[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the embodiments and the drawings. The illustrative embodiments and descriptions thereof of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0026] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present invention. However, it is obvious to those of ordinary skill in the art that the present invention does not have to adopt these specific details. In other embodiments, well-known structures, circuits, materials or methods are not specifically described in order to avoid obscuring the present invention.

Thus, the phrases "one embodiment", "embodiment", "one example" or "example" appearing throughout the specification do not necessarily all refer to the same embodiment or example. In addition, the specific features, structures or characteristics can be combined in any appropriate combination and / or sub-combination in one or more embodiments or examples. In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] In the description of the present invention, the orientation or positional relationship indicated by terms such as "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "high", "low", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the protection scope of the present invention.

[0029] Embodiment: Regarding the sampling operation in the slope environment, the soil sampling device for geology is proposed herein to better complete the sampling operation of the slope, making the development and completion of the sampling operation smoother; at the same time, there is no need for the staff to move onto the slope, effectively avoiding the risk of the staff falling and effectively ensuring the safety of the staff.

[0030] Specifically: As Figures 1-8 shown, a soil sampling device for geology includes a sampling vehicle 1 and a fixing rod 2; One end of the sampling vehicle 1 is provided with a fixing groove adapted to the fixing rod 2. Correspondingly, the fixing rod 2 has a first working position inserted in the fixing groove and a second working position outside the fixing groove; A towing rope 3 for connecting the sampling vehicle 1 and a reel for retracting and releasing the towing rope 3 are provided on the fixing rod 2; Correspondingly, when the fixing rod 2 is in the second working position, the fixing rod 2 is inserted into the base body, and the towing rope 3 is released through the reel, so that the sampling vehicle 1 moves down the slope and samples.

[0031] Among them, the sampling vehicle 1 is used to replace manual labor and automatically complete the sampling operation, reducing the workload of the staff and lowering the labor intensity of the staff. The fixing rod 2 serves as an anchor point to facilitate the lifting and lowering of the sampling vehicle 1 along the slope and complete the sampling operation; thus, the staff can perform relevant auxiliary operations at the slope edge, and there is no need for the staff to move onto the slope in person, with better safety.

[0032] It is easy to understand that the soil sampling device for geology can also be used for slopes such as soil slopes and mountain slopes, with a wide range of applications and good practicability.

[0033] It should be noted that for non-slope terrains such as flat lands, the soil sampling device for geology can also perform sampling operations. At this time, according to specific operation requirements, the fixing rod 2 is selected to be in the first working position or the second working position.

[0034] During transportation, the fixing rod 2 is in the first working position and connected to the sampling vehicle 1 to maintain their connection, avoiding accidental situations such as loss or entanglement of the towing rope 3 and reducing the workload of the staff.

[0035] During operation, taking slope sampling as an example for illustration, the staff member moves to the top of the slope, removes the fixing rod 2 from the sampling vehicle 1, inserts the fixing rod 2 into the slope, and selects the insertion depth of the fixing rod 2 according to the actual situation to ensure the fixing effect. Then the staff member lowers the sampling vehicle 1 onto the slope, slowly releases the towing rope 3 through the winch, and the sampling vehicle 1 gradually moves downward along the slope until it reaches a certain sampling point. The sampling vehicle 1 stops and conducts the sampling operation. It should be noted that the towing rope 3 restricts the sampling vehicle 1 to move only in a straight line. If there are multiple sampling points on this straight line, repeat the above process until the sampling is completed. After the sampling is completed, take in the towing rope 3 and retrieve the sampling vehicle 1.

[0036] In addition, if the sampling vehicle 1 is dedicated to slope sampling, when the sampling vehicle 1 moves along the slope, its downward movement can be driven by gravity, and its upward movement can be pulled by the towing rope 3, then the sampling vehicle 1 may not be provided with a power unit to simplify the structure of the sampling vehicle 1. On the contrary, if the sampling vehicle 1 is also used for sampling operations in areas such as flat ground, in order to achieve automated operations, auxiliary units such as a power unit, a control unit, and an identification unit are provided on the sampling vehicle 1 to improve the intelligence level of the sampling vehicle 1.

[0037] Based on this, there are various implementation schemes for the sampling vehicle 1 to facilitate better completion of the sampling operation.

