The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Example 1: See Figure 1-Figure 7The present embodiment provides a portable non-disturbance soil sampling drill with adjustable depth, including a support base 100, a movable block 200, and a drive assembly 400. The drive assembly 400 is composed of an electric telescopic rod and a rotary motor. Four threaded rods 300 for support are rotatably connected to the support base 100. The movable block 200 is threadedly connected to the four threaded rods 300 respectively. The drive assembly 400 is connected to the top ends of the four threaded rods 300. A plurality of auxiliary support legs 500 are hinged on the side of the movable block 200. The bottom of the driving assembly 400 is equipped with a sampling drill assembly 600, and the sampling drill assembly 600 includes a drill body 610, and a plurality of threaded drill bits 620 are equipped on the outside of the drill body 610. A plurality of triangular grooves 630 that penetrate each other are opened at the bottom of the drill body 610. A cross bracket 650 is fixed inside the drill body 610, and an annular track block 660 is fixed on the cross bracket 650. A plurality of closing components 670 for closing the plurality of triangular grooves 630 are equipped at the bottom of the cross bracket 650. The closing component 670 includes a fixed block 671 fixed to the bottom of the cross bracket 650, and a slider 673 is slidably connected to the bottom of the fixed block 671. A hemispherical body 674 is fixed to one side of the slider 673, and a connecting block 672 is fixed to the other side of the slider 673. A spring 1 is fixed thereto, a closing plate 640 is fixed to the side of the connecting block 672, a plurality of linkage components 680 for controlling the plurality of closing components 670 are assembled in the annular track block 660, the linkage component 680 comprises a special-shaped hydraulic compartment 681 fixed inside the annular track block 660, and a metal block 682 slidably connected inside the annular track block 660, a liquid storage capsule 683 is fixed to one end of the special-shaped hydraulic compartment 681, a hydraulic rod 684 is slidably connected to the piston at one end of the special-shaped hydraulic compartment 681, a hemisphere 2 685 is fixed to the bottom of the hydraulic rod 684, hemisphere 1 674 is located on the motion trajectory of hemisphere 2 685, so when hemisphere 2 685 moves downward, it will squeeze hemisphere 1 674 to move, the liquid storage capsule 683 is an arc-shaped structure, and the liquid storage capsule 683 is connected to the metal block 682 on the side away from the special-shaped hydraulic compartment 681. The present application realizes non-disturbance drilling sampling operation of the soil by setting up a sampling drill bit assembly 600. After the driving assembly 400 rotates and pushes the sampling drill bit assembly 600 to open a hole in the soil layer to a suitable depth, the linkage assembly 680 controls the closing assembly 670 to open the triangular groove 630 to sample the soil sample of the corresponding soil layer, so as to avoid the problem of the sample being contaminated by samples of other soil layers.

[0025] When the above-mentioned device is used in practice, the sampling drill assembly 600 is first controlled by the driving assembly 400 to rotate clockwise and move downward. At this time, since the sampling drill assembly 600 is in a clockwise rotating state, the metal block 682 in the closing assembly 670 will not move and will fit on the inner wall of the annular track block 660. Therefore, when the sampling drill assembly 600 rotates clockwise and moves downward, it is in an integral state, and the drill bit 620 on the side of the drill body 610 is used to open a hole. As the drill body 610 penetrates into the soil layer at a suitable depth, the driving assembly 400 is closed, and the rotation direction of the rotating motor in the driving assembly 400 is adjusted to make its working state counterclockwise. At this time, since the drill body 610 is in a counterclockwise rotating state, under the action of inertia, the metal block 682 will slide toward the liquid storage capsule 683, thereby squeezing the liquid storage capsule 683, so that the internal liquid enters the special-shaped hydraulic chamber 681. At this time, the liquid is pressed into the water under the action of the liquid pressure. The pressure rod 684 will drive the hemisphere 2 685 to move downward. As the hemisphere 2 685 moves downward, it will squeeze the hemisphere 1 674 to move outward, thereby pushing the slider 673 to move, so that the connecting block 672 pushes the closing plate 640 to move and unfold. At this time, the triangular groove 630 of the drill bit body 610 is opened. As the drill bit body 610 rotates, the closing plate 640 extends to the outside of the drill bit body 610, scrapes off the soil layer sample and brings it into the drill bit body 610 for collection. After rotating counterclockwise for a certain period of time, the sampling drill bit assembly 600 is controlled by the driving assembly 400 to rotate clockwise and move upward. At this time, the linkage assembly 680 is reset, driving the closing assembly 670 to reset. When the sampling drill bit assembly 600 is located outside the soil layer and moves to the recovery area, the sampling drill bit assembly 600 is controlled by the rotating motor in the driving assembly 400 to rotate counterclockwise again, and the soil sample in the drill bit body 610 is taken out by centrifugal force. At this time, the sampling operation of the corresponding soil layer is completed.

