Description

Technical Field

[0001] This invention relates to the field of metal ore crushing technology, specifically to a metal ore pretreatment device and system. Background Technology

[0002] In the pretreatment of metal ore, jaw crushers are crucial for crushing the ore. This is because jaw crushers possess powerful crushing capabilities and adaptability, handling ores of varying hardness and particle size to the appropriate particle size required for subsequent processing steps. Crushing increases the ore's liberation degree, facilitating subsequent grinding and beneficiation operations, thereby improving metal recovery rates and concentrate grades. Furthermore, jaw crushers have a simple structure and reliable operation, bringing users significant economic benefits and reducing production costs.

[0003] Chinese patent document CN113856797B discloses a jaw crusher, including a base and a crushing chamber. The base is bolted to the bottom outer wall of the crushing chamber. A stationary jaw is fixed to one side inner wall of the crushing chamber by screws. A roller groove is formed on the top outer wall of the stationary jaw, and a guide mechanism is provided on the inner wall of the roller groove. A receiving groove is formed on one side outer wall of the stationary jaw, and a spring plate is fixed to the inner wall of the receiving groove by screws. A flat plate is fixed to one side outer wall of the spring plate by screws, and the flat plate is inserted into the inner wall of the receiving groove. A biting groove is formed on one side outer wall of the stationary jaw, and a toothed plate is fixed to the inner wall of the biting groove by screws. A slide rail is formed on one side outer wall of the crushing chamber. A slider is inserted into the wall. Limit springs are fixed to the top and bottom outer walls of the slider with screws. One end of the limit spring is fixed to the inner wall of the slide rail with screws. A sliding hole is formed on the outer wall of the slider, and a sliding rod is inserted into the inner wall of the sliding hole. A base block is fixed to one end of the sliding rod with screws. A support spring is fixed to one side of the outer wall of the base block with screws. The support spring is sleeved on the outer wall of the sliding rod, and one end of the support spring is fixedly connected to one side of the outer wall of the slider with screws. A movable jaw is fixed to one end of the sliding rod with screws. A limit mechanism is provided on the outer wall of the movable jaw. A cooling groove is formed on the outer wall of the movable jaw, and a cooling mechanism is provided on the inner wall of the cooling groove. A driving mechanism is provided on the top outer wall of the base.

[0004] During operation, the stone is poured from top to bottom through the opening of the crushing chamber. The motor is started, driving the pulley to rotate. Through the action of the eccentric guide wheel, the moving jaw produces a movement trajectory similar to oral engagement. When the ore falls and hits the spring plate, it is bounced away. The spring plate bounces the ore towards the stationary jaw, causing the ore to roll and fill the gap between the stationary and moving jaws through the combination of bouncing and its own gravity. When the ore lands on the outer wall of the top of the stationary jaw, it rolls down along the guide roller on the outer wall of the stationary jaw. Under the action of the tension spring, the scraper is pushed outward, and the trapezoidal groove limits the extension distance of the scraper. As the ore rolls down, the scraper scratches the outer surface of the ore. During the crushing process, when the plate is under great pressure, it retracts into the inner wall of the receiving trough. At this time, the toothed plate protrudes outward, thus crushing the ore.

[0005] However, the above-mentioned patent documents still have the following shortcomings: After the metal ore falls between the moving jaw plate and the fixed jaw plate, due to its shape and position, when the moving jaw plate approaches the fixed jaw plate to squeeze, some metal ore is prone to cracking but not completely broken and separated. At this time, the moving jaw plate and the fixed jaw plate need to work again to perform secondary crushing, which reduces the efficiency of metal ore pretreatment. Summary of the Invention

[0006] This invention provides a metal ore pretreatment device and system, which aims to solve the problem in related technologies where some metal ores are prone to cracking but not completely broken and separated when the moving jaw plate is close to the fixed jaw plate for extrusion. In this case, the moving jaw plate and the fixed jaw plate need to work together again for secondary crushing, which reduces the efficiency of metal ore pretreatment.

