It includes a base tube, a foot pedal fixedly fitted at the lower part of the base tube, and a soil-sampling drill bit fixedly installed at the lower end of the base tube. A conical spring is fitted onto both the base tube and the soil-sampling drill bit, and is also fixedly installed at the lower end of the foot pedal. A cleaning component is fixedly installed at the lower end of the conical spring and is movably fitted onto the soil-sampling drill bit. By fitting the conical spring onto the base tube and the soil-sampling drill bit, the sampler possesses a self-cleaning function. When the sampler completes sampling and is extracted from the ground, the conical spring can use its elasticity to drive the cleaning component to move adaptively along the outer wall of the soil-sampling drill bit.

Description

Technical Field

[0001] This utility model relates to the field of samplers, and in particular to a multifunctional sampler for geological exploration. Background Technology

[0002] In geological exploration, the geological exploration sampler is the core equipment for obtaining underground soil samples, and it is widely used in mineral resource exploration, engineering geological investigation, environmental geological survey, and other fields. Its main function is to penetrate deep into soil layers at different depths, collect and extract undisturbed soil samples through a sampling structure, providing a basic sample for subsequent analysis of soil composition, structure, physical and mechanical properties, directly affecting the accuracy of exploration data and the reliability of exploration conclusions. Currently, most geological exploration samplers on the market are mainly tubular in structure, equipped with a sampling drill bit, operating handle or foot pedal, and achieve soil sampling by rotating and pressing down. The structure is relatively simple and can meet basic sampling needs.

[0003] However, traditional geological exploration samplers have significant drawbacks in practical use. Because underground soil layers typically contain moisture, and the viscosity of soil layers varies considerably across different areas, a large amount of soil often adheres to the outer wall of the sampling drill bit when it is extracted from the ground. This adhered soil causes inconvenience for subsequent handling and operation, and also contaminates other components of the sampler. If not cleaned promptly, the dried soil will affect the accuracy of the sampler in subsequent uses and may even cause wear on the sampling drill bit. Utility Model Content

[0004] The main purpose of this invention is to provide a multifunctional sampler for geological exploration, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multifunctional sampler for geological exploration includes a base tube, a foot pedal fixedly fitted at the lower part of the base tube, a soil sampling drill bit fixedly installed at the lower end of the base tube, a conical spring fitted on the base tube and the soil sampling drill bit, the conical spring being fixedly installed at the lower end of the foot pedal, a cleaning component fixedly installed at the lower end of the conical spring, and the cleaning component being movably fitted on the soil sampling drill bit. The cleaning component consists of a base ring, contact rollers, a rotating shaft, a sleeve, a rubber ring, a cleaning rubber conical tube, and an annular cleaning cotton ring. There are four contact rollers symmetrically and rotatably installed inside the base ring. There are eight rotating shafts symmetrically and fixedly installed at both ends of the contact rollers, and the rotating shafts are also rotatably installed inside the base ring. The sleeve is fixedly fitted on the base ring. The rubber ring is inserted into the sleeve and located below the base ring, and the rubber ring is fixedly connected to the sleeve by bolts. The cleaning rubber conical tube is fixedly installed at the lower end of the rubber ring, and the annular cleaning cotton ring is installed inside the rubber ring.

[0006] Preferably, a handle is fixedly installed at the upper end of the base pipe, and a bulldozing component is movably installed inside the base pipe, the handle, and the soil-boring drill bit.

[0007] Preferably, the base ring, sleeve, rubber ring, cleaning rubber cone tube, and annular cleaning cotton ring on the cleaning component are all annular structures, and the base ring, cleaning rubber cone tube, and annular cleaning cotton ring are all movably sleeved on the soil sampling drill bit, and the cleaning rubber cone tube and annular cleaning cotton ring are in contact with the outer wall of the soil sampling drill bit.

[0008] Preferably, four storage slots are symmetrically opened on the inner wall of the base ring on the cleaning component, and two shaft holes are symmetrically opened on the inner wall of the storage slots. The contact roller is rotatably installed in the storage slots and contacts the outer wall of the soil sampling drill bit. The rotating shaft is rotatably installed in the shaft hole.

