Description

Technical Field

[0001] This utility model relates to the field of sampling drill bit technology, and in particular to a sampling drill bit mechanism with soil shaping and soil sampling function to prevent loss. Background Technology

[0002] In many fields, accurate acquisition of soil and rock samples is crucial for subsequent analysis and evaluation. As a key tool for obtaining samples, sampling drill bits are used in geological exploration to analyze soil and rock samples from different strata, revealing underground geological structures and providing a basis for finding potential mineral resources. In construction engineering, testing soil and rock samples at construction sites helps assess the bearing capacity of the foundation and ensures the safe construction of projects. With social development and progress, various industries have increasingly higher requirements for the accuracy and detail of geological information, which has prompted continuous innovation and optimization of sampling drill bits to meet increasingly complex operational needs.

[0003] In the early days, due to limitations in technology and equipment, operators manually rotated a drill rod with helical blades to drill into the ground. As the helical blades rotated, soil and rock debris were gradually brought to the surface, thus completing the collection of shallow samples. This method was simple to operate and inexpensive, but extremely inefficient and only suitable for shallow, soft soil. With the development of technology, sampling drill bit mechanisms have been significantly improved and diversified. Modern hydraulically driven sampling drills are widely used. These drills are equipped with powerful hydraulic structures that provide stable and strong power to the drill bit, enabling it to drill into various strata efficiently. However, during the sample extraction process, the sample is not easily separated from the surrounding rock and soil layers, and the separated sample is prone to falling out of the drill rod, greatly increasing the difficulty and complexity of sampling. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sampling drill bit mechanism with soil shaping and anti-loss function, which aims to improve the problem that the sample is not easy to separate from the surrounding rock and soil layers in the existing technology, and the separated sample is easy to fall out of the drill rod, which greatly increases the sampling difficulty and complexity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-loss sampling drill bit mechanism with soil shaping and sampling function, comprising a main body, a control mechanism provided at the upper end of the inner wall of the main body for controlling sampling, and a sampling mechanism provided at the bottom of the main body for excavating and sampling soil.

[0006] The control mechanism includes a first fixed rod, which is fixed to the middle of the inner wall of the main body. Multiple rotating components are provided on the outer wall of the first fixed rod. A sealing ring is provided on the outer wall of each rotating component. A transition component is provided at the top of each rotating component. A power component is provided in the middle of the transition component. A second fixed rod is fixedly connected to the upper end of the inner wall of the main body. A soil discharge component is provided at the upper end of the outer wall of the main body. A limit post is fixedly connected to the middle of the first fixed rod.

[0009] As a further description of the above technical solution:

[0010] The rotating assembly includes a rotating ring, the inner wall of which is rotatably connected to the outer wall of the fixed rod, and a semi-circular blade is fixedly connected to the outer wall of the rotating ring.

[0011] As a further description of the above technical solution:

[0012] The transition component includes a U-shaped block, which is fixed to the top surface of the semi-circular blade. A connecting rod is rotatably connected to the middle of the U-shaped block, and the adjacent ends of the two connecting rods are rotatably connected.

[0013] As a further description of the above technical solution:

[0014] The power assembly includes a second U-shaped block, the middle of which is rotatably connected to one end of a connecting rod. A hydraulic rod is fixedly connected to the top surface of the second U-shaped block, and the other end of the hydraulic rod is fixedly connected to the middle of a second fixed rod.

When the specified depth is reached, the hydraulic rod is extended so that the two semi-circular blades are parallel, and the sealing ring seals the inside of the main body, preventing air from entering. At this point, the drill bit can be removed, and the sample soil can be completely extracted.

The oblique teeth can cut the soil layer by layer, reducing soil disturbance during the soil sampling process. After removing the drill bit, the sampling tube can be removed simply by unscrewing the connector. The sampling tube contains a complete soil sample, achieving shaped soil sampling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a sampling drill bit mechanism with soil shaping and soil extraction function to prevent loss, including a main body 1, a control mechanism 2 is provided at the upper end of the inner wall of the main body 1, the control mechanism 2 is used to control sampling, and a sampling mechanism 3 is provided at the bottom of the main body 1, the sampling mechanism 3 is used for excavation and soil extraction.

[0033] The control mechanism 2 includes a first fixed rod 201, which is fixed to the middle of the inner wall of the main body 1. Multiple rotating components 202 are provided on the outer wall of the first fixed rod 201. A sealing ring 206 is provided on the outer wall of the rotating components 202. A transition component 203 is provided on the top of the rotating components 202. A power component 204 is provided in the middle of the transition component 203. A second fixed rod 208 is fixedly connected to the upper end of the inner wall of the main body 1. A soil discharge component 207 is provided on the upper end of the outer wall of the main body 1. A limit post 205 is fixedly connected to the middle of the first fixed rod 201.

