The first operating rod 4 is lifted and lowered around the lifting ring 2, and the bottom of the first operating rod 4 is connected to the internal thread of the lifting ring 2, so that the spline slot 3 and the spline block 5 have a firm docking effect.

[0032] As a further solution of the present invention, a shrinkage sleeve 7 is movably installed on the upper end of the first operating rod 4, and the shrinkage sleeve 7 is sleeved on the outside of the second operating rod 8. The second operating rod 8 is inserted into the first operating rod 4 and can be telescopically movable. The shrinkage sleeve 7 plays a role in fixing the second operating rod 8. After the shrinkage sleeve 7 is loosened, the second operating rod 8 can be retracted into the first operating rod 4.

[0033] As a further solution of the present invention, the soil drill collar 10 rotates around the inner side of the main frame rod 1, and the original soil drill 11 moves up and down around the soil drill collar 10. A soil drill groove 18 is provided on the outer side of the original soil drill 11, and the rotation of the soil drill collar 10 drives the original soil drill 11 to rotate.

[0034] As a further solution of the present invention, after the auger collar 10 and the original auger 11 are rotated, the entire section of the original auger 11 is located on the inner side of the main frame rod 1, and the downward pressure bulldozer 6 is inserted into the interior of the original auger 11 through the lifting and lowering movement of the first operating rod 4. After the downward pressure bulldozer 6 is inserted into the original auger 11, the soil can be squeezed out.

[0035] As a further solution of the present invention, the lifting structure 13 includes a lifting rod 14, a lifting handle 15 and a lifting clamp 16. The two lifting rods 14 are embedded in both sides of the main frame rod 1, the lifting handle 15 is welded to the upper end of the lifting rod 14, and the two lifting clamps 16 are respectively welded to the lower ends of the two lifting rods 14.

The two rotating sleeves 20 are movably installed at the bottom of both sides of the main frame rod 1, the spring telescopic rod 21 is fixedly installed at the rear end of the rotating sleeve 20, the filter frame 22 is fixedly installed at the end of the spring telescopic rod 21 away from the rotating sleeve 20, and the soil filter 23 is fixedly installed at the center of the filter frame 22. The spring telescopic rod 21 has an elastically retractable structure, so that the filter frame 22 can pass over the edge of the original soil auger 11 when rotating.

[0039] As a further solution of the present invention, the filter frame 22 is located behind the original soil auger 11. When the rotating sleeve 20 rotates downward, the filter frame 22 and the soil filter 23 are fitted and connected with the end of the original soil auger 11, and the soil filter 23 can filter the soil discharged by the original soil auger 11.

[0040] It should be noted that the present invention is a portable soil sampler for environmental assessment. When in use, the sampler is grasped and moved as a whole by operating the handle 9, the original soil drill 11 is aligned with the soil to be sampled, and then force is applied downward to insert the original soil drill 11 into the soil, and then the original soil drill 11 wraps the soil, and then the original soil drill 11 is lifted upward to obtain the soil wrapped in the original soil drill 11, so as to complete the on-site sampling of the soil;

[0041] When the original soil auger 11 is lifted upward, the latch rod 17 is pulled out, so that the lifting rod 14 is released from the fixed connection with the main frame rod 1, and then the lifting handle 15 is pulled upward to drive the lifting rod 14 and the lifting clamp block 16 to move upward. The lifting clamp block 16 drives the original soil auger 11 to be quickly lifted upward from the soil auger collar 10 through the connection with the lifting docking plate 12, so that the original soil auger 11 can be quickly lifted out without lifting the entire sampler;

[0042] When taking out the soil in the original soil auger 11, after the original soil auger 11 is taken out of the soil, the lifting handle 15 is pushed down to reset the original soil auger 11, and then the original soil auger 11 and the soil auger collar 10 are rotated 90 degrees, so that the upper and lower positions of the original soil auger 11 are exchanged, and the upper end enters the inner side of the main frame rod 1, and after the first operating rod 4 is separated from the lifting collar 2 and pressed down, the downward pressing bulldozer 6 can enter the original soil auger 11 to squeeze the soil, so as to squeeze and collect the soil from the original soil auger 11;

[0043] When the soil is squeezed out, the rotating sleeve 20 is rotated downward so that the filter frame 22 and the soil filter 23 fit with the port of the original soil auger 11. Therefore, when the bulldozer 6 is pressed down to push out the soil in the original soil auger 11, the soil passes through the soil filter 23 and is discharged from the port of the original soil auger 11. The soil filter 23 is used to refine and crush the soil and filter large particles of stone at the same time.

[0044] When the soil is squeezed out of the original soil auger 11, the original soil auger 11 is fully rotated to the inside of the main frame rod 1, and the pusher block 6 is pressed down to be located at the bottom of the original soil auger 11. The first operating rod 4 also drops to the lowest point, and then the shrinkage sleeve 7 is loosened to allow the second operating rod 8 to be retracted into the first operating rod 4, so that the sampler can quickly realize the overall storage after sampling and discharging the soil.
