Description

Technical Field

[0001] The invention relates to the technical field of road coring detection, in particular to a coring device for road detection. Background Art

[0002] Road coring is an important quality inspection method that is used to evaluate the quality and performance of roads. It is done by drilling holes on the road surface to obtain core samples of road materials for detailed inspection and analysis. The purpose of this method is to evaluate key quality indicators such as the road's structural strength, thickness, flatness, and anti-skid structural depth, thereby ensuring the safety and durability of the road.

[0003] Existing coring work is usually carried out at a specific coring position on the road surface by a coring device. Since coring is carried out at multiple positions each time, the coring device is usually movable to facilitate the movement of the coring device. However, the coring device needs to be kept stable during the coring process. Therefore, when starting to coring, two staff members are required to cooperate with each other to lift up one side of the coring device and adjust the position of the moving wheel of the coring device so that the base of the coring device is directly placed on the ground. When the bottom surface is uneven, it will also cause the overall instability of the sampling device, affecting the normal progress of the coring work.

[0004] After the coring is completed, two workers need to cooperate with each other to return the moving wheel to its original position and carry out the next coring work, which makes the coring work steps complicated.

[0005] At the same time, at least two staff members cooperate to complete the task, which increases the number of coring staff members assigned and affects the coring efficiency. After the coring is completed, some samples will be stuck inside the coring drill bit, requiring staff assistance to remove the samples from the inside of the drill bit.

[0006] Furthermore, during the sampling process, the position of the sampling device needs to be offset to prevent the sample from falling into the hole at the sampling position, resulting in high labor intensity and low work efficiency during the entire sampling process. Summary of the invention

[0027] 2. When sampling begins by coordinating the supporting mechanism with the stabilizing mechanism, when adjusting the position of the coring drill bit by adjusting the screw, first lift the mobile base upward to a vacant position, and the staff only needs to turn the adjusting screw to complete the vacant work of the mobile base, thereby improving the convenience of operation. At the same time, the position of the coring drill bit is adjusted synchronously while turning the adjusting screw, thereby improving the coring efficiency.

[0028] 3. Through the setting of multiple adjustable elastic telescopic rods, when the road surface at the coring position is uneven, the multiple adjustable elastic telescopic rods can freely extend and retract according to their own positions, so that the bottom end of the base plate can be more closely fitted to the road surface at the coring position, and the rubber pad can be used to increase the friction with the road surface, making the device more stable during the entire coring process.

DETAILED DESCRIPTION

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0044] like Figure 1 As shown, a coring device for road inspection includes a mobile base 1, and a coring mechanism 3 for road coring is arranged on the upper surface of the mobile base 1. The coring device also includes a supporting mechanism 4 for lifting the mobile base 1 upward, and the supporting mechanism 4 is arranged on the upper surface of the mobile base 1. The coring device also includes a stabilizing mechanism 5 for maintaining the stability of the mobile base 1 when the coring mechanism 3 performs a coring operation, and the stabilizing mechanism 5 is arranged on the mobile base 1. The coring device also includes a sample receiving mechanism 6 for receiving the coring sample, and the sample receiving mechanism 6 is arranged on the mobile base 1. The coring device also includes a knocking mechanism 2 for assisting the coring sample to be taken out from the inside of the coring mechanism 3, and the number of the knocking mechanisms 2 is two and they are symmetrically arranged on the mobile base 1 front and back.

[0045] like Figure 2 As shown, the coring mechanism 3 includes a gate-shaped sliding frame 31 fixedly connected to the upper surface of the mobile base 1, a mounting sliding seat 33 is slidably connected to the vertical section of the gate-shaped sliding frame 31, an adjusting screw 32 is rotatably connected to the horizontal section of the gate-shaped sliding frame 31, a transmission unit 35 is fixedly connected to the right side of the mounting sliding seat 33, a coring drill bit 36 ​​is detachably installed on the bottom end of the transmission unit 35, a water injection unit 34 is arranged on the upper surface of the transmission unit 35, the adjusting screw 32 is threadedly connected to the mounting sliding seat 33, an engine is fixedly installed on the left side of the mounting sliding seat 33, and a belt transmission is used between the transmission unit 35 and the engine output shaft.

