Description

Technical Field

[0001] The present invention relates to the technical field of ore sorting, and in particular to an ore uniform distribution device and a double-identification sorting system. Background Art

[0002] Ore sorting is one of the core links in mineral processing. It refers to the process of separating valuable mineral components in the mined raw ore from waste rock or other impurities through physical, chemical or biological methods. Under this premise, people have invented the innovative application of photoelectric sorting and waste disposal technology. Its core lies in the precise identification through industrial cameras, and then controlling the compressed air from the gas tank at the end of the conveyor belt to spray. The weight difference between coal and gangue makes the coal and gangue fall into different processing chambers after being sprayed.

[0003] In the existing technology, during the process of coal gangue sorting, the coal gangue often stacks up on each other. As a result, when the coal gangue passes under the industrial camera, some of the coal gangue stacks up on each other, causing the industrial camera to be unable to accurately identify it, thereby affecting the accuracy of the gas tank's blowing operation.

DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0035] Reference Figures 1-10The present invention provides a technical solution: an ore uniform distribution device and a double identification and sorting system, comprising 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 distribution mechanism is provided on the support platform 3, and the uniform distribution mechanism includes a first mounting frame 401 and a third reciprocating rod 404, the first mounting frame 401 is fixedly mounted on the inner top wall of the support platform 3, the first mounting frame 401 is internally slidingly sleeved with a first reciprocating rod 402, the first reciprocating rod 402 is internally slidingly sleeved with a second reciprocating rod 403, the third reciprocating rod 404 is mounted on one end of the second reciprocating rod 403 by a bolt, the other end of the second reciprocating rod 403 is integrally formed with a square frame 405, the third reciprocating rod 404 The bottom of the support 3 is provided with a scattering seat 406 by bolts and a mounting plate, and a through cavity 407 is provided on the scattering seat 406, which is passed through to the left and right. The inner wall of the through cavity 407 on the left is chamfered to facilitate the entry of coal gangue into the through cavity 407. A plurality of partitions 408 are provided inside the through cavity 407, and the plurality of partitions 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, and a first eccentric wheel 410 is fixedly installed on the bottom of the first rotating rod 409. The first eccentric wheel 410 is located inside the square frame 405, and the center of the first eccentric wheel 410 is intersected with the central axis of the square frame 405. By setting a scattering distribution mechanism, when the coal gangue on the conveyor belt 1 is transported to the right, the first rotating rod 409 is rotated. The rod 409 rotates, driving the first eccentric wheel 410 to rotate. The raised portion 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, causing the second reciprocating rod 403, the first reciprocating rod 402 and the third reciprocating rod 404 to move backward, thereby driving the evenly distributed seat 406 and the partition 408 to move backward. When the raised portion 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 evenly distributed seat 406 and the partition 408 to move left. Similarly, when the raised portion of the first eccentric wheel 410 squeezes the front inner wall and the right inner wall of the square frame 405, the scattering seat 406 and the partition 408 move forward and rightward respectively, so that the scattering seat 406 and the partition 408 move back and forth above the conveyor belt 1 in a square trajectory, thereby evenly spreading and flattening the coal gangue on the conveyor belt 1, avoiding the subsequent accumulation of coal gangue, which causes the industrial camera 603 to be unable to accurately identify the problem. The flattened coal gangue continues to be transported to the right on the conveyor belt 1. After accurate identification by the industrial camera 603 and X-rays, the compressed blowing operation is performed at the end of the conveyor belt 1 through the gas tank at the bottom of the conveyor belt 1, so that the coal and gangue are accurately blown into the coal processing chamber and the gangue processing chamber respectively;

