Description

Technical Field

[0001] This utility model relates to the field of ore mining technology, specifically to an automatic identification device for foreign inclusions in iron ore. Background Technology

[0002] In the mining production process, after the ore is processed through blasting, crushing and grinding, it needs to be transferred to the subsequent processing or storage stages through an efficient and continuous material conveying system.

[0003] An existing patent (publication number: CN218200646U) discloses a conveyor for conveying ore, including support columns, of which two sets are provided. A fixing block is provided at the top of each set of support columns. A guide roller is provided at the front end of each fixing block, and a conveyor belt is provided on the prime guide roller. A side plate is provided on the left side of each fixing block, and a mounting frame is provided on the front side of each fixing block. A scraper is provided at the bottom left end of the mounting frame. A mounting groove is provided on the front surface of each fixing block, and a movable block is provided within the mounting groove. A threaded rod is provided in the center of the mounting groove. Fine ore particles adhering to the conveyor belt will be scraped off by the first scraper, causing the ore particles to detach from the conveyor belt and slide off after passing through the first scraper, thus facilitating the collection of ore particles.

[0004] The aforementioned equipment can detach ore particles adhering to the conveyor belt and allow them to slide off the first scraper, thus facilitating the collection of ore particles. However, during the iron ore mining process, foreign matter and some smaller particles not adhering to the conveyor belt may be mixed in with the ore. The aforementioned equipment cannot separate the foreign matter, affecting the processing and handling of subsequent processes. Utility Model Content

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The automatic identification device for foreign inclusions in iron ore in this embodiment includes two belt conveyors 1, which are in contact with each other and convey in opposite directions.

[0033] Please see Figure 1, Figure 2 and Figure 4 A gantry frame 2 is installed above two belt conveyors 1. A vision inspection module 3 for detecting foreign objects is fixedly installed on the front of the gantry frame 2. A sorting mechanism 4 for clamping and transferring foreign objects is installed on the inner top wall of the gantry frame 2. Through the vision inspection module 3, the material conveyed on one of the belt conveyors 1 can be detected, foreign objects can be identified, and the sorting mechanism 4 can be used to sort and transfer the foreign objects. The sorting mechanism 4 includes a threaded rod 10. The two ends of the threaded rod 10 are rotatably connected to the inner wall of the gantry frame 2, and the outer surface of the threaded rod 10 is threaded with... The movable block 11 abuts against the inner top wall of the gantry 2. A cylinder 12 is fixedly installed at the bottom end of the movable block 11, and a pneumatic mechanical claw 13 is fixedly installed at the bottom end of the cylinder 12. With the above configuration, the purpose of gripping and transferring foreign objects on the belt conveyor 1 can be achieved. A motor 15 is installed on one side of the gantry 2. The output end of the motor 15 is fixedly connected to one end of the threaded rod 10. With the motor 15, the threaded rod 10 can be driven to rotate, thereby controlling the lateral movement of the movable block 11 to achieve the purpose of positioning foreign objects.

[0034] Please see Figure 1 , Figure 2 and Figure 3 Adjusting sleeves 5 are fixedly installed on the opposite sides of the rear ends of the two belt conveyors 1. Adjusting blocks 6 are slidably inserted into the interior of each of the two adjusting sleeves 5. Shaft discs 7 are fixedly connected to the top of each of the two adjusting blocks 6. A screw conveyor shaft 8 is rotatably connected between the two shaft discs 7. Screw plates 9 are fixedly connected to the outer surface of the screw conveyor shaft 8. A gap is provided between the screw plates 9 and the two belt conveyors 1 to facilitate the passage of small particles and slag. The screw plates 9 can block qualified ore and push qualified ore to the adjacent belt conveyor 1 for conveying by rotating the screw plates 9. Unqualified small particles of ore and slag can continue to be conveyed through the gap, thereby achieving the effect of classified conveying. The size of the gap can be adjusted by sliding the adjusting blocks 6 and adjusting sleeves 5, so as to facilitate adjustment according to the user's needs. The adjusting blocks 6 and adjusting sleeves 5 can be fixed together by bolts.

[0035] Please see Figure 1 , Figure 2 and Figure 3The spiral edge of the auger plate 9 is wrapped with wear-resistant rubber to improve its wear resistance. One side of one of the shaft discs 7 is equipped with a motor 16, and the output end of the motor 16 is fixedly connected to one end of the auger shaft 8. The auger shaft 8 enables the auger plate 9 to rotate. One side of the belt conveyor 1 is equipped with a waste collection box 14, which enables the centralized collection of foreign objects for subsequent processing by workers. The vision detection module 3, the sorting mechanism 4, and the motor 16 are all electrically connected to the external control system. The preset image recognition algorithm enables automatic positioning of foreign objects and links the sorting mechanism 4 to perform coordinate positioning and gripping actions.

[0036] This embodiment of an automatic identification device for foreign inclusions in iron ore achieves automatic identification, positioning, and grasping of non-ore foreign objects mixed in iron ore through the coordinated work of the vision detection module 3 and the sorting mechanism 4. This significantly reduces the cost of manual inspection, improves sorting efficiency and accuracy, and avoids damage to subsequent processing equipment by foreign objects. The reverse-running belt conveyor 1, combined with the adjustable gap auger plate 9 structure, can both block qualified ore and guide it to the adjacent belt conveyor 1, and screen out unqualified small slag particles, realizing the synchronous classification and conveying of ore and impurities, and optimizing the material handling process.

[0037] The working principle of the above embodiment is as follows: After being crushed, the iron ore is transported forward by the first belt conveyor 1. When the ore passes under the gantry 2, the vision detection module 3 continuously scans the surface of the conveyor belt. Through a preset image recognition algorithm, such as based on shape, color, or texture features, the ore image is analyzed in real time to automatically identify non-ore foreign objects such as metal scraps and plastics, and transmit the coordinate information of the foreign objects to the control system. After receiving the foreign object position signal, the control system starts the sorting mechanism 4: the motor 15 drives the threaded rod 10 to rotate, which drives the moving block 11 to move laterally along the gantry 2 to directly above the foreign object; the cylinder 12 pushes the pneumatic mechanical claw 13 to descend vertically, clamp the target foreign object and lift it up, and then the moving block 1... 1. After resetting, the mechanical claw transfers the foreign objects to the waste storage bin 14 for centralized storage, completing the separation of foreign objects. The unidentified qualified ore continues to be conveyed. The motor 16 drives the auger shaft 8 to rotate, which in turn drives the auger blades 9 to rotate continuously. Its spiral blades block large qualified ore particles and push them to the adjacent second conveyor, realizing the diversion of qualified ore. Meanwhile, small slag particles and debris continue to be conveyed along the original conveyor through the gap between the auger blades 9 and the belt, completing the synchronous classification of ore and impurities. By manually adjusting the up and down sliding position of the adjusting block 6 in the adjusting sleeve 5, the gap height between the auger blades 9 and the belt conveyor 1 can be changed to adapt to the grading requirements of different particle sizes of ore. For example, increasing the gap can allow smaller particles to pass through.
