The geological engineering density calibration type rock and soil sampling device comprises a sampler, and a shielding mechanism is installed on a feeding port of the sampler; a lifting mechanism used for driving the sampler into and out of soil is mounted on the sampler, an adjusting mechanism is mounted on the lifting mechanism, and the adjusting mechanism is used for stretching the lifting mechanism and enabling the lifting mechanism to rotate around the adjusting mechanism; wherein the adjusting mechanism comprises a pin shaft, the pin shaft is concentrically and fixedly connected with a dial, the lower portion of the dial is concentrically and rotatably connected with a rotating disc, and the rotating disc is provided with a pointer; a stretching piece used for stretching the lifting mechanism is fixed to the outer edge of the rotating disc. Other soil can be effectively prevented from being mixed into a collected sample, manpower is effectively saved, and drilling point locations are reduced. 本申请公开一种地质工
