SOIL EXCAVATION SAMPLING DEVICE AND SOIL EXCAVATION SAMPLING METHOD
To provide a soil excavation sampling device capable of being reduced in weight and collecting a soil sample at a predetermined depth while saving energy.SOLUTION: A soil excavation sampling device of the present invention is a device that inserts a rod into the ground and collects a soil sample at a predetermined depth. The tip of the rod has a helical cutting edge and an escape groove formed on its outer circumference, and has a sample chamber for containing a soil sample therein and a driving device behind the sample chamber. The sample chamber has a sampling port at the tip of the rod. Furthermore, a small drill is provided that can move forward and backward from the tip of the rod. The small drill advances and retreats by the driving device to open and close the sampling port, so that there is no danger that soil samples at the other depth than the predetermined depth are mixed, and the weight of the device can be reduced, and the soil samples can be collected while saving energy.SELECTED DRAWING: Figure 3
【課題】軽量化が可能で、かつ省エネルギーで所定深度の土試料を採取できる土壌掘削サンプリング装置を提供する。【解決手段】本発明の土壌掘削サンプリング装置は、地中にロッドを挿入し、所定深度の土試料を採取する装置である。そして、上記ロッドの先端部は、外周に螺旋状の切り刃と逃げ溝とが形成され、その内部に土試料を収容する試料室と、該試料室の後方に駆動装置とを備え、上記試料室がロッドの先端に採取口を有するものであり、さらに、上記ロッドの先端から進退可能に設けられた小ドリルを備え、上記小ドリルが、上記駆動装置によって進退し、上記採取口を開閉することとしており、所定深度以外の土試料が混入する恐れがなく、軽量化が可能でかつ省エネルギーで土試料を採取できる。【選択図】図３