[0046] like Figure 3 As shown, the support mechanism 4 includes a support member 42 arranged on the upper surface of the mobile base 1, an installation box 41 is fixedly installed on the upper surface of the mobile base 1 and located on the right side of the support member 42, a bevel gear transmission box 44 is fixedly installed on the support member 42, and a control member 43 for controlling the drive transmission is arranged on the support member 42.

[0047] like Figure 3 and Figure 4 As shown, the support member 42 includes a gate-shaped support frame 421 fixedly connected to the upper surface of the mobile base 1, and two vertical sections of the gate-shaped support frame 421 are rotatably connected with a bidirectional screw 422. Two front-to-rear symmetrical adjusting sliders 423 are threadedly connected to the circumferential surface of the bidirectional screw 422. The upper surface of the adjusting slider 423 is slidably connected to the lower surface of the horizontal section of the gate-shaped support frame 421. The bottom end of the adjusting slider 423 is hinged with a connecting strut 424, and the bottom ends of the two connecting struts 424 are jointly hinged with a support block 425. The front end of the bidirectional screw 422 is connected to the first bevel gear shaft on the left side of the bevel gear transmission box 44 through a belt drive.

[0048] like Figure 5 As shown, the stabilizing mechanism 5 includes limit slide bars 51 elastically slidably connected to the four corners of the upper surface of the mobile base 1, the bottom ends of the four limit slide bars 51 all penetrate the lower surface of the mobile base 1 and are fixedly connected to a bottom plate 52, the lower surface of the bottom plate 52 is elastically slidably connected to a plurality of evenly distributed adjustable elastic telescopic rods 53, the bottom ends of the adjustable elastic telescopic rods 53 are fixedly connected to a rubber pad 54, and a matching card slot 55 adapted to the sample connecting plate 62 is provided on the right side of the upper surface of the bottom plate 52.

[0049] During specific use, the movable base 1 is first moved to the coring position, and then the adjusting screw 32 is rotated to drive the installation sliding seat 33 to slide downward on the gate-shaped sliding frame 31, pushing the coring drill bit 36 ​​to move downward and gradually approach the coring position. When the adjusting screw 32 starts to rotate, the adjusting screw 32 drives the bidirectional screw 422 to rotate on the gate-shaped support frame 421 through the control member 43. At this time, the two adjusting sliders 423 move toward each other as the bidirectional screw 422 rotates, and at the same time, the supporting block 425 is pushed downward by the connecting strut 424, generating a downward thrust on the bottom plate 52, and the bottom plate 52 moves downward, driving the limiting slide bar 51 to slide downward on the movable base 1 at the same time.

[0050] When the rubber pad 54 contacts the ground, as the bottom plate 52 continues to move downward, the movable base 1 is lifted upward, and the adjustable elastic telescopic rod 53 is pushed to move toward the inside of the bottom plate 52. At this time, multiple evenly distributed adjustable elastic telescopic rods 53 move different distances into the bottom plate 52 according to the different flatness of the ground at their locations. When the bottom plate 52 moves to fit the ground, some of the adjustable elastic telescopic rods 53 at the pitted position will extend into the inside of the pitted position, and the adjustable elastic telescopic rods 53 at the flat position will completely retract into the inside of the bottom plate 52. At this time, multiple adjustable elastic telescopic rods 53 form an adaptive fit on the ground at their locations, avoiding the situation where the bottom surface of the bottom plate 52 cannot fully contact the ground and shakes when sampling on uneven ground, so as to ensure the stability of the device during coring.

