[0002] Ore sorting is one of the core links in mineral processing, which refers to the process of separating valuable mineral components from the as-mined raw ore from waste rock or other impurities through physical, chemical or biological methods. On this premise, an innovative application of the optoelectronic sorting and waste rejection technology has been invented, the core of which lies in the precise recognition by an industrial camera, and then controlling the compressed air of the air storage tank at the end of the conveyor belt for blowing.

Detailed implementation manners

[0021] To make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figures 1 - 10, the present invention provides a technical solution: an ore uniform dispersion and feeding device and a dual-recognition sorting system, including a conveyor belt 1 and a support frame 2. A support platform 3 is installed between the conveyor belt 1 and the support frame 2. A uniform dispersion and feeding mechanism is provided on the support platform 3. The uniform dispersion and feeding mechanism includes a first mounting frame 401 and a third reciprocating rod 404. The first mounting frame 401 is fixedly installed on the inner top wall of the support platform 3. A first reciprocating rod 402 is slidably sleeved inside the first mounting frame 401. A second reciprocating rod 403 is slidably sleeved inside the first reciprocating rod 402. The third reciprocating rod 404 is installed at one end of the second reciprocating rod 403 by bolts. A square frame 405 is integrally formed at the other end of the third reciprocating rod 404. A uniform dispersion seat 406 is installed at the bottom of the third reciprocating rod 404 by bolts and a mounting plate. A through cavity 407 penetrating left and right is formed on the uniform dispersion seat 406. The left inner side wall of the through cavity 407 is chamfered to facilitate the entry of coal gangue into the inside of the through cavity 407. A plurality of partition plates 408 are arranged inside the through cavity 407. The plurality of partition plates 408 are arranged in a linear array. A first rotating rod 409 is rotatably installed on the inner top wall of the support platform 3. A first eccentric wheel 410 is fixedly installed at the bottom of the first rotating rod 409. The first eccentric wheel 410 is located inside the square frame 405. The center of the first eccentric wheel 410 intersects with the central axis of the square frame 405. By providing the uniform dispersion and feeding mechanism, when the coal gangue on the conveyor belt 1 is transported to the right, the first rotating rod 409 is rotated to drive the first eccentric wheel 410 to rotate. The protruding part of the first eccentric wheel 410 squeezes the rear inner wall of the square frame 405, causing the square frame 405 to drive the second reciprocating rod 403 to squeeze the first reciprocating rod 402, so that the second reciprocating rod 403, the first reciprocating rod 402 and the third reciprocating rod 404 move backward, thereby driving the uniform dispersion seat 406 and the partition plates 408 to move backward. When the protruding part of the first eccentric wheel 410 squeezes the left inner wall of the square frame 405, the second reciprocating rod 403 slides inside the first reciprocating rod 402. At this time, the first reciprocating rod 402 remains stationary, and the second reciprocating rod 403 drives the third reciprocating rod 404, the uniform dispersion seat 406 and the partition plates 408 to move leftward. Similarly, when the protruding part of the first eccentric wheel 410 squeezes the front inner wall and the right inner wall of the square frame 405, the uniform dispersion seat 406 and the partition plates 408 move forward and rightward respectively, so that the uniform dispersion seat 406 and the partition plates 408 move reciprocally above the conveyor belt 1 in a square trajectory, thereby uniformly spreading and flattening the coal gangue on the conveyor belt 1, avoiding the problem that the subsequent coal gangue accumulates and causes the industrial camera 603 to be unable to accurately identify. The flattened coal gangue continues to be transported to the right on the conveyor belt 1. After being accurately identified by the industrial camera 603 and X-rays, at the end of the conveyor belt 1, through the compressed blowing operation of the air storage tank at the bottom of the conveyor belt 1, the coal and gangue are accurately blown into the coal treatment chamber and the gangue treatment chamber respectively; Refer to Figures 1 - 10, a screening mechanism is provided at the top of the conveyor belt 1. The screening mechanism includes a first slide rail 501 installed on the inner wall of the support