[0007] The metal ore pretreatment apparatus of the present invention includes a frame, a drive mechanism, and a fixed jaw plate. The fixed jaw plate is connected within the frame. The drive mechanism includes a drive component and a moving part. The moving part is rotatably connected to the drive component. The drive component is installed within the frame and can drive the moving part to reciprocate. The apparatus also includes a movable jaw component and a pushing mechanism. The movable jaw component includes a support component, a movable jaw plate, and a locking component. The support component and the locking component are both connected to the moving part. The movable jaw plate is slidably connected between the support component and the locking component. The moving part can drive the movable jaw plate to reciprocate and cooperate with the fixed jaw plate to crush the metal ore. The pushing mechanism includes a second drive source, a transmission component, and a pushing component. The second drive source is connected to the frame. The pushing component is installed on the moving part. The transmission component is connected between the second drive source and the pushing component. The pushing component is connected to the movable jaw plate. The second drive source drives the transmission component so that the transmission component drives the pushing component to run, thereby driving the movable jaw plate to reciprocate laterally.

[0008] When pre-processing metal ore, the metal ore is first placed into the frame so that it is positioned between the fixed jaw plate and the moving jaw. The drive mechanism is then activated, and the drive unit drives the moving part to reciprocate in the direction of approaching or moving away from the fixed jaw plate. As the moving part reciprocates, it drives the moving jaw to reciprocate in the same direction, thereby crushing the metal ore located between the fixed jaw plate and the moving jaw. Simultaneously, the second drive source is activated, which drives the transmission component to run. When the transmission component runs, it drives the pusher component to push the moving jaw plate to reciprocate laterally. The reciprocating lateral movement of the moving jaw plate generates shearing force on the metal ore, further crushing it. This effectively avoids the phenomenon of the metal ore cracking but not being completely crushed and separated, thus improving the pre-processing efficiency of the metal ore.

[0009] Preferably, the driving component includes an eccentric shaft, a flywheel, a pulley, a first driving source, and a transmission belt. The eccentric shaft is rotatably connected to the frame, the flywheel is connected to one end of the eccentric shaft, the pulley is connected to the other end of the eccentric shaft, the moving part is rotatably connected to the eccentric shaft, the first driving source is connected to the frame, and the transmission belt is connected between the first driving source and the pulley.

[0010] The starting drive source can drive the pulley to rotate via the transmission belt, which in turn drives the eccentric shaft to rotate. When the eccentric shaft rotates, it drives the moving part to oscillate back and forth, thus providing power for the oscillation of the moving part. The flywheel can store and release energy to balance the speed fluctuations caused by load changes during the operation of the equipment, ensuring smoother operation of the metal ore pretreatment device, reducing drastic changes in the load of the drive source, thereby improving overall work efficiency and extending the service life of the equipment.

[0011] Preferably, the drive mechanism further includes a mounting bracket and a rib plate, the mounting bracket being connected within the frame, and the rib plate being installed between the moving part and the mounting bracket.

[0012] The ribs effectively disperse the enormous squeezing and impact forces that the moving part experiences when reciprocating to crush metal ore, preventing the moving part from deforming and cracking due to concentrated stress. At the same time, they also improve the overall structural stability of the moving part, preventing fatigue damage under long-term alternating loads and thus extending the service life of the moving part. The moving jaw is installed on the moving part.

[0013] Preferably, the movable part is provided with an installation port and multiple installation slots, and the pusher is installed in the installation port.

[0014] The installation port facilitates the installation of the pusher and allows the pusher to drive the moving jaw plate to reciprocate laterally under the guidance of the support and the fixed jaw plate.

[0015] Preferably, each of the plurality of mounting slots is equipped with a roller assembly, the roller assembly comprising a plurality of rollers, the circumferential surface of the rollers being in contact with the moving jaw plate.

