Abstract
Description
Technical Field
[0001] This utility model relates to the field of mining machinery, specifically a vibrating screen for mining stone. Background Technology
[0002] In mining operations, the extracted stones are often of varying sizes and mixed particle sizes. To meet the stringent requirements of subsequent processing steps for stone particle size, such as in the production of building aggregates and ore beneficiation, accurate particle size classification is a key prerequisite for ensuring product quality and production efficiency. This makes efficient and reliable screening equipment indispensable. By effectively screening stones through vibrating screens, stones can be divided into different grades according to particle size, so as to provide raw materials of suitable specifications for subsequent crushing, grinding, smelting and other processes.
[0003] However, traditional vibrating screens for mining stone have revealed many drawbacks in practical applications. Firstly, their screening efficiency is low; when faced with a large amount of stone, they cannot complete sufficient screening in a short time, resulting in slow production progress. Secondly, their screening accuracy is poor, often resulting in the mixing of stones of different particle sizes, affecting the quality stability of subsequent processed products. These shortcomings not only increase production costs but also severely restrict the capacity expansion and economic growth of mining enterprises. Therefore, we propose a new type of vibrating screen for mining stone. Utility Model Content

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a vibrating screen for mining stone materials, which has the following beneficial effects:
[0015] 1. The vibrating screen for quarry stone uses a stone feeding port and stone inlet hopper design to quickly and smoothly feed stone into the primary screening drum, ensuring high feeding efficiency and preventing stone accumulation and blockage during feeding. Secondly, the rotating motor in the rolling structure drives the primary screening drum to perform preliminary screening of the stone, separating some larger particles in advance, reducing the screening burden on the subsequent vibrating screen box, and making the entire screening process more efficient.
[0016] 2. The quarry uses a vibrating screen. The screen mesh is fixed inside the vibrating screen box near the top, which allows for immediate screening of the stone after it enters the box. This reduces ineffective movement of the stone within the box and prevents excessive mixing of stones of different particle sizes. The discharge ports 1 and 2 on the side of the vibrating screen box, as well as the corresponding discharge port 3 at the bottom, can accurately classify and discharge the stone according to its particle size, effectively preventing the mixing of stones of different particle sizes.
[0017] 3. The springs and pressure covers in the buffer structure of the vibrating screen for ore mining not only reduce the impact of the vibration of the vibrating screen box on other components, but also absorb vibration energy to a certain extent, protect the key components of the device, and reduce the risk of component damage due to vibration. The vibration motor fixing plate is designed in a V shape and cooperates with the vibration motor support seat to make the vibration motor installation more stable, reduce the displacement and wear of the vibration motor during operation, and extend the service life of the vibration motor.

Detailed Implementation
[0024] 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.
[0025] Please see Figure 1-5 A vibrating screen for mining stone includes a bottom fixed plate 1. A first support frame 2 is fixedly installed on one side of the top of the bottom fixed plate 1. The first support frame 2 is stepped. A conveying structure is provided in the middle of the first support frame 2. A rolling structure is provided on the lower side of the stepped first support frame 2. A feeding structure is provided on the top of the stepped first support frame 2. A second support frame 12 is fixedly installed on the other side of the top of the bottom fixed plate 1. A buffer structure is provided on the top of the second support frame 12. A connecting rib 16 is fixedly installed on the top of the buffer structure. A vibrating screen box 17 is fixedly connected to the side of the connecting rib 16. A screen 18 is fixedly installed inside the vibrating screen box 17 near the top. A discharge port 19 and a discharge port 20 are opened on the side of the vibrating screen box 17. A discharge port 3 21 is opened on the bottom of the vibrating screen box 17 corresponding to the discharge port 19 and the discharge port 20. A vibrating structure is provided at the bottom of the vibrating screen box 17.
