Detailed Implementation

[0035] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0036] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” are used only to facilitate the description of the embodiments and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] like Figures 1 to 4 As shown, a feeding device includes a feeding box 1 and a conveying assembly 2 mounted on one side of the feeding box 1. A feed hopper 11 is provided at the top of the feeding box 1 for feeding ore materials into the feeding box. A dynamic flow guiding mechanism is provided inside the feeding box 1. This mechanism includes a guide plate 12 mounted at the outlet of the feeding box 1 and an angle adjustment mechanism 13 that drives the guide plate 12 to rotate. The angle adjustment mechanism 13 controls the material flow direction and flow rate by changing the angle of the guide plate 12. When it is necessary to adjust the material flow to a specific direction or increase / decrease the material flow rate, the angle adjustment mechanism 13 drives the guide plate 12 to rotate by the corresponding angle, thereby guiding the material to flow out as required. A flow guiding structure 21 is mounted at the inlet of the conveying assembly 2, the function of which is to guide the material flowing out of the feeding box 1 smoothly into the conveying assembly 2, preventing material spillage.

[0038] The beneficial effects of this embodiment are that the overall structure is simple and reasonable, and the dynamic flow guiding mechanism can flexibly adjust the material flow direction and flow rate according to actual production needs, significantly improving feeding accuracy and efficiency. The flow guiding structure 21 ensures that the material can smoothly enter the conveying component 2, reducing material spillage, improving the stability and reliability of the device operation, and meeting the needs of ore feeding under different working conditions.

[0039] The angle adjustment mechanism 13 includes a first drive motor 131 and a transmission device 132. The first drive motor 131 is fixed to the side wall of the feed box 1, and the transmission device 132 is connected to the guide plate 12. When the first drive motor 131 starts, the power it generates is transmitted to the guide plate 12 through the transmission device 132, causing the guide plate 12 to rotate and thus adjusting the angle of the guide plate 12. For example, when it is necessary to increase the material flow in a certain direction, the first drive motor 131 drives the transmission device 132 to rotate the guide plate 12 in that direction by a certain angle, thereby guiding more material to flow in that direction. Specifically, in this embodiment, the transmission device 132 includes a transmission gear and a driven gear that are meshed together; the output shaft of the first drive motor 131 is connected to the transmission gear, and the driven gear is mounted on the end of the guide plate 12, the end of which is provided with a rotating shaft for rotation. The first drive motor 131 drives the transmission gear to drive the driven gear, thereby causing the guide plate 12 to rotate around the rotating shaft.

[0040] The system employs a combination of motor drive and transmission device to achieve automated adjustment of the 12-degree angle of the guide vane. Operators can easily adjust the 12-degree angle of the guide vane simply by controlling the operation of the first drive motor 131, making operation convenient. Furthermore, this adjustment method offers high precision and can quickly adapt to the material flow direction and flow rate requirements under different working conditions, significantly improving the automation level and work efficiency of the device.

[0041] An arc-shaped guide surface is provided at the end of the guide plate 12. When the material flows out of the feed box 1 and passes through the guide plate 12, the arc-shaped guide surface can change the trajectory of the material. After contacting the arc-shaped guide surface, the material will enter the subsequent conveying stage more smoothly along the shape of the arc-shaped guide surface, instead of directly impacting the guide plate 12 or accumulating.

[0042] The arc-shaped guide surface design effectively reduces material collisions and accumulation during the flow process. Because the material flow is smoother, wear on the guide plate 12 is reduced, thus extending its service life. Simultaneously, the improved material flow stability enhances the continuity and stability of feeding, reducing production interruptions or uneven feeding caused by poor material flow.

[0043] An infrared material sensor 3 is installed inside the feeding hopper 1. The infrared material sensor 3 emits infrared rays and receives reflected signals. Based on parameters such as the intensity and duration of the reflected signals, it monitors the height of the material inside the feeding hopper 1 in real time. When the material height changes, the intensity and duration of the reflected signals also change accordingly. The sensor determines the material height by analyzing these changes.

[0044] By monitoring the material height within the feeding hopper 1 in real time, the infrared material sensor 3 provides accurate data for subsequent operations such as controlling the angle of the guide vane 12. For example, when the material height is too high, the system can adjust the angle of the guide vane 12 based on the sensor feedback to accelerate the material flow and prevent overflow; when the material height is too low, the angle of the guide vane 12 can be adjusted appropriately or the material input speed can be controlled to ensure the stability and reliability of the feeding process and avoid production problems caused by too much or too little material, such as equipment idling or insufficient material supply affecting production progress.

[0045] The dynamic flow guiding mechanism also includes a PLC controller, which is electrically connected to the infrared material sensor 3. The infrared material sensor 3 converts the monitored material height information into an electrical signal and transmits it to the PLC controller. The PLC controller analyzes and processes the received electrical signal according to a preset program and algorithm, and then controls the angle adjustment mechanism 13 to adjust the rotation angle of the guide plate 12, thereby achieving precise control of the material flow rate. For example, when the material height reaches a certain preset threshold, the PLC controller issues a command to cause the angle adjustment mechanism 13 to drive the guide plate 12 to rotate by a certain angle, increasing the material outflow.

