The piston seat of the present invention will be displaced due to the traction of the air pressure difference and the adsorption force, so that the piston seat can move upward inside the suction chamber to squeeze the rock and soil samples collected inside the collection inner box toward the direction of the docking plate, so that the soft rock and soil layer can be squeezed into a soil cake, and the electric push rod drives the third electric motor to move upward to separate the docking plate from the collection inner box, so that the staff can conveniently take out the soil cake and conduct subsequent soil layer sample detection. Through the above operation, the equipment can rely on the suction force to achieve convenient soil layer sample collection and sample aggregation compression, which can avoid the loosening of the collected samples, which is not conducive to detection. At the same time, compressing the rock and soil into a soil cake can also effectively avoid the rock and soil remaining inside the collection inner box.

Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, in particular to a rock and soil detection device for geological exploration. Background Art

[0002] In geological survey, the collection and testing of rock and soil samples is an important basis for analyzing geological structures and evaluating engineering geological conditions. Traditional rock and soil testing devices mostly use mechanical drilling or manual collection methods, which have the following limitations: Loose samples and poor integrity: When conventional equipment collects soft rock and soil layers, it is easy for the samples to become loose due to external disturbances, making it difficult to maintain the original structure, affecting the accuracy of subsequent physical and mechanical property tests; Depth layer confusion: When collecting soil samples at different depths, traditional methods lack an effective layer isolation mechanism, and samples at different depths are easily mixed, resulting in distorted test results; Insufficient terrain adaptability: Existing equipment mostly relies on horizontal ground operations. It is difficult to adjust the drilling angle in inclined or complex terrain, resulting in drill rod deviation and affecting sampling accuracy; Residue and cleaning difficulties: The rock and soil after collection are easy to remain inside the equipment, especially the clay soil layer, which is not only cumbersome to clean, but may also cause cross-contamination of samples. In addition, in the existing technology, although some equipment attempts to compress samples through air pressure or hydraulic pressure, the compression force control is not precise, making it difficult to form a uniform and dense soil cake, and the compression mechanism is separated from the collection unit, which increases the complexity of the operation.

[0015] The present invention provides a rock and soil detection device for geological survey, which has the following beneficial effects: 1. The staff of the present invention screws the positioning drill bit into the soil layer, so that the bottom panel can be stably fixed to the ground, which can ensure the stability of the equipment during the collection process. When the equipment collects rock and soil on a non-planar terrain, the first motor works to make the first driving gear mesh with the meshing teeth at the outer end of the steering seat and rotate, so that the steering seat can be rotated through the steering shaft. Through this design, the direction of the workbench can be changed. When the equipment is on an inclined ground, the direction of the workbench can be adjusted to keep the drilling rod in a vertical downward position during the drilling process, which can improve the drilling stability of the equipment. At the same time, this also enables the equipment to adapt to various non-horizontal drilling operations. In addition, thanks to the meshing of the first driving gear and the meshing teeth, the workbench can maintain a stable rotation angle after stopping rotation, which can avoid changes in the tilt angle during the drilling process.

[0016] 2. After the collection seat of the present invention is sleeved with the drilling rod, the electric-controlled roller can be inserted into the slide groove of the drilling rod. At this time, the electric-controlled roller rolls to drive the collection seat to move along the drilling rod, which enables the collection seat to be flexibly moved to soil layers of different depths. After the collection seat moves to the soil layer of the specified depth, it will control the internal electromagnet to be energized, and the electromagnetic force of the electromagnet can be transmitted to the magnetic pile of the drilling rod. After the magnetic pile generates magnetic force, it can attract the first armature to adsorb and squeeze the first return spring. The first armature is fixed to the sealing block, which enables the sealing block to move up synchronously. The sealing block can move up and move away from the inside of the suction groove, which enables the suction groove to be opened and connected to the feed port. In addition, the magnetic force of the electromagnet can attract the second armature, which enables the second armature to squeeze the second return spring to move up. During the upward movement of the second armature, it can drive the push block to move up synchronously and squeeze the displacement block, which enables the displacement block to squeeze the third return spring The spring drives the collection scraper to move outward, which enables the collection scraper to extend and contact the rock and soil layer. The suction pump works, which can transmit the suction force to the inside of the ventilation pipe through the through grooves of the collection inner box, and the ventilation pipe can be connected with the gripping seat by stretching the hose and rotating the butt pipe, and the gripping seat can be connected with the ventilation grooves inside the drilling rod. Through this operation, the suction force can be transmitted to the feed port through the ventilation grooves and the suction grooves. At this time, the gripping seat drives the drilling rod to rotate again, and the drilling rod drives the collection seat to rotate, which enables the collection scraper to scrape the surface of the rock and soil layer to collect the rock and soil layer at that depth. Because the feed port is located at the bottom end of the collection scraper, the scraped rock and soil layer can be sucked in from the feed port. Through the above operations, the equipment can flexibly and conveniently collect rock and soil samples of different depths. At the same time, thanks to this design, when the collected rock and soil samples are confused, the equipment can quickly and conveniently perform secondary collection of rock and soil samples of the confused depth again.

