Description

Technical Field

[0001] The present invention relates to the technical field of mineral sorting, and in particular to a mineral sorting method and a sorting system thereof. Background Art

[0002] Minerals refer to the simple substances and compounds of natural elements that are produced and developed in various geological processes and are relatively stable under certain geological and physical and chemical conditions. Minerals have a relatively fixed chemical composition, and those in solid form also have a definite internal structure; they are the basic units that make up rocks and ores. After mining, minerals need to be sorted multiple times.

[0003] Chinese invention patent 2021112185009 discloses a large-particle mineral sorting device, including a turntable with adjustable speed, an ore inlet arranged along the rotation direction of the disc sorting area, a detection and identification control device, a fixed frame on the upper part for installing a fixed spray gun, a detection device, etc., a spray gun arranged along the periphery of the disc for spraying and separating minerals and tailings, a selected material collection chute, a discharge baffle and a collection chute; the sorting device has low sorting efficiency and poor sorting effect.

[0004] Chinese invention patent 2020108534430 provides an intelligent mineral sorting device, which includes a feed mixing box, a sorting space, a pulsating lifting mechanism, a first discharging mechanism and a second discharging mechanism; it also includes springs and buffer pads that play a buffering or energy storage role; the sorting device cannot realize the adaptive adjustment sorting function and is difficult to operate.

[0005] The existing mineral sorting system sorts minerals according to their particle size. Some small particles of minerals are attached to the outside of large particles of minerals due to soil. When they are vibrated and sorted, the small particles of minerals cannot fall off smoothly from the large particles of minerals, resulting in errors in the final sorted minerals, thereby reducing the use value of the sorting equipment.

[0006] When the minerals need to be collided and crushed, since the collision position in the sorting device in the prior art is fixed, the collision efficiency of the minerals is low and the collision crushing effect is poor.

[0007] When the dust impurities in the minerals are sucked and recovered, the suction direction and size in the existing devices are fixed, so the dust impurities in the minerals are recovered in a low efficiency and poorly, and the dust suction holes are easily clogged when used for a long time, thereby reducing the subsequent dust suction and impurity removal effect. When the amount of large-particle minerals gradually decreases and the amount of small-particle minerals gradually increases, the bent screen still repeatedly vibrates up and down, which will impact and crush the small-particle minerals, thereby reducing the amount of recovered qualified minerals. In addition, the existing devices lack the uniform shaking and paving effect on qualified minerals, which causes the qualified minerals to pile up, reducing the collection amount and convenience of qualified minerals. Summary of the invention

[0008] The present invention discloses a mineral sorting system, aiming to solve the technical problems involved in the above-mentioned background technology.

[0009] In order to achieve the above-mentioned object, the present invention adopts the following technical scheme: a mineral sorting system, comprising a sorting box, a controller is provided on one side of the sorting box, shaft blocks are provided on both sides of the top of the sorting box, the facing sides of the two shaft blocks are connected to the same connecting shaft through bearings, a sieve plate is provided on the outer side of the connecting shaft, a sorting auxiliary component is provided on the upper end of the sieve plate, and connecting rods are provided on the tops of both sides of the sieve plate;

[0010] The sorting auxiliary component comprises a cover frame and a rotating rod, the outer surface of the rotating rod is evenly arrayed with multiple groups of electric push rods, and the output end of the electric push rod is provided with an electromagnetic vane;

[0012] A top dust suction assembly is arranged on the top of the sorting box, and the top dust suction assembly comprises a feeding ring frame and two hollow surrounding dust suction plates, and the top of the connecting rod is fixedly connected to the bottom of the feeding ring frame.

[0013] By providing a sorting auxiliary component, after the mineral is introduced into the sorting box, it falls onto the screen plate. During the vibration screening process, the drive motor is started, and the drive motor drives the electromagnetic rotor to rotate, thereby rotating the mineral that slides there into the cover frame. The electromagnetic rotor cooperates with each matching blocking piece to separate large particles from small particles in the mineral, avoiding the two being adsorbed together and causing poor mineral sorting effect. At the same time, in the subsequent vibration sorting process of the mineral, the mineral slides to the impact arc plate, and collides with the impact ball, further improving the separation effect of small and large particles of minerals, ensuring that the minerals passing through the screen plate are all sorted, and improving the use value of the sorting system.

