Description
Technical Field
[0001] The invention relates to the field of soil sampling equipment, and in particular to a soil sampler and a sampling method based on high-frequency sound waves. Background Art
[0002] At present, traditional rotary, impact and direct-push drilling technologies have problems such as difficulty in drilling, small sampling volume and large disturbance when drilling and sampling in soft strata, sand layers, gravel-containing strata and other strata. High-frequency acoustic drilling technology is a reliable and complete sampling technology that has been reported to achieve in-situ low-disturbance drilling sampling. The high-frequency vibration force it generates can quickly liquefy the soil, thereby reducing friction resistance and ultimately obtaining low-compression ratio samples. At this stage, domestic research on acoustic drilling technology is mainly suitable for soft, medium-hard and hard strata sites, and can obtain complete, continuous and low-disturbance samples. However, in actual soil sampling, soil samplers are generally used to achieve low-disturbance drilling. The main goal is to make progress, but the spatial position accuracy of the sample in the sampling process is not considered, which may cause drilling deviation and lead to poor sample restoration. At the same time, the strong bumps when the soil sampler moves in complex terrain in the field often produce a large horizontal pulling force, which will cause the installation point between the drill guide rail and the fixed body to be subjected to a large horizontal force, resulting in an unstable connection. In addition, the contact points between the vibrating components are often relatively fixed. Single-point vibration greatly increases the stress concentration at the contact part of the conductive component, greatly increasing the probability of damage to the component. Therefore, we propose a soil sampler and sampling method based on high-frequency sound waves to solve the above-mentioned problems. Summary of the invention

[0013] Preferably, a soil sampling method based on high-frequency sound waves comprises the following sampling steps: S1. In actual use, people first drive the walking track wheels through the motor inside the equipment compartment to make the multi-terrain soil sampler move. When taking soil samples, people first lower the hydraulic support feet, and use the hydraulic support feet to make the multi-terrain soil sampler stop steadily at the sampling point, which is convenient for sampling work; S2. After arriving at the sampling point, people start the multi-terrain soil sampler. At the beginning of sampling, the sampling drill rod is first installed at the bottom of the connector by fixing bolts to complete the connection. Then the vibration frame is started. The vibration frame is operated to lift and lower along the guide rail. The vibration frame is lowered to drive the sampling drill rod installed at the bottom of the connector to lower, so that the sampling drill rod is inserted into the soil to achieve sampling. The sampling depth of the sampling drill rod is adjusted by controlling the descending height of the vibration frame. S3. Before sampling, a signal is sent through the reference positioning point to transmit the spatial coordinate information of the current reference point. At this time, the verticality of the side wall of the connector is detected by the infrared sensor installed on the inner side of the mounting ring, and the spatial coordinate information of the reference positioning point is received by the positioning sensor at the bottom of the outer shell, and the spatial coordinate system is checked and calculated to obtain the offset required to adjust the connector to verticality, so as to facilitate people to quickly adjust the multi-terrain soil sampler and the connector to horizontal and vertical; S4. During the sampling drill rod insertion and sampling process, the servo motor inside the vibration frame drives the eccentric rotor to rotate synchronously. When the eccentric rotor rotates, high-frequency vibration waves are generated. The high-frequency vibration waves are transmitted to the connecting column through the contact between the resonance tube and the conduction tube. The vibration waves are evenly transmitted to the sampling drill rod through the conduction between the connecting column and the connecting head, so that the drill rod vibrates at a high frequency while rotating at a high speed, making the drilling and sampling work of the sampling drill rod smoother, and completing the deep sampling work; S5. During sampling, the positioning sensor at the bottom of the outer casing cooperates with the reference positioning point to assist in calculating the depth of the connector and the sampling drill rod, so as to achieve calibration and verification of fixed-depth sampling. The signal generator installed at the bottom of the sampling drill rod interacts with the reference positioning point during the sampling and drilling process to achieve double verification. The signal amplifier ensures that the sampling drill rod still maintains the stability of the signal at a deeper sampling depth. S6. After multiple samplings, people start the reduction motors on the fixed frame one and the fixed frame two, and drive the guide wheel to rotate through the reduction motor on the fixed frame two, and drive the conduction tube to rotate through the friction force of the conduction tube, and drive the rotating frame to rotate through the reduction motor on the fixed frame one, and drive the conduction tube to move up and down through the rotating frame using friction, so as to adjust the contact point between the conduction tube and the resonance tube, thereby effectively avoiding long-term single-point vibration of the conduction tube.