[0026] Furthermore, the conveying structure includes a support rod 3, baffles 4, a conveyor motor 5, and a conveyor belt 6. The support rod 3 is fixedly installed on both sides of the inside of the first support frame 2. A set of parallel and vertical baffles 4 is fixedly installed on the top of the support rod 3. The conveyor motor 5 is fixedly installed on the outer side of the baffles 4. The output shaft of the conveyor motor 5 is connected to a roller. The conveyor belt 6 is rotatably installed between the two baffles 4. The two ends of the conveyor belt 6 are sleeved on the rollers connected to the output shaft of the conveyor motor 5. The support rod 3 in the conveying structure not only provides installation support for the conveyor belt 6, but its height and position design also ensures a reasonable connection between the conveyor belt 6 and the primary screening roller 9 and the vibrating screen box 17, so that the stone can be smoothly transferred. In addition to limiting the movement range of the stone on the conveyor belt 6 and preventing the stone from falling, the baffles 4 can also guide the stone into the vibrating screen box 17 in a relatively uniform state. The power of the conveyor motor 5 is precisely matched so that it can stably drive the conveyor belt 6 according to the stone conveying volume and screening rhythm, ensuring uniform stone conveying and avoiding the impact of excessively fast or slow conveying speed on screening efficiency and quality.
[0027] Furthermore, the rolling structure includes a mounting plate 7, a rotating motor 8, and a primary screening drum 9. The mounting plate 7 is fixedly mounted on the side of the first support frame 2, and the rotating motor 8 is fixedly mounted on the outer side of the mounting plate 7. The output shaft of the rotating motor 8 is connected to the primary screening drum 9. Both ends of the primary screening drum 9 are rotatably mounted on the side of the mounting plate 7. The mounting plate 7 is made of high-strength material, which can stably support the rotating motor 8 and the primary screening drum 9. It is not easily deformed under long-term vibration and gravity. The rotation speed of the rotating motor 8 can be adjusted according to the characteristics of the stone. For stones with large particle size differences, appropriately increasing the rotation speed can enhance the primary screening effect. For fragile or easily abraded stones, reducing the rotation speed can reduce stone breakage. The size and shape of the screen holes of the primary screening drum 9 are carefully designed. The screen hole specifications vary in different areas. The screen holes near the feed end are larger and are used to initially screen out larger particles. As the stone moves in the drum, the screen holes gradually become smaller, further improving the accuracy of the primary screening.
[0028] Furthermore, the feeding structure includes a stone inlet 10 and a stone inlet hopper 11. The stone inlet 10 is fixedly installed on the top of the first support frame 2, and the bottom of the stone inlet 10 is fixedly connected to the stone inlet hopper 11. The stone inlet hopper 11 is bucket-shaped, and the bottom of the stone inlet hopper 11 extends into the interior of the primary screening drum 9. The opening size of the stone inlet 10 can be adjusted according to actual production needs. When a large amount of stone needs to be processed, the opening is enlarged to increase the feeding speed. When processing small batches or special stones, the opening is reduced to facilitate precise control of the feeding amount. The inner wall of the stone inlet hopper 11 is smoothed to reduce the friction of the stone during the sliding process. At the same time, its bucket-shaped design can gather the stone, so that the stone enters the primary screening drum 9 in a concentrated manner, avoiding the stone from being dispersed and causing uneven feeding.
[0029] Furthermore, the buffer structure includes a pressure cap 13, a spring 14, and a spring support seat 15. The pressure cap 13 is fixedly installed on the top of the second support frame 12. The spring 14 is fixedly installed on the top of the pressure cap 13, and the pressure cap 13 is also fixedly installed on the top of the spring 14. The spring support seat 15 is fixedly installed on the top of the pressure cap 13 above the spring 14. The spring support seat 15 is U-shaped, and a connecting rib 16 is fixedly installed inside the U-shape of the spring support seat 15. The pressure cap 13 and the spring 14 fit tightly together. The weight and material of the pressure cap 13 have been optimized so that it can effectively transmit the elastic force of the spring 14 and maintain stability during vibration. The elastic coefficient of the spring 14 has been rigorously tested and screened so that it can quickly return to its original shape while absorbing vibration energy, ensuring the continuity of the buffering effect. The U-shaped design of the spring support seat 15 provides a stable installation base for the connecting rib 16. Its internal fixing structure ensures that the connecting rib 16 and the spring support seat 15 are firmly connected, preventing loosening during vibration, thereby effectively protecting the vibrating screen box 17 and other components.
