Zusammenfassung:As described in the description and depicted in the drawings, the present utility model application relates to a structural arrangement for devices for collecting superficial and deep samples of soft and very soft soils. More specifically, a sampling device is provided with a cutting-holding mechanism having the shape of a perfectly spherical cap with jaw-like blades connected thereto, designed to cut the sample at the end of the thrust-in process, in such a way that the sample is not pushed into the sampling device and is prevented from slipping, ensuring that the sample can be retrieved and minimising squashing effects both while the sampling device is thrust in and while the sample is retrieved. La présente demande de brevet de modèle d'utilité, conformément à la description et aux dessins annexes, concerne un agencement structural pour collecteurs d'échantillons superficiels et profonds de terrains mous et très mous. Plus particulièrement, un échantillonneur doté d'un mécanisme appelé coupe-support, en forme de calotte parfaitement sphérique, des lames formant mâchoires étant reliées à celui-ci, l'objectif étant, à la fin de l'introduction, de couper l'échantillon de manière à ne pas le pousser vers l'intérieur de l'échantillonneur, et d'empêcher que ce dernier ne glisse, garantissant ainsi sa récupération en réduisant au minimum les effets d'affaissement tant pendant l'introduction de l'échantillonneur que pendant la récupération de l'échantillon. Conforme descrito no relatório e conforme os desenhos anexos refere-se o presente pedido de patente de modelo de utilidade a uma disposição construtiva para coletores de amostras superficiais e profundas de solos moles e muito moles. Mais especificamente, um amostrador dotado de um mecanismo denominado corte-suporte, com formato de calota esférica perfeita, com lâminas conectadas como mandíbulas, que tem por objetivo, ao final da cravação, cortar a amostra de modo a não empurrá-la para dentro do amostrador, assim como impedir que a mesma escorregue, garantindo assim a sua recuperação, com minimização dos efeitos de amolgamento tanto durante a cravação do amostrador como durante a recuperação da amostra.
