GERAET ZUR ENTNAHME VON BODENPROBEN

摘要

A device for taking a soil sample can be used both in cooperation with a handling device and as a hand boring rod. The device has a probe (1) with a cylindrical tubular casing (9) the head end of which has a handling device (28) that closes the end of the probe (1) nearer the head of the tubular casing and that can be proviced with a percussion accessory (36) or with a connecting device to the handling device. The tubular casing (9) delimits a receiving space for the sample (7) or for a container for receiving the sample. The receiving space opens into the through channel of a tip (10) arranged at the foot end of the tubular casing, and a nonreturn device consisting of at least two spring wires (23) projects into the receiving space. To reduce the forces required for insertion and withdrawal, the tip (10) can be designed as a double conical frustum and have a casing section (17) which projects radially above the tubular casing (9).