[0014] At the same time, when the screen plate vibrates as mentioned above, it can also effectively drive the feed ring frame to vibrate up and down, thereby improving the screening efficiency of the mineral, and the screen plate can also drive the bent screen to vibrate up and down, thereby improving the screening effect of the mineral; and when the volume of the mineral decreases, the controller controls the extension distance of the electric push rod to decrease, and the power-on current of the electromagnetic rotor increases, then the bent screen moves left and right to shake and spread the small-volume mineral.

[0015] In a preferred embodiment, the controller electrically controls each electrical component, a motor frame is provided on one side of the sorting box, a driving motor is provided on the side of the motor frame facing the sorting box, the output shaft of the driving motor is fixedly connected to one end of a rotating rod through a coupling, and the other end of the rotating rod is connected to an inner wall of one side of the sorting box through a bearing.

[0016] In a preferred embodiment, the cover frame is fixedly connected to the inner walls on both sides of the sorting box above the electromagnetic rotor blades, and matching blocking plates are equidistantly provided on the inner side of the cover frame. The top of the magnetic plate matches the bottom of the sieve plate, and the magnetic plate matches the facing end of the electromagnetic rotor blade.

[0017] In a preferred embodiment, fixing rods are equidistantly provided on the top of the sieve plate, and connecting spring rods are equidistantly provided on the top of each fixing rod, and the other end of the multiple connecting spring rods on the same fixing rod is provided with the same impact arc plate, and the impact arc plate is movably connected to the top of the sieve plate through a hinge.

[0018] In a preferred solution, slide grooves are provided on both inner walls of the sorting box, sliders are provided on both sides of the feed ring frame, the slide grooves match the sliders, deflection rails are provided on both sides of the sorting box near the bottom end of the sieve plate, the deflection rails are internally slidably connected to limit sliders, the two limit sliders are fixedly connected to both sides of the sieve plate near the bottom end, a vibration spring rod is provided on the outer side of the limit slider, and the other end of the vibration spring rod is fixedly connected to the inner wall of the deflection rail.

[0020] By providing a secondary sorting component, after the mineral sorting is completed, small particles of minerals fall onto the curved screen below. The impact caused by the high drop causes the lifting spring rod to be compressed. During the resetting process, the curved screen is driven to perform secondary sorting on the small particles of minerals, thereby further improving the mineral sorting effect.

[0021] In a preferred embodiment, a door hole is opened on one side of the sorting box, and the inner wall of the door hole is connected to the box door through a hinge. A mounting plate is provided on one side of the sorting box, one of the hollow surrounding dust suction plates is fixedly connected to the top of the mounting plate, and the other hollow surrounding dust suction plate is fixedly connected to the top of the sorting box, and a dust collecting box is provided on the top of the sorting box.

[0022] In a preferred solution, dust suction holes are opened at equal distances on the outer sides of the two hollow surrounding dust suction plates facing the feed ring frame, connecting holes are opened on the outer sides of the two hollow surrounding dust suction plates, and the same connecting pipe is arranged inside the two connecting holes. The feed ring frame is fixedly connected to the interior of the sorting box near the feed end, and impact rods are arranged at equal distances on the inner walls on both sides of the feed ring frame.

[0023] In a preferred solution, a pump bracket is provided on one side of the sorting box, a dust pump is provided on the top of the pump bracket, the dust suction end of the dust pump is connected to the inside of the connecting pipe through a pipe, the dust delivery end of the dust pump is provided with a dust delivery pipe, and the other end of the dust delivery pipe is plugged into the inside of the dust collecting box.

[0024] By setting up a top dust suction component, the mineral falls into the feed ring frame before being introduced into the sorting box.

The dust suction pump absorbs the dust generated by the collision through the hollow dust suction holes on the dust suction plate. The dust generated by the vibration screening is also introduced into the dust collection box by the dust suction pump to avoid dust causing environmental pollution to the surrounding area.