[0038] In a possible implementation manner, the fixing rod 2 includes an outer cylinder 201, a control rod 202, and a drill rod 203; The outer cylinder 201 has opposite ends, one of which is provided with a control hole adapted to the control rod 202, and the other end is open and used to connect the drill rod 203; The control rod 202 is configured as a T-shaped rod and is rotatably arranged on the outer cylinder 201 through the control hole. Correspondingly, a limiting disk that extends outward is provided at the control rod 202 near the control hole; The drill rod 203 passes through the open end of the outer cylinder 201. Correspondingly, a control hole connected to the control rod 202 is provided at the upper end of the drill rod 203, and a drill bit is provided at the lower end of the drill rod 203; Correspondingly, a sleeve sleeved on the control rod 202 is provided inside the outer cylinder 201. One end of the towing rope 3 is wound around the sleeve, and the other end passes through the outer cylinder 201 and is connected to the sampling vehicle 1; Correspondingly, when one of the drill rod 203 and the sleeve is connected to the control rod 202, the drill rod 203 or the sleeve is driven to rotate through the control rod 202 so that the drill rod 203 drills or the sleeve takes in and releases the towing rope 3. Correspondingly, the control rod 202 and the sleeve form a winch.

[0039] Based on the above design, a manually controlled fixing rod 2 is provided here. Specifically: The control rod 202 is rotatably arranged on the outer cylinder 201. Taking the rotation of the control rod 202 as the driving force, the drill rod 203 or the sleeve is driven to rotate. Among them, the rotation of the drill rod 203 is used for drilling into the base body, so that the fixing rod 2 can be better fixed on the base body; the rotation of the sleeve is used for taking in and releasing the traction rope 3, so as to control the position of the sampling vehicle 1 on the slope.

[0040] For the drill rod 203, it has two working states. One is not connected to the control rod 202. At this time, the staff can apply pressure to break the base body with the drill bit of the drill rod 203, so that the fixing rod 2 enters the base body. The other is connected to the control rod 202. The rotation of the drill rod 203 is driven by the rotation of the control rod 202 to realize drilling, so that the fixing rod 2 enters the base body. In actual work, the staff can choose according to the actual situation to ensure that the fixing rod 2 is effectively fixed.

[0041] Optionally, a detachable additional rod 204 is provided on the control rod 202. The additional rod 204 includes a first rod body and a second rod body that are detachably connected; A first hole body is provided on the drill rod 203. Correspondingly, second hole bodies that are coaxial and communicate with the first hole body are provided on both the outer cylinder 201 and the control rod 202. Correspondingly, the first hole body and the second hole body form a first control hole 205; A third hole body is provided on the sleeve. Correspondingly, fourth hole bodies that are coaxial and communicate with the third hole body are provided on both the outer cylinder 201 and the control rod 202. Correspondingly, the third hole body and the fourth hole body form a second control hole 206; When one of the first rod body and the second rod body is inserted into the first control hole 205, the control rod 202 is connected to the drill rod 203; Correspondingly, when one of the first rod body and the second rod body is inserted into the second control hole 206, the control rod 202 is connected to the sleeve.

[0042] Based on the above design, taking the staff holding the first rod body as an example, when connecting the drill rod 203, the staff removes the additional rod 204 and holds the first rod body, moves the additional rod 204 until the second rod body is inserted into the first control hole 205, and then the staff disassembles the first rod body and the second rod body. At this time, the control rod 202 and the drill rod 203 are connected through the second rod body, so that the control rod 202 drives the drill rod 203 to rotate. On the contrary, the first rod body extends into the first control hole 205 and connects the second rod body, and then the second rod body is taken out to release the connection between the control rod 202 and the drill rod 203.

[0043] It should be noted that when connecting the control rod 202 and the drill rod 203 through the second rod body, the length of the second rod body should be controlled to avoid the end of the second rod body extending onto the outer cylinder 201 and hindering rotation.

[0044] Similarly, the connection between the control rod 202 and the sleeve can also be achieved through the additional rod 204, which will not be elaborated here.

[0045] It is easy to understand that the control rod 202 is provided with a slot structure for accommodating the additional rod 204, and the first rod body and the second rod body can be connected by any suitable detachable connection method.

[0046] In addition, the fixed rod 2 can also be configured as a rod body structure and a retractor provided on the rod body structure. Any suitable existing model can be selected for the retractor to simplify the structure of the fixed rod 2 and reduce the economic cost.

