Reagent row-type adding device

The embodiment of the invention discloses a reagent row-type adding device which comprises a horizontal walking mechanism, a lifting and rotating mechanism and a row-type liquid adding mechanism. The row-type liquid adding mechanism comprises puncture tubes and liquid adding tubes which are horizontally arranged in groups. The liquid adding tubes are sleeved inside the puncture tubes. The puncture tubes can move up and down relative to the liquid adding tubes so as to stretch out or withdraw the liquid adding tubes. The horizontal walking mechanism and the lifting and rotating mechanism drive the row-type liquid adding mechanism to conduct three-dimensional movement and rotation, and sample bottles with different arrangement modes can rapidly undergo liquid adding. Thus, liquid adding efficiency is boosted. In addition, due to the puncture tubes and the liquid adding tubes which sleeve each other, the sample bottles with seal membranes can automatically undergo puncturing and liquid adding. Therefore, sample
