[0010] Further, a soil discharging mechanism is arranged inside the equipment housing. The soil discharging mechanism includes a soil discharging base fixedly connected to the tunneling disc. A driving motor is fixedly connected to the side wall of one end of the soil discharging base away from the tunneling disc. The output end of the driving motor is drivingly connected to a conveyor belt. A number of retaining plates are fixedly connected to the top of the soil discharging base. A number of soil deflecting partitions are fixedly connected to the inner wall of the tunneling head.

[0011] Further, a cleaning mechanism is arranged inside the tunneling head. The cleaning mechanism includes a fixed block fixedly connected to the inner wall of the equipment housing. One end of the fixed block close to the tunneling disc is rotatably connected to a rotating rod. The rotating rod rotatably penetrates the tunneling disc.

[0012] Further, the cleaning mechanism further includes a torsion spring sleeved on one end of the rotating rod close to the fixed block.

[0013] Further, a pressing mechanism is arranged inside the tunneling head.

[0015] The usage method of this pipeline laying tunneling machine includes the following steps:

[0016] Step 1: Pipe hole excavation: First, fix the tunneling machine inside the working pit, and then use a crane to place the equipment shell inside the tunneling groove at the top of the equipment base. At this time, start the hydraulic rod, and the hydraulic rod drives the pipe jacking base at one end to fit with the docking opening at one end of the equipment shell. At this time, the hydraulic rod pushes the equipment shell at one end of the pipe jacking base to move along the tunneling groove towards the soil layer.

[0017] Step 2: Soil discharge: When the tunneling head moves into the soil, the soil excavated by the cutter base enters the tunneling head. At this time, start the drive motor on the soil discharge base, and the output end of the drive motor rotates to drive the conveyor belt to rotate. The tunneling head rotates to drive several soil deflecting partitions inside the tunneling head to rotate. At this time, the soil deflecting partitions transfer the soil inside the tunneling head to the conveyor belt, and the conveyor belt rotates to transport the soil outside the equipment shell.

[0018] Step 3: Auxiliary cleaning: When the tunneling head rotates to drive several soil deflecting partitions to rotate, the cleaning column at one end of the cleaning rod on the right side of the rotating rod rubs against the inside of the tunneling head.

[0019] Step 4: Compacting the inner wall of the pipe hole: The tunneling rotating shaft drives the reset spring on the limit ring to contract. The movement of the tunneling rotating shaft drives the push rod on the moving ring to move towards the inside of the tunneling head. The push rod drives the sliding block at one end of the connecting rod to slide along the sliding groove towards the outside of the tunneling head. The sliding block drives the extrusion roller to slide towards the outside of the tunneling head. At this time, the extrusion roller presses against the inner wall of the pipe hole.

[0020] The present invention has the following beneficial effects:

[0021] (1) By setting up a cleaning mechanism in the present invention, when the tunneling head rotates to drive several soil deflecting partitions to rotate, the cleaning column at one end of the cleaning rod on the right side of the rotating rod rubs against the inside of the tunneling head. This setting is beneficial for the cleaning column to scrape the soil adhering to the inner wall of the tunneling head. The scraped soil falls onto the conveyor belt and is discharged along with the conveyor belt. When the soil deflecting partition rotates to the cleaning mechanism and presses against the cleaning column, the soil deflecting partition drives the rotating rod on the cleaning rod at one end of the cleaning column to rotate. At this time, the cleaning column rubs against the surface of the soil deflecting partition. This setting is beneficial for the cleaning column to remove the soil on the surface of the soil deflecting partition, thereby preventing a large amount of soil from adhering to the surface of the soil deflecting partition and improving the soil deflecting efficiency of the soil deflecting partition. When the soil deflecting partition drives the rotating rod on the cleaning rod at one end of the cleaning column to rotate, the rotating rod drives the torsion of the torsion spring on the fixed ring to increase. At the same time, the limit rod on the cleaning rod slides along the limit sliding groove. This setting is beneficial for ensuring the stable rotation of the cleaning column along the rotating rod. When the soil deflecting partition disengages from the extrusion of the cleaning column, under the action of the torsion of the torsion spring, the torsion spring drives the cleaning rod at one end of the rotating rod to reset, and the cleaning rod drives the cleaning column to reset. This setting is beneficial for the cleaning column to continuously clean the surfaces of several soil deflecting partitions inside the tunneling head.

