[0069] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0070] Please refer to Figure 1 The mineral sorting machine 100 disclosed in the present application includes:

[0071] A feeding mechanism 11, for supplying ore;

[0072] The conveying mechanism 12 is used to transport the ore to a predetermined location after the ore is loaded from the feeding mechanism 11;

[0073] A detection mechanism 13, used to detect the ore at a predetermined position;

[0074] The sorting mechanism 14 is used to sort and pick up the ore according to the test results of the testing mechanism 13;

[0075] The transmission mechanism 12 is provided with a buffer device for buffering the jumping of the ore in the transmission mechanism 12 .

[0076] The lifting mechanism 15 is used to lift the classified ores that meet the requirements from underground to the surface.

[0077] The mineral sorting machine 100 can have various forms, and in specific scenarios it can be expressed as a metal mineral sorting machine 100 and a non-metal mineral sorting machine 100. Metal mineral sorting machines 100, such as iron ore, copper ore, antimony ore, and various rare earth metal ores. Non-metal mineral sorting machines 100, such as diamond mines, coal mines, etc. The function of the mineral sorting machine 100 is to separate minerals rich in the elements to be extracted from slags poor in the elements to be extracted. The mineral sorting machine 100 screens out minerals rich in the elements to be extracted for further processing to form material materials that are beneficial to mankind.

[0078] The feeding mechanism 11 is used to supply ore. The ore supplied by the feeding mechanism 11 can be primary raw material or pre-processed rough-processed raw material. The primary raw material can be directly obtained from a mine by crushing or cutting. The rough-processed raw material can be obtained by simple particle size screening of the primary raw material, for example, excluding ores with too large or too small diameters to obtain ores with a particle size within a certain range. Specifically, the feeding mechanism 11 can be provided with limiting grooves, funnel grooves, vibrating screens, grading screens and other mechanisms to obtain ore raw materials that meet expectations. It can be understood that the specific form of the feeding mechanism 11 here obviously does not constitute a limitation on the specific protection scope of the present application.

[0079] The transmission mechanism 12 is used to transport the ore to a predetermined position after loading the ore from the feeding mechanism 11. It can be understood that the transmission mechanism 12 has a position for loading the ore. The position of the device ore can be understood as the initial position of the ore on the transmission mechanism 12. The setting of the position for loading the ore is related to the specific form of the transmission mechanism 12 and the feeding mechanism 11. In an achievable embodiment provided in the present application, the feeding mechanism 11 can be a hopper trough, the transmission mechanism 12 can be a conveyor belt, and the position for loading the ore can be a position directly opposite the conveyor belt below the hopper trough. The predetermined position can be understood as a necessary point or position of the ore on the path of the transmission mechanism 12. In the design concept of the mineral sorting machine 100, the predetermined position is used to judge the mineral or ore rich in the elements to be extracted and the slag or ore poor in the elements to be extracted for subsequent processing. The distance or length between the position for loading the ore and the predetermined position is a condition that restricts the miniaturization of the transmission mechanism 12 or the miniaturization of the mineral sorting machine 100. When the movement state of the ore at the predetermined position is relatively simple, it is convenient for the mineral sorting machine 100 to make a judgment on the ore.

[0080] In one embodiment provided in the present application, the transmission mechanism 12 is provided with a buffer device 121 for buffering the jumping of the ore in the transmission mechanism 12. In this way, the ore only moves in the transmission direction, or in other words, the ore remains stationary relative to the transmission mechanism 12 at a predetermined position, and does not move in the gravity direction relative to the transmission mechanism 12. When the movement state of the ore at the predetermined position is relatively simple, it is beneficial for the mineral sorting machine 100 to judge the ore.

[0081] Further, in a preferred embodiment provided in the present application, the transmission mechanism 12 has a position for loading ore;

[0082] The buffer device 121 includes rollers and is disposed near the position where the ore is loaded on the conveying mechanism 12 .