[0034] Specifically, the main body 1 provides a stable working environment and assembly foundation for each component. A control mechanism 2 is installed on the upper inner wall of the main body 1. This control mechanism 2 controls the start and stop of soil sampling during the sampling process to ensure accurate and controllable sampling operations. A sampling mechanism 3 is installed at the bottom of the main body 1. This sampling mechanism 3 is used to penetrate deep into the soil layer for excavation and soil extraction. Simultaneously, it shapes and prevents the loss of the extracted soil samples, ensuring the integrity and originality of the soil samples. The control mechanism 2 includes a fixing rod 201, which is fixed to the middle of the inner wall of the main body 1, providing stable installation and rotation for the rotating assembly 202. A dynamic support point ensures that the rotating component 202 can rotate stably around a fixed axis during operation. Multiple rotating components 202 are installed on the outer wall of the fixed rod 201. These rotating components 202 are used to rotate under power, thereby transporting soil samples inside the main body 1 in preparation for subsequent soil removal. A sealing ring 206 is installed on the outer wall of the rotating component 202 to enhance the sealing between the rotating component 202 and the inner wall of the main body 1, preventing moisture leakage from the soil sample and reducing frictional wear during rotation. The top of the rotating component 202... The control mechanism 2 is equipped with a transition component 203, which transmits the power output from the power component 204 to the rotating component 202 and converts the linear motion of the power component 204 into the circular motion of the rotating component 202. The power component 204 is located in the middle of the transition component 203. The power component 204 provides the power source for the entire control mechanism 2 and drives the transition component 203 and the rotating component 202 by outputting driving force. A fixing rod 208 is fixedly connected to the upper end of the inner wall of the main body 1. The fixing rod 208 is used to fix the power component 204. 04. To provide stable support for the power component 204 and ensure that the power component 204 does not shift during operation, a soil extraction component 207 is provided on the upper part of the outer wall of the main body 1. The soil extraction component 207 is used to extract the soil sample transported by the rotating component 202 to the outside of the main body 1, completing the soil extraction operation after sampling. A limiting column 205 is fixedly connected to the middle of the fixing rod 1 201. The limiting column 205 is used to limit the axial displacement of the rotating component 202 on the fixing rod 1 201, preventing the rotating component 202 from moving up and down during rotation and ensuring the stability of the rotating component 202 during operation.

[0035] Please see the appendix Figure 4 - Appendix Figure 5 The sampling mechanism 3 includes a sampling tube 301, which is disposed on the inner wall of the main body 1. A limit component 302 is disposed on the outer wall of the sampling tube 301. A connector 306 is threadedly connected to the bottom of the inner wall of the main body 1. A drill bit 303 is fixedly connected to the bottom of the connector 306. A soil-draining groove 304 is opened on the outer wall of the drill bit 303. Multiple helical teeth 305 are fixedly connected to the bottom of the drill bit 303.

[0036] Specifically, the sampling mechanism 3 includes a sampling tube 301, which is installed on the inner wall of the main body 1. Its function is to contain the soil sample, shape the soil sample, prevent it from scattering during lifting, and protect it from external contamination. A limiting component 302 is installed on the outer wall of the sampling tube 301 to restrict the direction and range of movement of the sampling tube 301 within the inner wall of the main body 1, ensuring that the sampling tube 301 can only move up and down along a fixed trajectory, preventing deviation and affecting the sampling effect. A connector 306 is threaded to the bottom of the inner wall of the main body 1, enabling a detachable connection between the main body 1 and the drill bit 303, facilitating subsequent adjustments to the drill bit 303. For replacement, repair, or maintenance, the bottom of the connector 306 is fixedly connected to a drill bit 303. As a component that directly contacts the soil, the drill bit 303 is used to break up the soil structure and open a channel for the sampling tube 301 to penetrate into the soil layer. The outer wall of the drill bit 303 is provided with a soil-draining groove 304. The soil-draining groove 304 is used to guide the soil debris broken up by the drill bit 303 into the sampling tube 301, while reducing the resistance of the soil to the drill bit 303 during drilling and improving drilling efficiency. The bottom of the drill bit 303 is fixedly connected to multiple helical teeth 305. The helical teeth 305 enhance the cutting ability of the drill bit 303 on the soil through their sharp structure, especially for harder soil layers, which can quickly break up the soil and increase the drilling speed of the drill bit 303.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 The rotating assembly 202 includes a rotating ring 2021, the inner wall of which is rotatably connected to the outer wall of the fixed rod 201.

The power assembly 204 includes a U-shaped block 2041, the middle of which is rotatably connected to one end of the connecting rod 2032. A hydraulic rod 2042 is fixedly connected to the top surface of the U-shaped block 2041. The other end of the hydraulic rod 2042 is fixedly connected to the middle of the fixed rod 208.

