Description

Technical Field

[0001] The invention belongs to the technical field of ore mining and transportation, and in particular relates to an ore transportation system for continuous production. Background Art

[0002] Ore conveyors are a type of mining conveying equipment. In a mine, ore is transported from inside the mining site to outside the mining site through the work of ore conveyors, and then the mined ore is loaded from outside the mining site for transfer and transportation using transfer equipment such as ships and trucks.

[0003] For example, CN203803606U is an ore material conveying line, which includes: a bracket, a horizontal conveyor, a vibrating screen, an inclined conveyor, a pressure pump, hose one, hose two, and hose three, and the horizontal conveyor is fixed on the bracket; when in use, the ore material is conveyed by the inclined conveyor and the horizontal conveyor; when transshipment and transportation are required, the transshipment ships, trucks and other transshipment equipment are often moved to the end of the inclined conveyor, and the ore material transported thereon is unloaded onto the transshipment equipment through the action of the inclined conveyor; when a transshipment equipment is full, it is necessary to control the transshipment equipment to move away and control the other transshipment equipment to move to the end of the inclined conveyor. During this process, the inclined conveyor needs to be controlled to stop to prevent the ore material transported on the inclined conveyor from falling to the ground when the transshipment equipment is not placed at the end of the inclined conveyor. Summary of the Invention

[0004] The object of the present invention is to provide an ore conveying system for continuous production, by continuously arranging a first conveying line (1), a second conveying line (2) and a third conveying line, and by controlling the conveying speed of the second conveying line (2) and the third conveying line, as well as the conveying direction of the third conveying line during use, the second conveying line (2) and the third conveying line are used to temporarily store the ore material mined and conveyed through the first conveying line during the switching process of the receiving mechanism, thereby avoiding the problem of the ore material being directly discharged from the discharge end of the third conveying line during the switching process of the receiving mechanism, thereby solving the problems raised by the existing background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 any creative efforts shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] See also Figure 1 As shown, the present invention is an ore conveying system for continuous production, which can ensure that ore mining can be continuously produced when in use, and avoid frequent control of ore mining equipment to start and shut down operations during the ore mining process.

[0037] Specifically, the ore conveying system provided by the present invention includes a first conveying line 1, a second conveying line 2 and a third conveying line 3 that are continuously arranged. During actual arrangement, the end of the first conveying line 1 is controlled to be located directly above the feeding end of the second conveying line 2, and the discharging end of the third conveying line 3 is controlled to be located directly above the middle of the third conveying line 3.

[0038] At the same time, when in use, the receiving mechanism 4 including trucks and ships is controlled to be located at the discharge end of the third conveyor line 3 to receive the ore transported from the third conveyor line 3; in order to facilitate the control of the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 to perform corresponding actions when in use, the image acquisition module A21, the image acquisition module B22 and the image acquisition module C23 are respectively set at the feeding end of the first conveyor line 1, the discharge end of the second conveyor line 2 and the discharge end of the third conveyor line 3, and the first conveyor line 1, the second conveyor line 2, the third conveyor line 3, the image acquisition module A21, the image acquisition module B22 and the image acquisition module C23 are all connected to a control device.

[0039] Based on the above, when the ore conveying system provided by the present invention is used, the system operation includes the following steps:

[0040] Step 1: The image acquisition module C23 acquires image information of the material receiving mechanism 4, and the control device analyzes and determines the storage capacity M1 of the material receiving mechanism 4;

[0041] Step 2: Start the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 in sequence, and the conveying speeds of the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 are all V at this time;

[0042] Step 3: When the image acquisition module B2b acquires images and the control device analyzes and determines that the amount of ore discharged from the third conveyor line 3 reaches M2, the conveying speed of the third conveyor line 3 is controlled to slowly decrease;

[0043] Step 4: When it is detected that the amount of ore discharged from the third conveyor line 3 reaches M1, the third conveyor line 3 is controlled to switch the conveying direction and the conveying speed is controlled to V1, and the conveying speed of the second conveyor line 2 is synchronously controlled to drop to V1;

[0044] Step 5. When the image acquisition module C23 and the control device cooperate to detect and analyze that there is an empty material receiving mechanism 4 directly below the discharge end of the third conveyor line 3, the third conveyor line 3 is controlled to switch to the initial conveying direction, and the conveying speed of the third conveyor line 3 and the second conveyor line 2 is controlled to be restored to V; then return to step 3.

