Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, specifically to a direct-push soil sampling guide rail support. Background Technology

[0002] In many fields such as environmental monitoring and geotechnical engineering, there are strict requirements for soil sample collection, especially the need for "undisturbed and high-precision" soil samples to accurately analyze key information such as soil composition and pollutant distribution. However, existing soil sampling methods and equipment have many limitations.

[0003] Early mechanical methods such as auger drilling and impact sampling could easily damage the original soil structure during the sampling process, resulting in distorted samples that could not accurately reflect the original state of the soil and thus affect the accuracy of subsequent analysis results.

[0004] While manual or semi-automatic equipment can perform soil sampling to some extent, they are highly dependent on human operation. In complex geological conditions, it is difficult for humans to quickly and effectively advance the sampling equipment into deep soil layers, resulting in low sampling efficiency and difficulty in ensuring sample quality and integrity.

[0005] Traditional soil sampling equipment has poor adaptability in complex terrain. For example, when rapidly obtaining stratified soil samples at contaminated sites, the vertical accuracy of the guide rail directly affects the accuracy of pollutant distribution analysis. Existing equipment lacks a stable guiding device, relies on manual leveling, which is time-consuming and inaccurate. It is also prone to cumulative errors during long-distance advancement and has poor vibration resistance in complex strata. During sampling, the sampling tube is prone to tilting, which not only leads to inaccurate sample location but also affects the vertical distribution characteristics of the samples, significantly reducing the reliability of the data based on the samples. Utility Model Content

[0006] The purpose of this utility model is to provide a direct-push soil sampling guide rail support to solve the problems of poor adaptability, lack of stable guiding device, reliance on manual leveling, time-consuming and low accuracy of existing soil sampling equipment, and the tendency of the sampling tube to deviate during the sampling process, resulting in inaccurate sample position and affecting sample quality and integrity.

[0007] A direct-push soil sampling guide rail support includes a guide rail base, a guide rail track on the side wall of the guide rail base, two sliders symmetrically sliding on both sides of the guide rail track, a sliding bracket fixedly provided on the side wall of the slider, and a guide component on the guide rail base that can drive the sliding bracket to move vertically.

[0008] Preferably, the guide assembly includes a drive connection assembly fixedly mounted on the top of the guide rail base, a bottom bearing fixedly mounted on the bottom of the guide rail base, a power screw shaft rotatably mounted between the bottom bearing and the drive connection assembly, a power bearing mounted on the top of the drive connection assembly, a motor mounted inside the power bearing, the output end of the motor being drivenly connected to the top of the power screw shaft, a movable block being threadedly connected to the shaft body of the power screw shaft, and the side wall of the movable block being fixedly connected to the side wall of the sliding bracket.

[0009] Preferably, the sliding bracket has a support plate on its side wall, and the support plate is made of a high-hardness material.

[0010] Preferably, the sliding bracket has working protection plates on both sides of the bearing plate on its sidewall.

[0011] Preferably, a support base is fixedly provided at the bottom of the guide rail base.

[0012] The advantages of this utility model are as follows: The direct-push soil sampling guide rail bracket of this utility model, by setting a guide component, utilizes the high-precision linear contact between four sets of sliders and the guide rail to form a stable motion constraint, effectively offsetting the lateral torque and vibration generated during drill bit operation, ensuring that the sliding bracket can only move along the extension direction of the guide rail, preventing deviation of the motion trajectory, and the self-locking thread of the spiral lifting nut and the guide rail can automatically maintain the sampling depth when the power is off, preventing sample slippage, and the clamping structure formed by the working protection plate further suppresses lateral vibration, protecting the working drill bit from damage caused by other external factors, so that the guide rail can continuously maintain the vertical guiding function, reduce the transmission rate of drill vibration, and avoid working errors.

Detailed Implementation

[0015] 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.

[0016] like Figures 1 to 3As shown, a direct-push soil sampling guide rail support includes a guide rail base 100, a guide rail track 101 on the side wall of the guide rail base 100, and sliders 104 symmetrically slidingly engaged on both sides of the guide rail track 101. A sliding bracket 201 is fixedly provided on the side wall of the slider 104, and a guide component is provided on the guide rail base 100 that can drive the sliding bracket 201 to move vertically.

