Specific methods of implementation

To make the purpose, technical solution and advantages of the present utility model more clear, the technical solution of the present utility model will be clearly and fully described below along with specific embodiments of the present utility model and related drawings. Apparently, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.

As shown in FIG. 1, the mineral sorting machine 100 disclosed in the present utility model contains:

feeding mechanism 11, which serves to supply ore;

the conveyor mechanism 12 is used to transport the loaded ore from the feeding mechanism 11 to a predetermined position;

the detection mechanism 13 is used to detect ore at a predetermined location;

the sorting mechanism 14 is used to sort and select the ore according to the detection results using the detection mechanism 13.

In this case, the conveyor mechanism 12 is equipped with a shock-absorbing device for buffering the impacts of ore in the conveyor mechanism 12.

The lifting mechanism 15 is used to lift the graded ores in the graded ores from underground to the surface.

The mineral sorting machine 100 can take various forms and can be represented as a metallic mineral sorting machine 100 and a non-metallic mineral sorting machine 100 in specific scenarios. Sorting machine for 100 metal minerals such as iron ore, copper ore, antimony ore and various rare earth ores. Sorting machine for 100 non-metallic minerals, such as diamond mines, coal mines, etc. The function of the mineral sorting machine 100 is to separate minerals rich in elements to be extracted from slag poor in elements to be extracted. Mineral Sorting Machine 100 screens out minerals rich in elements to be extracted for further processing to form materials beneficial to humans.

Feeding mechanism 11 serves to supply ore. The ore supplied by the feed mechanism 11 may be virgin raw material or pre-processed raw material. Primary raw materials can be obtained directly from mines by crushing or cutting. Coarse feedstocks can be obtained from virgin feedstocks by simple particle size screening, for example by eliminating ores with too large and too small diameters to obtain ores with particle sizes within a certain range. In particular, the feed mechanism 11 may be equipped with mechanisms such as restriction grooves, funnel grooves, vibrating screens and classifying screens to obtain the expected ore material. It can be understood that the specific shape of the feeding mechanism 11 here is obviously not a limitation on the specific scope of protection of the present utility model.

The conveyor mechanism 12 is used to transport ore to a predetermined location after loading the ore from the feed mechanism 11. It is understood that the conveyor mechanism 12 has a position for loading the ore. The position of the ore device can be understood as the initial position of the ore on the conveyor mechanism 12. The setting of the ore loading position is associated with the specific shape of the conveyor mechanism 12 and the feeding mechanism 11. In the practical embodiment provided for by the present utility model, the feeding mechanism 11 may be a funnel-shaped chute, a conveyor the mechanism 12 may be a conveyor belt, and the ore loading position may be a position directly below the funnel-shaped chute and opposite the conveyor belt. The predetermined position can be understood as a desired path point or desired path position of the ore in the conveyor mechanism 12. In the design idea of the mineral sorting machine 100, the predetermined position is used to distinguish between minerals or ores rich in elements to be extracted and slag or ores. , poor in elements, subject to extraction for subsequent processing. The distance or length between the ore loading location and the predetermined position is a condition that limits the miniaturization of the conveyor mechanism 12 or the mineral sorting machine 100. When the moving state of the ore at the predetermined position is relatively simple, it is advantageous for the mineral sorting machine 100 to detect the ore.

In the embodiment provided by the present utility model, the conveyor mechanism 12 is provided with a shock-absorbing device 121 to buffer the impacts of the ore in the conveyor mechanism 12. Thus, the ore moves only in the direction of the transmission, or in other words, when the ore remains stationary relative to the conveyor mechanism 12 at a given position, and there is no movement in the direction of gravity with respect to the conveyor mechanism 12, when the moving state of the ore at a given position is relatively simple, it is advantageous for the mineral sorting machine 100 to determine the ore.

Further, in the preferred embodiment provided by the present utility model, the conveyor mechanism 12 has a position for loading ore;

the shock-absorbing device 121 contains rollers and is located next to the place where ore is loaded by the conveyor mechanism 12.