[0036] Reference Figures 1-10 A screening mechanism is provided on the top of the conveyor belt 1, and the screening mechanism includes a first slide rail 501, which is installed on the inner wall of the support frame 2. A screening seat 502 is slidably installed on the first slide rail 501, and a vertically through-through feeding cavity 503 is provided on the screening seat 502. A plurality of screening groups 504 are provided inside the feeding cavity 503. A vertically through-through feeding port is provided on the support platform 3, and a discharge port is provided on the right side of the screening seat 502. By setting the screening mechanism, the user passes the coal gangue into the feeding cavity 503 of the screening seat 502 through the feeding port, and the coal gangue falls into the adjacent screening group 5 04, at this time, the gangue smaller than the gap between the adjacent screening plates 5043 continues to fall through the discharge chamber 503 to the conveyor belt 1, and is transported to the right through the discharge port. The gangue that does not meet the specifications and is larger than the gap between the adjacent screening plates 5043 is intercepted by the first inclined plate 5041 and the second inclined plate 5042 between the adjacent groups. The screening seat 502 moves back and forth in the front and back directions, so that the intercepted gangue is shaken out from the shaking-off chamber 506, thereby screening the particle size of the gangue, avoiding the problem that the coal with too large specifications cannot be blown up and falls into the gangue processing chamber in the subsequent blowing operation;

[0037] Reference Figures 1-10The 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 mounted on the inner wall of the screening seat 502. The two screening plates 5043 are rotatably connected to the first inclined plate 5041 and the second inclined plate 5042 respectively. The shape of the combination of the first inclined plate 5041 and the second inclined plate 5042 of each group is an eight-shaped shape. The shape of the combination between the first inclined plate 5041 and the second inclined plate 5042 of the adjacent groups is an inverted eight-shaped shape. The inner wall of the screening seat 502 is installed with a second slide rail 505. A straight slot is vertically opened on the screening plate 5043. A sliding shaft is fixedly mounted on the second slide rail 505, and the sliding shaft is slidably sleeved on the straight slot Inside, the screening plate 5043 is slidably mounted on the second slide rail 505, and a shaking-off cavity 506 is provided on the front and rear sides of the screening seat 502. The shaking-off cavity 506 is arranged in an inclined shape, and the bottom of the shaking-off cavity 506 is flush with the top of the inclined plate. When the coal gangue that is too large cannot pass through the gap between the screening plates 5043, the reciprocating movement of the screening seat 502 will shake off the coal gangue that does not meet the specifications through the shaking-off cavity 506. The user collects it by setting a collection box on both sides of the conveyor belt 1. The front sides of the first inclined plate 5041 and the second inclined plate 5042 are fixedly installed with a first gear 507 and a second gear 508 through a first connecting rod respectively. The first gear 507 and the second gear 508 are meshed with each other, and several first gears 507 are engaged with each other. The front side is fixedly installed with a first sprocket 509 through a second connecting rod, and 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, and 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, and a second eccentric wheel 514 is fixedly installed on 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, the second eccentric wheel 514 is driven to rotate, and the two friction wheels 512 are squeezed by the raised portion of the second eccentric wheel 514. The first gear 507 rotates in a forward and backward direction, and the first gear 507 rotates in a forward and backward direction, and the first gear 507 rotates in a forward and backward direction, and the first gear 507 rotates in a forward and backward direction, and the first gear 507 rotates in a forward and backward direction, and the first gear 507 rotates in a forward and backward direction, and the second gear 508 rotates in a reverse direction, and the first and second gears 508 rotate in a reverse direction, respectively. The first and second inclined plates 5041 and 5042 rotate in reverse directions, respectively. The second slide rail 505 cooperates with the screening plates 5043 in the same group to move in reverse directions, so that the gaps between the screening plates 5043 in different groups become smaller, thereby adjusting the screening specifications.

[0038] Reference Figures 1-10 , an identification mechanism is provided on the support platform 3, and the identification mechanism includes a second mounting frame 601, the second mounting frame 601 is fixedly mounted on the inner top wall of the support platform 3, the internal sliding sleeve of the second mounting frame 601 is provided with a slide 602, the bottom of the slide 602 is provided with an industrial camera 603, the inner top wall of the support platform 3 is rotatably mounted with a third rotating rod 604, the bottom of the third rotating rod 604 is fixedly mounted with a first spline shaft 605, the bottom of the first spline shaft 605 is fixedly mounted with a first connecting rod 606, the internal sliding sleeve of the first connecting rod 606 is provided with a sliding rod 607, the bottom of the sliding rod 607 is flush with the bottom of the first connecting rod 606, the bottom of the sliding rod 607 is rotatably mounted with a second connecting rod 608, and the other end of the second connecting rod 608 The end is rotatably connected to the slide 602. By setting an identification mechanism, when the third rotating rod 604 rotates, it drives the first spline shaft 605 and the first connecting rod 606 to rotate, and the slide 607 drives the second connecting rod 608 to rotate. Under the limit cooperation of the second mounting frame 601, the second connecting rod 608 drives the slide 602 to reciprocate in the axial direction of the conveyor belt 1. When the slide 602 drives the industrial camera 603 to move to the right, the speed of the first motor 609 is controlled to make the moving speed of the industrial camera 603 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 still, thereby improving the recognition effect of the industrial camera 603.

