Description

Technical Field

[0001] This invention relates to the field of crusher technology, specifically to a jaw crusher for producing refractory raw materials. Background Technology

[0002] Refractory materials are made by crushing different raw materials in a crusher, grinding them in a mill, and mixing them in a sand mixer according to the required proportions. Currently, the commonly used traditional jaw crusher consists of a fixed jaw plate and a movable jaw plate. The ore is compressed and crushed between the two plates by the up and down swinging of the movable jaw plate.

[0003] However, traditional jaw crushers can cause blockages in the jaw opening when the ore being fed is large, preventing both small and large pieces of ore from falling. Secondly, due to the angle between the fixed and movable jaw plates, large pieces of ore need to be crushed through multiple compressions, resulting in a longer crushing time, greater wear on the jaw plates, and lower crushing efficiency.

[0004] Therefore, a jaw crusher for producing refractory raw materials was proposed to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a jaw crusher for producing refractory raw materials. A drive rod drives a reciprocating wire tube to rotate synchronously, causing the L-shaped slider to reciprocate within a slide rail. This pushes the ore to both sides through the separating extrusion components, facilitating the falling of smaller ore pieces from the gaps between larger ore pieces. These smaller pieces are then crushed by the fixed and movable jaw plates. Simultaneously, the drive rod, through the sequential meshing of a first bevel gear with a second, third, and fourth bevel gear, rotates the crushing roller. Combined with the pushing action of the separating extrusion components, large ore pieces are subjected to crushing forces from multiple directions simultaneously, pre-crushing them into smaller pieces. This reduces the number of crushing cycles required and decreases wear on the jaw plates, thus solving the problems mentioned in the background art.

Symmetrical springs are arranged between the separating crushing plate and the connecting rod. A second drive motor is also fixedly installed inside the separating crushing plate. An eccentric wheel is fixedly connected to the output end of the second drive motor.

[0012] Preferably, a dust suppression component is provided on the top of the separating crushing plate.

[0017] Preferably, the limiting block, magnetic coil, and limiting groove are all arranged along the diameter direction of the drive rod and the reciprocating wire tube.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a jaw crusher for producing refractory raw materials, which has the following beneficial effects:

[0020] 1. This invention uses a drive rod to drive a reciprocating wire tube to rotate synchronously, causing the L-shaped slider of the reciprocating wire tube to move back and forth within the slide rail. This pushes the ore to both sides through the separating extrusion piece, facilitating the falling of smaller pieces of ore through the gaps between larger pieces. The smaller pieces are then crushed by the fixed and movable jaw plates. Simultaneously, the drive rod, through the sequential meshing of the first bevel gear, drives the second, third, and fourth bevel gears to rotate, causing the crushing roller to rotate. Combined with the pushing action of the separating extrusion piece, large pieces of ore can be subjected to crushing forces from multiple directions simultaneously, pre-crushing them into smaller pieces. This reduces the number of extrusion cycles required for crushing, decreases wear on the jaw plates, extends their service life, and improves crushing efficiency.

[0021] 2. This invention uses the rotation of an eccentric wheel and a spring to make the separating crushing plate vibrate horizontally on the connecting rod, so that the jaw teeth can knock and crush the falling stone, further improving the crushing effect.

[0022] 3. In this invention, water is supplied to the main pipe and branch pipes through a water supply mechanism. At this time, the perforated membrane vibrates synchronously with the separating and crushing plate, which can turn the water flow into mist and float in the air to achieve the dust suppression effect. When the separating and crushing plate is pressed against the surface of the ore and cannot move, the perforated membrane is in a stationary state. At this time, the perforated membrane sprays out a certain amount of water flow. The water flow is affected by gravity and falls on the surface of the ore and the fixed jaw plate and the movable jaw plate to achieve the cooling effect and reduce the compressive strength of the ore.

[0023] 4. When the pressure detected by the pressure sensor reaches a certain threshold, the magnetic coils in the two sets of limit blocks are energized, causing the two sets of limit blocks to attract each other, thereby preventing the drive rod from driving the reciprocating wire tube to rotate and preventing the separating extrusion piece from continuing to move toward the ore, thus achieving protection of the separating extrusion piece.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0039] Example 1, please refer to Figures 1 to 4 As shown:

[0040] To address the problems mentioned in the technical solutions, this application provides a jaw crusher for producing refractory raw materials, including a jaw crusher body 1, a fixed jaw plate 2 and a movable jaw plate 3 arranged facing each other inside the jaw crusher body 1, a feed hopper 4 fixedly installed on the top of the jaw crusher body 1, and a pre-crushing component arranged between the fixed jaw plate 2 and the movable jaw plate 3.

