Definitions

  • the invention relates to a drill with which Soil samples with a high rate of succession to the soil, especially the soil of agricultural Usable areas can be removed.
  • WO 96/01360 proposes a device with which Withdrawals around a vehicle at different locations can be done without moving through the vehicle loses time.
  • the removal device according to WO 96/01360 also has the considerable disadvantage on that a change in the insertion of the drill in the Floor is possible.
  • the device according to WO 96/01360 the risk of losses in the upper layer the floor profile, especially the top 1-3 cm. This is in sandy soils with the device suggested there hardly to avoid.
  • twist drills are known in which a drill bit lowered to a certain depth and a soil sample during the subsequent lifting takes.
  • a drill bit lowered to a certain depth and a soil sample during the subsequent lifting takes.
  • Such a device is for example from the DE 38 39 003 A1 known. But especially one Device is with the disadvantages described above afflicted that a change can take place and that a loss in the top layer of the soil profile is possible.
  • Desirable for a soil sampling device which Working at a high rate is also a control whether the desired drilling depth has been reached, as a too shallow sampling usually too high Fakes nutrient supplies.
  • the above object of the invention is achieved by a Drill solved, as defined in claim 1.
  • the measures of the invention are first of all Consequence that the material when sampling in the drill something compacted and so the material is prevented detached from the drill prematurely when pulling it out becomes.
  • the soil sampling device 100 on one side arranged which in Figure 3 again in enlarged Representation is shown.
  • the vehicle which in the Embodiment as an all-terrain vehicle with four Wheels 220 and an attached cab 210 built is still accessible to the operator and operator the on-board computer and the entire operating device (not shown). There is a in the cab Foot lever with which the driving operation is locked and the Soil sampling device 100 is activated.
  • the soil sampling device 100 has in its lower area on a twist drill 60, which from the engine 10 is driven via a threaded spindle 20.
  • the engine 10 is over a guide column 30 in the vertical direction guided so that it - together with the threaded spindle - with the twist drill is moved up and down together.
  • the up and down movement is by a Threaded spindle 20 supporting guide nut 40 supports and by one located outside the guide column Excavation cylinder 50 directed vertically.
  • Soil sampling device 100 is like this set up that - in addition to the basic position - at least the following workflows can be carried out: First the twist drill is carried out during the actual drilling process a rotation - in the embodiment seen from above in Clockwise - while lowering into the ground performed, the lowering force primarily from the System of motor 10, threaded spindle 20 described above and lead nut 30 is exercised. The second process is a Lifting the twist drill 60 from the ground, being in the Spirals the soil sample is pulled up.
  • the Twist drill 60 holding cutter 70 along the Twist drill 60 lowers down and the soil sample clears out the cavity between the endless spiral band.
  • a container 80 for the sample material can be viewed from the side be pushed under the twist drill 60 and that Collect sample material while it is being cleared falls down.
  • the last process is then a Procedure in the basic position possible, the container 80 again in a basic position laterally offset opposite the drill bit 60 is driven.
  • the position of the Container 80 is over sensors - in the embodiment via magnetic sensors - monitored.
  • Positions of the drilling device is in the embodiment determined by magnetic switches that have a Control device passed on to the on-board computer become.
  • the position of the magnetic switches is related to the height can be moved so that - up to a maximum depth the soil sampling process - basically every depth can be specified, e.g. for a particular Partial area always reaches a predetermined drilling depth becomes.
  • Soil samples mixed together and analyzed together become. So the container 80 for the soil samples does not have to be emptied for each soil sample taken, but only when all soil samples for this subarea are removed.
  • the one attached to the vehicle 200 Soil sampling device 100 can - after that Vehicle 200 takes its position for taking the soil sample has taken - lowered as a whole and with constant pressure on the ground.
  • the Position of the vehicle 200 and thus the Soil sampling device 100 is provided by an on board located navigation system and with the predetermined target data for the corresponding section compared.
  • the navigation system comes in Embodiment a GPS receiver used, the Accuracy through the use of another transmitter for correction data is improved (differential GPS).
  • All functions of the soil sampling device 100 are instructed by the on-board computer and one Control device controlled.
  • the parameters for Withdrawals are recorded in a control facility and transmitted to the on-board computer.
  • the one in the embodiment for soil sampling used drill bit 60 has properties that make him particularly suitable for this task.
  • a substantially smooth boring bar 62 is a flat spiral band 54 attached. But it got through extensive tests as particularly suitable exposed when this spiral band 64 is from the outside inwards with an angle of 2 ° to 4 °, preferably of Tapered 3 ° and in a way a cavity trains the sample material during the drilling process compacted and not during the lifting process of the twist drill before the material escapes through the clearer 70 is cleared and collected in container 80.
  • the in FIG. 15 and FIG. 16 clearer 70 is out Vulculan made.
  • the described arrangement of the Twist drill 60 in cooperation with the remover 70 has proved to be particularly advantageous.
  • the spiral band is 3 mm outside thick.
  • the boring bar has a diameter of 10 mm (Inner diameter of the drill) and the drill itself has an outer diameter of 19 mm.
  • the slope of the Spiral tape is 15 mm / turn, the pitch angle is 12 °.
  • the device shown in Figures 3 to 12 is provide a covering on all sides that forms a closed housing so that the Soil sampling device 100 itself is protected.
  • the cladding can be used for maintenance or illustrative purposes be removed.
  • the sequence of sampling with the invention is preferably carried out as follows:
  • the vehicle 200 is driven into place, at which the sampling device 100 is above the solo position is available for removal.
  • the vehicle 200 is stopped and the driver operates the foot pedal to activate the Sampling device 100.
  • This process is coupled with the brake, so that the vehicle 200 with activated Sampling device 100 can not be moved.
  • the Pressing the foot lever triggers a signal to release the Sampling, which is transmitted to the on-board computer.
  • the sampling device 100 moves from the Transport position in the working position - it will leaning on the ground with constant pressure - while the software of the on-board computer checks the Position of the vehicle 200, whether the minimum distance to the Area borders and previous positions of Sampling points are observed. The distances are in On-board computer can be parameterized.
  • the on-board computer sends one Signal of the target sampling depth to the drilling machine.
  • the Sampling depth is area-related and is carried out with the Transfer order data to the sampling vehicles.
  • the drilling device 100 begins the drilling process; the drill 60 is rotated into the ground in a spiral. During the entire drilling process is via a 'dead man's switch' ensures that vehicle 200 is moving is prevented.
  • the drill 100 sends the signal to 'drill up' as well as the test depth achieved on the on-board computer (on-board PC). This saves the position and for each 'hole' the sample depth.
  • the drill 60 of the drill is until the sensor reaches the end position signals, at the same time the drilling rig is 100 in Transport position driven so that during the Emptying process of the drill 60 is already the next one Sampling point can be controlled.
  • the vehicle 200 is set in motion by a foot contact switch. If the drill 60 is in the end position, the Sampling container 80 from the basic to the Emptied position driven. This process is also about Controlled sensors so that the optimal position of the Sampling container 80 is ensured. After emptying of the drill, the sampling container 80 into the Home position retracted.
  • each sub-area to be sampled there must be one certain number of target punctures per mixed sample become.
  • the information about the target stitch number is also included in the order data and is parameterizable. Only when the minimum number of stitches is reached the sampling container 80 can be emptied. At the The display of the on-board computer is the current one Number of punctures is displayed in the area currently being processed. After reaching half of the target stitch number, the Sampling label printing allowed.