[0030] Furthermore, the vibration structure includes a vibration motor fixing plate 22, a vibration motor support base 23, and a vibration motor 24. The vibration motor fixing plate 22 is fixedly installed at the bottom of the vibrating screen box 17. The vibration motor fixing plate 22 is V-shaped. A set of symmetrical vibration motor support bases 23 are fixedly installed on the inclined outer wall of the V-shape of the vibration motor fixing plate 22. The vibration motor 24 is fixedly installed inside the vibration motor support base 23. The V-shaped design of the vibration motor fixing plate 22 not only enhances the support stability of the vibration motor 24, but also changes the propagation direction and intensity distribution of the vibration, so that the vibration is transmitted more evenly to all parts of the vibrating screen box 17. The vibration motor support base 23 is made of shock-absorbing material. While fixing the vibration motor 24, it can further reduce the noise and vibration generated by the vibration motor 24 during operation and reduce the impact on other components. The model of the vibration motor 24 is selected according to the size and weight of the vibrating screen box 17 and the required screening effect. The vibration frequency and amplitude generated by it can meet the screening requirements of different particle sizes of stone, ensuring the efficiency and accuracy of screening.
[0031] Structural Description:
[0032] Bottom fixing plate 1: It is the basic support component of the entire vibrating screen. It is made of sturdy material and is installed horizontally at the bottom.

[0033] First support frame 2: Fixedly installed on one side of the top of the bottom fixed plate 1, in a stepped shape. This shape facilitates the layered installation of the conveying structure, rolling structure and feeding structure, making the layout of each structure reasonable and facilitating the processing of stone at different heights and positions.
[0034] Support rod 3: Installed on both sides inside the first support frame 2 to provide support. Its top is used to install baffle 4 and conveyor belt 6 to ensure that the conveyor belt 6 is at a suitable height and angle so that the stone can be transported smoothly on the conveyor belt.
[0035] Baffle 4: Installed on the top of support rod 3, in a parallel and vertical state. Its main function is to limit the movement range of the stone on the conveyor belt 6, prevent the stone from falling during the conveying process, and guide the stone into the vibrating screen box 17 in a more uniform state.
[0036] Conveyor motor 5: Installed on the outer side of baffle 4, with output shaft connected to roller, it provides power for the operation of conveyor belt 6. By driving the roller, it drives the conveyor belt 6 to rotate, so that the stone moves smoothly on the conveyor belt. Its power is matched according to the stone conveying volume and screening rhythm to ensure uniform conveying.
[0037] Conveyor belt 6: Installed between the two side baffles 4, with both ends sleeved on the rollers connected to the output shaft of the conveyor motor 5. It is the conveying carrier of stone. Driven by the conveyor motor 5, it smoothly conveys the stone that has been pre-screened by the primary screening drum 9 to the vibrating screen box 17.
[0038] Mounting plate 7: It is fixedly installed on the side of the first support frame 2 and is made of high-strength material. It provides a stable mounting base for the rotating motor 8 and the primary screening drum 9. It is not easily deformed under long-term vibration and gravity, ensuring the normal operation of the rolling structure.
[0039] Rotary motor 8: Installed on the outer side of mounting plate 7, with output shaft connected to primary screening drum 9. After starting, it drives primary screening drum 9 to rotate. Its speed can be adjusted according to the characteristics of the stone. Through rotation, the stone is tumbled and screened in primary screening drum 9, realizing the function of preliminary separation of larger particles.
