Definitions

  • This invention relates to a process for taking soil samples, wherein a core sample is taken from the ground which is to be analysed, and a section of the soil is removed from the core for subsequent analysis or other after-treatment.
  • the invention also relates to a device for the performance of this process.
  • Sampling is normally carried out along at least one sampling line over the field, whereby, using a drill steel, screw conveyor or the like, core samples are extracted from a number of points, for example 20, along the sampling line, and, from the core sample extracted in this way, a required sample volume is removed from a number of points corresponding to various soil depths.
  • the main object of the invention is therefore to provide a process and device for taking of core samples, wherein these disadvantages are eliminated, so that it is possible for the rate of sampling to be substantially increased and precision improved, whereby the reliability of the test result obtained is improved considerably.
  • Figure 1 is a perspective view of the essential part of the core sampling device, and the parts contained therein.
  • Figure 2 is a perspective view of the rear of a section of an encasing shown in Figure 1, which is used to enclose the core sample extracted, together with the sampling mechanism arranged on the reverse of the encasing.
  • Figure 3 shows a longitudinal section through the drill steel enclosed by the encasing, together with one of the sampling mechanisms arranged on the encasing.
  • Figure 4 shows a section through another embodiment.
  • the core sampling device illustrated in Figure 1, comprises a base plate 10, which bears a tubular steering device 12, and two uprights 14 and 16.
  • the steering device, 12, is arranged above a circular hole (not illustrated) in the base plate 10, and the inner diameter of the steering device and the hole corresponds to the outer diameter of the core sampling device's drill or screw 18, which is described in greater detail below.
  • the uprights 14, 16 act as steering guides for a slide unit 20, which is movable in the longitudinal direction of the uprights 14, 16 , and which in turn bears a drill holder 22.
  • the rear, squared end-fitting 24 of the drill 18, is pivoted in a bearing 26, which also incorporates a power connection, such as a cog wheel or chain transmission from a drive motor 28, for example a hydraulic motor also fitted on the drill holder 22.
  • a control device for example a hydraulic cylinder or motor, which during operation is disposed to move the slide unit 20 and therewith the drill holder 22 and the drill 18 fitted to it with drive motor 28, in the longitudinal direction of the uprights 14, 16 for raising and lowering of the drill.
  • the slide unit 20 is shown in Its uppermost position, and when the slide unit 20 is moved downwardly in the Figure, the drill 18 will pass through the steering device 12 and the hole in the base plate and down into the ground below, while at the same time the drill 18 is rotated via the drive motor in order to bore out a core sample.
  • the drilling device shown is suitably arranged on a means of transport, such as a wagon or powered vehicle so as to be capable of being easily moved over the field in which the samples are to be taken.
  • the vehicle should be of the type with a low pressure of weight against the ground, which is normally achieved by the vehicle having several wheels, for example six, eight or more having a broad area of contact with the ground.
  • tracked vehicles or the like may alternatively be used to carry the core sampling equipment illustrated in Figure 1.
  • the uprights 14, 16 and the drill 18 are of suitable lengths for the extraction of a core sample from the required depth, for example a depth of approximately 1 metre in the field.
  • the drill 18 After drilling, the drill 18 is raised with the soil (core sample) remaining in the turns, with the aid of the slide unit 20 and the hydraulic device connected thereto. When. the drill 18 passes through steering device 12 on the plate 10, the soil outside the turns of the drill 18 will be scraped off, so that a core sample is obtained with the same outer diameter as the turn.
  • an extraction mechanism comprising two tube halves 32, 34 which are secured to axles 36, one of which is illustrated in Figure 1.
  • the axles 36 are in turn are swivel-mounted in brackets 38 secured to the uprights 14, 16 on the drilling device.
  • the tube halves 32, 34 can be swivelled by means of a control mechanism, not illustrated in greater detail, from the open position shown in Figure 1 to a position in which they enclose the drill 18 and the core sample extracted (see Figure 3).
  • the tube halves 32, 34 thus enclose, as shown in Figure 3, in their swivelled-together position, the drill 18 and the core sample with extremely little play. In this way, the core sample extracted will be maintained in the dimensions and form which it had in the ground prior to extraction, and samples can be bored out without any soil falling off or changing position.
  • a number of cutters 40, 42 are used, in the case illustrated three pairs of cutters which are movable vertically, i.e. in the longitudinal direction of the drill 18.
  • the turns of the drill 18 are provided with a number of recesses 44, which are located opposite each other along the longitudinal direction of. the drill.
