[0021] The same jetting frame 9 is fixedly connected to both sides of the main body 1. A jetting head 11 is fixedly connected to the top end of the jetting frame 9. An air pump 10 is fixedly connected to one side of the jetting head 11. Through the setting of the jetting head 11 and the air pump 10, the gas jetted by the jetting head 11 cleans the bearings, removes impurities, and is also beneficial for cooling;

[0022] A protective shell 12 is fixedly connected to one side of the main body 1. A servo motor 13 is arranged inside the protective shell 12. The output end of the servo motor 13 is fixedly connected to a rotating convex block 14. One side of the rotating convex block 14 is movably connected to a rotating concave block 15. A rotating block 16 is fixedly connected to the top end of the rotating concave block 15. A rotating rod 17 is fixedly connected to the outer arc surface of the rotating block 16. The number of the rotating rods 17 is four. A rod groove 25 is opened on one side of the main body 1. The rod groove 25 corresponds to the rotating rod 17. Through the setting of the rod groove 25 and the rotating rod 17, the rotating rod 17 rotates in the rod groove 25 to push the bearings, preventing the bearings from getting stuck on the conveyor belt;

[0023] One side of the main body 1 is movably connected with a placing tray 18. The bottom end of the placing tray 18 is fixedly connected with a sliding groove block 19. A moving rod 20 is connected in the sliding groove block 19 through a pin. The number of moving rods 20 is four. Two of the moving rods 20 are connected to the bottom end of the placing tray 18 through a pin shaft. The moving rods 20 are arranged in a pairwise cross-through manner through pins. The other end of the moving rod 20 is connected with a chassis 23 through a pin shaft. The top end of the chassis 23 is movably connected with a base fixing block 22.

[0025] The working principle of the present utility model is as follows: First, the bearing ring is placed on the automatic conveyor belt 2. When the automatic conveyor belt 2 moves at this time, the electric push rod 4 is started. One end of the electric push rod 4 pulls the push-pull rod 5. The push-pull rod 5 pulls the blocking plate 6 to move to block the bearing, so that the bearing ring moves in the middle of the automatic conveyor belt 2 to prevent the bearing ring from adhering to the inner side of the main body 1. At the same time, when there are a large number of bearings, by retracting the electric push rod 4, at this time, the torsion spring 8 will drive the rotating shaft 7 and the blocking plate 6 to reset, facilitating the bearings to always move in the middle of the automatic conveyor belt 2. When moving under the air jet frame 9, the air pump 10 is started, so that the gas ejected by the air jet head 11 cleans the bearings to remove impurities. When the bearings reach the corner, the servo motor 13 is started. The output end of the servo motor 13 drives the rotating convex block 14 to rotate. The protruding part of the rotating convex block 14 rotates to drive the rotating concave block 15 to rotate. When the rotating concave block 15 rotates, it drives the rotating block 16 at the top to rotate. The rotating block 16 drives the rotating rod 17 to rotate, so that the outer ring of the bearing enters the placing tray 18. At this time, the electric telescopic rod 21 can be started to push and pull the moving rod 20, so that the moving rod 20 moves in the sliding groove block 19 to adjust the height of the placing tray 18.