It will be understood that the conveyor mechanism 12 may typically include a drive roller that moves actively, a passive roller that moves passively, and a drive belt tensioned between the drive roller and the passive roller. In the embodiment shown in the present utility model, the shock absorbing device 121 includes rollers located adjacent to the ore loading position of the conveyor mechanism 12. The ore loading position of the conveyor mechanism 12 is between the drive roller and the roller. Alternatively, the ore loading position of the conveyor mechanism 12 is located between the driven roller and the roller. Thus, the ore is supported by rollers along with driven or passive rollers and a conveyor belt. The impact force of the ore falling onto the conveyor belt is resolved by the mechanism formed by the roller, the driven roller and the conveyor belt, or the impact force of the ore falling onto the conveyor belt is resolved by the mechanism formed by the roller, the driven roller and the conveyor belt. In this way, the beating of the ore in the conveyor mechanism 12 can be absorbed.

Moreover, in a preferred embodiment provided by the present utility model, the conveyor mechanism 12 includes a drive belt, the drive belt including a side facing the ore;

the rollers are located on the opposite side of the conveyor belt facing the ore side, and the distance between the rollers and the ore loading position of the conveyor mechanism 12 in the ore transporting direction is from 1 to 5 ore diameters.

It is understood that the closer the distance between the installation position of the roller and the ore loading position of the conveyor mechanism 12, the smaller the deformation of the conveyor belt, the more obvious the friction heating phenomenon, the easier it is to significantly shorten the service life of the belt. The closer the distance between the installation position of the roller and the ore loading position of the conveyor mechanism 12, the smaller the deformation of the conveyor belt, the less obvious the shock-absorbing effect, and the ore can directly impact the rollers, which will affect the service life of the rollers. Through extensive testing, it has been determined that the distance between the roller and the ore loading position in the conveyor mechanism 12 in the ore transport direction is preferably 1 to 5 times the diameter of the ore. The ore diameter here is the maximum value of the ore particle size range.

Moreover, in the preferred embodiment presented in the present utility model, the shock absorbing device 121 includes a shock absorbing cushion.

It can be understood that with this implementation method, the impact of the ore in the conveyor mechanism 12 mainly depends on the shock absorbing cushion. Compared with the above-mentioned use of the deformation of the conveyor belt to absorb the impact of the ore in the transmission mechanism 12, the service life of the drive belt can be significantly increased.

Moreover, in the preferred embodiment provided by the present utility model, the conveyor mechanism 12 includes a drive belt, the transmission belt including a side facing the ore;

the cushion is located on the side opposite to the ore side of the conveyor belt, and the cushion extends from the ore loading position of the conveyor mechanism 12 in the ore transporting direction, and the elongated length is 1 to 5 times the diameter of the ore.

The cushion extends from the ore loading position of the conveyor mechanism 12 in the ore transporting direction, and when the extension length of the cushion exceeds a certain range, the longer the cushion is, the greater the loss of the cushion will be. When the extension length of the shock-absorbing pad is too short, the shock-absorbing pad and the conveyor belt together bear the impact force of the ore loaded on the conveyor mechanism 12, causing the contact area between the conveyor belt, the drive roller and the passive roller to increase, and the generation of friction heat is more obvious and easy , which in turn leads to a significant reduction in belt service life. After several tests, it is found that the extended length of the cushion is preferably 1 to 5 ore diameters. The ore diameter here is the maximum value of the ore particle size range.

Further, in the preferred embodiment provided in the present utility model, the base of the conveyor mechanism 12 is braided, and the side facing the ore is covered with wear-resistant rubber.

The basis of the conveyor mechanism 12 is a woven fabric, which helps dissipate heat from the pores of the woven fabric. The side of the conveyor mechanism 12 facing the ore is coated with wear-resistant rubber, which can reduce the wear of ore on the transmission mechanism 12. On the one hand, it can prevent heat accumulation from aggravating and accelerating the wear of the conveyor mechanism 12, and on the other hand, use wear-resistant materials to reduce the wear of the conveyor mechanism 12 and jointly solve the problem of the short service life of the conveyor mechanism 12 on both sides.

The detection mechanism 13 is used to detect ore at a predetermined location. In another embodiment provided by the present utility model, optical means are used to separate minerals rich in elements to be recovered from slag poor in elements to be recovered. The detection mechanism 13 may use X-rays. The detection mechanism 13 may include an x-ray generation device and an x-ray detection device. The X-ray detection mechanism can determine the enrichment level of the extracted elements using optical phenomena such as X-ray transmission, diffraction and spectrum to sort the ore.

