Description

Technical Field

[0001] The present invention relates to the technical field of road drilling and sampling, and particularly to a drilling and sampling device for road construction inspection. Background Art

[0002] In the process of road engineering construction and later maintenance, the quality inspection of the road structure layer is a key link to ensure the safe and stable operation of the road. Among them, drilling and sampling is a common and important inspection method. By drilling and taking soil at different depths and positions of the road, soil components, density and other indicators are analyzed to evaluate the bearing capacity and stability of the road foundation.

[0003] There are many deficiencies in the traditional road construction inspection drilling and sampling method. Among them, after the drilling and sampling are completed, the holes for sampling cannot be automatically sealed. With the frequent passage of vehicles, external moisture and sundries are likely to enter the road structure through the unsealed holes, which will affect the strength and stability of the road base material, shorten the service life of the road, and even may cause safety hazards such as road surface collapse.

[0004] During the sampling process, how to ensure the originality of the taken soil is also a technical problem to be solved urgently. When the traditional sampling device takes out the soil sample, it is easily polluted by the external environment. For example, during the demolding process, the soil sample may have phenomena such as particle breakage and mixing between different soil layers. This pollution of the soil sample will not only affect the accuracy of the subsequent test results and cannot truly reflect the actual condition of the road, but also may lead to unreasonable road maintenance decisions based on incorrect data, increasing the road maintenance cost and risk.

[0005] Therefore, the present invention provides a drilling and sampling device for road construction inspection to solve the above problems. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a drilling and sampling device for road construction inspection to solve the problems that can automatically seal the holes after sampling, avoid affecting the normal use of the road, and at the same time can ensure the originality of the soil and automatically demold.

[0007] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows: A punching and sampling device for road construction inspection, comprising a fixed column and a bottom plate. The fixed column is fixedly installed on one side of the top of the bottom plate. A main slide plate is slidably connected to the inner wall of the fixed column. The main slide plate is drivingly connected to a driving motor. One end of the main slide plate is rotatably connected to a sampling cylinder. An inner arc plate is slidably connected to the inside of the sampling cylinder. The sampling cylinder is drivingly connected to the driving motor. Left and right fixing plates are respectively fixedly installed on both sides of the main slide plate. A sliding box is slidably connected to the inside of the left fixing plate. The sliding box is drivingly connected to the main slide plate. The sliding box is matched with the sampling cylinder. A sliding toothed plate is slidably connected to the inside of the right fixing plate. The sliding toothed plate is drivingly connected to the main slide plate. The sliding toothed plate is matched with the inner arc plate. A filling box is fixedly installed on the top of the bottom plate. The filling box is matched with the bottom of the sampling cylinder; through the settings of the driving motor and the main slide plate, this device can automatically drive the device to punch and sample, realizing automatic operation. Through the settings of the sliding box and the filling box, after the sampling is completed, the device can automatically cut the lower part of the sample, and at the same time, the filling box fills the holes punched for sampling with materials for plugging, and then covers the cut lower part, achieving the effect of automatic sealing, avoiding phenomena such as road collapse, ensuring the service life of the road. At the same time, the sliding toothed plate of this device can demold the sampling cylinder after sampling, realizing automatic separation of the sample after automatic sampling, preventing the phenomenon of human interference, and ensuring the original state of the sample.

[0008] Preferably, a chute is opened on the side wall of the fixed column. A bidirectional lead screw is rotatably connected to the inside of the chute. The bidirectional lead screw is fixedly connected to the output end of the driving motor. A threaded block is threadedly connected to the outer wall of the bidirectional lead screw. One end of the threaded block is fixedly connected to one end of the main slide plate; a telescopic rotating shaft is rotatably connected to the top of the main slide plate. The telescopic end at the top of the telescopic rotating shaft is fixedly connected to the output end of the driving motor through a transmission belt. A main rotating gear is fixedly installed on the outer wall of the fixed end at the bottom of the telescopic rotating shaft. An outer ring gear is arranged on the outer wall of the upper part of the sampling cylinder. The outer ring gear is meshed with the main rotating gear; when this device is in use, by starting the driving motor, the driving motor drives the bidirectional lead screw to rotate, at this time, the main slide plate is driven to move downward to realize the sampling of the sampling cylinder. At the same time, when the driving motor rotates, the sampling cylinder will be driven to rotate for sampling.

