Description

Technical Field

[0001] The invention relates to the technical field of mining engineering, in particular to a demonstration model for the movement law of ore-discharging bulk. Background Art

[0002] Loose ore usually refers to the scattering and movement of ore or mineral particles in simulated or actual operations in mining, geological exploration or related experiments. This operation involves transferring minerals from one location to another, usually for processing, screening, classification or further simulation, experiment and analysis; in a laboratory simulation environment, loose ore may involve the use of mineral simulation materials of different particle sizes and types, such as glass particles or pebbles of different colors or demonstration models made of controllable color-changing materials, to simulate the movement, accumulation and stratigraphic distribution of real ores in nature. This type of simulation can help scientists, engineers, students, etc. to understand the morphology of minerals under various natural and artificial influences and the simulated state of ore release, as well as how to more effectively mine and manage mineral resources; in the mining industry, the actual operation of loose ore may include transportation from the mining point to the processing plant, or movement within the mining site, etc., which usually involves a large number of mechanical equipment and transportation systems. These operations are crucial to the economic efficiency and environmental safety of the mining industry, so we propose this experimental invention to simulate ore release before actual operation, thereby indirectly ensuring the safety and feasibility of actual operation.

[0003] According to the announcement number CN111882973A, a demonstration model of the movement law of scattered ore-releasing bodies is disclosed, which relates to the field of mining engineering technology. The main structure includes a box shell, a scattered body and a plurality of partitions; the plurality of partitions are arranged in the box shell and divide the interior of the box shell into a plurality of independent spaces; the scattered body is arranged in the plurality of independent spaces; the model is made by a controllable color-changing material, and the law of movement of the scattered body can be intuitively seen on the model, and a rough curve of the movement of the scattered body can be depicted; each experiment is short in time and effective quickly, and the ore-releasing materials can be quickly reused, and the materials for simulating ore-releasing can be processed in a short time after ore-releasing to conduct a secondary experiment; according to the demonstration, the simulated ore-releasing materials can be designed in proportion to simulate the underground mine. Rock ore laying, supplement its theory, provide intuitive data for related teaching and trial experiments, provide more theoretical parameters for underground operations, and thus help reduce the occurrence of underground accidents. In the current simulation system, although it is designed to simulate the distribution and behavior of loose ore, there are some obvious limitations, especially in terms of flexibility and adaptability; first, the system cannot flexibly adjust the position of lights and partitions according to specific simulation needs, which is particularly restrictive when trying to reproduce the distribution of loose ore under different geological and environmental conditions; in the real world, mineral distribution is affected by many factors, including light, pressure and stratum structure, so this defect of the simulation equipment may lead to the inability to accurately reproduce some key natural processes;

[0004] In addition, another key limitation lies in the design of its discharge port valves. During the simulation process, different ore distribution and flow patterns may require different numbers and configurations of discharge ports to adapt to different experimental scenarios. However, the system requires that each different number of discharge port valves must be individually manufactured to meet the needs. This not only increases the cost and complexity of the equipment, but also greatly limits its application flexibility under variable experimental conditions. Since the number and location of the discharge ports cannot be adjusted in real time, this design defect becomes a significant bottleneck when it is necessary to quickly adapt to new experimental conditions.

[0005] In summary, although the simulation system provides effective simulation functions in some aspects, it has certain limitations in adapting to complex and changing simulation needs; these limitations may affect the accuracy of the simulation and the wide application of the experiment, especially in the accurate simulation of the distribution and behavior of mineral bulk. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a demonstration model for the movement rules of loose ore, which solves the problems of complex installation and operation of traditional demonstration models, non-reusable equipment, non-intuitive simulation process, difficult layered processing, inflexible equipment adjustment, inability to simulate mines with different inclinations and poor environmental protection.

[0007] To achieve the above purpose, the present invention is implemented by the following technical scheme: a demonstration model of the movement law of ore-discharging bulk, including a metal frame, a feed frame is fixedly connected to the bottom of the metal frame, a rotating shaft is fixedly connected to the middle of the metal frame, and the rotating shaft is connected to the two sides of the middle of the storage frame, which is used to allow the storage frame to rotate in the metal frame, so as to obtain the mine inclination angle simulated by the experiment. A light shield is provided on one side of the storage frame, a purple light board is connected to the bottom of the light shield, and the purple light board and the light shield are arranged on the same side of the storage frame, a docking plate is rotatably connected inside the storage frame, a screw 1 is threadedly connected inside the docking plate, and a rubber pad is fixedly connected to one end of the screw 1, a plug-in frame is fixedly connected to one side of the storage frame, and one side of the light shield and the purple light board are both slidably connected inside the plug-in frame, a discharge bottom frame is provided at the bottom of the storage frame, a discharge port is provided inside the discharge bottom frame, and a split component is provided on one side of the discharge bottom frame.

