Stirring and sampling device for liquid detection

The stirring and sampling device comprises a base, a motor, at least one stirring head and a sampling tube, the motor is fixedly installed on the base, the stirring head is rotatably installed on the base, a through hole is formed in the stirring head in the direction of a rotating shaft, the sampling tube is coaxially embedded in the through hole, and the sampling tube is arranged on the base. One end of a liquid outlet of the sampling pipe is fixedly connected with the base, a driving end of the motor is in transmission connection with the stirring head, and the motor selectively drives the stirring head to rotate around a rotating shaft relative to the base. The stirring and sampling device disclosed by the utility model can be used for selectively sampling while stirring or after stirring, the stirring operation and the sampling operation are mutually independent, the operation is flexible, automation can be realized, and meanwhile, a plurality of stirring heads and a plurality of sampling pipes can be si
