Description

Technical Field

[0001] This utility model relates to the field of rock and mineral sampling technology, specifically a rock and mineral sampling and composition identification device for geological research. Background Technology

[0002] As is well known, my country's geological structure is complex and diverse, with abundant mineral content. To obtain the mineral content of rocks and minerals, current rock and mineral sampling devices mainly involve using geological hammers to break off rock blocks or using power tools to obtain rock blocks as samples. Due to wind, rain, or acid rain corrosion on the rock surface, the sample composition is not ideal. The obtained rock samples are then transported to the laboratory using ordinary containers, and then the rock sample specimens are pulverized to obtain powder of about 50 mesh. In order to accurately detect the composition of rock minerals, it is necessary to analyze them using common laboratory instruments such as X-ray fluorescence, atomic absorption, MS, and M6 to analyze their mineral composition, content, particle size, structure, and secondary changes, so as to obtain more accurate data. The above-mentioned rock sample containers are not only used in large quantities, which easily contaminates the samples, but also the information labeling is prone to confusion. The process of bringing the samples back to the laboratory is also relatively long, and the rock sample pulverizing equipment used later is also prone to contaminating the rock samples.

[0003] According to the novel structure search report, announcement number CN205580776U discloses a special rock and mineral sampling and composition identification device for geological research. The sampling device is composed of an electric hammer, a sampling drill bit, a sieve cylinder, a rock sample box, and a rock container. The device obtains rock sample data through sampling, preparation and sieving, obtaining rock powder, sealing the rock column, labeling sample information, multi-point sampling, and laboratory analysis. It utilizes a specially designed sampling drill bit structure, which can not only obtain rock columns and rock powder that meets the composition identification requirements in one go, but also avoids rock sample contamination when using the rock sample box on site.

[0004] The aforementioned technology discloses a geological research-specific rock and mineral sampling and composition identification device, which facilitates the direct acquisition of rock sample powder during sampling and avoids rock sample contamination through the rock sample box used on-site. However, it still has the following shortcomings in use:

[0005] After drilling and grinding to form rock powder, the current method requires separately removing the sampling drill bit and then pouring the rock powder into a screening cylinder for sieving. This makes it difficult to determine whether the grinding area has been reached and rock powder has been generated after drilling and sampling. It is not feasible to directly discharge the fragments and collect the rock powder by vibration screening during drilling and sampling. The method of repeatedly pulling out the drill bit for observation and pouring it out for separate screening is not ideal in terms of convenience and lacks the process of vibration with the help of the screen, resulting in unsatisfactory screening effect. In view of this, this application proposes a special rock and mineral sampling and composition identification device for geological research to solve the above-mentioned problems.

[0029] 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.

[0030] like Figures 1 to 3 As shown in this embodiment, a geological research-specific rock and mineral sampling and composition identification device includes an impact drill 1 and a rock and mineral drilling and grinding sampling and screening collection mechanism connected to its clamping head. The rock and mineral drilling and grinding sampling and screening collection mechanism includes:

[0031] The drill bit shank 101 is clamped inside the chuck of the impact drill 1;

[0032] Rotary sleeve 2 is fixedly installed with drill bit shank 101. Its left side is set as an opening, and its inner side is set as a tapered structure with the left side smaller and the right side larger. The bottom inner wall, top inner wall, front inner wall and rear inner wall of the rotary sleeve 2 are all provided with debris discharge holes 204. The drill bit shank 101 is used to drive the rotary sleeve 2 to rotate when the impact drill 1 is started.

[0033] The locking assembly is fixedly connected to the left side of the rotating sleeve 2;

[0034] The sampling drill bit 3 is mounted on the clamping and locking assembly; the clamping and locking assembly is used to clamp, position and lock the sampling drill bit 3, and to drive the sampling drill bit 3 to rotate for rock and mineral drilling and sampling when the rotating sleeve 2 rotates.