[0009] Preferably, the sleeve has two symmetrical first screw holes, and the outer wall of the rubber ring has two symmetrical second screw holes. Bolts for fixing the sleeve and the rubber ring are installed in the first and second screw holes. The cleaning rubber cone tube is located at the lower end of the sleeve, and the base ring is fixedly connected to the lower end of the conical spring.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By installing conical springs on the base pipe and the soil sampling drill bit, and installing a cleaning assembly on the drill bit consisting of a base ring, contact roller, rotating shaft, sleeve, rubber ring, cleaning rubber conical tube, and annular cleaning cotton ring, the sampler acquires a self-cleaning function. When the sampler completes sampling and is extracted from the ground, the conical springs use their elasticity to drive the cleaning assembly to move adaptively along the outer wall of the drill bit. The cleaning rubber conical tube first scrapes off a large amount of soil adhering to the outer wall of the drill bit, and then the annular cleaning cotton ring wipes off the remaining fine soil particles, achieving a comprehensive cleaning of the outer wall of the drill bit. This avoids inconvenience in subsequent handling operations caused by soil adhesion and contamination of other parts of the sampler. At the same time, the presence of the contact roller allows the cleaning assembly to roll in contact with the outer wall of the drill bit during movement, reducing the frictional resistance between the cleaning assembly and the drill bit, making the movement of the cleaning assembly smoother, reducing component wear, and extending service life.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] Please see Figure 1 - Figure 4As shown, a multifunctional sampler for geological exploration includes a base pipe 1, a foot pedal 2 fixedly fitted on the lower part of the base pipe 1, a soil sampling drill bit 3 fixedly installed at the lower end of the base pipe 1, a conical spring 4 fitted on the base pipe 1 and the soil sampling drill bit 3, the conical spring 4 being fixedly installed at the lower end of the foot pedal 2, and a cleaning component 5 fixedly installed at the lower end of the conical spring 4. The cleaning component 5 is movably fitted on the soil sampling drill bit 3. The cleaning component 5 consists of a base ring 8, a contact roller 11, a rotating shaft 12, a sleeve 13, a rubber ring 15, and a cleaning rubber conical tube. The system consists of a 17 and an annular cleaning cotton ring 18. Four contact rollers 11 are symmetrically and rotatably mounted inside the base ring 8. Eight rotating shafts 12 are symmetrically and fixedly mounted in pairs at both ends of the contact rollers 11. The rotating shafts 12 are also rotatably mounted inside the base ring 8. A sleeve 13 is fixedly fitted onto the base ring 8. A rubber ring 15 is inserted into the sleeve 13 and located below the base ring 8, and the rubber ring 15 is fixedly connected to the sleeve 13 by bolts. A cleaning rubber cone tube 17 is fixedly installed at the lower end of the rubber ring 15. The annular cleaning cotton ring 18 is installed on the rubber ring 15. Inside the sampler, a conical spring 4 is fitted onto the base pipe 1 and the soil sampling drill bit 3. A cleaning assembly 5, consisting of a base ring 8, contact roller 11, rotating shaft 12, sleeve 13, rubber ring 15, cleaning rubber conical tube 17, and annular cleaning cotton ring 18, is fitted onto the soil sampling drill bit 3. This gives the sampler a self-cleaning function. When the sampler completes sampling and is extracted from the ground, the conical spring 4 can use its elasticity to drive the cleaning assembly 5 to move adaptively along the outer wall of the soil sampling drill bit 3. The cleaning rubber conical tube 17 first cleans the outer wall of the soil sampling drill bit 3. The large amount of attached soil is initially scraped off, and then the annular cleaning cotton ring 18 can wipe the remaining fine soil particles a second time, achieving a comprehensive cleaning of the outer wall of the soil sampling drill bit 3, avoiding the inconvenience of subsequent handling operations caused by soil adhesion and the contamination of other parts of the sampler; at the same time, the presence of the contact roller 11 allows it to roll into contact with the outer wall of the soil sampling drill bit 3 during the movement of the cleaning component 5, reducing the frictional resistance between the cleaning component 5 and the soil sampling drill bit 3, making the movement of the cleaning component 5 smoother, reducing component wear, and extending service life.

