Engineering sampling device

The utility model relates to the technical field of sampling, and discloses an engineering sampling device which comprises a bottom frame, the top of the bottom frame is fixedly connected with a supporting frame, one side face of the supporting frame is fixedly connected with a supporting plate, the top of the supporting plate is fixedly connected with a motor, and the output end of the motor is fixedly connected with a rotating rod. And the other end of the rotating rod penetrates through the supporting frame and is fixedly connected with a sampling frame. The sampling device has the following advantages and effects that when a worker needs to replace the sampling device, the driving motor controls the rotating rod to rotate so as to drive the sampling frame to be combined with the second rotating rod to turn over and rotate on the supporting plate, so that the worker can replace or install the sampling pipe conveniently, and when sampling materials need to be discharged, the sampling device is convenient to
