The implementation principle of the embodiment is as follows:

when stone needs to be classified and sieved, water is sprayed towards the stone to be fed into the feed cylinder 24 through the feed water spraying pipe 224, the surface of the stone is wet as much as possible, so that dust raised when the stone collides with the feed cylinder 24 is reduced, the stone is fed into the feed cylinder 24 through the feed port 241, the stone enters the feed cylinder 24 and then enters the conveying pipe 26 through the hopper 25, the stone enters the feed pipe 3 along the conveying pipe 26 and enters the sieve pipe 43 through the feed pipe 3, the driving device 45 is started, the rotating shaft is driven to rotate through the driving device 45, the driving gear 451 rotates through the rotation of the rotating shaft, so that the driving gear 451 drives the driven toothed ring 432 to rotate, as the driven toothed ring 432 is fixedly connected with the inner side wall of the sieve pipe 43, the sieve pipe 43 rotates along the axial direction of the sieve pipe 43, the stone with a smaller diameter than the diameter of the sieve hole 431 is thrown out to the inner side of the fixed cylinder 4 through the sieve hole 431 under the action On the wall, becoming undersize products, then gathering towards the opening end of the fixed cylinder 4 along the inclined direction of the fixed cylinder 4, and discharging outside through the main discharging pipe 5 arranged on the side wall of the fixed cylinder 4, stone with larger grain diameter than the aperture of the sieve hole 431 collides with the side wall of the sieve pipe 43 along the axial direction of the sieve pipe 43 along with the sieve pipe 43, so that dust and stone adhered on the surface of the stone are easy to separate from the outer wall of the stone, the dust and the stone are subject to centrifugal force during rotation and permeate through the sieve hole 431, and are discharged along with the undersize products, because the main discharging pipe 513 on the inner side wall of the main discharging pipe 5 sprays water towards the stone in the main discharging pipe 5, the dust and the outer wall of the stone are drenched under the action of water flow, the residual stone moves to the opening end of the fixed pipe along the inner side wall of the sieve pipe 43, becoming oversize products, and is discharged by the auxiliary discharging pipe 6, because the, make building stones outer wall and remaining dust drenched to make the difficult dust that raises behind the building stones discharge, thereby reduce the pollution to the air in the hierarchical high-efficient screening machine use of building stones, thereby improve the hierarchical operational environment near high-efficient screening machine of using of building stones.

Through the setting of baffle 46, make building stones along the inside wall of fixed cylinder 4 when sliding towards the open end of fixed cylinder 4 easy and the terminal surface of auxiliary bearing 42 towards fixed cylinder 4 bumps, because baffle 46 is cyclic annular and baffle 46's inner ring curved surface in spacing groove 433, make baffle 46 shelter from the bearing comparatively completely, thereby make building stones collide with baffle 46, make building stones and auxiliary bearing 42 be difficult for bumping, thereby make auxiliary bearing 42 be difficult for impaired, make auxiliary bearing 42 keep normal work, thereby reduce the building stones and cause the influence to the rotation of a sieve section of thick bamboo.

Through the setting of support 1, because the stable connection of hopper 25 is on main tributary vaulting pole 11, the stable connection of solid fixed cylinder 4 is on vice bracing piece 12 and secondary support pole 13 for hopper 25 and solid fixed pipe are difficult for taking place to remove in the relative position when receiving the building stones striking, because feed arrangement 2 and solid fixed pipe pass through conveying pipe 3 fixed connection, make conveying pipe 3 difficult impaired, thereby make the connection of conveying pipe 3 more stable, make the building stones difficult to spill from conveying pipe 3.

Through the matching of the driving gear 451 and the driven gear ring 432, when the driving device 45 drives the rotating shaft to rotate, the driving gear 451 rotates around the axial direction of the rotating shaft along with the rotating shaft, the driving gear 451 is meshed with the driven gear ring 432 to drive the driven gear ring 432 to rotate, since the driven ring 432 is fixedly attached to the screen 43, the screen 43 is rotated around the axial direction of the screen 43, because the stones with smaller grain sizes are easy to adhere to the stones with larger grain sizes, the stones in the sieve tube 43 collide with the inner side wall of the sieve tube 43 in the process that the stones rotate around the axial direction of the sieve tube 43 along with the sieve tube 43, so that the stones with smaller grain sizes are easy to separate from the stones with larger grain sizes, meanwhile, the stones with the particle sizes smaller than the aperture of the sieve holes 431 fall onto the inner side wall of the fixed cylinder 4 through the sieve holes 431 in the rotating process to become undersize products, so that the screening effect of the stones is better.

