Description

TECHNICAL FIELD

[0001] The utility model relates to soil sampling technology field, concretely relates to a foundation soil sampling device. BACKGROUND

[0002] The foundation soil sampling device, commonly known as soil sampling equipment or soil sampler, is a scientific instrument specially used for collecting foundation soil samples. This kind of device is widely used in the fields of earth science, environmental science and technology, and resource science and technology, and has important significance for the research, analysis and monitoring of foundation soil.

[0003] Through the search, the patent with the patent publication number CN202122764394.6 discloses a soil detection shockproof sampling device for water conservancy engineering construction. Although the device can make the soil sample enter into the communication pipe 801 through the conduit 7 under the action of the drill bit 6 when the motor 5 works, the device cannot process the residual soil sample in the conduit when in use. The residual soil sample in the conduit may mix with the new soil sample, resulting in the pollution of the collected soil sample and affecting the accuracy of soil sample analysis. Due to the pollution of the soil sample, the deviation may occur in the subsequent analysis of the physical and chemical properties of the soil sample, thereby affecting the accurate judgment of the foundation soil. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a foundation soil sampling device, which solves the problems proposed in the background art.

[0005] The technical problems solved by the utility model are as follows:

[0006] A foundation soil sampling device, comprising an upper connecting pipe, a motor is installed at the top end of the upper connecting pipe, a screw auger is installed in the output end of the motor in the upper connecting pipe,

[0007] A fixing plate is arranged at the connection between the upper connecting pipe and the motor, the upper connecting pipe is installed and fixed through the fixing plate, a tee pipe is connected to the bottom end of the upper connecting pipe, one end of the tee pipe away from the upper connecting pipe is connected to a lower connecting pipe, and one end of the tee pipe away from the upper connecting pipe and the lower connecting pipe is connected to a discharge pipe.

[0008] An inner pipe is inserted into the tee pipe and the lower connecting pipe, an upper edge plate is arranged on the inner pipe, the upper edge plate is located between the upper connecting pipe and the tee pipe, the upper edge plate is clamped and fixed by the upper connecting pipe and the tee pipe, thereby fixing the inner pipe in the tee pipe and the lower connecting pipe, and a discharge port is formed in the inner pipe, and the position and size of the discharge port correspond to the discharge pipe.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, the tee pipe is connected with the upper connecting pipe, the lower connecting pipe and the discharge pipe through the locking and fixing of the hoop.

[0011] The beneficial effects of the above further scheme are:

[0012] The use of the hoop for connection greatly simplifies the installation process compared to traditional welding or flange connection methods. The hoop is usually easy to assemble and disassemble and adjust, without the need for complex power cables, cutting tools, welding machines and other equipment, reducing the construction difficulty and time cost. The hoop cooperates with the sealing ring to form a tight and reliable connection, effectively preventing fluid (such as soil samples) leakage. This sealing structure not only ensures the accuracy of the sampling process, but also avoids environmental pollution problems caused by leakage. Since the hoop connection has the characteristics of easy disassembly, it can be quickly operated when maintenance or replacement of parts is required. This not only reduces maintenance costs, but also improves the maintainability and flexibility of the equipment.

[0013] Further, the inner pipe is composed of two parts, and a limiting rib is arranged on the inner pipe, the inner pipe is inserted into the insertion slot in the tee pipe and the lower connecting pipe through the limiting rib, and the position of the inner pipe is limited.

[0014] The beneficial effects of the above further scheme are:

[0015] Through the insertion mode of the limiting rib and the insertion slot, the connection between the inner pipe and the tee pipe and the lower connecting pipe becomes more stable. This design effectively prevents the inner pipe from shaking or shifting during sampling, ensuring the accuracy and stability of sampling. The inner pipe is designed to be detachable and is inserted into the insertion slot through the limiting rib, making the installation and disassembly process simple and fast. This not only facilitates the daily maintenance and cleaning of the equipment, but also improves the sampling efficiency. The precise design of the limiting rib ensures that the inner pipe can accurately align with the insertion slot when inserted into the tee pipe and the lower connecting pipe, thereby avoiding sampling errors caused by positional deviation. The insertion mode of the limiting rib and the insertion slot not only provides a stable connection, but also enhances the frictional resistance between the inner pipe and the tee pipe and the lower connecting pipe. This design helps to reduce wear and looseness caused by long-term use, thereby prolonging the service life of the equipment. The design of the inner pipe composed of two parts makes it convenient to replace or upgrade the inner pipe components when needed. This flexibility not only improves the versatility of the equipment, but also facilitates users to customize and modify according to actual needs. Since the inner pipe can be easily disassembled and cleaned, it avoids sampling errors and clogging problems caused by soil residues. This not only improves the sampling efficiency, but also ensures the accuracy and representativeness of the soil samples.