[0009] Preferably, a fixed toothed plate is slidably connected to the side wall of the left fixed plate, and friction lines are provided on the side wall of the fixed toothed plate; a connecting shaft is rotatably connected to the inside of the sliding box, a driving gear is unidirectionally driven and connected to the outer wall of the connecting shaft, the driving gear is matched with the fixed toothed plate, a descending spring is fixedly installed on the side wall of the sliding box, and the top of the descending spring is fixedly connected to the bottom of the left fixed plate; a cutting box is installed at the bottom of the sliding box, a driving lead screw is rotatably connected to the inside of the cutting box, the driving lead screw is drivingly connected to the connecting shaft through a driving belt, a right-angled threaded plate is threadedly connected to the outer wall of the driving lead screw, and a cutting disc is clamped to the outer wall of the right-angled threaded plate through a block and a slot; when the device takes a sample, the descending of the main sliding plate will synchronously drive the left fixed plate to descend. At this time, the cutting box will abut against the upper surface of the bottom plate, the cutting box drives the sliding box to move upward, the descending spring is in a compressed state, and at the same time the fixed toothed plate moves upward synchronously. When the sampling is completed, due to the effect of the friction lines on the outer wall of the fixed toothed plate, the reset of the fixed toothed plate is relatively slow at this time, while the sliding box quickly resets under the action of the descending spring. At this time, for the sliding box to complete the reset, the fixed toothed plate slowly resets. When the sliding box descends, since the driving gear is unidirectionally driven and connected, it will not drive the connecting shaft to rotate. When the fixed toothed plate resets, the driving gear drives the connecting shaft to rotate at this time, realizing the outward cutting of the cutting disc; the reset times of the sliding box and the fixed toothed plate of the device are staggered to ensure that they are reset one after the other, so that cutting can be carried out only after the cutting disc is aligned with the position. At the same time, the displacement of the cutting disc of the device can form a linkage function with the main sliding plate, and at the same time avoid functional conflicts. Only when the main sliding plate resets, it will drive the cutting disc to extend and cut, realizing the linkage effect between functions.

[0010] Preferably, a separating plate is slidably connected to the inner wall of the bottom of the cutting disc, the front end of the separating plate is provided with an inclined surface, and a separating spring is fixedly installed on the top of the separating plate, and the top of the separating spring is fixedly connected to the inner top wall of the cutting disc.

[0011] Preferably, a cutting groove is formed on the outer wall of the bottom of the sampling cylinder. The cutting groove is matched with the cutting disc. A cutting template is clamped at the top of the sampling cylinder. A stretching block is fixedly installed at the top of the inner arc plate. The stretching block is a right-angle plate. A clamping groove is formed on the inner side wall of the bottom of the inner arc plate. The clamping groove is matched with the cutting disc. When sampling with this device, the descending depth is large. After sampling, the transmission belt is detached, the sampling cylinder stops rotating, the cutting groove faces the cutting disc, and the cutting disc cuts the bottom of the sample through the cutting groove. When the cutting disc completely enters the sampling cylinder, the cutting disc is clamped with the clamping groove at this time. When the cutting disc moves upward, the clamping block and the clamping groove are easy to disengage from the clamping connection. At the same time, the separating plate descends to press against the sample at the lower part of the sample to block the hole. When sampling with this device, the descending depth of the sampling cylinder is more than the expected depth to meet two requirements. One is to facilitate the cutting of the bottom of the sample to block the bottom of the sample, and the other is to block the hole for sampling by drilling to avoid the phenomenon of road damage. At the same time, the cutting of this device can be carried out automatically. This device can vertically cut the sample through the cutting template to avoid the phenomenon of data error caused by the pollution of the outer wall of the sample. By cutting the middle part of the sample with the cutting template, the condition between different layers of the sample is restored.

