Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ore sorting, in particular to a continuous solid-state microwave ore intelligent sorting device. BACKGROUND

[0002] With the exhaustion of easily selected rich ore resources worldwide, efficient utilization of low-grade and complex co-associated ores has become a key challenge for the sustainable development of the mining industry. In order to reduce costs and energy consumption and improve resource utilization, efficient pre-concentration in the early stage of ore dressing, especially in the waste rejection (removal of low-grade ores and waste rocks) link, has become the focus of industry research. Effective pre-concentration technology can separate a large amount of waste rock or low-value ore in advance before the ore enters the high-energy consumption crushing and concentration process, thereby significantly reducing the material quantity, energy consumption and cost of subsequent processing, and realizing green and low-carbon mineral resource development.

[0003] In recent years, solid-state microwave technology has shown great potential in the field of mineral processing due to its unique selective heating ability and strong penetration. As disclosed in a patent CN115999919A, different minerals have significantly different rates (temperature rise rates) and amplitudes of absorbing energy and converting it into heat in a microwave field due to their differences in dielectric properties. By inducing differential temperature rise in the interior of the ore through microwave irradiation, and then capturing this temperature field distribution using infrared thermal imaging technology, the mineral composition and grade information of the ore can be indirectly reflected. This method has strong penetration and can detect internal information of the ore, and is not sensitive to the surface state of the ore, providing a new technical approach for online, rapid and non-contact grade identification of blocky ores.

[0004] However, the successful application of solid-state microwave technology to continuous and efficient industrialized intelligent sorting still faces the following engineering challenges: different particle sizes of ores have different microwave energy absorption and heat conduction characteristics, which may lead to misjudgment of ores of the same grade due to size differences. Although the patent CN115999919A proposes a grading treatment idea, how to realize efficient and dynamic integration with the continuous sorting process still needs to be optimized. On a continuous production line, it is necessary to ensure that the ore passes through the identification area in a uniform, single-layer and non-overlapping state after microwave irradiation, so that the infrared camera can accurately capture the temperature field of each ore. At the same time, the identification algorithm needs to quickly and accurately process the thermal image and drive the sorting mechanism to act in real time, which puts high requirements on material distribution control, image processing speed and actuator response time.

[0021] Based on the above technical solutions, in order to ensure that the feed assembly can be stably assembled and operated on the conveying device, and to achieve speed matching with the conveying device and to arrange the ore to the center of the corresponding conveying channel and to arrange it evenly, the following technical solutions are provided.

[0022] The feeding assembly includes a splined shaft and two sets of adjusting mechanisms arranged symmetrically in the conveying channel.

[0025] The spline shaft and the rotating bracket are respectively fixed with a first sprocket and a second sprocket, and the first sprocket and the second sprocket are connected by a chain.

[0026] Based on the above technical solutions, in order to ensure that the microwave radiation device and the identification device can be stably assembled on the mounting frame and to realize the efficient irradiation heating and identification operation of the passing ore, the following technical solutions are provided.

[0027] An installation cover is fixedly installed on the installation frame. The microwave radiation device is fixedly installed in the installation cover and arranged vertically downward.

[0031] The beneficial effects of this invention are: 1. By integrating a raw ore grading system, the ore is graded by particle size and distributed to independent conveying channels, achieving ore grading and dedicated channel selection. This effectively overcomes the identification errors caused by differences in microwave absorption and thermal conduction between ores of different particle sizes, ensuring that ores of the same grade, regardless of size, can obtain consistent identification criteria, significantly improving the accuracy and reliability of sorting.

[0032] 2. The transmission speed of the conveying device is dynamically linked to the supply speed of the feeding device through a correlation control device. When the conveying speed changes, the feeding opening can be automatically adjusted to prevent material from accumulating or interrupting the flow at the inlet, ensuring a continuous, stable, and uniform material flow throughout the entire process. This lays a solid foundation for subsequent uniform microwave irradiation and accurate identification, greatly improving the overall processing efficiency and automation level.

[0033] 3. The conveying device is equipped with matching inter-feed and feed-forward components, which can evenly distribute the ore at set intervals, effectively avoiding ore stacking and mutual obstruction. This centrally distributed two-stage feeding system ensures that each piece of ore passes through the recognition device area with the optimal posture and spacing, creating ideal conditions for the infrared camera to obtain clear, complete, and interference-free individual thermal images, fundamentally improving the accuracy of the image recognition algorithm.