[0083] It is understandable that the transmission mechanism 12 can generally include a driving roller for active movement and a passive roller for driven movement, and a transmission belt arranged between the driving roller and the passive roller. In the embodiment provided in the present application, the buffer device 121 includes a roller arranged near the position of the transmission mechanism 12 for loading ore. The position of the transmission mechanism 12 for loading ore is located between the driving roller and the roller. Alternatively, the position of the transmission mechanism 12 for loading ore is located between the passive roller and the roller. In this way, the roller, the driving roller or the passive roller and the transmission belt jointly support the ore. The impact force of the ore falling into the transmission belt is resolved by the mechanism formed by the roller, the driving roller and the transmission belt, or the impact force of the ore falling into the transmission belt is resolved by the mechanism formed by the roller, the passive roller and the transmission belt. In this way, the jumping of the ore in the transmission mechanism 12 can be buffered.

[0084] Further, in a preferred embodiment provided in the present application, the transmission mechanism 12 includes a transmission belt, and the transmission belt includes a side facing the ore;

[0085] The roller is arranged on the side opposite to the side of the conveyor belt facing the ore, and the distance between the roller and the ore loading position of the conveying mechanism 12 in the ore conveying direction is 1 to 5 times the diameter of the ore.

[0086] It is understandable that the farther the distance between the roller setting position and the ore loading position of the transmission mechanism 12, the greater the deformation of the conveyor belt, resulting in a larger contact area between the conveyor belt and the roller, and the more obvious frictional heat generation phenomenon, which can easily lead to a significant shortening of the conveyor belt life. The closer the roller setting position and the ore loading position of the transmission mechanism 12, the smaller the deformation of the conveyor belt, the less obvious the buffering effect, and the roller may be directly impacted by the ore, affecting the roller life. After many tests, it was determined that the distance between the roller and the ore loading position of the transmission mechanism 12 in the ore transmission direction should be 1 to 5 times the ore diameter. The ore diameter here is the maximum value of the ore particle size range.

[0087] Furthermore, in a preferred embodiment provided in the present application, the buffer device 121 includes a buffer pad.

[0088] It can be understood that in this embodiment, the buffer pad is mainly used to buffer the vibration of the ore in the transmission mechanism 12. Compared with the above-mentioned use of the deformation of the conveyor belt to buffer the vibration of the ore in the conveyor mechanism 12, the life of the conveyor belt can be greatly improved.

[0089] Further, in a preferred embodiment provided in the present application, the transmission mechanism 12 includes a transmission belt, and the transmission belt includes a side facing the ore;

[0090] The buffer pad is arranged on the opposite side of the conveyor belt facing the ore, and the buffer pad extends from the ore loading position of the conveying mechanism 12 in the ore conveying direction, and the extending length is 1 to 5 times of the ore diameter.

[0091] The buffer pad extends from the position of the ore loading on the transmission mechanism 12 in the ore transmission direction. When the buffer pad extends beyond a certain range, the longer the length is, the more wasteful the buffer pad will be. When the buffer pad is too short, the buffer pad and the conveyor belt jointly bear the impact force of the ore loaded on the transmission mechanism 12, resulting in the larger contact area between the conveyor belt and the active roller and the passive roller, and the more obvious the frictional heat generation phenomenon is, which leads to a significant shortening of the conveyor belt life. After multiple tests, it was determined that the length of the buffer pad extension is preferably 1 to 5 times the ore diameter. The ore diameter here is the maximum value of the ore particle size range.

[0092] Furthermore, in a preferred embodiment provided in the present application, the base of the transmission mechanism 12 is a woven fabric, and the side facing the ore is coated with wear-resistant rubber.

[0093] The base of the transmission mechanism 12 is a woven fabric, which is conducive to the heat dissipation from the pores of the woven fabric. The side of the transmission mechanism 12 facing the ore is coated with wear-resistant rubber, which can alleviate the wear of the ore on the transmission mechanism 12. On the one hand, it can prevent heat accumulation from accelerating the wear of the transmission mechanism 12, and on the other hand, the use of wear-resistant materials can alleviate the wear of the transmission mechanism 12, solving the problem of the short life of the transmission mechanism 12 from two aspects.

