[0042] Compared with the prior art, the beneficial effects of the present invention are as follows:

Meanwhile, the motor on the support arm can adjust the rotation angle of the leveling scraper, and with the toothed bottom structure, it can adapt to the leveling needs of different terrains and soil conditions. The motor's self-locking function ensures operational stability.

[0044] The sampling assembly lifts and lowers the base via a lifting guide rail. Combined with the distribution design of multiple sampling units on the drill rod, it can perform layered sampling of soil at different depths and heights during drilling, meeting the refined requirements for data collection of different strata in geological exploration.

[0045] The impact module uses gas drive and the elastic cooperation of spring one to enable the piston plate to drive the drilling unit to reciprocate and impact. Combined with the protrusion one at the bottom of the drill bit, it significantly improves the drilling penetration of hard soil and avoids sampling obstruction.

[0046] The auxiliary drilling module drives the flow of medium in the second compression chamber through the reciprocating motion of the connecting block, thereby controlling the reciprocating extension and retraction of the reaming tooth plate to improve the drilling and reaming effect. At the same time, it drives the piston plate in the third compression chamber to intermittently impact the second protrusion, further enhancing the drilling capability in hard soil and ensuring smooth sampling.

[0047] The elastic support module provides elastic cushioning for the drill bit through the cooperation of spring 2 and push rod, reducing the impact damage to the drill bit caused by soil clods during drilling and extending the service life of the equipment.

[0048] The sampling unit utilizes the reciprocating flow of gas in the first guide channel to drive the sealing plate to open and close automatically through the connecting hole: during drilling, the sealing plate is closed to prevent soil from entering the sampling chamber in advance; during the sampling stage, the sealing plate opens, and in conjunction with the rotation of the drill rod, loose soil quickly enters the sampling chamber, completing the sampling without manual intervention; multiple sampling units work independently, and soil samples from different locations can be collected simultaneously, improving sampling efficiency and data comprehensiveness; the setting of the elastic traction rope ensures that the opening and closing action of the sealing plate is stable and reliable, avoiding jamming.

[0068] A leveling assembly is disposed at the bottom of the lifting plate 2;

Compared with the prior art, the present invention, through the coordinated setting of the sampling assembly and the leveling assembly, avoids the problem that most existing geological exploration equipment cannot simultaneously achieve leveling and sampling functions, requiring the replacement of multiple devices to achieve leveling and sampling functions, which has certain limitations.

[0072] In one embodiment of the present invention, please refer to Figures 1-11 The support assembly includes a mounting base 1, which is slidably connected to the lifting plate 2. The end of the mounting base 1 away from the lifting plate 2 has a docking seat for connecting a working vehicle.

[0073] In this embodiment, the telescopic cylinder 3 can adjust the working height of the leveling assembly by driving the lifting plate 2 to move up and down, which facilitates the layered leveling operation.

[0074] In one embodiment of the present invention, please refer to Figures 1-11 The impact module includes:

[0075] A compression chamber 11 is provided inside the drill pipe 6, and a piston plate 12 is slidably installed inside the compression chamber 11.

[0076] A spring 10 is used to elastically pull the piston plate 12. One end of the spring 10 is fixedly connected to the top of the compression chamber 11, and the other end of the spring 10 is fixedly connected to the piston plate 12.

[0078] And a connecting assembly for connecting the piston plate 12 and the connecting block 14;

[0079] The piston plate 12 has a rectangular structure, and the side of the piston plate 12 fits against the inner wall of the compression chamber 11; this facilitates the connection block 14 to rotate with the drill rod 6.

[0080] The connection component includes:

[0081] A linkage rod 13 is slidably installed at the bottom of the drill rod 6, and the linkage rod 13 is fixedly connected to the piston plate 12.

[0082] A connecting sleeve 7 is fixedly installed at the bottom of the linkage rod 13, and the connecting sleeve 7 is connected to the connecting block 14; wherein the connecting sleeve 7 and the connecting block 14 are detachably connected, and the specific connection method is not specifically limited here.

[0083] In this embodiment, the base 5 is also provided with a bracket 34, and the bracket 34 is provided with a conduit 33 connected to the flow channel 9. The conduit 33 is rotatably connected to the drill rod 6. The conduit 33 is connected to an external air source. By using the flow channel 9 to fill and draw air into the compression chamber 11, and with the elastic traction of the spring 10, the piston plate 12 can reciprocate within the compression chamber 11. Through the cooperation of the linkage rod 13 and the connecting sleeve 7, the connecting block 14 and the drill rod 6 can be driven to generate relative movement, so that the drilling unit has a certain impact effect, thereby improving the drilling effect and avoiding obstruction of the sampling process.