It is understood that here the detection engine 13 can load different identification or analysis models according to different types of ore to improve the efficiency and accuracy of ore sorting. For example, loading identification models for rare earth elements, loading identification models for coal mines, loading identification models for ores with different particle sizes, and loading identification models for different enrichment concentrations of elements.

See fig. 12 and fig. 13, the detection mechanism 13 disclosed in the present utility model includes:

radiation source 131;

several detectors 132 receive radiation emitted by the radiation source 131;

detector 132 is arranged as follows:

multiple detectors 132 are distributed in the same plane as the radiation source 131.

The detection mechanism 13 disclosed in the present utility model includes:

radiation source 131;

a detector 132 that receives rays emitted by the radiation source 131;

detector 132 is arranged as follows:

the normal direction of the detector crystal 132 passes through the radiation source 131.

Although the ore illustration in FIG. 12 and fig. 13 is omitted, it can be understood that the radiation source 131 is suspended above the ore, and the detector 132 receiving the rays of the radiation source 131 is located below the ore. Thus, mineral elements within the ore are detected by the detector 132 receiving rays passing through the ore.

In addition, as mentioned above, multiple detectors 132 are distributed in the same plane as the radiation source 131. In particular, by placing multiple detectors 132 and radiation sources 131 in the same plane, radiation from the same radiation source 131 can be received by multiple detectors 132, and the number of installed radiation sources 131 can be reduced. In addition, the plane in which the multiple detectors 132 and the radiation source 131 are located is perpendicular to the direction of movement of the ore. That is, when the moving direction of the ore is defined as the Y direction and the width direction of the conveyor mechanism 12 is defined as the X direction, the radiation source 131 is located above the moving ore, and a plurality of detectors 132 are located on the moving ore below, and a plurality of detectors 132 are located in the X direction. Thus, when the ore is moved to a predetermined position, it is irradiated with rays from the radiation source 131 above the ore, and a particular detector 132 of the plurality of detectors 132 below the ore receives the rays passed through the ore, thereby detecting mineral elements in the ores. Since a plurality of detectors 132 are located in the X direction, rays passing through the ores located in the X direction on the conveyor mechanism 12 are received by the respective detectors 132.

In addition, by passing the detector crystal 132 in the normal direction through the radiation source 131, it can be ensured that the detector 132 receives radiation. Here, a plurality of detectors 132 arranged in the X direction may be arranged in an arc shape such that the normal crystal direction of each detector 132 passes through the radiation source 131. That is, in the plane where the radiation source 131 and the plurality of detectors 132 are located, the plurality of detectors 132 are located in the shape of an arc, and the center of the arc overlaps with the radiation source 131.

In addition, a plurality of detectors 132 arranged in the X direction can also be arranged linearly, and by adjusting the inclination angle of each detector 132, the normal direction of the crystal of each detector 132 passes through the radiation source 131. In this case, an angle adjusting device must be provided for each detector 132 .

The radiation source 131 is used to emit detection beams, and an X-ray emitting device can generally be used in a particular implementation process. The energy supply mode of the detection wave speed emitted by the radiation source 131 may be a single energy radiation source 131 or a dual energy radiation source 131. The radiation source 131 can be installed portable or permanently. In a particular scene, an appropriate radiation source 131 is selected according to the characteristics of the ore being detected.

Moreover, the radiation source 131 is a point radiation source or a circular radiation source. It can be understood that different arrays of radiation sources 131 may send different types of energy detection beams. The test beam of rays can be either continuous spectral or characteristic spectral. Probe beams can be high energy or low energy. Which type of radiation source to select and which type of beam of energy detection beams to send can be determined according to the characteristics of the material rich in the mineral being tested. It can be understood that the detection beam beam of a ring-shaped radiation source has a larger radiation area than a point radiation source, so the energy is higher, and the resulting energy generated is higher.

The detector 132 is used to receive rays emitted by the radiation source 131 and to analyze and identify the distribution and content of certain elements in the ore to be detected according to the received radiation emitted by the radiation source 131 after penetrating the ore. Detector 132 may transmit the detection result to provide information for the next step.