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0037] Please see Figures 1-3 A continuous solid-state microwave intelligent ore sorting device, comprising: Conveying device 1, which is used for continuous transport of ore, includes multiple conveying channels 11 arranged side by side; A feeding device is assembled at the upstream end of the conveying device 1 and is used to supply ore for sorting to each conveying channel 11. The associated control device 3 is matched with the conveying device 1 and the feeding device, and the ore supply speed of the feeding device is adjusted by the transmission speed of the conveying device 1. The material equalization device includes an intermittent material assembly 41 and a material equalization assembly 42, which are assembled on each conveying channel 11 and arranged sequentially on the downstream side of the feeding device. The intermittent material assembly 41 is used to periodically release the ore in the conveying channel 11, and the material equalization assembly 42 is used to arrange the ore at the center of the conveying channel 11 and arrange it evenly. The microwave radiation device 5 and the identification device 6 are assembled on the transmission path of the conveying device 1 and arranged in sequence. The microwave radiation device 5 is arranged on the downstream side of the material equalization device and is used to heat the ore passing through. The identification device 6 identifies the ore quality according to the heating range and speed of the ore. The sorting device 7 sorts and feeds the ore according to the identification criteria of the ore.

[0038] For the solid-state microwave ore intelligent sorting equipment provided in this solution, the feeding device divides the crushed ore according to particle size and supplies it to each conveying channel 11 of the conveying device 1, and the conveying device 1 drives the ore to be stably transported along the transmission path.

[0039] The conveying device 1 can adjust the opening of the feeding device through the associated control device 3, thereby controlling the feeding speed of the feeding device to supply ore. Specifically, when there is a lot of ore accumulated at the upstream end of the conveying channel 11, the conveying speed of the conveying device 1 is actively increased. At this time, the operating speed of the conveying device 1 can act on the associated control device 3, and then the associated control device 3 controls the opening of the feeding device to decrease, so as to reduce the feeding speed of the feeding device. Under the state of increased conveying speed and decreased feeding speed, the ore accumulated at the upstream end of the conveying device 1 can be quickly transferred to the downstream end, ultimately preventing the ore from accumulating at the upstream end of the conveying channel 11.

[0040] When the ore accumulated at the upstream end of the conveying device 1 returns to normal, the conveying speed of the conveying device 1 is actively controlled to return to normal. The opening of the feeding device is passively restored to normal through the associated control device 3, so as to ensure stable ore supply and transmission.

[0041] In summary, by adjusting the transmission speed of the conveying device 1, the continuous and stable supply and transmission of ore can be controlled to ensure the stable operation of subsequent processes.

[0042] During the continued transport of ore, the installed equalization device operates in conjunction with the intermittent material component 41, which periodically controls the on / off state of the ore transport in the transport channel. Each time, a portion of the ore is allowed to pass through and enter the main material component 42, thus preventing the main material component 42 from being overloaded when all the ore rushes to it, which would affect its stability in ore processing.

[0043] When some ore passes through the intermediate material component 41 and enters the upstream side of the main material component 42, the main material component 42 only allows single pieces of ore to pass through the center of the main material component 42 one by one. With the help of the differential speed effect between the main material component 42 and the conveying device 1, that is, the ore has a lower transmission speed when driven by the main material component 42, and the transmission speed returns to normal (higher) when driven by the conveying device 1 after passing through the main material component 42. This allows the ore to increase its speed after passing through the main material component 42 one by one and increase the distance between it and the ore that passes through later, so as to facilitate the identification device 6 and the sorting device 7 to identify and sort the ore one by one.

[0044] After the ore enters the microwave radiation device 5, it is heated and then identified by the identification device 6. Specifically, the identification device 6 uses an industrial computer application-based recognition algorithm to intelligently identify the image and transmission speed. This involves steps such as grayscale extraction of features from the captured infrared image, using deep learning algorithms to analyze the temperature information of each ore in the thermal image, and determining whether the ore is waste rock or low, medium, or high grade ore based on pre-set temperature difference ranges and other threshold criteria. Finally, the time point when the ore reaches the sorting device 7 is determined by calculating the transmission speed of the conveyor 1. The sorting device 7 then performs the corresponding selection actions to sort and discharge the identified ore.

[0045] Based on the above technical solutions, in order to ensure that the above components can be stably assembled and operate in coordination, so as to achieve accurate identification and sorting of ore, the following technical solutions are provided.

