Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, and in particular to a segmented borehole sampling device for topographic geological exploration. Background Technology

[0002] Drilling is a common geological exploration method used to observe the geological structure of strata. The core samples obtained from the drilling are used to identify and classify the strata below the surface. Sampling can be carried out along the depth of the borehole, which can obtain deep geological data.

[0003] Chinese utility model patent CN214952287U discloses a drilling and sampling device for highway engineering, comprising a base, a telescopic rod fixedly connected inside the base, and a connecting seat fixedly connected to the telescopic end of the telescopic rod extending to the outside of the base. The connecting seat and the base are movably connected by a shock-absorbing spring, and a first connecting plate is provided on the inner side of the base. This drilling and sampling device for highway engineering utilizes shock-absorbing springs to reduce the impact and vibration on the equipment, ensuring stability during drilling and preventing drill bit deviation. It also uses weight blocks to increase the weight of the equipment, facilitating stable operation and greatly improving its practicality. Bolts are used to install and fix the drill bit to the equipment, facilitating drill bit disassembly and replacement. Furthermore, the inclusion of a water tank and pump allows water to be drawn from the tank during drilling to cool the drill bit, significantly improving the working efficiency. However, this device cannot sample samples from different layers, cannot splice drill bits, and has limited drilling depth.

[0004] Existing drilling equipment has limited sampling depth and uses a single sampling tube, making it inconvenient to distinguish samples from different layers. Therefore, a segmented drilling and sampling device for topographic and geological exploration is needed. This device can perform segmented sampling. The segmented drilling method can not only drill deeper soil samples, but also ensure that the extracted samples are clearly layered, resulting in more accurate data and more valuable reference value during testing. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a segmented drilling and sampling device for topographic and geological exploration. This device can perform segmented sampling. The segmented drilling method not only allows for drilling into deeper soil layers, but also ensures that the extracted samples are clearly layered, resulting in more accurate data and greater reference value during testing.

[0006] The technical solution used in this invention is: a segmented drilling and sampling device for topographic and geological exploration, including a feeding auxiliary mechanism, an intermittent feeding mechanism, and a sampling power mechanism;

[0007] The intermittent feeding mechanism is mounted on the vehicle body, and the sampling power mechanism is mounted above the intermittent feeding mechanism;

[0008] The aforementioned loading auxiliary mechanism includes: a vehicle body, outriggers, an extension rod, a hydraulic rod, and a pallet;

[0009] The outriggers are four in number and are fixedly installed at the four corners of the vehicle body; the extension is fixedly installed on the side of the vehicle body; the lower end of the hydraulic rod is rotatably installed on the hub on the extension; the upper end of the hydraulic rod is rotatably installed on the hinge under the tray; and the tray is rotatably installed on the shaft on the extension.

[0010] Preferably, the intermittent feeding mechanism includes: bracket A, support plate, docking frame, turntable, rotating shaft, chuck, drill barrel, dial plate, lever, and servo motor A;

[0011] The bracket A is fixedly installed on the vehicle body, the support plate is fixedly installed between the brackets A, and the docking frame is fixedly installed at the lower end of the bracket B; the turntable is fixedly installed at the lower end of the rotating shaft, the rotating shaft is rotatably installed in the circular hole on the vehicle body, the chuck is fixedly installed at the upper end of the rotating shaft, and several drill barrels are clamped in the chuck's slot; the dial is rotatably installed on the sleeve on the vehicle body, and the lever is fixedly installed on the dial; the servo motor A is fixedly installed on the vehicle body, and the motor gear of the servo motor A meshes with the spur gear on the dial.

[0012] Preferably, the intermittent feeding mechanism includes: a push plate, an electric cylinder A, a clamping block, and an electric cylinder B;

[0013] The push plate is slidably installed on the slide groove of the support plate, and the outer end of the push plate is fixedly connected to the piston rod of the electric cylinder A. The cylinder body of the electric cylinder A is fixedly installed on the bracket B. The locking block is slidably installed in the slide groove of the docking frame, and the locking block is fixedly connected to the piston rod of the electric cylinder B. The cylinder body of the electric cylinder B is fixedly installed on the docking frame.

