[0004] The insulation mortar coring machines currently on the market still have the following problems: when sampling, due to the generally poor building environment and insufficient ground flatness, it is easy for the drill bit and the wall to not remain level, resulting in the sample being taken out as an inclined column. During operation, it is easy to cause mechanical risks and cause the drill bit to fall off. Therefore, it is necessary to design a coring machine that can remain perpendicular to the wall. Summary of the Invention

The rebound rod is fixed on the top surface of the mobile platform, one end of the connecting rod is fixed to the front end of the rebound rod, the positioning ring is fixed to the other end of the connecting rod, and the rubber baffle is fixed to the side of the flat plate. Before the flat plate is placed against the wall, the drilling position needs to be positioned to avoid deviation from the sampling point. When the flat plate is close to the wall, the flat plate squeezes the rebound rod, and the rebound rod drives the connecting rod close to the flat plate, and the connecting rod drives the positioning ring close to the flat plate, so that the drilling point is determined by using the positioning ring without affecting the function of the flat plate, thereby ensuring the accuracy of drilling sampling. At the same time, the rubber baffle arranged on the side of the flat plate can cover and protect the dust generated by drilling, thereby avoiding the health risks of dust to the operator.

When drilling and sampling are required, the horizontal telescopic rod is started, the horizontal telescopic rod pushes the push plate, the push plate pushes the motor, and the motor The special-shaped drill barrel is pushed and the motor is started at the same time. The motor drives the special-shaped drill barrel to rotate, and the insulation layer is cut and sampled by the propulsion and rotation of the special-shaped drill barrel. When the sampling is completed, the cylindrical sample needs to be taken out from the inside of the special-shaped drill barrel. At this time, the motor is turned off and the horizontal telescopic rod is started. The horizontal telescopic rod pulls back the push plate, the push plate pulls back the motor, and the motor pulls back the special-shaped drill barrel. Since the annular base is fixed, the long rod remains stationary relative to the special-shaped drill barrel, and the push ring remains stationary relative to the special-shaped drill barrel. The push ring is used to push the taken out sample out of the special-shaped drill barrel, making the sampling operation more convenient, reducing the sampling steps, and avoiding damage to the sample when taking it out from the inside of the special-shaped drill barrel.

[0009] According to the above technical solution, the drilling device also includes an arc-shaped piece, an arc-shaped cutting block, a fastening pressure rod and an elastic rod, the arc-shaped piece is slidably mounted on the outer wall of the special-shaped drill barrel, the back of the flat plate is located on the movement track of the arc-shaped piece, the tail end of the special-shaped drill barrel is provided with an arc-shaped through groove for the arc-shaped piece to pass through, the arc-shaped cutting block is slidably mounted on the inner wall of the tail end of the special-shaped drill barrel, the arc-shaped cutting block is located on the movement track of the arc-shaped piece, the fastening pressure rod is fixed on the inner side of the arc-shaped cutting block, the inner wall of the special-shaped drill barrel is provided with a long groove, the fastening pressure rod is slidably mounted in the long groove on the inner wall of the special-shaped drill barrel, one end of the elastic rod is fixed on the inner wall of the special-shaped drill barrel, and the other end of the elastic rod is fixed on the inner side of the arc-shaped cutting block. When the drilling reaches the required depth, if you want to take out the sample, you also need to put the thermal insulation mortar sample and the actual sample together. The special-shaped drill barrel is moved, and the special-shaped drill barrel drives the arc piece to move. When the arc piece moves the last distance, it will touch the back of the flat plate, and the arc piece will be squeezed to slide inside the tail end of the special-shaped drill barrel, and the arc piece pushes the arc cut block, and the arc cut block moves toward the center of the circle of the special-shaped drill barrel. The arc cut block drives the fastening pressure rod to move toward the center of the circle of the special-shaped drill barrel, so that the elastic rod contracts, and the fastening pressure rod is used to clamp and fix the drilled sample, and then the special-shaped drill barrel is used to drive the fastening pressure rod to rotate, so that the fastening pressure rod drives the sample to rotate, so as to achieve the purpose of separating the sample from the wall, and after pulling the moving platform backward, the fastening pressure rod will directly bring the sample out of the drill hole, thereby achieving the purpose of complete sampling, making sampling more convenient and saving subsequent operations.