frame 2. A screening seat 502 is slidably installed on the first slide rail 501. A downward material cavity 503 that penetrates up and down is formed on the screening seat 502. A number of screening groups 504 are arranged inside the downward material cavity 503. A downward material opening that penetrates up and down is formed on the support platform 3. An outlet is provided on the right side of the screening seat 502. By providing the screening mechanism, the user feeds the coal gangue through the downward material opening into the downward material cavity 503 of the screening seat 502. The coal gangue falls between adjacent screening groups 504. At this time, the coal gangue smaller than the gap between adjacent screening plates 5043 continues to fall onto the conveyor belt 1 through the downward material cavity 503 and is transported to the right through the outlet. The coal gangue that does not meet the specifications and is larger than the gap between adjacent screening plates 5043 is intercepted by the first inclined plate 5041 and the second inclined plate 5042 between adjacent groups. Through the reciprocating movement of the screening seat 502 in the front-back direction, the intercepted coal gangue is shaken out from the shaking cavity 506, so as to screen the particle size of the coal gangue and avoid the problem that coal with too large a specification cannot be blown up and fall into the gangue treatment cavity during subsequent spraying operations; Refer to Figures 1 - 10, the screening group 504 includes a first inclined plate 5041, a second inclined plate 5042 and two screening plates 5043. The first inclined plate 5041 and the second inclined plate 5042 are rotatably installed on the inner wall of the screening seat 502. The two screening plates 5043 are respectively rotatably connected to the first inclined plate 5041 and the second inclined plate 5042. The combined shape of each group of the first inclined plate 5041 and the second inclined plate 5042 is in a shape of an inverted V, and the combined shape between the first inclined plate 5041 and the second inclined plate 5042 of adjacent groups is in a shape of a V. A second slide rail 505 is installed on the inner wall of the screening seat 502. A straight notch is vertically opened on the screening plate 5043. A sliding shaft is fixedly installed on the second slide rail 505, and the sliding shaft is slidably sleeved inside the straight notch. The screening plate 5043 is slidably sleeved on the second slide rail 505. Shaking cavities 506 are opened on the front side and the rear side of the screening seat 502. The shaking cavities 506 are arranged in an inclined shape, and the bottom of the shaking cavity 506 is flush with the top of the inclined plate. When the oversized coal gangue cannot pass through the gap between the screening plates 5043, the reciprocating movement of the screening seat 502 shakes off the non-conforming coal gangue through the shaking cavity 506. The user collects it through the collection boxes arranged on both sides of the conveyor belt 1. The front sides of the first inclined plate 5041 and the second inclined plate 5042 are respectively fixedly installed with a first gear 507 and a second gear 508 through a first connecting rod. The first gear 507 and the second gear 508 are meshed with each other. The front sides of several first gears 507 are respectively fixedly installed with a first sprocket 509 through a second connecting rod. A first chain belt 510 is sleeved between several first gears 507 through the first sprocket 509. A support plate 511 is fixedly installed on the right side of the screening seat 502. Two friction wheels 512 are rotatably installed on the top of the support plate 511. A second rotating rod 513 is rotatably installed on the inner top wall of the support platform 3. A second eccentric wheel 514 is fixedly installed at the bottom of the second rotating rod 513. The second eccentric wheel 514 is located between the two friction wheels 512. By arranging the first inclined plate 5041 and the second inclined plate 5042, when the second rotating rod 513 rotates, it drives the second eccentric wheel 514 to rotate. Through the extrusion of the convex part of the second eccentric wheel 514 on the two friction wheels 512 and the limiting cooperation of the first slide rail 501, the screening seat 502 makes a reciprocating movement in the front and back directions. When one of the first gears 507 rotates, through the cooperation of the first sprocket 509 and the first chain belt 510, several first gears 507 rotate simultaneously. Through the meshing connection of the first gear 507 and the second gear 508, the second gear 508 rotates simultaneously in the opposite direction, so that the first