Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ore body mining, and particularly relates to a tungsten ore mining and sorting collaborative device. BACKGROUND

[0002] Tungsten is an element widely distributed in various types of rocks, but its content is low, and it must be enriched through related geological processes to form a deposit and be mined as a commercial ore. Tungsten is a high-melting-point rare metal or refractory rare metal in the field of metallurgy and metal materials. Tungsten and its alloys are one of the most important functional materials in modern industry, national defense and high-tech applications, and are widely used in aerospace, atomic energy, shipbuilding, automobile industry, electrical industry, electronic industry and chemical industry and many other fields. The mining of tungsten ore usually needs to be combined with the beneficiation process to improve the ore grade and ensure the efficient use of tungsten ore resources.

[0003] However, the mining and sorting of tungsten ore are usually carried out separately. The mined ore needs to be transported first and then enters a special screening device for preliminary screening and grading treatment. This separate operation mode results in low efficiency of the whole process and cannot realize real-time screening during the mining process. Especially in underground mines, the existing mining method needs to transport the ore from underground to the ground and then screen it. This process not only has low efficiency, but also increases the transportation cost and equipment operation burden.

[0032] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] Please refer to Figures 1-8 The embodiment provides a tungsten ore mining and sorting device, which comprises a mining machine, the mining machine comprises a crushing bin 1, a moving assembly 2, a mining bucket 3 and a screening bin 4. The mining bucket 3 is located at the front side of the mining machine, so that the mined ore can smoothly enter the crushing bin 1 for preliminary crushing, and then enter the screening bin 4, without the need for additional conveying equipment, thereby improving the mining efficiency. The crushing bin 1 can be provided with a crushing roller, which facilitates subsequent screening after preliminary crushing. The crushing bin 1 adopts a detachable form. The moving assembly 2 comprises a base 21 and a roller 22. The base 21 provides stable structural support for the entire device, and the roller 22 enables the mining machine to move flexibly, thereby adapting to different mining sites and facilitating ore mining and transportation.

[0034] Referring to Figure 2 and Figure 3 , the screening bin 4 is fixed above the base 21, and the top opening of the screening bin 4 receives the tungsten ore mined from the mining bucket 3, and the screening bin 4 is the core screening part of the entire device, and the ore particle size is classified through multi-layer screening. The screening bin 4 is sequentially provided with a first screen 5, a second screen 6, a turnover plate 7 and a plurality of sorting hoppers 8 from top to bottom. The first screen 5 is uniformly provided with coarse holes 51, which are used to screen out larger particles of tungsten ore, so that smaller tungsten ore can continue to enter the second screen 6 for fine screening. The first screen 5 falls through vibration action, effectively separating tungsten ore of different particle sizes. The second screen 6 includes a vibration plate 61 and an extension plate 62. The vibration plate 61 is a hollow plate and is located on both sides of the screening bin 4. One end of the vibration plate 61 is hinged to the side wall of the screening bin 4 and has a certain degree of rotational freedom, and the other end is an opening. The vibration plate 61 provides the necessary vibration force in the screening process, so that the tungsten ore can smoothly pass through the second screen 6. The extension plate 62 can be accommodated in the vibration plate 61 or extended from the opening of the vibration plate 61. The extension plate 62 is uniformly provided with fine holes 63, which are mainly used to screen finer tungsten particles.

[0035] Referring to Figure 2 and Figure 4 , one end of the turnover plate 7 is movably connected to the bottom of the screening bin 4. The turnover plate 7 guides the tungsten ore screened through the first screen 5 and the second screen 6 into different sorting hoppers 8 through left and right turnover actions, ensuring that each sorting hopper 8 collects tungsten ore of different particle sizes, effectively improving the screening efficiency, reducing manual operation, and making the separation of tungsten ore more accurate.

[0036] Referring to Figure 5 , further, a plurality of nozzles 9 are arranged on the upper side of the first screen 5 and the second screen 6, respectively, and the nozzles 9 are fixed to the side wall of the screening bin 4. The nozzles 9 form an air curtain by spraying air flow, preventing fine ore dust from drifting during the screening process, reducing environmental pollution, and avoiding waste of ore resources. The design of the nozzles 9 not only plays an environmental protection role, but also can blow the ore through the air flow to help it pass through the screen faster and improve the screening efficiency.

