Bucket type molten steel sampler capable of being quickly demoulded

The utility model relates to the technical field of steelmaking equipment, and discloses a quick demoulding pail type molten steel sampler which comprises a sampling barrel, a sampling rod is fixedly assembled on the outer edge of the sampling barrel, a molten steel groove is formed in the sampling barrel, a barrel cover is arranged on the top of the sampling barrel, an axial through hole is formed in the bottom of the sampling barrel, and a through hole is formed in the bottom of the sampling barrel. And a demolding rod is arranged on the inner wall of the axial through hole. The included angle between the sampling rod and the sampling barrel is set to be 35 degrees, so that the sampling barrel can be conveniently stretched into a molten steel tank by an extraction worker, the sampling barrel can be conveniently taken out, the sampling barrel and molten steel are on the same horizontal line during taking, the molten steel in the sampling barrel cannot flow out, and the problem that the sampling rod on a trad
