Description

Technical Field

[0001] The invention relates to the technical field of soil sampling, in particular to an anti-clogging soft soil sampler and a cleaning method thereof. Background Art

[0002] Soft soil sampler is an engineering tool used to collect soil samples from soft soil layers, which is widely used in geotechnical engineering investigation, environmental engineering and geological research. It can obtain undisturbed soil samples that can reflect the physical, chemical and mechanical properties of the soil layer for laboratory testing and analysis. However, the soft soil sampler of the prior art has some significant deficiencies in practical application, especially in the anti-blocking and cleaning of the soft soil sampler.

[0003] First, in the actual application of traditional soft soil samplers, there may be varying degrees of disturbance due to the viscosity, unevenness and moisture content of the soft soil, which may lead to blockage of the soft soil sampler. For example, the existing open thin-walled soil samplers, medium-thick walled soft soil samplers, etc., when taking soil samples, these samplers may cause the soil samples to stick inside the sampler and become blocked due to the high moisture content and viscosity of the soft soil, as well as the different sizes of particles contained in the soft soil layer. In particular, for newly deposited clay soil, due to its poor physical and mechanical properties, low strength, medium to high sensitivity and thixotropy, it is very easy to be disturbed during the soil sampling process, which not only affects the test results, but also causes blockage to the sampler, greatly reducing work efficiency.

[0004] Secondly, the existing soft soil samplers have some design problems and insufficient equipment maintenance. If the design of the sampler is not suitable for a specific type of soft soil, such as the wall thickness is not thin enough or the edge is not smooth enough, it may cause soil samples to accumulate in the sampler; and because it is not cleaned and maintained in time after use, soil sample residues accumulate, increasing the risk of blockage. Continuous use will inevitably cause blockage of the soft soil sampler, affecting the continuation of subsequent work.

[0005] Finally, when using a soft soil sampler for sampling, improper operation may cause significant changes in soil strength and deformation characteristics, and may also cause soil moisture loss or structural damage, resulting in soft soil clogging in the sampler. Improper operation may also pollute the environment and pose risks to the health and safety of on-site operators. Of course, soil may also be blocked in the sampler because the speed of inserting or removing the sampler is not uniform or the sampler is not correctly inserted vertically into the soil during the sampling process.

[0006] Therefore, in order to solve the problems existing in the above background technology, those skilled in the art have developed an anti-clogging soft soil sampler with a cleaning function in which an anti-clogging mechanism and a soil sampling mechanism work together. The present invention, through a special design, not only avoids the surface soil above the target depth from causing great disturbance to the target soil and making soil sampling difficult, but also improves the efficiency and quality of sampling and sample preparation.

[0025] In addition, the present invention also provides a cleaning method for an anti-clogging soft soil sampler, comprising the following steps:

[0026] S1. After the sample enters the sample tube, the water delivery pipe 3 is connected to the water delivery hose through a magnetic connector;

[0027] S2, the water pump starts to work, and the water flows from the transfer tank into the water pipe 2, and then into the water hose;

[0028] S3. As water flows continuously into the drill pipe cavity, the downward pressure of the water flow on the bulldozer ball is greater than the tension of the hoisting spring, and the bulldozer ball pushes the soil downward;

[0029] S4. After the sample soil is discharged, the thrust of the soil on the lower piece of the bulldozer ball disappears, the upper and lower pieces of the bulldozer ball separate to create a gap, and the bulldozer ball is pulled up at the same time;

[0030] S5, continue to input water flow, the water flow flows into the sample tube from the gap of the bulldozer ball piece, and washes the sample tube and the bulldozer ball piece;

[0031] S6. After flushing is completed, water supply is stopped and the bulldozer ball is pulled back to its original position.

