Provided is a non-belt automatic mechanized sampling system for a train, including: a working platform provided with a slide rail; a sampling mechanism slidably arranged on the slide rail and configured to collect materials from the carriage of the train; an integrated sample preparation component including a discharging mechanism and a feeder, a crusher, a constant mass dividing machine and a sample retention barrel arranged from top to bottom. The feeder transports the material to the crusher. The crusher crushes the material and transports the crushed material to the constant mass dividing machine. The constant mass dividing machine divides the crushed material into samples to the sample retention barrel, and the discarded material to the discharging mechanism. The discharging mechanism transports the discarded materials to the carriage.
