Description

Technical Field

[0001] This utility model relates to the field of ring cutter holder sampling, and in particular to a stable support for ring cutter sampling. Background Technology

[0002] Ring cutter sampling is a method used to determine soil bulk density. The ring cutter is a specialized tool commonly used for tests such as bulk density, compression, shear, and permeability. The main purpose of ring cutter sampling is to determine the dry density of the soil layer. Dry density reflects the void ratio of the soil and is one of the standards for evaluating the compactness of the soil. In engineering, dry density is often used to control the construction quality of backfill projects and ensure the compaction standard of the soil.

[0003] Traditional sampling methods, such as manual operation or simple machinery, often cause significant soil disturbance, affecting the original structure and properties of the sample. Manual sampling is time-consuming and labor-intensive, especially when dealing with relatively hard soil layers. Operators need to spend a lot of time and energy to complete the sampling task. Manual operation also carries certain safety risks, especially when handling large or heavy tools, which can easily lead to accidental injuries.

[0004] Therefore, traditional sampling methods such as manual operation or simple machinery often lead to significant soil disturbance, affecting the original structure and properties of the sample. Manual operation also poses certain safety risks and is time-consuming and labor-intensive. A method can be designed to place the ring cutter head at the front of the modified equipment and use a hydraulic device to continuously and stably output pressure, thereby reducing disturbance to the original soil and improving sampling efficiency. Utility Model Content

[0005] In order to overcome the problems that traditional sampling methods, such as manual operation or simple machinery, often lead to large soil disturbance, affecting the original structure and properties of the sample, manual operation has certain safety risks, and manual sampling is time-consuming and labor-intensive.

[0006] The technical solution of this utility model is as follows: a stable support for ring knife sampling, including a mounting plate, a connecting frame, a cylinder, a ring knife holder, a sleeve, and a threaded hole; a connecting frame for fixing sampling is fixedly connected to the bottom center of the mounting plate, a cylinder for pushing sampling is provided at the bottom center of the connecting frame, a ring knife holder for stabilizing sampling is provided at the bottom end of the cylinder, a sleeve for easy disassembly and installation is provided at the upper end of the ring knife holder and fixedly connected to the piston end of the cylinder, and a threaded hole for fixing the ring knife holder to the sleeve is provided at the connection between the sleeve and the ring knife holder.

[0007] Preferably, a first screw is provided at the corner of the cylinder away from the ring cutter holder, which is threaded to the connecting frame to further reinforce the connection between the cylinder and the connecting frame. When everything is ready, the cylinder is started, and the compressed air in the cylinder pushes the piston downward, thereby driving the ring cutter holder and the ring cutter to move downward together. Driven by the cylinder, the ring cutter cuts into the soil or other materials at a certain speed and force. When the ring cutter cuts completely into the predetermined depth, the cylinder stops. At this time, the ring cutter contains the required sample. The return function of the cylinder is activated, causing the piston to move upward, driving the ring cutter holder and the ring cutter to rise together. As the ring cutter is pulled out, the sample is completely taken out. The ring cutter is removed from the sleeve, and the sample inside is taken out.

[0008] Preferably, four sets of fixing blocks are installed at the bottom corner of the mounting plate, and a telescopic rod is fixedly connected to the bottom center of the fixing blocks.

[0009] Preferably, a balance column is fixedly connected to the piston end of the telescopic rod, and a fixed column is provided on the side of the balance column away from the balance column.

[0010] Preferably, a load-bearing block is provided between the fixed column and the balance column, and multiple sets of buckles are provided on the outer surface of the telescopic rod from bottom to top.

[0011] Preferably, the surface of the telescopic rod is provided with a fixing hole that is elastically connected to the buckle, a telescopic spring is sleeved on the outside of the buckle, and a spring damper is provided inside the telescopic spring.

[0012] Preferably, the bottom of the buckle is fitted with a clip plate corresponding to the fixing hole, and the threaded hole is threaded with a second screw.