[0039] Reference Figures 1-10, a first motor 609 is installed on the inner top wall of the support platform 3, and a second sprocket is fixedly sleeved on the surface 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, and a second chain belt is provided 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 sprocket sleeve. When the user starts the first motor 609, the first rotating rod 409, the second rotating rod 513 and the third rotating rod 604 rotate simultaneously through the cooperation of the second sprocket and the second chain belt, and a first spline sleeve is slidingly sleeved on the surface of the first spline shaft 605, and the meshing of the first spline shaft 605 and the meshing of the first spline sleeve 610 are engaged. A first driving block 611 is installed on the right side of the first spline sleeve 610, and a second driving block 612 is fixedly installed on 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 specifications of the coal gangue in the screening mechanism become smaller, the first spline sleeve 610 is moved 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, thereby increasing the reciprocating distance of the slide 602. When the specifications of the coal gangue become smaller, the relatively static distance between the industrial camera 603 and the coal gangue becomes larger, thereby improving the recognition effect.

[0040] Reference Figures 1-10 , a first sleeve 614 is rotatably mounted on the inner top wall of the support platform 3, and a second sleeve 615 is fixedly mounted on the inner top wall of the support platform 3, an internal thread sleeve of the first sleeve 614 is provided with a screw rod 616, and an internal sliding sleeve of the second sleeve 615 is provided with a limit rod 617, a lifting frame 618 is installed between the screw rod 616 and the limit rod 617, and the bottom of the lifting frame 618 is rotatably connected to the top of the first spline sleeve 610. By arranging the first sleeve 614 and the second sleeve 615, when the first sleeve 614 rotates, the lifting frame 618 moves downward through the threaded connection between the first sleeve 614 and the screw rod 616, and the sliding cooperation between the second sleeve 615 and the limit rod 617, thereby driving the first spline sleeve 610 to move downward;

[0041] Reference Figures 1-10The inner wall of the screening seat 502 is rotatably mounted with a second spline sleeve 619, and a second spline shaft 620 is fixedly mounted 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, and the meshing of the second spline shaft 620 and the meshing of the second spline sleeve 619 are meshed. The surface of the second spline sleeve 619 is fixedly sleeved with a first bevel gear 621, and the inner top wall of the screening seat 502 is rotatably mounted with a ring gear 622 and a third gear 623. The ring gear 622 and the third gear 623 The second bevel gear 624 is fixedly installed at the bottom of the gear ring 622, and the first bevel gear 621 and the second bevel gear 624 are meshed. A second motor 625 is installed on the top of the support platform 3, and 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. The surfaces of the follower rod 626 and the first sleeve 614 are fixedly sleeved with a rotating wheel. A transmission belt 627 is provided between the follower rod 626 and the first sleeve 614 through the rotating wheel sleeve. By setting a second spline shaft 620 and the second spline sleeve 619, the user starts the second motor 625 to drive the second spline sleeve 619 to rotate. Through 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, so that several groups of first gears 507 and second gears 508 rotate simultaneously, and the screening specifications in the screening mechanism are adjusted. At the same time, the second spline sleeve 619 drives the first bevel gear 621 to rotate. Through the meshing connection between the first bevel gear 621 and the second bevel gear 624, the second bevel gear 624 drives the ring gear 622 to rotate. Through the meshing connection between the ring gear 622 and the third gear 623, the third gear 623 drives the follower rod 626 to rotate. Through the cooperation of the rotating wheel and the transmission belt 627, the first sleeve 614 rotates simultaneously. Therefore, when the user adjusts the screening specifications, the reciprocating movement distance of the industrial camera 603 is adaptively changed at the same time, thereby improving the degree of automation;

[0042] A dual identification and sorting system is suitable for an ore uniform distribution device, comprising an X-ray subsystem and a camera identification subsystem, which are installed on the top wall of the inner cavity of a support frame 2.

