Description

Technical Field

[0001] This invention relates to the field of stone crushing technology, specifically a jaw crusher and method for preventing stone from tumbling during crushing. Background Technology

[0002] Jaw crushers are mainly used for medium and fine crushing of ores, coal, or other medium-strength materials. Their crushing method is a reciprocating compression type, relying on two wear-resistant jaw plates to crush the material.

[0003] Its working principle is that the movable jaw plate makes a periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing chamber and the finished product is discharged from the bottom; when approaching, the material between the two jaw plates is crushed by compression, bending and splitting.

[0004] Existing crushers typically have only one moving jaw plate, which results in low efficiency. If two jaw plates are driven to move together and interact, the eccentricity cannot be changed when the two jaw plates are driven to move by the eccentric rod. The contact area between the two jaw plates and the stone remains unchanged during a single alternating up and down movement. During crushing, the jaw plates may provide a certain reaction force to the stone, causing the stone to roll upwards, resulting in poor crushing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a jaw crusher and method for preventing crushed stone from tumbling, so as to solve the problems mentioned in the background art.

[0016] It also includes an inclined support plate sleeved on the first eccentric rod, the inclined support plate being fixedly connected to the inclined jaw plate, and a tie rod assembly connected to the inclined support plate being provided on the cross plate.

[0017] As a further embodiment of the present invention: the pull rod assembly includes a rotating sleeve rotatably mounted on the horizontal plate, a limit ring fixed at the end of the rotating sleeve, a pull rod slidably mounted inside the rotating sleeve and hinged to the inclined support plate, and a first spring sleeved on the pull rod and abutting against the limit ring.

[0018] As a further embodiment of the present invention: the driven crushing mechanism includes a guide rail fixedly installed on the frame structure, a vertical support plate slidably installed in the guide rail, a movable ring hinged to the end of the vertical support plate, movable rods symmetrically arranged slidably installed on the vertical support plate, the movable rods being fixedly connected to the vertical jaw plate, and an eccentric component connected to the first rotating rod being provided on the movable ring.

[0019] As a further embodiment of the present invention: the eccentric assembly includes a second eccentric rod movably installed within the movable ring, a second lead screw rotatably mounted on the second eccentric rod and symmetrically arranged, and a second threaded sleeve movably mounted on the second lead screw and threadedly engaged with the second lead screw, the second threaded sleeve;

[0020] It also includes a second rotating rod rotatably mounted on the frame structure, and a belt connected to the first rotating rod is sleeved on the second rotating rod.

[0021] As a further embodiment of the present invention: the follow-up pushing mechanism includes a receiving plate fixedly installed at the end of the movable rod, a second spring is sleeved on the movable rod, the two ends of the second spring abut against the receiving plate and the vertical support plate respectively, a symmetrically arranged limiting wheel is rotatably installed on the receiving plate, and a guide component connected to the limiting wheel is provided on the frame structure.

[0022] As a further embodiment of the present invention: the guiding component includes a limiting plate fixedly installed on the frame structure, and inclined blocks arranged symmetrically are fixed on the limiting plate. The limiting plate and the inclined blocks abut against the limiting wheel.

[0023] As a further embodiment of the present invention: the crushing control component includes a groove formed on the horizontal plate, a sliding block is slidably installed in the groove, and a connecting rod hinged to the sliding block and hinged to the inclined support plate;

[0024] It also includes a movable plate fixedly installed on the side wall of the sliding block, and a cylinder fixedly connected to the movable plate is fixed on the horizontal plate.

[0025] A jaw crushing method for preventing crushed stone from tumbling includes 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 drive component, control the movement of the active crushing mechanism and the driven crushing mechanism to drive the inclined jaw plate and the vertical jaw plate to reciprocate alternately 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 reciprocate in the direction of moving closer or further away from each other to perform crushing action on the stone.