The detector 132 is positioned such that the normal direction of the detector 132 passes through the radiation source 131. It can be understood that X-rays travel in a straight line, and diffraction, reflection and refraction will occur on the surface of the material. The detector 132 mainly performs imaging through the spectral transmission and scattering distribution of the ore to be detected using X-rays, and then analyzes and identifies the distribution and content of certain elements in the detected ore. Therefore, the centers of the multiple detectors 132 are located in the same plane as the radiation source 131, so that the spectral distribution of the transmitted x-ray radiation can be collected to the maximum extent, and the detection efficiency and accuracy can be improved. At the same time, since multiple detectors 132 are distributed in the same plane as the radiation source 131, it can be ensured that the beam is incident on the detector 132 in a vertical direction, thereby increasing the incident speed of the beam, thereby improving image quality.

Moreover, in the preferred embodiment provided by the present utility model, the detection mechanism 13 also includes a linear mounting groove 133 and a board 134;

multiple detectors 132 are mounted on multiple boards 134;

board 134 is inserted into mounting slot 133.

In the present utility model, the board 134 is a printed circuit board. The detector housing is formed by a detector 132, a board 134, and a housing for packaging the detector 132 and the board 134.

In the exemplary embodiment provided by the present utility model, the detection mechanism 1313 further includes a linear mounting slot 133 and a board 134, multiple detectors 132 are mounted on multiple boards 134, and detector units are built into the mounting slot 133. The detector 132 is installed on multiple boards 134. , which is convenient for accessing and transmitting relevant detection information through a preset interface. The detector package is built into the mounting groove 133, and installed on the detection mechanism 13 through the mounting groove 133, which is convenient for the circuit boards 134, and the detector 132 can be disassembled, and the type and quantity of the detector 132 can be flexibly adjusted according to the detection requirements. The higher the assembly accuracy between the detector body and the mounting slot 133, the more satisfactory the concentricity of the detector 132 relative to the radiation source 131 is. Therefore, a design in which the board 134 is built into the mounting slot 133 can improve the installation accuracy of the detector 132 due to the accuracy of the installation between the housing detector and mounting groove 133.

In addition, one side of the mounting groove 133 is made with an interference fit, and the other side is provided with an elastic clamping device 135.

In the embodiment provided by the present utility model, one side of the mounting groove 133 is installed with an interference fit, and the other side is provided with an elastic clamping device 135. The interference mechanism on one side facilitates insertion and removal of the detector package. When the detector package is installed, insert the detector package, close the elastic clamping device 135, and fix the detector package into the mounting groove 133 at the top. When the detector body is disassembled, the elastic clamping device 135 is opened to remove the detector package. On the one hand, the elastic clamping device 135 can facilitate installation of the detector body, and on the other hand, for high precision installation, only the side of the detector package that cooperates with the mounting groove 133 may be required, which reduces the cost of high precision.

Moreover, in the preferred embodiment provided by the present utility model, the linear mounting groove 133 has a curved radian shape.

It can be understood that the distribution of the linear mounting groove 133 is a curved curve, so that all detector units mounted on the linear mounting groove 133 and detector units mounted on detector bodies. The center of the detector 132 may be on the same plane as the ray source 131, so that the spectral distribution of transmitted X-rays can be collected to a greater extent, and detection efficiency and accuracy can be improved. The curved linear mounting groove 133 can ensure concentricity of the detector mounted on the board 134 when the detector assembly is inserted. Thus, with the presence of the arc-shaped mounting groove 133, an arc-shaped arrangement of a plurality of holding periods 132 can be realized.

Moreover, in the preferred embodiment presented in the present utility model, the linear mounting groove 133 receives the radiation source 131 as the center of curvature. It can be understood that the linear mounting slot 133 takes the radiation source 131 as the center of curvature, so that all the multiple boards 134 mounted on the linear mounting slot 133 and the multiple detectors 132 mounted on the multiple boards 134. Normal direction x-rays can pass through the radiation source 131, so that the spectral distribution of transmitted X-rays can be collected to a greater extent, and the detection efficiency and accuracy can be improved. The linear mounting groove 133 takes the radiation source 131 as the center of curvature, and the rays emitted by the radiation source 131 reach each detector 132 simultaneously, thereby ensuring image accuracy.

See in fig. 15, further, in the preferred embodiment provided for by this utility model,

the detection mechanism 13 also includes a board 134;

multiple detectors 132 are mounted on multiple boards 134;

there is an interface mechanism between two adjacent boards 134, and this interface mechanism satisfies the following conditions;

When multiple boards 134 are mated to each other through a mating mechanism between two adjacent boards 134, multiple boards 134 are arranged in an arc.