[0012] Preferably, a telescopic rod is slidably connected to the inner side wall of the right fixing plate. The bottom of one end of the telescopic rod is arc-shaped. A limiting plate is fixedly installed on the side wall of the bottom of the sliding tooth plate. The limiting plate is matched with the telescopic rod. A compression spring is fixedly installed on the side wall of the sliding tooth plate. The top of the compression spring is fixedly connected to the bottom of the right fixing plate. An abutting top plate is slidably connected to one end inside the right fixing plate. The abutting top plate faces the sliding tooth plate. A sliding shaft is rotatably connected to the inner side wall inside the right fixing plate. A sliding gear is installed on the outer wall of the sliding shaft. The sliding gear is located between the abutting top plate and the sliding tooth plate. In the initial state of this device, the sliding gear is not meshed with the abutting top plate and the sliding tooth plate. When the main sliding plate descends for sampling, at this time, the sliding tooth plate and the abutting top plate move upward. After rising, the limiting plate is clamped with the telescopic rod to limit the reset of the sliding tooth plate. The compression spring is a strong spring and is in a compressed state at this time. The abutting top plate resets to the initial position. When an action is required, at this time, by sliding the sliding shaft, the sliding gear forms a meshing connection between the sliding tooth plate and the abutting top plate. The descending of the sliding tooth plate can drive the abutting top plate to move upward.

[0013] Preferably, a shrinkage plate is slidably connected inside the abutting top plate, and an abutting groove is formed inside the shrinkage plate; an upper top plate is slidably connected to the inner wall of the abutting top plate, and an abutting inclined block is fixedly installed on the side wall of the upper top plate. The abutting inclined block is matched with the abutting groove, and the width of the abutting inclined block increases sequentially from top to bottom. An abutting spring is fixedly installed on the top of the upper top plate, and the top of the abutting spring is fixedly connected to the inner bottom wall of the abutting top plate. The shrinkage plate is matched with the stretching block; when the abutting top plate of this device receives the abutting force from the bottom plate, at this time, the upper top plate moves upward, and the width of the abutting inclined block abutting against the abutting groove becomes larger, thereby causing the shrinkage plate to retract. The bottom of the outer wall of the shrinkage plate of this device is set as an arc surface. Therefore, when the abutting top plate moves upward, the shrinkage plate is in a shrunk state and will not cause the shrinkage plate to abut against the stretching block. After resetting, the bottom of the abutting top plate loses the abutting force, and the shrinkage plate extends. When the sliding tooth plate drives the abutting top plate to move upward, the straight surface of the shrinkage plate abuts against the straight surface of the bottom of the stretching block, causing the abutting top plate to drive the inner arc plate to move upward, realizing the demoulding function. At the same time, the cutting template of this device is detachable and can be installed and disassembled as required; the sliding tooth plate and the abutting top plate of this device can form a linkage with the main slide plate to realize the function of automatic demoulding and avoid human contact. When sampling with this device, the phenomenon of demoulding of the abutting top plate will not occur. Only after sampling is completed can automatic demoulding be carried out to avoid the phenomenon that they cannot be used with each other.

