The invention concerns a device for taking samples in a material of granular or powdery composition, comprising a rod (12) at one end of which is mounted a hand grip (10) for rotating the wheel and at the other end of which is a driving head (13). Said device is characterised in that the head (13) is mounted symmetrically on the rod (12) and comprises lower and lateral parts having a profiled shape, the rod (12) having a specific form for scraping the material over its entire length and the head (13) having a cross-section smaller, equal or larger than the cross-section of the rod (12), in specific proportions based on the type and/or moisture content of the material to be sampled.

La présente invention concerne un dispositif de prélèvement d'échantillons dans un matériau de constitution granuleuse ou pulvérulente, comprenant une tige (12) à une extrémité de laquelle est monté un volant (10) destiné à faire tourner l'outil et à l'autre extrémité de laquelle se trouve une tête (13) d'enfoncement. Ce dispositif se caractérise en ce que la tête (13) est montée symétriquement sur la tige (12) et comprend des parties inférieures et latérales avant une forme profilée, la tige (12) ayant une forme déterminée pour effectuer un raclement du matériau sur toute la profondeur et la tête (13) ayant une section transversale inférieure, égale ou supérieure à la section transversale de la tige (12), dans des proportions déterminées en fonction de la nature et/ou de l'humidité du matériau à prélever.
