Multi-point monitoring soil heavy metal pollutant migration simulation experiment device and application

The invention relates to a multi-point monitoring soil heavy metal pollutant migration simulation experiment device and application. The multi-point monitoring soil heavy metal pollutant migration simulation experiment device comprises: a simulation bin, a spraying assembly, a rotating wheel type sampling assembly and a driving shaft, wherein the simulation bin is filled with soil, and a plurality of transparent windows capable of being opened are arranged on the front face of the simulation bin in an array mode; the rotating wheel type sampling assembly is matched with each transparent window; and the driving shaft is connected with the rotating wheel type sampling assemblies in the horizontal direction, so that a plurality of horizontal sampling sets are formed, the driving shaft with the specific vertical height can simultaneously drive the rotating wheel type sampling assemblies with the corresponding height to scrape and rotationally deliver soil samples to the transparent window, and the driving shaft i
