By adopting the wavy sieve plate 2 design, the contact area and path length of the material in the screening process are increased, so that the material can more fully contact the sieve hole 201, thereby improving the screening efficiency and accuracy. The wavy sieve plate 2 can also effectively prevent the material from clogging the sieve hole 201, thereby ensuring the continuity and stability of screening; a plurality of support parts 3, connected in the sieve shell portion 1, the support part 3 is arranged under the sieve plate 2, for supporting the sieve plate 2, the support part 3 is arranged to be softly connected to the sieve shell portion 1, and the support part 3 and the sieve shell portion 1 adopt a soft connection design and are equipped with a shock absorber 304, which effectively alleviates the vibration generated during the screening process The vibration impact on the screen structure extends the service life of the screen body. The lifting seat 306 and the screw rod 307 adjustment mechanism on the support seat 303 allow the protrusion range of the sieve plate 2 to be adjusted according to actual needs, thereby enhancing the supporting force on the sieve plate 2 and maintaining the stability and screening effect of the sieve plate 2; the support part 3 includes: two connecting plates 301, which are respectively arranged on both sides of the sieve shell part 1; a plurality of support seats 303, which are connected between the two connecting plates 301, and the support seats 303 are in contact with the bottom of the sieve plate 2 to provide support for the sieve plate 2; a fixed plate 302, which is installed on the sieve shell part 1, and the connecting plate 301 is connected to the fixed plate 302; a shock absorber 304, which is installed between the fixed plate 302 and the connecting plate 301 to provide shock absorption for the connecting plate 301.
[0027] Reference Figure 4 and Figure 5 The support seat 303 includes: a moving groove 305, which is opened at the top of the support seat 303; a lifting seat 306, which is installed in the moving groove 305, and the top of the lifting seat 306 contacts the sieve plate 2 for adjusting the protrusion range of the sieve plate 2; a screw rod 307, which is connected in the moving groove 305, one end of the screw rod 307 is connected to the lifting seat 306, and the other end passes through the bottom wall of the moving groove 305 and extends to the outside of the support seat 303; a knob 308, which is set at the bottom of the support seat 303, and the screw rod 307 is connected to the knob 308. Through the combination of the knob 308 and the screw rod 307, the height of the lifting seat 306 can be easily adjusted, and the screening gap and screening effect of the sieve plate 2 can be adjusted to meet the screening requirements of different materials. The modular design of components such as the sieve plate 2 and the support part 3 makes replacement and maintenance simpler and faster, reducing maintenance costs and time.
[0028] Reference Figure 3 The sieve plate 2 includes: a plurality of sieve holes 201, which are opened on the surface of the sieve plate 2.
[0029] Reference Figure 1 and Figure 2 The sieve shell part 1 includes: two side plates 101, which are arranged on both sides of the sieve plate 2; two bases 102, which are respectively connected to the bottom of the two side plates 101; a connecting seat 103, which is installed on the base 102; a vibration seat 105, which is connected to one side of the side plate 101, and an elastic member 104 is connected between the connecting seat 103 and the vibration seat 105; an assembly plate 106, which is installed on the side plate 101 and connected to the sieve plate 2, and is used to limit the position of the sieve plate 2 in the sieve shell part 1, and the vibration seat 105 in the sieve shell part 1 is connected to the connecting seat 103 through an elastic member 104. This design can more effectively transfer the vibration energy generated by the exciter 4 to the sieve plate 2, thereby improving the screening efficiency. The buffering effect of the elastic member 104 also reduces the direct impact of the vibration on the sieve structure, thereby protecting the overall structure of the sieve body. The elastic member 104 adopts a stainless steel spring and a vibration-damping spring.
[0030] Reference Figure 1 , the vibrator 4 is mounted on the side plate 101 and is used to generate vibration to drive the screen body for screening.
[0031] During use, the sieve plate 2 is arranged in a wave shape between the two side plates 101, and the two connecting plates 301 are fixed on both sides of the sieve shell 1 respectively. The connecting plate 301 is connected to the sieve shell 1 through the fixing plate 302, and a shock absorber 304 is installed between the fixing plate 302 and the connecting plate 301. The height of the lifting seat 306 is adjusted by the screw rod 307 and the knob 308 to meet the screening requirements of different materials, ensuring that the sieve plate 2 is stable and the protrusion range is appropriate, and the vibrator 4 installed on the side plate 101 is started. The vibrator 4 starts to vibrate, and these vibrations are transmitted to the overall structure of the sieve shell 1 through the side plate 101. The vibration seat 105 in the sieve shell 1 is connected to the connecting seat 103 through the elastic member 104. The elastic member 104 effectively transmits the vibration energy generated by the vibrator 4 to the sieve plate 2. The sieve plate 2 starts to screen the material under the action of vibration, and the waves The shaped screen plate 2 design increases the contact area and path length between the material and the screen hole 201, thereby improving the screening efficiency and accuracy.

This adjustment mechanism enables the screen body to adapt to the screening needs of different materials and maintain the continuity and stability of screening. The screened materials are separated according to particle size. The materials that meet the requirements fall into the collection device below through the screen hole 201, and the materials that do not meet the requirements remain on the screen plate 2 or are further processed as needed.
[0032] In summary, compared with the existing technology, it has the following beneficial effects:
[0033] By adopting the wavy screen plate 2 design, the contact area and path length between the material and the screen surface are greatly increased, which enables the material to more fully contact the screen hole 201 during the screening process, thereby improving the screening efficiency and accuracy. At the same time, the wavy design can also effectively prevent the material from clogging the screen hole 201, thereby ensuring the continuity and stability of the screening.
[0034] The support part 3 and the sieve shell part 1 adopt a soft connection design and are equipped with shock-absorbing parts 304, which effectively alleviates the impact of vibration generated during the screening process on the sieve structure, reduces noise and vibration levels, improves the working environment, and reduces adverse effects on operators and the equipment itself.
[0035] The soft connection design not only reduces vibration impact, but also enhances the overall stability of the screen structure. At the same time, the lifting seat 306 and the screw rod 307 adjustment mechanism on the support seat 303 allow the protrusion range of the screen plate 2 to be adjusted according to actual needs.
[0036] The vibration seat 105 in the sieve shell 1 is connected to the connecting seat 103 via an elastic member 104. This design can more effectively transfer the vibration energy generated by the exciter 4 to the sieve plate 2, thereby improving the screening efficiency.