[0046] It also includes an installation frame 8, a conveying device 1, a feeding device, a related control device 3, a material equalization device, a microwave radiation device 5, an identification device 6, and a sorting device 7, all of which are mounted on the installation frame 8. The installation frame 8 is also equipped with multiple hoppers 81 arranged at the downstream end of the conveying device 1.

[0047] The mounting frame 8 ensures that all devices are stably assembled on it and operate in accordance with their set functions. The multiple hoppers 81 are used to store different types of sorted ore. When the hoppers 81 are full, they can be replaced to facilitate continuous and efficient sorting of ore. Example 2

[0048] Please see Figures 1-4 To ensure that the conveying device 1 can stably transport ores of different screening particle sizes along a specific conveying channel 11, and to adjust the parameters for microwave irradiation and intelligent identification for ores within a specific particle size range, the following technical solution is provided.

[0049] The conveying device 1 includes a conveyor roller 12, a conveyor belt 13, and a drive motor 14. The conveyor belt 13 is arranged horizontally and surrounds the periphery of multiple sets of horizontally arranged conveyor rollers 12. One set of conveyor rollers 12 is connected to the drive motor 14. Multiple sets of parallel material guide plates 82 are also fixed on the mounting frame 8. The material guide plates 82 are used to divide the conveying device 1 into various conveying channels 11. Each set of material guide plates 82 extends along the conveying path of the conveying device 1.

[0050] The drive motor 14 is fixedly installed on the mounting frame 8, while the transmission roller 12 is rotatably installed on the mounting frame 8. When the drive motor 14 is working, it can drive the transmission roller 12 to operate stably, thereby driving the transmission belt 13 and the ore carried on it to be transported stably. Finally, the ore is transported to the end of the path, sorted by the sorting device 7, and then falls into the corresponding hopper 81 for collection.

[0051] The conveying device 1 also includes a dust removal component assembled into the mounting frame 8. The dust removal component is used to capture the dust raised during transportation to ensure that the ore sorting environment is not affected by dust.

[0052] The ore is graded by particle size and distributed to independent conveying channels 11, achieving ore grading and dedicated channel selection. This effectively overcomes the identification errors caused by differences in microwave absorption and thermal conduction between ores of different particle sizes, ensuring that ores of the same grade, regardless of size, can obtain consistent identification criteria, significantly improving the accuracy and reliability of sorting.

[0053] To ensure that the conveying device 1 can effectively receive and transport the ore supplied by the feeding device according to particle size classification, and to stably transport each type of ore according to its corresponding conveying channel 11, the following technical solution is provided.

[0054] The mounting frame 8 is fixedly installed with a bearing pad 83 arranged below the upper conveyor belt 13. The feeding device includes multiple sets of hoppers 21 arranged evenly at the upstream end of the conveying device 1 and valve plates 22 slidably installed in each set of hoppers 21. Each set of hoppers 21 is connected to each conveying channel 11.

[0055] The support plate 83 provides stable support for the conveyor belt 13, ensuring that the conveyor belt 13 can effectively carry the ore and transport it stably.

[0056] The feeding device also includes a vibrating feeding mechanism. After the crushed ore is introduced into the vibrating feeding mechanism, it is screened by the screens with different apertures at the bottom of the mechanism. The ore of different particle sizes can be distributed to each hopper 21. Then, by controlling the opening and closing posture of the valve plate 22, the ore of different particle sizes can be distributed in the corresponding conveying channel 11. Example 3

[0057] Please see Figures 4-6 To ensure the stable installation and operation of the associated control device 3, and to achieve the matching connection with the conveying device 1 and the feeding device, the following technical solution is provided.

[0058] The associated control device 3 includes a mounting base 31, a counterweight slider 32, a guide shaft 33, a rotating sleeve 34, and a connecting rod 35. The mounting base 31 is rotatably mounted on the mounting frame 8 and is dynamically connected to the transmission roller 12. The mounting base 31 has multiple sets of radial grooves 311 arranged in a ring array. Each set of radial grooves 311 has a counterweight slider 32 slidably mounted in it. The radial grooves 311 are also equipped with support springs A312 that abut against the counterweight slider 32. The guide shaft 33 is slidably mounted on the mounting base 31 and runs along the axial direction of the mounting base 31. The rotating sleeve 34 is rotatably mounted on the guide shaft 33 and is hinged to each set of counterweight sliders 32 through the connecting rod 35. The guide shaft 33 is fixedly connected to the valve plate 22.

