Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling, and more specifically, to a soil sampling device and an operation method for land resource detection. Background Art

[0002] Chinese patent document (CN119374956A) discloses a soil sampling device for forestry surveying and mapping, which states in the specification that "an outer cylinder and an inner rod, and a protection mechanism for the inner side wall of the tunnel is provided on the outer side of the inner rod, and the protection mechanism for the inner side wall of the tunnel includes a mounting sleeve fixedly connected to the outer side wall of the inner rod. The outer side wall of the mounting sleeve is fixedly connected with adjusting frames at equal intervals, and the inner side walls on both sides of each adjusting frame are fixedly connected with adjusting slide rails. The soil sampling device for forestry surveying and mapping disclosed by the present invention has the effect that during the process of guiding the sampling device into the tunnel through an external lifting mechanism, the hydraulic cylinder three is intermittently adjusted to drive the inner pressing arc plate to extrude towards the inner side wall of the tunnel to complete preliminary extrusion and reinforcement. During the extrusion process, each protruding pressure rod gradually presses into the inner side wall of the tunnel, thereby performing secondary extrusion and reinforcement on the soil on the inner side wall of the tunnel, so that the soil density on the inner side wall of the tunnel gradually increases, reducing the risk of its collapse", however, it is still difficult to quickly sample deeper soil during actual use.

[0003] For the current soil sampling devices on the market, the length of their samplers is usually fixed. When faced with the need to collect soil from different depths, such as collecting soil from deeper or shallower soil layers, operators have to replace sampling cylinders of different specifications. However, this replacement process is quite cumbersome, involving the disassembly and assembly of multiple steps and components, consuming time and energy. Moreover, the installation and disassembly process of the sampling cylinder itself is rather complicated. After the soil is collected, it is also very inconvenient to take out the soil sample from the sampling cylinder. The operation steps are cumbersome, greatly reducing the sampling efficiency. More importantly, due to the cumbersome process of replacing the sampling cylinder and taking out the sample, it is difficult to completely avoid the cross-mixing of soil from different depths during repeated operations. Once the soil from different layers is mixed, the originality and layering of the soil sample are damaged, which will undoubtedly have a serious negative impact on the subsequent soil quality detection, resulting in the detection results being unable to accurately reflect the true characteristics of each soil layer. In view of this, we propose a soil sampling device and an operation method for land resource detection. Summary of the Invention

A coil spring is arranged outside the pin shaft. An extension plate is fixedly connected to the other side of the isolation plate. The isolation plate is hinged in the placement groove through the pin shaft.

[0015] A soil sampling method includes the following steps: S1. Install the splicing mechanism according to the depth required for sampling. S2. After installing the splicing mechanism to an appropriate length, install the drill bit mechanism at the bottom of the splicing mechanism. S3. Grasp the first handle and the second handle and turn on the switch. Drive the splicing mechanism and the drill bit mechanism to operate through the driver to sample the soil. After sampling, take out the device from the ground. S4. Disassemble the drill bit mechanism and then disassemble the splicing mechanism in sequence to obtain a complete soil sample.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention designs a first cylinder assembly, a second cylinder assembly and a mounting assembly. Grasp the first grip and the second grip and turn on the switch, so that the drill bit mechanism fits the ground and presses downwards. At this time, the extrusion assembly will slide within the connection assembly and simultaneously extrude the isolation assembly, causing the isolation assembly to flip. As the extrusion assembly gradually penetrates underground, the soil samples to be collected will be retained within the first cylinder assembly and the second cylinder assembly. After sampling, the device needs to be pulled out of the ground, then the connection assembly is removed from the outside of the bottommost mounting assembly, and then the first cylinder assembly and the second cylinder assembly are disassembled, and finally the two are separated to obtain a complete soil sample. The device adopts a modular splicing method and can quickly extend or shorten its length. After sampling, the disassembly steps can be quickly completed, thereby ensuring the integrity of the soil sample. At the same time, by disassembling the first cylinder assembly and the second cylinder assembly, the mixing of soil samples can be effectively avoided, ensuring the accuracy of the test results.

[0017] 2. The present invention also designs a mounting assembly. When it is necessary to extend the length of the device according to the detection depth, first insert the first splicing cylinder from top to bottom into the card slot outside the second splicing cylinder through the clamping block until it is inserted to the bottommost part to complete the installation of the first splicing cylinder and the second splicing cylinder. Then, insert the installed first splicing cylinder and the second splicing cylinder as a whole outside the upper inserting cylinder, insert the inserting blocks in the upper mounting slots of the first splicing cylinder and the second splicing cylinder into the L-shaped bottom of the sliding slot, and then slide along the sliding slot to the positions of the first slot and the second slot, and then release the first splicing cylinder and the second splicing cylinder. Repeat the operation according to this method to extend the length of the device. In this way, the device can quickly achieve length extension and quickly make adjustments for different usage environments, so as to sample soil samples at deeper positions.