[0008] Preferably, the splitting assembly includes a docking block 1, the docking block 1 is fixedly connected to one side of the discharge bottom frame, a rotating column is rotatably connected between the docking blocks 1, and a pressure plate is fixedly connected to the outer wall of the rotating column.

[0009] Preferably, one side of the pressure plate is fixedly connected to a docking block 2, one side of the docking block 2 is provided with a plurality of rubber balls, and the rubber balls are fixedly connected to the material storage frame.

[0010] Preferably, the pressure plate is internally threadedly connected with a second screw, and one end of the second screw passes through the pressure plate and is threadedly connected to the inside of the material storage frame.

[0011] Preferably, a docking frame is fixedly connected to the top of the discharging bottom frame, and the docking frame can be slid up and down with the discharging bottom frame and connected to the bottom of the storage frame, which is used to facilitate the processing of materials in the tank after the simulation experiment.

[0012] Preferably, a plurality of equidistant ore-discharging openings are provided with manually adjustable switch valves for simulating the states before and after the ore-discharging holes are opened.

[0013] Working principle: When demonstrating the movement law of loose ore discharge, the screw can be turned according to the needs to drive the rubber pad to move through the thread, so that the rubber pad can realize the fixed state and the unfixed state of the light baffle or the ultraviolet light board, and then the light baffle and the ultraviolet light board can be freely replaced and placed in the interlayer to achieve the desired simulation effect. When the rubber pad is in an unfixed state, the light baffle and the ultraviolet light board can be fixed to the storage frame and not easy to fall through the existence of the plug-in frame, and then the light baffle and the ultraviolet light board can be slowly inserted and pulled according to the needs. When the corresponding simulation operation is performed, the experimental materials such as color-changing glass are used to simulate the loose ore, and they are laid into the feeding frame in sequence according to the interlayer of the feeding frame. Through the cooperation of the light baffle and the ultraviolet light board, the color-changing glass and other materials are layered to simulate the actual situation of the mine, and then the switch valve is opened to allow the experimental materials simulating the loose ore to fall into the designed feeding frame through the position of the ore discharge port, so as to realize the movement observation simulation of the loose ore. When different numbers of ore-releasing openings are required, the position of the pressure plate can be no longer fixed by turning screw 2, and then the pressure plate can be pulled to rotate with the rotating column as the center through a certain force, and then the rubber ball can be driven to separate from the position of the storage frame through docking block 2. At this time, pulling the discharge bottom frame can allow the discharge bottom frame to drive the docking frame to separate from the storage frame for replacement, so as to replace the discharge bottom frame with different numbers of ore-releasing openings.

[0014] The present invention provides a demonstration model of the movement law of loose ore discharge. It has the following beneficial effects:

[0015] 1. The present invention realizes the effect of freely disassembling the light baffle and the ultraviolet light board in order through the cooperation between the feeding frame, screw one and rubber pad and other components. This design greatly enhances the adaptability of the experiment, allowing the distribution level of the mineral bulk to be quickly adjusted according to different research needs to accurately simulate various geological accumulation environments. In addition, by turning the screw one to move the rubber pad, the light baffle and the ultraviolet light board can be easily installed and removed, thereby providing an efficient and repeatable experimental setting method and enhancing the flexibility and accuracy of the experimental process.

[0016] 2. The present invention uses the connection of the rotating shaft to allow the material storage frame to adjust the required angle in the metal frame, which is convenient for simulating the required mine inclination, so that the simulated experiment is more in line with the real ore-feeding effect, and a more realistic simulated ore-feeding state is obtained.

[0017] 3. The present invention realizes the free disassembly and replacement of the discharge bottom frame through the cooperation between the rubber ball, the docking block 2 and the screw 2. This design allows the equipment to easily adapt to different simulation requirements of the movement of loose ore. The output rate and distribution of the loose ore can be adjusted by replacing the discharge bottom frame with different numbers of ore discharge ports. This not only improves the applicability and flexibility of the equipment, but also enables any adjustments during the experiment to quickly and accurately reflect the needs of dynamic changes in the loose ore.

[0025] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a demonstration model of the movement law of loose ore, including a metal frame 1, a feeding frame 2 is fixedly connected to the bottom of the metal frame 1, a rotating shaft 20 is fixedly connected to the middle of the metal frame 1, and the rotating shaft 20 is connected to both sides of the middle of the storage frame 3, which is used to allow the storage frame 3 to rotate in the metal frame 1, so as to obtain the simulated mine inclination required for the experiment. A light baffle 4 is provided on one side of the material storage frame 3, and a purple light board 5 is connected to the bottom of the light baffle 4. The purple light board 5 and the light baffle 4 are arranged on the same side of the material storage frame 3. A docking plate 6 is rotatably connected inside the material storage frame 3, and a screw 8 is threadedly connected inside the docking plate 6. A rubber pad 9 is fixedly connected to one end of the screw 8. An insertion frame 7 is fixedly connected to one side of the material storage frame 3. One side of the light baffle 4 and the purple light board 5 are both slidably connected inside the insertion frame 7. A discharge bottom frame 10 is provided at the bottom of the material storage frame 3, and a mine discharge port 11 is opened inside the discharge bottom frame 10. A split component is provided on one side of the discharge bottom frame 10, and multiple equidistant mine discharge ports 11 are provided with manually adjustable switch valves 12, which are used to simulate the states before and after the mine discharge hole is opened.

