Description

Technical Field

[0001] The invention relates to the technical field of spodumene processing, in particular to a jaw coarse crusher for fine crushing of spodumene. Background Art

[0002] In the crushing production line, especially for the crushing of large pieces of materials, jaw crusher is usually used as coarse crushing equipment, that is, the crushing equipment of the first process, so it is also called jaw coarse crusher. It is responsible for crushing large pieces of materials into medium particle size for subsequent fine crushing and processing. The hardness and uneven particle size distribution of spodumene may make it difficult for some materials to be effectively crushed, thus clogging in the crushing chamber.

[0003] Viscosity: If spodumene contains high moisture or sticky substances, it is easy to stick to the inside of the equipment during the crushing process, causing blockage.

[0004] The jaw crusher crushes materials through the cyclic motion between the movable jaw and the fixed jaw. If the material falls too slowly, a large amount of material will be blocked in the crushing chamber, causing the feed port to be blocked. At this time, some tools are needed to clean it before it can continue to run. Using tools to clean it is inefficient and there are certain safety risks, which is not conducive to the processing and production efficiency of spodumene ore. Summary of the invention

The outer surface of the slider is also fixedly connected to a gear fixing plate, and the outer surface of the gear fixing plate is rotatably connected to a gear shaft.

[0011] Preferably, the lower end of the rotating shaft is fixedly connected with a manganese steel tip, and a movable groove is provided on the outer surface of the manganese steel tip, in which a movable shaft is rotatably connected, and an arc-shaped hook plate is fixedly sleeved on the outer surface of the movable shaft, and both sides of the lower edge of the arc-shaped hook plate are chamfered, and a torsion spring for applying an outward opening force to the arc-shaped hook plate is provided between the arc-shaped hook plate and the inner wall of the movable shaft.

[0012] Preferably, the knocking and oscillation assembly also includes two slide groove rails, both of which are fixedly connected to the outer surface of the mounting plate, both of which are slidably connected to sliding rods, and both of which are rotatably connected to rollers at opposite ends. A worm shaft is fixedly sleeved on the outer surface of the output shaft of the motor, and an S-shaped oscillation cam is fixedly sleeved on the outer surface of the worm shaft, and the outer contour of the S-shaped oscillation cam is adapted to the two rollers.

[0013] Preferably, the two L-shaped plates are respectively fixedly connected to the opposite ends of the two sliding rods, and the ends of the two L-shaped plates away from the sliding rods are fixedly connected with impact blocks for knocking the feed port, and tension springs are fixedly connected between the two L-shaped plates and the mounting plate.

[0014] Preferably, a self-locking reduction transmission assembly is provided on the mounting plate, and the self-locking reduction transmission assembly is used for transmission, and the self-locking reduction transmission assembly includes two fixed shaft seats.

[0015] Preferably, the two fixed shaft seats are rotatably connected to the outer surface of the worm shaft, the outer surface of the worm shaft is fixedly sleeved with a worm, the outer surface of a sprocket shaft in the anti-blocking motion component is fixedly sleeved with a worm wheel, and the worm wheel is meshingly connected to the worm.

[0016] Compared with the prior art, the present invention provides a jaw coarse crusher for fine crushing of spodumene, which has the following beneficial effects: The jaw crusher for fine crushing of spodumene also swings back and forth when clearing the spodumene ore blocked in the jaw crusher body obliquely upward through the swinging material cleaning component, which enables the reciprocating arc-shaped hook plate to pull the spodumene ore blocked in the jaw crusher body to both sides and move it obliquely upward at the same time, so that the blocked spodumene ore can be effectively cleaned, avoiding the safety risks and low work efficiency brought by manual cleaning in the traditional method, and realizing automatic cleaning after the movable jaw plate and the static jaw plate are blocked.

[0017] The jaw crusher for fine crushing of spodumene can gradually apply opposite forces to the two rollers when the worm rotates, so that the two rollers drive the sliding rod and the L-shaped plate thereon to move away from each other. At this time, the tension spring will be stretched and deformed until the roller falls from the highest position on the S-shaped oscillation cam to the lowest position. At this time, the L-shaped plate drives the impact block to hit the feed port under the elastic force of the tension spring when stretched. When the impact block hits the feed port, it will generate a certain impact and vibration force, which can alleviate the blockage of spodumene ore inside the jaw crusher body to a certain extent, avoiding the problem that the traditional method of relying solely on mechanical force for cleaning cannot completely solve the blockage problem, improving the diversity and effectiveness of cleaning, combining mechanical and physical forces to jointly solve the blockage problem, so that the overall operating efficiency of the equipment is improved, and the downtime caused by blockage is reduced.