[0025] A mineral sorting method, wherein the mineral sorting system is used to sort minerals, and the method comprises the following steps:

[0026] Step 1: Before the mineral is introduced into the separation box, the top dust collection component crushes and dusts the mineral;

[0027] Step 2: After the mineral falls onto the screen plate, the rotating rod rotates and drives the screen plate to rotate, and the mineral on the top of the screen plate falls downward on the top of the bent screen;

[0028] Step three: When the volume of the mineral continues to decrease, the controller controls the electric push rod to drive the electromagnetic vane to move closer to the end of the rotating rod, the vibration amplitude of the screen plate decreases, the current of the electromagnetic vane increases, and the magnetic plate drives the bent screen to move away from the end of the electromagnetic vane to increase the distance.

[0029] From the above, we can see that

[0030] 1. The present invention sets a sieve plate and a bent sieve, and the electromagnetic rotor cooperates with each matching barrier plate to separate large particles from small particles in the mineral, thereby avoiding the adsorption of the two together and causing poor mineral sorting effect. At the same time, in the subsequent vibration sorting process of the mineral, the mineral slides onto the impact arc plate and collides with the impact ball, further improving the separation effect of small and large particles of minerals, ensuring the technical effect of all minerals passing through the sieve plate being sorted.

[0031] 2. The present invention arranges electromagnetic rotors and electric push rods, which not only realize collision, crushing and sorting of minerals, but also realizes secondary screening with the help of screen plates and bent screens, so that the sorting efficiency is higher and the sorting accuracy is better; and during the sorting process, the collision and crushing effect and the subsequent up and down vibration sorting amplitude can be adjusted according to the volume of the mineral, so that the adaptability is stronger, the stability is higher and the sorting accuracy is higher.

[0032] 3. The present invention sets a connecting rod and a feed ring frame. When all the mineral particles are small, the bending screen is used to shake to improve the paving effect of qualified minerals, so the recovery amount is higher and the uniformity is better. At the same time, the gap between the feed ring frame and the hollow surrounding dust suction plate can be adjusted automatically, so the impact crushing effect is better, and the dust suction and impurity removal adaptability and blockage clearing performance are stronger.

DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] A mineral sorting system disclosed in the present invention is mainly used in the existing mineral sorting system. During use, when sorting according to the particle size of the minerals, some small particles of minerals are attached to the outside of large particles of minerals due to soil. When they are vibrated and sorted, the small particles of minerals cannot fall off smoothly from the large particles of minerals, resulting in errors in the final sorted minerals, which leads to major problems in this sorting step.

[0043] First embodiment

[0044] Reference Figure 1 - Figure 7 A mineral sorting system includes a sorting box 1. A controller is provided on one side of the sorting box 1. The controller electrically controls various electrical components. Shaft blocks 11 are provided on both sides of the top of the sorting box 1, and the opposite sides of the two shaft blocks 11 are connected to the same connecting shaft 12 through bearings. A sieve plate 8 is provided on the outer side of the connecting shaft 12. A sorting auxiliary component 4 is provided on the upper end of the sieve plate 8. The screening of the sieve plate 8 is assisted by the sorting auxiliary component 4, and the sieve plate 8 is used to sort the minerals when working.

[0045] The sorting auxiliary component 4 includes a cover frame 404 and a rotating rod 409. The outer surface of the rotating rod 409 is evenly arrayed with multiple groups of electric push rods 413. The output end of the electric push rod 413 is provided with an electromagnetic rotor 410. A motor frame 402 is provided on one side of the sorting box 1. A driving motor 401 is provided on the side of the motor frame 402 facing the sorting box 1. The output shaft of the driving motor 401 is fixedly connected to one end of the rotating rod 409 through a coupling, and the other end of the rotating rod 409 is connected to an inner wall of one side of the sorting box 1 through a bearing. When the driving motor 401 is started, it drives the rotating rod 409 to rotate, and the rotating rod 409 rotates to drive the electromagnetic rotor 410 to rotate through the electric push rod 413.