[0016] The roller assembly reduces friction between the moving part and the moving jaw plate, enhancing the smoothness of the reciprocating lateral movement of the moving jaw plate.

[0017] Preferably, the circumferential surface of the roller is in contact with the inner wall of the mounting groove.

[0018] By having the rollers contact the inner wall of the mounting groove, support can be provided for the rollers to prevent damage to the connection between the rollers and the mounting groove when subjected to compressive force.

[0019] Preferably, the moving jaw plate is provided with a sliding groove on the side near the moving part.

[0020] The groove is designed to allow the pusher to drive the moving jaw plate to reciprocate laterally under the guidance of the support and the fixed jaw plate.

[0021] Preferably, the pusher includes a connecting arm, a second rotating part, and a pusher. The connecting arm is connected to the mounting port, the second rotating part is rotatably connected to the connecting arm, and the pusher is connected to the second rotating part. The second rotating part can rotate to drive the pusher to move along a circular trajectory. The second rotating part is slidably connected to the groove.

[0022] When the rotating part rotates, it drives the pushing part to move along a circular trajectory. The movement of the pushing part along the circular trajectory can drive the moving jaw plate to move back and forth under the guidance of the supporting part and the locking part, applying shearing force to the metal ore and further crushing the metal ore.

[0023] Preferably, the transmission component includes a support arm, a rotating part one, a universal joint, and gears. The support arm is connected inside the frame, the rotating part one is rotatably connected to the support arm, the universal joint is connected between the rotating part one and the rotating part two, and there are two gears. The two gears are respectively connected to the output ends of the rotating part one and the drive source two, and the two gears are meshed together.

[0024] The second drive source drives two gears to mesh and drive the first rotating part to rotate. When the first rotating part rotates, it drives the second rotating part to rotate through the universal joint. When the second rotating part rotates, it drives the pusher to move along a circular trajectory. Thus, the pusher pushes the moving jaw plate to move back and forth under the guidance of the support and locking parts, providing shearing force for crushing metal ore. Moreover, through the universal joint, the second rotating part can still rotate when it follows the moving part to swing back and forth.

[0025] The present invention also provides a metal ore pretreatment system, including a metal ore pretreatment device, an adjusting component connected inside the frame, and the adjusting component being connected to a moving part.

[0026] After the drive mechanism is started, the moving part reciprocates in the direction of approaching or moving away from the fixed jaw plate through the drive component, thereby driving the moving jaw to swing synchronously, thus crushing the metal ore located between the fixed jaw plate and the moving jaw. At the same time, the second drive source is turned on, causing the transmission component to operate and pushing the moving jaw plate to move laterally reciprocally. With the help of this shearing force, the metal ore is further crushed, effectively preventing the ore from cracking but not completely separating, thus improving the pre-processing efficiency of the metal ore. The adjusting component can not only accurately control the gap between the moving jaw and the fixed jaw plate to effectively adjust the particle size of the crushed metal ore, but also compensate in time when the gap between the moving jaw or the fixed jaw plate increases due to wear, ensuring the stability of the output particle size. In addition, the adjusting component also has the function of limiting the swing amplitude of the moving jaw, effectively preventing its excessive swing, thereby avoiding equipment failure.

[0027] The beneficial effects of this invention are:

[0028] 1. The moving part is driven by the drive unit to reciprocate in the direction of approaching or moving away from the fixed jaw plate. When the moving part reciprocates, it simultaneously drives the moving jaw to reciprocate, thereby crushing the metal ore located between the fixed jaw plate and the moving jaw. At the same time, the second drive source is activated, which drives the transmission component to run. When the transmission component runs, it drives the pusher component to push the moving jaw plate to reciprocate laterally. The reciprocating laterally movement of the moving jaw plate generates shear force on the metal ore, further crushing the metal ore. This effectively avoids the phenomenon of metal ore cracking but not being completely crushed and separated, and improves the pre-processing efficiency of metal ore.

