[0002] Urethane sieve plate is a mesh product made of polyurethane as raw material. It is mainly used in light screening occasions. It can achieve a good screening effect on fine particles in the material and can also be used for material dehydration. The hole shapes of the sieve plate are: slit, rectangle, circle, and square.

[0003] In the process of using a sieve plate to screen materials, sometimes when the sieve plate is screening the materials, there will be moisture in the materials, causing the materials to adhere to the sieve holes when passing through the sieve holes of the sieve plate. When the materials adhere to the inside of the sieve holes, they will interfere with the subsequent passing materials, which can easily cause the sieve holes to be blocked. In addition, the size of the existing sieve plate aperture cannot be adjusted, resulting in the need to replace sieve plates with different apertures when screening materials with different particles, which has low practicality.

A limiting slider 24 is fixedly provided on the outer surface of the round rod 21. A cylinder 22 is fixedly provided on the upper surface of the square frame 26. A limiting groove 23 is provided on the outer surface of the cylinder 22. The limiting slider 24 passes through the limiting groove 23. The limiting slider 24 slides and fits with the inner surface of the limiting groove 23. A spring 25 is fixed between the inner surface of the cylinder 22 and the lower surface of the round rod 21. A hollow support block 27 is fixedly provided on the upper surface of the square frame 26. A motor 28 is fixedly provided inside the hollow support block 27. Two motors 28 are provided. The two motors 28 can be started synchronously by a controller. The output end of the motor 28 is provided with a cam 281, and a protrusion 29 is fixedly provided on the lower surface of the sieve plate body 1. The cam 281 is in rotational contact with the inner surface of the protrusion 29. In order to prevent the sieve plate body 1 from being blocked, the motor 28 can be started to rotate the cam 281. The cam 281 rotates and is in rotational contact with the arc groove 291 provided in the protrusion 29, which can lift the sieve plate body 1. The round rod 21 slides along the inner surface of the cylinder 22, and the spring 25 is stretched. When the protrusion 29 is no longer in contact with the arc groove 291, the sieve plate body 1 can be quickly returned to its original position by the force of the spring 25. When the limiting slider 24 is in contact with the bottom of the limiting groove 23, vibration can be generated, thereby preventing the sieve plate body 1 from being blocked and improving the screening efficiency.

[0022] An arc-shaped groove 291 is provided on the lower surface of the protrusion 29, and the cam 281 is rotatably fitted with the inner surface of the arc-shaped groove 291 to facilitate lifting the protrusion 29. A discharge cylinder 11 is fixedly provided on the lower surface of the sieve plate body 1, and the outer surface of the discharge cylinder 11 is movably fitted with the inner surface of the square frame 26 to assist in unloading the material and prevent the material from falling on the square frame 26. A mounting plate 3 is fixedly provided on the side of the square frame 26, and a mounting bolt 31 is threadedly inserted on the mounting plate 3. The sieve plate body 1 is installed in the mounting groove of the equipment through the mounting plate 3 and the mounting bolt 31. Two lifting rods 32 are fixed on the upper surface of the square frame 26. The two lifting rods 32 are symmetrically arranged on the upper surface of the mounting plate 3 to facilitate lifting the square frame 26.

[0023] The adjusting assembly 4 includes a side groove 41, and the side groove 41 is opened on the side surface of the sieve plate body 1, and a second sieve plate 42 is slidably provided in the side groove 41, and a square groove 43 is opened on the inner surface of the side groove 41, and a first fixing block 44 is fixedly provided on the inner surface of the square groove 43, and a first screw 45 is rotatably provided between the first fixing block 44, and the outer surface of the first screw 45 is threadedly sleeved with a square sleeve 46, and the square sleeve 46 is fixedly connected to the side surface of the second sieve plate 42. One end of the first screw 45 is fixedly provided with a rectangular rotating rod 47, and the rectangular rotating rod 47 passes through the sieve plate body 1. When the aperture of the sieve plate body 1 is required, the rectangular rotating rod 47 can be toggled to rotate the first screw 45, and the square sleeve 46 mounted on the outer surface of the first screw 45 moves, and the square sleeve 46 can drive the second sieve plate 42 to move. When the second sieve plate 42 hole moves, it intersects with the hole of the sieve plate body 1, thereby achieving the purpose of adjusting the aperture;

[0024] A semicircular notch 48 is provided on the outer surface of the rectangular rotating rod 47, and a second fixed block 49 is fixed on the upper surface of the screen plate body 1. A limiting screw 491 is threadedly inserted into the side of the second fixed block 49, and the outer surface of the limiting screw 491 is in movable contact with the inner surface of the semicircular notch 48. There are several semicircular notches 48, and the semicircular notches 48 are distributed in a circular array on the outer surface of the rectangular rotating rod 47. By rotating the limiting screw 491 so that its end enters the interior of the corresponding semicircular notch 48, the rectangular rotating rod 47 can be limited to avoid the rectangular rotating rod 47 from rotating during vibration screening.

[0025] Working principle: When the utility model is in use, the sieve plate body 1 can be installed in the installation slot of the equipment through the installation plate 3 and the installation bolts 31. The material can be filtered and screened through the sieve plate body 1, and the screened material falls from the discharge barrel 11;

[0026] In order to prevent the screen plate body 1 from being blocked, the motor 28 can be started to rotate the cam 281. The cam 281 rotates and contacts with the arc groove 291 provided in the protrusion 29, so as to lift the screen plate body 1. The round rod 21 slides along the inner surface of the cylinder 22, and the spring 25 is stretched. When the protrusion 29 is not in contact with the arc groove 291, the screen plate body 1 can be quickly returned to its original position by the force of the spring 25. When the limiting slider 24 contacts the bottom of the limiting groove 23, vibration is generated, thereby preventing the screen plate body 1 from being blocked and improving the screening efficiency.

[0027] When the aperture of the sieve plate body 1 is required, the first screw 45 can be rotated by toggling the rectangular rotating rod 47, and the square sleeve 46 sleeved on the outer surface of the first screw 45 moves. The square sleeve 46 can drive the second sieve plate 42 to move. When the holes of the second sieve plate 42 move, they intersect with the holes of the sieve plate body 1, thereby achieving the purpose of adjusting the aperture;

[0028] Then, by rotating the limiting screw 491 so that its end enters the corresponding semicircular notch 48, the rectangular rotating rod 47 can be limited to prevent the rectangular rotating rod 47 from rotating during vibration screening.