[0017] 3. The rock and soil samples collected by the present invention will enter the interior of the collection inner box due to the suction force. The use of the filter cloth layer can prevent the rock and soil from entering the interior of the suction pump. After the rock and soil samples are collected, the third motor can drive the docking plate to rotate, and the docking plate is engaged with the card slot of the collection inner box through the docking pile, so that the collection inner box can rotate synchronously with the docking plate. After the collection inner box rotates, the through slot can be covered by the collection outer box. At this time, the suction pump continues to work and the electric control valve is opened. The suction force can be transmitted to the interior of the suction chamber through the second suction pipe. After the air inside the suction chamber is sucked out, the piston seat will be displaced due to the pressure difference and the adsorption force, which allows the piston seat to move inside the suction chamber. The piston seat moves upward, and after moving upward, it can squeeze the rock and soil samples collected inside the collection inner box towards the docking plate, so that the soft rock and soil layer can be squeezed into a soil cake. After the sample is squeezed into a soil cake, the electric push rod drives the third electric motor to move upward, so that the docking plate can be separated from the collection inner box, which makes it easy for the staff to take out the soil cake, thereby facilitating the subsequent detection of soil layer samples. Through the above operations, the equipment can rely on suction force to achieve convenient soil layer sample collection and sample aggregation compression, which can avoid the loosening of the collected samples and is not conducive to detection. At the same time, compressing the rock and soil into soil cakes can also effectively avoid the rock and soil remaining inside the collection inner box, resulting in confusion of rock and soil samples.

The hydraulic cylinder 202 is arranged at the top and bottom ends of the support frame 201, and the lower pressure plate 203 is arranged at the output end of the hydraulic cylinder 202. The outer end of the lower pressure plate 203 is connected to the bearing connection seat 204, and the gripping seat 205 is arranged on the inner side of the bearing connection seat 204.

The specific operation is as follows: after the staff moves the equipment to the top of the rock and soil layer to be collected, the bottom panel 101 can be in contact with the ground. At this time, the staff screws the positioning drill bit 109 into the soil layer, so that the bottom panel 101 can be stably fixed to the ground, which can ensure the stability of the equipment during the collection process. When the equipment is used for rock and soil collection on a non-planar terrain, the equipment is first placed on an inclined surface with the steering shaft 103 rotatable to one side, and the first motor 106 works to make the first driving gear 107 mesh with the meshing tooth 105 at the outer end of the steering seat 104 and rotate, so that the steering seat 104 can be rotated through the steering shaft 103. Through this design, the workbench 1 08 is changed. When the equipment is on an inclined ground, by adjusting the direction of the workbench 108, the drilling rod 401 can always be kept in a vertical downward position during the drilling process, which can improve the drilling stability of the equipment and enable the equipment to adapt to various non-horizontal drilling operations. In addition, thanks to the engagement of the first driving gear 107 and the meshing teeth 105, the workbench 108 can maintain a stable rotation angle after stopping rotation, which can avoid changes in the tilt angle during the drilling process.

After the collection seat 601 is sleeved with the drilling rod 401, the electric-controlled roller 610 can be inserted into the slide groove 402 of the drilling rod 401. The collection seat 601 can be equipped with a lithium battery and a stepper motor according to the actual size (its wall width is generally set at 10-40 cm), wherein the stepper motor and the electromagnet 602 are powered by the lithium battery, and the stepper motor can drive the electric-controlled roller 610 to roll, and the electric-controlled roller 610 rolls, driving the collection seat 601 to move along the drilling rod 401, so that the collection seat 601 can be flexibly moved to soil layers of different depths. In the process, after the collecting seat 601 moves to the soil layer at a specified depth, the internal electromagnet 602 will be controlled to be energized, and the electromagnetic force of the electromagnet 602 can be transmitted to the magnetic pile 406 of the drilling rod 401. After the magnetic pile 406 generates magnetic force, it can attract the first armature 407 to adsorb and squeeze the first return spring 408. The first armature 407 is fixed to the sealing block 409, which enables the sealing block 409 to move up synchronously. The sealing block 409 moves up and moves away from the inside of the suction groove 410, which enables the suction groove 410 to be opened and connected to the feed port 609. In addition, the magnetic force of the electromagnet 602 can attract the second armature 603, which enables the second armature 603 to squeeze the second return spring 604 to move up.