[0014] Preferably, the sampling power mechanism includes: bracket B, slider, large gear, drill bit, lead screw, driven wheel, belt, servo motor B, long rod, driven gear, and servo motor C;

[0015] The lower end of bracket B is fixedly mounted on the support plate and simultaneously fixedly connected to the docking frame. The slider is slidably mounted on the long rod, which is fixedly mounted on bracket B. The slider is threadedly connected to two lead screws, each with a driven wheel fixedly mounted on its upper end. The two driven wheels are connected by a belt. A small gear is fixedly mounted on the upper end of one of the lead screws, meshing with the motor gear of servo motor B. Servo motor B is fixedly mounted on bracket B. Two driven gears are rotatably mounted on sleeves at both ends of the slider, meshing with the motor gears of two servo motors C, which are both fixedly mounted on the slider. The driven gears mesh with a large gear, which is fixedly connected to the drill bit in the drill barrel. The drill bit is rotatably mounted in the central hole of the slider, and its lower end can dock with the upper end of the drill barrel.

[0016] Preferably, the drill barrel is made of high-speed steel (HSS), a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel and high-speed steel, commonly known as white steel. High-speed steel is a material that is tougher and easier to cut than ordinary metals. High-speed steel has better toughness, strength and heat resistance than carbon tool steel, and its cutting speed is much higher than that of carbon tool steel (iron-carbon alloy), hence the name high-speed steel. Carbide has even better performance than high-speed steel, and its cutting speed can be increased by 2-3 times.

[0018] (1) When using this invention, a segmented sampling method can be used, and the lower end of each segment of the drill barrel can be connected to the upper end of the slot, so that each segment of the drill barrel can be seamlessly connected.

[0019] (2) When the present invention is used, the electric cylinder A drives the push plate, which pushes the drill barrel on the chuck to the chuck block. The servo motor A drives the dial to rotate, which in turn drives the turntable to rotate intermittently, so that the drill barrel on the chuck is replenished intermittently, realizing the full automation of material feeding, which is very convenient.

[0020] (3) When using this invention, after sampling is completed, the sample in each section of the drill barrel is taken out and stored separately. This allows for precise detection of the sample at each level, obtaining accurate experimental data, which is of greater reference value. Attached Figure Description

Detailed Implementation

[0029] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0031] Implementation, for example Figure 1-11As shown, a segmented drilling and sampling device for topographic and geological exploration includes a feeding auxiliary mechanism 1, an intermittent feeding mechanism 2, and a sampling power mechanism 3. The intermittent feeding mechanism 2 is installed on the vehicle body 101, and the sampling power mechanism 3 is installed above the intermittent feeding mechanism 2. The feeding auxiliary mechanism 1 is used to provide support during feeding. The intermittent feeding mechanism 2 is used to intermittently push the drill barrel 207 to below the drill bit 304, waiting for drilling. The sampling power mechanism 3 is used to drill each section of the drill barrel 207 downwards to collect samples.

[0032] In one optional embodiment of the present invention, such as Figure 4 , Figure 5 As shown, the loading auxiliary mechanism 1 includes: a vehicle body 101, outriggers 102, an extension 103, a hydraulic rod 104, and a pallet 105;

[0033] Four outriggers 102 are fixedly installed at the four corners of the vehicle body 101. The outriggers 102 can be extended and retracted to raise or lower the equipment. The extension 103 is fixedly installed on the side of the vehicle body 101. The lower end of the hydraulic rod 104 is rotatably installed on the hub on the extension 103, and the upper end of the hydraulic rod 104 is rotatably installed on the hinge under the tray 105. The tray 105 is rotatably installed on the shaft on the extension 103.

[0034] Specifically, before using the equipment, it is necessary to replenish the material in advance. First, place the drill barrel 207 in the slot on the extension 103. Next, the hydraulic rod 104 extends and retracts to lift the tray 105. The tray 105 lifts the drill barrel 207, thereby lifting the drill barrel 207 to the slot of the chuck 206. Then, manually push the drill barrel 207 into the slot.

[0035] In one optional embodiment of the present invention, such as Figure 4 , Figure 6 , Figure 7 As shown, the intermittent feeding mechanism 2 includes: bracket A201, support plate 202, docking frame 203, turntable 204, rotating shaft 205, chuck 206, drill barrel 207, dial 208, lever 209, and servo motor A210.