[0045] It can be known that, in this technical solution, the length of the third conveyor line 3 is L, and the distance between the feeding end of the third conveyor line 3 and the discharging end of the second conveyor line 2 is 0.5L;

[0046] Based on the position setting of the third conveyor line 3 and the second conveyor line 2 being closed, in the above step 4, when it is detected that the moving distance of the third conveyor line 3 after switching the conveying direction is greater than 0.45L, the third conveyor line 3 is controlled to switch the conveying direction again and maintain the conveying speed of V1 to move a distance of 0.45L, and then the third conveyor line 3 is controlled to switch the conveying direction to move a distance of 0.45L, until the image acquisition module C23 and the control device cooperate to detect and analyze that there is an empty material receiving mechanism 4 directly below the discharge end of the third conveyor line 3, the third conveyor line 3 is controlled to switch to the initial conveying direction, and the conveying speeds of the third conveyor line 3 and the second conveyor line 2 are controlled to be restored to V.

[0047] At the same time, in some exceptional cases, in step 4, when it is detected that the amount of ore discharged from the third conveyor line 3 reaches M1, the image acquisition module B22 and the control device analyze that the unloading amount from the second conveyor line 2 to the third conveyor line 3 reaches M3, and then the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 are closed. In this design, M3 is the maximum storage capacity when one side of the third conveyor line 3 is in use. That is, based on this design, when in use, it is avoided that there is excessive storage of ore material on the third conveyor line 3, which causes overload damage to the third conveyor line 3 or avoids causing too much ore material to fall from the third conveyor line 3.

[0048] When in use, the mass of M3 is smaller than that of M1, which ensures that the material stored on the third conveyor line 3 cannot fill the entire material receiving mechanism 4 when in use; and further ensures that when loading the new empty material receiving mechanism 4, it is necessary to control the transportation of the materials transported on the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 to the interior of the material receiving mechanism 4 for transfer.

[0049] At the same time, in the present invention, based on the width of the conveyor belt of the first conveyor line 1, the speed V is determined by analyzing the image acquisition module A21 and the control device, thereby ensuring that the thickness of the ore material conveyed on the conveyor belt of the first conveyor line 1 is appropriate during use to avoid falling.

[0050] It can be known that, in a specific embodiment, in order to facilitate the transportation of ore materials, increase the loading capacity of the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3, and prevent the ore materials from falling from the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 during the transportation process; Figure 2-3As shown, the first conveyor line 1, the second conveyor line 2 and the third conveyor line 3 provided by the present invention have the same structure; they all include a frame 10, and a driving roller and a driven roller are respectively provided at both ends of the frame 10, and a conveyor belt 11 is provided between the driving roller and the driven roller, and a supporting roller for supporting the conveyor belt 11 is provided on the frame 10 between the driving roller and the driven roller; the driving roller drives the conveyor belt 11 to rotate under the drive of the motor, and side baffles 13 are fixedly installed on the frames 10 on both sides of the conveyor belt 11 through support frames 12, and the side baffles 13 are used to block the ore material conveyed on the conveyor belt 11 to prevent the ore material from falling from both sides of the conveyor belt 11.

[0051] It can be known that in the above, due to the actual conveying operation, the two sides of the conveyor belt 11 will be in an up and down fluctuating state, that is, when in use, it is necessary to control the side baffles 13 when they are installed to ensure that a certain gap is formed between their bottom end faces and the two sides of the conveyor belt 11; then the ore materials conveyed on the conveyor belt 11 include not only large block materials larger than the size of an egg, but also small blocks and small particles with a particle size of less than 1 cm. In order to prevent small blocks and small particles from splashing out from the gaps on both sides of the conveyor belt 11 and falling, the present invention installs a rubber baffle 131 at the bottom end of the inner wall of the side baffle 13 by fastening bolts, and one side of the baffle 131 is against the upper surface of the conveyor belt 11; and then the baffle 131 is used to block the gap formed between the side baffle 13 and the conveyor belt 11, thereby preventing small blocks and small particles from overflowing outward from the gap formed between the side baffle 13 and the conveyor belt 11.

