Съемный пробоотборник относится к буровому оборудованию и предназначено для отбора керна малого диаметра. Цель изобретения - повышение надежности работы. Согласно изобретению керноотборник, содержащий ловильный захват, стопоры и полый ствол для приема керна, снабжен цанговым захватом, размещенным на полом стволе. Цанговый захват выполнен в виде подпружиненной цанги с фиксаторами, снабженными продольными выступами под продольные впадины колонковой трубы. При этом на наружной поверхности полого ствола выполнены продольные пазы, верхний участок которых имеет меньшую глубину. В этих пазах размещены фиксаторы.Removable sampler refers to the drilling equipment and is designed for the selection of cores of small diameter. The purpose of the invention is to increase reliability. According to the invention, the core sampler, comprising a catch grip, stoppers and a hollow barrel for receiving a core, is provided with a collet grip placed on the hollow barrel. Collet grip is made in the form of a spring-loaded collet with clamps provided with longitudinal projections under the longitudinal hollows of the core tube. At the same time, on the outer surface of the hollow shaft, longitudinal grooves are made, the upper portion of which has a smaller depth. In these grooves are placed the latches.