[0029] 2. The roller assembly converts the sliding friction between the moving part and the moving jaw plate into rolling friction, which not only significantly reduces the resistance loss during their relative movement, but also significantly enhances the stability and smoothness of the reciprocating lateral movement of the moving jaw plate. This effectively avoids problems such as motion jamming and trajectory deviation caused by excessive frictional resistance, ensuring the continuity and stability of the crushing operation. At the same time, the rollers of the roller assembly form a close contact with the inner wall of the mounting groove. With the help of the rigid load-bearing structure of the mounting groove, the alternating extrusion pressure borne by the moving jaw plate during material crushing is evenly distributed to the contact surface of the rollers and the mounting groove. This avoids the extrusion pressure being concentrated at the connection node between the rollers and the mounting groove, thereby reducing the risk of deformation, cracking, loosening, and other damage at this connection point due to stress concentration, and extending the overall service life of the roller assembly and the moving jaw plate.

[0030] 3. By using transmission components, indirect power transmission between drive source two and pusher component is realized, so that drive source two does not need to be directly installed on the moving part which is prone to vibration, and can provide stable and continuous power to pusher component. This effectively isolates the vibration generated by the moving part during operation and prevents these vibrations from being directly transmitted to drive source two, thereby significantly reducing equipment wear and potential failure risks caused by long-term vibration, greatly extending the service life of drive source two, improving the reliability and maintenance convenience of the entire mechanism, and the use of universal joints allows rotating part two to maintain normal rotation when it follows the reciprocating swing of the moving part.

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] like Figures 1 to 8 As shown, the metal ore pretreatment device of the present invention includes a frame 1, a drive mechanism 2, a movable jaw 3, a fixed jaw plate 4, and a push mechanism 5. The drive mechanism 2 is installed inside the frame 1, the movable jaw 3 is installed on the drive mechanism 2, and the fixed jaw plate 4 is installed inside the frame 1. The frame 1 provides a limiting space for the crushing of metal ore, so that the metal ore entering the frame 1 is located between the movable jaw 3 and the fixed jaw plate 4. The drive mechanism 2 can drive the movable jaw 3 to swing back and forth in the direction of approaching or moving away from the fixed jaw plate 4, thereby crushing the metal ore. The push mechanism 5 is installed on the frame 1, and the movable jaw 3 is connected to the push mechanism 5. The push mechanism 5 can drive the movable jaw 3 to move back and forth laterally, so that the movable jaw 3 and the fixed jaw plate 4 squeeze the metal ore while applying shear force to the metal ore, further crushing the metal ore. This effectively avoids the phenomenon of metal ore cracking but not being completely crushed and separated, and improves the pretreatment efficiency of metal ore.

[0043] During the pretreatment of metal ore, the metal ore is first fed into the frame 1, and the frame 1 limits the metal ore so that it is positioned between the moving jaw 3 and the fixed jaw plate 4. Then, the drive mechanism 2 is activated, which drives the moving jaw 3 to swing back and forth in the direction of approaching or moving away from the fixed jaw plate 4, thereby squeezing the metal ore and crushing it. At the same time, the push mechanism 5 is activated, which drives the moving jaw 3 to move back and forth laterally, thereby applying shearing force to the metal ore and further crushing it, preventing the metal ore from cracking but not being completely crushed and separated.

[0044] like Figures 1 to 4 As shown, the frame 1 includes a protective shell 11, a base 12, a storage box 13, and a hopper 14. The base 12 is connected to the bottom of the protective shell 11. The protective shell 11 provides a limiting space for the crushing of metal ore and prevents the metal ore from splashing outwards during crushing. The storage box 13 is inserted into the base 12. The storage box 13 can shield the bottom of the frame 1 when transporting the metal ore pretreatment device and can also collect the metal ore that falls from the frame 1 during transportation. The hopper 14 is installed on the top of the protective shell 11 and is used to guide the metal ore so that the metal ore is transported between the moving jaw 3 and the fixed jaw plate 4.

