Description

Technical Field

[0001] The invention relates to the technical field of stone crushing, in particular to a jaw crusher and a method for preventing stone crushing and tumbling. Background Art

[0002] Jaw crusher is mainly used for medium and fine crushing of ore, coal or other medium-strength materials. Its crushing method is flexural extrusion type, relying on two wear-resistant jaw plates to crush the materials.

[0003] Its working principle is that the movable jaw plate makes periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separating, the material enters the crushing chamber and the finished product is discharged from the bottom; when approaching, the material loaded between the two jaw plates is squeezed, bent and split to be crushed.

[0004] Existing crushers usually only have one moving jaw plate, which leads to low efficiency. If the two jaw plates are driven to move together and interact with each other, when the two jaw plates are driven to move by the eccentric rod, since the eccentricity cannot be changed, the contact area of ​​the two jaw plates acting on the stone in a single staggered up and down movement remains unchanged. During crushing, the jaw plate may provide a certain reaction force to the stone, causing the stone to roll upward, resulting in poor crushing effect. Summary of the invention

[0025] A jaw crushing method for preventing stone from tumbling during crushing comprises the following steps:

[0026] Step 1: Add the stone between the inclined jaw plate and the vertical jaw plate;

[0027] Step 2: Under the action of the driving assembly, the active crushing mechanism and the driven crushing mechanism are controlled to move, so as to drive the inclined jaw plate and the vertical jaw plate to perform reciprocating alternating motion in the vertical direction;

[0028] Step 3: When the active crushing mechanism moves, it will also drive the inclined jaw plate to move in the horizontal direction. At the same time, the driven crushing mechanism will control the vertical jaw plate to move in the horizontal direction through the follow-up pushing mechanism, so that the inclined jaw plate and the vertical jaw plate move back and forth in the direction of approaching or moving away from each other to perform the crushing action on the stone;

[0030] Compared with the prior art, the beneficial effect of the present invention is that the present invention can provide a double force on the stone through the cooperation of the inclined jaw plate and the vertical jaw plate to increase the crushing effect on the stone. Specifically, under the action of the driving component, the movement of the active crushing mechanism and the driven crushing mechanism is controlled. When the active crushing mechanism moves, the inclined jaw plate is controlled to move in the vertical direction by the crushing control component, and at the same time, it makes a reciprocating swing motion in the horizontal direction. At the same time, when the driven crushing mechanism moves, the vertical jaw plate is controlled to move in the vertical direction by the follow-up pushing mechanism, and at the same time, it reciprocates in the horizontal direction. The vertical jaw plate and the inclined jaw plate move in an alternating manner in the vertical direction, and move closer to or away from each other in the horizontal direction, thereby realizing the double force on the stone to increase the crushing effect. The stroke of the inclined jaw plate and the vertical jaw plate in the vertical direction can be adjusted according to the stone crushing situation to change the double friction force applied to the stone, thereby ensuring that the stone always has a downward force during the crushing process, thereby ensuring that the stone does not roll and reducing the generation of dust.

[0031] After the stone is crushed and dropped, compared with the traditional unilateral movement, the vertical jaw plate and the inclined jaw plate can not only improve the crushing efficiency, but also speed up the discharge rate of the stone after crushing, thereby avoiding the problem of excessive overall load of the device due to stone accumulation in the crushing chamber.

[0032] Through the dual adjustment of the cylinder and the first screw rod, it is possible to achieve multiple adjustment effects and increase the adjustment range, thereby increasing the adjustment range of the stone crushing degree. Under the dual support of the connecting rod and the pulling rod, the supporting force of the inclined support plate can be increased, thereby avoiding the problem of breaking of the connecting rod or the pulling rod due to excessive reaction force on stone crushing when the connecting rod or the pulling rod acts on the inclined support plate.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0047] See also Figures 1 to 11 In an embodiment of the present invention, a jaw crusher for preventing stone material from tumbling after crushing comprises:

[0048] A frame structure 1, and a horizontal plate 2 fixedly mounted on the frame structure 1;

[0049] Also includes:

[0050] A driving assembly is arranged on the frame structure 1, an active crushing mechanism connected to the driving assembly is arranged on the transverse plate 2, and an inclined jaw plate 11 is connected to the active crushing mechanism;