[0094] The detection mechanism 13 is used to detect the ore at a predetermined position. In a feasible implementation mode provided in the present application, an optical means is used to separate the minerals rich in the elements to be extracted from the slag poor in the elements to be extracted. The detection mechanism 13 can use X-rays. The detection mechanism 13 can include an X-ray generator and an X-ray detector. The X-ray detector can determine the enrichment degree of the elements to be extracted through optical phenomena such as transmission, diffraction and spectrum of X-rays, thereby sorting the ore.

[0095] It is understandable that the detection mechanism 13 here can load different recognition or analysis models according to different types of ore to improve the efficiency and accuracy of ore sorting. For example, load a recognition model for rare earth elements, load a recognition model for coal mines, or load a recognition model for ores of different particle sizes, or load a recognition model for different element enrichment concentrations.

[0096] Please refer to Fig.12 and Fig.13 , the detection mechanism 13 disclosed in this application includes:

[0097] Radiation source 131;

[0098] A plurality of detectors 132 receiving radiation emitted by the radiation source 131;

[0099] The detector 132 is arranged in the following manner:

[0100] A plurality of detectors 132 and the radiation source 131 are distributed in the same plane.

[0101] The ray source 131 is used to emit detection rays, and an X-ray emitting device can usually be used in the specific implementation process. The energy supply mode of the detection wave velocity emitted by the ray source 131 can be a single-energy X-ray source 131 or a dual-energy X-ray source 131. The ray source 131 can be portable or fixed. In a specific scenario, the corresponding ray source 131 is selected according to the ore characteristics to be detected.

[0102] The detector 132 is used to receive the radiation emitted by the radiation source 131, and analyze and identify the distribution and content of specific elements in the ore to be detected based on the radiation emitted by the radiation source 131 after penetrating the ore. The detector 132 can transmit the detection results back to provide information for the next operation.

[0103] The position of the detector 132 is arranged in a manner that the normal direction of the detector 132 passes through the ray source 131. It can be understood that X-rays propagate in a straight line and will be diffracted, reflected and refracted on the surface of the material. The detector 132 mainly performs imaging through the spectral distribution after transmission and scattering of the ore to be detected by X-rays, and then analyzes and identifies the distribution and content of specific elements in the ore to be detected. Therefore, the centers of several detectors 132 and the ray source 131 are on the same plane, which can collect the spectral distribution of the transmitted X-rays to the maximum extent, thereby improving the detection efficiency and accuracy. At the same time, since several detectors 132 and the ray source 131 are distributed in the same plane, it can be ensured that the rays enter the detector 132 in a vertical direction, thereby improving the incidence rate of the rays and thus improving the imaging quality.

[0104] Further, in a preferred embodiment provided in the present application, the detection mechanism 13 further includes a linear mounting slot 133 and a board card 134;

[0105] The plurality of detectors 132 are mounted on a plurality of boards 134;

[0106] The board card 134 is embedded in the installation slot 133 .

[0107] In the present application, a feasible implementation method is provided, in which the detection mechanism 13 further includes a linear mounting slot 133 board 134, a plurality of detectors 132 are mounted on the plurality of boards 134, and the boards 134 are embedded in the mounting slot 133. The detectors 132 are mounted on the plurality of boards 134, so as to facilitate access and transmission of relevant detection information through a preset interface, the boards 134 are embedded in the mounting slot 133, and are mounted on the detection mechanism 13 through the mounting slot 133, so as to facilitate the disassembly and assembly of the boards 134 and the detectors 132, and the type and quantity of the detectors 132 can be flexibly configured according to the detection needs. The higher the assembly accuracy between the boards 134 and the mounting slot 133, the more the concentricity of the detectors 132 relative to the radiation source 131 meets the requirements. Therefore, the structure in which the boards 134 are embedded in the mounting slot 133 can improve the installation accuracy of the detectors 132 by means of the installation accuracy between the boards 134 and the mounting slot 133.

[0108] Furthermore, one side of the installation groove 133 is interference-fitted, and the other side is provided with an elastic pressing device 135 .

