The plurality of slide grooves 3 are arranged on the inner side of the slide groove limiting ring 2, so as to achieve the limiting effect and prevent the slider 4 from falling off when moving. An arc-shaped survey side plate 5 corresponding to the slide groove 3 is arranged below the slide groove 3, and a soil-breaking plate 18 bent inward is arranged at the bottom of the arc-shaped survey side plate 5; the top surface of the survey side plate 5 is connected to the slider 4 on the corresponding slide groove 3 through a connecting rod 6, and when the slider 4 slides to the center position of the slide groove 3 close to the bottom surface of the fixed plate 1, the plurality of survey side plates 5 are connected in sequence to form a cylindrical shell with closed side walls and a conical bottom structure, which is convenient for inserting into the soil to be surveyed. A handle 17 is installed on the top of the fixed plate 1.

[0019] A hydraulic rod 7 is provided in the middle of the bottom surface of the fixed plate 1, and a hollow movable column 8 is connected to the extended end of the hydraulic rod 7, and a sampling device is provided in the cavity of the hollow movable column 8; a plurality of first fixed seats 9 are provided on the outer wall of the hollow movable column 8, and a plurality of second fixed seats 10 are provided at the inner wall of the survey side plate 5 at positions corresponding to the first fixed seats 9, and a connecting plate 11 is provided between the first fixed seats 9 and the second fixed seats 10, and the two ends of the connecting plate 11 are respectively hinged to the corresponding first fixed seats 9 and the second fixed seats 10.