[0022] (2) In the present invention, when using this pipe-laying tunneling machine, first fix the tunneling machine inside the working pit, and then use a crane to place the equipment housing inside the tunneling groove at the top of the equipment base. At this time, start the hydraulic rod, and the hydraulic rod drives the pipe jacking base at one end to fit with the docking opening at one end of the equipment housing. At this time, the hydraulic rod pushes the equipment housing at one end of the pipe jacking base to move along the tunneling groove towards the soil layer; start the tunneling motor, the rotation of the tunneling motor drives the output rotating shaft at the output end to rotate, the rotation of the output rotating shaft drives the tunneling rotating shaft to rotate, the rotation of the tunneling rotating shaft drives the tunneling bit to rotate, the rotation of the tunneling rotating shaft drives the connecting ring on the sliding key to rotate, the rotation of the connecting ring drives the tool base to rotate, the rotation of the tool base drives the tunneling head to rotate along the tunneling disc, and the rotation of the tool base drives several cutter heads to rotate. Such a setting is beneficial for several cutter heads in the tunneling mechanism to excavate the soil. By placing the equipment housing inside the tunneling groove, it is beneficial to ensure that the tunneling head at one end of the equipment housing drills into the soil in a straight line and at the same time ensure the stability of the equipment housing, thereby improving the quality of the pipe tunnel excavation; when the equipment housing completely drills into the soil, the hydraulic rod drives the pipe jacking base to move towards one end close to the extrusion base. At this time, use a crane to place the segmented pipe into the tunneling groove. At this time, the hydraulic rod drives the pipe jacking base to move towards the tail of the segmented pipe again. At this time, the pipe jacking base pushes the segmented pipe towards the docking opening of the equipment housing. At this time, the docking opening fits with one end of the segmented pipe, and the hydraulic rod drives the pipe jacking base to continue to push the segmented pipe into the pipe tunnel, thus completing the laying work of the segmented pipe.

[0023] (3) In the present invention, by setting a soil discharge mechanism, when the tunneling head moves into the soil, the soil excavated by the tool base enters the tunneling head. At this time, start the drive motor on the soil discharge base, and the rotation of the output end of the drive motor drives the conveyor belt to rotate. The rotation of the tunneling head drives several soil pushing partitions inside the tunneling head to rotate. At this time, the soil pushing partitions transfer the soil inside the tunneling head to the conveyor belt, and the rotation of the conveyor belt transports the soil outside the equipment housing. Such a setting is beneficial for timely discharging the excavated soil, thereby improving the excavation rate.

[0024] (4) In the present invention, by setting a pressing mechanism, when the tunneling head at one end of the equipment housing presses against the soil, the tunneling bit at one end of the tunneling rotating shaft presses against the soil. The tunneling bit is squeezed by the soil and drives the tunneling rotating shaft to slide along the output rotating shaft. At this time, the tunneling rotating shaft drives the return spring on the limit ring to contract. The movement of the tunneling rotating shaft drives the push rod on the moving ring to move towards the inside of the tunneling head. The push rod drives the sliding block at one end of the connecting rod to slide along the sliding groove towards the outside of the tunneling head. The sliding block drives the extrusion roller to slide towards the outside of the tunneling head. At this time, the extrusion roller presses against the inner wall of the pipe tunnel. Such a setting is beneficial for compacting the soil on the inner wall of the pipe tunnel, avoiding the soil inside the pipe tunnel from falling off, and thus improving the quality of the pipe tunnel.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Example 1, please refer to Figures 1 - 7 As shown, the present invention is a pipeline laying boring machine, including an equipment base 1. The right end of the equipment base 1 is fixedly connected with an extrusion base 11. One side of the extrusion base 11 close to the equipment base 1 is fixedly connected with a plurality of hydraulic rods 12. A boring groove 13 is opened at the top of the equipment base 1.

It also includes:

[0042] A boring mechanism 2, which includes a boring drill bit 213, a first boring component for driving the boring drill bit 213 to rotate, a tool bit 210, and a second boring component for fixing the tool bit 210;

[0043] The first excavation component includes an equipment housing 201 slidably arranged at an end of the excavation groove 13 away from the extrusion base 11, a docking opening 202 is opened at the end of the equipment housing 201 close to the jacking pipe base 15, a fixing rod 203 is fixedly connected to the inside of the equipment housing 201, a side of the equipment housing 201 away from the docking opening 202 is fixedly connected to a excavation motor 204, an output end of the excavation motor 204 is fixedly connected to an output shaft 205, an end of the output shaft 205 away from the excavation motor 204 is slidably connected to a excavation shaft 206, and an end of the excavation shaft 206 away from the output shaft 205 is fixedly connected to the excavation drill bit 213.