In the embodiment presented in the present utility model, the detection mechanism 13 further includes boards 134, and multiple sensors 132 are installed on multiple boards 134. It is convenient to access and transmit relevant detection information through a predefined interface. There is an interface mechanism between two adjacent boards 134 to facilitate the joining of each board 134. When multiple boards 134 are interfaced to each other through an interface mechanism between two adjacent boards 134, the interface mechanism satisfies the condition that the multiple boards 134 are arranged in an arc. Due to the above-mentioned design, the centers of multiple boards 134 and multiple detectors 132 mounted on multiple boards 134 can be in the same plane with the radiation source 131, thereby collecting the transmitted X to a greater extent. The spectral distribution of the beams improves detection efficiency and accuracy.

Moreover, in the preferred embodiment provided by the present utility model, the arcs of several boards 134 located along the arc line take the radiation source 131 as the center of curvature.

It can be understood that the arcs arranged in arcs with multiple boards 134 are distributed with the beam source 131 as the center of curvature, so that by the method of all multiple detectors 132 installed on multiple boards 134, the line direction can pass through the radiation source 131, so that the spectral the distribution of transmitted X-rays can be collected to a greater extent, and the detection efficiency and accuracy can be improved. The linear mounting groove 133 takes the radiation source 131 as the center of curvature, and the radiation emitted by the radiation source 131 reaches each detector 132 simultaneously, thereby ensuring image accuracy.

Moreover, in the preferred embodiment provided in the present utility model, the detector 132 can be mounted on a mounting socket;

the mounting socket and the radiation source 131 are in a predetermined spatial position so as to ensure that the normal direction of the detector 132 passes through the radiation source 131.

It should be noted that the mounting socket here can be understood to mean the aforementioned board 134. Alternatively, the mounting socket here can be understood as an intermediate connecting device between the board 134 and the detector 132.

In addition, in the preferred embodiment provided by the present utility model, the mounting socket is located on the detection mechanism 13.

Moreover, in the preferred embodiment provided by the present utility model, an adjustment device is provided between the mounting socket and the detector 132 to adjust the position of the detector in space so that the normal direction of the detector passes through the radiation source.

Here, a mounting socket can be understood as an intermediate connecting device between the board 134 and the detector 132. In addition, the intermediate connecting device has an angle adjustment function to adjust the orientation of the detector 132 or the normal direction of the detector 132.

In addition, in the preferred embodiment provided by the present utility model, the adjustment device is a sliding guide and a first stopper coinciding with the guide.

The direction of the sliding guide here can be the circumferential direction or the axial direction. When the sliding guide is adjusted along the circumferential direction, the circumferential distribution angle of the detector 132 relative to the radiation source 131 can be adjusted. When the sliding guide is adjusted in the axial direction, the coplanarity of the detector 132 relative to the radiation source 131 can be adjusted. The first stopper can limit the position of the detector 132 when it is installed in desired position.

Moreover, in the preferred embodiment provided by the present utility model, the adjustment device includes an angle adjuster and a second locking element defining the angle adjuster.

It is understood that here, the angle adjuster can directly adjust the orientation of the detector 132 or the normal direction of the detector 132 to correct an error of the detector 132.

Moreover, in a preferred embodiment provided by the present utility model, the detection mechanism also includes a mounting guide;

The normal direction of the mounting guide passes through the radiation source.

In the specific form of implementation presented in the present utility model, the mounting guide may be a linear mounting groove 133 with a curvature.

See fig. 15, furthermore, in the preferred embodiment provided by the present utility model, two adjacent boards 134 are installed through slots and projections.

It can be understood that the structure is simple and relatively cheap due to the mating of grooves and protrusions, while at the same time saving the space occupied by the mating mechanism and facilitating the assembly of multiple boards 134.

Moreover, in the preferred embodiment presented in the present utility model, the detection mechanism 13 also includes a board 134 and a board positioning element 134;

the board board 134 is mounted on the board positioning element 134;

The board positioning element 134 secures the board 134 and ensures accurate positioning of the board 134.

It is understood that the board 134 must be firmly mounted 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.

To summarize, in the embodiment provided by this application, the ore to be sorted can be detected using a detection mechanism that can use two or more energy detection beams, so that the composition and content of mineral elements contained in the ore can be more accurately determined ,and improve detection accuracy.