[0010] According to the above technical solution, the cooling device includes a water tank, a screw, an extrusion plate, a hose, a spray ring and a wiper strip, the water tank is fixed on the top surface of the support plate, the screw is rotatably mounted on the back of the push plate, the screw passes through and is slidably mounted on the front of the water tank, the extrusion plate is rotatably mounted on the tail end of the screw, the extrusion plate is slidably mounted on the inner wall of the water tank, one end of the hose is fixed on the front of the water tank, the spray ring is fixed on the front of the flat plate, the other end of the hose is fixed on the back of the spray ring, a drainage groove is provided on the front of the flat plate, the wiper strip is fixed in the drainage groove on the front of the flat plate, and the water is removed from the water tank by drilling. Before hole sampling, add cooling water into the water tank. When the push plate pushes, the push plate drives the screw to move forward, and the screw drives the extrusion plate to move forward. The extrusion plate pushes the cooling water inside the water tank to drain, so that it reaches the spray ring through the hose, and the cooling water is sprayed through the spray ring, thereby cooling the surface of the special-shaped drill barrel, and also achieving the purpose of lubrication, avoiding the drill barrel from overheating and becoming brittle after long-term use, and also achieving a certain purpose of dust prevention. Then use the scraper strip to scrape and clean the outer wall of the special-shaped drill barrel, and clean and scrape off the wet wall powder to prevent it from clogging the channel and making it inconvenient to pull out the sample later.

[0011] According to the above technical solution, the cooling device also includes a filter, a propeller, a block and a water outlet pipe. The filter is fixed to the front of the inner wall of the water tank, the propeller is rotatably installed on the front of the inner wall of the water tank, the propeller is threadedly connected to the outer wall of the screw, the water outlet pipe passes through and is fixed to the side of the water tank, and the block is slidably installed at the water outlet of the water outlet pipe. A spring is provided between the block and the inner wall of the water tank. Since the automatic coring machine is used in an environment such as a construction site all year round, the cooling water used also contains a lot of impurities, which easily cause precipitation and siltation in the water tank, thereby causing the hose to be clogged. Therefore, the filter is used to isolate the impurities in the water tank. At the same time, during the movement of the screw, the screw drives the propeller to rotate, and the propeller is used to mix and disturb the water in the water tank, so that the impurities are evenly distributed in the water body. When the extrusion plate reaches the end, the extrusion plate pushes away the block, allowing the remaining cooling water to be discharged through the water outlet pipe. By not using the remaining cooling water with a high solubility in the final sediment, the purpose of avoiding hose clogging as much as possible is achieved, and the maintenance frequency of the cooling device is reduced.

[0012] According to the above technical solution, the anti-dumping device includes an annular bottom block, an L-shaped frame and a stud. The annular bottom block is slidably installed on the side of the mobile platform, the L-shaped frame is fixed on the top surface of the mobile platform, and the stud is rotatably installed on the top surface of the L-shaped frame. The annular bottom block is threadedly connected to the bottom end of the stud. When the drilling sampling point is determined, the stud is screwed to increase the distance between the annular bottom block and the L-shaped frame, so that the annular bottom block moves downward. The annular bottom block is used to increase the contact area between the entire device and the ground, thereby achieving the purpose of stabilizing the coring machine, avoiding the corer from deflecting or shaking during drilling, optimizing the operation that previously required manpower to resist the corer, and making the device more labor-saving and convenient.

[0013] According to the above technical solution, the anti-dumping device also includes a T-shaped bottom block and a slider, a distance-adjusting block, and an elastic column. Rectangular grooves are opened on both sides of the annular bottom block. The T-shaped bottom block is slidably installed on the inner wall of the rectangular groove. The slider is slidably installed on the top surface of the annular bottom block. The distance-adjusting block is fixed on the inner side of the slider. The distance-adjusting block is located on the movement track of the T-shaped bottom block. A spring is provided between the slider and the top surface of the annular bottom block. One end of the elastic column is fixed in the groove on the top surface of the annular bottom block, and the other end of the elastic column is fixed to the top of the T-shaped bottom block. Due to the poor building environment, on some grounds with sideways inclination or partial When the vehicle is in a depressed position, the T-shaped bottom block can be directly pressed, the elastic column contracts, the T-shaped bottom block squeezes the distance adjusting blocks to both sides, and the distance adjusting blocks drive the sliders to slide to both sides. When the bottom of the T-shaped bottom block contacts the ground at the depressed position, the slider rebounds inward under the action of the spring force, and the slider drives the distance adjusting block to rebound inward. The distance adjusting block is used to limit the upward rebound trajectory of the T-shaped bottom block, so as to achieve the purpose of reducing the contact point between the local bottom surface of the annular bottom block and the ground, increase the anti-dumping effect, and prevent the device from tilting sideways. When unlocking is required, the sliders are pushed to both sides, the elastic column rebounds upward, and the elastic column drives the T-shaped bottom block to move upward and reset.

