Description

Technical Field

[0001] This application relates to the field of geological sampling device technology, and in particular to a geological groove sampling device for underground roadways. Background Technology

[0002] Geological groove sampling is an important method for obtaining rock or ore samples in geological exploration. Its purpose and significance mainly revolve around core needs such as geological information acquisition and resource evaluation. By carving grooves of specific dimensions (such as length, width, and depth) on ore bodies or rock outcrops, continuous and uniform samples are collected to reflect the material composition, structure, and mineralization characteristics of the geological body. For example, grooves carved at ore outcrops can systematically collect ore samples for analyzing the content and distribution of useful elements (such as gold, copper, and iron). Furthermore, laboratory analysis of grooved samples (such as chemical analysis and rock and mineral identification) yields key data, such as ore grade, mineral composition, and rock physical and mechanical properties, providing quantitative basis for subsequent resource estimation and engineering design. Currently, there are multiple methods for groove sampling, such as using electric picks and cutting machines.

[0003] Currently, geological grooving sampling in underground tunnels involves marking the sampling location with paint, laying a plastic sheet at the bottom of the tunnel to receive the sample, and then using an electric pick, cutting machine, or manual hammering to groove the sample. During the grooving process, factors such as operator error and equipment vibration can easily cause the grooving boundary to deviate, resulting in a discrepancy between the actual sampling area and the predetermined area. This is especially true on inclined or curved tunnel walls, where it is difficult to guarantee the straightness and standardization of the grooving direction, leading to a decrease in sample representativeness. Because the plastic sheet or canvas is laid at the bottom of the tunnel, there is a certain height difference between it and the grooving area. Rock samples generated during grooving are easily splashed outside the receiving device during their fall, causing sample loss. Simultaneously, the plastic sheet is in direct contact with the tunnel floor, easily contaminating the sample with scum, dust, water, and other impurities, affecting the accuracy of the analysis results. After sampling, the plastic sheet must be manually collected and the sample transferred, creating redundant steps and increasing underground operation time and labor costs. Utility Model Content

[0024] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 The underground tunnel geological grooving sampling device shown includes: a base plate 1 and four side plates 2 inserted and installed on the base plate 1. The base plate 1 has four U-shaped grooves for installing the side plates 2, and an elastic layer is provided inside the U-shaped grooves. The side plates 2 are positioned based on the elastic layer after being inserted into the U-shaped grooves. The side plates 2 and the base plate 1 form a rectangular box with an open top. Adjacent side plates 2 are connected by movable buckles 9, and the side plates 2 have mounting holes and slots corresponding to the movable buckles 9. Figure 3 As shown, the movable buckle 9 includes a fixing member 91 and a movable member 93 connected to the end of the fixing member 91 via a rotating shaft 92. Fixing holes are provided on the fixing member 91 and the movable member 93, and the wedge-shaped locking head of the movable member 93 is matched with the locking groove.

[0026] Assuming the two metal plates to be connected are designated as Plate A and Plate B, the left edge of Plate A has pre-drilled mounting holes corresponding to the bolt holes of fastener 91. The right edge of Plate B has a rectangular groove, with the serrated groove at the bottom of the groove perfectly matching the anti-slip teeth on the wedge-shaped head of movable component 93. When connecting Plate A and Plate B, rotating movable component 93 allows the wedge-shaped head to insert into the groove of Plate B. At this point, the anti-slip teeth and the serrated groove interlock, and then bolts and nuts are used to secure the connection, achieving a stable connection between the two plates. This design ensures a tight connection while allowing for simple assembly and disassembly, adapting to the actual needs of downhole operations.

[0027] A bubble level and a scale 7 are installed on the rectangular box. A handle 6 is installed on the top, and a rotating hook 5 is connected to the handle 6 based on a bearing. A triangular metal plate is welded to each of the two side plates 2 of the rectangular box as a connecting piece. The handle 6 is a stainless steel round rod, with both ends connected to the middle sections of the triangular plates on both sides. A through hole is opened in the middle of the triangular plate. After the two ends of the handle 6 are inserted into the through hole, they are locked by radially penetrating screws. The ends of the screws are embedded in the annular grooves on the surface of the handle 6 to prevent the handle 6 from sliding axially, and can be separated by removing the screws. A bearing seat is welded to the top of the triangular plate. The bearing seat is a cylindrical sleeve perpendicular to the surface of the triangular plate. A miniature deep groove ball bearing is embedded in the sleeve, and the outer ring is interference-fitted with the bearing seat. A rotating shaft 92 is welded to the base of the rotating hook 5. After the rotating shaft 92 passes through the inner ring of the bearing, the end is limited by a shaft elastic retaining ring, so that the hook can rotate around the bearing. One rotating hook 5 is installed at the top of each triangle, and the opening direction can be freely adjusted.

[0028] A discharge port is provided in the middle of the bottom plate 1 of the rectangular box, and two feed plates 3 are installed inside the rectangular box corresponding to the discharge port, such as... Figure 2 The feed plate 3 shown includes an inclined plate and a horizontal plate connected to the bottom of the inclined plate. The horizontal plate has corresponding connection holes to the base plate 1. An elastic strip is provided at the other end of the feed plate 3 via bolts. After the feed plate 3 is placed inside the rectangular box, the elastic strip is compressed, fixing the highest end of the feed plate 3 to the middle of the inner wall of the side plate 2. The two feed plates 3 are mirror-mounted to form a V-shaped structure, with the discharge port located between the two feed plates 3. A movable plate 4 is installed at the bottom of the rectangular box corresponding to the discharge port. The movable plate 4 has an n-shaped structure and a magnetic strip 41 at the bottom that connects to the base plate 1. During installation, it is directly attached to the metal base plate 1. During discharge, the movable plate 4 is removed, leaving the discharge port uncovered, and the material falls from the discharge port.

[0029] The usage process of the device is as follows: 1. Assemble the device: After inserting the side plate 2 into the base plate 1, complete the assembly by fixing the movable buckles 9 between the metal plates. (After use, it can be disassembled in the same way for easy storage; after disassembly, it resembles a cardboard box structure.) 2. After determining the sampling location in the tunnel, clean the surface scum, dust, etc. of the sampling area. 3. Hang the sampling device horizontally below the sampling location, close to the tunnel (adjust the level by observing the bubble level 8). If hanging it on the anchor net, it can be fixed with construction rivets. 4. Perform groove sampling, read the sampling length and sampling direction, and record them. 5. After the groove sampling of a single sample is completed, remove the bottom movable plate 4 and put the sample into the sample bag.
