The bearing screening apparatus of claim 4, wherein a first bevel gear (897) is fixedly connected to the outer surface of the upper end of the worm (893), a groove (896) is formed in the top end inside the sliding groove (895), the first conical gear (897) penetrates into the groove (896), a threaded hole (9) is formed in the position, close to the upper end, of the outer surface of the right side of the second supporting rod (894), a threaded rod (898) is connected with the internal thread of the threaded hole (9), a second bevel gear (899) is fixedly connected with the outer surface of the left side of the threaded rod (898), and a second bevel gear (899) penetrates into the groove (896), the first bevel gear (897) is meshed with the second bevel gear (899), the bottom end inside the sliding groove (895) is connected with a second bearing (10) in an embedded manner, and the outer surface of the lower end of the worm (893) is connected in the second bearing (10) in an embedded manner.

6. The bearing screening apparatus of claim 3, wherein the screening plates (82) are distributed in a plurality of numbers and have the same structure, the screening plates (82) are distributed between the first support rod (81) and the second support rod (894) in a staggered manner, universal wheels (12) are fixedly connected to the lower ends of the first support rod (81) and the second support rod (894), and a storage box body (11) is fixedly connected between the first support rod (81) and the second support rod (894) near the lower end.

7. A method of using a bearing screening apparatus as claimed in claim 1, the method including in particular the steps of:

the method comprises the following steps: firstly, steel balls are poured into the inner groove (4) from the feed opening (3), then the stirring rod (54) is driven to rotate by electrifying the rotating motor (53), and then the stirring paddle (55) and the grinding roller (56) are driven to rotate in the inner groove (4), so that the steel balls poured into the inner groove (4) can be effectively rotated and ground, and meanwhile, the grinding effect is further improved by using the grinding block (57) on the inner wall of the inner groove (4);

step two: when the stirring rod (54) rotates, the stirring paddle (591) is utilized to stir the steel balls at the lowest layer, so that the grinding is more uniform, and the grinding effect of the device is improved;

step three: while grinding, a worker twists the threaded rod (898) to enable the threaded rod (898) to drive the second bevel gear (899) to rotate, thereby driving the first conical gear (897) engaged with the worm to rotate, and the worm (893) rotates along with the rotation of the first conical gear (897), because the lower end of the worm (893) is embedded in the second bearing (10), the worm (893) can be effectively rotated, and when the worm (893) rotates, the worm block (891) of the thread on the surface of the worm moves downwards or upwards, thereby adjusting the inclination angle of the sieving plate (82) and clamping the left side of the sieving plate (82) in the fixing block (86), the fixed block (86) is hinged on the outer surface of the first supporting rod (81) by a hinge piece (89), thereby effectively inclining the angle of the screening plate (82) to facilitate the screening effect on the steel balls;

step four: after the regulation is accomplished, upwards rise through control electric telescopic handle (51), make it utilize connecting rod (52) and the connected mode of rotating motor (53) to upwards lift up rotating motor (53), break away from out opening (6) at resistance block (58) of the in-process puddler (54) lower extreme that lifts up to can fall into to sieve plate (82) through opening (6) with the steel ball after polishing on, thereby divide the sieve to the steel ball, and is simple in operation, and the work efficiency is improved.
