The screening devices disclosed in the above patents basically meet the use requirements, but there are still disadvantages in the specific use process:

The inclination angle of the screen surface refers to the view angle of the screen surface and the horizontal direction, the slope of the screen surface is large, the retention time of materials on the screen surface is short, the output in unit time is large, but the probability of the particulate matter penetrating the screen is reduced, and insufficient screening is caused. Conversely, the smaller the inclination of the screening surface, the longer the material will remain on the screening surface, resulting in a lower screening efficiency. Therefore, the overlarge or the overlarge inclination angle of the screen surface is not beneficial to the screening of the materials, so that the angle of the screen surface is adjusted according to the actual characteristics of the materials in the screening process so as to improve the screening precision, but the current vibration type screening device does not have the function.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
