Description

Technical Field

[0001] This utility model relates to the field of ore detection, and more specifically, to an ore thickness detection device. Background Technology

[0002] During the mining and processing of ore, the raw ore often contains metallic impurities (such as cutting teeth, iron blocks, etc.). In order to prevent the metallic impurities from damaging the subsequent crushing equipment, they need to be detected and sorted during the conveying process.

[0003] In the prior art, Chinese utility model patent with publication number CN220751063U discloses a metal shape detection device. This prior art forms a detection space by using a first coil and a second coil arranged opposite each other, and uses a conveyor belt to carry ore through the space to detect the shape, length and thickness of the metal. However, in actual use, although a guide baffle is provided, the guide baffle can only passively limit and guide the ore on the conveyor belt. Since the ore often stacks and is unevenly distributed and locally dense during the feeding process, when the stacked ore enters the detection space, the induction signals generated by multiple metals will overlap, causing the control system to misjudge it as a single large piece of metal, which seriously affects the accuracy of shape detection. In addition, the stacked ore can also cause the metal in the lower layer to be blocked, resulting in missed detection. In view of this, we propose an ore thickness detection device to solve the above problems. Utility Model Content

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A device for detecting ore thickness includes a conveyor body 1 and an ore detection unit 2 disposed on the upper side of the conveyor body 1. An adjustment mechanism 3 is disposed on the upper side of the conveyor body 1, a guide mechanism 4 is disposed on the lower side of the adjustment mechanism 3, a flattening mechanism 5 is disposed on the upper side of the conveyor body 1, and a transmission mechanism 6 is disposed on the outside of the conveyor body 1. The tiling mechanism 5 includes a first mounting frame 51, which is fixedly mounted on the upper surface of the frame of the conveyor body 1. The first mounting frame 51 has a cavity 52 extending out of the lower surface of the cross plate. A reciprocating screw 53 is rotatably connected inside the cavity 52. ​​A reciprocating screw sleeve 54 is provided outside the reciprocating screw 53. The reciprocating screw sleeve 54 is slidably connected to the bottom wall of the cavity 52. ​​The reciprocating screw sleeve 54 cooperates with the helical groove on the surface of the reciprocating screw 53 through an internal guide element, so that when the reciprocating screw 53 rotates, the reciprocating screw sleeve 54 can reciprocate along the axial direction of the reciprocating screw 53.

[0021] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a support shaft 9 is rotatably connected inside the cavity 52. ​​A swing plate 10 is fixedly sleeved on the outside of the support shaft 9. Two connecting plates 11 are slidably sleeved inside the swing plate 10. A transverse plate 14 is hinged to the end of each connecting plate 11 away from the swing plate 10. A transmission gear 12 is also fixedly sleeved on the outside of the support shaft 9. A toothed plate 13 is meshed with the outside of the transmission gear 12.

[0022] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, two movable plates 55 are provided on the lower side of the horizontal plate of the first mounting bracket 51. Both movable plates 55 can slide into the cavity 52 and are fixedly connected to the two horizontal sliding plates 14 respectively. Several levers 56 are fixedly connected to the lower surface of each of the two movable plates 55. The rotation of the reciprocating screw 53 can drive the reciprocating screw sleeve 54 to slide inside the cavity 52. ​​The movement of the reciprocating screw sleeve 54 can drive the movement of the gear plate 13. The movement of the gear plate 13 can drive the rotation of the transmission gear 12. The rotation of the support shaft 9 will drive the rotation of the swing plate 10, which in turn will drive the swing of the two connecting plates 11, ultimately driving the two transverse plates 14 to reciprocate. The reciprocating movement of the transverse plates 14 will drive the reciprocating movement of the moving plate 55, which in turn will drive the movement of the lever 56. At this time, the lever 56 can force the ore conveyed on the surface of the conveyor body 1 to move, thereby effectively avoiding the stacking of ore and local accumulation.

