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, 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 of both sides of each adjusting frame are fixedly connected with adjusting sliding rails. The soil sampling device for forestry surveying and mapping disclosed by the present invention has the effect that during the process of introducing 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 squeeze towards the inner side wall of the tunnel to complete preliminary squeezing and reinforcement. During the squeezing process, each protruding pressing rod gradually presses into the inner side wall of the tunnel, so as to perform secondary squeezing and reinforcement on the soil on the inner side wall of the tunnel, gradually increasing the density of the soil on the inner side wall of the tunnel and 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 the sampler is usually fixed. When faced with the need to collect soil from different depths, such as collecting soil from deeper or shallower soil layers, the operator has 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;

[0028] The isolation plate is hinged in the placement groove through the pin shaft.

[0029] A soil sampling method includes the following steps:

[0030] S1. Install the splicing mechanism according to the depth required for sampling;

[0031] S2. After installing the splicing mechanism to a suitable length, install the drill bit mechanism at the bottom of the splicing mechanism;

[0032] S3. Grasp the first grip and the second grip and turn on the switch. Drive the splicing mechanism and the drill bit mechanism to operate through the driver to take soil samples. After sampling, take the device out of the ground;

[0033] S4. Disassemble the drill bit mechanism and then disassemble the splicing mechanism in sequence to obtain a complete soil sample.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] 1. By designing the first cylinder assembly, the second cylinder assembly and the installation 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 down. At this time, the extrusion assembly will slide in the connection assembly and synchronously extrude the isolation assembly, causing the isolation assembly to flip. As the extrusion assembly gradually penetrates into the ground, the soil sample to be collected will be retained in the first cylinder assembly and the second cylinder assembly. After sampling, the device needs to be pulled out of the ground. Then, remove the connection assembly from the outside of the bottommost installation assembly, and then disassemble the first cylinder assembly and the second cylinder assembly, and finally separate the two to obtain a complete soil sample. The device adopts a modular splicing method, which can quickly extend or shorten the 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.

[0036] 2. The present invention also designs the installation assembly. When it is necessary to extend the length of the device according to the detection depth, first insert the first splicing cylinder into the card slot outside the second splicing cylinder from top to bottom through the card 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 insertion cylinder, insert the insertion blocks in the upper installation 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 use environments, so as to sample the soil samples at deeper positions.

[0037] 3. The present invention also designs an isolation component and an extrusion component. When in use, the drill block at the bottom will extrude the sliding cylinder and the limit plate, pushing the limit plate and then moving the extension plate. Eventually, the isolation plate will flip along the pin shaft. At the same time, the insertion 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 squeeze the device downward to complete the drilling and sampling. After sampling, when pulling out the device upward, the outside of the drill block will contact the underground soil. During the upward movement of the connecting cylinder, the drill block will pull the sliding cylinder and the limit plate downward, 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, playing an isolation role at the bottom of the collected soil. When the device collects soil, the isolation plate can fit inside the connecting cylinder to avoid interfering with the drilling process. After drilling, the isolation plate 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.

[0058] As Figures 1 to 9 shown, a soil sampling device and operation method for land resource detection according to the present invention include a driver 11, a switch 13 and a first grip 12, and further include,

[0059] A driving mechanism, including a driver 11, a first grip 12 located above the driver 11, a second grip 14 located on one side of the driver 11, and a switch 13, wherein the switch 13 is located below the first grip 12; and,

[0060] A splicing mechanism 2, including a first cylinder component 21, a second cylinder component 22 connected to the first cylinder component 21, and a mounting component 23, wherein the mounting component 23 is connected below the first cylinder component 21 and the second cylinder component 22; and,

[0061] The drill bit mechanism 3 includes a connection component 31, an extrusion component 32 located below the connection component 31, and an isolation component 33. Among them, the isolation component 33 is located within the connection component 31. An installation component 23 is also provided below the driver 11. By designing the first cylinder component 21, the second cylinder component 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 downward. At this time, the extrusion component 32 will slide within the connection component 31 and simultaneously press the isolation component 33, causing the isolation component 33 to flip. As the extrusion component 32 gradually penetrates into the ground, the soil sample to be collected will be retained within the first cylinder component 21 and the second cylinder component 22. After sampling, the device needs to be pulled out of the ground. Subsequently, the connection component 31 is removed from outside the lowermost installation component 23, and then the first cylinder component 21 and the second cylinder component 22 are disassembled. Finally, they are separated to obtain a complete soil sample. This device uses a modular splicing method and can quickly extend or shorten its length. After sampling, the disassembly steps can be quickly completed, thus ensuring the integrity of the soil sample. At the same time, by disassembling the first cylinder component 21 and the second cylinder component 22, the mixing of soil samples can be effectively avoided, ensuring the accuracy of the test results.