[0059] A guide rod 313 is fixedly connected to the axis inside the mounting base 31, and a guide shaft 33 is sleeved on the periphery of the guide rod 313 to ensure that the guide shaft 33 slides stably along the axial direction of the mounting base 31. A support spring B314 is also sleeved on the guide rod 313 to keep in contact with the guide shaft 33.

[0060] When the mounting base 31 is in a static natural state, the combined action of the support springs A312 and B314 enables each set of counterweight sliders 32 to be positioned close to the axis in the radial groove 311, and then the guide shaft 33 is positioned in an outward-extending posture by the action of the connecting rod 35 and the rotating sleeve 34.

[0061] When the rotating sleeve 34 on the guide shaft 33 rotates together with the mounting base 31, it can ensure that the guide shaft 33 only moves along the axial direction and avoids invalid rotation. At the same time, it can ensure that the connection can stably transmit power to the guide shaft 33, thereby driving the valve plate 22 fixed to it to achieve synchronous movement.

[0062] When the assembly base 31 rotates with the transmission roller 12 in the conveying device 1, the counterweight slider 32 therein is subjected to centrifugal force and overcomes the support springs A312 and B314 to slide outward along the radial groove 311. At the same time, through the linkage of the connecting rod 35 and the rotating sleeve 34, the guide shaft 33 can be driven to retract into the assembly base 31, thereby driving the valve plate 22 to slide into the hopper 21 to reduce the opening of the feeding device and the feeding speed.

[0063] When the operating speed of the conveying device 1 is adjusted, it can be reflected in the change of the rotation speed of the conveying roller 12, thereby adjusting the rotation speed of the mounting base 31 and the centrifugal force on the counterweight slider 32. With the help of the associated control device 3, the dynamic balance between the conveying device 1 and the feeding device can be achieved, thereby ensuring the continuous, uniform and stable transmission of ore.

[0064] To ensure that the associated control device 3 can achieve a stable connection with the conveying device 1 and the feeding device, so as to stably adjust the opening and closing posture of each group of hoppers 21, the following technical solution is provided.

[0065] One set of transmission rollers 12 has a first bevel gear 121 fixedly connected to both ends. The associated control device 3 includes two sets arranged symmetrically. Each set of mounting bases 31 has a second bevel gear 315 fixedly connected to maintain meshing with the first bevel gear 121.

[0066] Each valve plate 22 is fixedly connected to the connecting bracket 23, which is slidably mounted on the mounting frame 8. The guide shafts 33 of the two sets of associated control devices 3 are fixedly connected to the connecting bracket 23.

[0067] When the conveying device 1 is running, the first bevel gear 121 on the transmission roller 12 can drive the second bevel gear 315 and the mounting base 31 in the associated control device 3 to operate stably, thereby triggering the associated control device 3. Through the extension and retraction of the guide shaft 33 and the rotation speed of the transmission roller 12, the valve plates 22 in each group of hoppers 21 are driven to slide synchronously through the connecting bracket 23, so as to effectively adjust the ore supply speed. Example 4

[0068] Please see Figure 3 , Figures 7-10 To ensure that the material handling assembly 41 can be stably assembled and operated on the conveying device 1, and to achieve speed matching with the conveying device 1 and effective processing of ore in each group of conveying channels 11, the following technical solutions are provided.

[0069] The material handling assembly 41 includes a rotating bracket 411, a telescopic baffle 412, a support spring C413, and a guide wheel 414. The rotating bracket 411 is rotatably mounted on the material guiding baffle 82 and arranged in the conveying channel 11. The rotating bracket 411 has multiple sets of radial through grooves 4111 arranged in an annular array. The telescopic baffle 412 is slidably mounted in each set of radial through grooves 4111. The support spring C413 is assembled onto the telescopic baffle 412 and connected to the rotating bracket 411. The guide wheel 414 is rotatably mounted to both ends of the telescopic baffle 412 and arranged around the rotating bracket 411. The side walls of each set of material guiding baffles 82 are fixedly connected with limiting strips 821 that cooperate with the guide wheel 414. The rotating brackets 411 in each set of material handling assemblies 41 are all coaxially fixedly connected.