[0040] Primary screening drum 9: It is mounted on the side of the mounting plate 7 at both ends. It has screen holes of different specifications inside. After the stone enters from the feeding structure, larger particles are screened out during the rotation of the drum, which reduces the screening burden of the subsequent vibrating screen box 17 and improves the overall screening efficiency.
[0041] Stone feeding port 10: It is fixedly installed on the top of the first support frame 2. The size of the opening can be adjusted according to production needs. It is the inlet of the stone feeding device, which makes it convenient for operators to feed stones. By cooperating with the stone feeding hopper 11, it ensures efficient and controllable feeding.
[0042] Stones enter hopper 11: It is hopper-shaped, with the bottom extending into the interior of the primary screening drum 9 and fixedly connected to the bottom of the stone feeding port 10. Its hopper-shaped structure can collect stones, allowing them to enter the primary screening drum 9 in a concentrated manner. The inner wall is smooth, reducing the friction of stone slippage and avoiding uneven feeding.
[0043] Second support frame 12: Installed on the other side of the top of the bottom fixed plate 1, the top is used to install the buffer structure. It, together with the first support frame 2, supports the entire vibrating screen, ensuring the stability of the device and providing reliable support for the buffer structure and the vibrating screen box 17.
[0044] Pressure cap 13: It is fixedly installed on the top of the second support frame 12 and cooperates with the spring 14. Its weight and material have been optimized so that it can effectively transmit the elastic force of the spring 14 and maintain stability during vibration, thus playing a role in buffering and protection.
[0045] Spring 14: Both the top and bottom are equipped with pressure caps 13, whose elastic coefficient has been rigorously tested and screened. When the vibrating screen is working, the spring 14 absorbs the vibration energy generated by the vibrating screen box 17, reduces the impact of vibration on other components, and ensures the continuity of the buffering effect.
[0046] Spring support seat 15: U-shaped, installed on top of the cover 13 above the spring 14. The U-shaped internal fixed connection plate 16 provides a stable installation base for the connection plate 16. The internal fixing structure ensures a firm connection and prevents loosening during vibration.
[0047] Connecting rib 16: It is fixedly connected to the vibrating screen box 17 on the side and fixed at the bottom by the spring support seat 15. It transmits the buffering effect of the buffer structure to the vibrating screen box 17, enhances the overall structural strength of the device, and ensures the stability of the vibrating screen box 17 during vibration.
[0048] Vibrating screen box 17: It is connected to the buffer structure through the connecting plate rib 16. The screen 18 is fixedly installed inside near the top. The side has a discharge port 19 and a discharge port 20. The bottom has a discharge port 31. It is the main place for stone screening. Under the action of the vibrating structure, the stone is accurately screened and classified.
[0049] Screen 18: Fixed inside the vibrating screen box 17 near the top, the surface is covered with screen holes of a specific diameter. When the vibrating screen box 17 vibrates, the stone jumps and rolls on the screen. Stones smaller than the screen holes pass through the screen, realizing the function of grading by particle size.
[0050] Feed port 19: Located on the side of the vibrating screen box 17, it is used to discharge some stone material that is larger than the aperture of the screen 18. Depending on the particle size of the stone and the screening requirements, different feed ports can correspond to different particle size ranges of stone material, so as to achieve accurate classification and discharge.
[0051] Feed port 20: Both feed port 1 and feed port 19 are located on the side of the vibrating screen box 17. They are also used to discharge stones larger than the screen mesh size. They work together with feed port 19 to further refine the classification and discharge of stones of different particle sizes and improve the screening accuracy.
[0052] Discharge port 3 21: Located at the bottom of the vibrating screen box 17, corresponding to the side of discharge port 1 19 and discharge port 2 20, it is used to discharge stone materials that meet specific particle size requirements and is an important discharge channel for qualified stone materials after screening.
[0053] Vibration motor mounting plate 22: Fixedly installed at the bottom of the vibrating screen housing 17, it is V-shaped. This shape not only enhances the support stability of the vibration motor 24, but also changes the propagation direction and intensity distribution of the vibration, so that the vibration is transmitted more evenly to all parts of the vibrating screen housing 17.