Through this operation, the suction force can be transmitted to the feed port 609 through the ventilation groove 404 and the suction groove 410. At this time, the gripping seat 205 drives the drilling rod 401 to rotate again, which can make the drilling rod 401 The collecting seat 601 is driven to rotate, so that the collecting scraper 608 can scrape the surface of the rock and soil layer to collect the rock and soil layer at that depth. Since the feeding port 609 is located at the bottom of the collecting scraper 608, the scraped rock and soil layer can be sucked in from the feeding port 609. Through the above operation, the equipment can flexibly and conveniently collect rock and soil samples of different depths. At the same time, thanks to this design, when the collected rock and soil layer samples are confused, the equipment can quickly and conveniently perform a secondary collection of rock and soil layer samples of the confused depth. The collected rock and soil layer samples will enter the collection inner box 304 due to the suction force. The use of the filter cloth layer 318 can prevent the rock and soil from entering the suction pump 301. After the rock and soil samples are collected, the third motor 312 works to drive the docking plate 313 to rotate.The docking plate 313 is engaged with the engaging groove 306 of the collection inner box 304 through the docking pile 314, so that the collection inner box 304 can rotate synchronously with the docking plate 313. After the collection inner box 304 rotates, the through groove 305 can be covered by the collection outer box 303. At this time, the suction pump 301 continues to work, and the electric control valve 308 is opened. The suction force can be transmitted to the inside of the suction chamber 309 through the second suction pipe 307. After the air in the suction chamber 309 is sucked out, the piston seat 310 will be displaced due to the pressure difference and the adsorption force, so that the piston seat 310 can move up in the suction chamber 309. After the piston seat 310 moves up, it can The rock and soil samples collected are squeezed toward the docking plate 313, so that the soft rock and soil layer can be squeezed into a soil cake. After the sample is squeezed into a soil cake, the electric push rod 311 drives the third electric motor 312 to move upward, so that the docking plate 313 can be separated from the collection inner box 304, which makes it convenient for the staff to take out the soil cake, thereby facilitating the subsequent detection of soil layer samples. Through the above operation, the equipment can rely on suction force to achieve convenient soil layer sample collection and sample aggregation compression, which can avoid the loosening of the collected samples, which is not conducive to detection. At the same time, compressing the rock and soil into a soil cake can also effectively prevent the rock and soil from remaining inside the collection inner box 304, resulting in the occurrence of rock and soil sample confusion.