[0109] The present application provides an achievable implementation method, in which one side of the mounting slot 133 is interference-matched, and the other side is provided with an elastic clamping device 135. The interference-matching mechanism on one side facilitates the insertion and removal of the board 134. When installing the board 134, the board 134 is inserted, and the elastic clamping device 135 is closed to fix the board 134 on the mounting slot 133. When removing the board 134, the elastic clamping device 135 is opened to remove the board 134. On the one hand, the elastic clamping device 135 can facilitate the installation of the board 134, and on the other hand, only the side of the board 134 that matches the mounting slot 133 can be required to have a high installation accuracy, thereby reducing the cost of implementing high accuracy.

[0110] Furthermore, in a preferred embodiment provided in the present application, the linear mounting groove 133 is a curved shape with an arc.

[0111] It can be understood that the distribution of the linear mounting slots 133 is a curved curve, so that the centers of all the boards 134 installed on the linear mounting slots 133 and the detectors 132 installed on the boards 134 can be on the same plane as the radiation source 131, thereby collecting the spectral distribution of the transmitted X-rays to a greater extent and improving the detection efficiency and accuracy. The curved linear mounting slots 133 can ensure the concentricity of the detectors installed on the boards 134 when the boards 134 are inserted.

[0112] Further, in a preferred embodiment provided by the present application, the linear mounting slot 133 takes the ray source 131 as the center of curvature. It is understandable that the linear mounting slot 133 takes the ray source 131 as the center of curvature, so that all the boards 134 installed on the linear mounting slot 133 and the normal direction of the detectors 132 installed on the boards 134 can pass through the ray source 131, thereby collecting the spectral distribution of the transmitted X-rays to a greater extent, improving the detection efficiency and accuracy. The linear mounting slot 133 takes the ray source 131 as the center of curvature, and the rays emitted by the ray source 131 reach each detector 132 at the same time, thereby ensuring the imaging accuracy.

[0113] Please refer to Fig.15 , further, in a preferred embodiment provided in the present application,

[0114] The detection mechanism 13 also includes a board 134;

[0115] The plurality of detectors 132 are mounted on a plurality of boards 134;

[0116] There is a matching mechanism between two adjacent boards 134, and the matching mechanism meets the following conditions:

[0117] When the plurality of boards 134 are coupled to each other through the coupling mechanism between two adjacent boards 134 , the plurality of boards 134 are arranged in an arc.

[0118] In the embodiment provided in the present application, the detection mechanism 13 also includes a board 134, and a plurality of detectors 132 are installed on the plurality of boards 134. It is convenient to access and transmit relevant detection information through a preset interface. There is a matching mechanism between two adjacent boards 134, which is convenient for combining each board 134. When a plurality of boards 134 are matched with each other through the matching mechanism between two adjacent boards 134, the matching mechanism satisfies the condition that the plurality of boards 134 are arranged in an arc. Through the above-mentioned structural setting, the centers of the plurality of boards 134 and the plurality of detectors 132 installed on the plurality of boards 134 can be on the same plane as the ray source 131, so as to collect the spectral distribution of the transmitted X-rays to a greater extent, thereby improving the detection efficiency and accuracy.

[0119] Furthermore, in a preferred embodiment provided in the present application, the arc of the arc-shaped arrangement of the plurality of boards 134 takes the ray source 131 as the center of curvature.

[0120] It can be understood that the distribution mode of the arcs of the plurality of boards 134 arranged in an arc line with the ray source 131 as the curvature center can make the normal direction of the plurality of detectors 132 installed on the plurality of boards 134 pass through the ray source 131, thereby collecting the spectral distribution of the transmitted X-rays to a greater extent, and improving the detection efficiency and accuracy. The linear installation slot 133 takes the ray source 131 as the curvature center, and the rays emitted by the ray source 131 reach each detector 132 at the same time, thereby ensuring the imaging accuracy.

[0121] Please refer to Fig.15 Furthermore, in a preferred embodiment provided in the present application, the two adjacent boards 134 are connected via grooves and protrusions.

[0122] It can be understood that the matching of grooves and protrusions has a simple structure and is relatively cheap, while saving space occupied by the matching mechanism and facilitating assembly between multiple boards 134.