[0046] The cover frame 404 is fixedly connected to the inner walls of the sorting box 1 on both sides above the electromagnetic rotor 410. The inner side of the cover frame 404 is equidistantly provided with matching blocking pieces 403. The matching blocking pieces 403 and the electromagnetic rotor 410 can not only realize the rotational screening and feeding of the minerals at the top of the screen plate 8, but also can reversely scrape the inner wall of the cover frame 404 and the inner wall of the matching blocking piece 403, thereby effectively improving the cleaning effect and cleaning efficiency.

[0047] Fixed rods 407 are equidistantly provided on the top of the sieve plate 8, and connecting spring rods 408 are equidistantly provided on the top of each fixed rod 407. The other ends of the multiple connecting spring rods 408 on the same fixed rod 407 are provided with the same impact arc plate 406, and the impact arc plate 406 is connected to the top of the sieve plate 8 by a hinge. When the mineral flows and discharges on the top of the sieve plate 8, the mineral collides with the impact arc plate 406, thereby effectively improving the crushing and screening effect of the mineral and ensuring the subsequent screening effect of the mineral.

[0048] In a specific application scenario, after the mineral is introduced into the sorting box 1, it falls onto the screen plate 8. During its vibration screening process, the drive motor 401 is started, and the drive motor 401 drives the electromagnetic rotor 410 to rotate, thereby rotating the mineral that slides there into the cover frame 404. The electromagnetic rotor 410 cooperates with each matching blocking plate 403 to separate large particles from small particles in the mineral, avoiding the adsorption of the two together and resulting in poor mineral sorting effect. At the same time, in the subsequent vibration sorting process of the mineral, the mineral slides onto the impact arc plate 406, and collides with the impact ball 405, further improving the separation effect of small and large particles of minerals, ensuring that all minerals passing through the screen plate 8 are sorted, and improving the use value of the sorting system.

[0049] Deflection rails 9 are provided on both sides of the sorting box 1 near the bottom end of the sieve plate 8, and the deflection rails 9 are internally slidably connected to limit sliders 14. The two limit sliders 14 are fixedly connected to both sides of the sieve plate 8 near the bottom end. A vibration spring rod 13 is provided on the outer side of the limit slider 14, and the other end of the vibration spring rod 13 is fixedly connected to the inner wall of the deflection rail 9. By means of the elastic connection between the limit slider 14 and the vibration spring rod 13, the elastic buffering effect of the sieve plate 8 is effectively improved.

[0050] In the present invention, a discharge hole 7 is opened on one side of the sorting box 1 close to the bottom end of the sieve plate 8, and a guide plate 6 is provided on the inner wall of the discharge hole 7, a telescopic belt is provided on the top of the guide plate 6, and the other end of the telescopic belt is provided at the bottom of the sieve plate 8, so that the larger minerals on the top of the sieve plate 8 are directly discharged along the guide plate 6.

[0051] A secondary sorting component 10 is provided inside the space below the screen plate 8 of the sorting box 1, and the secondary sorting component 10 includes a bent screen 1001, which is movable on an inner wall of one side of the sorting box 1, a fixed plate 1003 is provided on the inner wall of one side of the sorting box 1, and hanging spring rods 1004 are equidistantly provided at the bottom of the fixed plate 1003, the bent screen 1001 is fixedly connected to the bottoms of multiple hanging spring rods 1004, a magnetic plate 1002 is provided on the top of the fixed plate 1003, and the bottom of the bent screen 1001 is located at the inner bottom of the discharge hole 7 and below the guide plate 6.

[0052] Specifically, after the mineral sorting is completed, small particles of minerals fall onto the bent screen 1001 below. The impact caused by the high drop causes the hanging spring rod 1004 to be compressed. During the resetting process, the bent screen 1001 is driven to perform secondary sorting of small particles of minerals, thereby further improving the mineral sorting effect. The unsatisfied small particles of minerals directly reach the inner bottom of the discharge hole 7 along the bottom of the bent screen 1001 and are discharged.

[0053] A door hole is opened on one side of the sorting box 1 , and the inner wall of the door hole is connected with a box door 5 via a hinge. The arrangement of the box door 5 facilitates the discharge of qualified minerals inside the sorting box 1 .

