives a corresponding intrusion signal to the control device. If the control device determines that the depth of penetration is too small and thus the Soil is too hard, it switches automatically the pressure booster or gives the operator of the An optical and / or acoustic signal, so that it switches on the pressure booster manually.
  • the suction mouthpiece points at the bottom, into the ground engaging end in a known manner a toothing to loosen the soil.
  • the teeth of the suction mouthpiece are covered with a cap, which is preferably pivotable or removable on the suction mouthpiece is appropriate.
  • FIG. 1 shows the side view of a suction excavator 1, the has a chassis 2 on which conventional structures, for example, a collecting container 5 are stored.
  • a swiveling telescopic arm 3 At the the rear end of the superstructure is a swiveling telescopic arm 3 provided, which ends in a deflection roller 4.
  • a pneumatic suction nozzle opens into the collecting container 5 10, which runs over the guide roller 4 and on his lower end carries a suction port 11.
  • Using negative pressure is a suction medium, usually soil, with Help of the suction nozzle 11 added and by the Suction nozzle 10 transported into the collecting container 5.
  • the suction nozzle shown in detail in Figures 2 and 3 11, at the bottom of the pneumatic proboscis 10 is attached, includes one with the proboscis 10 connected tubular guide body 12, the is surrounded on the outside by a grip frame 14.
  • a Operator can guide body 12 on handle frame 14 capture and in a known manner along with the Move the proboscis 10 freely horizontally and / or vertically, supported by the swivel telescopic arm 3 becomes.
  • a tubular at the lower end Suction mouthpiece 13 inserted into the guide body 12 retractable and axially extendable from this is.
  • a drive for the movement of the suction mouthpiece 13 is at least on the outside of the guide body 12 a compressed air cylinder 15 with a pressure booster 18 provided, by means of which the suction mouthpiece 13 between the retracted position shown in Figure 2 and that shown in Figure 3, extended down Position is movable.
  • toothing 16 designed with which the suction mouthpiece 13 in the Intervene and loosen the soil.
  • Tooth 16 is assigned a removable cap 17, with which the gearing can be covered.
  • the operator When operating the suction excavator 1, the operator detects the Guide body 12 on the handle frame 14 and leads it briefly above the area of the earth to be recorded, whereupon the suction mouthpiece 13 automatically as a result of Air cylinder 15 moves down with the ground comes into contact and after a short time from it again lifts off and is drawn into the guide body 12.
  • the stroke frequency of the suction mouthpiece 13 can be its Stroke length and thus the impact energy on the ground preset via a control device 6 (FIG. 1) will.
  • a selector switch 7 is provided on the handle frame 14, via which the operator can choose the pressure booster 18 can turn on or off. In addition, the Operator the control device 6 via the selector switch 7 adjust to the medium to be sucked up.