The sorting mechanism 14 is used to sort and select the ore according to the detection result of the detection mechanism 13. The function of the sorting mechanism 14 is to separate the identified ore rich in elements to be extracted from the slag poor in elements to be extracted. In this case, the sorting mechanism 14 includes a spraying device, and the spraying device has at least two different liquid spray modes for separating ore into at least three types.

In addition, in the preferred embodiment provided by the present utility model, the spray device further includes a power drive 141;

the spray device has an injection hole 142;

the actuator 141 closes the spray hole 142 in a circumferential direction to change the area of the spray hole 142 onto the spray liquid.

See in fig. 3 and fig. 4, furthermore, in the preferred embodiment provided by the present utility model, the power drive 141 is a rod-shaped element;

in the first position, the actuator 141 protrudes into the area covered by the injection holes 142;

in the second position, the actuator 141 exits the area covered by the injection ports 142.

In particular, for example, the injection hole 142 has a longitudinal cross-section for spraying liquid. In the injection hole 142 or on the outer surface of the injection hole 142, a rod-shaped actuator 141 is provided to lock the longitudinal section. In the first position, the actuator 141 protrudes into the area covered by the injection hole 142, and in the second position, the power actuator 141 protrudes from the area covered by the injection holes 142. Therefore, the injection hole 142 does not eject liquid, the injection hole 142 does not obstruct liquid jet, the injection hole 142 has liquid obstruction jet, three different motion modes: ore free-falling, ore exposed to liquid, and ore exposed to liquid obstruction, can divided into three types.

See in fig. 5 and fig. 6, further, in the preferred embodiment provided by the present utility model, the power drive 141 is a grid;

in the first position, the deformation of the actuator 141 partially covers the area covered by the injection holes 142;

in the second position, the actuator 141 returns without obstructing the area covered by the injection hole 142.

In particular, for example, the actuator 141 is a deformable parallelogram mesh. In the first position, the deformation of the actuator 141 partially covers the area covered by the injection ports 142. Some sides of the parallelogram overlap the injection port 142 to have a longitudinal section for spraying liquid. In the second position, when the parallelogram returns to the square, rectangle or all sides of the parallelogram, the longitudinal section of the injection hole 142 with the jet liquid does not overlap, there is no overlap with the range covered by the injection holes 142. Like this, like this, the injection hole 142 does not ejects liquid, the injection hole 142 does not obstruct the jet liquid, the injection hole 142 has the jet liquid obstruction, the ore is free to fall, the ore is exposed to the liquid, the ore is exposed to the obstructing liquid three different modes of movement can be divided into three.

the actuator 141 is moved in the direction of injection into the injection port 142 to change the speed of the pumped fluid from the injection port 142.

The injection hole 142 has an outlet longitudinal section through which liquid exits. When the actuator 141 is located in the injection hole 142, it may be located in a first hole depth position or a second hole depth position at different distances from the injection longitudinal section. When the actuator 141 is located outside the injection hole 142, it may also be located in a first position outside the hole or in a second position outside the hole at different distances from the longitudinal section of the injection. Thus, the injection hole 142 does not release the jet liquid, the injection hole 142 is the first obstacle jet liquid, the injection hole 142 is the second obstacle jet liquid, the ore falls freely, the ore is affected by the first obstacle liquid, the ore is affected by the second liquid obstacles of three kinds of different movement patterns can be divided into three types.

See in fig. 7 and fig. 8, in addition, in the preferred embodiment provided by the present utility model, the spray device further includes a power drive 141;

the spray device has an injection hole 142;

the actuator 141 can be rotated or moved to change the direction in which the injection port 142 sprays liquid.

Specifically, when the power drive 141 is rotated through the first angle and the second angle, the force of the jet liquid hitting the ore is different. For example, when fluid is injected through injection port 142 at an angle of 45 degrees upward relative to the direction of gravity, or when fluid is injected through injection port 142 at an angle of 60 degrees upward relative to the direction of gravity, the impact force of the fluid injected onto the ore is different. . Thus, the three different motion modes of ore free-falling, ore being impacted by fluid in the first injection direction and ore being impacted by fluid in the second injection direction, can be divided into three types.

Moreover, in the preferred embodiment provided by the present utility model, the spray device further includes a power drive: a power drive 141;

the sorting mechanism can at least access the first pressure and second pressure fluid;

the actuator 141 is moved to select the first pressure fluid or the second pressure fluid.