[0043] Specifically, the working process or working principle of the ore uniform distribution device and the dual identification and sorting system is as follows: when in use, the user starts the second motor 625 to drive the second spline sleeve 619 to rotate, and through 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, and through the cooperation of the first sprocket 509 and the first chain belt 510, several first gears 507 rotate at the same time, so that several groups of first gears 507 and second gears 508 rotate at the same time, thereby causing the first inclined plate 5041 and the second inclined plate 5042 to rotate in opposite directions at the same time, and under the cooperation of the second slide rail 505 , making the screening plates 5043 of the same group move in opposite directions, making the gaps between the screening plates 5043 of different groups smaller, 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, and the meshing connection between the first bevel gear 621 and the second bevel gear 624 makes the second bevel gear 624 drive the ring gear 622 to rotate, and the meshing connection between the ring gear 622 and the third gear 623 makes the third gear 623 drive the follower rod 626 to rotate, and the cooperation between the rotating wheel and the transmission belt 627 makes the first sleeve 614 rotate at the same time, through the threaded connection between the first sleeve 614 and the screw rod 616, and the sliding connection between the second sleeve 615 and the limit rod 617. When the first drive block 611 is moved downward, the lifting frame 618 is moved downward, thereby driving the first spline sleeve 610 to move downward, driving the first driving block 611 to move downward, and 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, thereby increasing the reciprocating distance of the slide 602. The user passes the coal gangue into the discharge cavity 503 of the screening seat 502 through the discharge port, starts the first motor 609, and 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 at the same time. When the second rotating rod 513 rotates, it drives the second eccentric wheel 514 to The second eccentric wheel 514 is rotated, and the two friction wheels 512 are squeezed by the raised part of the second eccentric wheel 514, and the first slide rail 501 is limited to cooperate, so that the screening seat 502 reciprocates in the front and rear directions. At this time, the coal gangue smaller than the gap between the adjacent screening plates 5043 continues to fall onto the conveyor belt 1 through the discharge cavity 503 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 the adjacent screening plates 5043 is intercepted by the first inclined plate 5041 and the second inclined plate 5042 between the adjacent groups. The screening seat 502 reciprocates in the front and rear directions, so that the intercepted coal gangue is shaken out from the shaking-off cavity 506, thereby screening the coal gangue for particle size. When the coal gangue on the conveyor belt 1 is transported to the right, the first rotating rod 409 rotates.The first eccentric wheel 410 is driven to rotate, and the raised portion of the first eccentric wheel 410 squeezes the rear inner wall of the square frame 405, so that the square frame 405 drives 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 distribution seat 406 and the partition 408 to move backward. When the raised portion 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. The second reciprocating rod 403 drives the third reciprocating rod 404, the evenly distributed seat 406 and the partition 408 to move to the left. Similarly, when the raised portion of the first eccentric wheel 410 squeezes the front inner wall and the right inner wall of the square frame 405, the evenly distributed seat 406 and the partition 408 move forward and right respectively, so that the evenly distributed seat 406 and the partition 408 move along a square trajectory on the conveying 1 and 1. The third rotating rod 604 rotates, driving the first spline shaft 605 and the first connecting rod 606 to rotate, and the sliding rod 607 drives the second connecting rod 608 to rotate. Under the limited cooperation of the second mounting frame 601, the second connecting rod 608 drives the slide 602 to move back and forth in the axial direction of the conveyor belt 1. When the slide 602 drives the industrial camera 603 to move to the right, the speed of the first motor 609 is controlled so that the movement speed of the industrial camera 603 is consistent with the movement 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. After accurate recognition by the industrial camera 603 and X-ray, the compressed blowing operation is performed at the end of the conveyor belt 1 through the gas storage tank at the bottom of the conveyor belt 1, so that the coal and gangue are accurately blown into the coal processing chamber and the gangue processing chamber respectively. ,
