Description

Technical Field

[0001] This utility model relates to the field of mineral exploration technology, specifically to a device for collecting samples of altered surrounding rock. Background Technology

[0002] In the fields of geological exploration and mineral exploration, especially for unique and important deposit types such as breccia-type gold deposits, the study of wall rock alteration phenomena is of crucial guiding significance. These deposits are usually of considerable size (mainly medium to large) and have become an important part of gold resources both domestically and globally.

[0003] However, the breccia-type gold deposits discovered in China exhibit significant complexity and diversity in terms of ore genesis, ore-forming material sources, and wall rock alteration characteristics. Genetically, they encompass various types, including those associated with small intrusive bodies, porphyry systems, volcanic-subvolcanic activity, and unconformities / sedimentary discontinuities. Taking the typical Qiyugou area as an example, two major categories of breccia-type gold deposits—"gold deposits associated with porphyry systems" and "gold deposits associated with volcanic-subvolcanic rocks"—coexist in the same region, spatially closely associated with altered rock deposits, making them of immense research value. In recent years, with in-depth exploration (such as the new discoveries of the Qiyugou J4 and 189 granite bodies, the J46 porphyry body, the J8 breccia, and its surrounding areas), extensive and intense alteration and mineralization have been discovered within the breccia bodies and their surrounding wall rocks, clearly revealing a close intrinsic connection between breccia mineralization and wall rock alteration in terms of time, space, and material source.

[0004] In the study of the relationship between alteration and mineralization of the surrounding rocks of breccia-type gold ore bodies in the Qiyugou mining area, especially in the field specimen collection stage, traditional specimen collection methods (such as using cloth bags, ordinary plastic boxes, or simple separators) have high risks of specimen mixing and information distortion. At the same exploration point or adjacent area, it is often necessary to collect a series of specimens with different alteration types, different alteration intensities, and even different spatial locations (such as inside the breccia body, contact zone, and surrounding surrounding rocks). Traditional containers cannot achieve immediate and clear physical isolation of specimens on-site. Specimens are easily mixed and piled up, making it impossible to accurately correspond to the spatial location and geological background information of the original sampling point during subsequent laboratory analysis. This results in the loss or confusion of key geological information, seriously affecting the accuracy of alteration zoning maps and the reliability of alteration-mineralization relationship analysis. Furthermore, to distinguish specimens, geologists have to frequently change containers or manually sort, wrap, and label them on-site. This not only greatly slows down the progress of fieldwork but is also particularly inconvenient in complex mining environments (such as underground or steep slopes). Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a device for collecting alteration specimens of surrounding rocks. This device can collect multiple different alteration specimens of surrounding rocks at one time and store them separately, achieving immediate and clear physical isolation of the specimens. This avoids experimental analysis errors caused by specimen mixing and compression, and improves the accuracy of subsequent alteration zoning map compilation and the reliability of alteration-mineralization relationship analysis. This device can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for collecting samples of altered surrounding rock, comprising a collection box, wherein the collection box is provided with several horizontally and vertically intersecting partitions, the partitions dividing the interior of the collection box into multiple temporary storage areas, and two hinge plates are symmetrically hinged on the inner surface of each temporary storage area, and a torsion spring is provided at the hinge joint of the two hinge plates to keep the hinge plates horizontal, the hinge plates dividing the temporary storage area into a lower temporary storage area and an upper temporary storage area, and the upper side of the hinge plate will rotate downward to open the lower temporary storage area when pressure is applied.

[0007] As a preferred embodiment of this utility model, a limiting plate is fixedly provided on the inner surface of the temporary storage area, and the limiting plate is located on the upper side of the hinge plate.

[0008] As a preferred embodiment of this utility model, a cover plate is hinged to one side of the outer surface of the collection box, and a buckle matching the cover plate is hinged to the other side of the outer surface of the collection box. The buckle has an L-shaped cross-section. After the cover plate is placed on the collection box, the movable end of the cover plate can be fastened by rotating the buckle.

[0009] As a preferred embodiment of this utility model, a pad is provided inside the collection box, and the pad is positioned above the hinge plate.