[0044] The second excavation component includes an excavation disk 207 fixedly connected to the end of the equipment housing 201 away from the docking opening 202, the side wall of the excavation disk 207 is rotatably connected to a excavation head 208, the end of the excavation head 208 away from the excavation disk 207 is fixedly connected to a plurality of tool bases 209, a plurality of cutter heads 210 are fixedly connected to the side of the tool base 209 away from the excavation head 208, the end of the tool base 209 away from the excavation head 208 is fixedly connected to a connecting ring 211, and the side wall of the excavation shaft 206 at one end close to the excavation drill bit 213 is fixedly connected to the excavation head 213. A plurality of sliding keys 212 are fixedly connected, and the sliding keys 212 are slidably connected inside the connecting ring 211. The function of this mechanism is to start the tunneling motor 204 by setting the tunneling mechanism 2. The tunneling motor 204 rotates to drive the output shaft 205 at the output end to rotate. The output shaft 205 rotates to drive the tunneling shaft 206 to rotate. The tunneling shaft 206 rotates to drive the tunneling drill bit 213 to rotate. The tunneling shaft 206 rotates to drive the connecting ring 211 on the sliding key 212 to rotate. The connecting ring 211 rotates to drive the tool base 209 to rotate. The rotation of the base 209 drives the excavation head 208 to rotate along the excavation disk 207, and the rotation of the cutter base 209 drives the plurality of cutter heads 210 to rotate. This arrangement is conducive to the plurality of cutter heads 210 in the excavation mechanism 2 to dig the soil. By placing the device housing 201 inside the excavation slot 13, it is conducive to ensuring that the excavation head 208 at one end of the device housing 201 drills into the soil along a straight line, while ensuring the stability of the device housing 201, thereby improving the quality of pipe hole excavation; when the device housing 201 is completely drilled into the soil, the hydraulic rod 12 drives the excavation head 208 to drill into the soil along a straight line, and ... The jacking pipe base 15 moves toward one end close to the extrusion base 11. At this time, the segmented pipe 14 is placed into the excavation groove 13 by a crane. At this time, the hydraulic rod 12 drives the jacking pipe base 15 to move toward the tail of the segmented pipe 14 again. At this time, the jacking pipe base 15 pushes the segmented pipe 14 to move toward the docking opening 202 of the equipment housing 201. At this time, the docking opening 202 fits with one end of the segmented pipe 14. The hydraulic rod 12 drives the jacking pipe base 15 to continue to push the segmented pipe 14 into the pipe hole, thereby completing the laying of the segmented pipe 14.

[0045] Inside the equipment housing 201, a soil discharging mechanism 3 is provided. The soil discharging mechanism 3 includes a soil discharging base 301 fixedly connected to the tunneling disc 207. A driving motor 302 is fixedly connected to the side wall of one end of the soil discharging base 301 away from the tunneling disc 207. The output end of the driving motor 302 is drivingly connected to a conveyor belt 303. A plurality of soil retaining plates 304 are fixedly connected to the top of the soil discharging base 301. A plurality of soil deflecting partitions 305 are fixedly connected to the inner wall of the tunneling head 208. The function of this mechanism is that by arranging the soil discharging mechanism 3, when the tunneling head 208 moves into the soil, the soil excavated by the tool base 209 enters the inside of the tunneling head 208. At this time, the driving motor 302 on the soil discharging base 301 is started, and the output end of the driving motor 302 rotates to drive the conveyor belt 303 to rotate. The tunneling head 208 rotates to drive a plurality of soil deflecting partitions 305 inside the tunneling head 208 to rotate. At this time, the soil deflecting partitions 305 transfer the soil inside the tunneling head 208 onto the conveyor belt 303, and the conveyor belt 303 rotates to convey the soil to the outside of the equipment housing 201. Such an arrangement is beneficial to timely discharge the excavated soil, thereby improving the excavation rate.

