Description

Technical Field

[0001] The utility model relates to the technical field of ore sorting, in particular to a belt conveyor. Background Art

[0002] The ore pile needs to be transported by conveyor belt before crushing, because the ore pile contains some iron blocks. If they enter the crushing equipment, the iron blocks will damage the equipment. The iron blocks need to be removed during the transportation process.

[0003] The prior art is to set an iron removal device above the conveyor belt to suck out the iron blocks during the conveying process. This method has certain problems. Many iron blocks are covered by ore at the bottom of the conveyor belt. The iron removal device is at a fixed height and cannot magnetically attract the iron blocks at the bottom. Moreover, if weakly magnetic metals such as high manganese steel, stainless steel, and aluminum alloy are mixed in the ore pile, it is difficult for the iron removal device to remove them. After the iron removal device magnetically attracts the iron blocks, it cannot remove the iron blocks. When there are many iron blocks on the iron removal device, the machine can only be stopped to manually remove the iron blocks on the surface of the iron removal device. Frequent shutdowns to remove the iron blocks will affect production efficiency. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example

[0031] like Figure 1 , 2 As shown in Figures 3 and 8, a belt conveyor includes a conveyor belt and an iron removal device 3 arranged at the upper end of the conveyor belt, the conveyor belt includes a roller 1 and a conveyor belt 101, the roller 1 is internally recessed, the conveyor belt 101 and the roller 1 are closely attached to the recessed positions, the middle part of the conveyor belt is recessed, and the ore will accumulate in the recessed place, which can not only narrow the detection range, the ore will not be scattered on the conveyor belt, but also make the ore transportation process more stable.

[0032] like Figure 1 , 2 As shown in Figures 3 and 8, a baffle bar 2 is provided above the conveyor belt. The baffle bar 2 is provided at the front end of the conveyor belt 101 in the moving direction. A plurality of detection elements Ⅰ21 are provided on the baffle bar 2. The detection element Ⅰ21 is a metal detector. The baffle bar 2 breaks up the ore accumulated on the conveyor belt to make it thinner, which is convenient for detecting iron blocks. At the same time, it prevents the accumulation of ore from causing uneven force on the conveyor belt, thereby causing damage to the conveyor belt. When the metal detector detects an iron block, it transmits a signal to the iron removal device 3 at the rear.

[0033] like Figure 1 , 4As shown in Figures 5, 6, 7 and 8, the iron removal device 3 includes a rotating shaft 31, a belt 33 and an electromagnetic coil 32. The belt 33 is arranged on the outside of at least two rotating shafts 31, and the electromagnetic coil 32 is arranged in the belt 33 and does not contact the belt. It is connected to the protrusions on both sides through an additional supporting structure. The iron removal device 3 and the conveyor belt 101 are arranged perpendicular to each other. A plurality of limit plates 331 are arranged on the belt 33. When the electromagnetic coil 32 is energized, the electromagnetic coil 32 has magnetism to absorb the iron blocks on the surface of the conveyor belt to the belt 33, and the belt 33 continuously transports. When the belt 33 transports the iron blocks to the position of the rotating shaft 31, the attraction between the electromagnetic coil 32 and the iron blocks is reduced, and the iron blocks are removed from the belt 33. When the iron block is magnetically attracted to the belt 33, the limit plate 331 pushes the iron block away from the electromagnetic coil 32. The limit plate 331 prevents the electromagnetic coil 32 from attracting the iron block to the belt 33 when the magnetic force is large, so that the iron block will not be transmitted away from the electromagnetic coil 32 during the transportation of the belt 33. A protrusion 34 is arranged at one end of the rotating shaft 31, and a driving member is arranged at the other end. The driving member is a motor 35. The motor 35 drives the rotating shaft 31 to rotate, and then drives the belt 33 to move. A connecting seat Ⅰ4 is arranged on the protrusion 34, and a lifting member Ⅰ is arranged below the connecting seat Ⅰ4. The lifting member Ⅰ is a cylinder Ⅰ42. A support box Ⅰ41 is arranged at the outer end of the cylinder Ⅰ42. The connecting seat Ⅰ4 can slide The motor 35 is provided with a supporting assembly, and a lifting member II is provided below the supporting assembly, and the lifting member II is a cylinder II56, and a supporting box II55 is provided at the outer end of the cylinder II56, and the supporting assembly includes an arc-shaped buckle plate I5 and a buckle plate II52, and connecting plates I51 are provided on both sides of the buckle plate I5, and connecting plates II53 are provided on both sides of the buckle plate II52, and a plurality of threaded holes I511 are provided on the connecting plate I51, and a plurality of threaded holes II531 are provided on the connecting plate II53, and the buckle plate I5 and the buckle plate II52 are provided with a supporting assembly. The buckle plate II 52 supports the motor 35, the threaded hole I 511 is aligned with the threaded hole II 531, and the bolt is screwed in to fix the motor 35. The support assembly is slidably arranged in the support box II 55. A connecting column 54 is arranged below the buckle plate II 52, and the connecting column 54 is connected to the cylinder II 56. When the cylinder II 56 rises, the cylinder II 56 drives the connecting column 54 to rise, and the buckle plate I 5 and the buckle plate II 52 drive the motor 35 to rise synchronously. When the cylinder I 42 and the cylinder II 56 cooperate, the entire iron removal device 3 rises and falls synchronously. When an iron block is detected, the iron removal device 3 can be lowered to suck up the iron block, so that the magnetic attraction inside the iron removal device 3 can be physically adjusted to avoid the situation where weak magnetic metal cannot be sucked up.

[0034] like Figure 8As shown, a collection box 6 is arranged between the support box Ⅰ41 and the support box Ⅱ55. The collection box 6 is arranged opposite to the belt 33. The iron blocks are transported on the belt 33. When the iron blocks are away from the electromagnetic coil 32, they will fall from the belt 33. The collection box 6 is arranged at the falling position of the iron blocks to collect the fallen iron blocks to prevent the iron blocks from affecting the surrounding environment. At the same time, a rotating wheel 61 is arranged under the collection box 6. After collecting the iron blocks for a period of time, the collection box 6 can be pushed to transport the iron blocks to facilitate the subsequent recycling by the workers.

[0035] like Figure 1 , 8 As shown, a detection rod 7 is also provided above the conveyor belt. The detection rod 7 is arranged at a position far away from the iron removal device 3. A plurality of detection elements II 71 are provided on the detection rod 7. The detection element II 71 is also a metal detector. It is inevitable that omissions will occur during the front-end detection and iron removal process. The detection rod 7 is provided before the ore is about to enter the crusher to perform the final detection on the ore. When an iron block is detected, the conveyor belt is stopped and the workers remove the iron block.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
