the arc-shaped block 4341, the arc-shaped block 4341 is fixedly connected with the end part of the U-shaped strip 433, and the inner ring surface of the arc-shaped block 4341 is provided with a containing groove 4342;
The rotary cylinder 4343, the rotary cylinder 4343 is rotatably provided in the accommodating groove 4342.
Through the rotating cylinder 4343 that sets up, the rotating cylinder 4343 rotates and sets up in holding tank 4342, when removing arc piece 4341, can make the rotating cylinder 4343 of arc piece 4341 inner circle offset with the outside of drilling rod 31 and extension bar 32, reach the fixed effect of centre gripping, simultaneously drilling rod 31 and extension bar 32 can rotate for the rotating cylinder 4343 of arc piece 4341 inner circle, and then can adjust the horizontal angle of drilling rod 31 and extension bar 32, then make things convenient for fixture block 53 and steering stopper 54 to insert draw-in groove 51 and steering limiting groove 52.
A sampling method of a soil sampling device for geological detection comprises the following steps:
firstly, an auxiliary assembly and disassembly assembly 4 is utilized to assist a drill rod 31, an extension rod 32 and a driving rod 33 to install, so that the ends of a plurality of spiral sections 34 outside the drill rod 31 and the extension rod 32 are connected end to form continuous spiral blades;
Step two, the sampling rod assembly 3 is driven by the driving unit 2 to rotate and simultaneously move downwards until the bottom of the sampling rod assembly 3 is screwed into a soil layer, so that drilling soil sampling is realized;
step three, when a deeper soil layer needs to be sampled, opening a connecting assembly 5 between the extension bar 32 and the end part of the driving rod 33, and then adding a new extension bar 32 and connecting the new extension bar 32 with the driving rod 33;
And step four, continuing to start the driving unit 2 so that the new extension bar 32 is screwed into the soil layer, thereby realizing the sampling work of the soil deeper in the small-sized equipment.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