[0036] A bracket A201 is fixedly installed on the vehicle body 101, a support plate 202 is fixedly installed between the brackets A201, a docking frame 203 is fixedly installed at the lower end of the bracket B301, and the docking frame 203 is provided with a slide for docking with the slot of the chuck 206; a turntable 204 is fixedly installed at the lower end of the rotating shaft 205, the rotating shaft 205 is rotatably installed in a circular hole on the vehicle body 101, the chuck 206 is fixedly installed at the upper end of the rotating shaft 205, and several drill barrels 207 are clamped in the slot of the chuck 206; a dial 208 is rotatably installed on a sleeve on the vehicle body 101, and a lever 209 is fixedly installed on the dial 208. Each time the dial 208 rotates one revolution, it can move the short shafts on the turntables 204 at both ends, thereby driving the turntables 204 at both ends to rotate one increment; a servo motor A210 is fixedly installed on the vehicle body 101, and the motor gear of the servo motor A210 meshes with the spur gear on the dial 208.

[0037] In one optional embodiment of the present invention, such as Figure 4 , Figure 8 As shown, the intermittent feeding mechanism 2 includes: a push plate 211, an electric cylinder A 212, a clamping block 213, and an electric cylinder B 214;

[0038] Push plate 211 is slidably installed on the groove of support plate 202. The outer end of push plate 211 is fixedly connected to the piston rod of electric cylinder A212. The cylinder body of electric cylinder A212 is fixedly installed on bracket B301. Electric cylinder A212 drives push plate 211 to slide. The actuating rod at the lower end of push plate 211 pushes drill barrel 207 between two locking blocks 213. Locking block 213 is slidably installed in the groove of docking frame 203. Locking block 213 is fixedly connected to the piston rod of electric cylinder B214. The cylinder body of electric cylinder B214 is fixedly installed on docking frame 203.

[0039] Specifically, once all the drill cylinders 207 are installed on the chucks 206, the drilling and sampling work begins. First, the electric cylinder A212 on the right side is activated, causing the push plate 211 on the right side to slide inward. The push plate 211 pushes the drill cylinder 207 inward until it slides between the blocks 213. Next, the sampling power mechanism 3 drills the drill cylinder 207 into the ground. Next, the electric cylinder A212 on the left side is activated, causing the push plate 211 on the left side to slide inward, pushing another drill cylinder 207 inward. This process is repeated, pushing the drill cylinders 207 on both chucks 206 to the blocks 213. When there are no drill cylinders 207 in the path of the push plate 211, the servo motor A210 is activated, causing the dial 208 to rotate one revolution. The lever 209 moves the turntables 204 on both sides to rotate one increment, thereby adding drill cylinders 207 to the path of the push plate 211. This process is repeated until the sampling depth is reached.

[0040] In one optional embodiment of the present invention, such as Figure 10As shown, the sampling power mechanism 3 includes: bracket B301, slider 302, large gear 303, drill bit 304, lead screw 305, driven wheel 306, belt 307, servo motor B308, long rod 309, driven gear 310, and servo motor C311.

[0041] The lower end of bracket B301 is fixedly mounted on support plate 202 and also fixedly connected to docking frame 203. Slider 302 is slidably mounted on long rod 309, which is fixedly mounted on bracket B301. Slider 302 is threadedly connected to two lead screws 305. Rotation of the lead screws 305 drives slider 302 to move up and down, thus achieving lifting and lowering of slider 302. Driven wheel 306 is fixedly mounted on the upper end of lead screw 305. The two driven wheels 306 are connected by belt 307. A small gear is fixedly mounted on the upper end of one lead screw 305, and the small gear meshes with the motor gear of servo motor B308. The servo motor B308 is fixedly mounted on the bracket B301; two driven gears 310 are rotatably mounted on the sleeves at both ends of the slider 302, and the two driven gears 310 mesh with the motor gears of the two servo motors C311 respectively. Both servo motors C311 are fixedly mounted on the slider 302. Using two motors can greatly increase the torque of the equipment; the driven gears 310 mesh with the large gear 303, and the large gear 303 is fixedly connected to the drill barrel and drill bit 304. The drill barrel and drill bit 304 are rotatably mounted in the round hole in the middle of the slider 302, and the lower end of the drill barrel and drill bit 304 can be connected to the upper end of the drill barrel 207.

