[0021] Compared with the prior art, the lithium spodumene fine crushing jaw crusher has the following beneficial effects:

[0022] The lithium spodumene fine crushing jaw crusher, when unblocking the lithium spodumene ore blocked in the jaw crusher body, also reciprocally swings, so that the arc-shaped hook plates reciprocally swing to spread the lithium spodumene ore in the jaw crusher body to both sides and simultaneously move upward, which effectively unblocks the lithium spodumene ore, avoids the safety risks and low work efficiency caused by manual unblocking in the traditional way, and realizes automatic unblocking of the dynamic jaw plate and the static jaw plate after being blocked.

[0023] When the worm rotates, the lithium spodumene fine crushing jaw crusher can gradually apply opposite forces to the two rollers, so that the two rollers drive the sliding rods and L-shaped plates thereon to move away from each other, at this time, the tension spring is 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 impact the feed inlet under the elastic force of the tension spring, and the impact block impacts the feed inlet to generate a certain impact oscillation force, which can relieve the blockage of the lithium spodumene ore in the jaw crusher body to a certain extent, avoid the problem that the mechanical force alone cannot completely solve the blockage in the traditional way, improve the diversity and effectiveness of unblocking, and solve the blockage problem by combining mechanical and physical forces, so that the overall operation efficiency of the equipment is improved, and the downtime caused by blockage is reduced.

[0024] When the chain rotates, the lithium spodumene fine crushing jaw crusher can drive the sliding block to rotate through the fixed column thereon, and when the sliding block moves along the rotation track of the chain, the sliding block can be driven to be always perpendicular and parallel to the rotating shaft through the sliding groove plate and the two sliding rails, so that the rotating shaft can be moved downward when the sliding block moves to one side of the chain, and the rotating shaft of the swinging unblocking assembly can gradually penetrate into the interior of the jaw crusher body, which avoids the problem that the traditional unblocking method cannot penetrate to the bottom of the blockage, causes incomplete unblocking, and easily damages the equipment or the material during the unblocking process, improves the completeness and efficiency of unblocking, and reduces the loss during the unblocking process.

[0025] The e-type coarse crusher for spodumene fine breaking has the self-locking nature when the worm and the worm gear mesh in the self-locking speed reduction transmission assembly, which can increase the torque of the motor to a certain extent, so that the chain has a larger force when the worm gear drives the sprocket shaft to rotate, thereby driving the rotating shaft in the swing material cleaning assembly to probe into the blocked area inside the e-type coarse crusher body, avoiding the problems of low transmission efficiency, insufficient cleaning force and ineffective cleaning of the blockage in the traditional way, improving the reliability and durability of the equipment and reducing the downtime of the equipment due to insufficient cleaning.

[0026] The e-type coarse crusher for spodumene fine breaking, through the swing material cleaning assembly, moves downward while also making reciprocating swing movement, which can make the manganese steel sharp tip at the lower end of the rotating shaft contact the blocked spodumene ore in the e-type coarse crusher body, and the manganese steel sharp tip can easily drill to the bottom of the blocked area, and the lower edge of the arc-shaped hook plate is chamfered, which can make the slope on the arc-shaped hook plate retract upward under the action of the force of the blocked spodumene ore when the rotating shaft moves downward and reciprocating swings, and the torsional spring is compressed at this time until the manganese steel sharp tip can move to the bottom of the blocked spodumene ore area.

[0027] The e-type coarse crusher for spodumene fine breaking makes the swing material cleaning assembly gradually move upward under the continuous operation of the chain, which makes the moving arc-shaped hook plate dredge the blocked spodumene ore, which avoids the problems of the traditional manual or mechanical cleaning method that cannot reach the bottom of the blockage, making it difficult to completely remove the blockage, and the poor cleaning effect, and the dynamic cleaning method of reciprocating swing can more completely remove the blockage and improve the cleaning effect.

[0064] Then, under the continuous operation of the chain 9, the swinging material cleaning assembly can gradually move upward and obliquely, which makes the moving arc-shaped hook plate 25 dredge the blocked spodumene ore.

[0065] Further, when the swinging material cleaning assembly dredges the blocked spodumene ore in the jaw crusher body 1 upward and obliquely, it also reciprocates, which can make the reciprocating arc-shaped hook plate 25 spread the blocked spodumene ore in the jaw crusher body 1 to both sides and simultaneously move obliquely upward, which makes the blocked spodumene ore be effectively cleaned.

[0066] Further, 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 to move away from each other, at this time the tension spring 37 is 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 drives the impact block 36 to impact into the inlet 5 under the elastic force of the stretched tension spring 37, and the impact block 36 impacts the inlet 5 to produce a certain impact oscillation force, which can relieve the blockage of the spodumene ore in the jaw crusher body 1 to a certain extent.
