Sampling device

The utility model discloses a sampling device, which is characterized in that corresponding support arms are arranged on two sides of a carrier of a sampling container, a sampling structure is arranged on a transverse arm in a sliding manner, and the sampling structure is provided with a first driving structure and a second driving structure which are respectively used for driving the sampling structure to transversely and vertically move for sampling; a sliding block connected with the supporting arm on the corresponding side, a guide rail matched with the sliding block and a third driving structure for driving the sliding block to slide are arranged on the corresponding side of the carrying frame. The corresponding first, second and third driving structures drive the sampling structure to accurately and quickly complete sampling; the walking frame formed by double supports of the supporting arms and the transverse arms at the corresponding positions improves the rigidity of the walking frame, and eliminates