[0051] A driven crushing mechanism is arranged on the frame structure 1 and connected to the driving assembly, the driven crushing mechanism is connected with a vertical jaw plate 27, and the driving assembly can drive the active crushing mechanism and the driven crushing mechanism to move, so as to control the inclined jaw plate 11 and the vertical jaw plate 27 to make reciprocating and staggered movements in the vertical direction;

[0052] A follow-up pushing mechanism is arranged on the frame structure 1 and connected to the driven crushing mechanism, and the follow-up pushing mechanism can drive the vertical jaw plate 27 to move toward or away from the inclined jaw plate 11 when the driven crushing mechanism moves;

[0053] A crushing regulating component is arranged on the transverse plate 2 and connected to the active crushing mechanism. The crushing regulating component can adjust the movement stroke of the inclined jaw plate 11 through the active crushing mechanism.

[0054] Specifically, the inclined jaw plate 11 and the vertical jaw plate 27 are combined with each other to form a crushing chamber. When crushing stones, the stones can be added into the crushing chamber, the driving component works, and the active crushing mechanism and the driven crushing mechanism are driven to move. Under the action of the active crushing mechanism, the inclined jaw plate 11 is controlled to reciprocate in the horizontal and vertical directions. Under the action of the driven crushing mechanism, the vertical jaw plate 27 is controlled to move in the horizontal and vertical directions through the follow-up pushing mechanism, and the inclined jaw plate 11 and the vertical jaw plate 27 will move toward or away from each other when they move in the horizontal direction to increase the crushing strength of the stones. When the inclined jaw plate 11 and the vertical jaw plate 27 move in the vertical direction, they reciprocate and staggered to increase the friction against the stones, ensuring that the stones will not tumble during crushing, thereby reducing the generation of dust. If it is necessary to adjust the size of stone crushing, under the action of the crushing control component, the movement stroke of the inclined jaw plate 11 is adjusted by the active crushing mechanism to adjust the size of stone crushing.

[0055] The driving assembly includes a motor 3 fixedly mounted on the frame structure 1, a first rotating rod 6 is rotatably mounted on the frame structure 1, a driven pulley 5 is fixed to the end of the first rotating rod 6, and a transmission belt 4 connected to the output shaft of the motor 3 is sleeved on the driven pulley 5.

[0056] In detail, when the stone needs to be crushed, the active crushing mechanism needs to be controlled to move. At this time, the motor 3 works and drives the driven pulley 5 to rotate through the transmission belt 4, thereby driving the first rotating rod 6 to rotate. Under the action of the first rotating rod 6, the active crushing mechanism is driven to move to crush the stone.

[0057] Preferably, a driving pulley is installed on the output shaft of the motor 3, and the transmission belt 4 is sleeved on the driving pulley and the driven pulley 5. When crushing stones, the required crushing pressure is relatively large, so the load of the motor 3 is relatively large. However, the rotation radius of the driven pulley 5 is much larger than the rotation radius of the driving pulley. Therefore, under the action of the driving pulley, the torque and moment of the transmission system can be increased while reducing the power of the motor 3, thereby improving the transmission efficiency, reducing costs, extending the service life of the equipment, and enhancing the reliability of the equipment, so as to achieve driving a larger load under a smaller torque, so as to ensure that the motor 3 will not be damaged due to excessive load when crushing stones.

[0058] The active crushing mechanism includes a first eccentric rod 7 installed on the frame structure 1, a first screw rod 8 symmetrically arranged is rotatably installed on the first eccentric rod 7, a first threaded sleeve 9 threadably matched with the first screw rod 8 is movably installed on the first screw rod 8, and the first threaded sleeve 9 is fixedly connected to the first rotating rod 6; it also includes an inclined support plate 10 sleeved on the first eccentric rod 7, the inclined support plate 10 is fixedly connected to the inclined jaw plate 11, and a pull rod assembly connected to the inclined support plate 10 is provided on the cross plate 2, wherein the pull rod assembly includes a rotating sleeve 16 rotatably installed on the cross plate 2, a limiting ring 1601 is fixed at the end of the rotating sleeve 16, a pull rod 17 hinged to the inclined support plate 10 is slidably installed in the rotating sleeve 16, and a first spring 18 abutting against the limiting ring 1601 is sleeved on the pull rod 17.

