The utility model relates to the field of exploration sampling technology provides a kind of rotary
petroleum exploration core sampler to solve the problem such as the poor
cutting flexibility of traditional core sampler, clamping is not stable, sampling efficiency is low.The sampler moves seat by electric guide rail drive, drives pivot and multiple
cutting sheet flexible adjustment
cutting position, adapt to different size shape's core block;Rotary table is rotated by second
motor drive, realize multi-angle cutting, need not manual adjustment;Clamping
assembly adopts two clamps synchronous movement of bidirectional screw drive, rubber pad increases friction, prevents core block sliding;Knocking
assembly utilizes the power of first motor, moves up and down by
cam driving split cutter, knocks the core block after cutting and realizes separation, need not additional power source.The sampler improves cutting efficiency and
sample quality, reduces labour intensity, is applicable to the core sampling work in
petroleum exploration, meets the efficient, accurate, safe sampling demand.
