A bearing bracket 19 is fixedly installed below the right end of the main body 1, and the main body 1 is provided with a digging mechanism for collecting soil samples through the bearing bracket 19;

[0023] A cylinder 10 is fixedly installed at the upper end of the main body 1. The output end of the cylinder 10 is connected to a three-way pipe 12, and an exhaust valve 11 is installed on the three-way pipe 12. A closed inner cabin 13 fixedly communicating with the three-way pipe 12 is opened in the four legs of the main body 1. A strong spring 14 is vertically welded inside the top end of the closed inner cabin 13, and a piston 15 slidably sleeved in the closed inner cabin 13 is welded to the free end of the strong spring 14. The piston 15 is fixedly connected to a fixed pile 16 that extends out of the leg. The bottom end of the fixed pile 16 is conical to facilitate fixing in the ground and ensure the overall stability of the sampling device;

[0024] First of all, the cutting mechanism includes a limit slider 4 slidably installed on the guide rail 3 and fixedly connected to the dust cover 5. A cutter 6 for circumferentially cutting the soil is fixedly installed inside the dust cover 5. The cutter 6 is in a circular structure. A motor 7 is fixedly installed on the main body 1, and a rotating gear 8 is fixedly installed on the output end of the motor 7. A lifting rack 9 that meshes with the rotating gear 8 and is fixedly connected to the dust cover 5 is slidably installed on the main body 1. When the motor 7 rotates clockwise, it drives the dust cover 5 to rise, and when the motor 7 rotates counterclockwise, it drives the dust cover 5 to descend;

[0025] Secondly, the excavation mechanism includes a limit groove 17 opened on the main body 1, and a support slider 18 is slidably mounted in the limit groove 17, the support slider 18 is fixedly connected to a load-bearing bracket 19, a main arm 20 and a first hydraulic cylinder 21 are connected to each other via a pin on the load-bearing bracket 19, and a secondary arm 23 movably pulled by the first hydraulic cylinder 21 is installed via a pin in the main arm 20, a notch is provided at one end of the main arm 20 connected to the secondary arm 23 to prevent the secondary arm 23 from being excessively restricted when performing a pendulum motion, a second hydraulic cylinder 22 connected to the pin of the secondary arm 23 is installed via a pin on the main arm 20, a bucket 24 is fixedly mounted on the secondary arm 23, and the output end of the first hydraulic cylinder 21 is connected to the other end of the secondary arm 23 away from the bucket 24 via a pin, thereby realizing free movement of the excavation mechanism.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] Move the device to the designated position, open the cylinder 10, and the gas enters the closed inner chamber 13 through the three-way pipe 12, so that the pressure in the closed inner chamber 13 increases, thereby pushing the piston 15 to move downward, pulling one end of the fixed pile 16 into the soil, so that the device can be fixed on the ground during operation;

[0029] Run the cutting mechanism, turn on the motor 7, the output end of the motor 7 drives the rotating gear 8 to rotate counterclockwise, and drives the lifting rack 9 meshing with the rotating gear 8 to move vertically downward, so that the dust cover 5 uses the guide rail 3 as a path and the limit slider 4 as a fulcrum to move vertically, so that the dust cover 5 is attached to the ground, and the cutter 6 is operated to cut a rectangular soil block in the selected area. After the cutting work is completed, the output end of the motor 7 is controlled to rotate clockwise, and the dust cover 5 and the cutter 6 are controlled to reset;

[0030] By using the supporting slide block 18 as a fulcrum, the bearing bracket 19 is slid to a desired position in the limiting groove 17, and the main arm 20 is made to move in an arc by controlling the extension and retraction of the first hydraulic cylinder 21, and the secondary arm 23 is made to move in a pendulum by controlling the extension and retraction of the second hydraulic cylinder 22. The secondary arm 23 drives the bucket 24 to open a pit around the rectangular soil block cut out above, and the rectangular soil block is sampled through the position of the pit;

[0031] By rotating the exhaust valve 11, the gas in the closed inner chamber 13 is released, and the contraction of the strong spring 14 resets the piston 15, driving the fixed pile 16 back into the leg of the main body 1.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
