Definitions

  • the invention relates to a Erdbohrvortechnisch with a rotary drive and connected to the rotary drive via a shaft drill head.
  • earth augers which have correspondingly large-sized Spindelbohrkexcellent and provide based on the Archimedian principle for a vertical excavation.
  • Such motor driven equipment is heavy and expensive.
  • a drilling device for the introduction of boreholes is to be taken into the soil, which provides a connected to a vacuum source outer tube having a sawtooth structure at the pipe end facing the ground.
  • a vacuum source outer tube having a sawtooth structure at the pipe end facing the ground.
  • an inner tube is rotatably mounted manually or by motor means, to which at least one outlet nozzle for a preferably liquid or gaseous material flow is provided, through which the earth material can be detached.
  • the loosened and detached earth material is disposed of appropriately by the vacuum applied along the outer tube.
  • US 3,554,293 a device for weeding and folding particular lawns, which provides a cutting tool at the end of a motor-driven shaft, which is surrounded by a can-like configured protective cover. By lowering the cutting tool relative to the protective sheath, a near-surface removal of material is realized.
  • DE 25 30 531 C2 shows a rotary drilling tool for earth drilling machines, in which the loosened by a mounted at the end of a rotatably mounted shaft drilling tool soil in a longitudinal axis of the drilling tool according to parent, bucket-shaped container is transferred. If the container is filled, the drilling tool closes off the otherwise downwardly open bucket, whereby the loosened soil can be removed in portions from the resulting wellbore.
  • the US 4,113,037 describes a stone drill with centering tip and Bohrstaubabsaugung.
  • the object is to provide a Erdbohrvorraum, which is easy to use and is especially suitable for private garden or construction needs and therefore should represent a cost-effective alternative to existing systems.
  • the auger is designed to allow a user to easily and quickly make holes with dimensions of up to one meter deep and a few decimeters in diameter.
  • a Erdbohrvorraum with a rotary drive connected to the rotary drive via a shaft drill head and a pipe; is formed such that the shaft extends at least partially axially along the tube with two tube ends, the first tube end is connectable to a vacuum source and the second tube end provides a tube opening through which the drill head at least partially projects beyond the tube that the drill head at least two with the Shaft associated web portions provides that are mounted with a radial extent on the shaft and only partially cover the tube opening in projection to the tube axis, that the web portions are each connected to an axially oriented surface portion to form a U-shape, wherein the axially oriented surface portions each have a Having radially outwardly oriented surface which occurs during rotation of the drill head in sliding contact with the tube inner wall or an inner wall of a coaxially connected to the second tube end sleeve, and in that the axially oriented surface sections are each connected to a leg which projects axially over the tube or the
  • legs are each radially outwardly inclined relative to the axially oriented surface portions such that the legs project radially beyond the outer diameter of the tube and / or the sleeve.
  • the drill head is referred to as a scratching bar, which has the protruding sections, such as web sections, axial surface sections and the legs.
  • FIG. 1 a shows a longitudinal section through a solution according trained Erdbohrerkopf.
  • FIG. 1b shows a longitudinal section through an alternative embodiment of an inventive Erdbohrerkopf, to which in FIG. 2 an axial plan view of the auger head is shown.
  • the earth boring head according to FIG. 1a differs from that according to FIG. 1b only in the training of the later described Kratzbügels 1, so that the further description refers to the entirety of the FIGS. 1a . b such as FIG. 2 ,
  • a scratching clip 1 is set in rapid rotation via a bending and torsion-elastic shaft 2. About a bushing 3 made of steel, which reduces wear, a suction pipe 4 is held centrally above the Kratzbügel 1. Due to the rotation, the elasticity and the unilateral striking of the scratching clamp 1 at the contact points 5 in the borehole 6, this is forced into a kind of tumbling or scraping movement 9. This results in new contact points 5 with the numbers a, b, c, d etc. ( Fig. 2 ), whereby the hole 6 is "knocked out" to a larger diameter than that of the Kratzbügels 1 and a uniform deep drilling is possible.
  • scavenging air 8 flows into the borehole 6 and transports the loosely ground soil through the suction pipe 4 to a excavation collector 10.
  • the scavenging air 8 is conveyed through the air in the borehole resulting negative pressure from the environment around the borehole drawn into this.
  • the scratching and striking motion also produces a bending vibration of the shaft 2 and a jarring of the suction pipe 4, which prevents sticky material (e.g., damp clay) from sticking to the inner walls of the suction pipe 2.
  • sticky material e.g., damp clay
  • the formation of the Kratzbügels 1 in the in FIG. 1 A illustrated embodiment is basically U-shaped.
  • the Kratzbügel 1 two with the shaft (2) connected to web portions (S), which are mounted with a radial extent on the shaft (2) and only partially cover the pipe opening in projection to the pipe axis.
  • the web portions (S) each pass, preferably integrally into an axially oriented surface portion (18a, 18b) whose radially outwardly oriented surface during rotation of the drill head in sliding contact with the tube inner wall or an inner wall of coaxially connected to the second tube end sleeve ( 3) occurs.