[0047] In a possible implementation, the sampling vehicle 1 includes a vehicle body 101, a sampling tube 102, a placement rack 103, and a drive module 104; An installation cavity 105 is provided inside the vehicle body 101. Correspondingly, the sampling tube 102, the placement rack 103, and the drive module 104 are all located in the installation cavity 105; a sampling hole 106 is provided on the bottom surface of the vehicle body 101, and the drive module 104 is covered on the sampling hole 106; A plurality of sampling tubes 102 are provided and respectively penetrate through the placement rack 103. The placement rack 103 is rotatably arranged inside the vehicle body 101. Correspondingly, the placement rack 103 rotates so that one of the sampling tubes 102 faces the drive module 104; The drive module 104 is fixed inside the vehicle body 101 and is used to drive the sampling tube 102 to rotate reciprocally to drill for samples and withdraw from the drilling area; Correspondingly, a detachable cover plate 107 is provided on the top surface of the vehicle body 101. When the cover plate 107 is removed, the installation cavity 105 communicates with the outside to disassemble and assemble the sampling tube 102 on the placement rack 103.

[0048] Based on the above design, any suitable existing model can be selected for the vehicle body 101. A plurality of sampling tubes 102 are provided. Correspondingly, a plurality of placement holes adapted to the sampling tubes 102 are provided on the placement rack 103, that is, one sampling tube 102 is provided on each placement hole. Thus, the sampling vehicle 1 can carry a plurality of sampling tubes 102, thereby completing multiple sampling operations and reducing the reciprocating lifting and lowering of the sampling vehicle 1 caused by replacing the sampling tube 102. The placement rack 103 has a rotating function. After one of the sampling tubes 102 completes the sampling operation, the position of the sampling tube 102 is moved by the rotation of the placement rack 103, so that the sampled sampling tube 102 is away from the drive module 104 and the sampling hole 106, and one of the unsampled sampling tubes 102 faces the drive module 104 and the sampling hole 106.

[0049] Meanwhile, a cover plate 107 is provided on the vehicle body 101. When the staff disassembles and installs the sampling tube 102, the cover plate 107 is removed to connect the installation cavity 105 to the outside. The staff takes out the sampled sampling tube 102 and places the unsampled sampling tube 102 on the idle placement hole on the placement rack 103.

[0050] In addition, the driving module 104 is used to drive the sampling tube 102 to reciprocate, so that the sampling tube 102 is inserted into the substrate to collect samples, and then reset and separated from the substrate, thus completing the sampling operation.

[0051] Optionally, the placement rack 103 includes a first driver 108, a rotating shaft 109, and placement cantilevers 110; The first driver 108 is arranged inside the vehicle body 101, and the output end of the first driver 108 is connected to and drives the rotating shaft 109 to rotate; the rotating shaft 109 is rotatably arranged inside the vehicle body 101, and the rotating shaft 109 is connected to a plurality of placement cantilevers 110 through a plurality of differential sleeves 4 respectively; there are a plurality of placement cantilevers 110 and they are evenly distributed in the circumferential direction of the rotating shaft 109. Correspondingly, the sampling tube 102 is threaded through the placement cantilevers 110. The differential sleeve 4 has a rotating station, a lifting station, and an idle station. Correspondingly, when the differential sleeve 4 is at the rotating station, the rotating shaft 109 drives the corresponding placement cantilever 110 to rotate along the circumferential direction of the rotating shaft 109, so that one of the placement cantilevers 110 and the corresponding sampling tube 102 face the driving module 104; when the differential sleeve 4 is at the lifting station, the rotating shaft 109 drives the corresponding placement cantilever 110 to lift and lower, so that the sampling tube 102 on the placement cantilever 110 is connected to the driving module 104; correspondingly, when one of the differential sleeves 4 is at the lifting station, the remaining differential sleeves 4 are at the idle station, so that the remaining placement cantilevers 110 remain relatively stationary.

[0052] Based on the above design scheme, for the sampling tube 102, its movement can be divided into two types. Movement one is to face or separate from the driving module 104 through displacement, so that one of the multiple sampling tubes 102 is ready for sampling operation, and the remaining sampling tubes 102 are in the idle state; Movement two is that for the sampling tube 102 ready for sampling, it needs to lift a certain height to ensure that the driving force of the driving module 104 acts effectively on the sampling tube 102, so as to drive the sampling tube 102 to complete the sampling operation.

[0053] In view of this, in the placement rack 103, the rotating shaft 109 is connected to a plurality of placement cantilevers 110 through the differential sleeve 4, which also connects the sampling tubes 102 located on the corresponding placement cantilevers 110. And the differential sleeve 4 has three stations, namely the rotating station, the lifting station, and the idle station, so that the sampling tube 102 can complete the corresponding movement.