[0022] In summary, when using the rock and soil detection device for geological survey, the staff first moves the device to the top of the rock and soil layer to be collected, so that the bottom panel 101 can contact the ground. At this time, the staff screws the positioning drill bit 109 into the soil layer, so that the bottom panel 101 can be stably fixed to the ground, which can ensure the stability of the device during the collection process. When the device collects rock and soil on a non-planar terrain, the first motor 106 works to make the first driving gear 107 mesh with the meshing teeth 105 at the outer end of the steering seat 104 and rotate, which allows the steering seat 104 to pass through the meshing teeth 105 at the outer end of the steering seat 104. The workbench 108 is rotated by the steering shaft 103. With this design, the orientation of the workbench 108 can be changed. When the device is on an inclined ground, the orientation of the workbench 108 can be adjusted so that the drilling rod 401 can always be kept in a vertical downward position during the drilling process, which can improve the drilling stability of the device. At the same time, this also enables the device to adapt to various non-horizontal drilling operations. In addition, thanks to the meshing of the first driving gear 107 and the meshing teeth 105, the workbench 108 can maintain a stable rotation angle after stopping rotation, which can avoid changes in the tilt angle during the drilling process. Then, after the position adjustment of the workbench 108 is completed, the staff will dock the drilling rod 401 to be drilled with the gripping seat 205, and the outer contour size of the drilling rod 401 matches the inner contour size of the gripping seat 205, so that the gripping seat 205 can stably fix the drilling rod 401. After the two are connected, the second motor 208 works, so that the second driving gear 209 can drive the driven gear 206 at the outer end of the gripping seat 205 to rotate, so that the gripping seat 205 can rotate inside the bearing connection seat 204. During the rotation process, the gripping seat 205 can transmit the rotational force to the drill bit 5 at the bottom end of the drilling rod 401. At this time, the hydraulic cylinder 202 drives the lower pressure plate 203 to move downward, so that the gripping seat 205 can drive the drilling rod 401 to move downward synchronously. Because the connection frame 207 connects the lower pressure plate 203 and the second motor 208, the second motor 208 can also move downward synchronously, so that the drill bit 5 can drill into the soil layer to achieve drilling of the soil layer. Then, after the drilling rod 401 is completely drilled into the soil layer, the hydraulic cylinder 202 drives the gripping seat 205 to move upward and separate from the drilling rod 401. The staff connects the new drilling rod 401 with the gripping seat 205 again, and makes the connecting pile 405 of the new drilling rod 401 dock with the connecting groove 403 of the drilling rod 401 in the soil layer, so that the two drilling rods 401 can be docked. At this time, the hydraulic cylinder 202 drives the gripping seat 205 to move downward again, so that the drilling rod 401 can be drilled into a deeper soil layer, which enables the equipment to realize rock and soil collection in a deeper soil layer; After the drilling rod 401 has drilled into the soil layer at a specified depth, the staff separates the gripping seat 205 from the drilling rod 401, and can sleeve the collection seat 601 on the outer end of the drilling rod 401. After the collection seat 601 and the drilling rod 401 are sleeved, the electric-controlled roller 610 can be inserted into the slide groove 402 of the drilling rod 401. At this time, the electric-controlled roller 610 rolls, which can drive the collection seat 601 to move along the drilling rod 401, so that the collection seat 601 can be flexibly moved to soil layers of different depths. After moving to the soil layer at a specified depth, the internal electromagnet 602 will be energized, and the electromagnetic force of the electromagnet 602 can be transmitted to the magnetic pile 406 of the drilling rod 401. After the magnetic pile 406 generates magnetic force, it can attract the first armature 407 to adsorb and squeeze the first return spring 408. The first armature 407 is fixed to the sealing block 409, so that the sealing block 409 can move up synchronously. The sealing block 409 moves up and moves away from the inside of the suction groove 410, so that the suction groove 410 can be opened and connected to the feed port 609. Then, the magnetic force of the electromagnet 602 can attract the second armature 603, so that the second armature 603 can squeeze the second return spring 604 to move upward. During the upward movement of the second armature 603, the push block 605 can be driven to move upward synchronously and squeeze the displacement block 606, so that the displacement block 606 can squeeze the third return spring 607 to drive the collection scraper 608 to move outward, so that the collection scraper 608 can extend and contact the rock and soil layer. The suction pump 301 works, and the suction force can be transmitted to the inside of the ventilation pipe 315 through the through groove 305 of the collection inner box 304, and the ventilation pipe 315 can be connected with the gripping seat 205 by stretching the hose 316 and rotating the butt joint 317, and the gripping seat 205 can be connected with the drilling rod 40 1 is connected to the ventilation groove 404 inside. Through this operation, the suction force can be transmitted to the feed port 609 through the ventilation groove 404 and the suction groove 410. At this time, the gripping seat 205 drives the drilling rod 401 to rotate again, and the drilling rod 401 can drive the collection seat 601 to rotate, so that the collection scraper 608 can scrape the surface of the rock and soil layer to collect the rock and soil layer at this depth. Because the feed port 609 is located at the bottom of the collection scraper 608, the scraped rock and soil layer can be sucked from the feed port 609. Through the above operation, the equipment can flexibly and conveniently collect soil samples of rock and soil layers of different depths. At the same time, thanks to this design, when the collected rock and soil layer samples are confused, the equipment can quickly and conveniently perform secondary collection of rock and soil layer samples of the confused depth again; The rock and soil layer samples collected at last will enter the interior of the collection inner box 304 due to the suction force. The use of the filter cloth layer 318 can prevent the rock and soil from entering the interior of the suction pump 301. After the rock and soil samples are collected, the third motor 312 works to drive the docking plate 313 to rotate. The docking plate 313 is engaged with the connecting groove 306 of the collection inner box 304 through the docking pile 314, so that the collection inner box 304 can rotate synchronously with the docking plate 313. After the collection inner box 304 rotates, the through groove 305 can be covered by the collection outer box 303. At this time, the suction pump 301 continues to work, and the electric control valve 308 is opened. The suction force can be transmitted to the interior of the suction chamber 309 through the second suction pipe 307. After the air inside the suction chamber 309 is sucked out, the piston seat 310 will be displaced due to the pressure difference and the adsorption force. This allows the piston seat 310 to move upward inside the suction chamber 309. After moving upward, the piston seat 310 can squeeze the rock and soil samples collected inside the collection inner box 304 toward the docking plate 313, which allows the soft rock and soil layer to be squeezed into a soil cake. After the sample is squeezed into a soil cake, the electric push rod 311 drives the third electric motor 312 to move upward, which can separate the docking plate 313 from the collection inner box 304, allowing the staff to easily take out the soil cake, thereby facilitating the subsequent detection of soil layer samples. Through the above operations, the equipment can rely on suction force to achieve convenient soil layer sample collection and sample aggregation and compression, which can avoid the loosening of the collected samples that is not conducive to detection. At the same time, compressing the rock and soil into soil cakes can also effectively avoid the rock and soil remaining inside the collection inner box 304, resulting in confusion of rock and soil samples.
