Drilling fluid sampling device

Abstract

The utility model discloses a drilling fluid sampling device, which belongs to the technical field of sampling equipment and comprises a bottom plate, the top of the bottom plate is fixedly connected with a storage box, one side of the storage box is fixedly connected with a sampling pump, a liquid inlet of the sampling pump is fixedly connected with a sampling pipe, and the side wall of the sampling pipe is fixedly connected with a plurality of branch pipes. The branch pipes are distributed at different heights, electromagnetic valves are arranged in the branch pipes, a stirring mechanism is arranged in the storage box, the stirring mechanism comprises a rotating shaft, the rotating shaft is movably connected with multiple sets of stirring blades arranged in the circumferential direction through elastic pieces, and a guide assembly is arranged between the stirring blades and the inner wall of the storage box. The drilling fluid sampling device has the beneficial effects that a plurality of branch pipes are arranged on the sampling pipe, opening and closing of the branch pipes are controlled through electromagnetic valves, the branch pipes are distributed at different heights and positions of a pipeline, drilling fluid samples at different parts can be collected, then drilling fluid is mixed and stirred through a stirring mechanism, and a representative comprehensive sample is formed; the representativeness of the sample is improved.