[0015] Furthermore, a handle 6 is fixedly installed at the upper end of the base pipe 1. A bulldozing component 7 is movably installed inside the base pipe 1, handle 6, and soil-boring drill bit 3. The base ring 8, sleeve 13, rubber ring 15, cleaning rubber cone tube 17, and annular cleaning cotton ring 18 on the cleaning component 5 are all annular structures. The base ring 8, cleaning rubber cone tube 17, and annular cleaning cotton ring 18 are all movably fitted onto the soil-boring drill bit 3, and the cleaning rubber cone tube 17 and annular cleaning cotton ring 18 are in contact with the outer wall of the soil-boring drill bit 3. Four symmetrically arranged storage grooves 9 are formed on the inner wall of the base ring 8 on the cleaning component 5. Two symmetrically arranged shaft holes 10 are formed on the inner wall of the storage grooves 9. The contact roller 11 is rotatably installed in the receiving groove 9, and the contact roller 11 contacts the outer wall of the soil sampling drill bit 3. The rotating shaft 12 is rotatably installed in the shaft hole 10. Two first screw holes 14 are symmetrically opened on the sleeve 13, and two second screw holes 16 are symmetrically opened on the outer wall of the rubber ring 15. Bolts for fixing the sleeve 13 and the rubber ring 15 are installed in the first screw holes 14 and the second screw holes 16. The cleaning rubber cone tube 17 is located at the lower end of the sleeve 13. The base ring 8 is fixedly connected to the lower end of the conical spring 4. When using this multi-functional sampler for geological exploration, the operator first holds the handle 6 at the upper end of the base tube 1 with both hands and aligns the soil sampling drill bit 3 with the ground to be sampled. Position the sampler, then step on the foot pedal 2 at the bottom of the base pipe 1 to allow the soil sampling drill bit 3 to gradually drill into the underground soil under pressure. During this process, the cleaning component 5 fitted on the soil sampling drill bit 3 will be blocked by the ground. As the soil sampling drill bit 3 descends, the cleaning component 5 will compress the conical spring 4. When the soil sampling drill bit 3 has drilled to the preset sampling depth, stop stepping on the foot pedal 2, then pull the handle 6 upwards with both hands to pull the entire sampler out of the ground. During the extraction process, the compressed conical spring 4 will gradually regain its elasticity and drive the cleaning component 5 to move downwards along the outer wall of the soil sampling drill bit 3. At this time, the cleaning component 5 will be cleaned at the lower end of the rubber ring 15. The rubber cone tube 17 first scrapes away a large amount of soil adhering to the outer wall of the soil sampling drill bit 3. At the same time, the annular cleaning cotton ring 18 inside the rubber ring 15 will follow up to wipe away the fine soil particles remaining on the outer wall of the soil sampling drill bit 3. When the cleaning component 5 moves along the soil sampling drill bit 3, the contact roller 11 will roll and contact the outer wall of the soil sampling drill bit 3 to reduce the frictional resistance when the cleaning component 5 moves. After the sampler is completely pulled out of the ground, if it is necessary to take out the soil sample in the soil sampling drill bit 3, the base tube 1, handle 6 and the soil pushing component 7 in the soil sampling drill bit 3 can be pushed to push out the soil sample in the soil sampling drill bit 3, thus completing one sampling operation.

[0016] After using the cleaning component 5, if dirt adheres to its outer wall, it can be cleaned immediately by wiping with a damp cloth or rinsing with a high-pressure water gun. During the cleaning process, avoid direct water flow impacting the connection between the conical spring 4 and the base ring 8 to prevent affecting the connection stability between the components. After a period of use, if the cleaning rubber conical tube 17 is found to be worn or deformed, or if the annular cleaning cotton ring 18 absorbs too much dirt, resulting in a decrease in cleaning effect, first unscrew the bolts connecting the sleeve 13 and the rubber ring 15, remove the rubber ring 15 from the sleeve 13, and then clean the cleaning rubber conical tube 17 and the annular cleaning cotton ring 18 respectively. Disassemble ring 18. For cleaning rubber cone tube 17, use a soft brush with clean water to wash away residual dirt on the surface. If the wear is severe, replace it with a new cleaning rubber cone tube 17 and rubber ring 15. For annular cleaning cotton ring 18, soak it in clean water and rub it to remove the dirt and impurities adsorbed inside. After cleaning, let it dry. Then, install the annular cleaning cotton ring 18 back into the inside of rubber ring 15 in the reverse order of disassembly. Finally, insert rubber ring 15 back into sleeve 13 and fix it with bolts to ensure that cleaning component 5 restores good cleaning performance to meet the needs of subsequent sampling.

[0017] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
