Abstract A latch head assembly for a core receiving apparatus including a core tube assembly and a retrieving head is provided. The latch head assembly includes a support, a first coupling for releasably engaging the retrieving device coupled to a first end of the support, and a second coupling for releasably engaging the core tube assembly coupled to a second end of the support. A core receiving apparatus including the latch head assembly is also provided. A method for inserting and retrieving the core receiving apparatus into and from a drill string is also provided. La présente invention concerne un ensemble tête de blocage pour un appareil de réception de carotte comprenant un ensemble tube carottier et une tête de récupération. L'ensemble tête de blocage comprend un support, un premier couplage pour une mise en prise de manière libérable du dispositif de récupération couplé à une première extrémité du support, et un second couplage pour une mise en prise de manière libérable de l'ensemble tube carottier couplé à une seconde extrémité du support. Un appareil de réception de carotte comprenant l'ensemble tête de blocage est également décrit. La présente invention concerne en outre un procédé permettant d'insérer et de récupérer l'appareil de réception de carotte dans et à partir d'un train de forage.