[0070] A first pulley 122 and a second pulley 4112 are fixedly connected to the transmission roller 12 and the rotating bracket 411, respectively. The first pulley 122 and the second pulley 4112 are connected by a belt.

[0071] Each set of coaxially fixed rotating brackets 411 stably receives the power of the transmission roller 12 through the combination of the first pulley 122, the second pulley 4112 and the belt strip. By adjusting the size and model of the first pulley 122 and the second pulley 4112, the operating speed of the material handling assembly 41 can be reduced when the power is transmitted to it.

[0072] This, in turn, drives the rotating bracket 411 in each set of material handling components 41 and the telescopic baffle 412 mounted on it to achieve low-speed synchronous operation.

[0073] The support spring C413 ensures that the corresponding telescopic baffle 412 always extends outward from the rotating bracket 411, thereby ensuring that the telescopic baffle 412, which moves with the rotating bracket 411, can block the forward-transmitting ore for a period of time. After the rotating bracket 411 drives the telescopic baffle 412 to deflect, the ore can be released and pass through the inter-material assembly 41, thus realizing the passage of ore in batches.

[0074] When the rotating support 411 drives one of the telescopic baffles 412 to move downwards, the guide wheel 414 on the telescopic baffle 412 can be blocked and limited by the limiting strip 821, so that the telescopic baffle 412 overcomes the resistance of the corresponding support spring C413 and retracts into the rotating support 411. This allows the telescopic baffle 412, which has reached the bottom, to pass closely against the transmission belt 13, and avoids rigid collision between the telescopic baffle 412 and the transmission belt 13, thereby achieving effective blocking and material distribution of the ore.

[0075] To ensure that the feed assembly 42 can be stably assembled and operated on the conveying device 1, and to achieve speed matching with the conveying device 1 and to arrange the ore evenly at the center of the corresponding conveying channel 11, the following technical solution is provided.

[0076] The feeding assembly 42 includes a splined shaft 421 and two sets of adjusting mechanisms 422 arranged symmetrically in the conveying channel 11. The adjusting mechanism 422 includes a fixed bracket 42201 and a transverse support 42202 and a longitudinal support 42203 slidably mounted on the fixed bracket 42201. The fixed bracket 42201 is fixedly mounted on the guide plate 82. The transverse support 42202 slides along the ore conveying direction. The sliding direction of the longitudinal support 42203 is perpendicular to the sliding direction of the transverse support 42202.

[0077] The adjusting mechanism 422 also includes a drive roller 42204, a guide roller 42205, and a transmission belt 42206 wound around the drive roller 42204 and the guide roller 42205. The drive roller 42204 is rotatably mounted on the longitudinal support 42203. The guide roller 42205 is rotatably mounted on both the transverse support 42202 and the fixed support 42201. A longitudinal spring 42207 is assembled between the longitudinal support 42203 and the fixed support 42201, and a transverse spring 42208 is assembled between the transverse support 42202 and the fixed support 42201.

[0078] A transmission bevel gear 42209 is fixedly connected to the top of the drive roller 42204. A drive bevel gear 42210 that meshes with the transmission bevel gear 42209 is rotatably mounted on the longitudinal support 42203. The spline shaft 421 is slidably inserted into the drive bevel gear 42210 in the two sets of adjusting mechanisms 422. The spline shaft 421 in each set of feeding assemblies 42 is coaxially fixed.

[0079] Spline shaft 421 and rotating bracket 411 are respectively fixedly connected to sprocket 4221 and sprocket 4113. Sprocket 4221 and sprocket 4113 are connected by a chain.

[0080] By combining the first sprocket 4221, the second sprocket 4113 and the chain, the power of the conveying device 1 can be transmitted to the main material assembly 42 through the intermediate material assembly 41, thereby realizing the speed matching operation of the main material assembly 42 and the conveying device 1, so that the main material assembly 42 drives the ore through one by one at a lower operating speed than the conveying device 1.

[0081] For the adjusting mechanism 422, the elastic force of the longitudinal spring 42207 is greater than that of the transverse spring 42208. When the adjusting mechanism 422 is in its natural state, the longitudinal spring 42207 will overcome the resistance of the transverse spring 42208 through the transmission belt 42206 and drive the longitudinal support 42203 and its drive roller 42204 to move along the spline shaft 421 towards the center of the conveying channel 11. During this process, the transverse support 42202 drives its guide roller 42205 to overcome the resistance of the transverse spring 42208 and be in a retracted state, ensuring that the transmission belt 42206 is always taut.