[0014] The present invention provides an automatic coring machine for building material testing. It has the following beneficial effects: (1) The present invention uses the setting of a leveling device to make two vertical telescopic rods, a support plate and a flat plate cooperate. The two vertical telescopic rods are started and used to drive the support plate to rotate and adjust the direction, adjust the vertical state of the support plate and the wall surface, and use the flat plate to stick to the wall surface to observe and adjust whether the support plate reaches verticality, thereby achieving the purpose of vertical drilling sampling, avoiding the deviation of the core drill bit and the breakage of the drilling equipment; the rebound rod, connecting rod, positioning ring and rubber baffle are made to cooperate. When the flat plate approaches the wall, the flat plate squeezes the rebound rod, the rebound rod drives the connecting rod to approach the flat plate, and the connecting rod drives the positioning ring to approach the flat plate, so that the positioning ring is used to determine the drilling point without affecting the function of the flat plate, thereby ensuring the accuracy of drilling sampling. At the same time, the rubber baffle provided on the side of the flat plate can cover and protect the dust generated by drilling, thereby avoiding the health risk of dust to the operator.

[0015] (2) The present invention uses the arrangement of the drilling device to coordinate the horizontal telescopic rod, the push plate, the motor, the special-shaped drill barrel, the long rod and the push ring with the annular base. When the sampling is completed, the push plate pulls back the motor, and the motor pulls back the special-shaped drill barrel. Since the annular base is fixed, the long rod remains stationary relative to the special-shaped drill barrel, and the push ring remains stationary relative to the special-shaped drill barrel. The push ring is used to push the sample taken out into the special-shaped drill barrel, making the sampling operation more convenient, reducing the sampling steps, and avoiding damage to the sample when it is taken out from the special-shaped drill barrel; the arc-shaped sheet, arc-shaped block, and tightening pressure rod are fixed. Cooperating with the elastic rod, the arc-shaped piece pushes the arc-shaped cutting block, and the arc-shaped cutting block moves toward the center of the special-shaped drill barrel. The arc-shaped cutting block drives the fastening pressure rod to move toward the center of the special-shaped drill barrel, causing the elastic rod to contract. The fastening pressure rod is used to clamp and fix the drilled sample. When the special-shaped drill barrel is used to drive the fastening pressure rod to rotate, the fastening pressure rod drives the sample to rotate, thereby achieving the purpose of separating the sample from the wall. After pulling the mobile platform backward, the fastening pressure rod will directly bring the sample out of the drill hole, thereby achieving the purpose of complete sampling, making sampling more convenient and saving subsequent operations.

[0016] (3) The present invention uses the setting of the cooling device to make the water tank, screw, extrusion plate, hose, spray ring and scraper strip cooperate. The screw drives the extrusion plate to move forward, and the extrusion plate pushes the cooling water inside the water tank to drain, so that it reaches the spray ring through the hose, and the cooling water is sprayed out through the spray ring, thereby cooling the surface of the special-shaped drill barrel, and also achieving the purpose of lubrication, avoiding the drill barrel from overheating and becoming brittle after a long period of use, and also achieving a certain purpose of preventing dust. Then the scraper strip is used to scrape and clean the outer wall of the special-shaped drill barrel, and the wet wall powder is cleaned and scraped to prevent it The channel is blocked, making it inconvenient to pull out the sample later; the filter, propeller, block and outlet pipe are coordinated, and the filter is used to isolate the impurities in the water tank. During the movement of the screw, the screw drives the propeller to rotate, and the propeller is used to mix and disturb the water in the water tank, so that the impurities are evenly distributed in the water body. When the extrusion plate reaches the end, the extrusion plate pushes away the block, so that the remaining cooling water is discharged through the outlet pipe. By not using the remaining cooling water with a higher solubility in the final sediment, the purpose of avoiding hose blockage as much as possible is achieved, and the maintenance frequency of the cooling device is reduced.

