Abstract

Bei einem Spiralbohrer (60) zur Entnahme von Bodenproben, insbesondere aus landwirtschaftlichen Nutzflächen besteht dieser aus einer im wesentlichen zylindrischen Bohrstange (62) mit einem darauf befindlichen im wesentlichen flachen Spiralband (64). Das Spiralband (64) verjüngt sich von außen zur Bohrstange (62) hin. Vorteilhaft ist es, wenn sich das Spiralband (64) von außen zur Bohrstange (64) hin mit einem Winken von 2° bis 5°, vorzugsweise 2,5° bis 3,5° verjüngt.

Figure 00000001
In the case of a twist drill (60) for taking soil samples, in particular from agricultural areas, it consists of an essentially cylindrical boring bar (62) with an essentially flat spiral band (64) thereon. The spiral band (64) tapers from the outside towards the boring bar (62). It is advantageous if the spiral band (64) tapers from the outside towards the boring bar (64) with an angle of 2 ° to 5 °, preferably 2.5 ° to 3.5 °.