[0032] Working principle: When taking soil, the hydraulic press starts, driving the power plate to move downward. The power plate is stably connected to the output end of the hydraulic press to ensure effective power transmission. The power plate pushes the motor and the drill rod connected to the motor to move downward together. When the drill rod gradually penetrates into the soil, the motor starts to work, driving the groove on the outer wall of the drill rod to rotate through the belt, so that the drill rod rotates. At the same time, the drill bit breaks the soil under the joint action of the drill rod and the motor. Since the bottom end of the drill bit is designed as a ring-shaped sawtooth and the shape of the sawtooth is designed as a trapezoid, this design mechanism is easier to break the soil. At the same time, one end of the drill rod gradually penetrates the shockproof plate and penetrates into the position where soil needs to be taken. The shockproof plate can reduce the vibration generated when the drill rod is working and ensure the stable operation of the mechanism. During the rotation of the drill rod, the soil is cut and brought into the inside of the drill rod. When the soil enters the sample tube connected to the drill rod through one end of the drill rod, the middle layer of the soil retaining sheet is made of polyethylene (PE), so the soil retaining sheet automatically opens under the action of soil squeezing force to allow the soil to flow into the sample tube. After entering the sample tube, the soil first contacts the hanging spring and the bulldozer ball. After the soil is taken, the hydraulic press retracts the power plate and the drill rod rises. When the soil enters the sample tube, the bulldozer ball can push the soil downward under the action of the water flow to discharge the soil sample and prevent soil blockage. At the same time, one side of the outer wall of the sample tube is connected to a water pipe three, which can be used for water injection to help the soil flow smoothly and clean the soil sample adhering to the sample tube and the bulldozer ball. The groove on the outer wall of the drill rod is driven by a belt to rotate, so that the drill rod rotates, and the soil discharge valve on the sample tube automatically opens under the action of the rotating centrifugal force. As the drill rod continues to move downward, the soil above the sampling depth continuously enters the sample tube and is discharged from the soil discharge valve to the soil collection cover until the sample tube is filled with soil at the specified depth. After the sampling is completed, as the drill rod rises, the soil extrusion force disappears and the soil protection sheet automatically closes to protect the sample soil from being lost. At the same time, the soil in the soil collection cover can be sampled in layers. The groove on the outer wall of the drill rod is driven by a belt to rotate, so that the drill rod rotates, and the soil discharge valve on the sample tube automatically opens under the action of the rotating centrifugal force. As the drill rod continues to move downward, the soil above the sampling depth continuously enters the sample tube and is discharged from the soil discharge valve to the soil collection cover until the sample tube is filled with soil at the specified depth. After the sampling is completed, as the drill rod rises, the soil extrusion force disappears and the soil protection sheet automatically closes to protect the sample soil from being lost. At the same time, the soil in the soil collection cover can be sampled in layers. Specifically, the water tank is used to store liquid, and the liquid in the water tank on one side is transported to the liquid transfer tank through water pipe 1. The liquid transfer tank moves with the power board, and when liquid supply is needed, the water pump is started to pump the liquid in the liquid transfer tank through water pipe 2. The pumped liquid is transported through a water hose, and the other end of the water hose is quickly connected to the water pipe 3 through a magnetic connector.The magnetic connector uses magnetic force to fix and absorb to ensure the stability and sealing of the connection, so that the liquid can flow smoothly from the water hose into the water pipe three. At the same time, the liquid in the water tank on the other side is transported to the nozzle through the soft water pipe. The nozzle can be used to clean the equipment or other related operations. Such a liquid supply mechanism design can flexibly provide the required liquid for the soil excavation operation to ensure the smooth progress of the operation, and the magnetic connector can be used to quickly connect and disassemble, which is convenient for operation. When the equipment is driving on an uneven road or is impacted, the tire is first vibrated and transmitted to the transmission rod. The transmission rod transmits the vibration energy to the transmission frame, and the transmission mechanism inside the transmission frame converts and consumes the vibration energy. At the same time, the spring in the shock absorber assembly also participates in the shock absorption process, further absorbing and consuming the vibration energy. Finally, through the synergistic effect of the drive mechanism and the shock absorber assembly, the vibration energy is reduced to an acceptable range to protect the internal structure of the equipment. When the operator stands in front of the operating table, he can first see the operating table fixedly connected to one side of the outer wall of the external shell. In the center of the operating table is a conspicuous display screen, through which the operator can understand the operating status, various parameters and related information of the equipment in real time. At the lower end of the console, operating levers and operating buttons are symmetrically arranged. The operator can control the moving direction and speed of the equipment through the operating lever, and execute various specific operating instructions, such as start, stop, speed regulation, etc. through the operating buttons. In the upper right corner of the console, the emergency brake switch is also fixedly connected. In case of emergencies, the operator can quickly press the emergency brake switch to stop the equipment immediately to ensure safety. When operation is required, the operator flexibly uses the operating lever, operating button and emergency brake switch according to specific needs, and at the same time grasps the operation status of the equipment at any time through the display screen, thereby realizing precise control and operation of the entire equipment.

