Simple sampling device for large-container raw wine

The simple sampling device comprises an oak barrel, a sampling opening is formed in the oak barrel, a buckling ring is arranged in the sampling opening, a sampling stick is connected to the inner wall of the buckling ring, and a pull handle is installed on one side of the sampling stick; the end, away from the pull handle, of the sampling stick is connected with a limiting plug, a limiting ring is installed on the limiting plug, a sampling groove is formed in the surface of the sampling stick, and a blocking piece is connected to the sampling groove; and a sealing mechanism is arranged on the outer wall of the buckling ring. According to the simple sampling device for the large-container raw wine, through nesting between the sampling stick and the buckling ring, the sampling stick can be limited in the buckling ring, tight pulling of the sampling stick is achieved, the complete sealing performance of the oak barrel is guaranteed when force is not applied, the phenomenon that fermentation of internal wine bodi