[0054] A top dust suction component 2 is provided near the feed end of the sorting box 1, and the top dust suction component 2 realizes suction and dust removal of the minerals at the entry end, and the top dust suction component 2 includes a feed ring frame 202 and two hollow surrounding dust suction plates 201. A mounting plate 206 is provided on one side of the sorting box 1, one of the hollow surrounding dust suction plates 201 is fixedly connected to the top of the mounting plate 206, and the other hollow surrounding dust suction plate 201 is fixedly connected to the top of the sorting box 1, and the dust inside the feed ring frame 202 is sucked and discharged with the help of the two mounting plates 206.

[0055] A dust collecting box 3 is provided on the top of the sorting box 1, and a feed ring frame 202 is movably connected to the interior of the sorting box 1 near the feed end, and impact rods 207 are equidistantly provided on the inner walls of both sides of the feed ring frame 202, a pump frame 208 is provided on one side of the sorting box 1, and a dust pump 204 is provided on the top of the pump frame 208, and two hollow dust suction holes 203 are equidistantly provided on the outside of the two hollow dust suction plates 201 facing the feed ring frame 202, and connecting holes are provided on the outside of the two hollow dust suction plates 201, and the same connecting pipe 205 is provided inside the two connecting holes, and the dust suction end of the dust suction pump 204 is connected to the inside of the connecting pipe 205 through a pipeline, and the dust conveying end of the dust suction pump 204 is provided with a dust conveying pipe 209, and the other end of the dust conveying pipe 209 is plugged into the inside of the dust collecting box 3.

[0056] It should be noted that before the mineral is introduced into the sorting box 1, it falls into the feed ring frame 202, and the impact rod 207 in the feed ring frame 202 collides with it to achieve initial loosening. At the same time, during the collision, the dust suction pump 204 is started. The dust suction pump 204 absorbs the dust generated by the collision through the hollow dust suction holes 203 on the dust suction plate 201. The dust generated by the vibration screening is also introduced into the dust collecting box 3 by the dust suction pump 204 to avoid dust causing environmental pollution in the surrounding area.

[0057] Before the mineral is introduced into the sorting box 1, it falls into the feed ring frame 202, and the impact rod 207 in the feed ring frame 202 collides with it to achieve initial loosening. At the same time, during the collision, the dust suction pump 204 is started, and the dust suction pump 204 absorbs the dust generated by the collision through the hollow dust suction holes 203 on the dust suction plate 201.

[0058] After the mineral falls onto the screen plate 8, during its vibration screening process, the drive motor 401 is started, and the drive motor 401 drives the electromagnetic rotor 410 to rotate, thereby rotating the mineral that slides there into the cover frame 404, and the electromagnetic rotor 410 cooperates with each matching blocking plate 403 to separate large particles from small particles in the mineral. In the subsequent vibration sorting process of the mineral, the mineral slides onto the impact arc plate 406, which collides with the impact ball 405, and further sorts the different granular minerals attached together. During the sorting process, some minerals fall below through the sieve holes on the screen plate 8, and some minerals are discharged through the guide plate 6.

[0059] Small particles of minerals fall onto the curved screen 1001 below. The impact caused by the high drop causes the hanging spring rod 1004 to be compressed. During the resetting process, the curved screen 1001 is driven to perform secondary sorting of the small particles of minerals. Finally, the sorted minerals are collected, and the operation is terminated. The above process is repeated continuously to achieve the sorting of minerals.

[0060] Second embodiment

[0061] As can be seen from the above, when the impact rod 207 is used to collide with the mineral, since the position of the impact rod 207 is fixed, the impact position and impact force of the impact rod 207 and the mineral are the same, then the impact efficiency of the impact rod 207 on the mineral is reduced, the impact effect is poor, and it is easy to be damaged; at the same time, when the dust generated after the impact of the mineral inside the feed ring frame 202 is used to remove dust and impurities, since the positions do not change, the dust hole 203 will be blocked after long-term use, thereby reducing the subsequent dust suction and discharge effect; and when the amount of large-particle minerals gradually decreases, if the bent screen 1001 still repeats the up and down vibration to impact and crush small-particle materials, the small-particle materials will be over-crushed, and the effect of the minerals that meet the requirements being laid flat on the bottom of the sorting box 1 along the bent screen 1001 will be poor, thereby causing the minerals that meet the requirements to accumulate at the bottom of the sorting box 1, reducing the subsequent material collection amount and collection effect.