Through the cooperation of baffle 46 and spacing groove 433, because vice bearing 42 fixed connection is at the solid fixed cylinder 4 open end, when building stones along the solid fixed cylinder 4 inside wall towards the solid fixed cylinder 4 open end motion, building stones on the solid fixed cylinder 4 lateral wall are on baffle 46 in direct striking, because baffle 46 keeps away from solid fixed cylinder 4 inner ring curved surface and is located spacing groove 433, make the sheltering from of baffle 46 to vice bearing 42 towards the inside terminal surface of solid fixed cylinder 4 comparatively complete, make the building stones difficult to cross baffle 46, thereby make the building stones difficult and vice bearing 42 towards the inside side of solid fixed cylinder 4 bump, thereby make vice bearing 42 difficult impaired, make vice bearing 42 more stable with being connected of solid fixed cylinder 4 and screen pipe 43 simultaneously, thereby make screen pipe 43 keep normal rotation.

Through the setting of feeding spray set 22, because the building stones have the dust in, make the dust easily raise when the building stones collide with the 24 inside walls of feed cylinder, spray water towards the building stones before the building stones get into feed cylinder 24 for part building stones dust on the surface becomes moist, thereby makes the dust gathering, makes the dust difficult to raise, thereby reduces the pollution of dust to the air.

Through the setting of vice spray set 61, partial building stones are for being in for moist state, and the building stones easily collides with 6 inside walls of vice discharging pipe in ejection of compact in-process, through vice spray set 61's the effect of spraying, makes the dust of adhesion on the building stones difficult for flying in the collision in-process, thereby makes because the dust of the building stones uplift of 6 roll-offs of vice discharging pipe is less, thereby makes the pollution of reduction dust to the air, improves the environmental quality around the construction.

Leave gapped setting between 3 and driving gear and the driven ring gear through conveying pipe, when making driving gear 451 drive driven ring gear 432 rotate, conveying pipe 3 does not produce direct contact with driving gear 451 and driven ring gear 432, make conveying pipe 3 be difficult to produce the friction with 451 driving gear and driven ring gear 432, thereby make the difficult damage of conveying pipe 3 near driven ring gear 432 even fracture, make the difficult quilt of building stones in the conveying pipe 3 pound from conveying pipe 3 and fall to driven ring gear 432 on, thereby make driven ring gear 432 be difficult for impairedly, make drive arrangement 45 drive screen pipe 43 keep normal rotation.

Through setting of sieve mesh 431, when the building stones rotates around sieve tube 43 axial direction along with sieve tube 43, because sieve mesh 431 distributes on sieve tube 43 keeps away from the inside wall of base bearing 41, the less building stones of particle size falls on the inside wall that fixed cylinder 4 kept away from base bearing 41 from sieve mesh 431, make building stones difficult and base bearing 41 towards the terminal surface of fixed cylinder 4 open end and collide, thereby make base bearing 41 difficult impaired, make the dust of taking up in sieve tube 43 because of building stones rotation difficult attached to in base bearing 41, thereby the normal rotation of base bearing 41 inner ring is difficult for receiving the influence, make sieve tube 43's rotation difficult for receiving the influence, thereby make the efficiency of building stones screening in-process keep higher level.

Through the setting of main bearing 41 for sealed bearing, when the building stones rotates along the lateral wall of screen pipe 43 along the screen pipe 43 along with the building stones and makes the dust that the building stones carried fly in screen pipe 43, the bearing is in encapsulated situation for the dust is difficult to fly to the bearing in through the bearing, thereby makes the roll that influences ball in the bearing be difficult for receiving the influence of dust, and then makes the dust be difficult for floating to drive arrangement 45 on, makes the difficult dust that piles up on the drive arrangement 45.

Through the setting of main bearing 41 and auxiliary bearing 42, because the screen pipe 43 rotates through main bearing 41 and auxiliary bearing 42 and connects in fixed cylinder 4, make the stress point of screen pipe 43 and fixed cylinder 4 increase through the tie point that increases screen pipe 43 and fixed cylinder 4, make the atress dispersion of screen pipe 43 on fixed cylinder 4, thereby make the connection of screen pipe 43 and fixed cylinder 4 more stable, and because auxiliary bearing 42 fixed connection is at the fixed cylinder 4 open end, when the building stones move towards fixed cylinder 4 open end, certain less building stones of particle size need move one section distance and just fall to fixed cylinder 4 inside wall from screen hole 431, thereby the longer building stones of motion path that makes also can enter main discharging pipe 5 after the screening, make the screening of screen pipe 43 building stones more abundant, thereby make the screen pipe 43 more efficient to the grading of building stones.