[0042] Specifically, when the pusher plate 211 pushes the drill barrel 207 to the locking block 213, the servo motors B308 and C311 start simultaneously. This drives the slider 302 downwards via the lead screw 305, and simultaneously drives the drill bit 304 to rotate via the large gear 303. When the lower end of the drill bit 304 touches the upper end of the drill barrel 207, the lower end of the drill bit 304 engages in the slot on the upper end of the drill barrel 207, thus connecting them. Next, the electric cylinder B214 starts. The two locking blocks 213 are opened, allowing the drill barrel 207 to move downwards and drill into the ground. Note that only the first drill barrel 207 has threads at the bottom to facilitate drilling into the ground. When the first drill barrel 207 drills into the ground, the drill bit 304 is driven to rotate in the opposite direction and move upwards, thereby disengaging from the upper locking groove of the drill barrel 207. Repeat this step to connect all the drill barrels 207, thereby driving several drill barrels 207 into the ground for sampling.

[0043] After sampling is completed, the process is reversed from the previous steps. Each drill cylinder 207 is brought up, the clamping block 213 clamps the drill cylinder 207, and the push plate 211 pulls the drill cylinder 207 into the slot on the chuck 206. Finally, all the drill cylinders 207 that have completed sampling are returned to the chuck 206. The next step is to take out and preserve the soil from each drill cylinder 207.

[0044] In one optional embodiment of the present invention, such as Figure 11 As shown, the drill barrel 207 is made of high-speed steel (HSS). High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance. It is also known as high-speed tool steel and high-speed steel, and is commonly known as white steel. High-speed steel is a material that is tougher and easier to cut than ordinary metals. High-speed steel has better toughness, strength and heat resistance than carbon tool steel, and its cutting speed is much higher than that of carbon tool steel (iron-carbon alloy), hence the name high-speed steel. Carbide has even better performance than high-speed steel, and its cutting speed can be increased by 2-3 times.

[0045] Working principle: Before using the equipment, it is necessary to replenish the material in advance. First, place the drill cylinder 207 in the slot on the extension 103. Next, the hydraulic rod 104 extends and retracts to lift the tray 105. The tray 105 lifts the drill cylinder 207, thereby lifting the drill cylinder 207 to the slot of the chuck 206. Then, manually push the drill cylinder 207 into the slot.

[0046] Once all the drill barrels 207 are installed on the chuck 206, the drilling and sampling work begins. First, the electric cylinder A212 on the right side is started, which drives the push plate 211 on the right side to slide inward. The push plate 211 pushes the drill barrel 207 to slide inward until it slides between the chuck blocks 213.

[0047] Next, when the push plate 211 pushes the drill barrel 207 to the locking block 213, the servo motors B308 and C311 start simultaneously, driving the slider 302 downward through the lead screw 305, and simultaneously driving the drill barrel drill bit 304 to rotate through the large gear 303. When the lower end of the drill barrel drill bit 304 touches the upper end of the drill barrel 207, the lower end of the drill barrel drill bit 304 will be locked into the slot on the upper end of the drill barrel 207, thus connecting them. Next, the electric cylinder B214 starts, driving the two locking blocks 213 to open, so that the drill barrel 207 can move downward, thus drilling the drill barrel 207 into the ground. At this time, it should be noted that only the lower end of the first drill barrel 207 has threads to facilitate drilling into the ground. When the first drill barrel 207 drills into the ground, the drill barrel drill bit 304 is driven to rotate in the opposite direction and move upward, thus disengaging from the slot on the upper end of the drill barrel 207.

[0048] Next, the electric cylinder A212 on the left is started, which drives the push plate 211 on the left to slide inward, pushing another drill barrel 207 to slide inward. In turn, the drill barrels 207 on the two chucks 206 are pushed to the chuck block 213. When there are no drill barrels 207 in the path of the push plate 211 sliding inward, the servo motor A210 is started, which drives the dial 208 to rotate one revolution. The lever 209 moves the turntables 204 on the left and right sides to rotate one increment, so that the drill barrels 207 are added to the path of the push plate 211.

[0049] Repeat this step to connect all the drill barrels 207, thereby driving several drill barrels 207 into the ground for sampling;

[0050] After sampling is completed, the process is reversed from the previous steps. Each drill cylinder 207 is brought up, the clamping block 213 clamps the drill cylinder 207, and the push plate 211 pulls the drill cylinder 207 into the slot on the chuck 206. Finally, all the drill cylinders 207 that have completed sampling are returned to the chuck 206. The next step is to take out and preserve the soil from each drill cylinder 207.