[0051] like Figure 6 As shown, the control member 43 includes a fixed bracket 431 fixedly connected to the right side of the door-shaped support frame 421, the right end of the fixed bracket 431 is rotatably connected to a rotating ring 432, and a rotating disk 437 is rotatably connected to the inner circumferential surface of the rotating ring 432, and the right side of the rotating disk 437 is fixedly connected to two elastic telescopic support rods 436 symmetrical in upper and lower directions, and the right ends of the two elastic telescopic support rods 436 are commonly fixedly connected to a linkage sleeve 435, and the right side of the linkage sleeve 435 is fixedly connected to a linkage shaft 433, and the right side of the linkage sleeve 435 is clamped with two front-to-back symmetrical adjustment limit pins 434, and the left end of the adjustment limit pin 434 passes through the left side of the linkage sleeve 435 and is rotatably connected to the right side of the rotating disk 437, and the rotating ring 432 is connected to the second bevel gear shaft on the right side of the bevel gear transmission box 44 through a belt drive.

[0052] like Figure 6 and Figure 7 As shown, the bottom end of the adjusting screw 32 passes through the interior of the installation box 41 up and down and is provided with a bevel gear, and the right end of the linkage shaft 433 passes through the interior of the installation box 41 left and right and is also provided with a bevel gear. The bevel gear on the adjusting screw 32 meshes with the bevel gear on the linkage shaft 433 (as shown in FIG. Figure 7 As shown in the figure, a plurality of fins are arranged on the circumferential surface of the adjusting limit pin 434, a slot corresponding to the fins on the adjusting limit pin 434 is opened on the linkage sleeve 435, two upper and lower symmetrical limit rods are fixedly connected to the left side of the linkage sleeve 435, and a plurality of groups of limit holes corresponding to the positions of the two limit rods are opened on the right side of the rotating ring 432.

[0053] During specific use, when the bidirectional screw 422 is driven to rotate on the gate-shaped support frame 421 through the control part 43, the adjusting screw 32 rotates the bevel gear at its bottom end to cooperate with the bevel gear adjusting screw 32 at the right end of the linkage shaft 433 to drive the linkage shaft 433 to rotate synchronously. At this time, the linkage shaft 433 drives the rotating ring 432 to rotate on the fixed bracket 431 through the linkage sleeve 435. The fixed bracket 431 is connected to the second bevel gear shaft on the bevel gear transmission box 44 through a belt. The second bevel gear shaft drives the bidirectional screw 422 to rotate on the gate-shaped support frame 421 through the first bevel gear shaft and the bidirectional screw 422 belt transmission.

[0054] It should be noted that when the base plate 52 completely lifts the movable base 1, the rotation of the adjusting screw 32 is stopped, the linkage sleeve 435 is pulled to the right, and the elastic telescopic support rod 436 is stretched. When the linkage sleeve 435 is completely separated from the fin on the adjustment limit pin 434, the limit plug rod on the linkage sleeve 435 is separated from the limit hole on the rotating ring 432. At this time, the two adjustment limit pins 434 are rotated ninety degrees. At this time, the fin on the adjustment limit pin 434 and the card slot on the linkage sleeve 435 are in a vertical state. At this time, the pulling force on the linkage sleeve 435 is cancelled, and the linkage sleeve 435 is driven to return to its original position under the action of the elastic force of the elastic telescopic support rod 436 itself.

[0055] Since the slot on the linkage sleeve 435 and the fin on the adjustment limit pin 434 are in a vertical state, the fin on the adjustment limit pin 434 generates a supporting force on the linkage sleeve 435, so that the linkage sleeve 435 cannot be restored to its original position, and the limit plug rod on the linkage sleeve 435 and the limit hole on the rotating ring 432 are in a separated state. At this time, when the adjusting screw 32 continues to rotate to drive the linkage sleeve 435 to rotate through the linkage shaft 433, the linkage sleeve 435 drives the rotating disk 437 to rotate on the inner side of the rotating ring 432, and the rotating ring 432 remains stationary on the fixed bracket 431, that is, the adjusting screw 32 continues to rotate and no longer drives the bidirectional screw 422 to rotate on the door-shaped support frame 421.