[0059] It should be noted that, in the initial state, the first threaded sleeve 9 is located at the eccentric position of the first eccentric rod 7. Under the action of the first eccentric rod 7, the inclined support plate 10 is located at the end of the stroke toward the bottom of the frame structure 1, and the first spring 18 is in a compressed state. Under the action of the pull rod 17, the end of the inclined support plate 10 away from the first eccentric rod 7 is located at the end of the stroke toward the vertical jaw plate 27. When it is necessary to crush the stone, the stone can be added into the crushing chamber. Under the action of the first rotating rod 6, the first eccentric rod 7 is driven to rotate eccentrically by the first threaded sleeve 9 and the first screw rod 8, thereby driving the inclined support plate 10 to move, so that the inclined jaw plate 11 moves. When the inclined jaw plate 11 moves in the direction away from the bottom of the frame structure 1, under the action of the crushing control component, the end of the inclined support plate 10 away from the first eccentric rod 7 is swung toward the vertical jaw plate 27 to pass The inclined jaw plate 11 and the vertical jaw plate 27 cooperate to crush the stone. The inclined support plate 10 will also drive the pull rod 17 to move, and drive the rotating sleeve 16 to rotate while compressing the first spring 18. When the inclined support plate 10 and the inclined jaw plate 11 move to the end of the stroke toward the bottom of the frame structure 1, the distance between the inclined jaw plate 11 and the vertical jaw plate 27 is the smallest. Under the action of the inclined jaw plate 11, the stone in the crushing chamber is squeezed and rubbed, thereby achieving a crushing effect. The first rotating rod 6 continues to move to control the inclined support plate 10 and the inclined jaw plate 11 to move toward the initial position. The first spring 18 is elastically released, so that the end of the inclined support plate 10 away from the first eccentric rod 7 is reset, so that the distance between the inclined jaw plate 11 and the vertical jaw plate 27 is increased, so that the crushed stone can be discharged smoothly, and the above steps are repeated to achieve continuous crushing of the stone.

[0060] Preferably, if the stone to be crushed is large, it is necessary to increase the crushing strength of the stone, therefore, it is necessary to increase the swing angle of the inclined jaw plate 11. At this time, the swing angle of the inclined jaw plate 11 can be adjusted by the crushing control component. At the same time, the first screw 8 can also be driven to rotate, and the first threaded sleeve 9 can be driven to move, so that the rotation center distance between the first threaded sleeve 9 and the first eccentric rod 7 is increased, so that the movement stroke of the inclined support plate 10 and the inclined jaw plate 11 is increased. Under the action of the crushing control component, the swing angle of the inclined jaw plate 11 is increased, thereby increasing the crushing pressure on the stone. The crushing strength can be adjusted by rotating the first screw 8, and the vertical movement stroke of the inclined jaw plate 11 can also be adjusted accordingly to adjust the friction on the stone. Compared with the traditional single-way adjustment, it has the advantages of convenient operation and a large adjustment range.

[0061] The driven crushing mechanism includes a guide rail 25 fixedly mounted on the frame structure 1, a vertical support plate 26 being slidably mounted in the guide rail 25, a movable ring 24 being hinged at the end of the vertical support plate 26, a symmetrically arranged movable rod 30 being slidably mounted on the vertical support plate 26, the movable rod 30 being fixedly connected to the vertical jaw plate 27, an eccentric assembly connected to the first rotating rod 6 being provided on the movable ring 24, wherein the eccentric assembly includes a second eccentric rod 21 movably mounted in the movable ring 24, a symmetrically arranged second screw rod 22 being rotatably mounted on the second eccentric rod 21, a second threaded sleeve 23 threadably matched with the second screw rod 22 being movably mounted on the second screw rod 22, and the second threaded sleeve 23; also includes a second rotating rod 20 rotatably mounted on the frame structure 1, and a belt 19 connected to the first rotating rod 6 is sleeved on the second rotating rod 20.

