Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, and in particular to a geological exploration sampling device that can prevent soil erosion. Background Technology

[0002] The field of geological engineering is a pioneering engineering field that takes natural science and earth science as its theoretical foundation, focuses on engineering problems related to geological surveys, mineral resource exploration and prospecting, and the geological structure and geological background of major projects, and uses geology, geophysics and geochemistry, mathematical geology methods, remote sensing technology, testing technology, computer technology and other means to serve the national economic construction.

[0003] The authorized publication number "CN202323035677.2" describes a geological exploration sampling device. It boasts the advantages of precise and complete sampling. Upon reaching the sampling location, a dual-axis motor is activated, driving gears at both ends to rotate. A rack meshing with the gears moves up and down with the rotation. A linkage rod pushes a pressure plate downwards to the bottom of the sampling ring. The dual-axis motor is then turned off, and motors one and two are activated, causing the sampling ring to rotate and move downwards to sample the soil layer. Activating the dual-axis motor again causes the linkage rod to slowly move the pressure plate at its bottom upwards with the extracted soil, gradually increasing the internal space of the sampling ring. The pressure plate remains pressed against the bottom of the soil, preventing the remaining space inside the sampling ring from causing the soil to become loose and disordered, thus maintaining the layered effect of the underground soil. Furthermore, the sampling ring's sidewalls are sealed, preventing the extracted soil sample from falling out, maintaining the integrity of the sample, and improving the accuracy of soil surveying.

[0004] It is difficult to effectively maintain the integrity of the soil structure during the extraction process, especially in loose or moist soil layers. Samples are easily detached or lost from the sampling tool, leading to sampling failure or data distortion. Existing devices lack a protection mechanism for soil stratification, and sampling can easily cause mixing of soil layers at different depths, affecting the accuracy of geological analysis. The spiral drilling method may cause the upper and lower soil layers to separate, exacerbating soil shedding. Therefore, a geological exploration sampling device that can avoid soil shedding is proposed to solve the above problems. Utility Model Content

This invention improves upon existing geological exploration sampling devices that can prevent soil erosion, which are unable to effectively maintain the integrity of the soil structure during extraction, especially in loose or moist soil layers, where samples are easily detached or lost from the sampling tool, leading to sampling failure or data distortion. Existing devices lack a protection mechanism for soil stratification, and sampling can easily cause mixing of soil layers at different depths, affecting the accuracy of geological analysis.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0032] Please see Figures 1-4 The present invention provides the following technical solution:

[0033] Geological survey sampling devices that can prevent soil erosion include:

[0034] Base 1;

[0035] Upper seat 2 is fixedly connected to the upper end of base 1;

[0036] Sampling container 7 is slidably connected to the base 1;

[0037] Hydraulic rod 3 is fixedly connected to the upper inner wall of upper seat 2;

[0038] A conical shovel 8 is fixedly connected to the lower end of the sampling bucket 7;

[0039] Fixed sleeve 9 is fixedly connected to the circumferential surface of sampling barrel 7, and one end of fixed sleeve 9 is fixed to the extended end of hydraulic rod 3.

[0040] Helical blade 12 is rotatably connected to the sampling barrel 7;

[0041] Two sampling slots 10 are provided on the circumferential surface of the fixed sleeve 9.

[0042] Conical head 13 is fixedly connected to the lower end of spiral blade 12;

[0043] Servo motor 16 is fixedly connected to the upper inner wall of fixed sleeve 9, and one end of spiral blade 12 is fixed to the output shaft of servo motor 16.