[0056] like Figure 2 and Figure 8As shown, the sample receiving mechanism 6 includes a sample receiving plate 62 which is elastically slidably connected to the movable base 1 and is located below the coring drill bit 36 ​​and moves left and right. The movable base 1 is provided with a transmission member 61 which drives the sample receiving plate 62 to move left and right. Two front-to-back symmetrical connecting pulleys 63 are rotatably connected to the door-shaped sliding frame 31. When coring starts, the supporting mechanism 4 cooperates with the stabilizing mechanism 5 to lift the movable base 1 off the ground and the sample receiving plate 62 slides to the left. When coring is completed, the coring drill bit 36 ​​moves upward and the sample receiving plate 62 slides to the right to contact the coring drill bit 36. When the sample receiving plate 62 slides to below the coring drill bit 36, the knocking mechanism 2 starts to knock on the outer wall of the coring drill bit 36.

[0057] like Figure 2 and Figure 8 As shown, the transmission member 61 includes two symmetrical mounting grooves 613 provided on the front and rear surfaces of the mobile base 1, and the front and rear surfaces of the mobile base 1 and the left and right sides of the mounting grooves 613 are rotatably connected with guide pulleys 615, and the interior of the mounting grooves 613 is slidably connected with a connecting slider 614, and a synchronization bar 616 is fixedly connected between the opposite surfaces of the two connecting sliders 614, and the right side surface of the synchronization bar 616 is fixedly connected to the connecting plate 62, and the right side surface of the connecting slider 614 is fixedly connected with an elastic telescopic connecting rod 612, and the telescopic end of the elastic telescopic connecting rod 612 passes through the left side surface of the connecting slider 614 and is fixedly connected with a pull rope 611, and the end of the pull rope 611 away from the elastic telescopic connecting rod 612 successively passes around the guide pulley 615 on the left side of the mobile base 1, the guide pulley 615 on the right side and the connecting pulley 63 and is fixedly connected to the mounting sliding seat 33, and a placement hole compatible with the elastic telescopic connecting rod 612 is provided at the right end position of the corresponding elastic telescopic connecting rod 612 on the mobile base 1.

[0058] During specific use, after the transmission between the linkage sleeve 435 and the rotating ring 432 is cancelled, the adjusting screw 32 is rotated again. At this time, the adjusting screw 32 continues to push the mounting sliding seat 33 to slide downward on the door-shaped sliding frame 31. When the adjusting screw 32 starts to drive the mounting sliding seat 33 to start sliding downward, the mounting sliding seat 33 generates a downward pulling force on the pull rope 611. The pull rope 611 first passes through the connecting pulley 63, and then passes through the guide pulley 615 on the right side of the mobile base 1 and the guide pulley 615 on the left side to generate a left pulling force on the elastic telescopic connecting rod 612, and the elastic telescopic connecting rod 612 is pulled out from the placement hole on the mobile base 1. The setting of the placement hole can provide sufficient displacement space for the elastic telescopic connecting rod 612 to prevent the connecting slider 614 from failing to return to its original position completely.

[0059] When the elastic telescopic connecting rod 612 drives the connecting slide block 614 to slide inside the installation slide groove 613, the two connecting slide blocks 614 drive the sample plate 62 to slide to the left on the movable base 1 through the synchronization bar 616, and the synchronization bar 616 is slid to the left in advance to avoid affecting the normal falling of the coring drill bit 36. With the continuous rotation of the adjusting screw 32, the coring drill bit 36 ​​is pushed to move downward until it is close to the ground. At this time, the engine is started and the coring drill bit 36 ​​starts to rotate through the belt and the transmission unit 35. The adjusting screw 32 is continued to be rotated to push the coring drill bit 36 ​​to move downward to start coring work, and the water injection unit 34 is opened to continuously supply water to the inside of the coring drill bit 36, thereby reducing the working temperature of the coring drill bit 36 ​​during coring and reducing the generation of dust.

