Description

Technical Field

[0001] This utility model relates to a geological exploration sampling device, belonging to the technical field of exploration and sampling equipment. Background Technology

[0002] During geological exploration, it is often necessary to drill and sample the surface soil of the earth's crust, and then use professional analytical instruments to test and analyze the composition of the sampled soil. Therefore, soil sampling equipment is needed to sample the local soil during geological exploration.

[0003] Most soil sampling devices designed in related technologies include a handle and a sampling tube connected to the handle. The sampling tube is open at the bottom and has a circular cross-section. When sampling soil, the tube is inserted into the soil by holding the handle, allowing soil to enter the tube. The tube is then pulled out, thus collecting the soil sample. However, in geological exploration, it is sometimes necessary to sample and observe soil from different soil layers within a certain area. Analyzing soil at different depths yields more comprehensive data. Currently, most soil sampling methods involve inserting a sampling tube into the ground, removing the tube, storing the soil, and then repeating the process at different depths. This back-and-forth operation is time-consuming, labor-intensive, cumbersome, and reduces overall work efficiency.

[0004] Furthermore, existing soil sampling equipment suffers from several drawbacks during the sampling process. Because the bottom of the sampling tube is open, soil samples may fall due to gravity as the tube rises. Simultaneously, soil from the inner wall of the sampling hole may fall to the bottom when the tube is removed, causing mixing of soil samples from different depths and affecting survey data. This makes it unsuitable for sampling deeper or looser soils. For more compacted or cohesive soil layers, soil may adhere to the inside of the sampling tube after sampling, requiring repeated tapping of the tube to remove the sample. This presents challenges in sample removal and cleaning of the inner wall of the sampling tube, resulting in inconvenient operation, increased workload for staff, low sampling efficiency, poor stability, and ultimately, unsuitability for practical use. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a geological exploration sampling device.

[0006] The technical solution adopted by this utility model is as follows: a geological exploration sampling device is designed, which includes a drill rod, a sampling rod, a sampling plate, a hand-tightening bolt and a handle. The sampling rod is rotatably mounted on the drill rod. Multiple sampling plates are provided on the sampling rod. Sampling grooves are provided on the drill rod corresponding to the positions of the sampling plates. The upper end of the sampling rod is connected and fixed to the handle. The handle and the drill rod are fixed together by the hand-tightening bolt.

[0007] Furthermore, the bottom of the sampling groove is set to be arc-shaped, and the sampling piece is an arc-shaped piece.

[0008] Furthermore, a sleeve is provided on the drill rod, one side of the sleeve is embedded in the drill rod, the sleeve and the sampling groove are alternately arranged along the axial direction of the drill rod, and the sampling rod is installed inside the sleeve.

[0009] Furthermore, the sampling rod is a hexagonal prism rod, and a connecting cylinder is provided at one end of the sampling piece. The connecting cylinder is provided with a hexagonal prism hole, and the sampling rod is connected to the sampling piece through the hexagonal prism hole.

[0010] Furthermore, the handle has a threaded through hole and a threaded blind hole in the middle, the sampling rod has a stud at the upper end, the upper end of the sampling rod is installed in the threaded blind hole and threadedly connected and fixed thereto, the drill rod has a threaded hole at the upper end that aligns with the threaded through hole on the handle, and the hand-tightening bolt is connected to the threaded through hole and the threaded hole respectively to connect the handle to the drill rod.

[0011] Furthermore, the sampling plate has sampling teeth at the other end opposite to the connecting cylinder, the lower end of the drill rod is a tapered structure, and the outer surface of the tapered structure is threaded.

[0012] Furthermore, the bottom end of the sleeve located at the lowest point of the drill pipe is configured as a closed conical tip.

[0013] Furthermore, the grip is a cylindrical rod with flattened notches on the upper and lower sides of its middle section to form a flat plate structure in the middle. The threaded through hole and the threaded blind hole are respectively provided on the flat plate structure.

[0014] Furthermore, anti-slip rubber sleeves are provided at both ends of the grip, and the outer circumferential array of the anti-slip rubber sleeves is provided with dense anti-slip protrusions.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention, by setting multiple sampling slots on the drill rod and equipping it with sampling rods and sampling plates, allows for simultaneous and independent collection of soil samples from different depths. This enables the acquisition of comprehensive samples in a single operation, saving time and effort, and improving overall work efficiency. Sampling different soil layers independently prevents interference during collection and extraction, facilitating more precise analysis of soil samples at different depths and obtaining more comprehensive and accurate data.