[0018] The jaw crusher for fine crushing of spodumene can drive the slider to rotate together through the fixed column when the chain is running, and the sliding plate and two sliding rails can make the rotating shaft always be driven vertically and parallel when the slider moves along the running track of the chain, so that it can move. When the slider moves to one side of the chain, the fixed column can drive the slider to move downward. At this time, the rotating shaft in the swing cleaning component will gradually probe downward into the interior of the jaw crusher body, which avoids the problem that the traditional cleaning method cannot reach the bottom of the blockage, resulting in incomplete cleaning and easy damage to equipment or materials during the cleaning process, thereby improving the thoroughness and efficiency of cleaning and reducing the loss during the cleaning process.

[0019] The jaw crusher for fine crushing of spodumene has a self-locking property when the worm and worm wheel arranged in the self-locking reduction transmission component are meshed, which can increase the torque of the motor rotation to a certain extent. This enables the chain to have a greater force when the worm wheel drives the sprocket shaft to rotate, thereby driving the rotating shaft in the swing cleaning component to probe downward into the internal blockage area of ​​the jaw crusher body, avoiding the problem of low transmission efficiency, insufficient cleaning force, and inability to effectively clean blockages in the traditional method, thereby improving the reliability and durability of the equipment and reducing equipment downtime caused by insufficient cleaning.

[0020] The jaw crusher for fine crushing of spodumene has a swinging material cleaning component that moves downward and also makes a reciprocating swinging motion, which enables the manganese steel tip at the lower end of the rotating shaft to easily drill to the bottom of the blocked area when it contacts the spodumene ore blocked in the jaw crusher body, and because the two sides of the lower edge of the arc-shaped hook plate are chamfered, when the rotating shaft moves downward and swings back and forth, the inclined surface on the arc-shaped hook plate will be retracted upward by the force of contact with the blocked spodumene ore, and the torsion spring will be compressed at this time until the manganese steel tip can move to the bottom of the spodumene ore blockage area.

[0021] The jaw crusher for fine crushing of spodumene can gradually move the swinging cleaning component obliquely upward under the continuous operation of the chain, so that the moving arc-shaped hook plate can clear the blocked spodumene ore. This avoids the problem of using manual or mechanical cleaning methods in traditional methods, which cannot penetrate into the bottom of the blockage, making it difficult to completely remove the blockage and resulting in poor cleaning effect. The dynamic cleaning method of reciprocating swinging can more thoroughly remove the blockage and improve the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Furthermore, the two L-shaped plates 35 are respectively fixedly connected to the opposite ends of the two sliding rods 33, and the ends of the two L-shaped plates 35 away from the sliding rods 33 are fixedly connected with impact blocks 36 for knocking the feed port 5, and tension springs 37 are fixedly connected between the two L-shaped plates 35 and the mounting plate 4.

[0033] Furthermore, a self-locking reduction transmission assembly is provided on the mounting plate 4 , and the self-locking reduction transmission assembly is used for transmission. The self-locking reduction transmission assembly includes two fixed shaft seats 29 .

[0034] Furthermore, two fixed shaft seats 29 are rotatably connected to the outer surface of the worm shaft 28, and a worm 30 is fixedly sleeved on the outer surface of the worm shaft 28. A worm wheel 26 is fixedly sleeved on the outer surface of a sprocket shaft 7 in the anti-blocking motion component, and the worm wheel 26 is meshingly connected to the worm 30.

[0035] Furthermore, when the movable jaw plate and the stationary jaw plate in the crusher feed port 5 are blocked during use, the motor 6 is started, and the output shaft of the motor 6 can drive the worm shaft 28 and the worm 30 and the S-shaped oscillation cam 31 thereon to rotate together, and the rotating worm 30 can drive the worm wheel 26 to rotate, and the rotating worm wheel 26 can drive the sprocket 8 to rotate through the sprocket shaft 7 thereon, so that the chains 9 on the multiple sprockets 8 can operate together, and when the chain 9 is operating, the slider 14 can be driven to rotate together through the fixed column 10 thereon, and the slider 14 moves along the operating trajectory of the chain 9. By setting the slide plate 13 and the two slide rails 11, the rotating shaft 16 can always be driven vertically and parallel, so that it can move. When the slider 14 moves to one side of the chain 9, the fixed column 10 can drive the slider 14 to move downward. At this time, the rotating shaft 16 in the swing cleaning component will gradually penetrate into the interior of the jaw coarse crusher body 1, which avoids the problem that the traditional cleaning method cannot reach the bottom of the blockage, resulting in incomplete cleaning and easy damage to equipment or materials during the cleaning process, thereby improving the thoroughness and efficiency of cleaning and reducing the loss during the cleaning process.