  • These recesses 44 have a width so much greater than the cutters 40, 42 that the cutters are able to pass unimpeded through the recesses 44.
  • the cutters 40, 42 enter through slots 46 in the tube half 34 on which the extraction mechanism is fitted, and are moved along the slot 46 by a mechanism which is described in greater detail below.
  • the recesses 44 in the drill 18 must be located opposite the slots 46 in tube half 34. This is achieved with the aid of a vane 48 fitted to the upper squared end-fitting 24 of the drill, which vane 48, when the drill 18 is stationary, is arranged to rest in the plane of the surface of division between the tube halves 32, 34, when the latter are swivelled into the position enclosing the drill 18.
  • the vane 48 when rotation of the drill steel is stopped, comes to rest at some point within a total angle of about 120° around this plane, which prerequisite is achieved by the means of causing the drive motor 28 for the drill 18, when the drill is raised by the limit switch, to stop within the said angle range.
  • the vane will come into contact with the edge of one of the tube halves and will be brought into the position described above in the surface of division between the tube halves, by which means the position of the screw 18 is defined exactly in relation to the slots 46 and the cutters 40, 42.
  • the position is also secured inasmuch as the squared end-fitting 24 is fixed into the corresponding recess in the tube halves.
  • the pressure fluid circuit for the drive motor 28 is suitably provided with a mechanical clutch or the like.
  • the vertical movement of the cutters 40, 42, i.e. along the drill 18, is performed with the assistance of a hydraulic cylinder 52 with piston rod 54, which cylinder 52 is mounted in a bracket 50 arranged on tube half 34.
  • the piston rod 54 is, as is shown in greater detail in Figure 2, connected to a bearing bracket 56 arranged on a plate 58 which bears the uppermost sampling mechanism.
  • the plate 58 is secured to a square tube 60 which slides along guides 62 which in turn are secured to tube half 34 by means of arms ( Figure 1).
  • two further clamp plates 66, 68 are fitted for two further sampling mechanisms. Since all three sampling mechanisms on the plates 58, 66, 68 are identical, only one of them will be described in the following in relation to Figures 2 and 3.
  • a clamp 69 Beneath the plate 58 is pivot-mounted a clamp 69, which at its lower end bears the cutters 40, 42 which enter through the slot 46 the tube half 34.
  • the clamp 69 is held in the position shown in Figure 3 by means of a spring 70 which is arranged between outer end of the plate 58 and the lower part of the clamp 69.
  • the position of the clamp 69 in relation to the plate 58 can be adjusted using the adjustment screws 72, 74 shown in Figure 3.
  • the sprung suspension allows the clamp 69 with the cutters 40, 42 to give way to the force from the spring 70 round the point of pivoting in the event that during upward movement of the mechanism along the slot 46, the cutters 40, 42 should come into contact with a stone or other hard object in the core sample.
  • the sampling mechanism described functions in the following way: when the tube halves 32, 34 have been closed around the drill 18 and the core sample found in the turns of the drill, the hydraulic cylinder 52 is actuated such that the square tube 60 and the sampling mechanisms fitted thereon move upwardly along the guides 62 along the drill 18.
  • the upper cutter 40 thereby cuts away an approximately 7 mm deep layer of soil which is carried via the upper side of the cutter 40 and a channel 76 of sheet steel or a similar material arranged at the end 40 of the drill, to a position outside the mechanism and falls away.
  • This layer of soil which is on the surface of the core sample and which contains impurities and surface soil (top soil), is not required in the sample, and thus is removed with the cutter 40 in the manner described.
  • the lower cutter 42 cuts a further depth of 15 mm and a length of 250 mm, removing thereby a soil sample, which is carried along the upper side of the cutter 42 to, and falls down into a removable tray or box 78 which is disposed below the end of the cutter 42, for example on a holder 80.
  • the 3 sampling mechanisms shown are suitably arranged such that the cutters remove samples from the core sample within areas on different depths in the soil.
  • the tube halves 32, 34 are swivelled apart to the position illustrated in Figure 1 and the hydraulic cylinder 52 returns the sampling mechanisms to the lower position also illustrated in Figure 1.
  • the residues of the core sample are removed, which is suitably performed by means of an in itself known percussion device 82, which is illustrated diagrammatically above the upper end 24 of the drill 18, and whose impact is applied axially on the drill, by which means any residual core sample is effectively removed from the turn.
  • the device may be replaced by other suitable mechanisms.