[0062] In order to solve the above problems, the mineral sorting system further comprises: connecting rods 411 are hinged on the top of both sides of the sieve plate 8, the top of the connecting rod 411 is hinged to the bottom of the feed ring frame 202, the inner walls of both sides of the sorting box 1 are provided with slide grooves, and the two sides of the feed ring frame 202 are provided with sliders, and the slide grooves match the sliders, so when the sieve plate 8 vibrates up and down, the sieve plate 8 synchronously drives the feed ring frame 202 to move up and down inside the sorting box 1, and the feed ring frame 202 drives the internal impact rod 207 to vibrate up and down, and the impact rod 207 07 The impact effect of the impact force on the mineral is constantly changing, which effectively improves the impact crushing effect on the mineral. At the same time, as the feed ring frame 202 moves up and down, the gap between the feed ring frame 202 and the hollow surrounding dust suction plate 201 is constantly changing, and the dust suction and impurity removal effect of the hollow surrounding dust suction plate 201 on the feed ring frame 202 changes, thereby effectively avoiding the clogging of the dust suction hole 203 during long-term work, and improving the irregular dust suction and impurity removal of the dust inside the feed ring frame 202 by the dust suction hole 203.

[0063] The top of the magnetic plate 1002 matches the bottom of the sieve plate 8, and the magnetic plate 1002 matches the facing end of the electromagnetic vane 410. Both sides of the fixed plate 1003 are provided with elastic rods 412, and the other end of the elastic rods 412 is fixedly connected to the inner wall of the sorting box 1. The extension distance of the electric push rod 413 is inversely proportional to the power supply of the electromagnetic vane 410, that is, when the extension distance of the electric push rod 413 is larger, the power supply current of the electromagnetic vane 410 is smaller, so when the sieve plate 8 moves downward, the electric push rod 413 is larger, and the power supply current of the electromagnetic vane 410 is smaller. When the sieve plate 8 moves, the sieve plate 8 exerts a downward force on the magnetic plate 1002, and the magnetic plate 1002 squeezes the elastic rod 412 to drive the fixed plate 1003 to move downward, and the fixed plate 1003 drives the connecting spring rod 408 and the bent screen 1001 at the bottom to move downward. When the sieve plate 8 moves upward to return to its original position, the elastic force of the elastic rod 412 drives the fixed plate 1003 to move upward to return to its original position, and the fixed plate 1003 drives the connecting spring rod 408 and the bent screen 1001 at the bottom to move downward. 01 moves upward to return to its original position, and when the electromagnetic vane 410 is energized and has magnetism, the end of the electromagnetic vane 410 has the same magnetism as the side of the magnetic plate 1002 close to the electromagnetic vane 410, and the magnetic plate 1002 is driven to move away from the end of the electromagnetic vane 410 by the magnetic repulsion of the electromagnetic vane 410 on the magnetic plate 1002, and the magnetic plate 1002 drives the bottom fixed plate 1003 to squeeze the elastic rod 412 to move away from the end of the electromagnetic vane 410, and when the electromagnetic vane 410 rotates When the distance between the movable rod 409 and the magnetic plate 1002 increases, the magnetic repulsion of the electromagnetic vane 410 on the magnetic plate 1002 decreases, and the fixed plate 1003 is driven to move closer to the end of the electromagnetic vane 410 under the elastic force of the elastic rod 412. During this process, the bent screen 1001 is swung left and right inside the sorting box 1, thereby effectively shaking and screening the small particles of minerals located on the top of the bent screen 1001, thereby improving the screening effect and screening uniformity of the small particles of minerals.

[0064] When in use, first install the device according to the first embodiment, and then pour the mineral into the feed ring frame 202. The mineral collides with the impact rod 207 inside the feed ring frame 202 and further falls on the top of the screen plate 8. At the same time, the controller controls the dust suction pump 204 to start and apply suction force to the connecting pipe 205. The hollow dust suction hole 203 around the dust suction plate 201 applies suction force to the inside of the feed ring frame 202. The dust and impurities in the mineral enter the connecting pipe 205 along the dust suction hole 203 and finally reach the dust collecting box 3 for storage.