[0026] Example 2: See Figure 4 , Figure 5 , Figure 8 , Fig. 9On the basis of the first embodiment, the present application is equipped with an auxiliary support device 700 inside the drill body 610, and the auxiliary support device 700 includes a central column 710 and an annular block 730 fixed inside the drill body 610. An annular block 1 720 is fixed in the middle of the central column 710. The side of the annular block 1 720 is hinged with a plurality of two-stage elastic support rods 770 for supporting the closing plate 640. The plurality of two-stage elastic support rods 770 are respectively hinged with the plurality of closing plates 640. The annular block 2 730 penetrates and is slidably connected to the center column 710. A spring 2 is fixed between the annular block 2 730 and the annular block 1 720. A plurality of L-shaped rods 750 connected to the hydraulic rod 684 are fixed to the top of the annular block 2 730. A plurality of extrusion rods 740 are fixed to the side of the annular block 2 730. The bottom of each extrusion rod 740 is rotatably connected to an extrusion wheel 760. The extrusion wheel 760 is located at the upper end of the two-stage elastic support rod 770. The extrusion wheel 760 is made of rubber. The present application supports the unfolded closing plate 640 by setting an auxiliary support device 700 to prevent the closing plate 640 from being squeezed and damaged during the rotation process. At the same time, the closing plate 640 with the support force provided by the auxiliary support device 700 can scrape the soil layer sample into the drill bit body 610 for collection.

[0027] When the above-mentioned device is used in practice, on the basis of Example 1, as the hydraulic rod 684 moves downward, the L-shaped rod 750 will be squeezed to move downward, and the annular block 2 730 will be pushed downward by the four L-shaped rods 750 at the same time. The extrusion rod 740 set on the side of the annular block 2 730 pushes the extrusion wheel 760 to move downward to squeeze the middle area of ​​the two-stage elastic support rod 770, thereby increasing the supporting force of the two-stage elastic support rod 770, and then the two-stage elastic support rod 770 provides supporting force to the closing plate 640 to increase the stability of the closing plate 640.

[0028] Example 3: See Figure 1 , Fig.10 On the basis of the first embodiment, the present application assembles a plurality of bracket assemblies 800 on the upper surface of the bracket base 100 for auxiliary support of the extension rod of the drive assembly 400. The bracket assembly 800 includes a bracket rod 810, a slide rod 830 is passed through and slidably connected to the bracket rod 810, a sleeve rod 820 is fixed to the side of the slide rod 830, a spring 3 is fixed between the sleeve rod 820 and the slide rod 830, and a ball 840 is rollingly connected to the inside of the sleeve rod 820 near the drive assembly 400. The present application provides auxiliary support for the extension rod body of the electric telescopic rod in the drive assembly 400 by setting the bracket assembly 800, so as to avoid damage to the rotating motor caused by the shaking generated during the hole opening operation, and at the same time, it can also reduce the vibration of the entire device.

[0029] When the above-mentioned device is used in practice, on the basis of Example 1, as the driving component 400 works, the extension rod of the internal electric telescopic rod is also rotating during the extension process. However, as the hole opening operation proceeds, a reverse vibration force is generated during the hole opening. At this time, after the ball 840 contacts it, it absorbs and releases these vibration forces, and can also provide multi-directional support force to it, thereby protecting the driving component 400.

[0030] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
