SOIL SAMPLING DEVICE
PROBLEM TO BE SOLVED: To satisfy a requirement that there has been requested a soil sampling device which can remarkably prevent the intrusion of soil into a clearance compared with a conventional fixed-type soil sampling device.SOLUTION: This soil sampling device comprises a cylindrical outer tube and an inner tube which is rotatably inserted into the outer tube. In the outer tube, two or more vertically-oblong openings are formed at a position in which the openings become rotationally symmetric in a cross section view orthogonal to an axial direction, scraping members are arranged at vertical edge parts of the openings, and in a position in which the scraping members become rotationally symmetric in a cross section view orthogonal to the axial direction, and in the inner tube, two or more soil accommodation parts which communicate with the openings, and have openings having magnitudes equal to or larger than the openings are arranged in a position in which the soil accommodation parts become rotationally symmetric in a cross section view orthogonal to the axial direction.SELECTED DRAWING: Figure 1
【課題】従前の固定式の土壌サンプリング装置に比べて、土壌を隙間に混入することを飛躍的に防止することができる土壌サンプリング装置が望まれていた。【解決手段】本発明に係る土壌サンプリング装置は、円筒形の外管と、外管内に回転自在に挿入される内管を備え、外管には、縦長の開口が軸方向に直交する断面視において回転対称となる位置に２つ以上設けられているとともに、掻き取り部材が、開口の長手方向の縁部でかつ軸方向に直交する断面視において回転対称となる位置に設けられ、内管には、開口と連通し、かつ開口と同等以上の大きさの開口を有する土壌収納部が、軸方向に直交する断面視において回転対称となる位置に２つ以上設けられていることを特徴とする。【選択図】図１