[0014] Preferably, a feed box is slidably connected inside the filling box. One end of the feed box is provided with a discharge cylinder, and the discharge cylinder is matched with the sampling cylinder. The other end of the feed box is fixedly installed with a return spring, and the other end of the return spring is fixedly connected to the inner side wall of the filling box. The top wall of the feed box is provided with a feed inlet, and a feed cylinder is installed on the top of the filling box. The feed cylinder is matched with the feed inlet; in the initial state of this device, the discharge cylinder abuts against the sampling cylinder, the feed box moves backward, the feed inlet and the feed cylinder are arranged in a staggered manner, and the filling material inside the feed cylinder cannot be filled. After the sampling cylinder is reset and resets more, at this time, the discharge cylinder extends under the action of the return spring, the feed inlet and the feed cylinder are opposite to each other, so that the filling material flows out of the feed cylinder to seal the drilled hole and cover the material cut by the cutting disc, enabling this device to automatically fill the hole.

[0015] The beneficial effects of the present invention are as follows: 1. Through the settings of the driving motor and the main slide plate, this device can automatically drive the device to perform punching and sampling, achieving automated operation. Through the settings of the sliding box and the filling box, after the sampling of this device is completed, it can automatically cut the lowest part of the sample. At the same time, the filling box fills the holes made during sampling with materials for plugging, and then covers the lowest part after cutting, achieving the effect of automatic sealing, avoiding phenomena such as road collapse, ensuring the service life of the road. At the same time, the sliding tooth plate of this device can demold the sampling cylinder after sampling, realizing automatic separation of the sample after automatic sampling, preventing the phenomenon of human interference, and ensuring the original state of the sample.

[0016] 2. The reset time of the sliding box and the fixed tooth plate of this device is staggered to ensure that they are reset one after the other, so that cutting can be carried out only after the cutting disc is aligned. At the same time, the displacement of the cutting disc of this device can form a linkage function with the main slide plate, and at the same time avoid functional conflicts. Only when the main slide plate is reset, will it drive the cutting disc to extend for cutting, realizing the linkage effect between functions.

[0017] 3. When this device samples, the descending depth of the sampling cylinder is more than the expected depth to meet two requirements. One is to facilitate the cutting of the bottom of the sample to plug the bottom of the sample, and on the other hand, it can plug the holes made by punching and sampling to avoid road damage. At the same time, the cutting of this device can be carried out automatically. This device can vertically cut the sample through the cutting template to avoid the phenomenon of data errors caused by pollution on the outer wall of the sample. By cutting the middle part of the sample with the cutting template, the conditions between different layers of the sample are restored.

[0018] 4. The sliding tooth plate and the abutting top plate of this device can form a linkage with the main slide plate to realize the function of automatic demolding and avoid human contact. When this device samples, it will not cause the phenomenon of the abutting top plate for demolding. Only after the sampling is completed can it be automatically demolded to avoid the phenomenon of mutual inoperability.

[0019] 5. In the initial state of this device, the discharge cylinder abuts against the sampling cylinder, the feeding box moves backward, the feeding port and the feeding cylinder are arranged in a staggered manner, and the filling material inside the feeding cylinder cannot be filled. After the sampling cylinder is reset and resets more, at this time, the discharge cylinder extends under the action of the reset spring, the feeding port and the feeding cylinder are opposite, so that the filling material flows out of the feeding cylinder to seal the drilled holes and cover the materials cut by the cutting disc, enabling this device to automatically fill the holes.