[0029] Step 4: The movement of the active crushing mechanism can also be controlled by the crushing control component to adjust the travel of the inclined jaw plate.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows: The present application can provide a dual 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 drive 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 vertically and reciprocate horizontally by the crushing control component. At the same time, when the driven crushing mechanism moves, the vertical jaw plate is controlled to move vertically and reciprocate horizontally by the follow-up pushing mechanism. The vertical jaw plate and the inclined jaw plate move alternately in the vertical direction and move closer or further apart in the horizontal direction, thereby achieving a dual 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 also be adjusted according to the crushing condition of the stone to change the dual friction force applied to the stone, ensuring that the stone always has a downward force during the crushing process, so as to ensure that the stone does not roll and reduce the generation of dust.

[0031] After the stone is crushed and discharged, compared with the traditional single-sided movement, the vertical jaw plate and the inclined jaw plate can improve the crushing efficiency and accelerate the discharge rate of the crushed stone, thereby avoiding the problem of excessive overall load on the device due to the accumulation of stone in the crushing chamber.

[0032] By adjusting both the cylinder and the first lead screw, multiple adjustments can be made, and the adjustment range can be increased, thus increasing the range of adjustment for the degree of stone crushing. Furthermore, under the dual support of the connecting rod and the tie rod, the supporting force on the inclined support plate can be increased, thereby avoiding the problem of the connecting rod or tie rod breaking due to excessive reaction force on the stone crushing when the connecting rod or tie rod acts on the inclined support plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figures 1 to 11 In this embodiment of the invention, a jaw crusher for preventing crushed stone from tumbling includes:

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

[0049] Also includes:

[0050] A drive assembly is mounted on the frame structure 1. An active crushing mechanism connected to the drive assembly is mounted on the cross plate 2. An inclined jaw plate 11 is connected to the active crushing mechanism.

[0051] A driven crushing mechanism is mounted on the frame structure 1 and connected to the drive assembly. A vertical jaw plate 27 is connected to the driven crushing mechanism. The drive 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 reciprocate and alternate in the vertical direction.

[0052] A follower pushing mechanism is provided on the frame structure 1 and connected to the driven crushing mechanism. The follower 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 control component is disposed on the horizontal plate 2 and connected to the active crushing mechanism. The crushing control 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 to form a crushing chamber. When crushing stone, the stone can be added into the crushing chamber, driving the component to work and driving the active crushing mechanism and the driven crushing mechanism 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. When the inclined jaw plate 11 and the vertical jaw plate 27 move in the horizontal direction, they will move towards each other or away from each other to increase the crushing intensity of the stone. When the inclined jaw plate 11 and the vertical jaw plate 27 move in the vertical direction, they reciprocate and alternately to increase the friction of the stone and ensure that the stone will not roll over during crushing, thereby reducing the generation of dust. If it is necessary to adjust the crushing size of the stone, the movement stroke of the inclined jaw plate 11 is adjusted by the active crushing mechanism under the action of the crushing control component to adjust the crushing size of the stone.

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

[0056] In detail, when it is necessary to crush the stone, the movement of the active crushing mechanism needs to be controlled. 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 drive pulley is mounted on the output shaft of motor 3, and a transmission belt 4 is fitted onto the drive pulley and the driven pulley 5. When crushing stone, the required crushing pressure is relatively large, so the load on motor 3 is relatively large. However, the rotation radius of driven pulley 5 is much larger than that of drive pulley. Therefore, under the action of drive pulley, the torque and force of the transmission system can be increased while reducing the power of motor 3, thereby improving transmission efficiency, reducing costs, extending equipment service life, and enhancing equipment reliability. This allows for driving a large load with a small torque, ensuring that the motor 3 will not be damaged due to excessive load when crushing stone.

