Description

Technical Field

[0001] The invention relates to ore sorting equipment, in particular to an automatic uniform material distribution device. Background Art

[0002] After long-term mining, easy-to-mine and easy-to-select rich mineral resources have become increasingly scarce, and mining companies have had to turn to processing lower-grade, complex-composition ores, which not only increases mining costs but also places a greater burden on the environment. Faced with this dilemma, how to efficiently utilize limited mineral resources while reducing environmental pressure has become a core issue restricting the sustainable development of the mining industry.

[0003] At this critical juncture, the innovative application of photoelectric sorting and waste disposal technology provides a new idea for solving the above problems. By integrating a highly sensitive optical recognition system with a precise mechanical separation device, this technology can accurately discard the raw ore at the front end of ore processing, effectively remove useless impurities, directly improve the grade of the selected ore, and reduce subsequent processing energy consumption and costs. By introducing photoelectric sorting and waste disposal equipment in mining operations, it can not only significantly improve the comprehensive resource recovery rate and increase economic benefits, but also substantially alleviate the pressure of resource depletion and win a precious "second life" for the mine.

[0004] Although photoelectric sorting and waste disposal technology has brought revolutionary progress to the efficient utilization of mining resources, it still faces a series of challenges in practical applications, especially the uniformity and orderliness of the feed. Since ore raw materials are prone to accumulation and overlap during transportation, this directly affects the accurate recognition ability of optical sensors. When faced with dense and overlapping materials, it is difficult for sensors to accurately distinguish the optical properties of individual mineral particles, resulting in a significant reduction in sorting efficiency and accuracy. In addition, the execution of injection during the sorting process is also restricted. Considering that there is a necessary minimum time interval between two injection actions to ensure accuracy and effect, the accumulation of materials not only affects the choice of injection timing, but may also cause some target materials to fail to be separated in time, further reducing the overall sorting efficiency. In view of this, it is particularly urgent to develop an intelligent system that can achieve uniform dispersion of feed and queuing feeding. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic uniform distribution device which is beneficial to preventing ore accumulation and overlapping, allowing the ore to enter the sorting process in a uniform and dispersed state, and each injection during sorting can accurately act on the target ore.

[0033] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Embodiment 1

[0035] Figures 1 to 4 An embodiment of the automatic uniform material distribution device of the present invention is shown. The automatic uniform material distribution device of this embodiment comprises a conveying track 1, on which a material distribution mechanism 2 is provided. The material distribution mechanism 2 comprises a plurality of partitions 21 spaced apart along the width direction of the conveying track 1, and a material distribution channel 22 is formed between adjacent partitions 21. The material distribution mechanism 2 is connected to a material distribution driving mechanism 3 to achieve reciprocating motion along the width direction of the conveying track 1. The conveying track 1 preferably adopts a conveying belt. Of course, in other embodiments, the conveying track 1 may also adopt a conveying plate chain or the like.

[0036] In the automatic uniform distribution device of this embodiment, the ore enters the mixing channel 22 between the partitions 21 of the mixing mechanism 2 under the drive of the conveying track 1, and the mixing drive mechanism 3 drives the mixing mechanism 2 to reciprocate along the width direction of the conveying track 1. On the one hand, it can ensure that the ore enters the sorting process in a uniform and dispersed state, significantly improve the accuracy and stability of optical sensor recognition, and lay the foundation for subsequent precise sorting; on the other hand, considering the influence of the time interval limit of two blowing operations on the sorting accuracy, this can also optimize the ore flow, realize queuing feeding along the width direction of the conveying track 1, avoid delays in the subsequent blowing timing and loss of accuracy, ensure that each round of blowing can accurately act on the target ore, improve the overall sorting efficiency, and at the same time avoid the situation where some nozzles are overused while some nozzles are not used, thereby improving the overall life of the nozzles.

[0037] Furthermore, in the present embodiment, the material sparging mechanism 2 further comprises an upper cover plate 23, the upper side of each partition plate 21 is connected to the upper cover plate 23, the upper cover plate 23 is hingedly connected to a limit plate 24 at the inlet end of each material sparging channel 22, an elastic member 25 (such as a coil spring, elastic rubber, etc.) is provided between the limit plate 24 and the upper cover plate 23, and a limit member 241 (such as a limit rod, a limit block, etc.) for limiting the rotation angle is provided on the lower side of the limit plate 24. For details, please refer to the second embodiment. Figure 6The limiter 241 constrains the movement of the limiter plate 24, limiting its downward rotation range. The minimum height of the limiter plate 24 is the maximum size of the feed ore. The elastic member 25 can increase the height of the sparging channel 22 when there is too much ore in a sparging channel 22 and squeezes the limiter plate 24 up and down. While limiting the height of the incoming material, it speeds up the passing speed of the ore and realizes the normal feeding of the ore. The structure is reasonable and effective.

