The efficient crushing device for the lead grid casting waste residue with the particle size sieving mechanism as claimed in any one of claims 1 to 7, wherein the usage method of the efficient crushing device for the lead grid casting waste residue with the particle size sieving mechanism comprises the following steps:

the method comprises the following steps: waste residues are put into a feeding box (10), flow into a lifting machine (8) from the interior of a feeding pipe (9) at the lower end of the feeding box (10), flow out of a discharging pipe (11) after being lifted and fed by the lifting machine (8) and enter a feeding hopper (6), and then fall into a crushing box (20) for crushing treatment;

step two: in the feeding process, the crushing motor (21) is controlled to work, the crushing motor (21) drives the crushing roller (22) in the crushing box (20) to work, the waste residues slide down from the guide plate (23) and are crushed, the crushed waste residues fall onto the screening net (32) to be automatically screened, and the small-particle waste residues obtained through screening enter the recovery box (2) to be collected;

step three: when the crushing box (20) works, an external driving motor (12) is controlled to work, the driving motor (12) drives a concentric shaft (25) to rotate, the concentric shaft (25) drives a sector toothed plate (26) to synchronously rotate, and the sector toothed plate (26) drives a single-face toothed plate (27) to do up-and-down reciprocating motion through transmission between gears;

when sector toothed plates (26) on two sides of the crushing box (20) are meshed with the corresponding single-face toothed plates (27), the sector toothed plates (26) drive the single-face toothed plates (27) to vertically move downwards, the single-face toothed plates (27) drive the guide sliding blocks (28) to vertically slide downwards in sliding grooves in the crushing box (20), the guide sliding blocks (28) are enabled to extrude a lower reset spring (30) to generate elastic deformation, and a lower pressing plate (29) between the two guide sliding blocks (28) extrudes lower waste residues along with the downward movement of the guide sliding blocks (28), so that the crushing efficiency of the equipment is improved;

when the single-face toothed plate (27) vertically moves downwards, the single-face toothed plate (27) drives the sieving net (32) at the lower end to synchronously move, the sieving net (32) drives the limiting sliding block (33) to slide in the machining cover (1), when the sector toothed plate (26) is separated from the single-face toothed plate (27), the single-face toothed plate (27) is restored to the original position due to the influence of the restoring force of the reset spring (30) to drive the sieving net (32) to synchronously restore, and when the sector toothed plate is meshed again, the single-face toothed plate (27) is driven to move again, so that the sieving net (32) is favorable for continuously vibrating and sieving crushed waste residues;

step four: and when concentric shaft (25) rotated, concentric shaft (25) drove outside drive belt (13) and rotates, drive belt (13) drive belt pulley (15) and rotate in step, belt pulley (15) drive driven spindle (16) rotate in the inside of slide (18) down, make driven spindle (16) drive boosting wheel (17) carry out the boosting to the waste residue of big granule, promote once more through lifting machine (8) and carry out the regrinding after making the inside that large granule waste residue enters into recovery tube (19) from discharging hole, help further improve equipment's crushing effect.