[0017] (4) The present invention uses the setting of the anti-dumping device to make the annular bottom block, L-shaped frame and stud cooperate with each other. By screwing the stud, the distance between the annular bottom block and the L-shaped frame is increased, and the annular bottom block moves downward. The annular bottom block is used to increase the contact area between the device as a whole and the ground, thereby achieving the purpose of stabilizing the core drill, avoiding the core drill from deflecting or shaking during drilling, optimizing the operation that previously required manpower to resist the core drill, and making the device more labor-saving and convenient; the T-shaped bottom block is made to cooperate with the slider, the distance-adjusting block and the elastic column. By directly pressing the T-shaped bottom block, the elastic column shrinks, and the T-shaped bottom block squeezes the distance-adjusting block to both sides. The distance-adjusting block drives the slider to slide to both sides. When the bottom of the T-shaped bottom block contacts the ground in the depression, the slider rebounds inward under the action of the spring force, and the slider drives the distance-adjusting block to rebound inward. The distance-adjusting block is used to limit the upward trajectory of the T-shaped bottom block, thereby achieving the purpose of reducing the contact point between the local bottom surface of the annular bottom block and the ground, increasing the anti-dumping effect, and preventing the device from tilting sideways.

The rebound rod 24 is fixed to the top surface of the mobile platform 1. Before the flat plate 23 is against the wall, the drilling position needs to be positioned to avoid deviation from the sampling point. When the flat plate 23 approaches the wall, the flat plate 23 squeezes the rebound rod 24, and one end of the connecting rod 25 is fixed to the front end of the rebound rod 24. The rebound rod 24 drives the connecting rod 25 close to the flat plate 23, and the positioning ring 26 is fixed to the other end of the connecting rod 25. The connecting rod 25 drives the positioning ring 26 close to the flat plate 23, so that the drilling point is determined by using the positioning ring 26 without affecting the function of the flat plate 23, thereby ensuring the accuracy of drilling sampling.

The horizontal telescopic rod 31 is fixed to the inner wall of the protective cover on the top surface of the support plate 22. When drilling and sampling are needed, the horizontal telescopic rod 31 is started, the push plate 32 is fixed to the telescopic end of the horizontal telescopic rod 31, the horizontal telescopic rod 31 pushes the push plate 32, the motor 33 is fixed to the front of the push plate 32, the push plate 32 pushes the motor 33, the special-shaped drill barrel 34 is fixed to the output end of the motor 33, the motor 33 pushes the special-shaped drill barrel 34, and at the same time the motor 33 is started, the motor 33 drives the special-shaped drill barrel 34 to rotate, and the insulation layer is cut and sampled by the propulsion and rotation of the special-shaped drill barrel 34. The annular base 37 is fixed to the top surface of the support plate 22, and one end of the long rod 35 is fixed to the It is slidably mounted on the front of the annular base 37, and the middle part of the long rod 35 passes through and is slidably mounted on the back of the special-shaped drill barrel 34. The push ring 36 is fixed to the other end of the long rod 35. When sampling is completed, it is necessary to take out the cylindrical sample from the inside of the special-shaped drill barrel 34. At this time, the motor 33 is turned off and the horizontal telescopic rod 31 is started. The horizontal telescopic rod 31 pulls back the push plate 32, the push plate 32 pulls back the motor 33, and the motor 33 pulls back the special-shaped drill barrel 34. Since the annular base 37 is fixed, the long rod 35 remains stationary relative to the special-shaped drill barrel 34, and the push ring 36 remains stationary relative to the special-shaped drill barrel 34. The push ring 36 is used to push the taken out sample out of the inside of the special-shaped drill barrel 34, making the sampling operation more convenient, reducing the sampling steps, and avoiding damage to the sample when taking it out from the inside of the special-shaped drill barrel 34.