[0082] The spline shaft 421 ensures that the power of the conveying device 1 is always transmitted to the drive roller 42204, thereby driving the transmission belt 42206 to operate stably, so as to push the ore between the two sets of adjusting mechanisms 422 forward stably, so that the ore passes through one by one and is stably transported along the center of the conveying channel 11.

[0083] As the ore passes through the two sets of adjusting mechanisms 422, the two sets of longitudinal support brackets 42203 and their drive rollers 42204 are squeezed by the ore and move to both sides of the conveying channel 11. At the same time, the transverse support bracket 42202 drives its guide rollers 42205 to extend laterally to compensate for the shrinkage of the transmission belt 42206, so that the transmission belt 42206 always remains taut, which can ensure the effective passage of various ores of different shapes.

[0084] The 42206 drive belt is made of wear-resistant and impact-resistant material, which can effectively cope with contact, compression and impact with irregular ores, and improve its durability.

[0085] Because the drive belt 42206 operates at a low speed, it passes through the ore at a low speed when interacting with it. After the ore stops interacting with the drive belt 42206, it is driven by the transmission belt 13 for transmission. Because the transmission belt 13 operates at a high speed, it can increase the distance between itself and the ore passing through, thus avoiding ore stacking, so that the identification device 6 and the sorting device 7 can effectively identify and sort it. Example 5

[0086] Please see Figure 1 , Figure 2 , Figure 11 To ensure that the microwave radiation device 5 and the identification device 6 can be stably assembled on the mounting frame 8 and to achieve efficient irradiation heating and identification of the passing ore, the following technical solution is provided.

[0087] The mounting frame 8 is fixedly mounted with a mounting cover 84. The microwave radiation device 5 is fixedly mounted in the mounting cover 84 and arranged vertically downward. The identification device 6 is fixedly mounted on the mounting frame 8 and arranged facing each conveying channel 11.

[0088] The microwave radiation device 5 mainly includes a solid-state microwave source and a wave stirrer. The solid-state microwave source is used to radiate microwaves to induce the ore to heat up, while the wave stirrer is used to make the microwave field uniformly distributed so as to radiate the ore uniformly.

[0089] Mounting bracket A85 is also fixedly installed on the mounting frame 8 for mounting the identification device 6. The identification device 6 mainly includes an infrared camera and a speed sensor. The infrared camera is used to capture infrared images of the ore for identification processing, while the speed sensor is used to detect the transmission speed of the ore so that the rear sorting device 7 can perform sorting action at a specific time point.

[0090] To ensure that the sorting device 7 can sort and store the transmitted ore according to the identification criteria, the following technical solution is provided.

[0091] The mounting frame 8 is also fixedly connected to the downstream end of the conveying device 1. The material guide plate 82 is connected to the guide plate 86. The guide plate 86 has discharge ports 861 arranged in each conveying channel 11. Each set of discharge ports 861 is equipped with a sorting device 7.

[0092] The sorting device 7 includes a baffle plate 71, a lifting bracket 72, a connecting plate 73, and a telescopic cylinder 74. One end of the baffle plate 71 is hinged to the discharge port 861 and blocks the discharge port 861. The telescopic cylinder 74 is fixedly installed on the mounting frame 8 and arranged in the vertical direction. The lifting bracket 72 is fixedly connected to the movable end of the telescopic cylinder 74. Both ends of the connecting plate 73 are hinged to the baffle plate 71 and the lifting bracket 72, respectively.

[0093] Mounting bracket B87 is also fixedly installed on mounting frame 8, and each set of telescopic cylinders 74 is fixedly installed on mounting bracket B87.

[0094] When the identified ore enters the corresponding conveying channel 11 of the guide plate 86, the extension and retraction posture of the telescopic cylinder 74 is controlled to drive the lifting support 72 to move up and down, and then the connecting plate 73 drives the baffle plate 71 to move up or down to block the discharge port 861.

[0095] When the baffle plate 71 is raised, the ore conveyed there leaks down into the corresponding hopper 81 through the discharge port 861. When the baffle plate 71 is lowered and blocks the discharge port 861, the ore conveyed there can pass along the baffle plate 71 and finally fall into another set of hoppers 81 at the end of the guide plate 86, thereby realizing the sorting operation of the ore.