[0062] Further, in the initial state, the second threaded sleeve 23 is also located at the eccentric position of the second eccentric rod 21. Under the action of the second eccentric rod 21, the movable ring 24 is located at the end of the stroke toward the bottom of the frame structure 1, so that the vertical support plate 26 and the vertical jaw plate 27 are located at the end of the stroke away from the bottom of the frame structure 1. Under the action of the follow-up pushing mechanism, the distance between the vertical jaw plate 27 and the vertical support plate 26 is minimized. At this time, the inclined jaw plate 11 is located at the end of the stroke toward the bottom of the frame structure 1, and the vertical jaw plate 27 and the inclined jaw plate 11 are in a staggered state. In the state, the distance between the two is the largest. When the first rotating rod 6 rotates, it drives the inclined jaw plate 11 to move away from the bottom of the frame structure 1 and swings toward the vertical jaw plate 27. At the same time, the first rotating rod 6 will drive the second rotating rod 20 to rotate through the belt 19, so as to drive the second eccentric rod 21 to move through the second threaded sleeve 23 and the second screw 22. Under the action of the second eccentric rod 21, the vertical support plate 26 is controlled to move along the length direction of the guide rail 25 through the movable ring 24, so as to control the vertical jaw plate 27 to move toward the bottom of the frame structure 1 through the movable rod 30. At this time The vertical jaw plate 27 and the inclined jaw plate 11 move in opposite directions in the vertical direction, and under the action of the first eccentric rod 7 and the second eccentric rod 21, the vertical jaw plate 27 and the inclined jaw plate 11 always move in opposite directions. Therefore, friction forces in two different directions can be provided to the stone. Under the action of the vertical jaw plate 27 and the inclined jaw plate 11, the crushing effect of the stone can be improved, and the friction force on the stone can be increased, thereby preventing the stone from rolling under the action of the crushing pressure, which leads to the problem of increased smoke and dust. If the movement stroke of the vertical jaw plate 27 needs to be adjusted, it can be adjusted by the same method. The second screw 22 adjusts the distance between the second threaded sleeve 23 and the rotation center of the second eccentric rod 21, thereby adjusting the movement stroke of the vertical jaw plate 27. In order to ensure that the stone does not roll, the distance between the second threaded sleeve 23 and the rotation center of the second eccentric rod 21 can be controlled to be always larger than the distance between the first threaded sleeve 9 and the rotation center of the first eccentric rod 7, so that when the stone is crushed, the downward movement stroke of the vertical jaw plate 27 is greater than the upward movement stroke of the inclined jaw plate 11. Under the action of the vertical jaw plate 27, the downward friction force on the stone is greater than the upward friction force, thereby reducing the rolling of the stone.

[0063] Preferably, when the movable rod 30 moves, it will also drive the follow-up pushing mechanism to move, so that when the inclined jaw plate 11 swings toward the vertical jaw plate 27, the vertical jaw plate 27 can also move toward the inclined jaw plate 11. Through the bidirectional action of the vertical jaw plate 27 and the inclined jaw plate 11, it can provide bidirectional crushing pressure to the stone while exerting a kneading force on the stone, so as to further increase the crushing effect of the stone. When the vertical jaw plate 27 and the inclined jaw plate 11 move away from each other, the drop spacing between the two increases rapidly. Compared with the traditional unilateral movement, the vertical jaw plate 27 and the inclined jaw plate 11 can not only improve the crushing efficiency, but also speed up the discharge rate of the stone after crushing, thereby avoiding the problem of excessive overall load of the jaw crusher due to the accumulation of stone in the crushing chamber.

[0064] The follow-up pushing mechanism includes a receiving plate 31 fixedly mounted on the end of the movable rod 30, and the movable rod 30 is sleeved with a second spring 32, and the two ends of the second spring 32 are respectively abutted against the receiving plate 31 and the vertical support plate 26, and a symmetrically arranged limiting wheel 33 is rotatably mounted on the receiving plate 31, and a guide assembly connected to the limiting wheel 33 is provided on the frame structure 1, wherein the guide assembly includes a limiting plate 28 fixedly mounted on the frame structure 1, and a symmetrically arranged inclined block 29 is fixed on the limiting plate 28, and the limiting plate 28 and the inclined block 29 are in abutment with the limiting wheel 33.