[0014] Compared with the prior art, the present invention has the following beneficial effects: When the multi-terrain soil sampler moves, the cooperation between the damping block and the damping rod can buffer the large horizontal pulling force generated when the multi-terrain soil sampler moves in complex terrain in the field. At the same time, the damping cylinder and the hydraulic buffer rod can further buffer the working vibration of the equipment inside the equipment compartment, so that the direct force transmission between the guide rail and the multi-terrain soil sampler body can be greatly buffered and improved, so that the installation point between the guide rail and the multi-terrain soil sampler body can remain stable, greatly extending the service life of the equipment; After arriving at the sampling point, people can start the multi-terrain soil sampler. At the beginning of sampling, the sampling drill rod is first installed at the bottom of the connector by fixing the bolts to complete the connection. Then the vibration frame is started. The vibration frame can be raised and lowered along the guide rail. By lowering the vibration frame, the sampling drill rod installed at the bottom of the connector can be driven down, so that the sampling drill rod can be inserted into the soil to realize sampling. By controlling the descending height of the vibration frame, the sampling depth of the sampling drill rod can be adjusted, which is conducive to fixed-point and fixed-depth sampling.
[0015] Before sampling, a signal can be sent through the reference positioning point to transmit the spatial coordinate information of the current reference point. At this time, the infrared sensor installed on the inner side of the mounting ring can detect the verticality of the side wall of the connector, and the positioning sensor at the bottom of the outer shell can receive the spatial coordinate information of the reference positioning point, and can check the spatial coordinate system and calculate its own spatial coordinate information, so as to obtain the offset required to adjust the connector to verticality, so that people can quickly adjust the multi-terrain soil sampler and the connector to horizontal and vertical, which can help to ensure the accuracy of subsequent fixed-point sampling.
[0016] During sampling, the positioning sensor at the bottom of the outer casing can cooperate with the reference positioning point to assist in calculating the depth of the connector and the sampling drill rod, thereby realizing the calibration and verification of fixed-depth sampling, which is beneficial to further improve the accuracy of fixed-depth sampling. The signal generator installed at the bottom of the sampling drill rod can interact with the reference positioning point during the sampling and drilling process to realize double verification. The signal amplifier can ensure that the sampling drill rod can still maintain the stability of the signal at a deeper sampling depth, which is beneficial to fixed-depth sampling.
[0017] When sampling, leveling and setting the depth, the stepper motor can be started to drive the threaded rod to rotate, and the threaded rod can drive the connecting block and the ring frame to descend as a whole and separate from the vibration frame. The heavier material of the outer protective shell can use gravity to keep the outer protective shell level, which can effectively reduce the impact of the internal vibration of the vibration frame on the positioning sensor and the infrared sensor. The buffer block installed on the outside of the resonance cylinder can shield and block the vibration waves of the resonance cylinder, further improving the stability of the vibration frame. The magnetic coating inside the outer protective shell can repel the magnetic ring embedded on the outer periphery of the mounting ring, so that the mounting ring is not completely in contact with the inside of the outer protective shell, so that the precise depth and point sampling work can be less disturbed and more stable.
[0018] When not positioned, the stepper motor can drive the threaded rod to reverse, and the threaded rod can drive the connecting block and the ring frame to rise as a whole and embed them into the opening, so as to protect the positioning components at this location. It is suitable for the transfer of multi-terrain soil samplers in complex terrain in the field.
[0019] After multiple samplings, people can start the reduction motors on the fixed frame one and the fixed frame two, and the reduction motor on the fixed frame two can drive the guide wheel to rotate, and the conduction tube can be driven to rotate by friction through the conduction tube, and the reduction motor on the fixed frame one can drive the rotating frame to rotate, and the rotating frame can drive the conduction tube to move up and down by friction, so as to adjust the contact point between the conduction tube and the resonance tube, thereby effectively avoiding long-term single-point vibration of the conduction tube, greatly reducing the probability of damage to the conduction tube, and facilitating practical use.