[0058] The active crushing mechanism includes a first eccentric rod 7 mounted on the frame structure 1, a first lead screw 8 symmetrically arranged and rotatably mounted on the first eccentric rod 7, a first threaded sleeve 9 threadedly engaged with the first lead screw 8 and movably mounted on the first lead screw 8, and the first threaded sleeve 9 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 fixedly connected to the inclined jaw plate 11, and a pull rod assembly connected to the inclined support plate 10 provided on the horizontal plate 2, wherein the pull rod assembly includes a rotating sleeve 16 rotatably mounted on the horizontal plate 2, a limit ring 1601 fixed at the end of the rotating sleeve 16, a pull rod 17 hinged to the inclined support plate 10 and slidably mounted inside the rotating sleeve 16, and a first spring 18 abutting against the limit ring 1601 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 its stroke towards 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 its stroke towards 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 threaded sleeve 9 and the first screw 8 drive the first eccentric rod 7 to rotate eccentrically, thereby driving the inclined support plate 10 to move, causing the inclined jaw plate 11 to move. When the inclined jaw plate 11 moves towards 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 swings towards the vertical jaw plate 27, so as to pass through... The stone is crushed by the cooperation of the inclined jaw plate 11 and the vertical jaw plate 27. The inclined support plate 10 also drives the pull rod 17 to move and drives 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 their stroke towards 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 the 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 towards the initial position. The first spring 18 is released elastically, 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 increases, so that the crushed stone can be discharged smoothly. 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 intensity 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 lead screw 8 can 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 increases, thereby increasing the stroke of the inclined support plate 10 and the inclined jaw plate 11. 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 intensity can be adjusted by rotating the first lead screw 8, and the stroke of the inclined jaw plate 11 in the vertical direction can also be adjusted accordingly to adjust the friction force on the stone. Compared with the traditional method of only one-way adjustment, it has the advantages of convenient operation and large adjustment range.

[0061] The driven crushing mechanism includes a guide rail 25 fixedly installed on the frame structure 1, a vertical support plate 26 slidably installed inside the guide rail 25, a movable ring 24 hinged to the end of the vertical support plate 26, and symmetrically arranged movable rods 30 slidably installed on the vertical support plate 26. The movable rods 30 are fixedly connected to the vertical jaw plate 27. An eccentric assembly connected to the first rotating rod 6 is provided on the movable ring 24. The eccentric assembly includes a second eccentric rod 21 movably installed inside the movable ring 24, a second lead screw 22 symmetrically arranged rotatably installed on the second eccentric rod 21, and a second threaded sleeve 23 threadedly engaged with the second lead screw 22 movably installed on the second lead screw 22. The second threaded sleeve 23 also includes a second rotating rod 20 rotatably installed 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] Furthermore, 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 its stroke towards 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 their 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 its stroke towards the bottom of the frame structure 1, and the vertical jaw plate 27 and the inclined jaw plate 11 are staggered. In this state, the distance between the two is at its maximum. 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, while simultaneously swaying towards the vertical jaw plate 27. At the same time, the first rotating rod 6 will drive the second rotating rod 20 to rotate via the belt 19, which in turn drives the second eccentric rod 21 to move via the second threaded sleeve 23 and the second lead screw 22. Under the action of the second eccentric rod 21, the vertical support plate 26 is controlled to move along the length of the guide rail 25 via the movable ring 24, and the vertical jaw plate 27 is controlled to move towards the bottom of the frame structure 1 via the movable rod 30. The vertical jaw plate 27 and the inclined jaw plate 11 move in opposite directions in the vertical direction. Under the action of the first eccentric rod 7 and the second eccentric rod 21, the movement directions of the vertical jaw plate 27 and the inclined jaw plate 11 are always kept opposite. Therefore, frictional forces can be provided to the stone in two different directions. Under the action of the vertical jaw plate 27 and the inclined jaw plate 11, both the crushing effect on the stone and the frictional force on the stone can be improved, thereby preventing the stone from rolling under crushing pressure and causing an increase in dust. Similarly, if it is necessary to adjust the stroke of the vertical jaw plate 27, it can be adjusted by... The second lead screw 22 adjusts the distance between the rotation center of the second threaded sleeve 23 and the second eccentric rod 21, thereby adjusting the movement stroke of the vertical jaw plate 27. 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 always be greater than the distance between the first threaded sleeve 9 and the rotation center of the first eccentric rod 7. This ensures 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 stone experiences a greater downward frictional force than an upward frictional force, thereby reducing the rolling of the stone.