[0123] Further, in a preferred embodiment provided in the present application,

[0124] The detection mechanism 13 also includes a board card 134 and a positioning member of the board card 134;

[0125] The board 134 is installed on the board 134 positioning member;

[0126] The board card 134 positioning member fixes the board card 134 and ensures the positioning accuracy of the board card 134 .

[0127] It is understandable that the board 134 must be stably fixed on the detection mechanism 13 to ensure that the board 134 and the detector 132 are distributed in the same plane as the radiation source 131. The positioning accuracy of the board 134 directly affects the detection accuracy. Therefore, it is necessary to use the board 134 positioning piece to firmly fix the board 134 and the detector 132 at a precise position, so as to better collect the spectral distribution of the transmitted X-rays and improve the detection efficiency and accuracy.

[0128] The sorting mechanism 14 is used to sort and pick up the ore according to the detection results of the detection mechanism 1313. The function of the sorting mechanism 14 is to separate the identified minerals rich in the elements to be extracted from the slag poor in the elements to be extracted. The sorting mechanism 14 includes an injection device, which has at least two different fluid injection modes, so as to separate the ore into at least three types.

[0129] Further, in a preferred embodiment provided in the present application, the spray device further includes an actuating member 141;

[0130] The injection device has an injection hole 142;

[0131] The actuating member 141 blocks the injection hole 142 in the circumferential direction to change the area of ​​the injection hole 142 that injects the fluid.

[0132] Please refer to Figure 3 and Figure 4 , further, in a preferred embodiment provided in the present application, the actuating member 141 is a rod-shaped member;

[0133] In the first position, the actuating member 141 penetrates into the range covered by the injection hole 142;

[0134] In the second position, the actuating member 141 exits the range covered by the injection hole 142 .

[0135] Specifically, for example, the injection hole 142 has a longitudinal section for injecting fluid. A rod-shaped actuator 141 that blocks the longitudinal section is provided inside the injection hole 142 or on the outer surface of the injection hole 142. In the first position, the actuator 141 penetrates into the range covered by the injection hole 142; in the second position, the actuator 141 withdraws from the range covered by the injection hole 142. In this way, the injection hole 142 does not inject fluid, the injection hole 142 injects fluid without obstacles, and the injection hole 142 injects fluid with obstacles, and the three different movement modes of ore free fall, ore impacted by fluid, and ore impacted by obstacle fluid can be separated into three types.

[0136] Please refer to Figure 5 and Figure 6, further, in a preferred embodiment provided in the present application, the actuating member 141 is a mesh member;

[0137] In the first position, the deformation of the actuating member 141 partially overlaps with the range covered by the injection hole 142;

[0138] In the second position, the actuating member 141 returns to a state where it does not overlap with the range covered by the injection hole 142 .

[0139] Specifically, for example, the actuator 141 is a deformable parallelogram grid member. In the first position, the deformation of the actuator 141 partially overlaps with the range covered by the injection hole 142. Some sides of the parallelogram block the longitudinal section of the injection hole 142 having the injected fluid. In the second position, when the parallelogram returns to a square, a rectangle, or all sides of the parallelogram do not block the longitudinal section of the injection hole 142 having the injected fluid, there is no overlap with the range covered by the injection hole 142. In this way, the three different movement modes of the ore free fall, the ore impacted by the fluid, and the ore impacted by the obstructed fluid can be separated into three types, that is, the injection hole 142 does not inject fluid, the injection hole 142 injects fluid without obstacles, and the injection hole 142 injects fluid with obstacles.

[0140] Further, in a preferred embodiment provided in the present application, the spray device further includes an actuating member 141;

[0141] The injection device has an injection hole 142;

[0142] The actuating member 141 moves in the spraying direction of the spray hole 142 to change the speed of the fluid sprayed by the spray hole 142 .