[0065] At the same time, the controller controls the driving motor 401 to start and drive the rotating rod 409 to rotate, and the rotating rod 409 drives the electromagnetic vane 410 to rotate through the electric push rod 413. At this time, since the electric push rod 413 is started and drives the electromagnetic vane 410 at the end to extend to the maximum distance, the electromagnetic vane 410 is powered off and has no magnetism. As the rotating rod 409 rotates, the electromagnetic vane 410 is squeezed and contacted with the sieve plate 8, and the sieve plate 8 moves downward under the action of the squeezing force. When the electromagnetic vane 410 is separated from the squeezing effect on the sieve plate 8, it moves upward through the limit slider 14 under the elastic force of the vibration spring rod 13 to return to its original position. The sieve plate 8 continuously vibrates up and down inside the sorting box 1, and cooperates with the impact arc plate 406 to improve the vibration crushing and screening effect of the mineral, so that the screening efficiency is higher, the screening effect is better, the operation is simple, and the stability and efficiency are high.

[0066] At the same time, when the sieve plate 8 moves downward, the top feed ring frame 202 is driven to move downward through the connecting rod 411, and the gap between the feed ring frame 202 and the hollow surrounding dust suction plate 201 increases, so that the dust suction effect of the dust suction hole 203 on the feed ring frame 202 changes, which effectively avoids the blockage of the dust suction hole 203 during long-term operation, and improves the vibration dust suction effect of the dust suction hole 203 on the inside of the feed ring frame 202. When the sieve plate 8 moves upward, the feed ring frame 202 is simultaneously driven to move upward through the connecting rod 411, and the feed ring frame 202 continuously moves up and down inside the sorting box 1 and drives the impact rod 207 to move up and down, and the impact rod 207 impacts and collides the mineral up and down, effectively improving the impact and crushing effect on the mineral.

[0067] At the same time, when the sieve plate 8 moves downward, the bottom of the sieve plate 8 exerts a downward force on the top of the magnetic plate 1002, and the magnetic plate 1002 drives the bent screen 1001 to move downward through the fixed plate 1003 and the hanging spring rod 1004. When the sieve plate 8 moves upward, the elastic force of the elastic rod 412 drives the bent screen 1001 to move upward and return to its original position, then the small particles of minerals on the top of the sieve plate 8 fall to the top of the bent screen 1001, and the small particles of material are further vibrated and screened under the up and down vibration of the bent screen 1001, thereby effectively improving the efficient screening of small particles of minerals, thereby obtaining qualified minerals.

[0068] After the first-order crushing and screening of the mineral, the above process needs to be repeated. At this time, the mineral discharged along the guide plate 6 needs to repeat the above process. At this time, due to the reduction in the overall volume of the mineral, the crushing and screening effect of the mineral needs to be reduced. The controller controls the electric push rod 413 to reduce the extension distance, and the corresponding current of the electromagnetic vane 410 increases. When the rotating rod 409 drives the electromagnetic vane 410 to rotate through the electric push rod 413, the electromagnetic vane 410 drives the sieve plate 8 to vibrate up and down inside the sorting box 1 to reduce the amplitude, and the corresponding sieve plate 8 drives the top feed ring frame 202 to move up and down to reduce the amplitude, the feed ring frame 202 drives the impact rod 207 to reduce the impact crushing effect of the mineral, and at the same time, the downward extrusion force exerted by the sieve plate 8 on the bottom magnetic plate 1002 is reduced. 8 drives the amplitude of the up and down vibration of the bent screen 1001 at the bottom to decrease, and when the electromagnetic vane 410 is facing the magnetic plate 1002 and exerts a magnetic repulsion on the magnetic plate 1002, the magnetic plate 1002 is moved away from the end of the electromagnetic vane 410 by the magnetic repulsion, and the magnetic plate 1002 drives the bent screen 1001 at the bottom to move synchronously, and when the rotating rod 409 drives the electromagnetic vane 410 to rotate and the distance between the electromagnetic vane 410 and the magnetic plate 1002 is reduced, the bent screen 1001 is driven to move in the opposite direction and return to its original position under the elastic force of the elastic rod 412, and the bent screen 1001 cooperates with its own up and down movement to perform a circular rotation inside the sorting box 1, further improving the shaking screening effect of small-particle minerals, with higher screening efficiency and better screening effect, and it is easier to obtain the required qualified minerals.