[0046] Embodiment 2, the difference feature from Embodiment 1 is that: as Figures 1 - 11 shown, a cleaning mechanism 4 is provided inside the tunneling head 208. The cleaning mechanism 4 includes a fixed block 401 fixedly connected to the inner wall of the equipment housing 201. One end of the fixed block 401 close to the tunneling disc 207 is rotatably connected to a rotating rod 402. The rotating rod 402 rotatably penetrates through the tunneling disc 207, and a fixed ring 403 is fixedly connected to the middle of the rotating rod 402.

[0047] The cleaning mechanism 4 further includes a torsion spring 404 sleeved on one end of the rotating rod 402 close to the fixed block 401. One end of the torsion spring 404 close to the fixed block 401 is fixedly connected to the fixed block 401, and one end of the torsion spring 404 close to the fixed ring 403 is fixedly connected to the fixed ring 403. One end of the rotating rod 402 far from the fixed block 401 is fixedly connected with a cleaning rod 405. One end of the cleaning rod 405 far from the rotating rod 402 is fixedly connected with a cleaning column 406. A limiting rod 407 is fixedly connected to the side wall of the cleaning rod 405. A limiting chute 408 is formed in the side wall of the tunneling disc 207. One end of the limiting rod 407 far from the cleaning rod 405 is slidably connected inside the limiting chute 408. The function of this mechanism is that by setting the cleaning mechanism 4, when the tunneling head 208 rotates to drive a plurality of soil scraping partitions 305 to rotate, the cleaning column 406 at one end of the cleaning rod 405 on the right side of the rotating rod 402 rubs against the inside of the tunneling head 208. Such a setting is beneficial for the cleaning column 406 to scrape the soil adhered to the inner wall of the tunneling head 208. The scraped soil falls onto the conveyor belt 303 and is discharged along with the conveyor belt 303. When the soil scraping partition 305 rotates to the cleaning mechanism 4 and presses against the cleaning column 406, the soil scraping partition 305 drives the rotating rod 402 on the cleaning rod 405 at one end of the cleaning column 406 to rotate. At this time, the cleaning column 406 rubs against the surface of the soil scraping partition 305. Such a setting is beneficial for the cleaning column 406 to remove the soil on the surface of the soil scraping partition 305, thereby avoiding a large amount of soil adhering to the surface of the soil scraping partition 305 and improving the soil scraping efficiency of the soil scraping partition 305; when the soil scraping partition 305 drives the rotating rod 402 on the cleaning rod 405 at one end of the cleaning column 406 to rotate, the torsion of the torsion spring 404 on the fixed ring 403 driven by the rotating rod 402 increases. At the same time, the limiting rod 407 on the cleaning rod 405 slides along the limiting chute 408. Such a setting is beneficial for ensuring the stable rotation of the cleaning column 406 along the rotating rod 402. When the soil scraping partition 305 is separated from the extrusion of the cleaning column 406, under the torsion action of the torsion spring 404, the torsion spring 404 drives the cleaning rod 405 at one end of the rotating rod 402 to reset, and the cleaning rod 405 drives the cleaning column 406 to reset. Such a setting is beneficial for the cleaning column 406 to continuously clean the surfaces of a plurality of soil scraping partitions 305 inside the tunneling head 208.

[0048] A pressing mechanism 5 is arranged inside the tunneling head 208. The pressing mechanism 5 includes a limiting ring 501 fixedly connected to one end of the tunneling rotating shaft 206 close to the output rotating shaft 205. A return spring 502 is sleeved on one side of the tunneling rotating shaft 206 close to the output rotating shaft 205. A ring groove is formed at one end of the tunneling rotating shaft 206 close to the connecting ring 211. A moving ring 503 is rotatably connected in the ring groove of the tunneling rotating shaft 206. A plurality of push rods 504 are fixedly connected to the side wall of the moving ring 503.