[0023] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the transmission mechanism 6 includes a first transmission shaft 61, which is rotatably connected to the surface of the conveyor body 1 and rotatably penetrates into the interior of the conveyor body 1. The first transmission shaft 61 is fixedly connected to the shaft of the conveyor belt inside the conveyor body 1, so that the first transmission shaft 61 can be driven to rotate during the operation of the conveyor belt. A second transmission shaft 62 is rotatably connected to the surface of the first mounting frame 51. The second transmission shaft 62 rotatably penetrates into the interior of the first mounting frame 51 and is fixedly connected to the reciprocating screw 53. Synchronous pulleys 63 are fixedly sleeved on the outside of both the first transmission shaft 61 and the second transmission shaft 62. Synchronous belts 64 are sleeved on the outside of the two synchronous pulleys 63. The rotation of the first transmission shaft 61 and the cooperation between the two synchronous pulleys 63 and the synchronous belt 64 can drive the second transmission shaft 62 to rotate. The rotation of the second transmission shaft 62 can drive the rotation of the reciprocating screw 53.

[0024] In the above embodiments, the ore detection unit 2 includes a mounting bracket and a control system. The mounting bracket is provided with a first coil and a second coil, which are arranged opposite to each other and form a detection space between them. The first coil is used to emit electromagnetic waves to the second coil to induce a current in the second coil. The first coil, the second coil, and the transmission components are all connected to the control system. The control system is used to detect changes in the induced current generated by the second coil to detect the shape, length, and thickness of the metal in the object to be detected. For details, please refer to the prior art with announcement number CN220751063U. Since these are all known technical means in the art, they will not be described in detail here.

[0025] Example 2 The ore thickness detection device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the adjustment mechanism 3 includes a second mounting bracket 31, which is fixedly mounted on the upper side of the conveyor body 1. The horizontal plate of the second mounting bracket 31 has a guide groove 32 extending out of the lower surface. A bidirectional threaded rod 33 is rotatably connected inside the guide groove 32. Guide blocks 34 are threadedly fitted at the two opposite threads of the bidirectional threaded rod 33, and the guide blocks 34 are slidably connected inside the guide groove 32. The guide blocks 34 can be driven to slide inside the guide groove 32 by rotating the bidirectional threaded rod 33.

[0026] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a motor 35 is fixedly connected to the outside of the second mounting bracket 31. The output shaft of the motor 35 rotates through the interior of the second mounting bracket 31 and is fixedly connected to one end of the bidirectional threaded rod 33 via a coupling. The motor 35 can be started by an external controller to drive the rotation of the bidirectional threaded rod 33.

[0027] Among them, the motor 35 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0028] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the guiding mechanism 4 includes two first guide plates 41, both of which are located on the lower side of the second mounting frame 31. The two first guide plates 41 are fixedly connected to two guide blocks 34 respectively. A second guide plate 42 is hinged to the outside of each of the two first guide plates 41. A rubber pad 43 is fixedly connected between the second guide plate 42 and the first guide plate 41. The rubber pad 43 can effectively prevent ore from getting stuck in the gap between the first guide plate 41 and the second guide plate 42.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a connecting mechanism 7 and a limiting mechanism 8 are provided on the upper side of the conveyor body 1; The connecting mechanism 7 includes two guide rods 71, both of which are fixedly connected to the upper surface of the conveyor body 1. Sliding plates 72 are slidably sleeved on the outside of the two guide rods 71. The two sliding plates 72 are fixedly connected to the two second guide plates 42 respectively. The connecting mechanism 7 restricts the movement trajectory of the second guide plates 42, thereby preventing ore from getting stuck in the gap between the second guide plates 42 and the conveyor body 1.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the limiting mechanism 8 includes two guide seats 81, which are also fixedly connected to the upper surface of the conveyor body 1. Guide posts 82 are slidably sleeved inside the two guide seats 81. The two guide posts 82 are fixedly connected to the two first guide plates 41 respectively. The setting of the limiting mechanism 8 further ensures the stability of the first guide plates 41 when the adjusting mechanism 3 adjusts the two first guide plates 41.