[0037] Referring to Figure 3 and Figure 6, specifically, the nozzle 9 includes a horizontal air outlet 91 and an inclined air outlet 92, the horizontal air outlet 91 is mainly designed to form an air flow barrier to prevent fine particles and dust from drifting outside the screening bin 4 during the screening process, especially when screening tungsten ore, a large amount of powder will be generated, the air flow barrier can effectively prevent the escape of these dust and reduce environmental pollution. The design of the inclined air outlet 92 is more targeted, the inclined air outlet 92 is inclined downward, and the inner diameter becomes smaller along the air outlet direction. This tapered structure increases the speed of the airflow when passing through the inclined air outlet 92, which can effectively blow the larger particles of tungsten ore with greater impact force, making it pass through the screen smoothly, and also avoiding the clogging of the screen. The inclination angles of the plurality of inclined air outlets 92 on the upper side of the first screen 5 are different, and the airflow with different angles can ensure the uniform distribution of the ore on the screen and further promote the effective screening of the larger particles of ore.

[0038] An air tank 10 is arranged outside the upper side wall of the screening bin 4, the air tank 10 is in communication with the nozzle 9, and the air tank 10 can provide a stable and adjustable air flow source for the nozzle 9. By controlling the valve, the air flow of the nozzle 9 can be controlled according to the actual screening requirements to ensure that the screening effect of the ore on different screens reaches the best. The bottom of the screening bin 4 is a non-closed structure, and the air flow can finally flow out from the bottom of the screening bin 4.

[0039] The air tank 10 includes a plurality of air inlets 101, the air inlets 101 are in communication with an air pump 11 through an air inlet pipe 102, and the air pump 11 is fixed on a base 21 and located at the rear side of the mining machine. The air flow provided by the air pump 11 is delivered to the air tank 10 through the air inlet pipe 102, and then uniformly distributed to each nozzle 9 by the air tank 10. This design ensures that the nozzle 9 can continuously provide stable air flow during the screening process. The air pump 11 is located at the rear side of the mining machine, which avoids interference with other working parts and ensures stable and efficient air flow supply of the whole device.

[0040] Please refer to Figure 2 and Figure 7 , the first screen 5 is rectangular and matches the shape of the screening bin 4, and a first telescopic cylinder 52 is arranged on each of the four corners of the rectangle, the first telescopic cylinder 52 is fixed on the side wall of the screening bin 4, and the output end thereof is in contact with the bottom of the first screen 5. The function of the first telescopic cylinder 52 is to drive the first screen 5 to vibrate up and down through the telescopic action, so that the tungsten ore moves faster on the screen surface and passes through the screen hole. Especially when dealing with larger particles of ore, vibration can speed up the separation efficiency of the ore. This design avoids the accumulation of ore on the screen, improves the smoothness of screening, and reduces the possibility of clogging during the screening process.

[0041] The four first telescopic cylinders 52 can simultaneously perform telescopic movement at the beginning of screening to drive the whole vibration of the first screen 5. After a period of time, the four first telescopic cylinders 52 can perform telescopic operation in a preset order one by one. Through this alternating vibration mode, the vibration mode of the first screen 5 is more diversified, the screening effect is further optimized, the accumulation and blockage of ore particles can be avoided, and the screening efficiency of the first screen 5 on different particle size tungsten ores is improved.

[0042] Please refer to Figure 2 and Figure 8 The second screen 6 is arranged downwardly inclined. The inclined design enables the smaller particle tungsten ore to smoothly slide downward under the action of gravity, and then enters the sorting hopper 8 after further screening. The side wall of the screening bin 4 is fixed with a second telescopic cylinder 64. The output end of the second telescopic cylinder 64 is in contact with the bottom of the vibration plate 61. The second telescopic cylinder 64 drives the second screen 6 to vibrate up and down through the telescopic action.

[0043] The first telescopic cylinder 52 and the second telescopic cylinder 64 are both driven by motors. These high-frequency working motors generate a large amount of heat during operation. In order to ensure that the motors can maintain normal working temperature during long-time operation, the heat generating parts of these motors are connected to the air tank 10 through heat dissipation pipes. The air flowing in the air tank 10 can effectively dissipate heat for the motors, and the heat generated by the motors is taken away by the air flow, so as to maintain the continuous and stable operation of the equipment.