inclined plate 5041 and the second inclined plate 5042 rotate in opposite directions simultaneously. With the cooperation of the second slide rail 505, the screening plates 5043 of the same group move in opposite directions, so that the gap between the screening plates 5043 of different groups becomes smaller, thereby adjusting the screening specification; Refer to Figures 1 - 10, a recognition mechanism is provided on the support platform 3. The recognition mechanism includes a second mounting bracket 601 which is fixedly installed on the inner top wall of the support platform 3. A sliding table 602 is slidably sleeved inside the second mounting bracket 601. An industrial camera 603 is installed at the bottom of the sliding table 602. A third rotating rod 604 is rotatably installed on the inner top wall of the support platform 3. A first spline shaft 605 is fixedly installed at the bottom of the third rotating rod 604. A first connecting rod 606 is fixedly installed at the bottom of the first spline shaft 605. A sliding rod 607 is slidably sleeved inside the first connecting rod 606. The bottom of the sliding rod 607 is flush with the bottom of the first connecting rod 606. A second connecting rod 608 is rotatably installed at the bottom of the sliding rod 607. The other end of the second connecting rod 608 is rotatably connected to the sliding table 602. By providing the recognition mechanism, when the third rotating rod 604 rotates, it drives the first spline shaft 605 and the first connecting rod 606 to rotate. The sliding rod 607 drives the second connecting rod 608 to rotate. Under the limiting cooperation of the second mounting bracket 601, the second connecting rod 608 drives the sliding table 602 to reciprocate in the axial direction of the conveyor belt 1. When the sliding table 602 drives the industrial camera 603 to move to the right, by controlling the rotation speed of the first motor 609, the moving speed of the industrial camera 603 at this time is made consistent with the moving speed of the conveyor belt 1. At this time, the industrial camera 603 and the coal gangue on the conveyor belt 1 remain relatively stationary, thereby improving the recognition effect of the industrial camera 603; Refer to Figures 1 - 10, a first motor 609 is installed on the inner top wall of the support platform 3. Second sprockets are fixedly sleeved on the surfaces of the output end of the first motor 609, the first rotating rod 409, the second rotating rod 513, and the third rotating rod 604. A second chain belt is sleeved between the output end of the first motor 609, the first rotating rod 409, the second rotating rod 513, and the third rotating rod 604 through the second sprockets. When the user starts the first motor 609, through the cooperation of the second sprockets and the second chain belt, the first rotating rod 409, the second rotating rod 513, and the third rotating rod 604 rotate simultaneously. A first spline shaft 605 is slidably sleeved with a first spline sleeve 610. The meshing of the first spline shaft 605 and the meshing of the first spline sleeve 610 are engaged with each other. A first driving block 611 is installed on the right side of the first spline sleeve 610. A second driving block 612 is fixedly installed at the top of the sliding rod 607. A driving rod 613 is sleeved between the first driving block 611 and the second driving block 612. One end of the driving rod 613 is rotatably connected to the first driving block 611, and the other end of the driving rod 613 is rotatably connected to the second driving block 612. By setting the first spline shaft 605 and the second spline sleeve 619, when the screening specification of the coal gangue in the screening mechanism becomes smaller, the first spline sleeve 610 moves downward at the same time, driving the first driving block 611 to move downward. Through the cooperation of the driving rod 613, the second driving block 612 drives the sliding rod 607 to slide inside the first connecting rod 606. At this time, the eccentric distance between the end of the sliding rod 607 and the first spline shaft 605 becomes larger, so that the reciprocating movement distance of the sliding table 602 becomes larger. When the specification of the coal gangue becomes smaller, the relative static distance between the industrial camera 603 and the coal gangue becomes larger, improving the recognition effect; Refer to Figures 1 - 10 , a first sleeve 614 is rotatably installed on the inner top wall of the support platform 3, and a second sleeve 615 is fixedly installed on the inner top wall of the support platform 3. A lead screw 616 is threadedly sleeved inside the first sleeve 614, and a limiting rod 617 is slidably sleeved inside the second sleeve 615. A lifting