[0017] In this embodiment, the guiding assembly includes a drive connection assembly 102 fixedly mounted on the top of the guide rail base 100. A bottom bearing 106 is fixedly mounted on the bottom of the guide rail base 100. A power spiral shaft 105 is rotatably mounted between the bottom bearing 106 and the drive connection assembly 102. A power bearing 103 is mounted on the top of the drive connection assembly 102. A motor is mounted inside the power bearing 103. The output end of the motor is connected to the top of the power spiral shaft 105. A moving block 108 is threadedly connected to the shaft of the power spiral shaft 105. The side wall of the moving block 108 is fixedly connected to the side wall of the sliding bracket 201.

[0018] When the motor inside the power bearing 103 starts, it drives the power screw shaft 105 to start rotating. Its forward and reverse rotation is converted into the lifting motion of the axial drive device through the screw transmission, which drives the moving block 108 to move. This causes the sliding bracket 201 to start moving in the vertical direction. The sliders 104 symmetrically installed on both sides of the sliding bracket 201 are tightly engaged with the surface of the guide rail 101. The high-precision linear contact between the four sets of sliders 104 and the guide rail 101 forms a stable motion constraint, which effectively counteracts the lateral torque and vibration generated during drill bit operation. The low-friction sliding fit between the sliders 104 and the guide rail 101 ensures that the sliding bracket 201 can only move along the extension direction of the guide rail 101, preventing deviation of the motion trajectory.

[0019] In this embodiment, the side wall of the sliding bracket 201 is provided with a support plate 203, which is made of a high-hardness material.

[0020] The support plate 203 is replaceable. Different support plates 203 are selected according to different drill bit sizes. It is made of high-hardness material to ensure that it will not be damaged by the vibration of the drill bit during operation.

[0021] In this embodiment, a working protection plate 202 is provided on the side wall of the sliding bracket 201 on both sides of the bearing plate 203.

[0022] The clamping structure formed by the working protection plates 202 on both sides further suppresses lateral vibration and can protect the working drill bit from damage caused by interference from other external factors. At this time, the guide rail system continues to maintain the vertical guiding function, so that the rotational power and axial driving force transmitted by the power auger shaft 105 are always accurately transmitted to the drill bit along a straight path until the sampling operation at the predetermined depth is completed.

[0023] In this embodiment, a support base 107 is fixedly provided at the bottom of the guide rail base 100.

[0024] By setting the support base 107 to be firmly fixed on the ground, a rigid support reference surface is formed to prevent the machine from shifting during operation.

[0025] Working process and principle: In use, this device is firmly fixed to the ground by the support base 107, forming a rigid support reference surface. When the motor inside the power bearing 103 starts, it drives the power screw shaft 105 to rotate. Its forward and reverse rotation is converted into the lifting motion of the axial drive device through threaded transmission, driving the moving block 108 to move. This, in turn, causes the sliding bracket 201 to move vertically. The sliders 104 symmetrically installed on both sides of the sliding bracket 201 are tightly engaged with the surface of the guide rail 101. The high-precision linear contact between the four sets of sliders 104 and the guide rail 101 forms a stable motion constraint, effectively... To counteract the lateral torque and vibration generated during drill bit operation, the low-friction sliding engagement between the slider 104 and the guide rail 101 ensures that the sliding bracket 201 can only move along the extension direction of the guide rail 101, preventing deviation of the movement trajectory. When the drill bit touches the ground for sampling, the bearing plate 203 in the middle of the working protection plate 202 supports the drill rod with a high-hardness material. The clamping structure formed by the double working protection plates 202 further suppresses lateral vibration. At this time, the guide rail system continues to maintain the vertical guiding function, so that the rotational power and axial driving force of the power auger shaft 105 are always accurately transmitted to the drill bit along a straight path until the sampling operation at the predetermined depth is completed.

[0026] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