[0035] Support 6 is fixedly connected to the inner wall of the right side of the rotating sleeve 2 and located inside the sampling drill bit 3. Multiple grinding teeth 601 are fixedly connected to the left side of support 6. Support 6 is used to drive multiple grinding teeth 601 to rotate when the rotating sleeve 2 rotates. During the drilling and sampling process, when the core is inside the sampling drill bit 3 and squeezed with the grinding teeth 601, the core does not rotate because the end of the core is still located at the rock and mineral hammer end. The rotating grinding teeth 601 directly grind and crush the front end of the core to obtain a crushed sample that can be collected and analyzed by personnel.

[0036] The slag discharge assembly is installed on the outside of the rotating sleeve 2; the slag discharge assembly is used to guide the crushed material sample outward.

[0037] The sieving and collecting component is threadedly sleeved on the slag discharge component; the sieving and collecting component is used for sieving and collecting fragmented samples that are discharged outwards.

[0038] Specifically, the locking assembly includes a positioning sleeve 201 fixedly connected to the left side of the rotating sleeve 2. The positioning sleeve 201 is movably fitted inside the sampling drill bit 3. Two locking posts 203, both located inside the positioning sleeve 201, are fixedly connected to the left side of the rotating sleeve 2. The sampling drill bit 3 is movably locked onto the two locking posts 203. The top and bottom right sides of the sampling drill bit 3 are provided with locking grooves, which are movably locked onto the corresponding locking posts 203. The top of the sampling drill bit 3 is pressed tightly against a T-shaped clamping screw 202, and the positioning sleeve 201 is threaded onto the T-shaped clamping screw 202. On the screw 202, the top of the positioning sleeve 201 is provided with a threaded hole that is threaded to the T-shaped clamping screw 202. The positioning sleeve 201, the locking pins 203 and the T-shaped clamping screw 202 cooperate to insert the sampling drill bit 3 into the positioning sleeve 201 to the right. The sampling drill bit 3 is clamped to the right on the two locking pins 203. The two locking pins 203 and the positioning sleeve 201 are used to clamp and position the sampling drill bit 3. The T-shaped clamping screw 202 is rotated in the forward direction to make it press down on the sampling drill bit 3, thereby achieving the effect of clamping, positioning and locking the sampling drill bit 3.

[0039] Furthermore, the slag discharge assembly includes two sealed bearings fixedly sleeved on the outside of the rotating sleeve 2. The four slag discharge holes 204 are all located between the two sealed bearings. The same support sleeve 4 is fixedly sleeved on the outer side of the outer ring of the two sealed bearings. The bottom of the support sleeve 4 is connected to and fixedly connected to an external threaded slag discharge sleeve 401 located between the two sealed bearings. The sealed bearings, support sleeve 4 and external threaded slag discharge sleeve 401 cooperate to block the slag discharged through the four slag discharge holes 204 on both sides, so that the slag can only be discharged downward through the external threaded slag discharge sleeve 401. The sealed bearings also serve to rotate the support sleeve 4, making it easy for personnel to keep the support sleeve 4 from rotating with the rotating sleeve 2.

[0040] Furthermore, the screening and sampling assembly includes an internally threaded sleeve 5 that is threaded onto the outside of the externally threaded slag discharge sleeve 401. The bottom of the internally threaded sleeve 5 is connected to and fixedly fitted with a circular box 501 with an open bottom. A screen 502 is fixedly connected inside the circular box 501. An external thread is formed on the bottom outer side of the circular box 501, and a transparent sampling box 503 is threadedly fitted onto it. The upper inner side of the transparent sampling box 503 has an internal thread that meshes with the external thread, and a threaded cap 504 is fitted to match the internal thread. The internally threaded sleeve 5, the circular box 501, the screen 502, and the transparent sampling box 503 work together to utilize the internally threaded sleeve 5 to secure the externally threaded slag discharge sleeve 401. The discharged slag is guided into the round box 501. When the impact drill 1 is running and vibrating, it also drives the screen 502 to vibrate in sequence through the drill bit shank 101, rotating sleeve 2, sealed bearing, support sleeve 4, external threaded slag discharge sleeve 401, internal threaded sleeve 5 and round box 501. The vibration of the screen 502 is used to achieve the vibration screening of the slag. The screened slag powder is collected by the transparent sample collection box 503. Personnel can easily and intuitively know whether the powder sample has been successfully collected by observing the transparent sample collection box 503. After collection, the transparent sample collection box 503 is reversed and removed, and the threaded cap 504 is screwed into the inside of its top to seal it.