[0033] The present invention provides an anti-clogging soft soil sampler and a cleaning method thereof, which has the following beneficial effects:

[0034] 1. The present invention can complete the collection of deep soil through the joint action of the anti-clogging mechanism and the soil taking mechanism. Under the joint action of the bulldozer in the anti-clogging mechanism and the water flow in the water pipe, the soil sample can be easily discharged and the residual sample can be cleaned out, solving the problem of easy blockage in soft soil sampling.

[0035] 2. The present invention provides a soil discharge valve on the sample tube under the action of the soil taking mechanism. In the process of the soil taking mechanism continuously going deep into the soil layer, the soil discharge valve is automatically opened by the centrifugal force through the rotational force of the belt transmission motor. As the soil continues to enter, the surface soil above the target depth is discharged from the valve, achieving the effect of not sampling the surface soil above the target depth, and solving the problem that the surface soil above the target depth greatly disturbs the target soil sample.

[0036] 3. The present invention designs the drill bit part as a modular component under the action of the soil taking mechanism, which is convenient for disassembly and replacement. At the same time, the bottom of the drill bit is designed to be annularly toothed, and the tooth head part is designed to be trapezoidal. This design can better break the surface soil above the target depth and solve the problem of difficulty in soil sampling. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Example:

[0048] Please see attached Figure 1 - Attachment Figure 8 , an embodiment of the present invention provides an anti-clogging soft soil sampler, comprising:

[0049] The external housing 1, as the basic component of the whole device, is used to carry and assemble the anti-blocking mechanism and its subordinate structural components, and is fixed to the upper wall of the driving mechanism;

[0050] A hydraulic press 2, which is fixedly connected to one side of the outer wall of the external housing 1, and an end of a drill rod 5 is provided at its output end;

[0051] The drill bit 3 is arranged at the other end of the drill rod 5 and is used to break the soil and penetrate into the soil layer;

[0052] An anti-clogging mechanism, which is arranged at one end of the inner part of the external shell 1 and is used to push and clean the soft soil sample;

[0053] An operating mechanism, which is arranged on the side wall of the external shell 1, is used to control each processing mechanism and its subordinate structural parts, and is fixed on the side wall of the external shell 1;

[0054] A liquid supply mechanism, which is arranged on both sides of the external housing 1, and is used to clean the anti-clogging mechanism and cool the earth drilling equipment;

[0055] A driving mechanism, which is arranged at the bottom end of the external housing 1 and provides the entire device with forward momentum;

[0056] The soil-extracting mechanism is arranged inside the external shell 1 and is used to provide downward pressure power for the soil-extracting device.

[0057] The anti-clogging mechanism includes a sample tube 4, which is connected to one end of a drill pipe 5. A hanging spring 6 is arranged inside the sample tube 4. One end of the hanging spring 6 is fixedly connected to one side of the inner wall of the drill pipe 5. A bulldozer ball piece 7 is arranged at the other end of the hanging spring 6. The bulldozer ball piece 7 is divided into an upper and a lower piece. A connecting rod 8 is slidably connected between the two bulldozer ball pieces 7. The upper bulldozer ball piece 7 is magnetically connected to one end of the outer wall of the hanging spring 6. One side of the outer wall of the sample tube 4 is connected to one end of a water pipe 39. The top of the sample tube 4 is rotatably connected to a soil discharge valve 10. The lower end of the sample tube 4 is fixedly connected to a soil collecting cover 11 and is threadedly connected to a soil retaining piece 12. The soil discharge valve 10 is rotatably connected to the top of the sample tube 4. The soil retaining piece 12 is divided into three layers, upper, middle and lower. The three layers are connected by mortise and tenon joints.

[0058] The soil-taking mechanism includes a power plate 13, which is fixedly connected to the output end of the hydraulic press 2. A motor 14 is fixedly connected to one side of the outer wall of the power plate 13. A groove is provided on the outer wall of the drill rod 5. The output end of the motor 14 is connected to the groove through a belt. A shockproof plate 15 is fixedly connected to one end of the inner wall of the external shell 1, and one end of the drill rod 5 passes through the shockproof plate 15.