[0017] Furthermore, because the sampling trough is not only sealed at the bottom but also forms a semi-enclosed structure with the sampling plate, the soil sample will not fall due to its own gravity during the upward movement of the sampling device when it is removed. This also prevents soil from the inner wall of the sampling hole from falling to the bottom, thus avoiding mixing of soil samples from different depths and affecting the survey data (this application obtains soil samples from the walls of different depths of the sampling hole). Moreover, this application allows for the discharge of soil samples from the sampling trough by rotating the sampling plate, which is simple, convenient, and effective, preventing soil from adhering to the inside of the sampling trough (if any soil adheres to the sampling plate, it is easy to clean since the sampling plate has been rotated out of the sampling trough). This application is suitable for sampling various environmental soil layers, is easy to operate, greatly reduces the burden on workers, and has high sampling efficiency and good stability, making it beneficial for practical use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1: As Figure 1-2 As shown, a geological exploration sampling device includes a drill rod 1, a sampling rod 2, sampling plates 3, a hand-tightening bolt 6, and a handle 4. The sampling rod 2 is rotatably mounted on the drill rod 1, meaning it is installed on and can rotate. Multiple sampling plates 3 are mounted on the sampling rod 2, and these plates rotate with the sampling rod 2. Sampling slots 5 are provided on the drill rod 1 corresponding to the positions of the sampling plates 3. Initially, the sampling plates 3 are positioned on one side within the sampling slots 5. During rotation, the sampling plates 3 pass through the sampling slots 5. The upper end of the sampling rod 2 is connected and fixed to the handle 4, and the handle 4 is fixed to the drill rod 1 by the hand-tightening bolt 6. After inserting the sampling device into the formation, the portion of the drill rod 1 that the hand-tightening bolt 6 is removed, and then the handle 4 is gripped and rotated to rotate the sampling rod 2, thereby rotating the sampling plates 3 one revolution. This allows soil samples from different depths to be driven into the corresponding sampling slots 5.

[0029] In this embodiment, the bottom of the sampling groove 5 is set to be arc-shaped, so that the sampling piece 3 always stays flush with the bottom of the sampling groove 5 during rotation. The sampling groove 5 is appropriately sized while ensuring the structural strength of the drill rod 1. The sampling piece 3 is arc-shaped, which facilitates its insertion into the soil layer to obtain soil samples during rotation, and also matches the notch on one side of the sampling groove 5, thereby reducing soil sample loss during sampling.

[0030] Example 2: This example is based on Example 1 and provides a way to rotatably mount the sampling rod 2 on the drill rod 1.

[0031] Specifically, the drill rod 1 is provided with a sleeve 7, such as... Figure 4 As shown, one side of the sleeve 7 is embedded in the drill rod 1, which strengthens the connection between the sleeve 7 and the drill rod 1 and reduces the volume of the sleeve 7, sampling rod 2 and other components protruding from the drill rod 1, making it easier for the sampling device to insert and remove the soil layer. The sleeve 7 and the sampling groove 5 are alternately arranged along the axial direction of the drill rod 1 to ensure a stable and reliable connection between the sleeve 7 and the sampling rod 2. The sampling rod 2 is installed inside the sleeve 7.

[0032] Example 3: This example, based on Example 2, provides a connection structure for the sampling rod 2 and the sampling piece 3, specifically as follows:

[0033] In this embodiment, the sampling rod 2 is a hexagonal prism rod, such as... Figure 5 As shown, one end of the sampling piece 3 is provided with a connecting cylinder 8, such as... Figure 6 As shown, the connecting cylinder 8 has a hexagonal prism hole (the sleeve 7 on the drill rod 1 has a cylindrical hole, and the sampling rod 2 can rotate inside it). The sampling rod 2 is connected to the sampling piece 3 through the hexagonal prism hole, thereby driving the sampling piece 3 to rotate. At the same time, it is easy to separate the sampling rod 2 and the sampling piece 3, which is beneficial for later maintenance and use.