[0044] In a specific embodiment of this utility model, the base 1 serves as the supporting foundation of the device, and anti-slip textures can be provided on the bottom to enhance stability. The upper base 2 forms a rigid frame. The sampling barrel 7 has a conical shovel 8 at its lower end for cutting into the soil layer. The extended end of the hydraulic rod 3 is connected to the sampling barrel 7 through a fixed sleeve 9, driving the sampling barrel 7 to move up and down. The spiral blade 12 is rotatably connected to the inside of the sampling barrel 7 through a bearing, and a cone head 13 is fixed at its lower end for breaking hard soil layers. The output shaft of the servo motor 16 is connected to the spiral blade 12 to control its rotation speed. The sampling groove 10 is used to collect soil samples at different depths in segments. The cutting edge of the conical shovel 8 is serrated to reduce vibration when cutting into the soil layer and maintain the soil structure. The base 1 is stably placed in the sampling area to ensure the device is level and to avoid sample displacement due to tilting during sampling. The hydraulic rod 3 is activated to push the sampling bucket 7 and the conical shovel 8 vertically downward to cut into the surface soil. The servo motor 16 drives the spiral blade 12 to rotate, and the cone head 13 breaks obstacles. The elastic coating of the spiral blade 12 reduces damage to the soil structure and simultaneously transports the soil upward into the sampling bucket 7. After the soil is carried out by the spiral blade 12, the personnel collect the soil through the sampling trough 10. If multiple sampling is required, the hydraulic rod 3 continues to press down and repeat the above steps. Through process optimization and structural innovation, efficient, accurate and complete geological sampling is achieved, which is especially suitable for complex soil environments.

[0045] Please refer to the details. Figures 1-4 A soil storage box 4 is fixedly connected to the circumferential surface of the fixed sleeve 9. The soil storage box 4 is made of stainless steel.

[0046] In this embodiment: Soil storage box 4 is used to temporarily store loose soil that spills out during the sampling process to prevent the sample from scattering. The stainless steel material ensures its corrosion resistance and structural strength, making it suitable for humid or acidic / alkaline environments in the field.

[0047] Please refer to the details. Figures 1-4 The soil storage box 4 has a circular hole 19 on its lower inner wall. A cylindrical barrel 5 is fixedly connected inside the circular hole 19. A bottom pad 11 is fitted on the circumferential surface of the cylindrical barrel 5.

[0048] In this embodiment: the circular hole 19 is used to install the cylindrical barrel 5. If it is necessary to make the soil columnar, the bottom pad 11 is placed on the circumferential surface of the lower end of the cylindrical barrel 5, and the soil is filled into the cylindrical barrel 5 to fix the shape.

[0049] Please refer to the details. Figures 1-4 The lower end of the support leg of the base 1 is fixedly connected to a fixing plate 14, and the fixing plate 14 is internally threaded with an adjusting bolt 15.

[0050] In this embodiment: the level of the base 1 can be adjusted by rotating the adjusting bolt 15 to ensure that the sampling bucket 7 is pressed down vertically, avoiding sample displacement or device instability caused by tilting. There are four fixing plates 14 and adjusting bolts 15 in this device, which can adjust the height of the four legs to facilitate use in different regions.

[0051] Please refer to the details. Figures 1-4 A groove 6 is provided on one side of the inner wall of the upper seat 2, and a slider 20 is fixedly connected to the surface of the fixed sleeve 9. The slider 20 is slidably connected in the groove 6.

[0052] In this embodiment, the slide groove 6 and the slider 20 form a sliding assistance function, which restricts the fixed sleeve 9 to move only in the vertical direction, prevents the hydraulic rod 3 from deflecting when pushed, and ensures the linear motion accuracy of the sampling bucket 7.

[0053] Please refer to the details. Figures 1-4 The bottom pad 11 is made of rubber.

[0054] In this embodiment, the rubber base pad 11 has high elasticity and wear resistance, which can not only buffer the impact of soil, but also seal the connection gap between the cylindrical barrel 5 and the soil storage box 4 to prevent the leakage of fine particles.

[0055] Please refer to the details. Figures 1-4 A fixing ring 17 is fixedly connected to the circumferential surface of the servo motor 16, and a support rod 18 is fixedly connected between the fixing ring 17 and the fixing sleeve 9.

[0056] In this embodiment, the fixed ring 17 and the support rod 18 form a rigid support structure, which disperses the vibration load of the servo motor 16, avoids the connection between the motor shaft and the spiral blade 12 from loosening due to long-term operation, and improves the transmission stability.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