[0041] Combined with appendix Figures 1-3 The specific operating steps for the geological research-specific rock and mineral sampling and composition identification device are as follows:

[0042] S1: Sampling:

[0043] The drill bit shank 101 is installed in the chuck of the impact drill 1. The impact drill 1 drives the rotating sleeve 2 to rotate through the drill bit shank 101. With the support of the rotating sleeve 4 by the sealed bearing, the operator can hold the sleeve 4 with one hand to keep it from rotating. The rotating sleeve 2 drives the sampling drill bit 3 to rotate through the two clasps 203. The sampling drill bit 3 drills and samples the rock and ore. When the rotating sleeve 2 rotates, it also drives multiple grinding teeth 601 to rotate through the support 6. During the drilling and sampling process, when the rock core is inside the sampling drill bit 3 and squeezes against the grinding teeth 601, the rock core does not rotate because the end of the rock core is still at the rock and ore hammer end. The rotating grinding teeth 601 directly grind and crush the front end of the rock core to form crushed material. The crushed material enters the rotating sleeve 2 and is thrown out into the support sleeve 4 through the four slag discharge holes 204. The two sealed bearings on both sides block the slag discharged through the four slag discharge holes 204, so that the slag can only be discharged downward through the external threaded slag discharge sleeve 401.

[0044] S2: Screening:

[0045] The internal threaded sleeve 5 directly guides the slag discharged from the external threaded slag discharge sleeve 401 into the round box 501. When the impact drill 1 vibrates, it also drives the screen 502 to vibrate in sequence through the drill bit shank 101, rotating sleeve 2, sealed bearing, support sleeve 4, external threaded slag discharge sleeve 401, internal threaded sleeve 5, and round box 501. The vibration of the screen 502 realizes the vibration screening of the slag. The transparent sample collection box 503 is used to collect the screened slag powder. Personnel can easily and intuitively observe the transparent sample collection box 503. After confirming whether the powder sample has been successfully collected, the transparent sample collection box 503 can be reversed and removed, and the threaded cap 504 can be screwed into the inside of its top to seal it. This allows the crushed material to be discharged directly during drilling and sampling, and the rock powder can be collected by integrated vibration screening. This makes it convenient for personnel to directly observe whether the powder sample has been successfully collected by looking at the transparent sample collection box 503, without having to pull it out for observation, thus improving ease of use. Furthermore, the vibration force of the impact drill 1 is used to form an integrated vibration screening method, which improves the screening effect.

[0046] S3: When taking subsequent rock column samples, after pulling out the sampling drill bit 3, break the rock column formed by drilling by simple knocking, then take it out from the borehole and put it into the external rock container for later use. Then, attach labels to the corresponding rock container and transparent sample collection box 503. The labels should indicate the collection location, the name of the collector, the time, and other information.

[0047] S4: Multi-point sampling:

[0048] Depending on the purpose of the sampling, whether it is single-point sampling, linear sampling along the vein, or large-area sampling, the aforementioned steps can be used to obtain multiple samples.

[0049] S5: Laboratory Analysis:

[0050] All acquired samples were sent to the laboratory for analysis, including X-ray fluorescence, atomic absorption, MS, or M6 instruments. Based on the analysis results, the mineral composition and symbiotic assemblage, ore structure, secondary mineral alterations and their contents were determined. Phase analysis was used to determine the degree of ore oxidation, classify ore types, and understand their distribution patterns. Mineral and ore type distribution maps of the deposit or ore body were then compiled.

[0051] The types and contents of various mineral components in the ore can be accurately statistically analyzed using the aforementioned multi-point sampling method, including point, line, and surface measurements. Then, based on the measured physical properties of the minerals, such as crystal shape, particle size, hardness, magnetism, and conductivity, the subsequent ore beneficiation and processing methods and reasonable technical indicators can be determined, providing reliable data for improving beneficiation recovery rate and comprehensive utilization of the ore.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
