Sampling device for medicine supervision

The utility model discloses a sampling device for medicine supervision, which comprises a box body, an electric telescopic rod and a PLC (programmable logic controller), and the electric telescopic rod is fixed on one side wall in the box body. The device has the beneficial effects that the electric telescopic rod, the fixing ring, the material level sensor and the PLC are arranged, and the batch and the single-batch dosage of the sampling are set by using the operation panel before sampling, so that in the sampling process, after a delivery pipe delivers a medicament into a liquid storage pipe, the liquid storage pipe is communicated with the liquid storage pipe, and the sampling time is shortened; the liquid level height of the medicament is measured through the material level sensor, when the liquid level height of the medicament reaches the set dosage height, the PLC enables the suction pump to stop extracting the medicament, and meanwhile, the electric telescopic rod drives the conveying pipe to move to