[0018] 3. The present invention also designs an isolation assembly and an extrusion assembly. Since the drill block at the bottommost part will extrude the sliding cylinder and the limiting plate during use, push the limiting plate and then move the extension plate, and finally make the isolation plate flip along the pin shaft. At the same time, the inserting blocks in several first splicing cylinders and second splicing cylinders will enter the first slot along the second slot under the action of pressure. At this time, turn on the switch and continuously press down the device to complete drilling and sampling. After sampling, when the device is pulled out upwards, the outside of the drill block will contact the underground soil. During the upward movement of the connection cylinder, the drill block will pull the sliding cylinder and the limiting plate to move downwards, thereby releasing the extrusion on the extension plate. At this time, the extension plate and the isolation plate gradually reset under the action of the spring force of the coil spring, playing an isolation role at the bottom of the collected soil. When the device collects soil, the isolation plate can fit within the connection cylinder to avoid interfering with the drilling process; after drilling, the isolation plate can quickly reset to complete the bottoming treatment, effectively preventing the collected soil samples from falling off during the process of pulling out the device.

[0021] As Figures 1 to 9 shown, the present invention relates to a soil sampling device and operation method for land resource detection, including a driver 11, a switch 13 and a first grip 12, and further includes, The driving mechanism includes a driver 11, a first grip 12 above the driver 11, a second grip 14 on one side of the driver 11, and a switch 13, wherein the switch 13 is below the first grip 12; and, The splicing mechanism 2 includes a first cylinder assembly 21, a second cylinder assembly 22 connected to the first cylinder assembly 21, and a mounting assembly 23, wherein the mounting assembly 23 is connected below the first cylinder assembly 21 and the second cylinder assembly 22; and, The drill bit mechanism 3 includes a connecting component 31, a pressing component 32 below the connecting component 31, and an isolation component 33, wherein the isolation component 33 is located within the connecting component 31; an installation component 23 is also provided below the driver 11. By designing the first cylinder assembly 21, the second cylinder assembly 22, and the installation component 23, grasping the first grip 12 and the second grip 14 and turning on the switch 13 causes the drill bit mechanism 3 to fit against the ground and press downwards. At this time, the pressing component 32 slides within the connecting component 31 and simultaneously presses the isolation component 33, causing the isolation component 33 to flip. As the pressing component 32 gradually penetrates the ground, the soil sample to be collected will be retained within the first cylinder assembly 21 and the second cylinder assembly 22. After sampling, the device needs to be pulled out of the ground. Subsequently, the connecting component 31 is removed from outside the bottommost installation component 23, and then the first cylinder assembly 21 and the second cylinder assembly 22 are disassembled, and finally the two are separated to obtain a complete soil sample. This device adopts a modular splicing method and can quickly extend or reduce its length. After sampling, the disassembly steps can be quickly completed, thereby ensuring the integrity of the soil sample. At the same time, by disassembling the first cylinder assembly 21 and the second cylinder assembly 22, the mixing of soil samples can be effectively avoided, ensuring the accuracy of the test results.

[0022] In an embodiment of the present invention, the upper part of the driver 11 is fixedly connected to the first grip 12, one side of the driver 11 is fixedly connected to the second grip 14, the lower part of the first grip 12 is fixedly connected to the switch 13, the output end of the switch 13 is electrically connected to the driver 11 through a wire, the output shaft of the driver 11 is fixedly connected to one of the mounting components 23, the number of the first cylinder components 21 and the second cylinder components 22 is several, and several first cylinder components 21 and second cylinder components 22 are clamped with each other. The lower parts of several first cylinder components 21 and several second cylinder components 22 are both fixedly connected with mounting components 23. The first cylinder component 21 and the second cylinder component 22 are clamped outside the mounting component 23 connected to the lower part of the driver 11. The inner wall of the connecting component 31 is slidably connected to the extrusion component 32, the inner wall of the connecting component 31 is clamped with several isolation components 33, and the upper part of the connecting component 31 is clamped outside the mounting component 23 located at the bottom. By inserting the first splicing cylinder 211 and the second splicing cylinder 221 outside the upper inserting cylinder 231 and completing the fixation, the stability of the first splicing cylinder 211 and the second splicing cylinder 221 after installation can be further improved, and the situation that the first splicing cylinder 211 and the second splicing cylinder 221 fall off during the sampling process can be avoided; By designing the first slot 233 and the second slot 234, it is ensured that when the device is pressed down and pulled out from the soil, the insertion block 224 will be located in the first slot 233 and the second slot 234 respectively, and it is ensured that when the driver 11 is running, the insertion block 224 will not slide along the sliding slot 232, so as to ensure the stability of the device after installation.