[0046] The feeding process is automated through the collaboration of a PLC controller and an infrared material sensor 3. The PLC controller can adjust the angle of the guide vane 12 in real time according to the material height to ensure a stable material flow. This automated control method improves feeding accuracy and production efficiency, reduces manual intervention and labor intensity, and also avoids problems such as inaccurate feeding caused by human error.

[0047] The conveying assembly 2 includes a support frame 22, a conveyor belt 23, and a second drive motor 24. The conveyor belt 23 is mounted above the support frame 22, and the second drive motor 24 is connected to the conveyor belt 23 via a transmission structure such as a chain or belt. When the second drive motor 24 starts, the power it generates is transmitted to the conveyor belt 23 through the transmission structure, causing the conveyor belt 23 to move on the support frame 22, thereby realizing the conveying of materials. For example, ore material flowing out of the feed box 1 falls onto the conveyor belt 23, and as the conveyor belt 23 moves, the material is conveyed to the next process.

[0048] The conveying assembly 2 has a simple structure and stable operation. The second drive motor 24 provides power to the conveyor track 23, ensuring the normal operation of the conveyor track 23 and reliably conveying materials from the feed box 1 to the next process, meeting the basic requirements for ore feeding and conveying, and ensuring the smooth operation of the production process.

[0049] A high-frequency vibration motor 221 is fixedly installed on the outer wall of the support frame 22. The output end of the high-frequency vibration motor 221 is connected to a vibration rod 2211 extending to the other side of the support frame. When the high-frequency vibration motor 221 starts, the vibration rod 2211 generates high-frequency vibration and transmits the vibration to the support frame 22 and the conveyor belt 23. During the conveying process, the material is subjected to vibration, which reduces the friction between the material and the conveyor belt 23, thereby reducing the accumulation and adhesion of the material on the conveyor belt 23.

[0050] The high-frequency vibration motor 221 effectively prevents material accumulation on the conveyor belt 23, improving the smoothness of material conveying. This reduces the frequency of manual cleaning of the conveyor belt 23, increasing production efficiency. Simultaneously, it reduces the risk of equipment failure due to material accumulation, such as conveyor belt 23 jamming or motor overload, extending the equipment's service life.

[0051] The flow guiding structure 21 is detachably connected to one end of the conveyor belt 23, such as by bolts or clips. In actual production, when it is necessary to maintain or replace the flow guiding structure 21, or to adjust the flow guiding structure 21 according to the characteristics of different materials such as particle size and humidity, the operator can easily remove the flow guiding structure 21 from the conveyor belt 23.

[0052] This detachable connection method facilitates the maintenance, replacement, or adjustment of the flow guide structure 21 according to different material characteristics, improving the flexibility and adaptability of the device. It reduces maintenance costs and time, and allows for rapid adjustment of the flow guide structure 21 according to different working conditions, meeting diverse production needs. For example, when processing ore materials of different specifications, a suitable flow guide structure 21 can be replaced to improve feeding efficiency.

[0053] An adjusting element 211 is provided on the flow guiding structure 21, which can change the tilt angle of the flow guiding structure 21. Different materials have different flow characteristics; for example, materials with good flowability may require a smaller tilt angle, while materials with poor flowability may require a larger tilt angle. Adjusting the tilt angle by the adjusting element 211 can better adapt to the flow characteristics of different materials, improving the adaptability and efficiency of material conveying. A wear-resistant ceramic liner is provided on the surface of the flow guiding structure 21. When materials flow on the flow guiding structure 21, the wear-resistant ceramic liner can withstand the friction and impact of the materials, reducing the wear of the flow guiding structure 21.

[0054] The adjusting component 211 can flexibly adjust the tilt angle of the guide structure 21, improving the adaptability and efficiency of material conveying and allowing materials to flow more smoothly along the guide structure 21. Furthermore, it allows for the matching installation of feed boxes 1 and conveying components 2 with different height specifications; the wear-resistant ceramic liner effectively improves the wear resistance of the guide structure 21, extends its service life, reduces replacement costs and downtime due to wear, and lowers production costs.

[0055] A buffer structure 25, such as a spring or rubber pad, is installed between the support frame 22 and the conveyor track 23. When material falls onto the conveyor track 23, the material has a certain weight and impact force, which will impact the conveyor track 23 and the support frame 22. The buffer structure 25 can absorb the impact force of the material on the conveyor track 23, reducing the vibration and pressure on the conveyor track 23 and the support frame 22.

[0056] The buffer structure 25 effectively reduces the impact of materials on the conveyor belt 23 and support frame 22, reducing wear and damage to the equipment and extending its service life. At the same time, it reduces noise during operation, improves the stability and reliability of the device, and creates a quieter and more stable environment for production.

Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