[0041] The pre-crushing assembly includes a baffle 51, with a slide rail 52 in the middle. A first drive motor 53 is fixedly installed on both the front and rear sides of the feed hopper 4. A drive gear 54 is fixedly connected to the output end of the first drive motor 53. A drive rod 55 is rotatably connected inside the baffle 51. Driven gears 56 are fixedly sleeved on both sides of the drive rod 55 along its length. The drive gear 54 meshes with the driven gear 56. A reciprocating wire tube 57 is sleeved in the middle of the driven gear 56. The reciprocating wire tube 57 is located inside the slide rail 52, and an L-shaped slider 58 is connected to the outer surface of the reciprocating wire tube 57. The L-shaped slider 58 slides along the inner surface of the slide rail 52. A separating extrusion element 59 is provided on the L-shaped slider 58. The jaw crusher body 1... The roller cover box 510 is symmetrically arranged on the front and rear sides. The two ends of the drive rod 55 are fixedly connected to the first bevel gear 511. The drive shaft 512 is rotatably connected to the roller cover box 510. The top end of the drive shaft 512 is fixedly connected to the second bevel gear 513, and the bottom end of the drive shaft 512 is fixedly connected to the third bevel gear 514. The crushing roller 515 is rotatably connected inside the roller cover box 510, and one end of the crushing roller 515 is fixedly connected to the fourth bevel gear 516. The first bevel gear 511 meshes with the second bevel gear 513, and the third bevel gear 514 meshes with the fourth bevel gear 516. The roller cover box 510 is provided with a partition 517, and the partition 517 is located between the crushing roller 515 and the fourth bevel gear 516.

[0042] Specifically, the drive rod 55 can drive the reciprocating wire tube 57 to rotate synchronously, so that the reciprocating wire tube 57 drives the L-shaped slider 58 to move back and forth in the slide rail 52, thereby pushing the ore of the separating extrusion piece 59 to both sides, so that small pieces of ore can fall from the gap of large pieces of ore and be crushed by the fixed jaw plate 2 and the movable jaw plate 3.

[0043] Large pieces of ore, due to their large size, will fall at the top position between the fixed jaw plate 2 and the movable jaw plate 3. The drive rod 55 will drive the second bevel gear 513, the third bevel gear 514, and the fourth bevel gear 516 to rotate through the first bevel gear 511 in sequence, thereby causing the crushing roller 515 to rotate. Combined with the pushing of the separating extrusion piece 59, the large pieces of ore can be subjected to crushing forces from multiple directions at the same time and be pre-crushed into smaller pieces of ore, thereby improving crushing efficiency.

[0044] Furthermore, the crushing roller 515 can generate a downward force on the ore, which cancels out the component force of the fixed jaw plate 2 and the movable jaw plate 3 on the upward force on the ore, thereby reducing the upward splashing of ore.

[0045] Preferably, the two crushing rollers 515 and the separating extruder 59 are located at the same height and parallel to each other, with the separating extruder 59 located between the two crushing rollers 515. Both the separating extruder 59 and the two crushing rollers 515 are located at the top between the fixed jaw plate 2 and the movable jaw plate 3.

[0046] For a further embodiment two, please refer to Figures 5 to 6 As shown:

[0047] The separating extrusion component 59 includes a connecting rod 591 and a separating crushing plate 592. The connecting rod 591 is fixedly connected to the L-shaped slider 58. The separating crushing plate 592 has symmetrically arranged jaw teeth 593 on both sides facing the crushing roller 515. The separating crushing plate 592 has symmetrically arranged insert rods 594 inside. The separating crushing plate 592 is horizontally slidably connected to the connecting rod 591 through the insert rods 594. Symmetrical springs 595 are arranged between the separating crushing plate 592 and the connecting rod 591. A second drive motor 596 is also fixedly installed inside the separating crushing plate 592. An eccentric wheel 597 is fixedly connected to the output end of the second drive motor 596.

[0048] Specifically, the second drive motor 596 drives the eccentric wheel 597 to rotate, and with the spring 595, the separating crushing plate 592 can vibrate horizontally on the connecting rod 591, which allows the jaw teeth 593 to knock and crush the falling stone, further improving the crushing effect.

[0049] For a further embodiment three, please refer to Figures 5 to 6 As shown:

[0050] A dust suppression component is provided on the top of the separation and crushing plate 592. The dust suppression component includes a main pipe 61, and branch pipes 62 are uniformly connected along the length of the main pipe 61. A mesh membrane 63 is fixedly installed at the outlet of the branch pipe 62, and the inlet of the main pipe 61 is connected to the water supply mechanism.

[0051] Preferably, the top of the dividing and crushing plate 592 is trapezoidal, and the outlets on both sides of the branch pipe 62 are respectively set towards the two inclined surfaces of the dividing and crushing plate 592.