[0038] Specifically, the rotating assembly 202 includes a rotating ring 2021, the inner wall of which is rotatably connected to the outer wall of the fixed rod 201. Its function is to rotate around the fixed rod 201, providing a rotating carrier for the semi-circular blade 2022. The semi-circular blade 2022 is fixedly connected to the outer wall of the rotating ring 2021. During rotation, the semi-circular blade 2022 pushes the soil sample upwards, gradually conveying the soil sample in the sampling tube 301 to the soil extraction assembly 207. The transition assembly 203 includes a U-shaped block 2031, which is fixed to the top surface of the semi-circular blade 2022. Its function is to connect the semi-circular blade 2022 and the connecting rod 2032, providing a rotation fulcrum for the connecting rod 2032. The connecting rod 2032 is rotatably connected to the middle of the U-shaped block 2031. The adjacent ends of rod 2032 are rotatably connected. Rod 2032 is used to transmit power, converting the extension and retraction motion of hydraulic rod 2042 into the circular motion of rotating ring 2021. Power assembly 204 includes U-shaped block 2041. The middle part of U-shaped block 2041 is rotatably connected to one end of connecting rod 2032. Its function is to connect hydraulic rod 2042 and connecting rod 2032 to realize the transition transmission of power. Hydraulic rod 2042 is fixedly connected to the top surface of U-shaped block 2041. Hydraulic rod 2042 outputs power through extension and retraction and is the core power source of power assembly 204. The other end of hydraulic rod 2042 is fixedly connected to the middle part of fixed rod 208. Fixed rod 208 provides fixed support for hydraulic rod 2042 to ensure that hydraulic rod 2042 can stably output power during extension and retraction.

[0039] Please see the appendix Figure 3 - Appendix Figure 5 The excavation component 207 includes an excavation port 2071, which is located on the upper part of the outer wall of the main body 1. A structural column 2072 is fixedly connected to the middle of the inner wall of the excavation port 2071. The outer wall of the sampling tube 301 is fixedly connected to the inner wall of the main body 1. A slide rail 3022 is fixedly connected to the inner wall of the slide rail 3022 and the inner wall of the limiting groove 3021 are slidably connected. A connecting base 4 is fixedly connected to the top of the main body 1. A vent hole 5 is provided on the upper part of the outer wall of the main body 1.

[0040] Specifically, the soil extraction component 207 includes a soil extraction port 2071, which is located on the upper part of the outer wall of the main body 1. Its function is to serve as a channel for discharging soil samples, allowing the transported soil samples to exit from the interior of the main body 1. A structural column 2072 is fixedly connected to the middle of the inner wall of the soil extraction port 2071. The structural column 2072 is used to enhance the structural strength of the soil extraction port 2071 and prevent it from deforming due to the impact of soil samples during long-term use. The limiting component 302 includes a limiting groove 3021. Note: The original text lacked a description of the limiting groove 3021 after "outer wall of sampling tube 301," which is hereby supplemented. The limiting groove 3021 is located on the outer wall of the sampling tube 301. The inner wall of the main body 1 is fixedly connected to the slide rail 3022 to achieve the limiting function. The outer wall of the slide rail 3022 is slidably connected to the inner wall of the limiting groove 3021. The slide rail 3022 provides a guide trajectory for the up and down movement of the sampling tube 301 to ensure the smooth movement of the sampling tube 301. The top of the main body 1 is fixedly connected to the connecting base 4, which is used to connect with external drilling equipment. The upper end of the outer wall of the main body 1 is provided with a vent hole 5. The vent hole 5 is used to balance the air pressure inside the main body 1 and the outside, to prevent the formation of negative pressure inside the main body 1 due to the transportation of soil samples, which would affect the normal excavation of soil samples. At the same time, it can also discharge the moisture inside the main body 1 to avoid damage to the components due to moisture.

[0041] Working principle: When sampling soil, the drill bit 303 is installed on the drilling equipment. When drilling, the hydraulic rod 2042 is retracted, causing the U-shaped block 2041 to pull the connection of the two connecting rods 2032. The connecting rod 2032 is connected to the top surface of the semi-circular blade 2022 through the U-shaped block 2031. The semi-circular blade 2022 is rotatably connected to the fixed rod 201 through the rotating ring 2021. That is, the two semi-circular blades 2022 rotate around the fixed rod 201, which opens the channel and the soil drilled downwards enters the main body 1. When it continues to go deeper, the excess soil is discharged from the soil outlet 2071 under the guidance of the semi-circular blades 2022. When the specified depth is reached, the hydraulic rod 2042 is extended, so that the two semi-circular blades 2022 are parallel. The sealing ring 206 seals the inside of the main body 1, preventing air from entering. At this time, the drill bit 303 is removed, and the sample soil can be completely extracted.

[0042] The sampling tube 301 is installed on the inner wall of the main body 1 and is positioned by the limiting groove 3021 and the slide rail 3022. The connector 306 is screwed into the bottom of the main body 1. The top of the connector 306 presses against the bottom of the sampling tube 301 to fix the sampling tube 301. During excavation, the soil dredging groove 304 can discharge the excess soil generated during the soil sampling process, reducing interference with the soil sample. The inclined teeth 305 can cut the soil layer by layer, reducing soil disturbance during the soil sampling process. After the drill bit 303 is removed, the connector 306 can be unscrewed to remove the sampling tube 301. The sampling tube 301 contains a soil sample with a complete shape, realizing the shaping of the soil sample.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