[0024] The drilling device 3 also includes an arc piece 38, an arc cutting block 39, a fastening pressure rod 310 and an elastic rod 311. The arc piece 38 is slidably mounted on the outer wall of the special-shaped drill barrel 34. When the drilling reaches the required depth, the thermal insulation mortar sample and the actual wall surface need to be separated if the sample is to be taken out. Therefore, when the special-shaped drill barrel 34 moves, the special-shaped drill barrel 34 drives the arc piece 38 to move, and the back of the flat plate 23 is located on the movement trajectory of the arc piece 38. The arc piece 38 will touch the back of the flat plate 23 when moving the last distance. An arc through groove is provided at the tail end of the special-shaped drill barrel 34 for the arc piece 38 to pass through. The arc piece 38 is squeezed to slide inside the tail end of the special-shaped drill barrel 34, and the arc cutting block 39 is slidably mounted on the inner wall of the tail end of the special-shaped drill barrel 34. The arc cutting block 39 is located on the movement trajectory of the arc piece 38.

[0025] When in use, before drilling and sampling, it is necessary to align the core drill bit vertically with the wall, push the mobile platform 1 to the front of the wall paved with thermal insulation mortar, start the two vertical telescopic rods 21, use the two vertical telescopic rods 21 to drive the support plate 22 to rotate and adjust the direction, adjust the vertical state of the support plate 22 and the wall, use the flat plate 23 to stick to the wall, observe and adjust whether the support plate 22 is vertical, so as to achieve the purpose of vertical drilling and sampling, avoid the core drill bit from deviating, and avoid the drilling equipment from breaking; before the flat plate 23 is stuck to the wall, it is necessary to align the core drill bit vertically with the wall, and avoid the core drill bit from being deviated. The drilling position is positioned to avoid deviation from the sampling point. When the flat plate 23 is close to the wall, the flat plate 23 squeezes the rebound rod 24, and the rebound rod 24 drives the connecting rod 25 close to the flat plate 23. The connecting rod 25 drives the positioning ring 26 close to the flat plate 23, so that the positioning ring 26 is used to determine the drilling point without affecting the function of the flat plate 23, thereby ensuring the accuracy of drilling sampling. At the same time, the rubber baffle 27 arranged on the side of the flat plate 23 can cover and protect the dust generated by drilling, thereby avoiding the health risks of dust to the operator.

[0026] The motor 33 is driven by the pull rod 31 to push the push plate 32, and the push plate 32 pushes the motor 33, which pushes the special-shaped drill tube 34. When the sampling is completed, the cylindrical sample needs to be taken out from the special-shaped drill tube 34. At this time, the motor 33 is turned off and the horizontal telescopic rod 31 is started. The horizontal telescopic rod 31 is pulled back to pull the push plate 32, and the push plate 32 is pulled back to pull the motor 33. The motor 33 is pulled back to pull the special-shaped drill tube 34. Because the annular base 37 is fixed, the long rod 35 remains stationary relative to the special-shaped drill tube 34, and the push ring 36 remains stationary relative to the special-shaped drill tube 34. The sample taken out is pushed out of the special-shaped drill tube 34 by the push ring 36, which makes the sampling operation more convenient, reduces the sampling steps, and avoids damage to the sample when taking it out from the special-shaped drill tube 34. In order to take out the sample, the thermal insulation mortar sample needs to be separated from the actual wall surface. Therefore, when the special-shaped drill tube 34 moves, the special-shaped drill tube 34 drives the arc piece 38 to move. When the arc piece 38 moves the last distance, it touches the back of the flat plate 23. The arc piece 38 is squeezed to slide inside the tail end of the special-shaped drill tube 34. The arc piece 38 pushes the arc cut block 39, and the arc cut block 39 moves toward the center of the circle of the special-shaped drill tube 34. The arc cut block 39 drives the fastening pressure rod 310 to move toward the special-shaped drill tube 34. The special-shaped drill barrel 34 moves in the direction of the center of the circle, causing the elastic rod 311 to contract, and the drilled sample is clamped and fixed by the fastening pressure rod 310. The special-shaped drill barrel 34 is used to drive the fastening pressure rod 310 to rotate, so that the fastening pressure rod 310 drives the sample to rotate, thereby achieving the purpose of separating the sample from the wall, and after pulling the mobile platform 1 backward, the fastening pressure rod 310 will directly bring the sample out of the drill hole, thereby achieving the purpose of complete sampling, making sampling more convenient and saving subsequent operations.

[0027] See also Figure 1-9 On the basis of the above embodiment, another embodiment of the present invention further includes a cooling device 4 and an anti-dumping device 5.

