A VERTICAL TYPE SOIL SAMPLER

摘要

PURPOSE: A vertical soil sampler is provided to accurately and effectively analyze various data about the physical and chemical properties and structures of soil by sampling soil samples in original structures of the soil without distortion because the soil samples are not compressed and twisted. CONSTITUTION: A vertical soil sampler comprises a hollow outer tube, a hollow inner tube(100), and hollow soil sampling tube. The outer tube comprises a rotary blade(210) formed in the outer circumference thereof. The inner tube is located inside the outer tube and is connected to the outer tube by bearings(110). The inner tube receives only vertical force of the outer tube because the inner tube is not rotated even through the outer tube rotates. The soil sampling tube is inserted inside the inner tube and collects the soil. The soil sampling tube is longer than the inner tube and has a through-hole for fitting a bar at the top thereof so that the soil sampling pipe can be removed from the inner tube.
