Description

Technical Field

[0001] The invention relates to the technical field of crushers, in particular to a jaw crusher used for producing refractory raw materials. Background Art

[0002] Refractory material is a kind of refractory material formed by different raw ores that are crushed by crusher, ground by mill and mixed by sand mixer according to the required proportion. At present, the commonly used traditional jaw crusher is composed of a fixed jaw plate and a movable jaw plate. The movable jaw plate swings up and down to compress and crush the ore between the two.

[0003] However, when the ore fed to a traditional jaw crusher is large, the jaw mouth will be blocked, causing both small and large pieces of ore to be unable to fall; secondly, due to the certain angle between the fixed jaw plate and the movable jaw plate, it takes multiple squeezes to crush the large pieces of ore, and the crushing time is long, resulting in greater wear on the jaw plate and lower crushing efficiency.

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

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the present invention provides a jaw crusher for producing refractory raw materials, wherein a driving rod can drive a reciprocating wire tube to rotate synchronously, so that the reciprocating wire tube drives an L-shaped slider to move back and forth in a slide rail, thereby pushing the ore of the partitioning extrusion piece to both sides, making it convenient for small pieces of ore to fall from the gaps between large pieces of ore, and to be crushed by a fixed jaw plate and a movable jaw plate. At the same time, the driving rod sequentially engages and drives the second bevel gear, the third bevel gear, and the fourth bevel gear to rotate through the first bevel gear, thereby causing the crushing roller to rotate on its own. Combined with the pushing of the partitioning extrusion piece, the large piece of ore can be subjected to crushing forces in multiple directions at the same time, and can be pre-crushed into small pieces of ore, thereby reducing the number of extrusions required for crushing and reducing the wear on the jaw plate, so as to solve the problems raised in the above-mentioned background technology.

[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. The present invention can drive the reciprocating wire tube to rotate synchronously through the driving rod, so that the reciprocating wire tube drives the L-shaped slider to move back and forth in the slide rail, so that the ore of the partitioning extrusion piece is pushed to both sides, which is convenient for small pieces of ore to fall from the gap between large pieces of ore, and is crushed by the fixed jaw plate and the movable jaw plate. At the same time, the driving rod sequentially engages the second bevel gear, the third bevel gear, and the fourth bevel gear through the first bevel gear, so that the crushing roller rotates. With the pushing of the partitioning extrusion piece, the large piece of ore can be subjected to crushing forces in multiple directions at the same time, and can be pre-crushed into small pieces of ore, reducing the number of extrusions required for crushing, reducing the wear on the jaw plate, extending its service life, and improving the crushing efficiency.

[0021] 2. The present invention rotates the eccentric wheel and cooperates with the spring to make the separation and crushing plate vibrate horizontally on the connecting rod, so that the jaw teeth can knock and crush the falling stones, further improving the crushing effect.

[0022] 3. The present invention supplies water to the main pipe and the branch pipe through the water supply mechanism. At this time, the mesh membrane vibrates synchronously with the partition and crushing plate, which can make the water flow turn into mist floating in the air to achieve dust reduction. When the partition and crushing plate is against the surface of the ore and cannot move, the mesh membrane is in a static state. At this time, the mesh membrane sprays a certain amount of water flow, and the water flow falls on the surface of the ore and the fixed jaw plate and the movable jaw plate under the influence of gravity, achieving a cooling effect and reducing the compressive strength of the ore.

[0023] 4. In the present invention, when the pressure detected by the pressure sensor reaches a certain threshold, the magnetic coils in the two groups of limit blocks are energized, causing the two groups of limit blocks to attract each other, thereby making it impossible for the drive rod to drive the reciprocating wire tube to rotate, and making it impossible for the partition extrusion piece to continue to move toward the ore, thereby achieving protection for the partition extrusion piece.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention is further described in detail below based on the accompanying drawings and embodiments.

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

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present 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 are arranged opposite to each other in the jaw crusher body 1, a feed hopper 4 is fixedly installed on the top of the jaw crusher body 1, and a pre-crushing component is arranged between the fixed jaw plate 2 and the movable jaw plate 3;

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

[0042] Specifically, the driving 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 partition extrusion piece 59 to both sides, making it easier for small pieces of ore to fall from the gaps between large pieces of ore and be crushed by the fixed jaw plate 2 and the movable jaw plate 3.

[0043] Among them, large pieces of ore will fall on the top position between the fixed jaw 2 and the movable jaw 3 due to their large volume. The driving rod 55 sequentially engages and drives the second bevel gear 513, the third bevel gear 514, and the fourth bevel gear 516 to rotate through the first bevel gear 511, thereby causing the crushing roller 515 to rotate. Combined with the pushing of the partition extrusion piece 59, the large pieces of ore can be subjected to crushing forces in multiple directions at the same time and pre-crushed into small pieces of ore, thereby improving the crushing efficiency.

[0044] In addition, the crushing roller 515 can generate a downward force on the ore, which can offset the upward force of the fixed jaw 2 and the movable jaw 3 on the ore, thereby reducing the upward splashing of the ore.

[0045] Preferably, the two crushing rollers 515 and the partitioning extrusion piece 59 are located at the same height and are parallel to each other, the partitioning extrusion piece 59 is located between the two crushing rollers 515, and the partitioning extrusion piece 59 and the two crushing rollers 515 are both located at the top between the fixed jaw 2 and the movable jaw 3.