[0016] Further, sealing rings are arranged between the tee pipe and the lower connecting pipe and the discharge pipe.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The sealing ring can fill the tiny gap at the pipe connection, effectively preventing fluid (such as gas, liquid or soil sample) from leaking. This ensures the accuracy of the sampling process and avoids environmental pollution problems caused by leakage. The sealing ring is usually made of elastic materials such as rubber or silicone, which has good elasticity and sealing performance. By setting a sealing ring at the pipe connection, the sealing performance of the connection can be greatly improved to ensure that the fluid does not leak from the connection. The sealing ring not only provides sealing function, but also increases the friction resistance of the pipe connection, thereby improving the stability of the connection. This helps to prevent the pipe from loosening or falling off due to excessive force during the sampling process. By setting a sealing ring, the connection between the tee pipe and the lower connecting pipe and the discharge pipe can be more tightly and reliably connected, improving the stability of the entire sampling device.

[0019] Further, the top end of the inner pipe is provided with a stop block, and the output end of the motor penetrates the stop block and is connected with the auger.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The design of the stop block provides a stable support point for the inner pipe, enhancing the structural stability of the entire sampling device. This helps to prevent deformation or damage of the inner pipe due to excessive force during the sampling process. The output end of the motor penetrates the stop block and is connected with the auger, ensuring a firm and reliable connection between the motor and the auger. During the sampling process, the motor can stably drive the auger to rotate, thereby achieving efficient collection of soil samples. The stop block not only provides support for the inner pipe, but also protects the motor and the auger. During the sampling process, the stop block can withstand part of the impact force from the soil sample, thereby reducing the burden on the motor and the auger and prolonging their service life.

[0022] The utility model provides a kind of ground soil sampling device. It has the following beneficial effects:

[0023] The device forms a complete sampling system through the combination design of upper connecting pipe, tee pipe, lower connecting pipe and discharge pipe. This design not only makes the sampling process more smooth, but also tightly connects each component, reducing the leakage problem during sampling.

[0024] The motor drives the auger to rotate in the upper connecting pipe, and the soil sample is pushed into the inner pipe by the helical blade of the auger. This mechanism ensures that the soil sample can be effectively collected and reduces the complexity of manual operation.

[0025] The inner tube is designed to be detachable, and is inserted into the insertion slot in the tee pipe and the lower connecting pipe through the limiting ribs, so that the installation and disassembly of the inner tube become simple and fast. This not only facilitates the cleaning of the inner tube, avoids the sampling error caused by soil residues, but also prolongs the service life of the device.

[0026] Since the inner tube can be easily disassembled and cleaned, the sampling period can be greatly shortened in actual operation, and the sampling efficiency is improved. At the same time, the position and size of the discharge port correspond to the discharge pipe, which ensures that the soil sample can be accurately discharged, further improving the accuracy and efficiency of sampling.

[0027] The tee pipe, the upper connecting pipe, the lower connecting pipe and the discharge pipe are all provided with sealing rings and are locked and fixed by the hoop. This design ensures the stable and reliable connection between the components, and avoids the problems of loosening and leakage during sampling. BRIEF DESCRIPTION OF DRAWINGS

Compared with traditional welding or flange connection method, the use of hoop 3 connection technology significantly simplifies the installation process. Hoop 3 is easy to assemble, disassemble and adjust, without the need for complex power facilities, cutting tools and welding equipment, effectively reducing construction complexity and time cost. Combined with the application of sealing ring, hoop 3 connection can form a tight and reliable sealing structure, effectively preventing the leakage of fluid (such as soil sample). This sealing design not only ensures the accuracy of sampling process, but also avoids the risk of environmental pollution caused by leakage. The detachability of hoop 3 connection makes maintenance or replacement of parts quick and efficient, further reducing maintenance cost and improving maintainability and flexibility of the equipment.