Detailed implementation manners

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0023] A drilling and sampling device for road construction inspection, as shown in the attached Figure 1-2 figure, includes a fixed column 1 and a bottom plate 2. The fixed column 1 is fixedly installed on one side of the top of the bottom plate 2. A main slide plate 3 is slidably connected to the inner wall of the fixed column 1. The main slide plate 3 is drivingly connected to a driving motor 10. One end of the main slide plate 3 is rotatably connected to a sampling cylinder 4. An inner arc plate 401 is slidably connected to the inside of the sampling cylinder 4. The sampling cylinder 4 is drivingly connected to the driving motor 10. Left and right fixing plates 5 and 6 are respectively fixedly installed on both sides of the main slide plate 3. A sliding box 7 is slidably connected to the inside of the left fixing plate 5. The sliding box 7 is drivingly connected to the main slide plate 3. The sliding box 7 is matched with the sampling cylinder 4. A sliding toothed plate 8 is slidably connected to the inside of the right fixing plate 6. The sliding toothed plate 8 is drivingly connected to the main slide plate 3. The sliding toothed plate 8 is matched with the inner arc plate 401. A filling box 9 is fixedly installed on the top of the bottom plate 2. The filling box 9 is matched with the bottom of the sampling cylinder 4. Through the settings of the driving motor 10 and the main slide plate 3, this device can automatically drive the device to perform drilling and sampling, realizing automated operation. Through the settings of the sliding box 7 and the filling box 9, after the sampling of this device is completed, it can automatically cut the lower part of the sample, and at the same time, the filling box 9 fills the holes drilled for sampling with materials for plugging, and then covers the cut lower part, achieving the effect of automatic sealing, avoiding phenomena such as road collapse, ensuring the service life of the road. At the same time, the sliding toothed plate 8 of this device can demold the sampling cylinder 4 after sampling, realizing automatic separation of the sample after automatic sampling, preventing the phenomenon of human interference, and ensuring the original state of the sample.

[0024] As shown in the attached Figure 1 figure, a chute 101 is opened on the side wall of the fixed column 1. A bidirectional lead screw 102 is rotatably connected to the inside of the chute 101. The bidirectional lead screw 102 is fixedly connected to the output end of the driving motor 10. A threaded block is threadedly connected to the outer wall of the bidirectional lead screw 102. One end of the threaded block is fixedly connected to one end of the main slide plate 3. A telescopic rotating shaft 301 is rotatably connected to the top of the main slide plate 3. The telescopic end at the top of the telescopic rotating shaft 301 is fixedly connected to the output end of the driving motor 10 through a transmission belt 302. A main rotating gear 303 is fixedly installed on the outer wall of the fixed end at the bottom of the telescopic rotating shaft 301. An outer ring gear 402 is provided on the outer wall of the upper part of the sampling cylinder 4. The outer ring gear 402 is meshed with the main rotating gear 303. When this device is in use, by starting the driving motor 10, the driving motor 10 drives the bidirectional lead screw 102 to rotate. At this time, the main slide plate 3 is driven to move downward to realize the sampling of the sampling cylinder 4. At the same time, when the driving motor 10 rotates, the sampling cylinder 4 will be synchronously driven to rotate for sampling.

[0025] As shown in the attached Figure 2-3 figure, a fixed tooth plate 701 is slidably connected to the side wall of the left fixed plate 5, and friction lines are provided on the side wall of the fixed tooth plate 701; a connecting shaft 702 is rotatably connected to the inside of the sliding box 7, and a driving gear 704 is unidirectionally drivingly connected to the outer wall of the connecting shaft 702. The driving gear 704 is matched with the fixed tooth plate 701. A descending spring 703 is fixedly installed on the side wall of the sliding box 7, and the top of the descending spring 703 is fixedly connected to the bottom of the left fixed plate 5; a cutting box 705 is installed at the bottom of the sliding box 7, and a driving lead screw 706 is rotatably connected to the inside of the cutting box 705. The driving lead screw 706 is drivingly connected to the connecting shaft 702 through a driving belt 707. A right-angled threaded plate 708 is threadedly connected to the outer wall of the driving lead screw 706, and a cutting disc 709 is clamped to the outer wall of the right-angled threaded plate 708 through a clamping block 710 and a clamping groove 711; when the device samples, the descending of the main sliding plate 3 will synchronously drive the left fixed plate 5 to descend. At this time, the cutting box 705 will abut against the upper surface of the bottom plate 2, and the cutting box 705 will drive the sliding box 7 to move upward. The descending spring 703 is in a compressed state, and at the same time, the fixed tooth plate 701 will synchronously move upward. When the sampling is completed, due to the function of the friction lines on the outer wall of the fixed tooth plate, the reset of the fixed tooth plate is relatively slow at this time, while the sliding box 7 quickly resets under the action of the descending spring 703. At this time, when the reset of the sliding box 7 is completed, the fixed tooth plate 701 slowly resets. When the sliding box 7 descends, since the driving gear 704 is unidirectionally drivingly connected, it will not drive the connecting shaft 702 to rotate. When the fixed tooth plate 701 resets, at this time, the driving gear 704 drives the connecting shaft 702 to rotate, realizing the outward cutting of the cutting disc 709; the reset time of the sliding box 7 and the fixed tooth plate 701 of the device is staggered to ensure that they reset one after the other, so that cutting can be carried out only after the cutting disc 709 is aligned. At the same time, the displacement of the cutting disc 709 of the device can form a linkage function with the main sliding plate 3, and at the same time, functional conflicts are avoided. Only when the main sliding plate 3 resets, will it drive the cutting disc 709 to extend and cut, realizing the linkage effect between functions.