[0052] Preferably, the perforated membrane 63 has a pore size greater than 0.5 mm, so that when the separating and breaking plate 592 is stationary, the water sprayed through the perforated membrane 63 is in a flowing state.

[0053] Specifically, since the jaw teeth 593, crushing roller 515, fixed jaw plate 2, and movable jaw plate 3 are used in combination for crushing, a large amount of dust is generated. Water is supplied to the main pipe 61 and branch pipe 62 by the water supply mechanism. At this time, the mesh membrane 63 vibrates synchronously with the separating crushing plate 592, so that the water flow turns into mist and floats in the air, achieving the dust suppression effect. When the separating crushing plate 592 is pressed against the surface of the ore and cannot move, the mesh membrane 63 is in a stationary state. At this time, the mesh membrane 63 sprays out a certain amount of water flow. The water flow is affected by gravity and falls on the surface of the ore and the fixed jaw plate 2 and movable jaw plate 3, achieving the cooling effect and reducing the compressive strength of the ore.

[0054] For a further embodiment four, please refer to Figure 5 and Figure 7 As shown:

[0055] A protective assembly is provided between the drive rod 55 and the reciprocating wire tube 57. The protective assembly includes two sets of limiting blocks 71. A magnetic coil 72 is fixedly installed inside each of the two sets of limiting blocks 71. A limiting groove 73 is opened on the drive rod 55. One set of limiting blocks 71 is fixedly installed inside the reciprocating wire tube 57. The other set of limiting blocks 71 can slide along the inside of the reciprocating wire tube 57 and can be adapted and snapped into the limiting groove 73. A pressure sensor 74 is provided between the connecting rod 591 and the L-shaped slider 58.

[0056] Preferably, the pressure sensor 74 is electrically connected to the control terminal, and the magnetic coil 72 is electrically connected to the control terminal.

[0057] Preferably, the limiting block 71, the magnetic coil 72, and the limiting groove 73 are all arranged along the diameter direction of the drive rod 55 and the reciprocating wire tube 57.

[0058] Specifically, the pressure sensor 74 can detect the compressive force on the connecting rod 591. In order to prevent the separating extrusion piece 59 from being damaged by the ore, when the pressure detected by the pressure sensor 74 reaches a certain threshold, the control terminal can energize the magnetic coils 72 in the two sets of limit blocks 71, so that the two sets of limit blocks 71 attract each other, thereby separating the movable limit block 71 from the limit groove 73. The drive rod 55 cannot drive the reciprocating wire tube 57 to rotate, so that the separating extrusion piece 59 remains stationary and cannot continue to move toward the ore, thereby achieving braking protection.

[0059] The working principle of all the content in the above embodiments is as follows:

[0060] In use, the first drive motor 53 is started, causing the drive gear 54 to mesh with the driven gear 56 to drive the drive rod 55 to rotate. The drive rod 55 drives the reciprocating wire tube 57 to rotate synchronously, causing the reciprocating wire tube 57 to drive the L-shaped slider 58 to move back and forth in the slide rail 52. The separating extrusion member 59 pushes the ore to both sides. At the same time, the drive rod 55, through the first bevel gear 511, sequentially meshes with the second bevel gear 513, the third bevel gear 514, and the fourth bevel gear 516 to rotate, thereby causing the crushing roller 515 to rotate. Combined with the pushing of the separating extrusion member 59, large pieces of ore can be pre-crushed into small pieces of ore.

[0061] Furthermore, by driving the eccentric wheel 597 to rotate via the second drive motor 596, and in conjunction with the spring 595, the separating crushing plate 592 can vibrate horizontally on the connecting rod 591, which allows the jaw teeth 593 to crush the falling stones by impact.

[0062] During use, water is supplied to the main pipe 61 and branch pipe 62 by the water supply mechanism. At this time, the perforated membrane 63 vibrates synchronously with the separating crushing plate 592, causing the water flow to turn into mist and float in the air to achieve dust suppression. When the separating crushing plate 592 is pressed against the surface of the ore and cannot move, the perforated membrane 63 is in a stationary state. At this time, the perforated membrane 63 sprays out a certain amount of water flow. The water flow is affected by gravity and falls on the surface of the ore and the fixed jaw plate 2 and the movable jaw plate 3 to achieve cooling effect and reduce the compressive strength of the ore.

[0063] When the pressure detected by the pressure sensor 74 reaches a certain threshold, the control terminal can energize the magnetic coils 72 in the two sets of limit blocks 71, causing the two sets of limit blocks 71 to attract each other, thereby separating the movable limit block 71 from the limit groove 73. The drive rod 55 cannot drive the reciprocating wire tube 57 to rotate, keeping the separating extrusion piece 59 stationary and unable to continue moving towards the ore, thus protecting the separating extrusion piece 59.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