[0069] As the sorting continues, there are fewer and fewer large-particle minerals and more and more small-particle minerals. At this time, the small-particle minerals need to be spread out to improve the uniformity of the stacking of small-particle minerals inside the sorting box 1. At this time, the controller controls the electric push rod 413 to retract to the maximum distance, and the corresponding electromagnetic vane 410 has the maximum magnetism. The rotating rod 409 rotates through the electric push rod 413 to drive the electromagnetic vane 410 to rotate, and the electromagnetic vane 410 does not contact the sieve plate 8. The sieve plate 8 is in a stable state, and the feed ring frame 202 is also in a stable state. The small-particle minerals enter the top of the sieve plate 8 along the feed ring frame 202. At this time, the impact effect of the impact rod 207 on the small-particle minerals is the lowest, and the small-particle minerals on the top of the sieve plate 8 fall on the top of the bent screen 1001. At this time, the electromagnetic When the vane 410 rotates and reaches the position directly opposite to the magnetic plate 1002, the electromagnetic vane 410 exerts a magnetic repulsion force on the magnetic plate 1002 to drive the bent screen 1001 to move to the maximum distance away from the end of the electromagnetic vane 410. When the electromagnetic vane 410 continues to rotate and the distance between it and the magnetic plate 1002 increases, the elastic force of the elastic rod 412 drives the bent screen 1001 to move in the opposite direction and return to its original position. The rotating rod 409 continuously drives the electromagnetic vane 410 to rotate, and the bent screen 1001 continuously swings left and right inside the sorting box 1, further improving the shaking and spreading of small particles of minerals on the top of the bent screen 1001, thereby ensuring that qualified minerals are evenly spread on the bottom of the sorting box 1, thereby improving the collection amount and collection effect of qualified materials by the sorting box 1.

[0070] When all the minerals have been sorted, new minerals continue to be poured into the feed ring frame 202, and the above process is repeated, thereby continuously achieving efficient sorting of the minerals.

[0071] The device not only realizes the collision, crushing and sorting of minerals, but also realizes secondary screening with the help of the screen plate 8 and the bent screen 1001, so the sorting efficiency is higher and the sorting accuracy is better; and in the sorting process, the collision and crushing effect and the subsequent up and down vibration sorting amplitude can be adjusted according to the volume of the mineral, so it has stronger adaptability, higher stability and higher sorting accuracy; and when all the minerals are small particles, the bending screen 1001 is used to shake to improve the paving effect of qualified minerals, so the recovery amount is higher and the uniformity is better; at the same time, the gap between the feed ring frame 202 and the hollow surrounding dust suction plate 201 can be adjusted by itself, so that the impact crushing effect is better, and the dust suction and impurity removal adaptability and blockage clearing are stronger.

[0074] Step 1: Before the mineral is introduced into the sorting box 1, the top dust collection component 2 crushes and dusts the mineral;

[0075] Step 2: After the mineral falls onto the sieve plate 8, the rotating rod 409 rotates and drives the sieve plate 8 to rotate, and the mineral on the top of the sieve plate 8 falls downward onto the top of the bent screen 1001;

[0076] Step three: When the volume of the mineral continues to decrease, the controller controls the electric push rod 413 to drive the electromagnetic vane 410 to move closer to the end of the rotating rod 409, the vibration amplitude of the screen plate 8 decreases, the current of the electromagnetic vane 410 increases, and the magnetic plate 1002 drives the bent screen 1001 to move away from the electromagnetic vane 410. The distance increases.

[0077] By further limiting the method, the screening effect and efficiency of the minerals are improved, the adaptability is stronger, the stability is higher, the operation is simple, and the stability and efficiency are high.