[0063] Preferably, when the movable rod 30 moves, it also drives the follow-up pushing mechanism to move, so that when the inclined jaw plate 11 swings towards the vertical jaw plate 27, the vertical jaw plate 27 can also move towards the inclined jaw plate 11. Through the bidirectional action of the vertical jaw plate 27 and the inclined jaw plate 11, the bidirectional crushing pressure of the stone can be provided at the same time, and the kneading force of the stone can be applied 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 material drop distance between them increases rapidly. Compared with the traditional unilateral movement, the vertical jaw plate 27 and the inclined jaw plate 11 can improve the crushing efficiency and accelerate the discharge rate of the crushed stone, 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 installed at the end of the movable rod 30. A second spring 32 is sleeved on the movable rod 30. The two ends of the second spring 32 abut against the receiving plate 31 and the vertical support plate 26, respectively. A symmetrically arranged limiting wheel 33 is rotatably installed on the receiving plate 31. A guide assembly connected to the limiting wheel 33 is provided on the frame structure 1. The guide assembly includes a limiting plate 28 fixedly installed on the frame structure 1. A symmetrically arranged inclined block 29 is fixed on the limiting plate 28. The limiting plate 28 and the inclined block 29 abut against the limiting wheel 33.

[0065] Furthermore, the tilting block 29 is tilted. In the initial state, the vertical jaw plate 27 is located at the end of its stroke away from the bottom of the frame structure 1, causing the limiting wheel 33 to be separated from the tilting block 29. The second spring 32 is compressed, causing the limiting wheel 33 to abut against the limiting plate 28. Under the action of the second spring 32, the vertical jaw plate 27 always tends to move towards the vertical support plate 26. When the second eccentric rod 21 rotates, it drives the vertical support plate 26 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 also drives the receiving plate 31 to move, causing the limiting wheel 33 to slide on the limiting plate 28. When the limiting wheel 33 moves to abut against the tilting surface of the tilting block 29, the movable rod 30 will move away from the limiting plate 28 and compress the second spring 32. 2. The movable rod 30 will also drive the vertical jaw plate 27 to move away from the vertical support plate 26. When the vertical support plate 26 moves to the end of its stroke 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 towards the initial position, the limiting wheel 33 will slide the tilting block 29, and the second spring 32 will be released elastically, so that the vertical jaw plate 27 moves towards the initial position until the limiting wheel 33 disengages 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 and the tilting block 29 cooperate to control the vertical jaw plate 27 to move in the vertical direction while moving in the horizontal direction, so as to increase the crushing pressure and friction of the stone through the vertical jaw plate 27.

[0066] The crushing control component includes a groove 201 formed on the horizontal plate 2, a sliding block 13 slidably installed in the groove 201, and a connecting rod 15 hinged to the sliding block 13 and 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] In the initial state, under the action of cylinder 12, the position of sliding block 13 is locked by movable plate 14. When inclined jaw plate 11 moves toward the bottom of frame structure 1, the angle between connecting rod 15 and horizontal plate 2 will decrease. Under the action of connecting rod 15, inclined support plate 10 is controlled to move away from vertical jaw plate 27. When inclined jaw plate 11 moves away from the bottom of frame structure 1, the angle between connecting rod 15 and horizontal plate 2 increases. Under the action of connecting rod 15, inclined support plate 10 is controlled to move away from vertical jaw plate 27. Therefore, when inclined jaw plate 11 reciprocates in the vertical direction, connecting rod 15 controls inclined jaw plate 11 to swing back and forth at a certain angle to crush 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 groove 201, thereby adjusting the angle of the reciprocating swing of the inclined support plate 10 through 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 lead screw 8 can achieve multiple adjustment effects and increase the adjustment range, thereby increasing the adjustment range of the crushing degree of the stone. Under the dual support of the connecting rod 15 and the tie rod 17, the supporting force on the inclined support plate 10 can be increased, thereby avoiding the problem of the connecting rod 15 or the tie rod 17 breaking due to excessive reaction force on the crushing of the stone when the connecting rod 15 or the tie rod 17 acts on the inclined support plate 10.

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

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

[0071] Step 2: Under the action of the drive component, control the movement of the active crushing mechanism and the driven crushing mechanism to drive the inclined jaw plate 11 and the vertical jaw plate 27 to reciprocate alternately 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 moving closer or further away from each other, so as to perform crushing action on the stone.

[0073] Step 4: The movement of the active crushing mechanism can also be controlled by the crushing control component to adjust the stroke of the inclined jaw plate 11.

[0074] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