[0038] Furthermore, in this embodiment, the material leveling driving mechanism 3 includes a rotary driving member 31, a rotating disk 32, a connecting rod 33, a guide rail 34, and a sliding seat 35 disposed on the guide rail 34. The rotating disk 32 is connected to the rotary driving member 31. One end of the connecting rod 33 is hinged to the rotating disk 32 and the hinge is offset from the center of the rotating disk 32. The other end of the connecting rod 33 is hinged to the sliding seat 35. The upper cover plate 23 is connected to the sliding seat 35. When working, the rotary driving member 31 drives the rotating disk 32 to rotate. Since the hinge between the connecting rod 33 and the rotating disk 32 is offset from the center of the rotating disk 32, the sliding seat 35 can be driven to reciprocate along the guide rail 34 by the connecting rod 33 when the rotating disk 32 rotates. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure a smooth and stable moving process and avoid deviation. The sliding seat 35 drives the upper cover plate 23 and the partitions 21 connected thereto to reciprocate along the width direction of the conveying track 1, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. Preferably, two guide rails 34 are provided to further enhance the guiding effect.

[0039] As a preferred embodiment, the rotating driving member 31 is a speed regulating motor, and a reducer 36 is provided between the speed regulating motor and the rotating disk 32. The speed regulating motor is used as a power source, and the speed regulating motor and the reducer 36 jointly ensure the speed change requirement, and the movement speed of the partition 21 can be conveniently controlled.

[0040] In this embodiment, the conveying track 1 is also provided with a storage bin 4 upstream of the material scrambling mechanism 2. The end of the material scrambling mechanism 2 close to the storage bin 4 is provided with side collecting plates 27 extending toward the outside of the conveying track 1 on both sides, and an upper collecting plate 28 extending upward is connected between the two side collecting plates 27.

[0041] Preferably, the storage bin 4 is formed by the enclosed plate parts, with a large top feed inlet and a small bottom discharge outlet, which is convenient for controlling the discharge speed of the material and is also conducive to the subsequent material leveling. The width of the bottom discharge outlet of the storage bin 4 is the same as the effective bandwidth of the conveyor belt, and the length (the dimension along the conveying direction of the conveyor belt) is consistent with the maximum particle size of the ore after crushing, so as to avoid the material stacking and overlap during discharge as much as possible. Preferably, vibrators 41 are arranged on both sides of the storage bin 4, and more preferably, electric vibrators. After power is turned on, the vibrators 41 vibrate, driving the storage bin 4 to vibrate, thereby accelerating the material discharge speed of the storage bin 4, preventing the material from blocking the discharge outlet, and assisting in uniformly dispersing the feeding. More preferably, a vibration reduction component (such as a rubber pad, a spring, etc.) is arranged between the storage bin 4 and the conveyor belt to reduce the vibration caused by the vibrator 41 and transmit it to the conveyor belt.

[0042] The two side collecting plates 27 cooperate to form a bell mouth, which is wide in front and narrow in the back along the moving direction of the conveyor belt, ensuring that the materials can be concentrated in the bell mouth after falling from the storage bin 4 and flowing through the conveyor belt. Therefore, the front width of the bell mouth formed by the two side collecting plates 27 should be greater than the width of the conveyor belt, and the rear narrow part should be less than or equal to the width of the conveyor belt, ensuring that all materials can be concentrated and not leaked. The bottom surfaces of the two side collecting plates 27 are parallel to the inclined conveyor belt plane, and there is a small distance between the two. The distance is usually set to one tenth of the maximum particle size of the ore, so that it is not obstructed when reciprocating. The two side collecting plates 27 are fixed to the upper collecting plate 28, the upper end of the upper collecting plate 28 is far from the conveyor belt plane, and the lower end is close to the conveyor belt plane, which preliminarily limits the height of the material flow process and avoids overlapping and stacking of materials. Specifically, the two side collecting plates 27 are connected to the outermost partition plate 21, and the upper collecting plate 28 is connected to the upper cover plate 23, and can move back and forth as a whole along the width direction of the conveyor track 1.

[0043] As a preferred embodiment, the conveyor track 1 is arranged at an angle and the height gradually decreases along the conveying direction. The inclination angle of the conveyor track 1 is 5° to 25°, and the inclination angle is further preferably 10° to 15°. The surface of the conveyor track 1 is provided with a pattern for increasing friction (not shown in the figure). On the one hand, the incoming ore falls onto the conveyor belt and flows along the moving direction of the conveyor belt. At the same time, the ore can accelerate the flow due to the gravity component. On the other hand, the conveyor belt adopts a patterned belt. During the material conveying process, the friction between the material and the conveyor belt is increased, which is convenient for controlling the stability of the material and provides a basis for subsequent orderly feeding.

