The outer diameters of the rotating cylinder 208, the first sliding cylinder 209, the second sliding cylinder 210, and the third sliding cylinder 211 decrease uniformly in sequence. The connecting bar 401 is welded inside the rotating cylinder 208. A second lead screw 402 is rotatably connected to the middle of the connecting bar 401. The other end of the second lead screw 402 is fixedly connected to the output end of the second stepping motor 403. A moving member 404 is threadedly connected to the second lead screw 402.

[0032] Embodiment 5

[0033] Please refer to Figure 7 As shown in the figure, the soil removal mechanism 5 includes a mounting seat 501. The mounting seat 501 is welded to the back of the crawler vehicle 1.

[0034] Those skilled in the art can understand that by driving the mounting block 503 to rotate through the output end of the third driving motor 502, the first electric push rod 504 and the scraper 505 rotate as a whole. Also, by extending or contracting the output end of the first electric push rod 504, the scraper 505 can be driven to reciprocate, thereby equivalently changing the "radius" of the scraper 505 during rotation.

[0035] Example 6

[0036] Please refer to Figure 2 、 Figure 12 and Figure 13 As shown in

[0037] Those skilled in the art can understand that by extending or contracting the output end of the second electric push rod 603, when extending, the three-way nozzle 604 is extended to the outside of the third sliding cylinder 211, and when contracting, the three-way nozzle 604 retracts and is received inside the third sliding cylinder 211.

[0038] Example 7

[0039] Please refer to Figure 12 and Figure 13 As shown in

[0040] Those skilled in the art can understand that by driving the threaded rod 702 to rotate through the output end of the servo motor 704, the two sealing plates 705 approach or separate from each other along the surface of the connecting rod 703. When approaching, the two sealing plates 705 block the through hole opened in the middle of the bottom end of the third sliding cylinder 211, and when separating, the through hole opened in the middle of the bottom end of the third sliding cylinder 211 is exposed.

[0041] Example 8

[0042] Please refer to Figure 3 As shown, the storage mechanism 8 includes a fixed block 801, which is welded to the front side of the crawler machine 1. The outer side of the fixed block 801 is fixedly connected to a connecting block 803 through a second guide rod 802.

The outer end of the third lead screw 804 is fixedly connected to the output end of a third stepping motor 805, and the third stepping motor 805 is installed on the outer side of the fixed block 801.

[0043] Those skilled in the art can understand that by driving the third lead screw 804 to rotate through the output end of the third stepping motor 805, the L-shaped plate 806 moves left and right reciprocally along the surface of the second guide rod 802, so as to drive a plurality of groups of drill bits 101 located on the L-shaped plate 806 to move left and right reciprocally.

[0044] The working principle and usage process of this device are as follows: S1. The crawler machine 1 moves the whole device to the position where drilling is required. By driving the first lead screw 202 to rotate through the output end of the first stepping motor 204, the lifting plate 205 moves downward along the surface of the first guide rod 203, and then drives the rotating plate 207, the rotating cylinder 208, the first sliding cylinder 209, the second sliding cylinder 210, the third sliding cylinder 211 and the drill bit 101 to move downward as a whole; S2. By driving the driving sprocket 214 to rotate through the output end of the second driving motor 213, driven by the chain 216, the driven sprocket 215 and the rotating cylinder 208 rotate as a whole, driving the first sliding cylinder 209, the second sliding cylinder 210, the third sliding cylinder 211 and the drill bit 101 to rotate as a whole. At the same time, by driving the second lead screw 402 to rotate through the output end of the second stepping motor 403, the moving part 404 moves, driving the scissor telescopic part 409 to be in a stretched state, driving the first sliding cylinder 209, the second sliding cylinder 210 and the third sliding cylinder 211 to move downward synchronously, realizing drilling, and also being able to control the drilling depth; S3. During the drilling process, when the inside of the drill bit 101 is adhered by soil, the drill bit 101 resets to its original position and rotates counterclockwise by 90 degrees through the output end of the first drive motor 206, driving the rotating plate 207 to rotate counterclockwise by 90 degrees. At this time, the output end of the first electric push rod 504 extends, driving the position of the scraper 505 to correspond to the inner wall position of the drill bit 101. Then, under the action of the output end of the second stepping motor 403, the drill bit 101 moves downward, and the scraper 505 pierces into the soil inside the drill bit 101. The output end of the third drive motor 502 drives the mounting block 503 to rotate, causing the first electric push rod 504 and the scraper 505 to rotate as a whole, realizing the removal of the soil inside the drill bit 101. During this drilling process, for each section of the hole drilled, soil removal is required to prevent the soil from remaining in the drilled hole and affecting the subsequent grouting effect. S4. If the drill bit 101 is damaged during the drilling process, the drill bit 101 also resets to its original position and rotates clockwise by 90 degrees through the output end of the first drive motor 206, driving the rotating plate 207 to rotate clockwise by 90 degrees. Secondly, the output end of the third stepping motor 805 drives the third lead screw 804 to rotate, causing the L-shaped plate 806 to move to the right along the surface of the second guide rod 802, thereby driving several groups of drill bits 101 located on the L-shaped plate 806 to move to the right. The output end of the transmission motor 308 drives the drive gear 304 to rotate, and all the toothed plates 307 leave the inside of the notch 102, removing the old drill bit 101. Similarly, when the output end of the transmission motor 308 rotates in the reverse direction, the installation of the new drill bit 101 is achieved. S5. During the drilling process, the output end of the servo motor 704 drives the threaded rod 702 to rotate, causing the two sealing plates 705 to approach each other along the surface of the connecting rod 703. The two sealing plates 705 block the through hole opened in the middle of the bottom end of the third sliding cylinder 211, preventing dust during drilling from entering the inside of the third sliding cylinder 211 and causing the three-way nozzle 604 to become blocked. S6. After the drilling is completed, the two sealing plates 705 move away from each other, exposing the through hole opened in the middle of the bottom end of the third sliding cylinder 211. Secondly, the output end of the second electric push rod 603 extends, realizing the extension of the three-way nozzle 604 to the outside of the third sliding cylinder 211. Then, the external slurry pump is started, and the three-way nozzle 604 grouts the hole. During the grouting process, the three-way nozzle 604 is also driven to move upward through the action of the output end of the second stepping motor 403 until the grouting is completed, and the whole process is automated, meeting the needs of the staff.