After reaching the sampling point, people can start the multi-terrain soil sampler 1. At the beginning of sampling, first install the sampling drill rod at the bottom of the connecting head 114 with the fixing bolts to complete the connection, and then start the vibration frame 104. Through the operation of the vibration frame 104, it can be raised and lowered along the guide rail 102. By lowering the vibration frame 104, the sampling drill rod installed at the bottom of the connecting head 114 can be driven The vibration frame 104 is lowered so that the sampling drill rod can be inserted into the soil to perform sampling. The sampling depth of the sampling drill rod can be adjusted by controlling the descending height of the vibration frame 104, which is beneficial to fixed-point and fixed-depth sampling. In the process of inserting the sampling drill rod for sampling, the servo motor inside the vibration frame 104 can drive the eccentric rotor 129 to rotate synchronously. When the eccentric rotor 129 rotates, high-frequency vibration waves are generated. The high-frequency vibration waves can be transmitted to the connecting column 130 through the contact between the resonance tube 128 and the conduction tube 121. The vibration waves can be evenly transmitted to the sampling drill rod through the conduction between the connecting column 130 and the connecting head 114, so that the drill rod can perform high-frequency vibration while rotating at a high speed, so that the drilling and sampling work of the sampling drill rod can be more efficient. The addition is smooth, which is conducive to deep sampling. Before sampling, a signal can be sent through the reference positioning point 112 to transmit the spatial coordinate information of the current reference point. At this time, the infrared sensor 136 installed on the inner side of the mounting ring 135 can detect the verticality of the side wall of the connector 114, and the positioning sensor 137 at the bottom of the outer shell 124 can receive the spatial coordinate information of the reference positioning point 112, and can check the spatial coordinate system and calculate its own spatial coordinate information, so as to obtain the offset required to adjust the connector 114 to the vertical, so that people can quickly adjust the multi-terrain soil sampler 1 and the connector 114 to the horizontal and vertical, which can help to ensure the accuracy of subsequent fixed-point sampling. When sampling,The positioning sensor 137 at the bottom of the outer casing 124 can cooperate with the reference positioning point 112 to assist in calculating the depth of the connector 114 and the sampling drill rod, so as to realize the calibration and verification of the fixed-depth sampling, which is beneficial to further improve the accuracy of fixed-depth sampling. The signal generator installed at the bottom of the sampling drill rod can interact with the reference positioning point 112 during the sampling and drilling process to realize double verification. The signal amplifier can ensure that the sampling drill rod can still maintain the stability of the signal at a deeper sampling depth, which is beneficial to the fixed-depth sampling work. When sampling leveling and fixing the depth, the stepper motor can be started to drive the thread The rod 115 rotates, and the threaded rod 115 can drive the connecting block 138 and the ring frame 126 to descend as a whole and separate from the vibration frame 104. The heavier material of the outer protective shell 124 can use gravity to keep the outer protective shell 124 level, and at the same time can effectively reduce the influence of the internal vibration of the vibration frame 104 on the positioning sensor 137 and the infrared sensor 136. At the same time, the buffer block 123 installed outside the resonance cylinder 128 can shield and block the vibration wave of the resonance cylinder 128, further improving the stability of the vibration frame 104, and the magnetic coating inside the outer protective shell 124 can be connected with the mounting ring The magnetic rings 134 embedded on the periphery of 135 repel each other, so that the mounting ring 135 is not completely in contact with the outer shell 124, so that the precise depth and point sampling work can be less disturbed and more stable. When not positioned, the stepper motor can drive the threaded rod 115 to reverse, and the threaded rod 115 drives the connecting block 138 and the ring frame 126 to rise as a whole and embed into the opening 125, so as to protect the positioning components at this location. It is suitable for the transfer of the multi-terrain soil sampler 1 in complex terrain in the field. After multiple samplings, people can start the fixing frame 132 and the fixing frame 126 to move. The reduction motor on the second frame 116 can drive the guide wheel 120 to rotate through the reduction motor on the fixed frame 116, and the friction force can be used to drive the conductive cylinder 121 to rotate through the conductive cylinder 121. The reduction motor on the fixed frame 132 can drive the rotating frame 133 to rotate, and the friction force can be used to drive the conductive cylinder 121 to move up and down through the rotating frame 133, so that the contact point between the conductive cylinder 121 and the resonance cylinder 128 can be adjusted, so that the long-term single-point vibration of the conductive cylinder 121 can be effectively avoided, and the probability of damage to the conductive cylinder 121 is greatly reduced, which is beneficial to actual use.