[0010] As a preferred embodiment of this utility model, a slot is provided in the middle of the upper surface of the partition, and a corresponding card plate is fixedly provided between adjacent pads.

[0011] As a preferred embodiment of this utility model, the side surface of the card plate is provided with through holes.

[0012] As a preferred embodiment of this utility model, the outer side of the collection box is symmetrically provided with two shoulder straps.

[0013] As a preferred embodiment of this utility model, wheel frames are provided at the four corners of the lower surface of the collection box, and omnidirectional wheels and foot brakes are respectively provided on the wheel frames.

[0014] As a preferred embodiment of this utility model, a pull rod is hinged to the outer surface of the collection box.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: By setting multiple independent lower and upper temporary storage areas within the collection box, multiple alteration specimens of different surrounding rocks can be collected at once and temporarily stored separately, achieving immediate and clear physical isolation of the specimens. This avoids experimental analysis errors caused by specimen mixing and compression, improving the accuracy of subsequent alteration zoning map compilation and the reliability of alteration-mineralization relationship analysis. Simultaneously, multiple temporary storage areas allow for rapid specimen differentiation, significantly improving work efficiency. The lower and upper temporary storage areas are separated by a hinged plate. Initially, specimens can be directly placed into the collection box. Under the pressure of gravity, the specimens automatically fall into the lower temporary storage area. Subsequently, the hinged plate returns to a horizontal position under the elastic force of a torsion spring, without affecting the placement of subsequently collected specimens in the upper temporary storage area. This process requires no manual intervention for sorting or operation of the separating device, achieving automatic and orderly layered temporary storage of specimens in the vertical direction.

[0022] 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.

[0023] Example 1, please refer to Figures 1-3This utility model provides a technical solution: a device for collecting alteration specimens of surrounding rocks, including a collection box 1 for placing alteration specimens of surrounding rocks. The collection box 1 is provided with several horizontal and vertically intersecting partitions 2. The partitions 2 divide the interior of the collection box 1 into multiple temporary storage areas, which can collect multiple different alteration specimens of surrounding rocks at one time and store them separately. This achieves immediate and clear physical isolation of the specimens, avoids experimental analysis errors caused by specimen mixing and compression, and improves the accuracy of subsequent alteration zoning map compilation and the reliability of alteration-mineralization relationship analysis.

[0024] Each temporary storage area has two hinged plates 3 symmetrically hinged on its inner surface. The hinge joint of the two hinge plates 3 is equipped with a torsion spring to keep the hinge plates 3 horizontal. The hinge plates 3 divide the temporary storage area into a lower temporary storage area 4 and an upper temporary storage area 6. When pressure is applied to the upper side of the hinge plate 3, it will rotate downwards to open the lower temporary storage area 4. By separating the lower temporary storage area 4 and the upper temporary storage area 6 through the hinge plates 3, specimens can be directly placed into the collection box 1 at the initial stage of collection. Under the action of gravity, the specimens exert pressure on the hinge plates 3 (if the specimens are light, pressure can be applied manually to open the hinge plates 3), and they will automatically fall into the lower temporary storage area 4. A cushioning rubber pad or similar material can be placed on the bottom plate of the temporary storage area 4 to prevent damage to the specimens. Afterwards, the hinge plates 3 return to a horizontal position under the elastic force of the torsion springs, without affecting the placement of subsequently collected specimens into the upper temporary storage area 6. This process requires no manual intervention for sorting or operation of the separating device, achieving automatic and orderly layered temporary storage of specimens in the vertical direction.

[0025] The independent and layered temporary storage area design significantly reduces the collision and stacking compression of specimens during transportation within the box.

[0026] In a preferred embodiment, a limiting plate 5 is fixedly installed on the inner surface of the temporary storage area. The limiting plate 5 is positioned above the hinge plate 3, providing a precise mechanical stop for the upward rotation of the hinge plate 3 under the action of the torsion spring. In complex field environments (such as bumpy transportation or rapid operation), relying solely on the torsion spring may not guarantee that the hinge plate 3 will always perfectly return to a precise horizontal position. Slight tilting or misalignment can affect the stability of specimens subsequently placed in the upper temporary storage area 6, and may even pose a risk of accidentally opening the lower layer. The limiting plate 5 forcibly ensures that the hinge plate 3 is stably positioned in a precise horizontal position after repositioning, providing an absolutely flat and stable support platform for the upper specimen (upper temporary storage area 6). This greatly improves the operational reliability and safety of the device, avoiding specimen instability or accidental falling due to incomplete repositioning of the hinge plate.