[0026] As shown in the attached Figure 4 figure, a separating plate 712 is slidably connected to the inner wall of the bottom of the cutting disc 709. The front end of the separating plate 712 is provided with an inclined surface, and a separating spring 713 is fixedly installed on the top of the separating plate 712. The top of the separating spring 713 is fixedly connected to the inner top wall of the cutting disc 709.

[0027] As shown in the attached Figure 5-6As shown in the figure, a cutting groove 403 is provided on the outer wall of the bottom of the sampling cylinder 4. The cutting groove 403 is matched with the cutting disc 709. A cutting template 404 is clamped at the top of the sampling cylinder 4. A stretching block 405 is fixedly installed at the top of the inner arc plate 401. The stretching block 405 is a right-angled plate. A clamping groove 406 is provided on the inner side wall of the bottom of the inner arc plate 401. The clamping groove 406 is matched with the cutting disc 709. When sampling with this device, the descending depth is large. After sampling, the transmission belt 302 is detached and the sampling cylinder 4 stops rotating. The cutting groove 403 is opposite to the cutting disc 709. The cutting disc 709 cuts the bottom of the sample through the cutting groove 403. When the cutting disc 709 completely enters the sampling cylinder 4, at this time, the cutting disc 709 is clamped with the clamping groove 406. When the cutting disc 709 moves upward, the clamping block 710 and the clamping groove 711 are easily disengaged from the clamping connection. At the same time, the disengaging plate 712 descends to block the sample at the lower part of the sample against the hole. When sampling with this device, the descending depth of the sampling cylinder 4 is more than the expected depth to meet two requirements. One is to facilitate the cutting of the bottom of the sample to block the bottom of the sample, and the other is to block the hole for sampling by drilling to avoid the phenomenon of road damage. At the same time, the cutting of this device can be carried out automatically. This device can vertically cut the sample through the cutting template 404 to avoid the phenomenon of data error caused by the pollution of the outer wall of the sample. By cutting the middle part of the sample through the cutting template 404, the condition between different layers of the sample is restored.

[0028] As shown in the Figure 7-9 figure, a telescopic rod 601 is slidably connected to the inner side wall of the right fixing plate 6. The bottom of one end of the telescopic rod 601 is arc-shaped. A limiting plate 801 is fixedly installed on the side wall of the bottom of the sliding tooth plate 8. The limiting plate 801 is matched with the telescopic rod 601. A compression spring 802 is fixedly installed on the side wall of the sliding tooth plate 8. The top of the compression spring 802 is fixedly connected to the bottom of the right fixing plate 6. One end inside the right fixing plate 6 is slidably connected with a top pressing plate 803. The top pressing plate 803 is opposite to the sliding tooth plate 8. A sliding shaft 602 is rotatably connected to the inner side wall of the right fixing plate 6. A sliding gear 603 is installed on the outer wall of the sliding shaft 602. The sliding gear 603 is located between the top pressing plate 803 and the sliding tooth plate 8. In the initial state of this device, the sliding gear 603 is not meshed with the top pressing plate 803 and the sliding tooth plate 8. When the main sliding plate 3 descends for sampling, at this time, the sliding tooth plate 8 and the top pressing plate 803 move upward. After rising, the limiting plate 801 is clamped with the telescopic rod 601 to limit the reset of the sliding tooth plate 8. The compression spring 802 is a strong spring and is in a compressed state at this time. The top pressing plate 803 resets to the initial position. When action is required, at this time, by sliding the sliding shaft 602, the sliding gear 603 forms a meshing connection between the sliding tooth plate 8 and the top pressing plate 803. The descent of the sliding tooth plate 8 can drive the top pressing plate 803 to move upward.

