Furthermore, the sieve holes formed by the staggering of the first and second sieve holes are not standard circles, making it difficult to achieve an effective sieving effect. Utility Model Content

[0005] In view of the problems existing in a current adjustable screening device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an adjustable screening device that solves the problems existing in the above-mentioned patents. By staggering the corresponding second screen holes of multiple first screen holes, the aperture of the screen holes can be adjusted. However, the adjustment between the first screen holes and the second screen holes is not convenient for precise control and it is difficult to accurately determine the aperture of the screen holes. Furthermore, the screen holes formed by the staggering of the first screen holes and the second screen holes are not standard circles, making it difficult to form an effective screening effect.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] An adjustable screening device includes a screening cylinder mounted on a support, and multiple screening mechanisms are arranged at equal intervals inside the screening cylinder.

[0009] The screening mechanism includes a screening plate, one end of which is hinged to the inner wall of the screening cylinder.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1: This utility model provides an adjustable screening device. Please refer to [link / reference]. Figure 1-4The screen includes a screening cylinder 1, which has a discharge port at the bottom and a cover 2 at the top. The screen is mounted on a support and has multiple screening mechanisms arranged at equal intervals inside.

[0028] The screening mechanism includes a screening plate 11. One end of the screening plate 11 is hinged to the inner wall of the screening cylinder 1 via a hinge 15. An electric push rod 12 is hinged together between the screening plate 11 and the inner wall of the screening cylinder 1. Specifically, a first hinge block 13 is welded to the bottom of the screening plate 11, and a second hinge block 14 is welded to the inner wall of the screening cylinder 1. The two ends of the electric push rod 12 are respectively hinged to the first hinge block 13 and the second hinge block 14 via pins. The aperture of the screen holes on the screening plate 11 in each screening mechanism is different. The aperture of the screen holes on each screening plate 11 is set according to the particle size of the particles that are frequently screened. That is, the aperture of the screen holes on each screening plate 11 is set according to several commonly used screen holes.

[0029] A sealing ring 10 is bonded to the inner wall of the screening cylinder 1. The top surface of the sealing ring 10 is an arc-shaped surface, and the sealing ring 10 and the screening plate 11 are elastically pressed together.

[0030] The support includes a first support column 5, the bottom of which is connected to a bottom support plate 3. Specifically, a support connecting seat 4 is fixed to the bottom support plate 3 by bolts. The first support column 5 is inserted into the inner wall of the support connecting seat 4 and fixed to the first support column 5 by bolts. A support plate 6 is fixedly installed on the first support column 5. A vibrator 7 is fixedly installed on the support plate 6. A first fixing plate 9 is fixedly connected to the top of the vibrator 7. The first fixing plate 9 is welded to the outer wall of the screening cylinder 1. A second fixing plate 8 is welded to the screening cylinder 1. Both the first fixing plate 9 and the second fixing plate 8 have through holes with a diameter larger than that of the first support column 5. The first support column 5 passes through the through holes on the first fixing plate 9 and the second fixing plate 8.

[0031] In practical use:

[0032] Select the screening plate 11 with the corresponding aperture, such as the bottom screening plate 11. At this time, the electric push rods 12 in the upper screening mechanisms retract, thereby driving the upper screening plates 12 to rotate to the tilt.

[0033] Material is injected into screening cylinder 1 and falls onto the bottom screening plate 11. Vibrator 7 works to make screening cylinder 1 vibrate, thereby accelerating the screening of material.

[0034] Particles larger than the screen aperture that are screened out are discharged through the discharge port at the bottom of the screening cylinder 1 and collected; finally, the electric push rod 12 at the bottom retracts, causing the screening plate below to tilt and discharge the material larger than the screen aperture.

[0035] Example 2, see attached document Figure 5Unlike Embodiment 1, the support includes a second support column 24 rotatably connected to the screening cylinder 1. An L-shaped support plate 19 is welded to the second support column 24 on the right side. A motor 21 is fixedly installed on the L-shaped support plate 19. An L-shaped drive rod 22 is welded to the end of the output shaft of the motor 21. A sleeve 23 is rotatably connected to the end of the L-shaped drive rod 22. Specifically, a support ring 231 is welded to the outer wall of the sleeve 23. The support ring 231 is rotatably connected to the L-shaped drive rod 22 through a bearing. A swing rod 20 is slidably connected to the inner wall of the sleeve 23. The end of the swing rod 20 is connected to a first pin 17. Specifically, a ring 18 is welded to the swing rod 20. The end of the first pin 17 is inserted into the ring 18, and the ring 18 and the first pin 17 are fixed together by bolts. The first pin 17 is rotatably connected to the second support column 24 on the right side through a bearing, and the end of the first pin 17 is welded to the screening cylinder 1.

[0036] A second pin 16 is welded to the left end of the screening cylinder 1, and the second pin 16 is rotatably connected to the second support column 24 on the left side through a bearing.

[0037] During the screening process, the motor 21 drives the L-shaped drive rod 22 to rotate, which in turn drives the sleeve 23 to make a circular motion, thereby driving the swing rod 20 to swing back and forth, which in turn causes the screening cylinder 1 to swing back and forth, thereby accelerating the screening speed of the material.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