[0054] Vibration motor support base 23: Installed on the V-shaped inclined outer wall of the vibration motor fixing plate 22, and symmetrically distributed. It is used to fix the vibration motor 24. It is made of shock-absorbing material. While fixing the motor, it reduces the noise and vibration generated by the vibration motor 24 during operation and reduces the impact on other components.
[0055] Vibration motor 24: Installed in the vibration motor support 23, it generates strong vibration after starting. Its vibration frequency and amplitude are selected according to the size and weight of the vibrating screen box 17 and the required screening effect, driving the vibrating screen box 17 to vibrate at high frequency, so as to achieve effective screening of stone.
[0056] Working principle: During operation, stones are poured in through the stone feeding port 10, which is fixed to the top of the first support frame 2. The bottom of the port is connected to a bucket-shaped stone inlet 11, with the bottom of the inlet extending into the primary screening drum 9. This design allows the stones to slide smoothly into the primary screening drum 9, ensuring efficient feeding and preventing blockages. The stones entering the primary screening drum 9 begin preliminary screening under the action of the rolling structure. The rolling structure consists of a mounting plate 7 installed on the side of the first support frame 2, a rotating motor 8 on the outer side of the mounting plate 7, and the primary screening drum 9 connected to the output shaft of the rotating motor 8. After the rotating motor 8 starts, it drives the primary screening drum... As the drum 9 rotates, the stones tumble inside. Some larger particles, unable to pass through the drum screen holes, are separated prematurely, reducing the screening burden on the subsequent vibrating screen housing 17 and improving overall screening efficiency. The stones that have passed the initial screening fall onto the conveying structure, which includes support rods 3 fixed to the two sides inside the first support frame 2, parallel vertical baffles 4 at the top of the support rods 3, a conveying motor 5 on the outer side of the baffles 4, and a conveyor belt 6 rotatably installed between the two baffles 4. The two ends of the conveyor belt 6 are sleeved on rollers connected to the output shaft of the conveying motor 5. When the conveying motor 5 operates, it drives the conveyor belt 6 to move, smoothly conveying the stones to the vibrating screen housing 17.
[0057] After the stone material enters the vibrating screen housing 17, the vibration structure begins to function. The vibration structure includes a V-shaped vibrating motor mounting plate 22 fixed to the bottom of the vibrating screen housing 17, vibrating motor support seats 23 symmetrically installed on the inclined outer wall of the vibrating motor mounting plate 22, and a vibrating motor 24 installed within the vibrating motor support seats 23. The vibrating motor 24 starts, generating strong vibrations that drive the vibrating screen housing 17 to vibrate at high frequency. The screen 18 is fixed inside the vibrating screen housing 17 near the top. Under the vibration, the stone material continuously jumps and tumbles on the screen. Stone material smaller than the mesh size of the screen 18 passes through the screen and falls below the vibrating screen housing 17, while stone material larger than the mesh size moves towards the discharge port 19 and discharge port 20 on the side of the vibrating screen housing 17 according to the vibration direction and its own gravity. Stones that meet specific particle size requirements are discharged from the two discharge ports. Stones that meet specific particle size requirements are discharged from the discharge port 21 on the bottom side corresponding to discharge port 19 and discharge port 20, achieving precise classification. In the entire screening process, the buffer structure plays an important auxiliary role. The buffer structure consists of a pressure cover 13 fixed to the top of the second support frame 12, a spring 14 on the top of the pressure cover 13, and a U-shaped spring support seat 15 on the top of the pressure cover 13 above the spring. The spring support seat 15 is internally connected to a connecting rib 16, which is connected to the vibrating screen box 17. The spring 14 can effectively absorb the energy generated by the vibration of the vibrating screen box 17, reduce the impact of vibration on other components, reduce the risk of component damage due to vibration, make the vibrating screen more stable during operation, and ensure the continuous operation of screening.
