description The invention discloses a railway section polluted soil sampling device. The existing soil sampling device cannot perform targeted sampling on soil layers with different depths. An opening is formed in the lower end of a sampling barrel, a plugging conical head is arranged at the opening in the lower portion of the sampling barrel and connected with a driving mechanism, and the driving mechanism drives the plugging conical head to move up and down in the axis direction of the sampling barrel; the plugging conical head comprises a cylindrical section and a conical section, and the cylindrical section is slidably connected to the inner wall of the sampling cylinder; when the plugging conical head is located at the lowest position in the sampling barrel, the conical section extends out of the sampling barrel, and the cylindrical section is located in the sampling barrel; when the plugging conical head is located at the highest position in the sampling cylinder, a space for storing a soil sample is formed between