[0034] Example 4: This example further refines the connection structure between the handle 4, the sampling rod 2, and the drill rod 1, based on Example 3. Specifically, the handle 4 has a threaded through hole 9 and a threaded blind hole 10 in the middle. Figure 3 As shown, the upper end of the sampling rod 2 is provided with a stud, and the upper end of the sampling rod 2 is installed in the threaded blind hole 10 and threadedly connected and fixed thereto. The upper end of the drill rod 1 is provided with a threaded hole that aligns with the threaded through hole 9 on the handle 4. The hand-tightening bolt 6 is connected to the threaded through hole 9 and the threaded hole respectively to connect the handle 4 and the drill rod 1, which facilitates quick assembly and disassembly.

[0035] Example 5: This example is a further optimization and refinement of the sampling device structure based on Example 4, specifically as follows:

[0036] The geological exploration sampling device described in this embodiment has sampling teeth 11 on the other end of the sampling plate 3, which is opposite to the connecting cylinder 8. This facilitates the insertion of the sampling plate 3 into the soil layer when it rotates to take samples. The lower end of the drill rod 1 is set with a conical structure, which facilitates the downward insertion of the entire sampling device into the soil layer. The outer surface of the conical structure is provided with a threaded structure. When it is difficult to push the sampling device with vertical force, a rotational pushing method can be used. At this time, the threaded structure at the lower end of the drill rod 1 helps the sampling device to rotate.

[0037] In this embodiment, the bottom end of the sleeve 7 located at the lowest end of the drill rod 1 is set as a closed conical tip, which facilitates the insertion of the sampling device into the soil layer.

[0038] In this embodiment, the handle 4 is a cylindrical rod, which is easy to make from readily available materials. The upper and lower sides of the middle part are respectively provided with flat notches 12 to form a flat plate structure in the middle part, which facilitates its connection and fit with the drill rod 1 and the sampling rod 2, and also facilitates the connection and fixation of the hand-tightened bolt 6. The threaded through hole 9 and the threaded blind hole 10 are respectively provided on the flat plate structure.

[0039] In this embodiment, anti-slip rubber sleeves 13 are respectively provided at both ends of the grip 4. The anti-slip rubber sleeves 13 are arranged with dense anti-slip protrusions in an array on the outer periphery, so that the sampling device can be operated better by the staff through the anti-slip rubber sleeves 13.

[0040] During assembly, the sampling rod 2 is first installed on the handle 4, and then the sampling rod 2 is inserted along the sleeve 7 on the drill rod 1. During the process, the sampling piece 3 is placed at the sampling groove 5 and the sampling rod 2 passes through the connecting sleeve 8 on it (the lower end of the sampling rod 2 can also be set into a conical shape to facilitate quick alignment and insertion into the sleeve 7 and the connecting sleeve 8, while nesting with the tip of the sleeve 7 at the lowest end of the drill rod 1). After the sampling rod 2 is inserted into place, the hand-tightening bolt 6 is screwed into the threaded through hole 9 of the handle 4 until it is screwed into the threaded hole on the drill rod 1 a certain distance or slightly tightened.

[0041] When using this application, after inserting the sampling device into the required depth of the stratum, unscrew the portion of the hand-tightening bolt 6 that is screwed into the drill rod 1, then hold the handle 4 and rotate it to drive the sampling rod 2 to rotate, thereby causing the sampling disc 3 to rotate one revolution (initially, the sampling disc 3 is located on one side of the sampling groove 5), thus driving soil samples from different depths into the corresponding sampling groove 5. Then, reset the hand-tightening bolt 6, remove the sampling device, and retrieve and store all soil samples from the sampling grooves 5. When retrieving soil samples from the sampling grooves 5, you can also unscrew the portion of the hand-tightening bolt 6 that is screwed into the drill rod 1 again, then rotate the sampling rod 2, and use the sampling disc 3 to drive the soil samples out of the sampling grooves 5. This method is simple, convenient, more efficient, and results in more complete soil sample retrieval.

[0042] Furthermore, in the description of this utility model, unless otherwise stated, the terms "multiple," "multiple roots," and "multiple groups" mean two or more, and "several," "several roots," and "several groups" mean one or more. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used only for descriptive purposes and should not be construed as indicating or implying relative importance.

[0043] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings.