[0084] In one embodiment of the present invention, please refer to Figures 1-11 The drill bit 8 is also provided with multiple sets of protrusions 17 at the end away from the connecting block 14;

[0085] The elastic support module includes:

[0086] A push rod 20 is fixedly installed at the bottom of the connecting block 14, and the drill bit 8 has a through hole that is slidably connected to the push rod 20.

[0087] A second spring 19 is used to elastically press the drill bit 8. One end of the second spring 19 is fixedly connected to the connecting block 14, and the other end of the second spring 19 is fixedly connected to the drill bit 8.

[0088] And a protective enclosure 15, which is fixedly installed on the drill bit 8 and is slidably connected to the connecting block 14;

[0089] The push rod 20 is a rod with a rectangular cross-section.

[0090] The auxiliary drilling module includes:

[0091] The reaming tooth plate 16 is rotatably connected to the drill bit 8 via a support shaft 22, and multiple sets of the reaming tooth plate 16 are provided on the side wall of the drill bit 8.

[0092] Telescopic cylinder 25, one end of which is rotatably connected to the reaming tooth plate 16, and the other end of which is rotatably connected to the drill bit 8 via a support shaft 23; wherein the telescopic cylinder 25 can be pneumatically driven or hydraulically driven, and is not specifically limited here;

[0093] A compression chamber 26 is provided inside the drill bit 8, and a piston plate 21 fixedly connected to the push rod 20 is slidably installed in the compression chamber 26; wherein the compression chamber 26 is pre-filled with gas or oil.

[0094] And conduit 24, which is used for communication between telescopic cylinder 25 and compression chamber 26;

[0095] The auxiliary drilling module also includes:

[0096] A compression chamber 30 is provided inside the drill bit 8, and the compression chamber 30 is connected to the compression chamber 26 through a guide channel 27.

[0097] Piston plate 3 28 is slidably installed in compression chamber 3 30, and the bottom of piston plate 3 28 is provided with multiple sets of protrusions 2 18. The bottom of drill bit 8 is provided with a round hole for protrusions 2 18 to pass through.

[0098] And a spring 29 for elastically supporting the piston plate 3 28, the spring 29 being disposed within the compression chamber 3 30.

[0099] In this embodiment, the drill bit 8 can perform drilling work by rotating with the drill rod 6. The arrangement of multiple sets of protrusions 17 improves the drilling effect on hard soil. When the connecting block 14 reciprocates relative to the drill rod 6, the connecting block 14 uses the push rod 20 to drive the piston plate 21 to reciprocate within the compression chamber 26. This allows the medium (oil or gas) within the compression chamber 26 to enter and exit the telescopic cylinder 25 through the conduit 24. The telescopic cylinder 25 drives the reaming tooth plate 16 to reciprocate around the support shaft 22, causing the reaming tooth plate 16 to follow the drill rod 6. During the rotation of the drill bit 8, the outward expansion distance of the reaming tooth plate 16 can continuously change, improving the reaming effect and thus the drilling effect. The medium in the second compression chamber 26 will also enter and exit the third compression chamber 30 through the second guide channel 27, and in conjunction with the third spring 29, the piston plate 28 will reciprocate within the third compression chamber 30, causing the second protrusion 18 to intermittently protrude from the bottom of the drill bit 8. Combined with the impact, this further improves the drilling effect on hard soil, making it easier to sample in hard soil areas. During the drilling process, the soil on the sidewall of the borehole will loosen, facilitating sampling.

[0100] In one embodiment of the present invention, please refer to Figures 1-11 The leveling assembly includes:

[0101] Support arm 31, the support arm 31 is fixedly installed on both sides of the bottom of the lifting plate 2;

[0102] A flat scraper 32 is rotatably installed between two sets of support arms 31. The support arms 31 have a motor for driving the flat scraper 32 to rotate, and the bottom of the flat scraper 32 has a toothed structure. The motor is designed with a brake assembly, which can achieve self-locking in the stopped state, so as to fix the flat scraper 32 at a preset angle.

[0103] In this embodiment, by rotating the leveling scraper 32, the working angle of the leveling scraper 32 can be adjusted to meet the usage requirements of different sites. The work vehicle can perform leveling operations by driving the leveling assembly to move horizontally through the support assembly.

[0104] In one embodiment of the present invention, please refer to Figures 1-11 The sampling unit includes:

[0105] A sampling chamber 35 for containing soil is provided inside the drill rod, and the surface of the drill rod has an opening that communicates with the sampling chamber 35.

