This design not only ensures the collection of materials, but also prevents the materials at each level from interfering with each other. Different material collection angles are designed between the first funnel 6, the second funnel 7, the third funnel 8, and the fourth funnel 9, so as to affect the dispersion of the materials in the funnel. A larger material collection angle usually leads to a more uniform dispersion of the materials inside the funnel, avoiding excessive accumulation of materials in a specific area, thereby helping to maintain the stability and consistency of the screening process.
[0024] Reference Figure 2 , Figure 3 The second round tube 11, the third round tube 12, and the fourth round tube 13 are all fixedly connected with an expansion tube 15 at one end, and the first round tube 10, the second round tube 11, and the third round tube 12 are all arranged inside the expansion tube 15; the expansion tube 15, to which the second round tube 11, the third round tube 12, and the fourth round tube 13 are fixedly connected at one end, is connected with the first round tube 10, the second round tube 11, and the third round tube 12, so that the connection can be convenient for disassembly, cleaning, and assembly, and the sealing is tight and there is no cross-linking of materials.

[0026] Reference Figure 3 A V-shaped buffer plate 14 is installed at the bottom circular hole of the first funnel 6; the V-shaped buffer plate 14 arranged inside the first circular tube 10 can effectively absorb and disperse the mechanical vibration generated by the vibrating screen.