For example, actuator 141 may be used as a fluid selection switch to select a fluid associated with a first pressure or a fluid associated with a second pressure. Thus, the three different motion modes of the ore free-falling, the ore exposed to the first pressurized fluid, and the ore exposed to the second pressurized fluid can be divided into three types.

In addition, in the preferred embodiment provided by the present utility model, the spray device has an injection hole 142;

the mineral sorting machine can select a different number of injection holes 142 or an opening duration of the injection hole 142.

The mineral sorting machine can select different amounts of opening of the injection holes 142 or duration of opening of the injection holes 142. Three different motion modes: ore falling freely, ore being impacted by the fluid from the first row of injection holes 142, and ore being impacted by the fluid from the second row of injection holes 142, can be divided into three types. Alternatively, the ore falls freely, the ore exposed to the fluid of the first duration, and the ore exposed to the fluid of the second duration, can be divided into three types.

Moreover, in the preferred embodiment provided by the present utility model, the injection hole 142 has a first hole and a second hole;

the mineral sorting machine may open the first hole injection hole 142 or open the second hole injection hole 142.

Three different motion modes: ore falling freely, ore impacted by fluid from the first hole injection hole 142, and ore impacted by fluid from the second hole injection hole 142 can be divided into three types.

The injection device has at least two different liquid injection modes to separate the ore into at least three types. Therefore, the mineral sorting machine can simultaneously screen out three types of ore with different element concentrations to improve productivity.

In the practical embodiment provided in the present utility model, the sorting mechanism 14 includes an air atomizing device, a liquid atomizing device, or a manipulator.

Once the conveyor mechanism 12 has passed a predetermined position, the ore continues to move and is then torn away from the conveyor mechanism 12. The identified ore may be sorted and collected before or while the ore is separated from the conveyor mechanism 12.

For example, the spray device can be used to change the trajectory of the ore as it is separated from the conveyor mechanism 12, thereby changing the point at which the ore falls. It can be understood that the gas injection device only needs to be set to compressed gas to achieve the separation of ores that meet the conditions, and the implementation cost is low.

For example, the liquid spray device can be used to change the trajectory of the ore as it is separated from the conveyor mechanism 12 and then to change the point at which the ore falls. It is understood that the liquid spraying device must be equipped with pressurized liquid, and the implementation cost is relatively high, but it can achieve ore purification and provide convenience for subsequent ore processing.

For example, before separating the ore from the conveyor mechanism 12, a manipulator may be used to grab ore that meets the conditions. It can be understood that the implementation cost of using a manipulator to select ores that meet the conditions is relatively high, but the use of fine classification of ores will bring convenience to the subsequent processing of ores.

Moreover, in the preferred embodiment presented in the present utility model, the sorting mechanism 14 includes an air spray device or a liquid spray device;

the mineral sorting machine 100 also includes a second ore transport device for transporting the sorted ore.

For example, in the process of lifting ore from the conveyor mechanism 12, an air atomizing device may be used to change the flight path of the ore as it is separated from the conveyor mechanism 12, thereby changing the point at which the ore falls. It can be understood that the air atomization device only needs to be adjusted to compressed gas to achieve the separation of ores that meet the conditions, and the implementation cost is low.

For example, the liquid spray device can be used to change the trajectory of the ore as it is separated from the conveyor mechanism 12 and then to change the point at which the ore falls. It is understood that the liquid spraying device must be equipped with pressurized liquid, and the implementation cost is relatively high, but it can achieve ore purification and provide convenience for subsequent ore processing.

When the falling position of the sorted ore that meets the conditions and the position to be processed in the next step are spaced apart from each other, the second ore conveying device can be used to transport the sorted ore, thereby improving production efficiency.

For example, the jet device can be used to change the trajectory of the ore as it is separated from the conveyor mechanism 12, thereby changing the point of impact of the ore. It can be understood that the gas injection device only needs to be set to compressed gas to achieve the separation of ores that meet the conditions, and the implementation cost is low.

For example, the liquid spray device can be used to change the trajectory of the ore as it is separated from the conveyor mechanism 12 and then to change the point at which the ore falls. It is understood that the liquid injection device must be equipped with pressurized liquid, and the implementation cost is relatively high, but it can achieve ore purification and provide convenience for subsequent ore processing.
