The lower end of the first stopper rod 500 is as high as the lower end of the rotary rod 200.

Referring to fig. 2, the top surface of the first drill barrel 300 is provided with an annular escape groove 320, and the outer diameter of the escape groove 320 is smaller than that of the top surface of the first drill barrel 300. First groove 310 that slides has been seted up along the axial to first bore section of thick bamboo 300 outer wall, and the upper end in first groove 310 that slides is the closed setting, and the lower extreme runs through the setting. The escape groove 320 communicates with the first slide groove 310.

The first limiting rod 500 penetrates from the top surface of the avoiding groove 320, the lower end of the first limiting rod 500 is fixedly connected with a limiting block 510, and the limiting block 510 is located in the first sliding groove 310.

The motor 110 drives the rotating rod 200 to rotate, because the first limiting rod 500 limits the first drill barrel 300 circumferentially, the first drill barrel 300 slides downwards along the axial direction under the cooperation of the threads, and when the first drill barrel 300 slides to the lower end of the rotating rod 200, the limiting block 510 abuts against the closed end of the first sliding groove 310, so that the first drill barrel 300 cannot slide downwards any more.

Referring to fig. 1 and 5, a second limiting rod 600 is mounted on the rack 100, the second limiting rod 600 is vertically arranged, a limiting piece 700 with a circular cross section is fixedly connected to the top of the second limiting rod 600, the diameter of the limiting piece 700 is larger than that of the second limiting rod 600, the second limiting rod 600 penetrates through the rack 100 along the vertical direction, and the limiting piece 700 is erected on the top surface of the rack 100.

The outer wall of the second drill cylinder 400 is axially penetrated with a second sliding groove 410, and the second limiting rod 600 is embedded in the second sliding groove 410. The length of the second limiting rod 600 is equal to the sum of the lengths of the rotating rod 200 and the first drill barrel 300, and the second limiting rod 600 is formed by hinging and splicing two rods.

After the first drill barrel 300 rotates synchronously with the rotating rod 200, the second drill barrel 400 slides downwards along the axial direction due to the fact that the second drill barrel 400 is limited circumferentially by the second limiting rod 600 under the matching of the threads.

The implementation principle of a rock and soil drilling sampling tool in the embodiment of the application is as follows:

after placing the rock drilling sampling tool on the ground, fold the second gag lever post 600 earlier and expand the alignment, then insert first gag lever post 500 and second gag lever post 600 underground in advance.

When the motor 110 is operated, the motor 110 drives the rotary rod 200 to rotate, and the rotation of the rotary rod 200 enables the first drill barrel 300 to slide along the axial direction, so that the drilling is carried out towards the lower part of the ground, and at the moment, the second drill barrel 400 is in a static state relative to the first drill barrel 300.

When the first drilling barrel 300 slides to the lower end of the rotary rod 200, the first drilling barrel 300 does not slide continuously, but rotates synchronously with the rotary rod 200, and the rotation of the first drilling barrel 300 drives the second drilling barrel 400 to slide axially, so as to drill downwards continuously.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
