In order to facilitate the adjustment of the height of the two dust suction devices 2 and to facilitate the placement of the filter screen 2e, the front sides of the left and right sides of the frame 2d are fixedly connected with fixed blocks 3, and the front sides of the left and right sides of the filter screen 2e are fixedly connected with protrusions 4, and the surfaces of the two protrusions 4 are plugged and connected to the interior of the two fixed blocks 3. The interiors of the two fixed blocks 3 are provided with cavities 5, and the interiors of the two cavities 5 are provided with positioning components 6. The front and rear sides of the bottom of the collection box 1a are provided with lifting components. 7. Through the two positioning components 6, the filter 2e can be fixed to the inside of the frame 2d or removed from the inside of the frame 2d, so as to facilitate the fixing or removal of the filter 2e. Through the two lifting components 7, the two dust suction devices 2 can absorb dust as needed. In order to facilitate the fixation of the left protrusion 4 and the left fixed block 3, the left positioning component 6 includes two positioning blocks 601, two sliders 602, two pull rods 603 and two return springs 604. The surfaces of the two positioning blocks 601, the two sliders 602 and the two pull rods 603 are all movably connected to the inside of the left cavity 5. The rear sides of the two positioning blocks 601 are fixedly connected to the front sides of the two sliders 602.

The two return springs 604 both play a fixing and rebounding role, so that the two positioning blocks 601, the two sliders 602 and the two pull rods 603 can automatically rebound to their original positions after moving. In order to adjust the height of the dust suction device 2 according to the dust generated by obtaining the underground rock and soil layer samples, the front lifting assembly 7 includes a mounting block 701, two lifting columns 702 and a connecting block 703.The top of the mounting block 701 is fixedly connected to the front side of the bottom of the collecting box 1a, the tops of the two lifting columns 702 are fixedly connected to the bottom of the mounting block 701, the bottoms of the output ends of the two lifting columns 702 are fixedly connected to the top of the connecting block 703, the rear sides of the protection block 2b and the frame 2d are fixedly connected to the front side of the connecting block 703, and through the lifting assembly 7, the output ends of the two lifting columns 702 can drive the connecting block 703 to move upward or downward, so that the connecting block 703 drives the dust collecting device 2 upward or downward.

Through the two control blocks 8 and the limit blocks 9, the two positioning blocks 601, the two sliders 602 and the two pull rods 603 can only move upward or downward inside the left cavity 5, which plays a limiting role.

[0025] In order to make the connecting block 703 drive the dust suction device 2 to move better, the left and right sides of the mounting block 701 are fixedly connected with matching blocks 10, and the interiors of the two matching blocks 10 are slidably connected with moving blocks 11.

[0026] The working principle of this utility model:

[0027] When obtaining rock and soil stratification samples, the two fans 2c are operated so that the two fans 2c absorb the generated dust upwards and pass through the filter 2e, so that the filter 2e intercepts and absorbs the dust particles. When the height of the dust collecting device 2 is adjusted as needed, the two lifting columns 702 are operated so that the output ends of the two lifting columns 702 drive the connecting block 703 to move upward or downward, thereby causing the connecting block 703 to drive the dust collecting device 2 to move upward or downward. When it is necessary to pull out the filter 2e for cleaning, the two pull rods 603 are pulled in opposite directions by manpower. The movement of the two pull rods 603 will cause the two sliders 602 and the two positioning blocks 601 to move in opposite directions, thereby causing the two positioning blocks 601 to move out from the inside of the protrusion 4. At this time, the filter 2e can be pulled forward and moved out from the inside of the frame 2d to remove the filter 2e.

[0028] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0029] The above description is only a preferred embodiment of the utility model, and does not constitute any form of limitation to the utility model. Although the utility model has been disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this patent will not depart from the scope of the technical solution of the utility model.