[0045] During the pretreatment of metal ore, the metal ore is first conveyed into the protective shell 11 through the hopper 14. The protective shell 11 not only serves to guide and limit the movement, ensuring that the metal ore can accurately enter the crushing area between the moving jaw 3 and the fixed jaw plate 4, but also provides necessary safety for the entire crushing process. Subsequently, the drive mechanism 2 is activated, which drives the moving jaw 3 to periodically swing back and forth around the fixed jaw plate 4, so that the moving jaw 3 and the fixed jaw plate 4 form a constantly changing space. When the space shrinks, the metal ore located between the moving jaw 3 and the fixed jaw plate 4 is crushed by strong extrusion force. As the space increases, small pieces of ore that have reached the required particle size are discharged outward. During the crushing process of the metal ore, the protective shell 11 shields the metal ore to prevent the fragments from splashing outward during the crushing process.

[0046] like Figures 1 to 6 As shown, the fixed jaw plate 4 is connected to the front side of the inner wall of the protective shell 11. The drive mechanism 2 includes a drive component, a moving part 26, a mounting frame 27, and a rib plate 28. The drive component is mounted on the protective shell 11, and the moving part 26 is mounted on the drive component. The drive component can drive the moving part 26 to swing back and forth in the direction of approaching or moving away from the fixed jaw plate 4. The mounting frame 27 is connected inside the protective shell 11. The rib plate 28 is installed between the moving part 26 and the mounting frame 27. When the moving part 26 moves back and forth to crush metal ore, it will be subjected to huge extrusion and impact forces. The rib plate 28 can effectively disperse these stresses, prevent the moving part 26 from deforming and cracking due to concentrated force, and at the same time improve the overall structural stability of the moving part 26, avoid fatigue damage under long-term alternating loads, and thus extend the service life of the moving part 26. The moving jaw component 3 is mounted on the moving part 26.

[0047] When pre-processing metal ore, the moving part 26 is driven by the driving component to swing back and forth in the direction of approaching or moving away from the fixed jaw plate 4. At the same time, the moving part 26 drives the moving jaw 3 to swing back and forth synchronously, so that the metal ore is crushed under the action of the moving jaw 3 and the fixed jaw plate 4.

[0048] Continue to refer to Figures 1 to 6As shown, the driving components include an eccentric shaft 21, a flywheel 22, a pulley 23, a drive source 24, and a transmission belt 25. The eccentric shaft 21 is rotatably connected to the protective shell 11. The flywheel 22 is connected to one end of the eccentric shaft 21, and the pulley 23 is connected to the other end of the eccentric shaft 21. The moving part 26 is rotatably connected to the eccentric shaft 21. The drive source 24 is connected to the base 12. The drive source 24 is a motor, and a transmission wheel is installed on the output end of the motor. The transmission belt 25 connects the transmission wheel and the pulley 23. The drive source 24 is activated. 24 can drive the transmission belt 25, pulley 23 and transmission wheel to rotate the eccentric shaft 21. When the eccentric shaft 21 rotates, it can drive the moving part 26 to reciprocate, thereby providing power for the reciprocating oscillation of the moving jaw 3. The flywheel 22 can store and release energy to balance the speed fluctuation caused by load changes during the operation of the equipment, ensure that the operation of the metal ore pretreatment device is more stable, reduce the drastic changes in the load of the drive source 24, thereby improving the overall working efficiency and extending the service life of the equipment.

[0049] After the metal ore is transported into the protective shell 11, the drive source 24 is activated to drive the transmission belt 25, pulley 23 and transmission wheel to rotate the eccentric shaft 21. When the eccentric shaft 21 rotates, it drives the moving part 26 to reciprocate. The moving part 26 drives the moving jaw 3 to reciprocate in the direction of approaching or moving away from the fixed jaw plate 4. After the metal ore falls between the moving jaw 3 and the fixed jaw plate 4, the metal ore is crushed by the moving jaw 3 and the fixed jaw plate 4.