[0023] In an embodiment of the present invention, the first cylinder assembly 21 includes a first splicing cylinder 211. Two clamping blocks 212 are arranged outside the first splicing cylinder 211. The first splicing cylinder 211 and the second cylinder assembly 22 are clamped with each other. The second cylinder assembly 22 includes a second splicing cylinder 221. A clamping groove 222 is formed outside the second splicing cylinder 221. The first splicing cylinder 211 is clamped outside the second splicing cylinder 221 through the clamping blocks 212. By designing the installation assembly 23, when it is necessary to extend the length of the device according to the detection depth, first insert the first splicing cylinder 211 from top to bottom into the clamping groove 222 outside the second splicing cylinder 221 through the clamping blocks 212 until it is inserted to the bottommost part, completing the installation of the first splicing cylinder 211 and the second splicing cylinder 221. Then, insert the installed first splicing cylinder 211 and the second splicing cylinder 221 as a whole outside the upper inserting cylinder 231, insert the inserting blocks 224 in the upper installation grooves 223 of the first splicing cylinder 211 and the second splicing cylinder 221 into the L-shaped bottom of the sliding groove 232, and then slide along the sliding groove 232 to the positions of the first slot 233 and the second slot 234. Then release the first splicing cylinder 211 and the second splicing cylinder 221. Repeat the operation according to this method to extend the length of the device. In this way, the device can quickly realize the length extension and quickly make adjustments for different use environments, so as to sample the soil samples at deeper positions.

[0024] Installation grooves 223 are formed above both the first splicing cylinder 211 and the second splicing cylinder 221. The installation grooves 223 are annular. Two inserting blocks 224 are fixedly connected to the inner wall of the installation groove 223. A number of elastic telescopic rods 225 are fixedly connected in the installation groove 223, and the tops of the a number of elastic telescopic rods 225 are all fixedly connected with fixed shells 226. Ball bearings 227 are clamped in the fixed shells 226. Since the device is provided with the elastic telescopic rods 225, the fixed shells 226 and the ball bearings 227, when the inserting blocks 224 are inserted into the sliding groove 232, the elastic telescopic rods 225 will contract due to the ball bearings 227 being squeezed by the upper inserting cylinder 231. When the inserting blocks 224 slide to the position of the second slot 234 in the sliding groove 232, the elastic telescopic rods 225 will reversely squeeze the upper inserting cylinder 231, thereby pushing the inserting blocks 224 into the second slot 234. In this way, the stability of the device after installation can be ensured, effectively avoiding the situation of the device loosening and falling off.

[0025] As another embodiment of the present invention, the installation component 23 includes an insertion cylinder 231. A chute 232 is provided on the outer side of the insertion cylinder 231. The chute 232 is L-shaped. A first slot 233 and a second slot 234 are respectively provided above and below the inner wall of the chute 232. The size of the insertion cylinder 231 is adapted to the size of the installation groove 223, and the sizes of the first slot 233 and the second slot 234 are both adapted to the size of the insertion block 224. The connection component 31 includes a connection cylinder 311. A groove 312 is provided above the connection cylinder 311. Four connection blocks 313 are fixedly connected in the groove 312. A limiting chute 314 is provided below the connection cylinder 311. Four placement grooves 315 are provided on the inner wall of the limiting chute 314. The isolation component 33 is snap-connected in the placement groove 315. The extrusion component 32 is slidably connected in the limiting chute 314. By designing the isolation component 33 and the extrusion component 32, since the drill block 322 at the bottom will extrude the sliding cylinder 321 and the limiting plate 323 during use, the limiting plate 323 is pushed to move the extension plate 333, and finally the isolation plate 331 is flipped along the pin shaft 332. At the same time, the insertion blocks 224 in a plurality of first splicing cylinders 211 and second splicing cylinders 221 will enter the first slot 233 along the second slot 234 under the action of pressure. At this time, the switch 13 is turned on and the device is continuously squeezed downward to complete the drilling and sampling. After the sampling is completed, when the device is pulled out upward, the outside of the drill block 322 will contact the underground soil. During the upward movement of the connection cylinder 311, the drill block 322 will pull the sliding cylinder 321 and the limiting plate 323 to move downward, thereby releasing the extrusion on the extension plate 333. At this time, the extension plate 333 and the isolation plate 331 gradually reset under the action of the elastic force of the coil spring 334, playing an isolation role at the bottom of the collected soil. When the device collects soil, the isolation plate 331 can fit in the connection cylinder 311 to avoid interfering with the drilling process; after the drilling is completed, the isolation plate 331 can quickly reset to complete the bottom handling, effectively preventing the collected soil sample from falling off during the process of pulling out the device.

