Abstract
A process and device for extracting soil samples, wherein a core sample is extracted from the ground which is to be analysed and part of the soil is removed from the core for subsequent analysis or other after-treatment. The core sample is removed from the ground and enclosed in a encasing (32, 34) in which the core sample remains in the form and position it had in the ground prior to extraction. The required volumes of soil samples are removed via openings (46) in the encasing (32, 34) at pre-determined points, and collected for further treatment.
Description
- 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.
- In order to enable optimization of the yield of harvests within the agricultural industry, it is normal current practice to determine the soil's content of additives, such as fertilizers, by taking a number of soil samples from over a field and then to analyse them. Using the result of the analysis, it is possible to determine the type and quantity of additive to be put into the soil in order to improve the harvest yield. At the same time, the costs of fertilization and other soil treatments is reduced, as is also environmental damage, since no excess of additive is put into the soil. 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 results of sampling and the subsequent analysis are naturally dependent on the precision in the sampling process, i.e. the same volumes being taken at the same levels along the whole of the sampling line. To date, however, removing samples from the core has been carried out manually, which has not led to satisfactory reproducibility of the sampling process and has also resulted in a number of drawbacks in other respects. Manual removal of a required, suitable volume, for example about 50 cm3, of sample has been performed by employing a tool to remove scrapings from the various levels of the core sample, which method, besides the disadvantage of the sampling process being time-consuming, has not provided precision in the sampling process. Thus the volume of sample scrapings has varied considerably, due to the difficulty of estimating the correct volume and because accompanying lumps of earth, stones, etc., have increased the volume to an indeterminable extent. Neither has it been possible to define exactly the levels on which the samples have been removed. In order to reduce handling time, removal of samples has had to be performed at the same time as moving the drilling equipment between the drilling points in the field, although this is further detrimental to accuracy, since the work has had to be performed at the same time as the equipment has been moving over the uneven surface of the field. A further disadvantage is that the residue of the core sample, after sample extraction, has had to be removed from the drill steel before the next drilling begins. This manual removal of the remains of the previous core sample is also time-consuming and laborious.
- 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. These objects are achieved because the process and the device of the invention have been provided with the characteristics specified in the following patent claims.
- In the following, the invention will be described in greater detail, together with a preferred embodiment of a device for the performance of the method for taking samples. 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 atubular steering device 12, and twouprights 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 orscrew 18, which is described in greater detail below. Theuprights slide unit 20, which is movable in the longitudinal direction of theuprights drill holder 22. In thedrill holder 22, the rear, squared end-fitting 24 of thedrill 18, is pivoted in abearing 26, which also incorporates a power connection, such as a cog wheel or chain transmission from adrive motor 28, for example a hydraulic motor also fitted on thedrill holder 22. To theupper end 30 of theslide unit 20 is connected a control device (not illustrated), for example a hydraulic cylinder or motor, which during operation is disposed to move theslide unit 20 and therewith thedrill holder 22 and thedrill 18 fitted to it withdrive motor 28, in the longitudinal direction of theuprights slide unit 20 is shown in Its uppermost position, and when theslide unit 20 is moved downwardly in the Figure, thedrill 18 will pass through thesteering device 12 and the hole in the base plate and down into the ground below, while at the same time thedrill 18 is rotated via the drive motor in order to bore out a core sample. - It should be made clear that 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. In this connection, 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. Of course, tracked vehicles or the like may alternatively be used to carry the core sampling equipment illustrated in Figure 1. The
uprights 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. - After drilling, the
drill 18 is raised with the soil (core sample) remaining in the turns, with the aid of theslide unit 20 and the hydraulic device connected thereto. When. thedrill 18 passes throughsteering device 12 on theplate 10, the soil outside the turns of thedrill 18 will be scraped off, so that a core sample is obtained with the same outer diameter as the turn. - For the removal of the desired samples from the core sample extracted, an extraction mechanism is provided comprising two
tube halves axles 36, one of which is illustrated in Figure 1. Theaxles 36 are in turn are swivel-mounted inbrackets 38 secured to theuprights 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, thedrill 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. - To remove soil samples from the enclosed core sample, a number of