frame 618 is installed between the lead screw 616 and the limiting rod 617. The bottom of the lifting frame 618 is rotatably connected to the top of the first spline sleeve 610. By setting the first sleeve 614 and the second sleeve 615, when the first sleeve 614 rotates, through the threaded connection between the first sleeve 614 and the lead screw 616, and the sliding cooperation between the second sleeve 615 and the limiting rod 617, the lifting frame 618 moves downward, thereby driving the first spline sleeve 610 to move downward; Refer to Figures 1 - 10, a second spline sleeve 619 is rotatably installed on the inner side wall of the screening base 502. A second spline shaft 620 is fixedly installed on the front side of one of the second gears 508. The second spline shaft 620 is slidably sleeved inside the second spline sleeve 619. The meshing of the second spline shaft 620 and the meshing of the second spline sleeve 619 are engaged with each other. A first bevel gear 621 is fixedly sleeved on the surface of the second spline sleeve 619. A gear ring 622 and a third gear 623 are rotatably installed on the inner top wall of the screening base 502. The gear ring 622 and the third gear 623 are engaged with each other. A second bevel gear 624 is fixedly installed at the bottom of the gear ring 622. The first bevel gear 621 and the second bevel gear 624 are engaged with each other. A second motor 625 is installed on the top of the support platform 3. The output end of the second motor 625 is connected to the gear ring 622. A follower rod 626 is fixedly installed on the top of the third gear 623. Rotating wheels are fixedly sleeved on the surfaces of the follower rod 626 and the first sleeve 614. A transmission belt 627 is sleeved between the follower rod 626 and the first sleeve 614 through the rotating wheels. By providing the second spline shaft 620 and the second spline sleeve 619, when the user starts the second motor 625, it drives the second spline sleeve 619 to rotate. Under the meshing action of the second spline sleeve 619 and the second spline shaft 620, the second spline shaft 620 drives one of the second gears 508 to rotate, thereby driving one of the first gears 507 to rotate, causing several groups of first gears 507 and second gears 508 to rotate simultaneously, adjusting the screening specifications in the screening mechanism. At the same time, the second spline sleeve 619 drives the first bevel gear 621 to rotate. Through the meshing connection of the first bevel gear 621 and the second bevel gear 624, the second bevel gear 624 drives the gear ring 622 to rotate. Through the meshing connection between the gear ring 622 and the third gear 623, the third gear 623 drives the follower rod 626 to rotate. Through the cooperation of the rotating wheels and the transmission belt 627, the first sleeve 614 rotates simultaneously, so that when the user adjusts the screening specifications, the reciprocating movement distance of the industrial camera 603 changes adaptively at the same time, improving the degree of automation; A double-recognition sorting system, applicable to an ore uniform dispersion and feeding device, includes an X-ray subsystem and a camera recognition subsystem. The X-ray system and the camera recognition system are installed on the inner cavity top wall of the support frame 2.

[0023] Specifically, the working process or principle of the ore uniform distribution device and the dual-recognition sorting system is as follows: When in use, the user starts the second motor 625, which drives the second spline sleeve 619 to rotate. Under the meshing action of the second spline sleeve 619 and the second spline shaft 620, the second spline shaft 620 drives one of the second gears 508 to rotate, thereby driving one of the first gears 507 to rotate. Through the cooperation of the first sprocket 509 and the first chain belt 510, several first gears 507 rotate simultaneously, causing several groups of first gears 507 and second gears 508 to rotate simultaneously. As a result, the first inclined plate 5041 and the second inclined plate 5042 rotate in opposite directions simultaneously. With the cooperation of the second slide rail 505, the screening plates 5043 of the same group move in opposite directions, reducing the gap between the screening plates 5043 of different groups and adjusting the screening specifications in the screening mechanism. At the same time, the second spline sleeve 619 drives the first bevel gear 621 to rotate. Through the meshing connection of the first bevel gear 621 and the second bevel gear 624, the second bevel gear 624 drives the gear ring 622 to rotate. Through the meshing connection between the gear ring 622 and the third gear 623, the third gear 623 drives the