Изобретение относ тс к горному делу.The invention relates to mining.

Известны устройства дл отбора образцов порода, содернащие корпус, рабочий орган с приводным механизмом н пробопрйемник ClJ, 23.Known devices for sampling rock, containing the body, the working body with a drive mechanism and sampler ClJ, 23.

Цель изобретени - повь ение эффективности отбора образцов и упрощение конструкции.Поставленна цель достигаетс тем, iTo предлагаемое устройство :с абжено магазином сраэделительны «а маркирую1ЛИМИ элементами :И тод.кателем этих элементов .The purpose of the invention is to increase the efficiency of sampling and simplify the design. The goal is achieved by the iTo proposed device: with the abbreviated magazine, the labeling 1LIM elements: And the current.datel of these elements.

На фиг.1 изображено предлагаемое устройство, поселение,п|эд отборе прог бы; на фиг.2 - то же, .;pS3jD;ene i M проб породы. . Figure 1 shows the proposed device, the settlement, p | ed selection of the program would; figure 2 - the same.; pS3jD; ene i M rock samples. .

Устройство имеет корпус .1г;;3акреп- .. ленную внутри корпуса режущую: голОйку 2 с рабочим органом 3. В ::из дакйо.:час:Т- Ь корпуса режущей головки встроен iJiaaiie литель, который содержит заполнейный разделительными маркирующими элеме та Ми (шаракш) 4 магазин 5 с удерживаю&о(м озары порогом 6 и выходным каналом 7/ и толкатель В. Керноприемник закреплен на ос х 9 и состоит из верхней поворотной части 10 с клином 11, котора т гами 12 св зана шарнирно с корпусом разделител (режущей головки) и служит дл приема вырезанного образца 13 из нижней части 14 керноприемника дл его складировани . Устройство работает следующим образомThe device has a body .1 g ;; 3 fixed inside the body of the cutting: head 2 with the working body 3. B :: from the duqo.: Hour: The body of the cutting head has a built-in iJiaaiie separator containing Mi (sharaksh) 4 magazine 5 s hold & o (m lumen with threshold 6 and output channel 7 / and pusher B. The core receiver is fixed on axis 9 and consists of an upper swivel part 10 with a wedge 11, which is pivotally connected 12 to 12 the separator (cutting head) and serves to receive the cut out sample 13 from the bottom 14 core a receiver for it store the same. The apparatus operates as follows:

После спуска к заданному интервалу скважины потоком жидкости, подаваемым по трубам с поверхности буровыми насосами , приводитс в действие приводной механизм, выдвигающий в рабочее положение (фиГ:..1.):,рабочий орган 3 и поворотную част)Е 10 керноприемника. Подъемом керйоотёорника, закрепленного на бурильных трубах, вырезаетс образец породы 13/ который отламываетс клином 11, перемещаетс ho внутреннему каналу пробоприемника, и складируетс в виде ориемтированйОго .столбика, состо щего й отдельных кусксз породычAfter descending to a predetermined interval of the well, the flow of fluid supplied through pipes from the surface by the drilling pumps triggers a drive mechanism that pushes into working position (fig: 1.) :, working body 3 and turning part) E 10 core receiver. A rock sample 13 is cut out by lifting the corepipe attached to the drill pipe, which is broken off by a wedge 11, is moved to the inner channel of the sampler, and stored in the form of a reference column consisting of individual pieces of rock.

Claims

At the end of the sampling period, the supply of washing liquid is stopped at the nominal interval. The separator together with the rotary part npo6onpHeMHrfi a under the action of a spring-loaded lever-piston mechanism (not shown in the drawings) enters the coring unit housing. At the same time, the internal cavity of the rotary part 10 of the core receiver occupies a position directly below the output channel 7 of the separator, and the pusher 8 pushes the cavities of the separator into the core receiver ball 4 (see figure 2), which separates the early sample from the next one. For the purpose of defining the selection intervals, the balls can be labeled with a serial number. Thus, the separation of samples by sampling intervals is carried out automatically every time the washing liquid supply is drawn, after which the device is ready to be transported to the surface or to be installed in a subsequent interval. The use of the proposed design of the device for sampling provides, when compared with the existing structures, the ability to obtain a larger number of samples for each well ia well and separate them by interval 1M of sampling; and simplify the design of the device. Claims An apparatus for sampling rocks, comprising a housing, an actuator with a drive mechanism and a sampling receiver, characterized in that, with a greater efficiency of testing and simplifying the design, it is equipped with a magazine with separating marking elements and a pusher of these elements.