[0060] It should be noted that when the installation sliding seat 33 starts to move downward to push the core drilling bit 36 ​​closer to the ground, until the entire sampling process is completed, the installation sliding seat 33 continues to move downward and continues to generate tension on the pull rope 611. When the pull rope 611 drives the connecting slider 614 to slide to the left end of the installation slide groove 613, the sample connecting plate 62 is completely retracted to the left on the movable base 1. At this time, when the installation sliding seat 33 continues to pull the pull rope 611, the pull rope 611 cooperates with the extension of the elastic telescopic connecting rod 612 to ensure that the pull rope 611 will not limit the installation sliding seat 33 during the downward movement of the installation sliding seat 33. The elasticity of the elastic telescopic connecting rod 612 itself can ensure the smooth downward movement of the installation sliding seat 33.

[0061] like Fig. 9 and Fig.11 As shown, the knocking mechanism 2 includes two front-to-back symmetrical connecting members 21 arranged on a door-shaped sliding frame 31, a support seat 23 is fixedly connected to the upper surface of the mobile base 1 and located below the connecting member 21, a pushing member 22 is arranged on the upper surface of the support seat 23, and a knocking member 24 is arranged on the left side of the pushing member 22.

[0062] like Fig. 9 and Fig.10 As shown, the connecting member 21 includes a connecting support plate 211 fixedly connected to the mounting sliding seat 33, the upper surface of the connecting support plate 211 elastically slides up and down and is penetrated by a connecting vertical rod 212, the bottom end of the connecting vertical rod 212 is fixedly connected to a sleeve 213, a plurality of mounting tubes 214 are penetrated and fixedly connected on the circumferential surface of the sleeve 213, the interior of the mounting tube 214 is fixedly connected with an elastic limiting seat 215, and the end of the elastic limiting seat 215 close to the axis of the sleeve 213 is spherical and penetrates to the interior of the sleeve 213.

[0063] like Fig.11The top of the toothed plate 221 is fixedly connected to the upper surface of the connecting ear plate 224 and is slidably connected to the toothed plate 221. The bottom end of the toothed plate 221 is fixedly connected to two sliding guide rods 222. The positions of the corresponding sliding guide rods 222 on the speed change gear box 223 are fixedly connected to connecting ear plates 224. The top of the sliding guide rod 222 penetrates the upper surface of the connecting ear plate 224 and is slidably connected to the connecting ear plate 224. A return spring is sleeved on the circumferential surface of the sliding guide rod 222 and is located between the connecting ear plate 224 and the bottom end of the toothed plate 221. An annular groove is provided on the circumferential surface of the pin 225. The size of the annular groove is adapted to the size of the spherical end of the elastic limit seat 215. The elastic strength between the connecting vertical rod 212 and the connecting support plate 211 is less than the elastic strength of the return spring.

[0064] During specific use, when the installation sliding seat 33 moves downward, it drives the connecting vertical rod 212 to move downward synchronously. When the connecting vertical rod 212 drives the sleeve 213 to continue to move downward to the top of the pin 225, as the connecting vertical rod 212 continues to move downward, the sleeve 213 is sleeved on the pin 225, and at the same time, the spherical end of the elastic limit seat 215 is clamped in the annular groove on the pin 225. At this time, as the installation sliding seat 33 continues to descend, the pin 225 generates a supporting force on the sleeve 213, pushing the connecting support plate 211 to slide downward on the circumferential surface of the connecting vertical rod 212. When the installation sliding seat 33 moves downward and drives the coring drill bit 36 ​​to complete the coring work, the driving of the driving motor and the water injection work of the water injection unit 34 are stopped.

