DETAILED DESCRIPTION
[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] The utility model embodiment discloses a device suitable for screening micro steel balls.
[0024] The utility model provides Figure 1-3 A micro steel ball screening device shown includes a base 1, the upper surface of the base 1 is rotatably connected to two first rotating rods 2, the upper ends of the two first rotating rods 2 are obliquely provided with screening tubes 3, the upper surface of the base 1 is provided with an adjustment mechanism, the two screening tubes 3 are moved by the adjustment mechanism, the upper surface of the base 1 is fixedly connected to a plurality of support columns 4, the upper end of each support column 4 is commonly fixedly connected to a storage frame 5, the lower end of the storage frame 5 is provided with a discharge port, the inside of the discharge port is fixedly connected to a discharge pipe 6, and the inside of the storage frame 5 is provided with a stirring mechanism.
[0025] The micro steel balls can be rolled by using two tilted screening tubes 3, and the two screening tubes 3 can be moved and adjusted by using the adjustment mechanism, so that the distances between the two ends of the two screening tubes 3 are different. Then the micro steel balls are put between the two screening tubes 3, and then the steel balls will roll to the other side of the two screening tubes 3. At this time, the steel balls larger than the standard size can roll directly to the other end of the screening tube 3, and the steel balls smaller than the standard size will fall at the beginning of rolling, and the steel balls of the standard size will fall in the middle position of the screening tube 3, thereby completing the screening work.
[0026] In order to make the two screening tubes 3 movable, as Figure 1-2 As shown, the adjustment mechanism includes a bidirectional screw rod 7, two first sliders 8, two support rods 9, a rotating shaft 10, an articulated seat 12, a second slider 13, two mounting plates 14 and two slide rods 15. A groove is provided on the upper surface of the base 1. The bidirectional screw rod 7 is rotatably connected to the inside of the groove. The two first sliders 8 are respectively threadedly sleeved on the rod walls at both ends of the bidirectional screw rod 7. The two support rods 9 are respectively fixedly connected to the upper surfaces of the corresponding first sliders 8. The two rotating shafts 10 are respectively rotatably connected to the upper ends of the corresponding support rods 9. The two articulated seats 12 are respectively fixedly connected to the upper ends of the rotating shafts 10. The two mounting plates 14 are respectively fixedly connected to the bottom of the corresponding screening tubes 3. The two slide rods 15 are respectively fixedly connected between the corresponding two mounting plates 14. The two second sliders 13 are respectively slidably sleeved on the rod walls of the corresponding slide rods 15. The ends of the two articulated seats 12 away from the rotating shafts 10 are respectively fixedly connected to the lower surfaces of the corresponding second sliders 13. One end of the bidirectional screw rod 7 passes through one side of the groove and is fixedly connected with a knob 11.
[0027] The knob 11 is rotated to rotate the bidirectional screw rod 7 , and then the two first slide blocks 8 can be moved, so that the two support rods 9 can drive the corresponding screening tubes 3 to move, so as to adjust the distance between one ends of the two screening tubes 3 .
[0028] In order to prevent the steel balls from clogging, Figure 1 As shown, the stirring mechanism includes a support bar 16, a second rotating rod 17, a plurality of stirring rods 18 and a motor 20. The support bar 16 is fixedly connected to the inside of the material storage frame 5. The second rotating rod 17 is rotatably connected to the lower surface of the support bar 16. The motor 20 is fixedly connected to the upper surface of the support bar 16. The upper end of the second rotating rod 17 passes through the lower surface of the support bar 16 and is fixedly connected to the output end of the motor 20. Each stirring rod 18 is symmetrically fixedly connected to the rod wall of the second rotating rod 17. The rod wall of the second rotating rod 17 is symmetrically fixedly connected with an L-shaped scraper 19. The two L-shaped scrapers 19 are both in contact with the inner wall of the material storage frame 5.
[0029] The motor 20 is started to rotate the second rotating rod 17, and then each stirring rod 18 rotates, thereby preventing the steel balls from being blocked inside the storage frame 5. In this process, the steel balls close to the inner wall of the storage frame 5 can be moved by the L-shaped scraper 19.
[0030] Finally, in order to facilitate the falling of the steel ball, Figure 1 As shown, the lower end of the material storage frame 5 is in an inverted cone shape.
[0031] The inverted tapered material storage frame 5 makes it easier for the steel balls to roll and thus easier for the steel balls to fall.
[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