[0059] Specifically, when performing soil extraction operation, the hydraulic press 2 is started, driving the power plate 13 to move downward. The power plate 13 is stably connected to the output end of the hydraulic press 2 to ensure effective power transmission. The power plate 13 drives the motor 14 and the drill rod 5 connected to the motor 14 to move downward together. When the drill rod 5 gradually penetrates into the soil, the motor 14 starts to work, and drives the groove on the outer wall of the drill rod 5 to rotate through the belt, so that the drill rod 5 rotates. At the same time, the drill bit 3 breaks the soil under the joint action of the drill rod 5 and the motor 14. Since the bottom end of the drill bit 3 is designed as an annular sawtooth and the shape of the sawtooth is designed as a trapezoid, this design mechanism is easier to break the soil. At the same time, one end of the drill rod 5 gradually penetrates the shockproof plate 15 and penetrates into the position where soil needs to be extracted. The shockproof plate 15 can reduce the vibration generated when the drill rod 5 is working and ensure the stable operation of the mechanism. During the rotation process, the drill rod 5 cuts the soil and brings it into the interior of the drill rod 5. When the soil enters the sample tube 4 connected to the drill rod 5 through one end of the drill rod 5, since the middle layer of the soil retaining sheet 12 is made of polyethylene (PE), the soil retaining sheet 12 automatically opens under the action of the soil squeezing force to allow the soil to flow into the sample tube 4. After entering the sample tube 4, the soil first contacts the hanging spring 6 and the bulldozer ball 7. After the soil is taken, the hydraulic press 2 retracts the power plate 13, and the drill rod 5 rises accordingly. When the soil enters the sample tube 4, the bulldozer ball 7 can push the soil downward under the action of the water flow, discharge the soil sample, and prevent the soil from being blocked. At the same time, one side of the outer wall of the sample tube 4 is connected to a water pipe 3 9, which can be used for water injection, helping the soil to flow smoothly while cleaning the soil sample adhering to the sample tube 4 and the bulldozer ball 7.

[0060] Specifically, the groove on the outer wall of the drill rod 5 is driven by a belt to rotate, so that the drill rod 5 rotates, and at the same time, the soil discharge valve 10 on the sample tube 4 is automatically opened under the action of the rotating centrifugal force. As the drill rod 5 continues to move downward, the soil above the sampling depth continuously enters the sample tube 4 and is discharged from the soil discharge valve 10 into the soil collecting cover 11 until the sample tube 4 is filled with soil at a specified depth. After the sampling is completed, as the drill rod 5 rises, the soil squeezing force disappears and the soil retaining sheet 12 automatically closes to protect the sample soil from being lost. At the same time, the soil in the soil collecting cover 11 can be sampled in layers.

[0061] The liquid supply mechanism includes a water tank 16, and the two water tanks 16 are fixedly connected to both sides of the outer wall of the upper end of the external shell 1. The output end of the water tank 16 on one side is connected to one end of a water pipe 17, and the other end of the water pipe 17 is connected to the upper wall of a liquid transfer box 18. The liquid transfer box 18 is fixedly connected to one side of the outer wall of the power plate 13. A water pump 19 is fixedly connected inside the liquid transfer box 18, and the output end of the water pump 19 is connected to one end of a water pipe 20, and the other end of the water pipe 20 is connected to one end of a water hose 21. The other end of the water hose 21 is connected to one end of a water pipe 3 9 through a magnetic connector 22. The water tank 16 on the other side is connected to one end of a soft water pipe 23, and the other end of the soft water pipe 23 is connected to a nozzle 24.

[0062] Specifically, the water tank 16 is used to store liquid, and the liquid in the water tank 16 on one side is transported to the liquid transfer tank 18 through the water pipe 17. The liquid transfer tank 18 moves with the power plate 13. When liquid supply is needed, the water pump 19 is started to extract the liquid in the liquid transfer tank 18 through the water pipe 20. The extracted liquid is transported through the water hose 21, and the other end of the water hose 21 is quickly connected to the water pipe 3 9 through the magnetic connector 22. The magnetic connector 22 is fixed by magnetic adsorption to ensure the stability and sealing of the connection, so that the liquid can flow smoothly from the water hose 21 to the water pipe 3 9. At the same time, the liquid in the water tank 16 on the other side is transported to the nozzle 24 through the soft water pipe 23. The nozzle 24 can be used for cleaning the equipment or other related operations.