[0054] Specifically: When the differential sleeve 4 is in the rotation station, the rotating shaft 109 drives the corresponding placement cantilever 110 to rotate circumferentially along the rotating shaft 109. At this time, it should be ensured that all the sampling tubes 102 rotate synchronously until one of the placement cantilevers 110 and the corresponding sampling tube 102 face the driving module 104. When the differential sleeve 4 is in the lifting station, the rotating shaft 109 drives the corresponding placement cantilever 110 to lift and lower, so that the sampling tube 102 on the placement cantilever 110 is connected to the driving module 104; at this time, the remaining differential sleeves 4 should be in the idle station to prevent the remaining sampling tubes 102 from lifting and lowering.

[0055] Optionally, a housing 5 is sleeved on the rotating shaft 109, and a plurality of differential sleeves 4 are arranged at intervals in the housing 5. Correspondingly, the anti-cantilever passes through the housing 5 and is connected to the corresponding differential sleeve 4; The differential sleeve 4 includes a first base 401, a limiting rod 402 and an arc-shaped transmission block 403. The first base 401 is respectively connected to the limiting rod 402 and the arc-shaped transmission block 403, and drives the two to expand and contract respectively to control whether the two are connected to the rotating shaft 109; Correspondingly, when the limiting rod 402 extends out and is connected to the rotating shaft 109, the differential sleeve 4 is in the rotation station; when the arc-shaped transmission block 403 extends out and is connected to the rotating shaft 109, the differential sleeve 4 is in the lifting station; when both the limiting block and the arc-shaped transmission block 403 are separated from the rotating shaft 109, the differential sleeve 4 is in the idle station; Correspondingly, the limiting rod 402 is arranged on the arc-shaped transmission block 403. One of the inner side surface of the arc-shaped transmission block 403 and the outer peripheral surface of the rotating shaft 109 is provided with an inward concave arc-shaped driving groove, and the other is provided with an outward convex arc-shaped driving strip.

[0056] Here, the structure of the differential sleeve 4 is described in combination to illustrate the change of its working station: The power is output through the first base 401 to make the limiting rod 402 and the arc-shaped transmission block 403 expand and contract. Specifically: When the limiting rod 402 extends out and is inserted into the rotating shaft 109, and the arc-shaped transmission block 403 remains separated from the rotating shaft 109, the rotating shaft 109 synchronously drives the differential sleeve 4, the placement cantilever 110 and the sampling tube 102 to rotate, and the differential sleeve 4 is in the rotation station.

[0057] When the arc-shaped transmission block 403 extends out and is inserted into the rotating shaft 109, and the limiting rod 402 remains separated from the rotating shaft 109, the rotation of the rotating shaft 109 is converted into the lifting of the differential sleeve 4 through the arc-shaped driving groove and the arc-shaped driving strip, so that the placement cantilever 110 and the sampling tube 102 also lift and lower, and the differential sleeve 4 is in the lifting station.

[0058] When both the limiting block and the arc-shaped transmission block 403 are separated from the rotating shaft 109, the rotation of the rotating shaft 109 will not be transmitted to the placement cantilever 110, and the corresponding differential sleeve 4, placement cantilever 110 and sampling tube 102 remain relatively stationary, and the differential sleeve 4 is in the idle station.

[0059] It is worth noting that, in order to coordinate the lifting of the differential sleeve 4, the housing 5 is provided with corresponding openings and springs to guide the lifting direction of the differential sleeve 4. At the same time, the rotating shaft 109 can rotate forward and reverse, and the forward and reverse rotation of the rotating shaft 109 is used to drive the differential sleeve 4 to lift.

[0060] Preferably, the limiting rod 402 is passed through the arc-shaped transmission block 403 to reduce space occupation.

[0061] In a possible implementation, the driving module 104 includes a second base 111 , a driving ring 112 , a second driver 113 , and a cleaning member 114 ; The second base 111 is provided with a transmission hole 115 which is coaxial with and connected to the sampling hole 106, and the driving ring 112 is rotatably disposed on the second base 111 and is coaxial with the transmission hole 115; The second driver 113 is located outside the second base 111 and is used to drive the driving ring 112 to rotate. The cleaning member 114 is disposed on the second base 111 and below the driving ring 112 . Accordingly, the cleaning member 114 is used to clean the outer wall of the sampling tube 102 .

[0062] Based on the above design, the second driver 113 is connected to the driving ring 112 through any suitable transmission structure, so as to transmit power to the driving ring 112 to rotate the driving ring 112. Accordingly, a driving structure similar to an arc-shaped driving groove and an arc-shaped driving strip is provided between the driving ring 112 and the sampling tube 102. When the sampling tube 102 moves toward the driving ring 112 under the action of the rotating shaft 109, the driving structures between the driving ring 112 and the sampling tube 102 are combined with each other, so that the driving ring 112 drives the sampling tube 102 to rotate and move toward the substrate, and the sampling tube 102 drills into the substrate and obtains the sample.