[0052] At the same time, when in use, some ore materials may be stuck in the gap formed between the side baffle 13 and the conveyor belt 11, as well as in the area formed by the baffle skin 131, the side baffle 13 and the conveyor belt 11; a number of flip baffles 15 are connected to the outer wall of the side baffle 13 along its length through a U-shaped connecting plate 14, one end of the U-shaped connecting plate 14 is fixedly connected to the outer wall of the flip baffle 15, and the other end is hinged to the outer wall of the side baffle 13 through a hinge 140; a protruding column 131 is also provided on the outer wall of the side baffle 13; Figure 4, a socket 132 is provided in the boss 131, and a T-shaped limit rod 134 that moves along the inner wall of the socket 132 is connected to the bottom side of the socket 132 through a spring A133; a rectangular opening 141 for the T-shaped limit rod 134 to pass through is provided on the U-shaped connecting plate 14; and a concave hole 135 is provided on the bottom side of the socket 132 of a boss 131 connected to any flip baffle 15, and the bottom side of the concave hole 135 is connected to a mounting plate 137 equipped with a pressure sensor 1371 through a spring B136; the T-shaped limit The end of the rod 134 is connected to a support plate 138 on one side of which is against the pressure sensor 1371 through a spring C1341. Based on the above, when material jamming occurs in the above-mentioned gap or area, the flip baffle 15 will be driven to flip outward. The flipping of the flip baffle 15 drives the T-shaped limit rod 134 to move outward along the socket 132, and then the pressure value detected by the pressure sensor 1371 decreases at this time; that is, when in use, when the pressure value detected by the pressure sensor 1371 decreases, it indicates that there is a material jam phenomenon.

[0053] It is known that if Figure 1 and 5 -6, when the ore material is discharged into the receiving mechanism 4 through the third conveyor line 3, the ore falling into the receiving mechanism 4 will impact the receiving mechanism 4, which may easily cause damage to the receiving mechanism 4. Based on this, a buffering blanking mechanism 5 is set at the discharge end of the third conveyor line 3. The buffering blanking mechanism 5 includes a feed hopper 50 with an opening size gradually decreasing from top to bottom. The bottom end of the feed hopper 50 is connected to a rectangular tubular blanking cylinder 51, and a buffer structure A52 is set inside the blanking cylinder 51; the buffer structure The structure 52 includes a shaft 520 fixed between two opposite inner walls of the blanking cylinder 51, and a buffer baffle 521 is connected to the shaft 520. The two ends of the shaft 520 protrude from the through holes set on the side walls of the blanking cylinder 51; and the two opposite outer walls of the blanking cylinder 51 are respectively provided with a U-shaped mounting frame 511, and the U-shaped mounting frame 511 is installed with a bearing 512. The two ends of the shaft 520 are respectively mounted on the bearing 512, so that the ore material impacts the buffer baffle 521 when falling to slow down.

[0054] Specifically, in order to improve the buffering effect, such as Figure 5-7A buffer structure B53 is further provided in the blanking cylinder body 51 located below the buffer structure A52. The buffer structure B53 includes a rectangular frame 531. The outer side wall of the rectangular frame 531 is provided with two protruding columns 532. The protruding columns 532 are provided with through holes 533. A rectangular rod 534 is inserted into the two through holes 533 located on the same side of the blanking cylinder body 51. A locking bolt A535 is provided on the top of the protruding column 532. The outer side wall of the blanking cylinder body 51 is provided with a protrusion 510 located between the two protruding columns 532. A locking bolt B536 with an end portion resting on the protruding column 510 is threadedly connected to the rectangular rod 534. A plurality of buffer modules are assembled on the rectangular frame 531. The buffer module includes a buffer rod 54. The two ends of the buffer rod 54 are respectively connected to two vertical rods 54 1. The end of the vertical rod 541 is connected to the horizontal rod 542 that rests on one side of the rectangular frame 531, and the vertical rod 541 and the horizontal rod 542 are formed in one piece; it also includes an L-shaped fixing block 55, and the L-shaped fixing block 55 is provided with a through hole for the horizontal rod 542 to pass through. The bottom end of the L-shaped fixing block 55 is provided with a locking bolt C551, and the protrusion of the L-shaped fixing block 55 rests on the upper surface of the rectangular frame 531; and the protrusion is connected to a locking bolt D552 whose end rests on the upper surface of the rectangular frame 531. At the same time, based on the settings of the rectangular frame 531 and the buffer module, it is not only convenient to install and disassemble the buffer structure B53 during use, but also convenient to adjust the distance between the buffer rods 54 according to needs during use, thereby avoiding the ore material from being stuck between two adjacent buffer rods 54.