[0143] The injection hole 142 has an injection longitudinal section from which the fluid is injected. When the actuator 141 is arranged in the injection hole 142, it can be located at a first hole depth position or a second hole depth position at a different distance from the injection longitudinal section. When the actuator 141 is located outside the injection hole 142, it can also be located at a first hole outside position or a second hole outside position at a different distance from the injection longitudinal section. In this way, the injection hole 142 does not inject fluid, the injection hole 142 first obstacle injects fluid, the injection hole 142 second obstacle injects fluid, the ore falls freely, the ore is impacted by the first obstacle fluid, and the ore is impacted by the second obstacle fluid. Three different movement modes can be separated into three.

[0144] Please refer to Figure 7 and Figure 8 , further, in a preferred embodiment provided in the present application, the injection device further includes an actuating member 141;

[0145] The injection device has an injection hole 142;

[0146] The actuating member 141 can pivot or translate to change the direction in which the fluid is sprayed from the spray hole 142 .

[0147] Specifically, when the actuator 141 pivots to the first angle and the second angle, the impact force of the jet fluid on the ore is different. For example, when the direction of the jet fluid from the jet hole 142 is 45 degrees upward relative to the gravity direction, or when the jet fluid from the jet hole 142 is 60 degrees upward relative to the gravity direction, the impact force of the jet fluid on the ore is different. In this way, the three different movement modes of the ore falling freely, the ore being impacted by the fluid in the first jet direction, and the ore being impacted by the fluid in the second jet direction can be separated into three types.

[0148] Further, in a preferred embodiment provided in the present application, the spray device further includes an actuating member 141;

[0149] The sorting mechanism can at least be connected to fluids of a first pressure and a second pressure;

[0150] The actuating member 141 moves to select the fluid with the first pressure or the fluid with the second pressure.

[0151] For example, the actuator 141 can be used as a fluid selection switch to select the fluid of the first pressure or the fluid of the second pressure. In this way, the three different movement modes of the ore falling freely, the ore being impacted by the first pressure fluid, and the ore being impacted by the second pressure fluid can be separated into three types.

[0152] Further, in a preferred embodiment provided in the present application, the injection device has an injection hole 142;

[0153] The mineral sorting machine can select different numbers of injection holes 142 to be opened or different injection holes 142 opening durations.

[0154] The mineral sorting machine can select different numbers of opening of the injection holes 142 or the duration of opening the injection holes 142. The three different movement modes of ore free fall, ore impacted by the fluid of the first number of injection holes 142, and ore impacted by the fluid of the second number of injection holes 142 can be separated into three types. Alternatively, ore free fall, ore impacted by the fluid of the first duration, and ore impacted by the fluid of the second duration can be separated into three types.

[0155] Further, in a preferred embodiment provided in the present application, the injection hole 142 has a first aperture and a second aperture;

[0156] The mineral sorting machine can choose to open the injection holes 142 of the first aperture or choose to open the injection holes 142 of the second aperture.

[0157] The mineral sorting machine can choose to open the first aperture injection hole 142 or the second aperture injection hole 142. The three different movement modes of ore free fall, ore impacted by the fluid of the first aperture injection hole 142, and ore impacted by the fluid of the second aperture injection hole 142 can be separated into three types.

[0158] The injection device has at least two different fluid injection modes so as to separate the ore into at least three types. In this way, the mineral sorting machine can screen out three ores with different concentrations of the elements to be extracted at one time, thereby improving productivity.

[0159] In a feasible implementation mode provided in the present application, the sorting mechanism 14 includes an air jet device, a liquid jet device or a robot.

[0160] After the conveying mechanism 12 passes the predetermined position, the ore continues to move and then separates from the conveying mechanism 12. Before or during the separation of the ore from the conveying mechanism 12, the identified ore can be sorted and picked up.

[0161] For example, the jet device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It can be understood that the jet device only needs to be equipped with compressed gas to achieve the separation of the ore that meets the conditions, and the cost is low.

[0162] For example, the liquid spraying device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It is understandable that the liquid spraying device needs to be configured with pressurized liquid, which has a high cost, but it can achieve the cleaning of the ore and bring convenience to the subsequent processing of the ore.

[0163] For example, a manipulator can be used to pick up the ore that meets the conditions before the ore is separated from the transmission mechanism 12. It can be understood that the cost of using a manipulator to pick up the ore that meets the conditions is high, but the refined classification of the ore brings convenience to the subsequent processing of the ore.