[0106] The sealing plate 36 is used to seal the opening. A cavity for sliding installation of the sealing plate 36 is provided in the drill rod. A piston block that fits against the inner wall of the cavity is provided at the end of the sealing plate 36. Two sets of sealing plates 36 are symmetrically arranged.

[0107] Elastic traction rope 38 is used to connect the piston blocks on two sets of drill rods, and multiple sets of elastic traction rope 38 are provided. The middle part of the elastic traction rope 38 is fixed in the cavity.

[0108] And a connecting hole 37, which is used for communication between the cavity and the flow channel 9.

[0109] In this embodiment, during the drilling process of the drilling unit, when the flow channel 9 reciprocates to inflate and draw air into the compression chamber 11, the gas in the flow channel 9 will also enter and exit the cavity of the drill rod through the connecting hole 37, thereby pushing the piston block to move. The piston block will push the sealing plates 36 to move closer together to complete the sealing. When the gas in the cavity is extracted, the elastic traction rope 38 will use the piston block to pull the two sets of sealing plates 36 apart. At the same time, the drill rod continues to rotate, so that the loose soil on the borehole wall can enter the sampling chamber 35 to complete the sampling. The coordinated setting of multiple sampling units can perform sampling at different heights.

[0110] In summary, the working principle of this invention is as follows:

[0111] In use, the entire device can be mounted on a work vehicle using the support assembly. The leveling assembly can be used to level the survey site. The lifting guide rail can drive the base 5 to move up and down. When sampling is needed, the sampling assembly can be driven to move down. The drive module 4 can drive the drill rod 6 to rotate, and together with the impact module, connecting block 14, and elastic support module, it can drive the drill bit 8 to rotate for drilling. The auxiliary drilling module can further improve the drilling effect. The sampling unit can be used to take samples from the drilled hole. The specific working steps of the sampling assembly and the leveling assembly are as follows:

[0112] By rotating the leveling scraper 32, the working angle of the leveling scraper 32 can be adjusted to meet the needs of different sites. The work vehicle can perform leveling operations by driving the leveling assembly to move horizontally through the support assembly.

[0113] By connecting the conduit 33 to an external air source, and by using the flow channel 9 to inflate and draw air into the compression chamber 11, and with the elastic traction of the spring 10, the piston plate 12 can reciprocate within the compression chamber 11. Through the cooperation of the linkage rod 13 and the connecting sleeve 7, the connecting block 14 and the drill rod 6 can be driven to generate relative movement, giving the drilling unit a certain impact effect, thereby improving the drilling effect.

[0114] The drill bit 8 performs drilling operations by rotating with the drill rod 6. The multiple sets of protrusions 17 improve drilling efficiency in hard soil. When the connecting block 14 reciprocates relative to the drill rod 6, the connecting block 14 uses the push rod 20 to drive the piston plate 21 to reciprocate within the compression chamber 26. This allows the medium (oil or gas) within the compression chamber 26 to enter and exit the telescopic cylinder 25 via the conduit 24. The telescopic cylinder 25 drives the reaming tooth plate 16 to rotate reciprocally around the support shaft 22, causing the reaming tooth plate 16 to rotate with the drill bit 8. During the process, the outward expansion distance of the reaming tooth plate 16 can continuously change, improving the reaming effect and thus improving the drilling effect. In addition, the medium in the compression chamber 26 will also enter and exit the compression chamber 30 through the guide channel 27, and in conjunction with the spring 39, the piston plate 38 will reciprocate in the compression chamber 30, causing the protrusion 2 18 to intermittently protrude from the bottom of the drill bit 8. Combined with the impact, this further improves the drilling effect on hard soil, making it easier to sample in hard soil areas. During the drilling process, the soil on the sidewall of the borehole will be loosened, making it easier to sample.

[0115] During the drilling process of the drilling unit, when the flow channel 9 reciprocates to fill and draw air into the compression chamber 11, the gas in the flow channel 9 will also enter and exit the cavity of the drill rod through the connecting hole 37, thereby pushing the piston block to move. The piston block will push the sealing plates 36 to move closer together to complete the sealing. When the gas in the cavity is extracted, the elastic traction rope 38 will use the piston block to pull the two sets of sealing plates 36 apart. At the same time, the drill rod continues to rotate, so that the loose soil on the borehole wall can enter the sampling chamber 35 to complete the sampling. The coordinated setting of multiple sampling units can carry out sampling at different heights.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