[0044] Embodiment 2

[0045] Figures 5 to 7 An embodiment of the automatic uniform material distribution device of the present invention is shown. The automatic uniform material distribution device of this embodiment is basically the same as that of the first embodiment, except that:

[0046] In this embodiment, the partition 21 is hinged with a swing plate 211 at the outlet end of the material mixing channel 22, and the upper sides of the swing plates 211 are connected by a connecting plate 26, and the material mixing drive mechanism 3 is connected to the connecting plate 26. That is, in this embodiment, the partition 21 no longer moves back and forth, but the material mixing drive mechanism 3 drives the swing plates 211 to swing back and forth along the width direction of the conveying track 1 through the connecting plate 26. After the ore passes through the material mixing channel 22, the swing plate 211 can also optimize the flow of the ore, so that the ore enters the subsequent sorting process in a uniform and dispersed state.

[0047] Furthermore, in the present embodiment, three connecting columns 261 are provided on the connecting plate 26 along the length direction, the material leveling driving mechanism 3 includes a rotating driving member 31, a turntable 32, a connecting rod 33, a guide rail 34 and three sliding seats 35 provided on the guide rail 34, the sliding seat 35 is provided with an arc guide groove 351, the three connecting columns 261 are respectively passed through the three arc guide grooves 351, the turntable 32 is connected to the rotating driving member 31, one end of the connecting rod 33 is hinged to the turntable 32 and the hinge point deviates from the center of the turntable 32, and the connecting column 261 located in the center is passed through the other end of the connecting rod 33. During operation, the rotating driving member 31 drives the turntable 32 to rotate. Since the hinge between the connecting rod 33 and the turntable 32 deviates from the center of the turntable 32, the connecting rod 33 can drive the connecting column 261 located in the center to move when the turntable 32 rotates. The connecting plate 26 and the connecting columns 261 on both sides move with the connecting column 261 in the center, thereby driving the swing plates 211 under the connecting plate 26 to swing back and forth along the width direction of the conveying track 1. The sliding seat 35 moves back and forth along the guide rail 34 driven by the connecting column 261. The guide rail 34 provides a guiding effect for the sliding seat 35 to ensure that the movement process is stable and smooth and avoids deviation. The arc guide groove 351 on the sliding seat 35 provides a guiding effect for the connecting column 261, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. The structure is reasonable and effective.

[0048] Participate specifically Figure 7 Furthermore, in this embodiment, rolling elements 352 (such as ball bearings) are arranged around the circular arc guide groove 351, which can reduce the friction resistance and wear between the circular arc guide groove 351 and the connecting column 261, and the structure is simple and reliable.

[0049] Embodiment 3

[0050] Figure 8 An embodiment of the automatic uniform material distribution device of the present invention is shown. The automatic uniform material distribution device of this embodiment is basically the same as the first embodiment and the second embodiment, except that:

[0051] In this embodiment, two connecting plates 26 are provided downstream of the partition 21, and multiple shifting rods 262 are provided on the connecting plates 26. Preferably, the multiple shifting rods 262 are staggered (or not colinear) along the movement direction of the conveyor belt, which is beneficial to enhance the material leveling effect. The material leveling drive mechanism 3 includes a rotating drive member 31, a bending rod 321, two connecting rods 33, two guide rails 34 and a sliding seat 35 provided on the guide rail 34. The bending rod 321 is connected to the rotating drive member 31, one end of each connecting rod 33 is hinged to the bending rod 321, and the other end of each connecting rod 33 is hinged to each sliding seat 35 in a one-to-one correspondence. Each connecting plate 26 is connected to each sliding seat 35 in a one-to-one correspondence, and the moving directions of two adjacent connecting plates 26 are opposite. During operation, the rotating driving member 31 drives the bending rod 321 to rotate. Since the connecting rod 33 is hinged to the bending rod 321, the connecting rod 33 can drive the sliding seat 35 to move back and forth along the guide rail 34 when the bending rod 321 rotates, and the movement of different connecting rods 33 can be asynchronous. The guide rail 34 provides a guiding function for the sliding seat 35 to ensure that the moving process is stable and smooth to avoid deviation. The sliding seat 35 drives the connecting plate 26 and the connected levers 262 to move back and forth along the width direction of the conveying track 1, thereby optimizing the flow of ore and allowing the ore to enter the subsequent sorting process in a uniform and dispersed state. Since the moving directions of the two adjacent connecting plates 26 are opposite, the two cooperate with each other to further enhance the material leveling effect. Of course, in other embodiments, the number of connecting plates 26 can also be adjusted (the connecting rod 33, the guide rail 34 and the sliding seat 35 can be adjusted accordingly).

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