[0046] For further example 2, please refer to Figures 5 and 6 As shown:

[0047] The partitioning extrusion member 59 includes a connecting rod 591 and a partitioning crushing plate 592. The connecting rod 591 is fixedly connected to the L-shaped slider 58. The partitioning crushing plate 592 is symmetrically provided with jaw teeth 593 on both sides facing the crushing roller 515. The interior of the partitioning crushing plate 592 is symmetrically provided with insertion rods 594. The partitioning crushing plate 592 is horizontally slidably connected to the connecting rod 591 through the insertion rods 594, and symmetrical springs 595 are provided between the partitioning crushing plate 592 and the connecting rod 591. A second drive motor 596 is also fixedly installed inside the partitioning crushing plate 592, and an eccentric wheel 597 is fixedly connected to the output end of the second drive motor 596.

[0048] Specifically, the eccentric wheel 597 is driven to rotate by the second driving motor 596, and in combination with the spring 595, the partition crushing plate 592 can vibrate horizontally on the connecting rod 591, and the jaw teeth 593 can knock and crush the fallen stones, further improving the crushing effect.

[0049] For further example 3, please refer to Figures 5 and 6 As shown:

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

[0051] Preferably, the top of the partitioning and crushing plate 592 is a trapezoidal structure, and the water outlets on both sides of the branch pipe 62 are respectively arranged toward the inclined surfaces on both sides of the partitioning and crushing plate 592.

[0052] Preferably, the pore size of the mesh membrane 63 is greater than 0.5 mm, and when the partition and crushing plate 592 is stationary, the water sprayed through the mesh membrane 63 is in a stream.

[0053] Specifically, due to the crushing performed by the jaw teeth 593, the crushing roller 515, the fixed jaw plate 2 and the movable jaw plate 3, a large amount of dust will be generated. The water supply mechanism supplies water to the main pipe 61 and the branch pipe 62. At this time, the mesh membrane 63 vibrates synchronously with the partition crushing plate 592, so that the water flow becomes mist floating in the air, thereby achieving the dust reduction effect. When the partition crushing plate 592 is 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 a certain amount of water flow, and the water flow falls on the surface of the ore and the fixed jaw plate 2 and the movable jaw plate 3 under the influence of gravity, thereby achieving a cooling effect and reducing the compressive strength of the ore.

[0054] For further example 4, please refer to Figure 5 and Figure 7 As shown:

[0055] A protection component is arranged between the driving rod 55 and the reciprocating wire tube 57, and the protection component includes two groups of limit blocks 71. Magnetic coils 72 are fixedly installed inside the two groups of limit blocks 71. A limit groove 73 is opened on the driving rod 55. One group of limit blocks 71 is fixedly installed inside the reciprocating wire tube 57, and the other group of limit blocks 71 can slide along the inside of the reciprocating wire tube 57 and can be adapted to be clamped with the limit groove 73. A pressure sensor 74 is arranged 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 driving rod 55 and the reciprocating wire tube 57 .

[0058] Specifically, the pressure sensor 74 can detect the extrusion force exerted on the connecting rod 591. In order to prevent the partition extrusion member 59 from being damaged by the extrusion of 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 groups of limit blocks 71, so that the two groups of limit blocks 71 attract each other, thereby separating the movable limit blocks 71 from the limit grooves 73, and the driving rod 55 cannot drive the reciprocating wire tube 57 to rotate, so that the partition extrusion member 59 remains stationary and cannot continue to move toward the ore, thereby achieving braking protection.

[0059] Everything in the above example works like this:

[0060] When in use, the first drive motor 53 is started, so that the driving gear 54 meshes with the driven gear 56 to drive the driving rod 55 to rotate, and the driving rod 55 drives 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, and the partition extrusion piece 59 is used to push the ore to both sides. At the same time, the driving rod 55 meshes with the second bevel gear 513, the third bevel gear 514, and the fourth bevel gear 516 through the first bevel gear 511 to rotate in sequence, so that the crushing roller 515 rotates, and the large pieces of ore can be pre-crushed into small pieces of ore by the pushing of the partition extrusion piece 59.

[0061] Furthermore, the eccentric wheel 597 is driven to rotate by the second driving motor 596, and in combination with the spring 595, the partition crushing plate 592 can vibrate horizontally on the connecting rod 591, and the jaw teeth 593 can knock and crush the fallen stones.

[0062] When in use, the water supply mechanism supplies water to the main pipe 61 and the branch pipe 62. At this time, the mesh membrane 63 vibrates synchronously with the partition and crushing plate 592, so that the water flow becomes mist floating in the air, thereby achieving dust reduction. When the partition and crushing plate 592 is 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 a certain amount of water flow, and the water flow falls on the surface of the ore and the fixed jaw plate 2 and the movable jaw plate 3 under the influence of gravity, thereby achieving a cooling effect and reducing 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 groups of limit blocks 71, so that the two groups of limit blocks 71 attract each other, thereby separating the movable limit blocks 71 from the limit grooves 73, and the driving rod 55 cannot drive the reciprocating wire tube 57 to rotate, so that the partition extrusion member 59 remains stationary and cannot continue to move toward the ore, thereby protecting the partition extrusion member 59.