[0028] The cooling device 4 includes a water tank 41, a screw 42, an extrusion plate 43, a hose 44, a spray ring 45 and a wiper strip 46. The water tank 41 is fixed on the top surface of the support plate 22, the screw 42 is rotatably mounted on the back of the push plate 32, the screw 42 penetrates and is slidably mounted on the front of the water tank 41, the extrusion plate 43 is rotatably mounted on the tail end of the screw 42, the extrusion plate 43 is slidably mounted on the inner wall of the water tank 41, one end of the hose 44 is fixed on the front of the water tank 41, the spray ring 45 is fixed on the front of the flat plate 23, the other end of the hose 44 is fixed on the back of the spray ring 45, a drainage groove is opened on the front of the flat plate 23, and the wiper strip 46 is fixed in the drainage groove on the front of the flat plate 23. Before drilling and sampling Cooling water is added to the water tank 41. When the push plate 32 pushes, the push plate 32 drives the screw 42 to move forward, and the screw 42 drives the extrusion plate 43 to move forward. The extrusion plate 43 pushes the cooling water inside the water tank 41 to drain, so that it reaches the spray ring 45 through the hose 44, and the cooling water is sprayed through the spray ring 45, thereby cooling the surface of the special-shaped drill barrel 34, and also achieving the purpose of lubrication, avoiding the drill barrel from overheating and becoming brittle after long-term use, and also achieving a certain purpose of preventing dust. The scraper strip 46 is then used to scrape and clean the outer wall of the special-shaped drill barrel 34, and clean and scrape off the wet wall powder to prevent it from clogging the channel and making it inconvenient to pull out the sample later.

[0029] The cooling device 4 also includes a filter 47, a propeller 48, a block 49 and a water outlet pipe 410. The filter 47 is fixed to the front of the inner wall of the water tank 41, the propeller 48 is rotatably installed on the front of the inner wall of the water tank 41, the propeller 48 is threadedly connected to the outer wall of the screw 42, the water outlet pipe 410 passes through and is fixed to the side of the water tank 41, the block 49 is slidably installed on the water outlet of the water outlet pipe 410, and a spring is provided between the block 49 and the inner wall of the water tank 41. Since the automatic coring machine is used in a construction site and other environments all year round, a cooling device 410 is used. The water source also contains a lot of impurities, which can easily cause precipitation and siltation in the water tank 41, and then cause the hose 44 to be blocked. Therefore, the filter 47 is used to isolate the impurities in the water tank 41. At the same time, during the movement of the screw 42, the screw 42 drives the propeller 48 to rotate, and the propeller 48 is used to mix and disturb the water stored in the water tank 41, so that the impurities are evenly distributed in the water body. When the extrusion plate 43 reaches the end, the extrusion plate 43 pushes away the block 49, so that the remaining cooling water is discharged through the outlet pipe 410. By not using the remaining cooling water with a higher solubility in the final sediment, the purpose of avoiding the blockage of the hose 44 as much as possible is achieved, and the maintenance frequency of the cooling device 4 is reduced.

[0030] The anti-tipping device 5 includes an annular bottom block 51, an L-shaped frame 52 and a stud 53. The annular bottom block 51 is slidably installed on the side of the mobile platform 1, the L-shaped frame 52 is fixed on the top surface of the mobile platform 1, and the stud 53 is rotatably installed on the top surface of the L-shaped frame 52. The annular bottom block 51 is threadedly connected to the bottom end of the stud 53. When the drilling sampling point is determined, the stud 53 is screwed to increase the distance between the annular bottom block 51 and the L-shaped frame 52, so that the annular bottom block 51 moves downward, and the annular bottom block 51 is used to increase the contact area between the entire device and the ground, thereby achieving the purpose of stabilizing the coring machine, avoiding the corer from deflecting or shaking during drilling, optimizing the operation that previously required manpower to resist the corer, and making the device more labor-saving and convenient.