[0027] In a preferred embodiment, a cover plate 7 is hinged to one side of the outer surface of the collection box 1. The cover plate 7 is used to close the collection box 1, isolate it from the external environment, and protect the specimen from damage.

[0028] The other side of the outer surface of the collection box 1 is hinged with a buckle 8 that matches the cover plate 7. The buckle 8 has an L-shaped cross-section. After the cover plate 7 is placed on the collection box 1, the movable end of the cover plate 7 can be fastened by rotating the buckle 8. The L-shaped buckle 8 can effectively resist vibration and impact during transportation, firmly lock the collection box 1, and ensure that the specimens stored in the box are absolutely safe during transportation, without displacement, loss or external contamination, thus ensuring the integrity and research value of the samples.

[0029] Meanwhile, the hinged cover and rotating L-shaped latch design enable quick one-handed opening and closing. Simply rotating the L-shaped latch 8 unlocks or locks the lid, making the operation intuitive, fast, and effortless, without the need for tools. The opening and closing action of the hinged cover 7 is also natural and smooth. This greatly improves field sampling efficiency, reduces operational complexity, and perfectly adapts to the fast-paced, multi-point sampling needs of breccia mining areas.

[0030] In a preferred embodiment, the collection box 1 is equipped with a pad 9, which is positioned above the hinge plate 3. The lower surface of the pad 9 has grooves on both sides corresponding to the limiting plate 5. After placing a specimen in the lower temporary storage area 4, the pad 9 can be placed above the hinge plate 3 and supported by the limiting plate 5, thus forming a more stable base plate for the upper temporary storage area 6, capable of holding heavier specimens.

[0031] In a preferred embodiment, a slot 10 is provided in the middle of the upper surface of the partition 2. A corresponding locking plate 11 is fixedly installed between adjacent pads 9. Multiple locking plates 11 can connect all pads 9 into a single unit, facilitating simultaneous retrieval of the upper specimen and opening of the lower temporary storage area 4. This makes specimen placement and retrieval more convenient and further improves work efficiency. Initially, the locking plates 11 and pads 9 can be removed, and the collected sample placed into the lower temporary storage area 4. After the lower temporary storage area 4 is full, the pads 9 are placed into the collection box 1 using the locking plates 11, which then engage with the corresponding slots 10, forming a stable base for the upper temporary storage area 6.

[0032] A further preferred technical solution is that a through hole 12 is provided on the side surface of the middle card plate 11. The through hole 12 is located at the top, which makes it convenient for workers to lift and remove the card plate 11 and the pad plate 9 by passing their fingers or other tools such as ropes or hooks through the through hole 12. The operation is simple and convenient.

[0033] Example 2, please refer to Figure 4 This embodiment is largely the same as Embodiment 1, except that: two shoulder straps 13 are symmetrically arranged on the outside of the collection box 1, so that staff can carry the collection box 1 and the collected samples, etc.

[0034] Example 3, please refer toFigure 5 This embodiment is largely the same as Embodiment 1, except that: wheel frames 14 are provided at the four corners of the lower surface of the collection box 1, and casters 15 and foot brakes 16 are provided on the casters 14 respectively. The collection box 1 can be moved or parked conveniently by the casters 15 and foot brakes 16. This embodiment can be used when using a larger collection box to sample in a relatively flat area of ​​the mining area, so as to facilitate sampling and reduce the labor intensity of the staff.

[0035] Preferably, a pull rod 17 is hinged to the outer surface of the data collection box 1. The pull rod 17 can be a telescopic pull rod. The pull rod 17 is hinged so that it can be opened when the data collection box 1 needs to be moved, and the data collection box 1 can be moved by pulling the data collection box 1 via the casters 15; when the data collection box 1 is parked, the pull rod 17 can be lowered and hang down close to the box body, which can reduce the space occupied.

[0036] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