[0036] Furthermore, by the self-locking property of the worm 30 arranged in the self-locking reduction transmission assembly when meshing with the worm wheel 26, the torque of the motor 6 can be increased to a certain extent, which enables the chain 9 to have a greater force when the worm wheel 26 drives the sprocket shaft 7 to rotate, thereby driving the rotating shaft 16 in the swing cleaning assembly to penetrate downward into the internal blockage area of ​​the jaw coarse crusher body 1, thereby avoiding the problem of low transmission efficiency, insufficient cleaning force, and inability to effectively clean blockages in the traditional method, thereby improving the reliability and durability of the equipment and reducing equipment downtime caused by insufficient cleaning.

[0037] Furthermore, when the rotating shaft 16 moves up and down, the meshing of the gear 20 and the rack 27 can cause the gear 20 to rotate on its own, and drive the local bevel gear 21 on the gear shaft 19 to rotate together. When the local bevel gear 21 rotates, the local teeth on it can mesh with the bevel gear 17 on the upper side, thereby driving the bevel gear 17 to rotate clockwise by a certain angle, and then the local teeth on the rotating local bevel gear 21 begin to mesh with the bevel gear 17 on the lower side. At this time, the bevel gear 17 on the lower side can drive the rotating shaft 16 thereon to rotate counterclockwise by a certain angle, and the continuous rotation of the gear 20 can enable the rotating shaft 16 to complete continuous reciprocating swing. The swing cleaning component is provided to make a reciprocating swinging motion while moving downward, which enables the manganese steel tip 22 at the lower end of the rotating shaft 16 to make contact with the spodumene ore blocked in the jaw coarse crusher body 1, and the manganese steel tip 22 can drill to the bottom of the blocked area more easily, and because the positions on both sides of the lower edge of the arc-shaped hook plate 25 are chamfered, when the rotating shaft 16 moves downward and swings back and forth, the inclined surface on the arc-shaped hook plate 25 will be retracted upward by the force of contact with the blocked spodumene ore, and the torsion spring will be compressed at this time until the manganese steel tip 22 can move to the bottom of the spodumene ore blockage area.

[0038] Then, under the continuous operation of the chain 9, the swing cleaning assembly can gradually move obliquely upward, so that the moving arc-shaped hook plate 25 can clear the blocked spodumene ore, which avoids the problem of using manual or mechanical cleaning methods in traditional methods, which cannot penetrate into the bottom of the blockage, making it difficult to completely clear the blockage and resulting in poor cleaning effect. Through the dynamic cleaning method of reciprocating swinging, the blockage can be cleared more thoroughly and the cleaning effect is improved.

[0039] Furthermore, the swinging clearing component is also swinging back and forth when clearing the spodumene ore blocked in the jaw crusher body 1 obliquely upward, which enables the reciprocating arc-shaped hook plate 25 to pull the spodumene ore blocked in the jaw crusher body 1 to both sides and move it obliquely upward at the same time, so that the blocked spodumene ore can be effectively cleaned, avoiding the safety risks and low work efficiency brought by manual cleaning in the traditional way, and realizing automatic cleaning after the movable jaw plate and the static jaw plate are blocked.

[0040] Furthermore, when the worm 30 rotates, it can gradually apply opposite forces to the two rollers 34, so that the two rollers 34 drive the sliding rod 33 and the L-shaped plate 35 thereon to move away from each other. At this time, the tension spring 37 will be stretched and deformed until the roller 34 falls from the highest position on the S-shaped oscillation cam 31 to the lowest position. At this time, the L-shaped plate 35 is elastically acted upon by the tension spring 37 when stretched, and drives the impact block 36 to impact toward the feed port 5. When the impact block 36 hits the feed port 5, a certain impact and oscillation force will be generated, which can alleviate the blockage of spodumene ore inside the jaw coarse crusher body 1 to a certain extent, avoiding the problem that the blockage cannot be completely solved by simply relying on mechanical force in the traditional way, improving the diversity and effectiveness of cleaning, and combining mechanical and physical forces to jointly solve the blockage problem, so that the overall operating efficiency of the equipment is improved, and the downtime caused by blockage is reduced.

