Principle of operation

After feeder hopper 4 is poured into to the raw materials after the breakage, start first motor 7, drive first output shaft 704 and rotate, turn over the raw materials and send into down in spreading into feeder hopper 4 with power, it is rotatory through the last little band pulley 701 of first output shaft, it rotates to drive belt 703, belt 703 drives big band pulley 702 and rotates, in the screening mechanism 301 in the second box 3 with power input, it is rotatory to drive roller 302, further put preliminary broken raw materials in feeder hopper 4 on first sieve 303 and grind, the hole on the second sieve 304 staggers completely with first sieve 303 and third sieve 305 this moment, let the raw materials can't be down.

After the raw materials are ground, a second motor 316 is started to drive a second output shaft 313 to rotate, the second output shaft 313 drives a winch 314 to rotate, the winch 314 pulls a third sieve plate 305 to move downwards through a rope 315, a cross rod 306 moves towards the direction of the second sieve plate to drive a first piston rod 308 to move, force is transmitted to the second piston rod 311, the second piston rod 311 pushes a second sieve plate 304 to move between the first sieve plate 303 and the third sieve plate 305, so that the sieve holes can gradually increase in diameter, because the areas of the two ends of a hydraulic cylinder are different, the displacement distance of the second piston rod 311 is shorter than that of the first piston rod 308, when the three sieve plates move downwards, because a protrusion on a slide way in a guide groove of a vibration component 312 collides with rotating pins at the two ends of the cross rod 306, the three sieve plates vibrate integrally and are favorable for the falling of the raw materials, when the cross rod 306 moves downwards, when encountering a step with horizontal displacement, the distance that horizontal pole 306 promoted second sieve 304 can make the sieve mesh increase to the assigned diameter, the first step from top to bottom makes the sieve mesh diameter become 0.5mm by 0mm, and the second step makes the sieve mesh diameter become 1.5mm by 0.5mm, and the second step keeps 1.5mm diameter to the bottom slide always.

After the three sieve plates are moved downwards, the cross rod 306 moves to the side, away from the wall of the second box body 3, of the vibration part 312, at the moment, the second motor stops working, the three sieve plates are upwards turned up under the driving of the torsion springs, particles with the diameter larger than 1.5mm are turned back to the roller 302 for regrinding, meanwhile, the cross rod 306 supports against the outer wall of the vibration part 312 under the action of the spring on the shaft 307, in the process of moving upwards, the cross rod 306 passes through the step and can pass through the first piston rod 308 under the action of the spring, the piston cylinder 310 and the second piston rod 311 drive the second sieve plate 304 to move quickly, the raw materials clamped in the sieve holes can be crushed and shaken out, and when the cross rod 306 moves to the top, the next working process is circulated.

The cross rod 306 can trigger the sensors when moving through the steps in the vibration part 312, when the sensors detect that an object passes through, the third motor 903 can be started, the third motor 903 drives the gear 904 to rotate through the third output shaft 910, the gear 904 is in meshed transmission with the gear ring 905 to drive the barrel body 901 to rotate, cavities of raw materials of 0-0.5mm,0.5-1.5mm and 1.5mm in the barrel body 901 are correspondingly collected and aligned with the discharge port respectively, when the raw materials below 1.5mm account for more than 65% of the total amount of the whole raw materials, the corresponding induction valves 906 are controlled to be opened, so that the raw materials fall into the material trolley 8, and when all the raw materials with the three diameters fall into the material trolley 8, the material trolley 8 is pushed out through the doors.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
