The invention relates to a soil sampler. The soil sampler comprises an annular base, the center of the base is fixedly connected with a guide base through connection boards, the center of the guide base is provided with a soil sampling rod in a sliding mode, the soil sampling rod is of a structure with a lead screw at the upper end and a soil sampling sleeve at the lower end, the lead screw is spirally connected with the interior of a lead screw base, the lead screw base and the annular base are fixedly connected through a plurality of fixing rods, the upper end of the lead screw is provided with a handle, insertion boards are fixedly connected with the peripheral side face of the base, are symmetrical with respect to the center of the base and face the lower portion of the base, and the lower end of the soil sampling sleeve is connected with a conical sleeve. The soil sampler is simple in structure and reasonable in design; the insertion boards of the outwards expanding structure and an annular flange on the lower surface of the base are arranged, so that the base is prevented from rotating relative to the ground, connection firmness is improved, and the soil sampling efficiency is improved; as the lower end of the soil sampling sleeve is connected with the conical sleeve, soil samples are prevented from disengaging from the soil sampling sleeve, one-time sampling is achieved, and the sampling efficiency is improved. The soil sampler is simple in structure and reasonable in design.