[0065] At this time, the linkage sleeve 435 is pulled to the right, and the adjustment limit pin 434 is rotated to make the fin of the adjustment limit pin 434 realign with the slot on the linkage sleeve 435, and then the pulling force on the linkage sleeve 435 is cancelled, and the fin on the elastic telescopic support rod 436 is re-connected to the inside of the slot on the linkage sleeve 435 under the action of the elastic force of the elastic telescopic support rod 436 itself. At this time, the linkage sleeve 435 resumes the transmission between the rotating ring 432, and then the mounting sliding seat 33 is driven to move upward on the door-shaped sliding frame 31 by reversing the adjusting screw 32, and at the same time, the two adjusting sliders 423 are restored to their original positions, and the support block 425 cancels the thrust on the bottom plate 52. Since the limit slide rod 51 and the bottom plate 52 are elastically slidably connected, the bottom plate 52 is restored to its original position under the action of the elastic force, and the movable base 1 returns to the ground.

[0066] When the mounting sliding seat 33 moves upward, the mounting sliding seat 33 no longer generates tension on the pull rope 611. Since the sample connecting plate 62 and the movable base 1 are elastically slidably connected, under the action of the elastic force and in combination with the elasticity of the elastic telescopic connecting rod 612, the sample connecting plate 62 gradually slides to the right and contacts the outer circumferential surface of the coring drill bit 36. As the coring drill bit 36 ​​continues to move upward, when the coring drill bit 36 ​​moves to the top of the sample connecting plate 62, the sample connecting plate 62 continues to slide to the right under the coring drill bit 36 ​​to receive the sample brought out from the inside of the coring drill bit 36, and at the same time prevents the sample inside the coring drill bit 36 ​​from falling back into the coring position after the coring drill bit 36 ​​leaves the coring position.

[0067] like Fig.11 As shown, taking the knocking member 24 at the rear side as an example, the knocking member 24 includes a connecting frame 241 fixedly connected to the left side of the speed change gear box 223, the front end of the connecting frame 241 is fixedly connected to a mounting frame 244, the right side of the mounting frame 244 is rotatably connected to a turntable 243, the turntable 243 and the speed change gear box 223 are connected through a transmission shaft (not shown in the figure), a plurality of shifting blades 242 are evenly distributed on the circumferential surface of the turntable 243, and the right side of the turntable 243 is also rotatably connected to a mounting frame 244. The mounting frame 244 on the right is fixedly connected to the left side of the speed change gear box 223, and a hinge shaft 245 is rotatably connected between the opposite surfaces of the two mounting frames 244 and located below the turntable 243. A volute spring is arranged between the hinge shaft 245 and the mounting frame 244. A knocking hammer 246 is fixedly installed on the hinge shaft 245, and a knocking ball is arranged at the bottom end of the knocking hammer 246. The knocking hammer 246 and the hinge shaft 245 are kept relatively fixed by a limiting bolt (not shown in the figure).

[0068] Under normal conditions, when the turntable 243 remains stationary, the moving blade 242 generates a thrust on the top end of the striking hammer 246 away from the turntable 243, so that the bottom end of the striking hammer 246 is at the closest position to the turntable 243, so that the striking ball at the bottom end of the striking hammer 246 does not contact the outer circumferential surface of the coring drill bit 36 ​​during the downward movement and coring process of the coring drill bit 36.

[0069] When the sliding seat 33 is installed and moved upward, since the elastic strength between the connecting vertical rod 212 and the connecting support plate 211 is less than the elastic strength of the return spring on the sliding guide rod 222, when the sliding seat 33 is installed and moved upward, the connecting support plate 211 first slides upward on the circumferential surface of the connecting vertical rod 212. When there is no sliding distance between the connecting support plate 211 and the connecting vertical rod 212, the sample plate 62 is located below the coring drill bit 36. The upward pulling force generated by the connecting support plate 211 on the connecting vertical rod 212 by the installing sliding seat 33 acts on the tooth plate 221 through the bayonet 225, pulling the tooth plate 221 to move upward on the speed change gear box 223, and the gear transmission inside the speed change gear box 223 (not shown in the figure) drives the turntable 243 to rotate on the mounting frame 244. The speed change of the speed change gear box 223 makes the rotation frequency of the turntable 243 higher.