[0040] Embodiment two

[0041] For the disassembly and cleaning of the inner tube 8, as shown in the example Figures 1 to 4 The application also includes: the tee pipe 2 and the lower connecting pipe 4 are inserted with the inner tube 8, the inner tube 8 is composed of two parts, and the inner tube 8 is provided with a limiting rib 803, the inner tube 8 is inserted with the slot in the tee pipe 2 and the lower connecting pipe 4 through the limiting rib 803, and the position of the inner tube 8 is limited, thereby facilitating the installation and disassembly of the inner tube 8, so as to facilitate the cleaning of the inner tube 8, thereby improving the sampling efficiency. The precise insertion mode of the limiting rib 803 and the slot significantly improves the connection strength between the inner tube 8 and the tee pipe 2 and the lower connecting pipe 4. This design effectively suppresses the shaking or displacement of the inner tube 8 during sampling, ensuring the accuracy and stability of sampling. The inner tube 8 adopts a detachable design and is quickly inserted with the slot through the limiting rib 803, simplifying the installation and disassembly process and improving the daily maintenance convenience and sampling efficiency of the equipment. The precise design of the limiting rib 803 ensures that the inner tube 8 can be accurately aligned with the slot when inserted into the tee pipe 2 and the lower connecting pipe 4, avoiding sampling errors caused by positional deviation. The insertion mode of the limiting rib 803 and the slot not only enhances the stability of the connection, but also improves the frictional resistance between the inner tube 8 and the tee pipe 2 and the lower connecting pipe 4, which helps to reduce wear and looseness during long-term use and prolong the service life of the equipment. The two-part design of the inner tube 8 facilitates the replacement or upgrading of the inner tube 8 components, improving the versatility of the equipment and the convenience of user customization. The easy disassembly of the inner tube 8 avoids sampling errors and clogging problems caused by soil residues, improving the sampling efficiency and the accuracy and representativeness of soil samples. The top end of the inner tube 8 is provided with a stop block 801, and the output end of the motor 7 penetrates the stop block 801 and is connected with the auger transmission. The design of the stop block 801 provides a stable support structure for the inner tube 8, enhancing the structural stability of the entire sampling device. This helps to prevent deformation or damage of the inner tube 8 due to excessive force during sampling. The output end of the motor 7 is connected with the auger through the penetration of the stop block 801, which ensures the firm and reliable connection between the motor 7 and the auger. During sampling, the motor 7 can stably drive the auger to rotate, achieving efficient collection of soil samples. The stop block 801 not only provides support for the inner tube 8, but also protects the motor 7 and the auger. During sampling, the stop block 801 can withstand part of the impact force from the soil sample, thereby reducing the load on the motor 7 and the auger and prolonging their service life. The inner tube 8 is provided with an upper edge plate 804, which is located between the upper connecting pipe 1 and the tee pipe 2. The upper edge plate 804 is clamped and fixed by the upper connecting pipe 1 and the tee pipe 2, thereby fixing the inner tube 8 in the tee pipe 2 and the lower connecting pipe 4. The inner tube 8 is provided with a discharge port 802, and the position and size of the discharge port 802 correspond to the discharge pipe 5.

[0042] Working principle:

[0043] When soil samples need to be collected, the motor 7 is first started. The motor 7 is installed at the top end of the upper connecting pipe 1 through the fixing plate 6, ensuring stable operation of the motor 7.

[0044] The output end of the motor 7 is connected with the auger drive. When the motor 7 is started, the auger starts to rotate in the upper connecting pipe 1. The design of the helical blade of the auger enables it to effectively push the soil sample into the inner pipe 8.

[0045] With the rotation of the auger, the soil sample is gradually pushed into the inner pipe 8. The inner pipe 8 is inserted into the insertion slot in the three-way pipe 2 and the lower connecting pipe 4 through the limiting rib 803, ensuring the stable position of the inner pipe 8.

[0046] When the soil sample is pushed to the top of the inner pipe 8, since the position and size of the discharge port 802 correspond to the discharge pipe 5, the soil sample will enter the discharge pipe 5 through the discharge port 802 and finally be discharged into the external container.

[0047] After the sampling is completed, the inner pipe 8 can be disassembled to clean the residual soil sample inside. Since the inner pipe 8 is designed to be detachable, the cleaning process becomes simple and fast.

[0048] The lower connecting pipe 4 of the device can be replaced with components of different lengths to adapt to the needs of soil sampling at different depths. By adjusting the length of the lower connecting pipe 4, the sampling depth can be easily controlled.

[0049] The three-way pipe 2 is provided with a sealing ring between the upper connecting pipe 1, the lower connecting pipe 4 and the discharge pipe 5, and is locked and fixed by the clamp 3. This design ensures that the connection between the components is stable and reliable, avoiding loosening and leakage problems during sampling.