[0063] Similarly, the second driver 113 also has forward and reverse functions, so that the drive ring 112 can reverse and drive the sampling tube 102 to separate from the base, so as to realize the recovery of the sampling tube 102. After the sampling tube 102 is reset and separated from the drive ring 112, the sampling tube 102 is also plugged into the placement hole of the placement cantilever 110, and the placement frame 103 rotates and realizes the replacement of the sampling tube 102, so that the next empty sampling tube 102 faces the driving module 104.

[0064] It is worth noting that for some substrates, such as areas with soft soil, it is relatively easy to insert the sampling tube 102 into the substrate, but when the sampling tube 102 is recovered, there will be attachments on the outer wall of the sampling tube 102. At this time, the cleaning member 114 is used to clean the outer wall of the sampling tube 102, thereby improving the cleanliness of the sampling tube 102 and the vehicle body 101.

[0065] Optionally, the cleaning member 114 is selected from a cleaning plate 116 or a cleaning brush 117. Based on this, for areas with relatively soft geology such as silt, there are more attachments and strong adhesion. The cleaning member 114 preferably selects the cleaning plate 116 to scrape off the attachments through the cleaning plate 116. On the contrary, for areas with relatively hard geology such as rock and soil, there are fewer attachments and mainly particulate matter. The cleaning member 114 preferably selects the cleaning brush 117 to save costs.

[0066] In a possible implementation, a placement hole adapted to the sampling tube 102 is provided on the placement cantilever 110 of the placement rack 103, and a driving hole adapted to the sampling tube 102 is provided on the driving ring 112 of the driving module 104. A reduced-diameter ring 6 is detachably provided on both the placement hole and the driving hole. Correspondingly, the cleaning member 114 of the driving module 104 includes a telescopic seat 118 for driving the cleaning plate 116 or the cleaning brush 117 to expand and contract.

[0067] Based on the above design, for different sampling operation requirements, sampling tubes 102 of different diameters may be used. At this time, the reduced-diameter ring 6 can be used to change the diameters of the placement hole and the driving hole to improve the adaptability to the sampling tube 102.

[0068] Correspondingly, the reduced-diameter ring 6 has an outer ring 601 and an inner ring 602 that are opposite to each other. The outer ring 601 is used to connect the placement cantilever 110 or the driving ring 112. The structure of the inner ring 602 is the same as that of the placement hole or the driving hole to ensure the corresponding functions are achieved. In addition, there is a connecting structure 603 with any suitable structure between the outer ring 601 and the inner ring 602 to ensure that the outer ring 601 and the inner ring 602 are effectively connected as a whole.

[0069] It is easy to understand that the reduced-diameter ring 6 is provided in multiple specifications to adapt to sampling tubes 102 of different diameters. Correspondingly, the staff can select the reduced-diameter ring 6 with a suitable specification according to the specific operation requirements.

[0070] It should be noted that to ensure the cleaning effect of the cleaning member 114, the driving module 104 drives the cleaning member 114 to move through the telescopic seat 118 so that the position of the cleaning member 114 is adapted to the inner diameter of the corresponding reduced-diameter ring 6 to ensure that the cleaning effect meets the standard.

[0071] Optionally, through holes are provided on the cleaning plate 116, and retractable cleaning brushes 117 are provided in the through holes. An additional cleaning block 119 that protrudes outward and is located below the through holes is provided on the cleaning surface of the cleaning plate 116. Based on this, the cleaning brush 117 is built into the cleaning plate 116. When the cleaning plate 116 is selected, the cleaning brush 117 can be kept retracted. On the contrary, when the cleaning brush 117 is selected, the cleaning brush 117 can be moved out of the cleaning plate 116. The staff does not need to disassemble and install additionally, which is more convenient to use.

[0072] It should be noted that, in order to prevent impurities such as silt from invading the through holes and to improve the cleaning effect, additional cleaning blocks 119 are provided on the cleaning plate 116. When the cleaning plate 116 is cleaning, the silt is scraped off by the additional cleaning blocks 119, reducing the contact area between the silt and the cleaning plate 116. Subsequently, the additional cleaning blocks 119 can be replaced, reducing the workload of sanitation cleaning. It is easy to understand that the additional cleaning blocks 119 are preferably made of flexible materials to reduce the wear on the outer wall surface of the sampling tube 102.

[0073] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only the specific embodiments of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