follower rod 626 to rotate. Through the cooperation of the runner and the transmission belt 627, the first sleeve 614 rotates simultaneously. Through the threaded connection between the first sleeve 614 and the lead screw 616, and the sliding fit between the second sleeve 615 and the limiting rod 617, the lifting frame 618 moves downward, thereby driving the first spline sleeve 610 to move downward and driving the first driving block 611 to move downward. Through the cooperation of the driving rod 613, the second driving block 612 drives the slide rod 607 to slide inside the first connecting rod 606. At this time, the eccentric distance between the end of the slide rod 607 and the first spline shaft 605 becomes larger, so that the reciprocating movement distance of the slide table 602 becomes larger. The user feeds the coal gangue into the feeding cavity 503 of the screening seat 502 through the feeding port, and starts the first motor 609. Through the cooperation of the second sprocket and the second chain belt, the first rotating rod 409, the second rotating rod 513, and the third rotating rod 604 rotate simultaneously. When the second rotating rod 513 rotates, it drives the second eccentric wheel 514 to rotate. Through the extrusion of the convex part of the second eccentric wheel 514 on the two friction wheels 512 and the limiting cooperation of the first slide rail 501, the screening seat 502 makes a reciprocating movement in the front-back direction. At this time, the coal gangue smaller than the gap between adjacent screening plates 5043 continues to fall through the feeding cavity 503 onto the conveyor belt 1 and is transported to the right through the discharge port. The coal gangue that does not meet the specifications and is larger than the gap between adjacent screening plates 5043 is intercepted by the first inclined plate 5041 and the second inclined plate 5042 between adjacent groups. Through the reciprocating movement of the screening seat 502 in the front-back direction, the intercepted coal gangue is shaken out from the shaking cavity 506, thereby screening the particle size of the coal gangue. When the coal gangue on the conveyor belt 1 is transported to the right, the first rotating rod 409 rotates,Drive the first eccentric wheel 410 to rotate. The convex part of the first eccentric wheel 410 presses against the rear inner wall of the square frame 405, causing the square frame 405 to drive the second reciprocating rod 403 to press against the first reciprocating rod 402, so that the second reciprocating rod 403, the first reciprocating rod 402 and the third reciprocating rod 404 move backward, thereby driving the uniform dispersion seat 406 and the partition plate 408 to move backward. When the convex part of the first eccentric wheel 410 presses against the left inner wall of the square frame 405, the second reciprocating rod 403 slides inside the first reciprocating rod 402. At this time, the first reciprocating rod 402 remains stationary, and the second reciprocating rod 403 drives the third reciprocating rod 404, the uniform dispersion seat 406 and the partition plate 408 to move leftward. Similarly, when the convex part of the first eccentric wheel 410 presses against the front inner wall and the right inner wall of the square frame 405, the uniform dispersion seat 406 and the partition plate 408 move forward and rightward respectively, so that the uniform dispersion seat 406 and the partition plate 408 reciprocate above the conveyor belt 1 in a square trajectory, thereby evenly spreading and paving the coal gangue on the conveyor belt 1. When the third rotating rod 604 rotates, it drives the first spline shaft 605 and the first connecting rod 606 to rotate. The sliding rod 607 drives the second connecting rod 608 to rotate. Under the limit cooperation of the second mounting bracket 601, the second connecting rod 608 drives the sliding table 602 to reciprocate in the axial direction of the conveyor belt 1. When the sliding table 602 drives the industrial camera 603 to move to the right, by controlling the rotation speed of the first motor 609, the moving speed of the industrial camera 603 is made consistent with the moving speed of the conveyor belt 1 at this time. At this time, the industrial camera 603 and the coal gangue on the conveyor belt 1 remain relatively stationary, thereby improving the recognition effect of the industrial camera 603. After the precise recognition by the industrial camera 603 and the X-ray, at the end of the conveyor belt 1, through the compressed air blowing operation carried out by the air storage tank at the bottom of the conveyor belt 1, the coal and gangue are precisely blown into the coal treatment chamber and the gangue treatment chamber respectively.,