[0049] The pressing mechanism 5 further includes a connecting rod 505 rotatably connected to one end of the push rod 504 away from the moving ring 503. A plurality of sliding grooves 506 are formed in the side wall of the tunneling head 208. A sliding block 507 is slidably connected inside the sliding groove 506. The bottom of the sliding block 507 is rotatably connected to one end of the connecting rod 505. One end of the side wall of the sliding block 507 away from the connecting rod 505 is rotatably connected to an extrusion roller 508. The function of this mechanism is to set the pressing mechanism 5. When the tunneling head 208 at one end of the equipment housing 201 presses against the soil, the tunneling bit 213 at one end of the tunneling rotating shaft 206 presses against the soil. The tunneling bit 213 is pressed by the soil to drive the tunneling rotating shaft 206 to slide along the output rotating shaft 205. At this time, the tunneling rotating shaft 206 drives the return spring 502 on the limit ring 501 to contract. The movement of the tunneling rotating shaft 206 drives the push rod 504 on the moving ring 503 to move towards the inside of the tunneling head 208. The push rod 504 drives the sliding block 507 at one end of the connecting rod 505 to slide towards the outside of the tunneling head 208 along the sliding groove 506. The sliding block 507 drives the extrusion roller 508 to slide towards the outside of the tunneling head 208. At this time, the extrusion roller 508 presses against the inner wall of the pipe hole. This setting is beneficial to compact the soil on the inner wall of the pipe hole, avoid the soil inside the pipe hole from falling off, and thus improve the quality of the pipe hole.

[0050] The usage method of this pipe-laying tunneling machine includes the following steps:

[0051] Step 1: Pipe hole excavation: First, fix this tunneling machine inside the working pit, and then use a crane to place the equipment housing 201 inside the tunneling groove 13 on the top of the equipment base 1. At this time, start the hydraulic rod 12. The hydraulic rod 12 drives the pipe jacking base 15 at one end to fit with the docking opening 202 at one end of the equipment housing 201. At this time, the hydraulic rod 12 pushes the equipment housing 201 at one end of the pipe jacking base 15 to move along the tunneling groove 13 towards the soil layer.

[0052] Step 2: Soil discharge: When the tunneling head 208 moves into the soil, the soil excavated by the tool base 209 enters the inside of the tunneling head 208. At this time, start the drive motor 302 on the soil discharge base 301. The output end of the drive motor 302 rotates to drive the conveyor belt 303 to rotate. The tunneling head 208 rotates to drive a plurality of soil scraping partitions 305 inside the tunneling head 208 to rotate. At this time, the soil scraping partitions 305 transfer the soil inside the tunneling head 208 to the conveyor belt 303. The conveyor belt 303 rotates to transport the soil to the outside of the equipment housing 201.

[0053] Step 3: Auxiliary cleaning: When the tunneling head 208 rotates to drive a plurality of soil scraping partitions 305 to rotate, the cleaning column 406 at one end of the cleaning rod 405 on the right side of the rotating rod 402 rubs against the inside of the tunneling head 208.

[0054] Step 4: Compact the inner wall of the pipe hole: The tunneling rotating shaft 206 drives the return spring 502 on the limit ring 501 to contract. The movement of the tunneling rotating shaft 206 drives the push rod 504 on the moving ring 503 to move towards the inside of the tunneling head 208. The push rod 504 drives the sliding block 507 at one end of the connecting rod 505 to slide along the sliding groove 506 towards the outside of the tunneling head 208. The sliding block 507 drives the extrusion roller 508 to slide towards the outside of the tunneling head 208. At this time, the extrusion roller 508 is in contact with the inner wall of the pipe hole and compresses it.

[0055] A specific application of this embodiment is as follows:

[0056] Start the tunneling motor 204. The rotation of the tunneling motor 204 drives the output rotating shaft 205 at the output end to rotate. The rotation of the output rotating shaft 205 drives the tunneling rotating shaft 206 to rotate. The rotation of the tunneling rotating shaft 206 drives the tunneling bit 213 to rotate. The rotation of the tunneling rotating shaft 206 drives the connecting ring 211 on the sliding key 212 to rotate. The rotation of the connecting ring 211 drives the tool base 209 to rotate. The rotation of the tool base 209 drives the tunneling head 208 to rotate along the tunneling disc 207. The rotation of the tool base 209 drives several cutter heads 210 to rotate. Such a setting is beneficial for several cutter heads 210 in the tunneling mechanism 2 to excavate soil. By placing the equipment housing 201 in the tunneling groove 13, it is beneficial to ensure that the tunneling head 208 at one end of the equipment housing 201 drills into the soil along a straight line, and at the same time ensure the stability of the equipment housing 201, thereby improving the quality of pipe hole excavation; when the equipment housing 201 is completely drilled into the soil, the hydraulic rod 12 drives the pipe jacking base 15 to move towards one end close to the extrusion base 11. At this time, the segmented pipe 14 is placed into the tunneling groove 13 by a crane. At this time, the hydraulic rod 12 drives the pipe jacking base 15 to move towards the tail of the segmented pipe 14 again. At this time, the pipe jacking base 15 pushes the segmented pipe 14 towards the docking opening 202 of the equipment housing 201. At this time, the docking opening 202 coincides with one end of the segmented pipe 14. The hydraulic rod 12 drives the pipe jacking base 15 to continue to push the segmented pipe 14 into the pipe hole, thus completing the laying work of the segmented pipe 14; by setting the soil discharge mechanism 3, when the tunneling head 208 moves towards the inside of the soil, the soil excavated by the tool base 209 enters the inside of the tunneling head 208. At this time, start the drive motor 302 on the soil discharge base 301. The rotation of the output end of the drive motor 302 drives the conveyor belt 303 to rotate. The rotation of the tunneling head 208 drives several soil deflecting partitions 305 inside the tunneling head 208 to rotate. At this time, the soil deflecting partitions 305 transfer the soil inside the tunneling head 208 to the conveyor belt 303. The rotation of the conveyor belt 303 transports the soil to the outside of the equipment housing 201. Such a setting is beneficial for timely discharging the excavated soil, thereby improving the excavation rate.

[0057] By setting up the cleaning mechanism 4, when the tunneling head 208 rotates to drive a number of soil scraping partitions 305 to rotate, the cleaning column 406 at one end of the cleaning rod 405 on the right side of the rotating rod 402 rubs against the inside of the tunneling head 208. Such a setting is conducive to the cleaning column 406 scraping the soil adhered to the inner wall of the tunneling head 208. The scraped soil falls onto the conveyor belt 303 and is discharged along with the conveyor belt 303. When the soil scraping partition 305 rotates to the cleaning mechanism 4 and presses against the cleaning column 406, the soil scraping partition 305 drives the rotating rod 402 on the cleaning rod 405 at one end of the cleaning column 406 to rotate. At this time, the cleaning column 406 rubs against the surface of the soil scraping partition 305. Such a setting is conducive to the cleaning column 406 removing the soil on the surface of the soil scraping partition 305, thereby preventing a large amount of soil from adhering to the surface of the soil scraping partition 305 and improving the soil scraping efficiency of the soil scraping partition 305. When the soil scraping partition 305 drives the rotating rod 402 on the cleaning rod 405 at one end of the cleaning column 406 to rotate, the torsion of the torsion spring 404 on the fixed ring 403 driven by the rotating rod 402 increases. At the same time, the limiting rod 407 on the cleaning rod 405 slides along the limiting chute 408. Such a setting is conducive to ensuring the stable rotation of the cleaning column 406 along the rotating rod 402. When the soil scraping partition 305 is disengaged from the extrusion of the cleaning column 406, under the action of the torsion of the torsion spring 404, the torsion spring 404 drives the cleaning rod 405 at one end of the rotating rod 402 to reset, and the cleaning rod 405 drives the cleaning column 406 to reset. Such a setting is conducive to the cleaning column 406 continuously cleaning the surfaces of a number of soil scraping partitions 305 inside the tunneling head 208. By setting up the pressing mechanism 5, when the tunneling head 208 at one end of the equipment housing 201 presses against the soil, the tunneling bit 213 at one end of the tunneling rotating shaft 206 presses against the soil. The tunneling bit 213 is driven by the extrusion of the soil to drive the tunneling rotating shaft 206 to slide along the output rotating shaft 205. At this time, the tunneling rotating shaft 206 drives the reset spring 502 on the limiting ring 501 to contract. The movement of the tunneling rotating shaft 206 drives the push rod 504 on the moving ring 503 to move towards the inside of the tunneling head 208. The push rod 504 drives the sliding block 507 at one end of the connecting rod 505 to slide along the sliding groove 506 towards the outside of the tunneling head 208. The sliding block 507 drives the extrusion roller 508 to slide towards the outside of the tunneling head 208. At this time, the extrusion roller 508 presses against the inner wall of the pipe hole. Such a setting is conducive to compacting the soil on the inner wall of the pipe hole, preventing the soil inside the pipe hole from falling off, and thus improving the quality of the pipe hole.