[0013] Preferably, the cylinder is provided with a first screw for threaded connection with the connecting bracket at the corner on the side away from the ring cutter holder, and the outer surface of the connecting bracket is provided with a connecting hole for connection with the cylinder air passage.

[0014] The beneficial effects of this utility model are: compared with the traditional ring knife sampling stable support, this new model is more efficient. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 4 This utility model provides an embodiment of a ring knife sampling stabilizing bracket, including a mounting plate 1, a connecting frame 3, a cylinder 14, a ring knife holder 15, a sleeve 16, and a threaded hole 18; the mounting plate 1 has a connecting frame 3 for fixing the sampling fixedly connected to the bottom center; the connecting frame 3 has a cylinder 14 for pushing the sampling at the bottom center; the cylinder 14 has a ring knife holder 15 for stabilizing the sampling at the bottom end; the ring knife holder 15 has a sleeve 16 fixedly connected to the piston end of the cylinder 14 for easy disassembly and installation at the upper end; and a threaded hole 18 is provided at the connection between the sleeve 16 and the ring knife holder 15 for fixing the ring knife holder 15 to the sleeve 16.

[0022] Please see Figure 1 - Figure 2 In this embodiment, four sets of fixing blocks 2 are installed at the bottom corner of the mounting plate 1. A telescopic rod 5 is fixedly connected to the bottom center of the fixing block 2. The four fixing blocks 2 are distributed at the four corners of the mounting plate 1, providing a wider support area and greatly enhancing the stability of the entire device. The telescopic rod 5 can be height-adjusted according to the actual terrain, enabling the equipment to be used in various environments, whether it is a flat laboratory or a complex field environment. Stable support reduces the vibration and shaking of the equipment during operation, thereby reducing wear between components and extending the service life of the equipment. When not in use, the telescopic rod 5 can be retracted, making the entire equipment more compact and convenient for transportation and storage. A balance column 7 is fixedly connected to the piston end of the telescopic rod 5. A fixed column 9 is provided on the side of the balance column 7 away from the balance column 7. The height adjustment function of the telescopic rod 5, combined with the design of the balance column 7 and the fixed column 9, enables the equipment to be used under different heights and terrain conditions. Even on slopes or uneven ground, the equipment can be kept level and stable by adjusting the position of the telescopic rod 5 and the fixed column 9. The balance column 7 and the fixed column 9 work together to provide additional support points and enhance the stability of the entire device. Especially on uneven or soft ground, this design can effectively prevent the equipment from tilting or tipping over.

[0023] Please see Figure 2 - Figure 3In this embodiment, a load-bearing block 8 is provided between the fixed column 9 and the balance column 7. Multiple sets of buckles 6 are provided on the outer surface of the telescopic rod 5 from bottom to top. The load-bearing block 8 is located between the fixed column 9 and the balance column 7, increasing the weight of the entire device and thus improving its stability. The extra weight can effectively prevent the equipment from shaking or moving during operation. The weight of the load-bearing block 8 can increase the friction between the equipment and the ground, providing better grip and reducing the risk of slipping due to wet or soft ground. The surface of the telescopic rod 5 is provided with a fixing hole 11 that is elastically connected to the buckle 6. A telescopic spring 10 is sleeved on the outside of the buckle 6. A spring damper is provided inside the telescopic spring 10. Preferably, a locking plate 12 corresponding to the fixing hole 11 is installed at the bottom of the buckle 6. A second screw 17 is threadedly connected to the threaded hole 18. This multi-point locking mechanism ensures the stability of the equipment at different height settings. Especially on uneven or soft ground, the combined design of the telescopic spring 10 and the spring damper can effectively absorb and disperse external vibrations, reduce the shaking of the equipment during operation, and improve the safety of operation.