[0028] Specifically, in the simulation demonstration of the movement law of loose mineral bodies, the design of the experimental device allows the position and state of internal components to be adjusted through precise mechanical operations. The specific operation is to turn screw 8, which can drive the rubber pad 9 below to move along the set path. This displacement mechanism is not only precise but also reversible, allowing the rubber pad 9 to switch between fixed and non-fixed states, thereby controlling the installation and removal of the light baffle 4 and the ultraviolet light board 5; when the rubber pad 9 is in a non-fixed state, the light baffle 4 and the ultraviolet light board 5 can be freely replaced. This process can be carried out smoothly, partly due to the design of the plug-in frame 7, which ensures that these panels will not fall off accidentally even in a non-fixed state. In addition, the user can slowly insert and remove the light baffle 4 and the ultraviolet light board 5 according to experimental needs to adjust the internal structure of the experimental device. ; In the simulation experiment, photochromic glass is used to simulate loose minerals. According to the specific requirements of the experiment, these glass particles will be laid out in sequence and placed in the interlayer of the feed frame 2. The correct configuration and coordination of the light-blocking plate 4 and the ultraviolet light board 5 make these photochromic glass particles form a clear layered effect visually, further simulating the layered structure of mineral particles in the natural accumulation process; finally, when the experiment is ready, by opening the switch valve 12, the photochromic glass simulating loose minerals will fall into the feed frame 2 through the position of the ore discharge port 11, thereby realizing the dynamic movement of the loose minerals in the simulated environment. The rotating shaft 20 is fixed between the metal frame 1 and the storage frame 3 based on the stability considerations when adjusting the angle of the storage frame 3. Based on the stability considerations when adjusting the angle of the storage frame 3, the rotating shaft 20 is arranged to be connected to the center horizontal line of the storage frame 3 and is connected to the metal frame 1.

[0029] Please see attached Figure 5 -Attached Figure 6The disassembly component includes a docking block 14, which is fixedly connected to one side of the discharge bottom frame 10, and a rotating column 15 is rotatably connected between the docking blocks 14. A pressing plate 16 is fixedly connected to the outer wall of the rotating column 15, and a docking block 2 17 is fixedly connected to one side of the pressing plate 16. A plurality of rubber balls 18 are arranged on one side of the docking block 2 17, and the rubber ball 18 is fixedly connected to the storage frame 3. A screw 2 19 is threadedly connected to the inside of the pressure plate 16, and one end of the screw 2 19 passes through the pressure plate 16 and is threadedly connected to the inside of the storage frame 3. A docking frame 13 is fixedly connected to the top of the discharge bottom frame 10, and the docking frame 13 can be slid up and down with the discharge bottom frame 10 and connected to the bottom of the storage frame 3, which is used for simulating experiments to facilitate the processing of materials in the tank.

[0030] Specifically, in the design of the experimental device, the modular characteristics of the discharge bottom frame 10 allow the user to flexibly adjust the number of ore discharge ports 11 according to the needs of the experiment. This adjustment mechanism is achieved through fine mechanical operation, ensuring the adaptability and accuracy of the experiment. First, the user needs to operate screw 2 19 to release the fixed state of the pressure plate 16. Screw 2 19 is equipped with precision threads, which can accurately control the displacement of the pressure plate 16. This is the first step in the adjustment process. Subsequently, the user needs to apply a certain force to the pressure plate 16 to rotate it around the rotating column 15. When the pressure plate 16 rotates into place, it drives the rubber ball 18 out of the initial position of the storage frame 3 through the driving action of the docking block 2 17. ; Next, the user pulls the discharge bottom frame 10, which drives the docking frame 13 to separate from the storage frame 3. This separation is smooth and precise, ensuring that the discharge bottom frame 10 can be safely removed and replaced. At this time, according to the needs of the experimental design, the discharge bottom frame 10 with different numbers of ore discharge ports 11 can be selected for replacement to adapt to different experimental conditions and research purposes. This design not only enhances the flexibility and applicability of the device, but also ensures the safety and repeatability of the operation, making the experimental process more stable and reliable. Through these fine mechanical adjustments, the experimenter can accurately control the distribution and movement of the ore bulk, so as to study its behavior and laws under different conditions.