[0164] Further, in a preferred embodiment provided in the present application, the sorting mechanism 14 includes an air jet device or a liquid jet device;

[0165] The mineral sorting machine 100 further includes a second ore conveying device for conveying the sorted ore.

[0166] For example, the jet device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It can be understood that the jet device only needs to be equipped with compressed gas to achieve the separation of the ore that meets the conditions, and the cost is low.

[0167] For example, the liquid spraying device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It is understandable that the liquid spraying device needs to be configured with pressurized liquid, which has a high cost, but it can achieve the cleaning of the ore and bring convenience to the subsequent processing of the ore.

[0168] When the falling position of the sorted ore that meets the conditions is spatially isolated from the position to be processed in the next step, a second ore conveyor can be used to convey the sorted ore, thereby improving production efficiency.

[0169] Further, in a preferred embodiment provided in the present application, the sorting mechanism 14 includes an air jet device or a liquid jet device;

[0170] The mineral separator 100 further includes a backfill device for conveying slag.

[0171] For example, the jet device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It can be understood that the jet device only needs to be equipped with compressed gas to achieve the separation of the ore that meets the conditions, and the cost is low.

[0172] For example, the liquid spraying device can be used to change the flight trajectory of the ore when it is separated from the conveying mechanism 12, thereby changing the falling point of the ore. It is understandable that the liquid spraying device needs to be configured with pressurized liquid, which has a high cost, but it can achieve the cleaning of the ore and bring convenience to the subsequent processing of the ore.

[0173] It is understandable that after the ore raw materials are taken out from the mine, it is easy to cause the mine to collapse. For safety considerations, in this embodiment, the mineral sorting machine 100 is also provided with a backfilling device to convey slag to the ore raw material mining point.

[0174] In the embodiment provided in the present application, the transmission mechanism 12 is used to transport the ore to a predetermined position after loading the ore from the feeding mechanism 11; the detection mechanism 1313 is used to detect the ore at the predetermined position; the transmission mechanism 12 is provided with a buffer device 121, which is used to buffer the jumping of the ore in the transmission mechanism 12. In this way, the buffer device 121 can buffer the jumping of the ore in the transmission mechanism 12 as much as possible, so that the length of the transmission mechanism 12 in the transmission direction can be made as small as possible, so that the miniaturization of the mineral sorting machine 100 is easily achieved.

[0175] The lifting mechanism 15 is used to lift the classified ores that meet the requirements from underground to the surface.

[0176] Please refer to Fig. 9 , further, in a preferred embodiment provided in the present application, the lifting mechanism 15 includes a circulating conveyor belt;

[0177] The circulating conveyor belt is integrally provided with a hopper 151 for storing ore.

[0178] The circulating conveyor belt, which is integrally provided with a hopper 151 for storing ore, is mainly used to lift qualified ore from underground to the ground. Of course, the circulating conveyor belt can be driven by a motor. The side of the circulating conveyor belt close to the sorting mechanism is arranged underground, and the side away from the sorting mechanism is arranged on the ground. The circulating conveyor belt can also be provided with a plurality of steering rollers to change the specific direction of travel of the circulating conveyor belt. For example, in the specific implementation process, the hopper 151 integrally provided with the circulating conveyor belt can first move horizontally and then be lifted vertically. The hopper 151 integrally provided with the circulating conveyor belt can also be first tilted and lifted, and then lifted vertically. The circulating conveyor belt can be flexibly arranged according to the needs of the production site.

[0179] Further, in a preferred embodiment provided in the present application, the lifting device comprises a circulating conveyor belt;

[0180] A hopper 151 for storing ore can be hung on the endless conveyor belt.

[0181] Different from the above scheme, the hopper 151 for storing ore here can be hung on the circulating conveyor belt. In other words, the hopper 151 here is separable from the circulating conveyor belt, so that the hopper 151 is taken off from the circulating conveyor belt and the ore stored in the hopper 151 is dumped.