[0024] Please see Figure 3 - Figure 4 In this embodiment, a locking plate 12 corresponding to the fixing hole 11 is installed at the bottom of the buckle 6, and a second screw 17 is threadedly connected to the threaded hole 18. The locking plate 12 at the bottom of the buckle 6 cooperates with the fixing hole 11 on the surface of the telescopic rod 5 to provide the first layer of locking. By inserting the locking plate 12 into the fixing hole 11, the stability of the buckle 6 in the selected position is ensured. Based on the buckle 6 and the fixing hole 11, the threaded hole 18 and the second screw 17 are used for secondary locking. This double locking mechanism greatly enhances the stability of the telescopic rod 5 at different height settings and prevents slippage or loosening caused by external force or vibration. The combination design of the plate and the second screw 17 can effectively prevent the buckle 6 from loosening accidentally during use, especially during long-term operation or in complex environments, ensuring that the equipment always maintains stable support. The cylinder 14 is provided with a first screw 13 threadedly connected to the connecting frame 3 at the corner away from the ring cutter frame 15. The outer surface of the connecting frame 3 is provided with a connecting hole 4 connected to the air passage of the cylinder 14. The cylinder 14 is provided with a first screw at the corner away from the ring cutter frame 15. 13. The cylinder 14 is firmly fixed to the connecting frame 3 by a threaded connection. This multi-point fixing structure design greatly enhances the connection strength between the cylinder 14 and the connecting frame 3, ensuring the stability of the entire device during operation. The multi-point fixing design makes the connection between the cylinder 14 and the connecting frame 3 more stable, reducing the operational risks caused by the loosening or displacement of the cylinder 14 and improving the overall operational safety. The design of the first screw 13 makes the installation and disassembly of the cylinder 14 more convenient and quick. Users can quickly replace or repair the cylinder 14 as needed, reducing maintenance time and costs.

[0025] During operation, first, fix the mounting plate 1 in a suitable position, and adjust the height of the telescopic rod 5 as needed to achieve optimal stability of the entire device. Adjusting the buckle 6 and telescopic spring 10 ensures the device's stability under different terrain conditions. Rotating the buckle 6 fixes the clamping plate 12 in the fixing hole 11. The ring cutter holder 15 is connected to the piston end of the cylinder 14 via the sleeve 16, and the ring cutter holder 15 is securely fixed to the sleeve 16 using the threaded hole 18 and the second screw 17, ensuring all connection points are tight and secure. The cylinder 14 is connected to the air source via the connecting hole 4 to ensure unobstructed airflow. A screw thread is provided at the corner of the cylinder 14 away from the ring cutter holder 15, connecting to the connecting bracket 3. The first screw 13, which is connected by a threaded joint, further strengthens the connection between the cylinder 14 and the connecting frame 3. When everything is ready, the cylinder 14 is started. The compressed air in the cylinder 14 pushes the piston downward, thereby driving the ring cutter holder 15 and the ring cutter to move downward together. Driven by the cylinder 14, the ring cutter cuts into the soil or other materials at a certain speed and force. When the ring cutter has completely cut into the predetermined depth, the cylinder 14 stops. At this time, the ring cutter contains the required sample. The return function of the cylinder 14 is started, causing the piston to move upward, driving the ring cutter holder 15 and the ring cutter to rise together. As the ring cutter is pulled out, the sample is completely taken out. The ring cutter is removed from the sleeve 16, and the sample inside is taken out.

[0026] Through the above steps, the cylinder 14 provides stable power, ensuring that the ring cutter can cut vertically and evenly into the sample, reducing deviations caused by manual operation. The components such as the fixing block 2, telescopic rod 5, balance column 7, and load-bearing block 8 work together to increase the stability of the entire device and reduce the risk of tilting or tipping over during operation. The detachable design between the sleeve 16 and the ring cutter holder 15 facilitates the replacement of different ring cutters or maintenance. The combination of the buckle 6, telescopic spring 10, and spring damper allows the telescopic rod 5 to be easily adjusted between different heights to adapt to different working environments and needs. The use of the first screw 13 and the second screw 17 simplifies the assembly and disassembly process, making the equipment easy to transport and set up. This solves the problems that traditional sampling methods such as manual operation or simple machinery often lead to large soil disturbance, affecting the original structure and properties of the sample. Manual operation also poses certain safety risks and is time-consuming and labor-intensive.
