Description

Technical Field

[0001] This utility model relates to the field of ore conveying technology, specifically to a granular ore silo unloading and conveying mechanism. Background Technology

[0002] Ore bins are structures used for short-term storage and facilitating the loading of ore. The bottom of the bin is generally higher than the receiving port of the loading container or transport equipment. After the bin gate is opened, the ore is unloaded to achieve the loading purpose, which can reduce the physical labor during loading and has a high loading efficiency.

[0003] Currently, ore silos typically hold granular ore. When the granular ore is being fed and conveyed, the bottom of the silo is at a certain height from the conveying equipment. This results in a significant impact force on the granular ore as it falls due to its own weight. This impact force directly affects the service life of the conveying equipment, requiring frequent maintenance and repair. Based on this, a granular ore silo feeding and conveying mechanism is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a granular ore silo feeding and conveying mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a granular ore silo feeding and conveying mechanism, comprising a silo body, a discharge port at the lower end of the silo body, a conveying device placed below the discharge port, a box mounted on the surface of the silo body below the discharge port via a frame, multiple connecting shafts rotatably mounted between the front and rear ends inside the box, buffer plates mounted on the surface of each connecting shaft, the multiple buffer plates being arranged in an alternating inclined manner, a buffer assembly adjustablely mounted below each buffer plate, and a discharge plate adjustablely mounted inside the box at the front and rear of the lowest buffer plate.

[0006] Preferably, the conveying equipment is a scraper conveyor.

[0007] Preferably, the buffer assembly includes a movable plate, a guide rod, a contact plate, a spring, and a buffer pad. A movable plate is movably installed below each buffer plate.

[0019] 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.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4 As shown, the granular ore silo feeding and conveying mechanism of this embodiment includes a silo body 1. A discharge port 2 is provided at the lower end of the silo body 1 for discharging granular ore from inside the silo body 1. A conveying device 3 is placed below the discharge port 2 for conveying the granular ore. A housing 4 is mounted on the surface of the silo body 1 below the discharge port 2 via a frame. Multiple connecting shafts 5 are rotatably mounted between the front and rear ends inside the housing 4. Buffer plates 6 are mounted on the surface of each connecting shaft 5. The multiple buffer plates 6 are arranged in a staggered and inclined manner. The staggered placement of the multiple buffer plates 6... It can gradually reduce the impact force generated when the granular ore falls, effectively preventing the impact force generated when the granular ore is fed from acting directly on the conveying equipment 3, thus avoiding affecting the service life of the conveying equipment 3. A buffer component is installed adjustablely below the buffer plate 6 to provide a certain buffering force to the buffer plate 6. The discharge plate 8 is installed adjustablely inside the box 4 at the front and rear of the bottom buffer plate 6. By adjusting the distance between the two discharge plates 8, the discharge width of the granular ore can be adjusted, so that the ore particles fall completely onto the conveying equipment 3. It can be used with conveying equipment 3 of various sizes.

[0022] Specifically, conveying equipment 3 is a scraper conveyor, which is a mature existing technology.

[0023] Furthermore, the buffer assembly includes a movable plate 701, a guide rod 702, a contact plate 703, a spring 704, and a buffer pad 705. A movable plate 701 is movably mounted below each buffer plate 6. Guide rods 702 are installed at the front and rear of the upper end of the movable plate 701 through through holes. A contact plate 703 is mounted on the upper end of both guide rods 702. A spring 704 is mounted on the surface of the guide rod 702 between the contact plate 703 and the movable plate 701. A buffer pad 705 is mounted on the lower end of the spring 704. The spring 704 generates elastic force to support the contact plate 703. When granular ore falls onto the buffer plate 6, the buffer plate 6 compresses the spring 704 through the contact plate 703, and the spring 704 buffers the impact force. The guide rod 702 guides the movement of the contact plate 703.

[0024] Furthermore, an electric push rod 9 is installed at one end of the box 4 on the lower side of the buffer plate 6. The output end of the electric push rod 9 extends to the lower side of the buffer plate 6, and the moving plate 701 is connected to the output end of the electric push rod 9. By controlling the extension and retraction of the electric push rod 9, the moving plate 701 is moved. By adjusting the position of the moving plate 701, the spacing between adjacent buffer plates 6 and the tilt angle of the buffer plate 6 can be adjusted according to the size of the ore particles.

[0025] Furthermore, the inner walls of the front and rear boxes 4 of the movable plate 701 are provided with movable grooves 10, and the front and rear ends of the movable plate 701 are located inside the movable grooves 10. The movable grooves 10 play a supporting and guiding role for the movable plate 701.

[0026] Furthermore, screws 11 are installed at both the front and rear ends of the box 4 at the bottom buffer plate 6 through screw holes. One end of the screw 11 is rotatably connected to the connecting plate 12 inside the box 4. One end of the discharge plate 8 is hinged to the upper end of the connecting plate 12. The box 4 above the electric push rod 9 is provided with a placement groove 13. The discharge plate 8 is located inside the placement groove 13. The other end of the screw 11 is equipped with a handle 14. By rotating the handle 14, the screw 11 is rotated. The screw 11 can adjust the position of the connecting plate 12. The connecting plate 12 can drive the discharge plate 8 to move, thereby adjusting the gap between the two discharge plates 8. This allows for adjustment of the discharge width of the box 4, making it easier for ore particles to fall onto the conveying equipment 3. This is suitable for conveying equipment 3 of various sizes.

[0027] The usage method of this embodiment is as follows: granular ore is placed inside the hopper body 1. The electric push rod 9 is extended and retracted by controlling it. The electric push rod 9 drives the moving plate 701 and the contact plate 703 to move, which can adjust the tilt angle of the buffer plate 6. When the granular ore is discharged evenly from the discharge port 2, the granular ore falls onto the uppermost buffer plate 6. The buffer plate 6 moves downward due to the impact force. The buffer plate 6 compresses the elastic spring 704 through the contact plate 703. The compression of the elastic spring 704 buffers the impact force. Under the action of gravity, the granular ore falls from the buffer plate 6 and onto the next layer of buffer plate 6. Multiple buffer plates 6 can provide multi-level buffering for the granular ore, effectively reducing the impact force generated when the ore particles fall directly and causing damage to the conveying equipment 3, and effectively extending the service life of the conveying equipment 3.

[0028] 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.