[0182] Please refer to Fig.10 , further, in a preferred embodiment provided in the present application, the lifting mechanism 15 includes a guide rail 152;

[0183] A hopper car 153 moves on the guide rails 152 .

[0184] It is understood that the circulating conveyor belt in the above scheme can work continuously or in a step-by-step cycle. The guide rail 152 here is mainly used for reciprocating work. When the hopper car 153 is full, or the ore stored in the hopper car 153 reaches a preset capacity, the hopper car 153 lifts the ore to the ground under the guidance of the guide rail 152.

[0185] Further, in a preferred embodiment provided in the present application, the guide rail 152 includes a first guide rail 152 for guiding the hopper car 153 along a first direction and a second guide rail 152 for guiding the hopper car 153 along a second direction. From the sorting mechanism to the ground, multiple guide rails 152 and corresponding guiding directions can be set to improve production efficiency.

[0186] Further, in a preferred embodiment provided by the present application, at least one of the first guide rail 152 and the second guide rail 152 is used to lift the hopper car 153 to the ground. In the actual production site, at least one of the first guide rail 152 and the second guide rail 152 is used to lift the hopper car 153 to the ground. The hopper car 153 can be lifted to the ground first, and then guided to a suitable position. The hopper car 153 can also be guided to a suitable position first, and then lifted vertically to the ground. Of course, it can be guided horizontally, inclined, or vertically, and which combination is used depends entirely on the layout of the production site.

[0187] Furthermore, in a preferred embodiment provided in the present application, the first direction or the second direction is a vertical direction.

[0188] Furthermore, in a preferred embodiment provided in the present application, the first direction is a horizontal direction; and the second direction is a vertical direction.

[0189] It is understandable that in order to make the production site structure as simple as possible, the first direction can be set to the horizontal direction and the second direction can be set to the vertical direction. The guide rail 152 extends continuously from the mined position to the position to be mined, and can be horizontally extended. The hopper car 153 can be lifted from a fixed position in the horizontal direction to the ground, which can minimize the amount of engineering caused by the change of the mining position.

[0190] Please refer to Fig.11 Furthermore, the present application also provides a mineral sorting machine 100, comprising:

[0191] A feeding mechanism 11, for supplying ore;

[0192] The conveying mechanism 12 is used to transport the ore to a predetermined location after the ore is loaded from the feeding mechanism 11;

[0193] The detection mechanism 1313 is used to detect the ore at a predetermined position;

[0194] The sorting mechanism 14 is used to sort and pick up the ore according to the test results of the testing mechanism 1313;

[0195] The sorting mechanism 14 further includes a lifting device for lifting the classified ores that meet the requirements from underground to the ground.

[0196] Here, the lifting device is a part of the sorting mechanism 14, and the ore sorting process is combined with the lifting process of the ore from underground to the ground.

[0197] This technical solution is particularly suitable for situations where the proportion of ore that meets the conditions is relatively small.

[0198] Furthermore, the present application also provides a mineral sorting machine 100, comprising:

[0199] A feeding mechanism 11, for supplying ore;

[0200] The conveying mechanism 12 is used to transport the ore to a predetermined location after the ore is loaded from the feeding mechanism 11;

[0201] The detection mechanism 1313 is used to detect the ore at a predetermined position;

[0202] The sorting mechanism 14 is used to sort and pick up the ore according to the test results of the testing mechanism 1313;

[0203] Wherein, the feeding mechanism 11 is located underground;

[0204] The transmission mechanism 12 is arranged underground at a side close to the feeding mechanism 11 , and is arranged on the ground at a side away from the feeding mechanism 11 .

[0205] Here, the transmission mechanism 12 has the functions of transporting the ore from the feeding mechanism 11 to a predetermined location and lifting the ore from underground to the surface.

[0206] In the embodiment provided in the present application, the mineral sorting machine 100 is at least partially located underground and at least partially located on the ground. In this way, all links of mineral sorting can be avoided from being located on the ground, which can reduce the working time of miners underground and improve production safety.

[0207] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of further restrictions, an element defined by the phrase "includes a ..." does not exclude the existence of other identical elements in the process, method, commodity or device including the element.

[0208] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