[0062] 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 installation 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 mutually clamped. Installation components 23 are fixedly connected below several first cylinder components 21 and several second cylinder components 22. The first cylinder component 21 and the second cylinder component 22 are clamped outside the installation component 23 connected below the driver 11. The inner wall of the connection component 31 is slidably connected to the extrusion component 32, the inner wall of the connection component 31 is clamped with several isolation components 33, and the upper part of the connection component 31 is clamped outside the lowermost installation component 23. By inserting the first splicing cylinder 211 and the second splicing cylinder 221 outside the upper insertion 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, avoiding the situation where the first splicing cylinder 211 and the second splicing cylinder 221 fall off during the sampling process.

[0063] By designing the first slot 233 and the second slot 234, it is ensured that when the device is pressed down and pulled out upward from the soil, the plug 224 will be located in the first slot 233 and the second slot 234 respectively, ensuring that the plug 224 will not slide along the chute 232 when the driver 11 is operating, and guaranteeing the stability of the device after installation.

[0064] 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 is clamped with the second cylinder assembly 22. 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 through the clamping blocks 212 into the clamping groove 222 outside the second splicing cylinder 221 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 assembled first splicing cylinder 211 and second splicing cylinder 221 as a whole outside the upper inserting cylinder 231, insert the plugs 224 in the installation grooves 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. In this way, the device can quickly realize the length extension, quickly make adjustments for different use environments, and thus sample the soil samples at deeper positions.

[0065] 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 plugs 224 are fixedly connected to the inner wall of the installation grooves 223. A number of elastic telescopic rods 225 are fixedly connected in the installation grooves 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 plugs 224 are inserted into the chute 232, the elastic telescopic rods 225 will contract due to the ball bearings 227 being squeezed by the upper inserting cylinder 231. When the plugs 224 slide in the chute 232 to the position of the second slot 234, the elastic telescopic rods 225 will reversely squeeze the upper inserting cylinder 231, and then push the plugs 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.

[0066] As another embodiment of the present invention, the installation component 23 includes an insertion cylinder 231. A chute 232 is provided outside 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 limit chute 314 is provided below the connection cylinder 311. Four placement grooves 315 are provided on the inner wall of the limit chute 314. The isolation component 33 is snap-fitted in the placement groove 315. The extrusion component 32 is slidably connected in the limit chute 314. By designing the isolation component 33 and the extrusion component 32, since the drill block 322 at the bottom will squeeze the sliding cylinder 321 and the limit plate 323 during use, the limit 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 limit 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 bottoming process, effectively preventing the collected soil sample from falling off during the process of pulling out the device.

[0067] As another embodiment of the present invention, the extrusion assembly 32 includes a sliding cylinder 321. 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. 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, the connection block 313 in the connection cylinder 311 needs to be slid along the chute 232 outside the bottommost insertion cylinder 231, and then the connection cylinder 311 is pulled out. Then, the first splicing cylinder 211 and the second splicing cylinder 221 are successively separated from the upper insertion cylinder 231, and then the first splicing cylinder 211 and the second splicing cylinder 221 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. By performing such operations after the soil sample is collected, the integrity of the soil sample can be ensured, and multiple disassembly can effectively prevent the soil sample from being mixed.

[0068] 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, the isolation assembly 33 is synchronously extruded 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, the device needs to be pulled out of the ground, then the connection assembly 31 is removed from the outside of the bottommost installation assembly 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.

[0069] 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 to 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.

[0070] In 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 to complete the drilling and sampling. 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 releasing the extrusion on the extension plate 333. At this time, the extension plate 333 and the isolation plate 331 gradually reset under the elastic force of the coil spring 334, playing an isolation role on the bottom of the collected soil;

[0071] 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.