[0050] like Figures 2 to 8 As shown, the movable jaw component 3 includes a support part 31, a movable jaw plate 32, and a locking part 33. Both the support part 31 and the locking part 33 are connected to the moving part 26. The movable jaw plate 32 is slidably connected between the support part 31 and the locking part 33. By limiting the movable jaw plate 32 through the support part 31 and the locking part 33, the movable jaw plate 32 can be prevented from falling off the moving part 26. The pushing mechanism 5 can drive the movable jaw plate 32 to reciprocate laterally under the guidance of the support part 31 and the locking part 33, thereby applying shearing force to the metal ore and further crushing it, effectively preventing the metal ore from cracking but not being completely crushed and separated. This phenomenon improves the pretreatment efficiency of metal ore. The moving part 26 is provided with multiple mounting slots 262, and each mounting slot 262 is rotatably connected to a roller assembly 210. The roller assembly 210 includes multiple rollers, and the circumferential surfaces of the rollers contact the moving jaw plate 32 and the inner wall of the mounting slot 262 respectively. The roller assembly 210 can reduce the friction between the moving part 26 and the moving jaw plate 32, and enhance the smoothness of the reciprocating lateral movement of the moving jaw plate 32. The contact between the rollers and the inner wall of the mounting slot 262 can provide support for the rollers, so as to avoid damage to the connection between the rollers and the mounting slot 262 after being subjected to extrusion pressure.

[0051] When the moving part 26 drives the moving jaw 3 to swing back and forth toward or away from the fixed jaw plate 4, the pushing mechanism 5 is activated. The pushing mechanism 5 drives the moving jaw plate 32 to move back and forth under the guidance of the support part 31 and the locking part 33. During the back and forth movement of the moving jaw plate 32, shearing force is applied to the metal ore to further crush the metal ore and avoid the phenomenon that the metal ore cracks but is not completely crushed and separated.

[0052] like Figures 2 to 8 As shown, the moving part 26 is provided with a mounting port 261. The pushing mechanism 5 includes a second drive source 51, a transmission component 52, and a pushing component 53. The second drive source 51 is connected to the protective shell 11. The pushing component 53 is installed in the mounting port 261. The pushing component 53 can drive the moving jaw plate 32 to reciprocate laterally under the guidance of the support part 31 and the locking part 33. The transmission component 52 is connected between the second drive source 51 and the pushing component 53. The second drive source 51 is a motor, which can provide power for the operation of the pushing component 53. This enables indirect power transmission between drive source 21 and pusher 53, allowing drive source 21 to provide stable and continuous power to pusher 53 without being directly mounted on the moving part 26 which is prone to vibration. It effectively isolates the vibration generated by the moving part 26 during operation, preventing these vibrations from being directly transmitted to drive source 21. This significantly reduces equipment wear and potential failure risks caused by long-term vibration, greatly extends the service life of drive source 21, and improves the reliability and maintenance convenience of the entire mechanism.

[0053] Continue to refer to Figures 2 to 8 As shown, the movable jaw plate 32 is provided with a groove 321 on the side near the moving part 26. The pushing member 53 includes a connecting arm 531, a rotating part 532, and a pushing part 533. The connecting arm 531 is connected to the mounting port 261. The rotating part 532 is rotatably connected to the connecting arm 531. The pushing part 533 is connected to the rotating part 532 and is inserted into the groove 321. The driving source 51 can drive the rotating part 532 to rotate through the transmission member 52. When the rotating part 532 rotates, it can drive the pushing part 533 to move along a circular trajectory. Thus, the pushing part 533 pushes the movable jaw plate 32 to reciprocate laterally under the guidance of the support part 31 and the locking part 33, thereby providing shearing force for the crushing of metal ore. This effectively avoids the phenomenon of metal ore cracking but not being completely crushed and separated, and improves the pre-processing efficiency of metal ore.