cutters 40, 42are used, in the case illustrated three pairs of cutters which are movable vertically, i.e. in the longitudinal direction of thedrill 18. In order for this movement along the core sample to be possible, the turns of thedrill 18 are provided with a number ofrecesses 44, which are located opposite each other along the longitudinal direction of. the drill. Theserecesses 44 have a width so much greater than thecutters recesses 44. Thecutters 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. - In order to enable the soil samples to be removed in the way described, the
recesses 44 in thedrill 18 must be located opposite the slots 46 intube half 34. This is achieved with the aid of avane 48 fitted to the upper squared end-fitting 24 of the drill, whichvane 48, when thedrill 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 thedrill 18. The prerequisite for this to function is that thevane 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 thedrive motor 28 for thedrill 18, when the drill is raised by the limit switch, to stop within the said angle range. When the tube halves 32, 34 are thereafter brought together, 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 thescrew 18 is defined exactly in relation to the slots 46 and thecutters drive motor 28 has been stopped, the pressure fluid circuit for thedrive motor 28 is suitably provided with a mechanical clutch or the like. - The vertical movement of the
cutters drill 18, is performed with the assistance of ahydraulic cylinder 52 withpiston rod 54, whichcylinder 52 is mounted in abracket 50 arranged ontube half 34. Thepiston rod 54 is, as is shown in greater detail in Figure 2, connected to abearing bracket 56 arranged on aplate 58 which bears the uppermost sampling mechanism. Theplate 58 is secured to asquare tube 60 which slides along guides 62 which in turn are secured totube half 34 by means of arms (Figure 1). At an equal distance from thesquare tube 60, twofurther clamp plates plates - Beneath the
plate 58 is pivot-mounted aclamp 69, which at its lower end bears thecutters tube half 34. Theclamp 69 is held in the position shown in Figure 3 by means of aspring 70 which is arranged between outer end of theplate 58 and the lower part of theclamp 69. The position of theclamp 69 in relation to theplate 58 can be adjusted using the adjustment screws 72, 74 shown in Figure 3. The sprung suspension allows theclamp 69 with thecutters spring 70 round the point of pivoting in the event that during upward movement of the mechanism along the slot 46, thecutters - 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, thehydraulic cylinder 52 is actuated such that thesquare tube 60 and the sampling mechanisms fitted thereon move upwardly along theguides 62 along thedrill 18. Theupper cutter 40 thereby cuts away an approximately 7 mm deep layer of soil which is carried via the upper side of thecutter 40 and achannel 76 of sheet steel or a similar material arranged at theend 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 thecutter 40 in the manner described. Thelower 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 thecutter 42 to, and falls down into a removable tray orbox 78 which is disposed below the end of thecutter 42, for example on aholder 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. - After removal of the soil samples, the
tube halves hydraulic cylinder 52 returns the sampling mechanisms to the lower position also illustrated in Figure 1. While the wagon or truck carrying the drilling equipment is being moved to the next sampling location, the residues of the core sample are removed, which is suitably performed by means of an in itself knownpercussion device 82, which is illustrated diagrammatically above theupper end 24 of thedrill 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. - In the embodiment shown in Figure 4 the parts corresponding to the embodiment in Figure 3 has the addition of an "a". The difference between Figures 3 and 4 lies in the fact that the
lower cutter 42a is swingable journalled on thepin 180. Aspring 182 biases thecutter 42a into the position shown with unbroken lines in Figure 4. When thesquare tube 60 and the sampling mechanism fitted thereon are in the lowest position and the tube halves 32,34 are closed around thedrill 18, thecutter 42 will be swinged towards the position engaging the cutter 40a, as shown with dotted lines in Figure 4, due to contacting the lower edge of the slot in the tube half. Soil cannot then enter the space between the cutters40a and 42a so that contaminted soil will not fall into thebox 78a. When the sampling mechanisms are moved upwardly thecutter 42a is forced into the position shown by unbroken lines in Figure 4 byspring 182 and will cut uncontaminated soil from a position deeper in the soil column. Soil from the surface which possible may contain impurities will thus not be cut out. - From the above, it is evident that a sampling device has been obtained which offers a number of advantages. The enclosing of the core sample during extraction provides the maximum guarantee that the sample will reproduce exactly the conditions at the corresponding location in the ground. As the samples are taken in a vertical direction, a representative sample is obtained for the whole level despite the smallness of the sample volume, while sampling at several strictly defined levels allows the possibility of separate analysis of the samples. The sample volume extracted on each occasion, approximately 20 cm3, which is determined by the dimensions of the
cutter 42 is very precise, since no lumps of earth or the like can affect the sampling process, which is thus uninfluenced by the nature of the ground. - Even if the device has been described as being powered by pressure fluid, such as hydraulic fluid, it is clear that other sources of power are conceivable, also including, for example, manual operation of the mechanisms. It is thus clear that the illustrated and described embodiment is only an example of application of the invention and that this can be modified and varied within the scope of the following patent claims.