10. A soil sampling method based on high-frequency sound waves, applied to a soil sampler based on high-frequency sound waves as claimed in any one of claims 1 to 9, characterized in that: The sampling steps include: S1. In actual use, people first drive the walking track wheel (107) through the motor inside the equipment compartment (101), so that the multi-terrain soil sampler (1) can move. When taking soil samples, people first lower the hydraulic support foot (108), and use the hydraulic support foot (108) to make the multi-terrain soil sampler (1) stop stably at the sampling point, so as to facilitate the sampling work; S2. After arriving at the sampling point, people start the multi-terrain soil sampler (1). At the beginning of sampling, the sampling drill rod is first installed at the bottom of the connector (114) by fixing bolts to complete the connection. Then, the vibration frame (104) is started. The vibration frame (104) is operated to make it rise and fall along the guide rail (102). The vibration frame (104) is lowered to drive the sampling drill rod installed at the bottom of the connector (114) to be lowered, so that the sampling drill rod is inserted into the soil to achieve sampling. The sampling depth of the sampling drill rod is adjusted by controlling the descending height of the vibration frame (104). S3. Before sampling, a signal is sent through the reference positioning point (112) to transmit the spatial coordinate information of the current reference point. At this time, the infrared sensor (136) installed on the inner side of the mounting ring (135) detects the verticality of the side wall of the connector (114). The positioning sensor (137) at the bottom of the outer protective shell (124) receives the spatial coordinate information of the reference positioning point (112), checks the spatial coordinate system, calculates its own spatial coordinate information, and thus obtains the offset required to adjust the connector (114) to the vertical position, thereby facilitating people to quickly adjust the multi-terrain soil sampler (1) and the connector (114) to the horizontal and vertical positions; S4. During the process of inserting the sampling drill rod for sampling, the servo motor inside the vibration frame (104) drives the eccentric rotor (129) to rotate synchronously. When the eccentric rotor (129) rotates, a high-frequency vibration wave is generated. The high-frequency vibration wave is transmitted to the connecting column (130) through the contact between the resonance tube (128) and the transmission tube (121). The vibration wave is evenly transmitted to the sampling drill rod through the transmission between the connecting column (130) and the connector (114). The drill rod vibrates at a high frequency while rotating at a high speed, so that the drilling and sampling work of the sampling drill rod is smoother, and the deep sampling work is completed. S5. During sampling, the positioning sensor (137) at the bottom of the outer casing (124) cooperates with the reference positioning point (112) to assist in calculating the depth of the connector (114) and the sampling drill rod, thereby achieving calibration and verification of fixed-depth sampling. During the sampling and drilling process, a signal generator installed at the bottom of the sampling drill rod interacts with the reference positioning point (112) to achieve double verification. A signal amplifier is used to ensure that the sampling drill rod still maintains a stable signal when sampling at a deeper depth. S6. After multiple samplings, people start the reduction motors on the fixed frame 1 (132) and the fixed frame 2 (116), and drive the guide wheel (120) to rotate through the reduction motor on the fixed frame 2 (116), and drive the conductive tube (121) to rotate by using the friction force, and drive the rotating frame (133) to rotate by using the reduction motor on the fixed frame 1 (132), and drive the conductive tube (121) to move up and down by using the friction force of the rotating frame (133), so as to adjust the contact point between the conductive tube (121) and the resonance tube (128), thereby effectively avoiding long-term single-point vibration of the conductive tube (121).