[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a fan 16 is fixedly connected to the outside of the conveyor body 1. A diversion pipe 17 is fixedly connected to the upper side of the fan 16. The other end of the diversion pipe 17 is fixedly inserted into the interior of the first mounting frame 51. Telescopic pipes 18 are fixedly connected between the two moving plates 55 and the inner wall of the first mounting frame 51. The telescopic pipes 18 and the diversion pipes 17 are fixedly connected and communicate with each other. A ventilation chamber 57 is opened inside the moving plate 55, and the inside of the lever 56 is hollow. The lever 56 and the ventilation chamber 57 are connected. A dust suction hole 58 is opened on the surface of the lever 56. By starting the fan 16 through the external controller, the dust on the surface of the ore can be drawn into the interior of the ventilation chamber 57 through the dust suction hole 58 using negative pressure. Then, it enters the interior of the diversion pipe 17 through the telescopic pipe 18. Finally, it is collected and treated centrally by the external factory dust removal system.

[0032] The ore thickness detection device provided by this utility model is used as follows: First, the conveyor body 1 is started by the external controller, and the conveyor belt inside it starts to run, driving the ore to move in a predetermined direction. At the same time, the ore detection unit 2 is in a standby state, monitoring the changes in the induced current in real time to prepare for subsequent detection.

[0033] Before the ore enters the testing area, the operation of the conveyor belt drives the first drive shaft 61 to rotate. The first drive shaft 61 transmits power to the second drive shaft 62 through the synchronous pulley 63 and the synchronous belt 64, thereby driving the reciprocating screw 53 to rotate. The rotation of the reciprocating screw 53 causes the reciprocating screw sleeve 54 to slide back and forth in the cavity 52, driving the toothed plate 13 to move. The toothed plate 13 drives the support shaft 9 and the swing plate 10 to swing through the meshing transmission gear 12. In turn, it drives the two moving plates 55 and the levers 56 on their lower surfaces to move back and forth along the width direction of the conveyor belt through the connecting plate 11 and the transverse plate 14. The levers 56 actively move the ore on the conveyor belt, forcing the stacked or locally dense ore to disperse and spread out, ensuring that the ore enters the subsequent testing area in a single layer and uniform state.

[0034] After being leveled, the ore continues to move forward. The operator can drive the bidirectional threaded rod 33 to rotate via the motor 35, causing the two guide blocks 34 to slide towards or away from each other within the guide groove 32. This drives the first guide plate 41 and the second guide plate 42 to adjust their positions synchronously, thus adapting to ore of different sizes and restricting the ore's movement trajectory. During this process, the rubber pad 43 effectively prevents the ore from getting stuck in the gap between the first guide plate 41 and the second guide plate 42. At the same time, the movement of the second guide plate 42 is guided by the sliding plate 72 and the guide rod 71 in the connecting mechanism 7, while the movement of the first guide plate 41 is restricted by the guide seat 81 and the guide post 82 in the limiting mechanism 8, ensuring the overall stability and guiding accuracy of the guide plate's operation.

[0035] Finally, the ore, after being laid out and guided, enters the detection space of ore detection unit 2 in the correct orientation and single-layer arrangement. When the ore contains metallic impurities, the induced current generated by the second coil changes. The control system calculates the length, thickness, and shape of the metal based on the intensity and duration of the induced current, combined with the conveyor belt speed, thus completing the detection process.

[0036] In addition, throughout the process, the blower 16 works continuously through the diversion pipe 17, the telescopic pipe 18, the ventilation chamber 57 and the dust suction hole 58 on the lever 56, using negative pressure to suck in and centrally process the dust on the surface of the ore, keeping the testing environment clean.