[0031] The anti-dumping device 5 also includes a T-shaped bottom block 54 and a slider 55, a distance-adjusting block 56, and an elastic column 57. Rectangular grooves are provided on both sides of the annular bottom block 51. The T-shaped bottom block 54 is slidably mounted on the inner wall of the rectangular groove. The slider 55 is slidably mounted on the top surface of the annular bottom block 51. The distance-adjusting block 56 is fixed on the inner side of the slider 55. The distance-adjusting block 56 is located on the movement track of the T-shaped bottom block 54. A spring is provided between the slider 55 and the top surface of the annular bottom block 51. One end of the elastic column 57 is fixed in the groove on the top surface of the annular bottom block 51, and the other end of the elastic column 57 is fixed to the top of the T-shaped bottom block 54. Due to the poor building environment, in some places where the ground is laterally inclined or partially concave, it can be directly pressed When the lower T-shaped bottom block 54 and the elastic column 57 are contracted, the T-shaped bottom block 54 squeezes the distance-adjusting blocks 56 to both sides, and the distance-adjusting blocks 56 drive the sliders 55 to slide to both sides. When the bottom of the T-shaped bottom block 54 contacts the ground at the recess, the slider 55 rebounds inward under the action of the spring force, and the slider 55 drives the distance-adjusting blocks 56 to rebound inward. The distance-adjusting blocks 56 are used to limit the upward rebound trajectory of the T-shaped bottom block 54, thereby achieving the purpose of reducing the contact point between the local bottom surface of the annular bottom block 51 and the ground, increasing the anti-dumping effect, and preventing the device from tilting sideways. When unlocking is required, the sliders 55 are pushed open to both sides, the elastic column 57 rebounds upward, and the elastic column 57 drives the T-shaped bottom block 54 to move upward and reset.

[0032] When in use, cooling water is added to the water tank 41 before drilling and sampling. When the push plate 32 is pushed, the push plate 32 drives the screw 42 to move forward, and the screw 42 drives the extrusion plate 43 to move forward. The extrusion plate 43 pushes the cooling water inside the water tank 41 to drain, so that it reaches the spray ring 45 through the hose 44, and the cooling water is sprayed out through the spray ring 45, thereby cooling the surface of the special-shaped drill tube 34, and also achieving the purpose of lubrication, avoiding the drill tube from overheating and becoming brittle after a long time of use, and also achieving a certain purpose of preventing dust. Then, the scraper strip 46 is used to scrape and clean the outer wall of the special-shaped drill tube 34 to clean and scrape away the wet wall powder. , so as to prevent it from clogging the channel and making it inconvenient to pull out the sample later; since the automatic coring machine is used in a construction site and other use environment all year round, the cooling water source used also contains a lot of impurities, which can easily cause precipitation and siltation in the water tank 41, and then cause the hose 44 to be blocked. Therefore, the filter 47 is used to isolate the impurities in the water tank 41. At the same time, during the movement of the screw 42, the screw 42 drives the propeller 48 to rotate, and the propeller 48 is used to mix and disturb the water stored in the water tank 41, so that the impurities are evenly distributed in the water body. When the extrusion plate 43 reaches the end, the extrusion plate 43 pushes away the block 49, so that the remaining cooling water is discharged through the outlet pipe 410. By not using the remaining cooling water with a higher solubility in the final sediment, the purpose of avoiding the blockage of the hose 44 as much as possible is achieved, and the maintenance frequency of the cooling device 4 is reduced.

[0033] When the sampling point of the drilling hole is determined, the stud 53 is screwed to increase the distance between the annular bottom block 51 and the L-shaped frame 52, so that the annular bottom block 51 moves downward, and the annular bottom block 51 is used to increase the contact area between the device as a whole and the ground, thereby achieving the purpose of stabilizing the coring machine, avoiding the deviation or shaking of the coring machine during drilling, optimizing the operation of the coring machine that previously required manpower to resist, and making the device more labor-saving and convenient; due to the poor building environment, in some places where the ground is laterally inclined or partially concave, the T-shaped bottom block 54 can be directly pressed, the elastic column 57 is contracted, and the T-shaped bottom block 54 is squeezed to both sides. The distance-adjusting block 56 is pressed, and the distance-adjusting block 56 drives the slider 55 to slide to both sides. When the bottom of the T-shaped bottom block 54 contacts the ground in the depression, the slider 55 rebounds inward under the action of the spring force, and the slider 55 drives the distance-adjusting block 56 to rebound inward. The distance-adjusting block 56 is used to limit the upward rebound trajectory of the T-shaped bottom block 54, so as to achieve the purpose of reducing the contact point between the local bottom surface of the annular bottom block 51 and the ground, increase the anti-dumping effect, and prevent the device from tilting sideways. When unlocking is required, the sliders 55 are pushed to both sides, the elastic column 57 rebounds upward, and the elastic column 57 drives the T-shaped bottom block 54 to move upward and reset.