[0044] The telescopic plate 62 is fixedly arranged at the end outside the vibration plate 61. The air bag 65 is arranged at the end of the telescopic plate 62. The air bag 65 is a closed structure, and is filled with gas. When the telescopic plates 62 on both sides are extended from the opening of the vibration plate 61, the air bag 65 closes the gap between the two telescopic plates 62 by contact and extrusion, preventing ore or dust from overflowing from the gap, and ensuring the screening effect. When the telescopic plate 62 is stored in the vibration plate 61, the air bags 65 on both sides also close the opening of the vibration plate 61, effectively preventing dust or other impurities from entering the opening of the vibration plate 61, keeping the inside of the equipment clean, and also playing a limiting role on the storage position of the telescopic plate 62, ensuring that the telescopic plate 62 can remain stable in the storage state.

[0045] During the retracting of the retractable plates 62, the feeding holes 42 are opened, so that the tungsten ores that do not pass through the holes 63 on the retractable plates 62 can fall smoothly. Since the retractable plates 62 are arranged in an inclined manner, the friction between the retractable plates 62 and the ores is small, which is beneficial to the sliding of the tungsten ores and also facilitates the smooth retracting of the retractable plates 62. In addition, the movement of the retractable plates 62 can be driven by the traction ropes driven by the motor to realize the retracting operation. The implementation manner in the embodiment is not limited in particular, as long as the retracting movement of the retractable plates 62 can be realized, and any driving mode with the function can be adopted.

[0046] The bottom plate of the screening bin 4 is fixed with a partition plate 41, which divides the lower space of the screening bin 4 into two parts. The first sorting hopper 81 and the second sorting hopper 82 are arranged on the two sides of the partition plate 41, respectively, and are used to carry tungsten ores of different sizes. The tungsten ores of different particle sizes separated by the screen can enter the two sorting hoppers, respectively, so that the screened ores can be effectively classified and stored. One end of the turnover plate 7 is movably connected to the upper end of the partition plate 41, and the turnover plate 7 is designed to be able to flexibly turn between different angles, so as to guide the screened tungsten ores to fall into the first sorting hopper 81 or the second sorting hopper 82, respectively. This design simplifies the ore diversion process, reduces manual operation, and improves the overall sorting efficiency.

[0047] The upper sides of the first sorting hopper 81 and the second sorting hopper 82 are respectively provided with feeding holes 42, which are located below the second screen 6. The area of the feeding holes 42 is the same as the downward projection area of the retractable plates 62 after being extended, so that the tungsten ores can fall into the hoppers smoothly regardless of the state of the retractable plates 62. In order to control the turning angle of the turnover plate 7, the two sides of the feeding holes 42 are provided with stop plates 43, which limit the turning angle of the turnover plate 7 and ensure that the turnover plate 7 guides the tungsten ores into the hoppers at the appropriate angle without deviation or error guidance.

[0048] Please refer to Figure 2 and Figure 4The cooperation process of the second screen 6, the turnover plate 7 and the sorting hopper 8 is as follows: when the turnover plate 7 is located at the left side, the telescopic plate 62 is in the extended state, the tungsten ore enters the feeding hole 42 through the fine hole 63 on the telescopic plate 62, due to the angle and position of the turnover plate 7, the ore slides along the inclined surface thereof and finally enters the second sorting hopper 82 at the right side, in this process, the fine tungsten ore is screened through the fine hole 63 and is separated through the feeding hole 42 under the action of gravity. Subsequently, when the turnover plate 7 is located at the right side, the telescopic plate 62 is in the retracted state, the larger ore particles that do not pass through the fine hole 63 will directly enter the feeding hole 42 and slide along the surface of the turnover plate 7 and finally fall into the first sorting hopper 81 at the left side. The left-right switching of the turnover plate 7 can control the flow direction of the ore particles of different sizes and can ensure that the ore particles enter the corresponding sorting hopper according to the size, so that accurate sorting is realized. When the first sorting hopper 81 and the second sorting hopper 82 are filled with tungsten ore, they can be taken out and replaced with new empty hoppers through simple replacement operation, which ensures the continuity of the sorting process and prevents the equipment from stopping or the sorting from being interrupted due to full hopper.