[0029] As shown in the Figure 10As shown in the figure, a retractable plate 804 is slidably connected inside the top support plate 803, and a jacking groove 805 is formed inside the retractable plate 804; a top plate 806 is slidably connected to the inner wall of the top support plate 803, and a jacking inclined block 807 is fixedly installed on the side wall of the top plate 806. The jacking inclined block 807 is matched with the jacking groove 805, and the width of the jacking inclined block 807 increases successively from top to bottom. A jacking spring 808 is fixedly installed on the top of the top plate 806, and the top of the jacking spring 808 is fixedly connected to the inner bottom wall of the top support plate 803. The retractable plate 804 is matched with the stretching block 405; when the top support plate 803 of this device receives the jacking force from the bottom plate 2, at this time, the top plate 806 moves upward, and the width of the contact between the jacking inclined block 807 and the jacking groove 805 becomes larger, thereby causing the retractable plate 804 to retract. The bottom of the outer wall of the retractable plate 804 of this device is set as an arc surface. Therefore, when the top support plate 803 moves upward, the retractable plate 804 is in a retracted state, and it will not cause the retractable plate 804 to be in contact with the stretching block 405. After resetting, the bottom of the top support plate 803 loses the jacking force, and the retractable plate 804 extends. When the sliding tooth plate 8 drives the top support plate 803 to move upward, the straight surface of the retractable plate 804 contacts the straight surface at the bottom of the stretching block 405, causing the top support plate 803 to drive the inner arc plate 401 to move upward, realizing the demolding function. At the same time, the cutting template 404 of this device is detachable and can be installed and disassembled as required; the sliding tooth plate 8 and the top support plate 803 of this device can form a linkage with the main sliding plate 3 to realize the function of automatic demolding and avoid manual contact. When sampling with this device, the phenomenon of demolding of the top support plate 803 will not occur. Only after sampling is completed can it be automatically demolded to avoid the phenomenon that they cannot be used with each other.

[0030] As shown in the attachment Figure 11 As shown in the figure, a feeding box 901 is slidably connected inside the filling box 9. One end of the feeding box 901 is provided with a discharge tube 902, and the discharge tube 902 is matched with the sampling tube 4. The other end of the feeding box 901 is fixedly installed with a return spring 905, and the other end of the return spring 905 is fixedly connected to the inner side wall of the filling box 9. The top wall of the feeding box 901 is provided with a feeding port 903, and a feeding tube 904 is installed on the top of the filling box 9. The feeding tube 904 is matched with the feeding port 903; in the initial state of this device, the discharge tube 902 contacts the sampling tube 4, the feeding box 901 moves backward, and the feeding port 903 and the feeding tube 904 are misaligned. The filling material inside the feeding tube 904 cannot be filled. After the sampling tube 4 is reset and has a large amount of reset, at this time, the discharge tube 902 extends under the action of the return spring 905, and the feeding port 903 is opposite to the feeding tube 904, causing the filling material to flow out of the feeding tube 904 to seal the drilled hole and cover the material cut by the cutting disc 709, enabling this device to automatically fill the hole.
