Abstract
Description
Technical Field
[0001] This utility model relates to the field of material screening technology, specifically to a screening device for different particle sizes. Background Technology
[0002] Material screening equipment is a key machine in industrial production used to separate materials according to particle size. Through the vibration, rolling, or rotation of the screen, fine particles pass through the screen holes, while coarse particles remain on the screen, achieving grading or impurity removal. Common types include vibrating screens, drum screens, and fixed screens. The core component, the screen mesh, can be made of metal, rubber, or polyurethane depending on the material characteristics. This equipment is widely used in industries such as mining, building materials, chemicals, and food, effectively improving product quality and optimizing process flows. It is an important tool for ensuring production continuity and product uniformity.

The multi-stage screening unit is vertically installed inside the screening box, with its screen plate horizontally sliding on a support platform on the inner wall of the screening box. The screen plate is located directly below the feed inlet. The vibrating device is connected to the side wall of the multi-stage screening unit, and the weighing device is located directly below it. This utility model enables automatic mechanical screening, allowing for different vibration frequencies and screen specifications to be set according to different screening needs. After screening, the material is automatically weighed, reducing data errors caused by material handling during weighing, improving the accuracy of experimental material weighing, increasing work efficiency, and reducing labor costs.
[0004] However, in the process of using common screening equipment, the material is directly poured onto the screen, and it takes a long time to vibrate the material evenly on the screen, resulting in low screening efficiency. Therefore, a screening equipment with different particle sizes is proposed to solve the problems mentioned above. Utility Model Content

[0008] The material distribution assembly includes a mounting rod fixedly installed on the inner side wall of the screening box. A dome drive box is fixedly installed at one end of the mounting rod. A rotating shaft is rotatably installed at the bottom of the dome drive box. A distribution disk is fixedly installed at the bottom end of the rotating shaft. An eccentric guide hole is opened at the top of the distribution disk. A rotating motor is fixedly installed on the inner bottom wall of the dome drive box. The output shaft of the rotating motor is fixedly connected to the top end of the rotating shaft.
[0009] Furthermore, a screen is fixedly installed at the bottom of the screening hopper, and the mesh count of the lower screen is greater than that of the upper screen.

[0017] Beneficial effects:
[0018] 1. This screening equipment for different particle sizes uses a material distribution component installed above the screening hopper. A rotating motor drives the distribution disc to rotate, and the material is guided from the eccentric position into the screening hopper through the eccentric guide holes on the distribution disc. During the rotation of the distribution disc, the material is evenly distributed into the screening hopper, improving screening efficiency. This solves the problem of low screening efficiency caused by materials being directly poured onto the screen during the use of common screening equipment, which requires a long vibration time to evenly distribute the material on the screen.
[0019] 2. This different particle size screening equipment uses two screening hoppers inserted inside the screening box. During use, the screening hoppers with different mesh sizes can be replaced as needed to screen materials of different particle sizes. The particle size of the screened material can be flexibly adjusted. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 4 In this embodiment, a screening device for different particle sizes includes a vibrating base plate 1, a screening box 2 fixedly installed on the top of the vibrating base plate 1, two screening hoppers 3 slidably installed on the inner side wall of the screening box 2, and two material distribution components provided on the inner side wall of the screening box 2.
[0027] The material distribution assembly includes a mounting rod 4 fixedly installed on the inner side wall of the screening box 2. A dome drive box 5 is fixedly installed at one end of the mounting rod 4. A rotating shaft 6 is rotatably installed at the bottom of the dome drive box 5. A distribution disk 7 is fixedly installed at the bottom end of the rotating shaft 6. An eccentric guide hole 8 is opened at the top of the distribution disk 7. A rotating motor 9 is fixedly installed on the inner bottom wall of the dome drive box 5. The output shaft of the rotating motor 9 is fixedly connected to the top end of the rotating shaft 6.
[0028] Specifically, the material falls into the distribution disk 7 and is guided by the eccentric guide hole 8 to fall into the screening hopper 3 at the eccentric position. The rotating motor 9 drives the rotating shaft 6 to rotate, which in turn drives the distribution disk 7 to rotate, so that the material is evenly sprinkled into the screening hopper 3, thereby improving the screening efficiency.
[0029] Please see Figure 1 and Figure 2 In this embodiment, a screen 10 is fixedly installed at the bottom of the screening hopper 3, and the mesh size of the lower screen 10 is greater than that of the upper screen 10. Screening hoppers 3 with screens 10 of different mesh sizes are selected according to the required particle size of the material to be screened, facilitating the screening of materials of different particle sizes.
[0030] The screening box 2 has a fixedly installed limiting support bar 11 on its inner side wall, and the bottom of the screening hopper 3 is in contact with the top of the limiting support bar 11. The limiting support bar 11 supports the screening hopper 3, making it easy to pull out and put into the screening box 2.
[0031] Meanwhile, a limiting end plate 12 is fixedly installed on one side of the screening hopper 3. The limiting end plate 12 is located outside the screening box 2, and a handle 13 is fixedly installed on one side of the limiting end plate 12.

The locking rod 15 is adapted to the limiting end plate 12. Rotating the rotary knob 14 causes the locking rod 15 to rotate to one side of the limiting end plate 12, thereby locking the limiting end plate 12.
[0033] Please see Figure 1 In this embodiment, a receiving drawer box 16 is provided on one side of the screening box 2. The receiving drawer box 16 is located below the screening hopper 3 below. A feeding hopper 17 is fixedly installed on the top of the screening box 2.

[0035] Secondly, limit posts 21 are fixedly installed at the four corners of the top of the mounting base plate 20, and vibration springs 19 are sleeved on the surface of the limit posts 21. A vibration motor 22 is fixedly installed at the bottom of the vibration base plate 1. The vibration motor 22 drives the screening box 2 to vibrate, which in turn drives the screen 10 to vibrate for screening. The vibration springs 19 enhance the vibration effect of the vibration base plate 1.
[0036] The working principle of the above embodiment is as follows: the material is fed from the feed hopper 17 into the screening box 2, falls into the uniform distribution plate 7, and is guided by the eccentric guide hole 8 to fall into the screening hopper 3 at the eccentric position. The rotating motor 9 drives the rotating shaft 6 to rotate, which in turn drives the uniform distribution plate 7 to rotate, so that the material is evenly sprinkled into the screening hopper 3.
