Telescopic automatic ore pulp sampling device

The utility model discloses a telescopic automatic ore pulp sampling device which is characterized in that a fixed sleeve is downwards connected from a main ore pulp pipeline, a telescopic sampling pipe is arranged in the fixed sleeve, a normally closed sleeve cover is arranged at one end, butted with the main ore pulp pipeline, of the fixed sleeve, and the sleeve cover seals the fixed sleeve; when the sampling pipe extends out of the fixed sleeve, the sleeve cover is jacked open for sampling; the tail end of the sampling pipe is connected with a discharge pipe, and is connected with a samplecollection barrel or an analysis system through the discharge pipe. A plurality of sampling holes with smaller diameters are formed in the sampling pipe from top to bottom, so that a small amount of representative ore pulp with different densities and different particle sizes in the ore pulp main pipeline can be collected, and the ore pulp flowing in from the upper part can be prevented from impacting the inner wall of th
