Referring to fig. 1-6, the present invention provides a technical solution: the utility model provides a reducing mechanism of adjustable particle diameter, includes casing 1, the upper end of casing 1 is opened has and is used for waiting the feed inlet 101 that kibbling ore was poured into in casing 1, below one side of feed inlet 101 is equipped with fixed jaw 2, just the below opposite side of feed inlet 101 articulates there is movable jaw 3, and the upper end of movable jaw 3 is rotated and is connected on the lateral wall of casing 1, leaves the crushing clearance of smashing the ore between fixed jaw 2 and the movable jaw 3, through the activity of movable jaw 3, can make fixed jaw 2 and movable jaw 3 extrude the ore to the realization is to the crushing of ore, one side fixedly connected with support 4 of casing 1, be equipped with on support 4 and be used for driving movable jaw 3 reciprocating swing's drive assembly 5, open the below of casing 1 has and is used for discharging the outer discharge gate 102 of casing 1 with kibbling ore granule;

as shown in fig. 2, to wait that kibbling ore pours into the inside of casing 1 from feed inlet 101, the ore that gets into the inside of casing 1 can fall between fixed jaw 2 and movable jaw 3 earlier, drive through drive assembly 5, make movable jaw 3 reciprocating swing, fixed jaw 2 extrudees the ore with movable jaw 3, thereby the realization is to the crushing of ore, kibbling ore granule can be followed discharge gate 102 and discharged, in addition, the below of discharge gate 102 can be equipped with the outside transportation area and be used for transporting kibbling ore granule.

As shown in fig. 2, 3, and 5, in order to drive the movable jaw 3 to swing back and forth, specifically, the driving assembly 5 includes a base 501, the base 501 is disposed on a side wall of the support 4, and a flywheel 503 is rotatably connected to the side wall of the base 501 through a motor 502, as shown in fig. 5, the motor 502 is fixedly mounted on the side wall of the base 501, an output shaft of the motor 502 is connected to a rotating shaft of the flywheel 503 through a belt, so that when the motor 502 is started, the output shaft of the motor 502 drives the flywheel 503 to rotate, a swing rod 504 is rotatably connected to the side wall of the flywheel 503, one end of the swing rod 504, which is far away from the flywheel 503, penetrates through a side wall of the housing 1 and is rotatably connected to a side wall of the movable jaw 3, and the swing rod 504 drives the movable jaw 3 to swing under rotation of the flywheel 503;

as shown in fig. 2, when the motor 502 is started, the motor 502 drives the flywheel 503 to rotate on the base 501, so that one end of the swing rod 504 makes a circular motion along with the rotation of the flywheel 503, and thus the swing rod 504 drives the movable jaw 3 to swing back and forth, the fixed jaw 2 and the movable jaw 3 squeeze ore, thereby crushing the ore,

as shown in fig. 3 and 5, in order to adjust the size of the crushing gap between the movable jaw 3 and the fixed jaw 2, and to adjust the particle size of the crushed ore, specifically, a plurality of guide rods 6 are fixedly connected to the side wall of the support 4, the guide rods 6 are arranged in parallel, the base 501 is slidably sleeved on the guide rods 6, and the side wall of the support 4 is rotatably connected with a lead screw 7 for driving the base 501 to slide, as shown in fig. 3, the base 501 is engaged and sleeved on the lead screw 7, after the lead screw 7 is rotated, the lead screw 7 drives the base 501 to slide on the guide rod 6, and when the base 501 slides, the flywheel 503 is driven to slide towards or away from one side of the movable jaw 3, so that the movable jaw 3 can swing under the driving of the swing rod 504, so as to adjust the crushing gap between the movable jaw 3 and the fixed jaw 2, and then adjust the particle size of the crushed ore.

As shown in fig. 3, in order to avoid the lead screw 7 rotating on the bracket 4 by itself to prevent the particle size of the crushed ore from changing, specifically, a locking bolt 8 is engaged and connected to the side wall of the bracket 4, and a threaded end of the locking bolt 8 penetrates through the side wall of the bracket 4 and is pressed against the side wall of the lead screw 7;

when the particle size of smashing the ore granule is adjusted to needs rotation lead screw 7, loosen locking bolt 8 earlier, make the not roof pressure of the screw thread end of locking bolt 8 on the lateral wall of lead screw 7, can freely rotate lead screw 7 this moment, can adjust smashing the ore granule particle size like this, adjust the back that finishes, screw up locking bolt 8, make the screw thread end of locking bolt 8 roof pressure once more after on the lateral wall of lead screw 7, cause lead screw 7 can not rotate by oneself (the vibrations that produce when smashing the ore granule), effectively prevent when smashing the ore granule, it changes to smash the ore granule particle size.

As shown in fig. 4, in order to further improve the efficiency of crushing the ore particles, specifically, crushing teeth 9 are fixedly connected to the side walls of the fixed jaw 2 and the movable jaw 3, and when crushing the ore particles, the crushing teeth 9 can crush the ore more easily into small pieces when pressing the ore.

As shown in fig. 4, in order to prevent hard substances from being stuck in the crushing gap due to being unable to crush, specifically, a plurality of first guide posts 10 are fixedly connected to a side wall of the fixed jaw 2, the plurality of first guide posts 10 are respectively slidably sleeved on a side wall of the housing 1, and a first spring 11 for urging the fixed jaw 2 toward one side of the movable jaw 3 is sleeved on the first guide posts 10;

when smashing the ore, hard material in the ore can not smashed, and movable jaw 3 this moment is when the hard material of extrusion, and first spring 11 can be compressed, smashes the clearance like this and can increase to can make and smash hard material whereabouts in the clearance, avoid hard material card in smashing the clearance, break away from the back when hard material breaks away from smashing the clearance, first spring 11 resets, thereby makes fixed jaw 2 and movable jaw 3 normally to the crushing operation of ore.

As shown in fig. 2, in order to screen out ore particles which are not crushed thoroughly, specifically, a discharge opening 103 is formed in one side wall of the casing 1, an inclined sieve plate 12 is arranged inside the casing 1 and below the fixed jaw 2 and the movable jaw 3, the bottom end of the sieve plate 12 penetrates through the discharge opening 103 and extends to the outside of the casing 1, a plurality of second guide pillars 13 are fixedly connected below the sieve plate 12, the plurality of second guide pillars 13 are slidably connected to the side wall of the casing 1, and second springs 14 for upwards biasing the sieve plate 12 are sleeved on the plurality of second guide pillars 13;

after fixed jaw 2 and movable jaw 3 smashed the ore granule, the ore granule just can fall on sieve 12, smash qualified ore granule this moment and can pass in the mesh in sieve 12, and discharge through discharge gate 102, smash unqualified (granule is great, for example, the hard material that can't be broken) material can be intercepted by sieve 12, and discharge to casing 1 along bin outlet 103, realize getting rid of the hard material in the ore, in addition, when the ore granule falls on sieve 12, through the effect of second spring 14, sieve 12 can vibrate, thereby can further accelerate sieve 12 sieve efficiency of straining the ore granule.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