  • the axially oriented surface portions (18a, 18b) are axially extended so that they each, preferably in one piece in the tube (2) or the sleeve (3) axially superior legs (18c, 18d) pass or are connected thereto.
  • FIG. 3 a, b show a version for the drive of the shaft 2 and the connection to a flexible suction hose 12 to a Aushubsammler 10, the FIG. 11 is shown.
  • the shaft 2 is clamped along a flat 2 a via a clamping screw 13 in a clamping seat 14 with integrated flywheel 14 a.
  • a wire clamp 15 prevents friction by slipping out of the shaft 2 during fastening and aligns the flattening 2a to the screw 13.
  • the wave is at the in FIG. 3b illustrated embodiment via a clamping mechanism with two fastening screws 13 clamped in a clamping seat 14 with integrated flywheel 14a.
  • the clamping seat 14 is clamped by a hexagon 14 b fixed in an electric hand drill 11.
  • the drill 11 is decoupled from the rotational strokes of the Kratzbügels 1. This results in a relatively quiet running of the drill 11, which not only better handling, but also the protection of the drilling machine mechanism is used.
  • a bracket 17 is fixed, through which the manifold piece 16 is centered to the shaft 2.
  • the bracket 17 is formed so that a surface 17 a the clamping seat 14 with a defined distance 18 is parallel opposite.
  • the distance 18 allows the suction tube 4 together with elbow piece 16 to pull the clamping seat 14 and so release the bushing 3 relative to the scratching bar 1.
  • the released position is in Figure 5 shown.
  • a slip clutch 19 is attached to the connection between manifold piece 16 and intake manifold 4.
  • the slip clutch 19 is realized here by way of example via a rubber ring 19 a, which forms a frictional connection between the manifold piece 16 and the intake manifold 4.
  • the thus formed slip clutch also allows easy replacement of the suction tube 4, if this is worn.
  • the slip clutch 19 prevents an abrupt "eating" of the device.
  • the hand drill 11 can now be released relative to the bushing 3 by pulling back over the path length 18 of the suction tube 4 with manifold piece 16 of the scratcher 1 and thus the jammed stone can be removed easily and quickly.
  • the pushing back and releasing also allows for easier removal, since the suction tube 4 then tilts against the shaft 2.
  • the liner 3 Due to the closed round shape of the Kratzbügels 1 in the direction of the suction pipe 4, the liner 3 catches itself and centered so the suction tube 4 relative to the This scratching operation is also possible during drilling, so that scratching without simultaneous suction can be performed. This is for example advantageous if the hole is to be widened laterally.
  • Fig. 4 shows again the scratching clamp 1 with suction tube 4, according to the in Figure 1 b shown embodiment.
  • Decisive for the function is the combination of a jolting / beating scratching bracket 1 with the free-hold function of Absaugqueritese 7.
  • the legs 18c and 18d further protrude beyond the outer diameter 20 of the suction tube 4 and thus support the required Studttel- and impact function for breaking out of solid material.
  • In addition to supporting the protruding shaft 21 acts when keeping away from large stones from Absaugquerites 7 and facilitates immediate throwing away again.
  • Fig. 6 shows a variant of the Kratzbügels with soldered carbide cutting edges 22 to extend the life.
  • Fig. 7 shows a variant with 3 cutting which depending on the soil properties can prove advantageous. It should be noted that even more cutting are possible, which are not shown here.
  • Fig. 8 shows a variant of the Kratzbügels 1 as a cast construction with welded shaft 2. To recognize here is especially the back round shape which allows the catching of the bushing 3.
  • Fig. 9 shows a variant of the attachment of the bushing 3 on the intake manifold 4 with axial slots 25 and rivets.
  • Fig. 10 is a version with a remote socket with rivets shown.
  • Fig. 11 is a complete configuration with hand drill 11, excavator 10 and industrial vacuum cleaner 23 shown.
  • the industrial vacuum cleaner 23 sucks air from the excavation collector 10 via a coarse screen 10a.
  • the coarse sieve 10a prevents larger stones from getting into the filter bag of the industrial vacuum cleaner 23 and filling it quickly. By this separation, it is possible to deposit large amounts of excavation in Aushubsammler 10 without particulate matter enters the environment, which is retained in the filter bag.
  • a spring-loaded flap 24 can be mounted just behind the intake manifold 16 (see FIG Fig. 12 ), which opens when the air flow over the Kratzbügel 1 too low, ie the negative pressure in the suction hose 12 is too large.
  • air inlet openings 25 are mounted directly behind the (not shown here) scratching 1.
  • Fig. 13 shows a variant of a suction loader with hydraulically controlled suction pipe 26 for drilling larger holes from a truck or train car.
  • the suction tube 26 can not resonate, since it is rigidly attached to a hydraulic arm (not shown).
  • the vertical part 26a of the suction pipe is articulated via an elastic bellows 27.