[0070] When the turntable 243 rotates on the mounting frame 244, it drives the multiple toggling blades 242 thereon to pass the top of the striking hammer 246 in sequence. When the toggling blade 242 passes the top of the striking hammer 246, it generates a forward thrust on the striking hammer 246, which pushes the striking hammer 246 to drive the hinge shaft 245 to rotate on the mounting frame 244. At this time, the scroll spring between the hinge shaft 245 and the mounting frame 244 is contracted. When the toggling blade 242 moves away from the striking hammer 246, the striking hammer 246 is quickly reset under the elastic force of the scroll spring itself. At this time, the striking hammer 246 is The knocking ball at the bottom of 46 knocks on the outer wall of the coring drill bit 36, and this cycle causes the knocking hammer 246 to intermittently knock on the outer wall of the coring drill bit 36, and as the coring drill bit 36 ​​continues to rise, the knocking hammer 246 can knock on different positions of the outer wall of the coring drill bit 36, so that the sample inside the coring drill bit 36 ​​quickly detaches from the inside of the coring drill bit 36 ​​and falls onto the sample receiving plate 62. The staff takes the sample away, then pushes the mobile base 1 to the next coring position, and repeats the above steps to perform coring work at another coring position.

[0071] Working principle: During specific use, first select the sampling position, then rotate the adjusting screw 32 to drive the mounting sliding seat 33 to slide downward on the gate-shaped sliding frame 31, and drive the coring drill bit 36 ​​to approach the sampling position. At the same time, the adjusting screw 32 actively drives the bidirectional screw 422 through the control member 43, and drives the two adjusting slide blocks 423 to move in the direction of approaching each other, and pushes the support block 425 to approach the bottom plate 52 through the connecting strut 424, and pushes the bottom plate 52 to move downward. When the bottom plate 52 contacts the ground, as the adjusting screw 32 continues to rotate, the movable base 1 is gradually lifted upward, so that the device remains stable at the sampling position. At this time, the adjusting control member 43 cancels the linkage between the adjusting screw 32 and the bidirectional screw 422. At this time, the adjusting screw 32 continues to rotate the bidirectional screw 422 to remain stationary, and then the adjusting screw 32 continues to rotate to push the coring drill bit 36 ​​to the sampling position.

[0072] When the installation sliding seat 33 moves downward, the installation sliding seat 33 drives the connecting plate 62 to move away from the coring drill bit 36 ​​through the transmission member 61. When the bottom end of the coring drill bit 36 ​​moves close to the coring position, the engine is started and the coring drill bit 36 ​​starts to rotate through the belt and the transmission unit 35. At this time, the adjusting screw 32 is continued to be rotated to start the coring work. After the coring work is completed, the coring drill bit 36 ​​is driven to move upward by reversing the adjusting screw 32. At this time, the transmission member 61 cancels the pulling force of the connecting plate 62, and under the action of the elastic force, the connecting plate 62 is pressed against the outer wall of the coring drill bit 36 ​​as the coring drill bit 36 ​​continues to move upward.

[0073] When the coring drill bit 36 ​​slides upward to the top of the sample receiving plate 62, the sample receiving plate 62 moves to the bottom of the coring drill bit 36. At the same time, the knocking mechanism 2 starts to knock on the outer wall of the coring drill bit 36, and the auxiliary coring sample falls off from the inside of the coring drill bit 36 ​​and falls on the top of the sample receiving plate 62. At the same time, when the adjusting screw 32 is reversed, the support member 42 no longer generates thrust on the bottom plate 52. At this time, the bottom plate 52 gradually moves away from the ground as the support member 42 is retracted, and the mobile base 1 falls to the ground again. When the staff takes away the sample on the sample receiving plate 62, the mobile base 1 is pushed to the next sampling position, and the above steps are repeated to perform sampling again.
