s1: moving the positioning block (36) along the guide frame (1), and rotating the screw rod (38), wherein the screw rod (38) enables the positioning column (37) to be in contact with a groove adjacent to the guide frame (1) through hydraulic oil, so that the positioning block (36) is limited;
S2: pulling out the limit column (33) outwards, releasing the limit of the trigger column (32), enabling the lower side of the drill rod (8) and the auger (15) to be in contact with the ground, and then starting the motor (3), and enabling the auger (15) to rotate in soil to drive the drill rod (8) and the sampling shell (13) to move downwards to a designated position;
S3: when the auger (15) is subjected to excessive resistance of soil in the downward moving process, the sliding frame (2) is limited by the contact of the hydraulic oil transmission stop column (20) and the groove of the guide frame (1), so that the auger (15) rotates in situ to turn over soil on the upper side of the auger, and the soil is fluffy to lighten the resistance of the auger (15) during rotation;
S4: when the drill rod (8) moves to a designated position, the motor (3) rotates to drive the iron column (11) to move up and down to knock the sampling shell (13) downwards, so that soil samples are extruded into the sampling shell (13), and collection of the soil samples is completed;
s5: after the sampling shell (13) moves downwards to a designated position, the earth samples in the sampling shell (13) are clamped by the mirror-image distributed clamping blocks (26), so that the earth samples are prevented from being lost in pits in the process of upwards moving the sampling shell (13), and the root parts of the earth samples are chopped by the cutter (30);
S6: after the soil sample is clamped by the clamping blocks (26), the motor (3) is controlled to rotate reversely, the sampling shell (13) is driven to move upwards after rotating in place, when the auger (15) moves to the ground, the carriage (2) is pushed to the uppermost side of the guide frame (1), the trigger column (32) is pushed upwards, and the carriage (2) is limited by the contact between the hydraulic oil transmission stop column (20) and the groove of the guide frame (1);
S7: the sampling shell (13) is pushed upwards, soil samples in the sampling shell are extruded by the lower side of the drill rod (8) to gradually extend out of the sampling shell (13) until the sampling shell (13) is reset, and the soil samples in the sampling shell are completely exposed, so that the soil samples are collected.
