A plug rod 25 is inserted in the first plug hole 241, and the lower end of the plug rod 25 is inserted in the second plug hole 221. The mounting block 22 and the rotating rod 21 cannot rotate due to the restriction of the plug rod 25, so that the moving mechanism 2 can be used normally. The handle 6 is held to tilt the moving plate 5, the sliding rod 3 and the bracket 1 and push or pull them, so that the drilling rig body 4 can be conveniently transported. After arriving at the designated sampling point, the plug rod 25 is pulled out and the two rollers 23 are pushed to the side away from each other, so that the mounting block 22 and the rotating rod 21 rotate. After the rollers 23 are retracted, the bracket 1 can contact the ground, thereby improving the stability of sampling and preventing the rolling of the rollers 23 from affecting the sampling.

[0026] like Figure 4 As shown, a stepping block 26 is fixedly connected to the inner wall of the mounting groove 11. When the insertion rod 25 is inserted into the first insertion hole 241 and the second insertion hole 221, the mounting block 22 just contacts with the stepping block 26. The stepping block 26 is provided so that when the drilling rig body 4 needs to be moved after sampling is completed, by lifting one side of the bracket 1, the roller 23 on the same side is rotated back to its original position until the mounting block 22 abuts against the stepping block 26. At this time, the insertion rod 25 is inserted into the first insertion hole 241 and the second insertion hole 221, which can just fix the position of the roller 23. Put down this side of the bracket 1 and repeat the above operation to restore the position of the roller 23 on the other side. After the operation is completed, the drilling rig body 4 can be conveniently transported by holding the handle 6 to apply thrust or pull.

[0027] like Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the drilling rig body 4 includes a sampling barrel 41 that passes through the moving plate 5 and is rotatably connected thereto, and a first servo motor 42 installed on the moving plate 5. The output end of the first servo motor 42 is fixedly connected to a pulley 43. A connecting port 411 is provided at one end of the sampling barrel 41 located above the moving plate 5, and the connecting port 411 is transmission-connected to the pulley 43 through a transmission belt 44. A second servo motor 7 is fixedly installed on the bracket 1. A threaded rod 8 threadedly connected to the moving plate 5 is fixedly connected at the output end of the second servo motor 7. A cutting blade 46 is arranged at the lower end of the sampling barrel 41. The cutting blade 46 may be serrated or blade-shaped. In the present embodiment, it is blade-shaped. A sampling push rod 47 is connected to the inner thread of the sampling barrel 41 to facilitate pushing out the sample in the sampling barrel 41. The sampling push rod 47 (except for the rotating knob arranged thereon) is the same length as the sampling barrel 41. After reaching the sampling point, the sampling push rod 47 is rotated to adjust the sampling length in the sampling tube 41, and the threaded rod 8 is rotated through the rotation output of the second servo motor 7. Under the restriction of the slide bar 3, the movable plate 5 can move in the vertical direction, so that the drilling rig body 4 can move in the vertical direction, so that the sampling tube 41 moves to contact the sampling point, and the sampling tube 41 is rotated through the rotation output of the first servo motor 42 and the pulley 43, the transmission belt 44 and the connecting port 411. The cutting blade 46 rotates to cut the sample, and the sampling push rod 47 is rotated to help push the sample in the sampling tube 41 out.

[0028] like Figure 5 , Figure 6 As shown, a spiral blade 45 is disposed on the outer wall of the sampling tube 41 , and a plurality of chip discharge holes 412 are circumferentially provided at one end of the sampling tube 41 close to the cutting edge 46 for discharging debris.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a positioning ring 10 is fixedly connected inside the bracket 1, and the sampling tube 41 and the spiral blade 45 can just pass through the positioning ring 10. The positioning ring 10 is provided to help the projection of the positioning ring 10 around the sampling point to circle the sampling point before sampling, so as to facilitate the sampling tube 41 to be aligned with the sampling point.

[0030] like Figure 1 As shown, a battery 9 is arranged on the moving plate 5, and the first servo motor 42 and the second servo motor 7 are electrically connected to the battery and to a control unit (not shown in the figure).

[0031] The working principle of a portable shallow sampling drill for geological exploration in the present embodiment is: when in use, the mounting block 22 and the rotating rod 21 cannot rotate due to the restriction of the insertion rod 25, so that the moving mechanism 2 can be used normally, and the handle 6 is held to tilt the moving plate 5, the sliding rod 3 and the bracket 1 and push or pull, so that the drilling rig body 4 can be conveniently transported. After arriving at the designated sampling point, the insertion rod 25 is pulled out and the two rollers 23 are moved to the side away from each other, so that the mounting block 22 and the rotating rod 21 rotate. After the rollers 23 are retracted, the bracket 1 can contact the ground, thereby improving the stability of sampling and preventing the rolling of the rollers 23 from affecting the sampling.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