[0065] Furthermore, the tilting block 29 is arranged in an inclined shape. In the initial state, the vertical jaw plate 27 is located at the end of the stroke away from the bottom of the frame structure 1, so that the limiting wheel 33 and the tilting block 29 are in a separated state, and the second spring 32 is in a compressed state, so that the limiting wheel 33 abuts against the limiting plate 28, and under the action of the second spring 32, the vertical jaw plate 27 always has a tendency to move toward the vertical support plate 26. When the second eccentric rod 21 rotates, the vertical support plate 26 is driven to move through the movable ring 24, thereby driving the vertical jaw plate 27 to move through the movable rod 30. At the same time, the movable rod 30 will also drive the receiving plate 31 to move, so that the limiting wheel 33 slides on the limiting plate 28. When the limiting wheel 33 moves to abut against the inclined surface of the tilting block 29, the movable rod 30 will move in the direction away from the limiting plate 28 and compress the second spring 3 When the vertical support plate 26 moves to the end of the stroke in the direction away from the bottom of the frame structure 1, the limiting wheel 33 is still in contact with the tilting block 29. At this time, the distance between the vertical jaw plate 27 and the tilting jaw plate 11 is the smallest. When the vertical support plate 26 moves toward the initial position, the limiting wheel 33 will slide the tilting block 29, and the second spring 32 is elastically released, so that the vertical jaw plate 27 moves toward the initial position until the limiting wheel 33 is separated from the tilting block 29 and abuts against the limiting plate 28 again. The above steps are repeated, so that when the vertical support plate 26 moves, the limiting wheel 33 cooperates with the tilting block 29 to control the vertical jaw plate 27 to move in the horizontal direction while moving in the vertical direction, so as to increase the crushing pressure and friction on the stone through the vertical jaw plate 27.

[0066] The crushing and regulating assembly includes a slide groove 201 opened on the horizontal plate 2, a sliding block 13 is slidably installed in the slide groove 201, and a connecting rod 15 hinged to the sliding block 13 is hinged to the inclined support plate 10; it also includes a movable plate 14 fixedly installed on the side wall of the sliding block 13, and a cylinder 12 fixedly connected to the movable plate 14 is fixed on the horizontal plate 2.

[0067] To elaborate, in the initial state, under the action of the cylinder 12, the position of the sliding block 13 is locked by the movable plate 14. When the inclined jaw plate 11 moves toward the bottom of the frame structure 1, the angle between the connecting rod 15 and the cross plate 2 will decrease. Under the action of the connecting rod 15, the inclined support plate 10 is controlled to move toward the direction away from the vertical jaw plate 27. When the inclined jaw plate 11 moves toward the direction away from the bottom of the frame structure 1, the angle between the connecting rod 15 and the cross plate 2 increases. Under the action of the connecting rod 15, the inclined support plate 10 is controlled to move toward the direction away from the vertical jaw plate 27. Therefore, when the inclined jaw plate 11 reciprocates in the vertical direction, the inclined jaw plate 11 is controlled by the connecting rod 15 to reciprocate and swing at a certain angle to crush the stone.

[0068] Preferably, when it is necessary to adjust the crushing size of the stone, the sliding block 13 can be controlled by the cylinder 12 to slide in the slide groove 201, so that the reciprocating swing angle of the inclined support plate 10 can be adjusted by the connecting rod 15. Compared with the traditional single support adjustment of the initial position, the dual adjustment of the cylinder 12 and the first screw 8 can not only achieve the effect of multiple adjustments, but also increase the adjustment range, so that the adjustment range of the stone crushing degree is increased, and under the action of the dual support of the connecting rod 15 and the pull rod 17, the supporting force of the inclined support plate 10 can be increased, thereby avoiding the problem of breaking of the connecting rod 15 or the pull rod 17 due to excessive reaction force on the stone crushing when the connecting rod 15 or the pull rod 17 acts on the inclined support plate 10.

[0069] A jaw crushing method for preventing stone from tumbling during crushing comprises the following steps:

[0070] Step 1: Add stones between the inclined jaw plate 11 and the vertical jaw plate 27;

[0071] Step 2: Under the action of the driving assembly, the active crushing mechanism and the driven crushing mechanism are controlled to move, so as to drive the inclined jaw plate 11 and the vertical jaw plate 27 to perform reciprocating alternating motion in the vertical direction;

[0072] Step 3: When the active crushing mechanism moves, it will also drive the inclined jaw plate 11 to move in the horizontal direction. At the same time, the driven crushing mechanism will control the vertical jaw plate 27 to move in the horizontal direction through the follow-up pushing mechanism, so that the inclined jaw plate 11 and the vertical jaw plate 27 reciprocate in the direction of approaching or moving away from each other to perform a crushing action on the stone;