[0049] The mining machine in the embodiment is specially used for underground mines and can perform preliminary screening while mining tungsten ore. During the mining stage of the underground mine, the mining machine can directly perform preliminary crushing and screening of the mined tungsten ore, and the crushing and screening can be performed during the mobile mining process in the underground mine, so that preliminary classification can be performed based on the size of the ore, which helps to further screen the ore in a more accurate manner such as X-ray, image recognition and the like, thereby reducing the burden of subsequent ore processing, enabling the classification of the ore in the underground operation, avoiding the traditional step of transporting the unsorted ore to the ground for secondary processing, and greatly improving the efficiency of the operation under the mine. In the embodiment, the movement of the mining machine not only serves as a carrier for transportation and mining, but also provides additional vibration force for the screening process. During the driving of the mining machine, natural vibration is generated by the contact between the vehicle and the ground, and the vibration can be combined with the vibrating screen in the screening device to assist the vibration of the screen by the movement of the vehicle, thereby promoting the screening of the tungsten ore. This design of utilizing the vibration of the vehicle is particularly suitable for use in rougher mining areas, and the driving speed and road conditions will also have a certain influence on the screening effect, so the vibration frequency of the screen and the driving speed can be automatically adjusted to further optimize the screening effect. In addition, the power system (such as a hydraulic or electric system) of the mining machine can directly drive the vibration of the screening device and the movement of the telescopic cylinder, thereby reducing the need for independent motors and optimizing energy consumption configuration. For example, the hydraulic system of the mining machine can provide driving force for the first telescopic cylinder 52 and the second telescopic cylinder 64. In order to further improve the sustainability of the equipment, the power system of the mining machine can be equipped with a vehicle-mounted power generation device to recover kinetic energy during the operation of the vehicle and provide power supply for the screening device.

[0050] In this embodiment, the larger tungsten ore particles that fail to pass through the first screen 5 can be collected and processed in various ways. For example, a push plate mechanism can be designed for automatic cleaning. When the screening is completed, the push plate moves along the surface of the first screen 5, pushing the larger particles of ore that have not passed through to one side of the screening bin 4 and then to a collection bin. Alternatively, the first screen 5 can be designed as a hoistable structure. When the screening work is completed, the first screen 5 is lifted from the screening bin 4 by a lifting device and is dumped into a designated ore collection area or conveyor belt. The ore remaining on the first screen 5 can be smoothly discharged from the screening bin 4, avoiding the accumulation of a large amount of ore on the screen 5, which would affect subsequent screening work.

[0051] In summary, the present application provides a tungsten ore mining and sorting device that combines vibration screening, airflow assistance, and sorting hoppers to achieve the coordinated work of tungsten ore mining and sorting. The mining machine cooperates with the moving assembly 2 and the mining hopper 3 to seamlessly link the mining and screening processes of tungsten ore. The first screen 5 and the second screen 6 in the screening bin 4 achieve accurate screening of different sizes of ore through vibration. The airflow from the nozzles 9 not only blocks the spread of ore dust but also accelerates the screening of ore, especially by using the combination of the horizontal air outlet 91 and the inclined air outlet 92 to fully separate the tungsten ore during the screening process. The design of the sorting hoppers 81 and 82 ensures efficient collection of ore of different particle sizes, and the flexible adjustment of the turnover plate 7 further improves the accuracy and efficiency of sorting. In addition, through the simple hopper replacement mechanism, the sorting process can continue without interruption due to full hopper.

[0052] The technical solution of the present application has significant industrial application value in the field of tungsten ore mining and sorting. By effectively integrating the mining and sorting processes, the time and cost of traditional separation operations are reduced, and the production efficiency is greatly improved. In addition, the design of airflow-assisted screening and hopper replacement allows the device to operate stably in a high-intensity, continuous work environment, especially suitable for large-scale ore mining operations. This collaborative working mode not only improves the utilization rate of tungsten ore resources but also meets the industry trend of green environmental protection, which can promote the mining industry to develop towards high efficiency and environmental protection.