[0054] Continue to refer to Figures 2 to 8As shown, the transmission component 52 includes a support arm 521, a rotating part 522, a universal joint 523, and a gear 524. The support arm 521 is connected inside the protective shell 11. The rotating part 522 is rotatably connected to the support arm 521. The universal joint 523 is connected between the rotating part 522 and the rotating part 532. When the rotating part 522 rotates, it can drive the rotating part 532 to rotate through the universal joint 523. The universal joint 523 can also drive the rotating part 532 to rotate when the rotating part 532 follows the reciprocating swing of the moving part 26. There are two gears 524. The two gears 524 are respectively connected to the output end of the rotating part 522 and the drive source 51, and the two gears 524 are meshed together.

[0055] The second drive source 51 drives the two gears 524 to mesh and drive the first rotating part 522 to rotate. When the first rotating part 522 rotates, it drives the second rotating part 532 to rotate through the universal joint 523. When the second rotating part 532 rotates, it drives the push part 533 to move along a circular trajectory. Thus, the push part 533 pushes the moving jaw plate 32 to reciprocate laterally under the guidance of the support part 31 and the locking part 33, providing shearing force for crushing metal ore.

[0056] Working principle:

[0057] Metal ore is fed into the frame 1 so that it is positioned between the moving jaw 3 and the fixed jaw plate 4. The drive source 24 is activated to drive the transmission belt 25, pulley 23, and drive wheel to rotate the eccentric shaft 21. When the eccentric shaft 21 rotates, it drives the moving part 26 to reciprocate. The moving part 26 drives the moving jaw 3 to reciprocate in the direction of approaching or moving away from the fixed jaw plate 4. The moving jaw 3 and the fixed jaw plate 4 crush the metal ore. During this process, the flywheel 22 can store and release energy to balance the speed fluctuations caused by load changes during the operation of the equipment, ensuring smoother operation of the metal ore pretreatment device and reducing drastic changes in the load of the drive source 24.

[0058] The second drive source 51 drives the two gears 524 to mesh and drive the first rotating part 522 to rotate. When the first rotating part 522 rotates, it drives the second rotating part 532 to rotate through the universal joint 523. When the second rotating part 532 rotates, it drives the push part 533 to move along a circular trajectory. Thus, the push part 533 pushes the moving jaw plate 32 to reciprocate laterally under the guidance of the support part 31 and the locking part 33, providing shearing force for crushing metal ore.

[0059] like Figures 1 to 8As shown, the present invention also provides a metal ore pretreatment system, including the above-mentioned metal ore pretreatment device, and further including an adjusting member 29. The adjusting member 29 is installed between the moving part 26 and the mounting frame 27. The adjusting member 29 can control the gap between the moving jaw 3 and the fixed jaw plate 4, thereby adjusting the particle size of the crushed metal ore. At the same time, when the moving jaw 3 or the fixed jaw plate 4 is worn and the gap becomes larger, the adjusting member 29 can also compensate for the gap to ensure the stability of the output particle size. In addition, it can also help limit the swing amplitude of the moving jaw 3 to avoid excessive swing of the moving jaw 3 and equipment failure.

[0060] The adjusting component 29 is a pull rod spring type adjusting structure. The adjusting component 29 consists of a pull rod, a pressure spring, an adjusting nut, a locking nut, and a hinge pin. One end of the pull rod is hinged to the moving part 26 through the pin, and the other end passes through the mounting bracket 27 and is flexibly connected to the mounting bracket 27 through the adjusting nut. The pressure spring is fitted on the outside of the pull rod, and the two ends of the pressure spring press against the mounting bracket 27 and the adjusting nut, respectively.

[0061] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
