[0036] Please refer to Figure 1-9 。

[0037] The present invention provides a technical solution for a coal iron removal device: A coal iron removal device includes a conveyor 1 composed of a conveyor belt 101, a main shaft 102, and a motor 103. The main shaft 102 is arranged at both ends of the conveyor belt 101, and the output end of the motor 103 drives the conveyor belt 101 to rotate by being fixedly connected to one side of the main shaft 102. It further includes: A coarse iron removal assembly 2 composed of a support frame 201 fixedly arranged on one side of the conveyor belt 101, a magnetic conveyor belt 202 arranged at one end of the support frame 201, and a collection box 203 arranged on one side of the conveyor belt 101, which adsorbs large particle iron blocks existing in the coal through the magnetic conveyor belt 202 and collects them through the collection box 203; A lifting assembly 3 composed of a fixed seat 301 arranged at the center of the conveyor belt 101 and a moving bar 302 slidably arranged on the upper end of the fixed seat 301, which is used to intermittently lift the conveyor belt 101; A linkage assembly 4 composed of a first conveyor belt 401 and a second conveyor belt 402 arranged on one side of the conveyor belt 101, a rotating disk 405, and a moving frame 406, which enables the conveyor belt 101 to drive the rotation of the magnetic conveyor belt 202 and the reciprocating up and down movement of the moving bar 302 during rotation; A fine iron removal assembly 5 composed of a support seat 501 arranged on one side of the conveyor belt 101, a first separation roller 503 and a second separation roller 504 rotatably arranged on the support seat 501, and a separation sheet 505 arranged between them, which is used to collect fine particle iron blocks existing in the coal and collect them into the collection box 203; A transmission assembly 6 composed of a transmission rod 601 arranged at one end of a first rotating shaft 2021 and a third conveyor belt 604, which is used to drive the opposite rotation of the first separation roller 503 and the second separation roller 504 through the rotation of the magnetic conveyor belt 202.

[0038] In an embodiment, a first rotating shaft 2021 and a second rotating shaft 2022 are rotatably arranged at the bottom of one end of the support frame 201. The magnetic conveyor belt 202 is sleeved between the first rotating shaft 2021 and the second rotating shaft 2022. A scraping plate 2031 is fixedly arranged at one end of the collection box 203.

[0039] With such a design, through the continuous rotation of the magnetic conveyor belt 202, the coarse iron in the coal on the conveyor belt 101 is adsorbed and collected, and then the iron on the magnetic conveyor belt 202 is scraped off by the scraping plate 2031 and dropped into the collection box 203.

[0040] In an embodiment, two fixing piles 3011 are fixedly arranged on one side surface of the fixed seat 301. One end of the first conveyor belt 401 is sleeved on the outer side wall of the first rotating shaft 2021. The other end of the first conveyor belt 401 is provided with a third rotating shaft 4011. One end of the third rotating shaft 4011 is rotatably arranged on the side wall of the support frame 201. A first bevel gear 403 is fixedly arranged on one side surface of the third rotating shaft 4011;

[0041] One end of the second conveyor belt 402 is sleeved on one of the main shafts 102. The other end of the second conveyor belt 402 is sleeved with a fourth rotating shaft 4021. A second bevel gear 404 meshing with the first bevel gear 403 is fixedly arranged on one side surface of the fourth rotating shaft 4021;

[0042] A rotating disk 405 is fixedly arranged on the other side surface of the fourth rotating shaft 4021. A moving column 4051 is fixedly arranged near the edge of one side surface of the rotating disk 405. A moving frame 406 is fixedly arranged at one end of the moving bar 302. The upper and lower ends of the moving frame 406 are slidably arranged in the fixing pile 3011. An activity slot 4061 adapted to the moving column 4051 is arranged at the center of the moving frame 406.

[0043] In this design, when the motor 103 starts to drive the main shaft 102 to rotate, the conveyor belt 101 starts to transport coal. At this time, the main shaft 102 will drive the transmission belt 2 402 to rotate, and then drive the rotating shaft 4 4021 to rotate. The rotation of the rotating shaft 4021 will drive the bevel gear 2 404 to rotate. The rotation of the bevel gear 2 404 drives the bevel gear 1 403 to rotate, thereby driving the rotating shaft 3 4011 and the transmission belt 1 401 to rotate, and then driving the rotating shaft 1 2021 and the magnetic conveyor belt 202 to rotate, and the magnetic conveyor belt 202 absorbs the iron block. At the same time, the rotating shaft 4021 will drive the rotating disk 405 to rotate. The rotation of the rotating disk 405 will cause the moving column 4051 thereon to start rotating. When the moving column 4051 starts rotating, it will drive the moving frame 406 to move up and down, and then drive the moving bar 302 to move up and down. When the moving bar 302 moves upward, it will contact the conveyor belt 101 and make the center of the conveyor belt 101 begin to fluctuate up and down, thereby causing the coal on it to shake. The two sides of the conveyor belt 101 are arranged with slopes to prevent the coal from shaking out of the conveyor 1.

[0044] In one embodiment, the other ends of the separation roller 1 503 and the separation roller 2 504 are rotatably arranged on one side of the collection box 203, a protection frame 502 is arranged on the upper end of the support seat 501, and magnetic bars staggered with each other are arranged on the separation roller 1 503 and the separation roller 2 504. The two sides of the separation sheet 505 are arranged at an angle, and a groove matching the magnetic bar is provided on the separation sheet 505. A rubber strip 5051 is fixedly provided on the side wall of the groove. A moving groove 5052 is provided at the center of the separation sheet 505, and a guide strip 507 arranged in a slope is fixedly provided inside the moving groove 5052.

[0045] A delivery pipe 506 connected to the collection box 203 is fixedly provided at one end of the separation sheet 505, and the delivery pipe 506 is connected to the moving groove 5052;

[0046] A bevel gear 3 602 is fixedly provided at one end of the transmission rod 601, a bevel gear 4 603 meshing with the bevel gear 3 602 is fixedly provided at one end of the separation roller 2 504, and one end of the transmission belt 3 604 is sleeved on the outer side wall of one end of the separation roller 2 504;

[0047] The other end of the transmission belt three 604 is provided with a rotating shaft five 6041, on which a transmission gear one 605 is fixedly provided. One end of the separation roller one 503 is provided with a transmission gear two 606 matched with the transmission gear one 605. One end of the rotating shaft five 6041 is rotatably connected to the protective frame 502.

[0048] With such a design, when the rotating shaft one 2021 rotates, it will drive the transmission rod 601 to rotate. The rotation of the transmission rod 601 will drive the separation roller two 504 to rotate through the meshing of the third bevel gear 602 and the fourth bevel gear 603. Thus, it will drive the rotating shaft five 6041 to rotate through the third transmission belt 604. The rotation of the rotating shaft five 6041 causes the first transmission gear 605 to drive the second transmission gear 606 to rotate, so that the separation roller one 503 and the separation roller two 504 rotate towards each other. When the separation roller one 503 and the separation roller two 504 start to rotate, they will continuously insert into the coal conveyed above the conveyor belt 101. The magnetic rods on them will adsorb the smaller iron substances in the coal. When they rotate to the position of the upper separation piece 505, the separation piece 505 will comb the iron substances on the magnetic rods through the rubber strip 5051. After the iron substances are combed off, they will slide into the moving groove 5052 at the center of the separation piece 505 due to their own gravity, and thus enter the collection box 203 through the guiding strip 507 and the conveying pipe 506.

[0049] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
