Sampling device for oily sludge detection sample

The utility model discloses an oily sludge detection sample sampling device which comprises a sampling pipe with a hollow structure, a first adjusting handle, a material pushing pipe, a sealing assembly, a second adjusting handle, a flushing pipe, a connecting assembly and a sealing cover, according to the sampling device for the oil-containing sludge detection sample, the sampling pipe is inserted into sludge to sample the sludge, the sampled sludge is stored in the inner cavity of the sampling pipe, the material pushing pipe moves upwards in the sampling pipe due to the pressure of the sludge, and when the sludge sample in the sampling pipe needs to be discharged, the material pushing pipe can push the material pushing pipe to move upwards. A sludge sample in the inner cavity of the sampling pipe can be pushed and discharged by a material pushing pipe only by pressing a second adjusting handle, and after discharging is completed, flushing liquid is injected into the upper end face of a flushing pipe to flus