[0026] As another embodiment of the present invention, the extrusion assembly 32 includes a sliding cylinder 321, and a plurality of drilling blocks 322 are fixedly connected to the lower part of the sliding cylinder 321. A limiting plate 323 is fixedly connected to the upper part of the sliding cylinder 321, and the limiting plate 323 is slidably connected in the limiting chute 314. The isolation assembly 33 includes an isolation plate 331. The lower part of the isolation plate 331 is arc-shaped. A pin shaft 332 is fixedly connected to the lower part of the isolation plate 331. A coil spring 334 is arranged outside the pin shaft 332. An extension plate 333 is fixedly connected to the other side of the isolation plate 331. The isolation plate 331 is hinged in the placement groove 315 through the pin shaft 332. After the soil sample is collected, it is necessary to slide the connection block 313 in the connection cylinder 311 along the chute 232 outside the bottommost insertion cylinder 231, and then pull out the connection cylinder 311. Then, separate the first splicing cylinder 211 and the second splicing cylinder 221 from the upper insertion cylinder 231 in turn, and then disassemble the first splicing cylinder 211 and the second splicing cylinder 221 up and down, so that the first splicing cylinder 211 and the second splicing cylinder 221 can be separated from the surface of the soil sample. By performing such operations after the soil sample is collected, the integrity of the soil sample can be ensured, and multiple disassembly can effectively avoid the mixing of the soil sample.

[0027] Working principle: This embodiment provides a soil sampling device and an operation method for land resource detection. When in use, grasp the first grip 12 and the second grip 14 and turn on the switch 13, so that the drill bit mechanism 3 fits the ground and presses downward. At this time, the extrusion assembly 32 will slide in the connection assembly 31, and at the same time, synchronously squeeze the isolation assembly 33 to make the isolation assembly 33 flip. As the extrusion assembly 32 gradually penetrates underground, the soil sample to be collected will be retained in the first cylinder assembly 21 and the second cylinder assembly 22. After sampling, it is necessary to pull the device out of the ground, then remove the connection assembly 31 from the outside of the bottommost installation assembly 23, and then disassemble the first cylinder assembly 21 and the second cylinder assembly 22, and finally separate the two to obtain a complete soil sample; When it is necessary to extend the length of the device according to the detection depth, insert the first splicing cylinder 211 from top to bottom into the card slot 222 outside the second splicing cylinder 221 through the card block 212 until it is inserted into the bottommost part, so that the installation of the first splicing cylinder 211 and the second splicing cylinder 221 is completed. Then, insert the installed first splicing cylinder 211 and the second splicing cylinder 221 as a whole outside the upper insertion cylinder 231, insert the insertion block 224 in the installation groove 223 above the first splicing cylinder 211 and the second splicing cylinder 221 into the L-shaped bottom of the chute 232, and then slide along the chute 232 to the positions of the first slot 233 and the second slot 234, and then release the first splicing cylinder 211 and the second splicing cylinder 221. Repeat the operation according to this method to extend the length of the device; During use, the drill block 322 at the bottommost part will squeeze the sliding cylinder 321 and the limiting plate 323, push the limiting plate 323 and then drive the extension plate 333, causing the isolation plate 331 to flip along the pin shaft 332. At the same time, the insertion blocks 224 in a number of the first splicing cylinders 211 and the second splicing cylinders 221 will, under the action of pressure, enter the first slots 233 along the second slots 234. At this time, turn on the switch 13 and continuously squeeze the device downward, and the drilling and sampling can be completed. After the sampling is completed, when pulling out the device upward, the outside of the drill block 322 will contact the underground soil. During the upward movement of the connecting cylinder 311, the drill block 322 will pull the sliding cylinder 321 and the limiting plate 323 downward, thereby relieving the extrusion on the extension plate 333. At this time, the extension plate 333 and the isolation plate 331 gradually reset under the action of the elastic force of the coil spring 334, playing an isolation role on the bottom of the collected soil; After the soil sample collection is completed, the connecting block 313 in the connecting cylinder 311 needs to be slid along the chute 232 outside the bottommost insertion cylinder 231, and then the connecting cylinder 311 is pulled out. Then, the first splicing cylinder 211 and the second splicing cylinder 221 are separated from the upper insertion cylinder 231 in sequence, and then the two are disassembled up and down, so that the first splicing cylinder 211 and the second splicing cylinder 221 can be separated from the surface of the soil sample.
