The invention discloses automatic solvent bottle replacing equipment for pretreatment of physical and chemical samples, which comprises a solvent supply device, a conveying vehicle and a mechanical arm, and the solvent supply device comprises a rack, a first driving assembly, a second driving assembly, a solvent bottle placing assembly and a sampling needle assembly; the solvent bottle placing assembly comprises a solvent bottle placing bracket, a first placing groove and a liquid level sensor; the sampling needle assembly comprises a sampling needle capable of extending into the solvent bottle; the conveying vehicle is provided with a second containing groove. The mechanical arm is installed on the conveying vehicle. The mechanical arm is provided with a mechanical claw assembly used for grabbing the solvent bottle. When the liquid level sensor detects that the liquid level of the solvent bottle reaches the preset liquid level height, the second driving assembly drives the sampling needle assembly to vertically move upwards, the first driving assembly drives the solvent bottle placing assembly to horizontally move outwards, the solvent supply device, the conveying vehicle and the mechanical arm are matched to realize full-automatic replacement of the solvent bottle, and the safety is better.