[0041] Working principle: when in use, when the movable jaw plate and the static jaw plate in the crusher feed port 5 are blocked, by starting the motor 6, the output shaft of the motor 6 can drive the worm shaft 28 and the worm 30 and the S-shaped oscillation cam 31 thereon to rotate together, and the rotating worm 30 can drive the worm wheel 26 to rotate, and the rotating worm wheel 26 can drive the sprocket 8 to rotate through the sprocket shaft 7 thereon, so that the chains 9 on multiple sprockets 8 can operate together, and when the chain 9 is running, the slider 14 can be driven to rotate together through the fixed column 10 thereon, and when the slider 14 moves along the operating trajectory of the chain 9, the slide plate 13 and the two slide rails 11 set can make the rotating shaft 16 always driven vertically and parallel, which can move, when the slider 14 moves to one side of the chain 9, the fixed column 10 can drive the slider 14 to move downward, at this time, the rotating shaft 16 in the swing cleaning assembly will gradually probe downward into the inside of the jaw coarse crusher body 1.

[0042] Furthermore, the self-locking property of the worm 30 arranged in the self-locking reduction transmission assembly when meshing with the worm wheel 26 can increase the torque of the motor 6 to a certain extent, so that when the worm wheel 26 drives the sprocket shaft 7 to rotate, the chain 9 can have a greater force, thereby driving the rotating shaft 16 in the swing cleaning assembly to penetrate downward into the blocked area inside the jaw crusher body 1.

[0043] Furthermore, when the rotating shaft 16 moves up and down, the meshing of the gear 20 and the rack 27 can cause the gear 20 to rotate on its own, and drive the local bevel gear 21 on the gear shaft 19 to rotate together. When the local bevel gear 21 rotates, the local teeth on it can mesh with the bevel gear 17 on the upper side, thereby driving the bevel gear 17 to rotate clockwise by a certain angle, and then the local teeth on the rotating local bevel gear 21 begin to mesh with the bevel gear 17 on the lower side. At this time, the bevel gear 17 on the lower side can drive the rotating shaft 16 thereon to rotate counterclockwise by a certain angle, and the continuous rotation of the gear 20 can enable the rotating shaft 16 to complete continuous reciprocating swing. The swing cleaning component is provided to make a reciprocating swinging motion while moving downward, which enables the manganese steel tip 22 at the lower end of the rotating shaft 16 to make contact with the spodumene ore blocked in the jaw coarse crusher body 1, and the manganese steel tip 22 can drill to the bottom of the blocked area more easily, and because the positions on both sides of the lower edge of the arc-shaped hook plate 25 are chamfered, when the rotating shaft 16 moves downward and swings back and forth, the inclined surface on the arc-shaped hook plate 25 will be retracted upward by the force of contact with the blocked spodumene ore, and the torsion spring will be compressed at this time until the manganese steel tip 22 can move to the bottom of the spodumene ore blockage area.

[0044] Then, under the continuous operation of the chain 9, the swing cleaning assembly can gradually move obliquely upward, which enables the moving arc-shaped hook plate 25 to clear the blocked spodumene ore.

[0045] Furthermore, the swinging cleaning component is also swung back and forth when clearing the spodumene ore blocked in the jaw crusher body 1 obliquely upward, which enables the reciprocating arc-shaped hook plate 25 to pull the spodumene ore blocked in the jaw crusher body 1 to both sides and move it obliquely upward at the same time, so that the blocked spodumene ore can be effectively cleaned.

[0046] Furthermore, when the worm 30 rotates, it can gradually apply opposite forces to the two rollers 34, so that the two rollers 34 drive the sliding rod 33 and the L-shaped plate 35 thereon to move away from each other. At this time, the tension spring 37 will be stretched and deformed until the roller 34 falls from the highest position on the S-shaped oscillation cam 31 to the lowest position. At this time, the L-shaped plate 35 is elastically acted upon by the tension spring 37 when stretched, and drives the impact block 36 to impact toward the feed port 5. When the impact block 36 hits the feed port 5, a certain impact and vibration force will be generated, which can alleviate the blockage of spodumene ore inside the jaw coarse crusher body 1 to a certain extent.
