2. A geodetic survey soil sampling apparatus as defined in claim 1, wherein: the top and the bottom of mount all are provided with the snap ring, and the snap ring fixed cover is located the urceolus outside.
3. A geodetic survey soil sampling apparatus as defined in claim 1, wherein: one side of the notch close to the first magnet is fixedly connected with a barrier strip.
4. A geodetic survey soil sampling apparatus as defined in claim 1, wherein: and a supporting spring is fixedly arranged between the compression ring and the supporting ring.
5. A method of taking earth using the earth-taking apparatus for geological survey of any one of claims 1 to 4, comprising the steps of:
the outer barrel is rotated to drill, when the outer barrel is drilled to a certain depth, one end of the limiting rod is moved out of the arc-shaped groove, the locking screw is rotated to fix the vertical shaft, when the mud guiding plate on the outer barrel is rotated to the second magnet, the mud guiding plate can be caused to deflect outwards through repulsive force between the first magnet and the second magnet, so that one end of the mud guiding plate, which is far away from the outer barrel, can be inserted into soil, then along with rotation of the outer barrel, the mud guiding plate can scrape and guide the soil down and between the outer barrel and the inner barrel, the soil entering between the inner barrel and the outer barrel can fall onto the pressing ring, so that the pressing ring moves downwards relative to the supporting ring, in the process, the pull rope is loosened, and when the limiting block on the supporting ring rotates to the limiting groove, the limiting block can pop out and be inserted into the limiting groove, so that the supporting ring can move upwards along the vertical direction relative to the rotating process of the inner barrel, and further the soil at the top of the pressing ring is driven to move upwards between the inner barrel and the outer barrel.
